Identical firmware in identical #16 cameras renders the color very noticeably different with the two lenses. And it changes as the light intensity changes.
Sometimes it was barely visible to my eyes, like a shadow, and at those times the camera could not resolve any detail. I kept it as close as possible, just to check it out.

Yeah, maybe the coatings have an effect, possibly not uniform across the frame.

The pink spot in the video above may be a creation of YouTube for the video thumbnail. I find nothing like that in any of the individual frames. I'll upload to Vimeo to see how that looks.

The light falloff (a.k.a. vignetting) is normal. The focus usually is very slightly less defined there as well, but if the lens is properly focused, it should be pretty good at the edges, too.

BTW the hotspot is less visible when the video is played, don't know why. After looking at the video frame by frame, I see no frames with pink spot. It seems that it was created by YouTube for the title frame. (thumbnail)

Here's Vimeo, not so pink

I know why it's that.

It's because if youtube find that the miniature picture on the video is too dark and not much visible, it will automatically increase the brightness and maybe the saturation too.

Try to upload a dark video and you will see that the thumbnail is way brighter than the real video.

I'm using this camera for class at school - to record lectures (with permission, of course) given by professors who cover more material than I can capture by pen & paper.

Today, I did a side-by-side comparison of the end of one clip, and the beginning of the next, to see how much gap there is... about 3 seconds. That's more than acceptable, especially given the 50 min between-gaps interval. But, what really stumped me is the different field of view.

The camera was attached to the desk behind me with velcro. It most certainly DID NOT move. Yet, the endpoint of the left video shows the camera pointed more to the left. The beginning of the next segment (right image) looks like the camera was moved to the right. Notice the chair in the foreground, or the girl/podium on the left...

The video properties for both clips are identical (I can provide a screen grab if requested as well).

Does anyone know what would cause a shift like this? It's not critical, but, lining up a descent shot is hard enough without 'electronic' shifting of the video center mid-recording...

I would check the last frame of the first clip with first frame of the second clip. Velcro slowly releases some of the hooks, I can hear that when I use the cam on my cap, so maybe the camera crept slowly sideways??

Victapilot - the screen grab is just that. The last frame of the first clip is on the left, the first frame of the second clip is on the right. There was zero movement for the entire duration of both clips - so the odds that it moved in the short 3-second window where wasn't recording, is rather unlikely, IMHO. Although, I can't come up with any other explanation...

What I'm thinking is if the sensor on the camera is actually 1400 x 800 (hypothetically), but due to quality control (say the outside margins of the sensor are imperfect), cropping, and software limitations, the recorded image only utilizes 1280x720, then there is data that is normally 'disposed'. If something happens that causes the 'center point' of that cropped image to move slightly each time a recording is stopped/started, the the field of view would change marginally. I'm grasping at straws...

[edited to add] I just check several other lectures where there were multiple segments, and none of them had any shift between the end of one clip and the beginning of the other. So, perhaps you're right. The odds of that movement to occur precisely during those three seconds just seems unbelievable. Perhaps I should play the lottery tonight...

Sorry, I realized that you already did do what I suggested, but I had already hit the send button.

It looks to me that the second image is zoomed in a bit, look at the left edge of the whiteboard and the size of the speaker box. I'll try to duplicate with mine.

I picked out the glue with a #11 hobby knife and then twisted it anticlockwise while gripping the receptacle. Some people have ruined the camera doing this, but mine came out ok. Then just adjust focus by rotating

I tested mine, taped to a vice on my workbench, rock solid between clips too. I did like your technical explanation though

I was hoping you had discovered a new and hidden feature that we could use!!

The CMOS has 1280x800 visible recorded area... no way for any over-scan. Was there anyone sitting behind you that might have bumped the camera? It has to have moved, somehow.

Disable auto shut down, photo mode?

Hi!

I would like to use this #11 cam to take photos I was thinking of using a servo to trigger the shutter. The problem is in photo mode the auto shut down is active. This is my camera from Toms post #2

1 - Is there any way to disable the auto shut down? pic, hardwire, software, walkaround.

2 - Could you use a pic to trigger a servo say every xx seconds and still be able to be triggered by Tx?


