NO, the firmware would go until the 4GB files size is reached IF your camera had enough power. If you are using the "regular" #11 camera (not the jumbo with the larger internal battery), then your recording stopped because the internal battery was exhausted. The internal battery is only good for 30-40 minutes of recording. You need external battery power to record for longer periods. This information is in the camera specs and details in post #2... you did read that first didn't you?

I converted a native 20 min. #11 video from .mov to .avi using the MP4camtoAvi utility to get a lossless .AVI file (took 4 secs. to convert), then importing that into Vdub, and exporting with video set for "Direct Copy", NO audio, and frame rate set to 338 fps (to get the same speedup you referenced), which took 34 sec. So about 1 minute to produce that sped-up file even with the program changes.

The playback with WMP was jerky on my PC, which has a lot of memory and a fast video card, probably because the native h.264 video codec over taxed my system playing back at the fast rate. I did not have this problem when I converted an H.264 video to a .WMV file playing at 64x normal speed with a WLMM converted file!

<edit> WHOA! I rebooted my system because it was sluggish on several tasks I had running. Now after a reboot to clean up my system, that sped-up file plays back at full speed with no pauses whatsoever! <edit>

Got your post edit. That sounds great. I will go back to the video editing faq post and....read it again!

Thanks again for the help!

But I have not needed to use it for files which may have not been properly closed for some reason. If you try it and it works, please post back here. Good luck!

No luck with the file recovery software including "Recuva". However, I am able to recover my video file using just plain "CHKDSK /F". It convert the whole folder into a file named "100MEDIA" without any extension. I manually adding ".MOV" extension so I can double click the video file to run in the players. Few seconds at the beginning of the video isn't viewable but at least I get most of it out. Thanks Tom for pointing me around this direction.

I am now able to charge with a standard USB charger and record at once with my V2 camera! Just a small hardware modification (one 0R resistor removal) was needed: http://www.penguin.cz/~utx/hardware/...e_modification

The current camera circuit switches to mass storage or webcam mode whenever power supply appears on pin 1 of the USB connector. I plan to do more experiments and change the circuit to switch to USB mass storage or webcam mode only if USB data lines are wired to a real USB host. It is not so elegant as firmware change, but my camera would be fully charged after car ride recording aswell.

After this first step my camera never switches to USB mass storage nor webcam modes.

I have been researching this little gadget and I would like to buy one to mount to my rc car and rc plane. If anyone knows where to get one that is a little bit cheaper than 40$ please pm me.

Thanks for the feedback and for finding that the simple DOS CHKDSK /F command for fixing file structure from a Command Prompt also works with external removable flash memory! Good find! I hadn't considered this since the flash memory cards have theri own dedicated controllers mounted in the cards. I'll add this tip to my FAQs links.

<EDIT>
Here is a sample Command Prompt syntax for doing this, with the flash memory card showing up on your computer as drive E:. Replace the "E" with whatever the camera drive letter is on your computer when in flash drive mode:

"chkdsk e:dcim\100media /f"

Well if you buy cheaper version then this is not 720p, also is not #11, so don't expect quality as this one have. You can search on ebay, for 5-6$ but this has nothing to do with this topic... There is support just for #11

I did go through the external battery options in the thread, but the seller told me the camera would go for 90 minutes not 30. I guess battery pack it is.

OK, got my camera today!

First thing I did was a test recording. I only have an old 64 mb card so I only got a very short video, but I got a video!

Plugged the camera to my computer and it mounted perfectly. I found the file and played it in both Quicktime and VLC. It was basically a set if stills and sound but I put that down to an old (and slow) card and my crappy iBook. Will try a faster and bigger card soon and play it on my MUCH faster PC.

My cam has the time stamp so I will do the FW flash but I have some questions:

Tom states in the instructions:

1. Copy the appropriate firmware file (FW96630A.bin) to the camera's flash card root directory (the one that first appears when the card is recognized by the computer).

Am I supposed to see a ".bin" file in the root directory of the card if I formatted the card in the camera?

If I mount the camera on my mac I see two folders: "DCIM" and "MISC". Is the ".bin" file supposed to be in one of those two or should it be next to them?

When flashing is done, should the ".bin" file be left on the card or can it be deleted?

Also, and I´m sorry if this have been covered already, how does the charge light work on these? Will it go out when charging is finished?

Cheers!

I think this is very interesting! I checked out your site and I´m waiting for you to do some more finds on this matter. Please keep us updated!

Quick question... I've had my #11 for some time now but haven't used it much. It's been sitting unused for over a month at least. The last time I used it it worked fine, but now it seems the battery may be dead. I've charged it up, set it recording a clip, and it died in about two minutes. (Saved the file properly, end of file has the buzzing at 1 second intervals like when the battery gets low) I charged it up again, then tested the voltage, it was back up to 4.2V as normal. I started another clip, and it died in a few minutes again. I checked the voltage then, and it showed 4.11V, so without charging it, I started another recording and checked the voltage with it running. I watched the voltage drop from 4.11 down to 3.7 in about 15 seconds. Is it safe to assume the lipo cell itself has died and that replacing it will let me use the camera again? I've got some broken #8s and #3s that should have good batteries, can I use one of those?

Keith,

To me it sounds like the battery is a goner. Thing is with the LiPos that they don´t like to be stored at full capacity. One should store them at about 3,7 V/cell and since the #11 uses only one cell this is the voltage one should aim for.

Also LiPos are sensitive to deep discharge and overcharge. I´m not 100% sure but I think the voltage are 3.4 V and 4.2 V. 3.3 V and 4.3V could kill the batt.

When LiPos are used in these applications it very hard to have control over the voltage but when using LiPos in RC-stuff there are a lot of different products for this.

It probably was stored at full charge... I usually do a store charge on my R/C lipos, just never put much thought into this little camera one.

For anyone else wondering, the #3 lipo looks identical to the one in my #11, even the number on it was the same. The broken #3 has been sitting around over a year, the pack measured 3.8V. I soldered it in, and recorded about 5 minutes with it like it was, and it wasn't dead yet, so that's a good sign. I'm charging it now, will test later and report!

It doesn't matter where you format the card. You will not see a .BIN file until you copy one to the card yourself.

If I mount the camera on my mac I see two folders: "DCIM" and "MISC". Is the ".bin" file supposed to be in one of those two or should it be next to them?
It should be next to them. The root directory is the first one that opens when you click on the camera icon.

When flashing is done, should the ".bin" file be left on the card or can it be deleted?
You must not have read the instructions fully or have forgotten the procedure. Go back and read the instructions for flashing in new firmware. This question is clearly answered there.

Also, and I´m sorry if this have been covered already, how does the charge light work on these? Will it go out when charging is finished?
Yes, it has been asked and answered before, but this is a self-help thread. Go to post #3 FAQs and you will find the answer.

Cheers!
