Of course the better way would be just outputting the original 16:9 video full frame in anamorphic widescreen ("stretched into 4:3" if you will, that's the observed effect).
The anamorphic thing is very simple to explain: just fill the whole 4:3 image up and down so no black bars will appear. The signal is delivered with one more flag for the aspect ratio of 16:9.
Regarding this flag is almost like the same thing as our 5fps recording played at 30fps. The MPEG2 standard which is used on DVDs support this 16:9 flag which also is in the IFO files but this IFO discussion is too much offtopic about DVD standard.
On a PC or standalone player you can play a 720x480 file which is supposed to be 4:3 on a 16:9 screen with correct aspect ratio only because that file have the flag about 16:9 AR.
Or you can play an anamorphic file without any flag if on your player you can set the AR for 16:9. If the FPV user have some gadget which can use 4:3 or 16:9 setting, no matter the flag delivered by the camera.
So I was expecting the developer to offer the 4:3 standard image and the 4:3 as anamorphic.

The camera is capable of outputting a standard 640x480 (un-distorted by any stretching of compressing of the image) video as is seen in the GUI Video Frame size setting. But this just crops off the sides of the native 16:9 image the camera captures, which loses a lot of the visible scene... not a good thing for FPV use.

Some of the SD 808 cameras output 720x480, which I didn't like because they played back with the scene stretched horizontally. I used to correct that in post processing to get back to proper proportions of the native scene.

My firmware update went great using the GUI.
My videos are coming out a bit dark.
maybe someone can list their settings for the "advanced settings"

#16 setup file

Few mounts ago I used my camera. Last week I changed SD card to 16G and now I do not have a file to change settings on the camera? I have Mac computer. I just formatted new card with SD formatter. I know that question was probably asked before but looking through 700 posts wow.
Maybe someone can help please. She is working fine but I turned sound of because I was using it with EDF and now I can't turned it back on.
Thanks in advance.

You can extract the camera configuration file from the camera with some button presses, then edit it manually. You don't need to read all the posts, just start with post #1 like the thread title says. The access the User Instruction manual linked in post #3 for more details on how to use your camera. And there is a GUI that will run on a MAC now, so download that as well to make setting the configuration easy. You probably need to download more recent firmware as well.

Did you even try changing any of the advanced settings? The Exposure setting will make videos lighter or darker, just like it says in the GUI.

Yes Tom, I have PAL equipment and due to my knowledge form German forums, at least many if not every German customer of Keycam #16 has the same problem with the vertical bars left and right. I don't know why they don't register here on RCGroups and report it, too.

Regards, Gerd

PS: If I select NTSC output at the keycam the vertical bars left and right will become more wide. So I guess the video timing for PAL is still not optimal.

I have taken a screenshot with my Hama Video Editor framegrabber to show you how it looks like, Keycam set to PAL mode and 16:9.

We have PAL system here but I only ever watch vids on my puter. Can't help I'm afraid.

I'm wanting to use my #16 on a Walkera Ladybird. I've weighed it at 17g with the MicroSD, but without the case it's only 10g.

Has anyone got any ideas on how I could make a lighter casing for it? I've got a micro 5.8GHz vtx hooked up to it, currently it comes in around 20g, but if I can loose 5g or so on the casing it would be much better!

I've found some battery connectors so I'll be seeing how the #16 battery copes with powering the vtx too, that'll keep the weight down.

There have been many attempts to save weight like this on these tiny aircraft, but most don't work as expected because:

1. You need to add connectors and additional wiring to make the connections - some weight savings goes away.

2. Most don't have a vtx on board, and try to power the camera from the flight battery. Then, the camera stops recording when the delivered voltage under load drops to about 3.7V. This is well above the point where there is not enough power to fly. One recent example I read only got 2+ minutes of video. Also the flight time decreases.

3. If you try to power the vtx with the camera battery, you also risk losing vtx video as well as the recording...

4. The minimal "case" for the camera would be some shrink wrap over the circuit board, but be sure to carefully secure the camera lens module to it with hot glue or silicone adhesive so it doesn't vibrate - this will also detract from the initial weight savings.

The camera battery comprises most of the weight savings. If it were me, I'd find a smaller battery that can power just the camera, so it records for just slightly more than a typical flight. The 250 mAH stock battery powers the camera for about 40 min. You'd need to do some trial and error due to the voltage problem, but you might find something like a 100 mAH lipo cell can power the camera for maybe 10 minutes. Then you'd have the best combination of weight savings, flight and video recording time. But, maybe there is some happy medium using a separate battery for camera and vtx as well, especially if losing the vtx is not critical because you have a friend as a spotter and you're not very far away?

Well, I have a +20-year-old PAL monitor and the 4:3 image shows absolutely perfectly, of course with the vertical distortion. No black bars at any side. If I select 16:9 I obviously get the black bars at the top and bottom.

In NTSC mode the picture is black-and-white, which is also normal on a monitor which was designed for PAL only.

On my PAL TV, which also supports NTSC, I also never get any bars at the side.
If I go thru the composite (SCART) plug on my recorder and then to my TV, I also never get any side bars on my monitor or TV. All test equipment used was not designed for HD.

So, to summarize, on my PAL TV/monitor equipment I always get full screen video when 4:3 is selected.

Thanks for the update. I tried outputting the video to my old NTSC cathode ray tube TV with 4:3 display. The video had a very tiny bit of black bars on the sides, but they were curved such that there was a bit of black in the middle of both sides, but none at the top. But I think this was due to a misadjusted pincushion correction circuit and not inherent to the camera output. I switch to PAL, and got slightly more pronounced version of the same thing. I believe I could eliminate the black bars entirely by adjusting the pincushion. But this is not something that a digital display has or needs.

I don't know if there is any kind of adjustment for this in the DSP chip that outputs the signal (I doubt it), but the developer reads this thread, so it's registered as an issue for consideration.

But are you also powering an FPV vtx on board as well like the original poster was?