I found this thread helpfull, but not quit sure how to apply to this camera, thats why I thought of a servo.

There's no way I know of other than a firmware modifcation, but the developer's focus now is on their #16 camera, which evolved from the #11 and has MANY user toggles available without changing the firmware, with four choices for the timed auto-shutoff function, one of which is to disable it!

2 - Could you use a pic to trigger a servo say every xx seconds and still be able to be triggered by Tx?
Probably, but it's easier to get a ready-made remote activated switch, triggered by a spare RX channel, that is wired across the two legs of the switch that close when the shutter button is activated. There are pics of the switch contacts posted in this thread... you may need to search on some key words to find them... not sure if I put a link in the FAQs for this. But if you want timed photos, then some additional device would be needed to handle the regular interval timing. But having said all that, the photo mode of the #11 is NOT good... it's a large upscaled image from the native resolution (1200x800 pixel) CMOS sensor, so there is very obvious blurring of the image. I've found it much better to just shoot the normal video, then play it back and go through frame by frame in the portions that have the subject you want to find the sharpest image, and just do a frame capture of that into a bmp, jpg, or whatever format you choose.

FWIW, the #16 still photos are captured at 1280 x 960 resolution, so it's a very slightly enlarged native resolution image to fill the vertical height from 800 to 960 pixels without stretching the image vertically out of proper aspect ratio. MUCH better still photos than the #11! AND, you can also snap frame captures WHILE RECORDING as well (requires brief contact of both power and shutter buttons, though, so not that easily implemented remotely)

I've been using Virtual Dub.
I find it takes the 364Mb .avi file from the 808 camera and makes it over 3.99 Gb as an .avi file.
And it's truncated at 4.1 Gb.. and it's 94 seconds shorter.
Why is this?

I assume (hope) you are talking about the #11HD camera video since that is all we discuss here... there are about 15 different cameras with the "808" key chain style, so that doesn't tell me much. There is a thread (The "mega key chain camera" thread where all the low res 808 cameras are discussed. And since the #11 does not record in AVI format, so you must be referring to a different camera or are using a video already re-encoded in AVI format.

You probably have the video compression set to "uncompressed", so it takes each highly compressed frame from the native video, decodes it to a full (and MUCH, MUCH, MUCH larger) uncompressed .bmp image, then outputs the video in that format. Huge files are the result. You need to select a codec for re-encoding to a new compressed video. H.264 produces the smallest files, but you need to get access to it. See the FAQ editing tips for details.

I don't understand your comment about truncating it at 4.1GB Unless you trimmed off some of the original, you should not lose any video. And if you did not change the frame rate, it should play back in the same amount of time.

I'll use your suggestion of running in video mode and capture pic from video. I have a #16 coming I hope the new camera will support continuous recording in photo mode. It would be nice to have a tiny still camera,but if it does'nt will use the above method.

.
The inflated file in Virtual dub is over 4Gigabytes.. like 6 or so. VD won't put out a 6Gb file; stops it at 4Gb for a single file. FAT32 limit.
Selecting the "segmented AVI" output results in 2 (or more) 2 Gb files, labeled xxxx.o1.avi, xxx.02.avi.... etc... see the VD-RAW files in the image.

The #16 does not support continuous photo shooting. It is, after all, first a tiny HD camcorder. The still photo mode is a side benefit, and there are better cameras available for shooting still photos.

It seems the small size and good HD ability (which is soon to get even better!), has attracted a huge following, and many uses do not coincide with the camera's built in features. There is no one camera that has everything, and neither will this one, but for shooting aerial video, this is the best HD camera that can be flown on just about any RC plane that flies. No other camera has that ability!

Haven't had much onboard view recording for some time while I've been busy on my brushless upgrade and practice flipping. Yesterday came across the kite-flying guy from last time so I stickied-taped my #11 to the underside of the canopy for some onboard footage. The bird had a dreaded wobble which I kind of fixed today. Made some more high-flying and surprised to see that my little bird can even flip and hover inverted with the #11 cam weighing almost a quarter of its weight!

