I had assumed (really bad idea, I know), that when the battery voltage got dangerously low, the camera could sense that, stop recording, and save the file. That may have been a bad assumption! I am doing a test right now with a partly discharged battery to see what happens to a file when the battery gets low. If the file is totally lost lost, I would not want to risk that. And knowing how many of the old 808 cameras had problems with the battery not lasting very long, the 20 min stop/save/continue sequence is not so bad after all.

I know there are one or two people working on an external power source for the camera, and perhaps they would still like to have a continuous recording option? If so, please respond to this post and I'll advise my contact accordingly.
Tom, for me, I need an external USB battery power supply with which I can record +6 hours continuous video. Since there is always the possibility of the USB being disconnected, I don't want to lose all my data, so I prefer 20 min stop/save/continue any day (as I stated in a previous post).

Will the internal battery (if partly charged) take over if I disconnect the USB while recording? What happens if I reconnect the USB after a few seconds? I am hoping that the camera continues recording without interruption, and will continue until the card is full. If this is not the case, then this is a BUG, IMO.

Now about your firmware idea. Its a bad idea How is the manufacturer expected to supply and keep synchronized 4 different firmware versions?
(timestamp on + split files, timestamp on + big file, timestamp off + split files, timestamp off + big file).
Also, there is always an element of danger when updating firmware. I hold my breath every time I have to update my motherboard, video, router, telephone etc.

There is only one clean solution, and that is a parameter file similar to that used for setting the time. If the camera has been designed with too little internal memory, then it most probably won't be possible to use a parameter file.

My suggestion for your "HD camera guy": (to replace the current date file - forgot the name)
File name: Params.txt
File Contents (// is comments, should be ignored by firmware so that we can have a documented parameter file):
Date: 20110112 // YYYYMMDD
Time: 150549 // HHMMSS
DateFormat: DD.MM.YYYY // or any combination, e.g. MM/DD/YYYY, MM/DD/YY, DD-MM-YYYY, etc.
TimeFormat: 24 // or 12 (with AM/PM)
Timestamp: OFF // or ON
Split: Y // or N

This is similar to a suggestion that I believe you made yourself and is similar to the (old) DOS/Windows ini files.
The order should not be important and using parameter names makes the file flexible if other parameters are added at a later date. The file should be automatically deleted once the parameters have been set.

Any serious firmware programmer should have used a configuration file from the start, but I doubt that the programmers have a clue what end users want or may want, which is a pity. Maybe through you, we have at last a chance of telling the manufacturer what WE want.

Keep up the good work, and maybe you will go down in Keychain history
