    Hi folks,

    I have footage from a Drift Ghost Stealth 2 headcam, but the video is black yet there is audio.

    Information in Quicktime says the format is:

    Ambarella AVC encoder 1920x1080 AAC 48000 hz Stereo L,R
    FPS: 29.97

    Interestingly enough, the file size is 254.1 MB. I would think that something of this length would be in the 1-3 GBs based on previous recordings.

    No issues with previous recordings either.

    This issue happened for 3 videos and then we took a video later and it was perfectly fine.

    Nothing was blocking the camera lens either.

    Any websites or services out there to maybe reveal or show the video?
    It's a very neat situation for which the video would be compelling.

    TIA!
    Cheers,
    Keebler

    Maybe try a different video player like VLC. Could be that the clip is just corrupted & you may be SOL

    Thanks. I've tried a variety of players. Tried ffmpeg and MPEG streamclip.

    I think I'm SOL because the file is only 254 mbs where as a 28 min video would be closer to 1-2 GBs :(

    I'll keep trying though.

    Thanks!

    Give this one a try, just download the trial and see if it can recognize any kind of video and if so, well you get half for free at least: http://grauonline.de/cms2/?page_id=5

    Thanks Gwendolini. I meant to reply back that this didn't work. Great little app though. It said it wouldn't recognize the camera file. :(

    Then there is really no salvageable data as it seems. Sorry for your data loss.