IMO, youtube has gone much further since this thread first started. It can do 720p and 1080p videos and even post-process video with image stabilization. I'm usually not a fan of video/photo post-processing but this stabilization feature seems interesting. See if you like the stabilized version of above clip below. I find it cool at first but then it seems like by interpolating frames it takes out quite some details in the image. Let us know what you think!

I can't see any noticeable difference! With that much wild motion, stabilization can't tell when to try and stabilize and when not to. It's more suitable for smoothing out very small motion, like minor shakes and movement by a handheld camera. Wild aerial videos are beyond help...the artifacts introduced by stabilization can be just as visually detracting or annoying as the unstabilized video to my eye.

The YouTube stabilizer has settings from 1 (mild) to 10 (max).
The second half of this is at 10. Seems to work, but zooms in to hide the edge shake, and is more blurred.

The free YouTube editor is worth trying for folks that don't want to invest in high end computers

Sorry I have the cam removed from the heli at the moment. Installation is straightforward. I have the keychain covers removed as always. Sticky-taped the battery to the cam's PCB, whether I use it as onboard cam or cap-brim cam. For onboard cam, I just sticky-taped it to the underside of the canopy with a piece of foam sandwiched between.

But it also zooms in, blurring it and losing part of your scene with the decreased field of view.

If you refer to my clips, try watching the stabilized version a bit before going back to the original version and you'll probably notice that you get to see more details in the original version.

Yeah, I think that's the main reason causing the loss of details.

Still trying out youtube's "stabilize" feature. I think it loses too much details and I probably won't use it from now on. Convince me otherwise.
mCPx More High-Flying and Flipping [stabilized version] (5 min 24 sec)


Was having so much fun with the onboard cam I decided to use the roll of trees on the sidewalk as a slalom course. I started off slow but figured it would be more fun if I flew faster and tighter thru' the course. I was planning to walk alongside but by the 2nd tree I couldn't keep up and misjudged distance. I thought I cleared the tree and started banking. Bam! It hit right on, blade vs tree! Canopy (with onboard cam sticky-taped to the bottom) totally ejected and flew 3 ft away. One blade was broken in halves. Everything else damaged bent back in place.

Oops! We've all been there. I recently sheared off the top wing of my biplane thinking I was past a hanging power line when, in fact, I wasn't.

Here's a short video of my Radian with onboard #11 and wide angle lens.

Nice video Mclarkson! Very clear.

@race miata, the stabilzation might work from a hover, but will have a hard time while both shaking and panning. Some of the high end deshakers allow you to identify key features to stabilize, such as the goal posts in a football game, the highlights will then be kept steady even if the camera shakes.

I agree with you so won't try to convince you otherwise. And as your video shows, stabilization does not work to fix the vibration-induced "jello" waves. It cannot work, because it only shifts around and zooms entire frames to try and keep portions in one spot. The vibration waves are built into each frame image by the camera's rolling shutter, and are constantly moving as well. They can't be removed by the deshaking frame shifting magic.

p.s. I loved the slalom video!

p.p.s. Your weather is now reaching

Flying over white stuff

After a night of mild light snow, the sun came out today! Couldn't pass up this flying opportunity over the white stuff. Said to myself "don't land on the white stuff". Turned out it was quite windy (32km/h wind) and it blew my bird out of orientation and crashed. Ironically, it was the white stuff that cushioned the fall. Time to dismantle and clean up my bird.

Video is still uploading but don't get too excited. Image is quite wavy. Unfortunately, the attached screenshots might be more pleasant to watch.

EDIT: Video ready.

I put one of mine on the S032. Lifts it nicely. Took it outside, but a low battery plummet from 50' broke the camera. Sob!

CMOS scanning is the culprit. Line by line, starting at the top of the image.
Each line could be readjusted to eliminate the waves........ I crack me up!

I'd buy that camera. The 30° field of view of the standard lens just sucks!

I flattened the lower case on the 808 to get a nice base for it to rest on, instead of building a support to position it. (belt sander)
And found using the flattened base only was good for keeping the lens stable, when the top of the camera was removed for weight purposes.

HK 120 Lens??

Where do you get this lens and how difficult is it to install? This 30 degrees is nonsense. My last cam was 46 degrees and that was even a little small.

What camera has a 30 deg. lens?.... not the #11. It is close to 60 deg.

No it ain't!
The horizontal field of view is just 30°.
Laid out a fan 20 degrees on each side, placed at 10" from the camera.
The three cameras I checked all have a 30° field of view.
The opposite corner thing which leads to a higher value is only useful for selling tvs.

OK... you're referring to the horizontal field of view.... I'm referring to the AOV of the lens, which very definitely IS important, unless you don't want to see any video image in the corners of your field of view!

The AOV was tested very early on for the #11 with photo images of the tests posted. If you are so unhappy with the #11, why don't you just get the HK camera?

Wing lens at HK

Anyone have the link to HK for this lens? Also can I buy just the lens?



QUOTE=victapilot;20198038]The HK Wing (720p) lens has same dia and thread as the #11. I removed the lens of my #11, it was quite easy, seems to be locked with a dab of clear green Glyptal type solvent based sealer. I unscrewed it carefully, removing all traces of sealer and dirt before final removal.

The CMOS looks about the same size as the one in the HK Wing camera, so that's good. Focus is still rough, about two turns out from full in.

I hope this will have the benefits of both cams - #11 light weight (18.1g with new lens), great video processor and format, the HK lens has 120deg aov and less vignetting.

Video - still work to do, but vignetting minimal

I'm not completely done, there's a better video about 2 pages ahead. I see good focus on the right 2/3 of frame, the focus on the left 1/3 is closer. So I put near objects on the left. The reason is, I believe, that the lens receptacle is not true to the cmos, or the cmos is not flat. To fix would be risky, maybe heat the cmos receptacle with a heat gun and straighten...

Maybe the HK lens does not fit real snug in the CMOS base module? Can you wobble it in the holder? It wouldn't take much at all to produce the varying focus across the field of view.

Lens geometry

The basic lens on some 808 cameras has a 30° FOV horizontally, and all of 35° diagonally.
A 120° lens (diagonal measurement) should take in a field width of 36 " on the diagonal at 10".

Here we are only talking about the #11 808HD camera. And this is where the lens AOV was determined.

LORDY!
What is the difference in the lens fields of view in any of these!
GEEZ!
With the wild claims of this and that camera from all those vendors, many selling junk....
What is unique about an #11 that makes it immune to the principles illustrated?
Or the #3, the #4, the # any number at all!!!!

Well that's why I'm only trying to focus on the #11 camera here. I'm testing a new 70 deg. AOV lens sent to me by the developer of the #11 (and #16 and new 1080p) camera, and I can just barely see a bit more field of view from it compared to the standard #11 lens.

All of the sudden, the video off my hd keychain cam is more pixelated than it used to be.

Is there a way to refresh the software, if that's the cause.

Many people like the #11 just the way it is. You should consider the #16 camera, which is being tested with 90 and 120 deg. lenses in addition to the standard lens which is close to 70 deg. The #16 has evolved from the #11 with many user configurable features, along with possible lens options.

FWIW, the firmware color control can react very differently with different lenses, so it's not necessarily a plug and play option as far as image color is concerned.

They are not available yet! The #16 developer is working with a lens manufacturer, so these are not lenses you can buy somewhere yet. I mentioned they are being tested. The developer will not sell junk, so they have to be tested for their visual quality and how they work with the firmware. And we know that different lenses can produce different color results with the same firmware. And the firmware for the #16 has an updated version with better color control in BETA testing right now being finalized for release. So first things first.

I'm sure that the answer is somewhere in the 570+ pages of this thread, so a link will be considered as a great help!!!

I've had my #11 keycam for about four months, and then a couple of weeks ago it suddenly started 'burning out' in multiple colours on the brighter areas. It does it on two computers, and two different media players.

Anyone any idea what's causing this, or is it just b@ggered???

I hope they will keep the firmware updated on the #11 camera. I haven't got the #16 yet but the video looks great what I have seen so far. My birthday is in February maybe I'll get a #16.

I get the same as you : see here

Tried all solutions - still the same

I can only think a firmware upgrade can *maybe* fix this

Won't be investing in another 808 ...

This question has already been posted and answered, but since there was a typo in the original posting you wouldn't easily find it

I answered the question here and Giorg has a comparison chart here. Scroll down to 17. December.

You cannot set the parameters in the #11, but there are different firmware versions for the clip lengths and the timestamp being shown / not shown on the video.

The #16 parameters can be easily set with a Windows software tool, so you only need very basic computer knowledge to set the parameters.

Giorg's excellent blog should tell you everything else you want to know.

Battery is probably dead. You need to order a new one and install it. You need soldering skills.

Dont know if it'll help anyone, but I contacted the seller, and they said: "I think the problem is with the connection between the camera module and the PCB board. It might get damaged somehow. One or two soldering joints of sensor FPC might get broken". I have returned it for a replacement - but with it being Chinese new year, I won't be expecting another for a few weeks yet!!

These guys are great. I got a replacement from my vendor (eletoponline) when he determined mine was bad. It wouldn't charge the battery. I ordered 2 new extra batteries and it did the same thing on both. I sent it back for $2.50 postage and received a new one in return. Their communications are excellent via email and reply very fast.

Could be the battery, but the beep is strange...
First step is to check if the camera will record using the special cable.
There have been many posts, but not with the beep. Here are two recents links that may help you:
Link1, Link2, Special cable link.

If you still can't record using the "special" cable, then the camera may be defective.

This beep sound concerns me. Is it coming from INSIDE the camera? There is nothing in there that could make a sound when connected for charging unless something is VERY wrong in the charging circuit, or the battery has a catastrophic failure and its foil pouch has split open and is hissing as it relieves internal pressure when charging. I suggest you open the case and have a look inside before doing any more charging attempts or powering the camera from an external source (the external power connects to the battery in parallel and will also try to charge it) .

I would tell you to go over to the #16 camera thread and read there first,, as I find the #16 a much better camera and a lot easier to use..

#11 + lgp500

Hi!

I am taking videos with my carchain #11, then I took microSD card out of the camera and put it in my LG500 cell phone and chek videos. But it is complicated when you're in action so I wonder is there some cable aviable to connect #11 camera with LGP500 phone to check video directly, without taking out microSD card from #11?

Thanks for answers!

That was a well put together video, & the general feeling didn't need language.
Thank you.

Problems recording! Went out twice todat and did a 30 min recording came back, nothing on the card! Ok, went out again for a 15 min recording, AGAIN, nothing on the card. Now when im home and do short 1-2 min tests, all works fine! How can there be nothing on the card with the longer flights??? I hit the power button for a few seconds until i get the solid yellow light, then short press the front button and get the 3 flashes and then the led goes dark. I dont get it????

Maybe it's cold out.. And the battery voltage is dropping so low from the cold that it's shutting the camera off without saving the video first??

Your name says NJ..... I think there was a problem with them doing this.. what firmware are you using? Have you read all the Q&A to see if it's in there? On my #11 as the battery got lower it would start recording a noise but I never ran it till the battery was dead.. On my #16 I have and it will stop and save before shutting down.. And it has the flashing light to tell me it's recording.. One thing that I hate about the #3 and #11 was never knowing if I had turned off the camera or if it was recording or if it had died from dead battery..

Actually I'm on vacation. I need someone to explain how this camera functions when it runs out of battery or over heats. The video should be saving up to the error point

.
The three I have of various #'s are also the same way. Is it off or still on?
And two of them put the still photos in the same directory as the videos, instead of media and photo.
One won't take photos at all.

Not necessarily. The cam might only write a header etc to create a video file when closed normally. If the cam runs out of power while recording there is a risk of losing everything, or get zero length or corrupted files.

The Rel 2 firmware should be saving files on low battery power. Some Rel 1 firmware did not.

Tom, I just bought this a month ago. Im pretty sure it has rel 2 on it as it will record past 20 mon without creating a new file and also theres no time stamp on it. I just did a full charge and let the cam sit and it did record for 23 min. So what could be going on here? its possible that it did run out of power and shut itself down on the previous flights, could I have rel 1 on this camera even though its so new??

Is it possible? Sure! Not probable, but possible. And (I think) one of the REL1 firmware that had no date stamp recorded longer than 20 min. (it's been a while.. not sure anymore). You can always download and install the REL2 firmware posted in the thread link here to be sure.
