Recently a serious crime occurred two doors down from my house. The police are looking for the victim’s missing car. I had 59 hours of video to review to see if I could help, so I used VLC which does two very important things for this task. First, VLC can play a series of 1-minute files by simply dragging a folder into the playlist. Second, you can watch the playback at 64x speed.
I watched 24 hrs at a time by dragging in the “day” folder off the card. Then I cranked it up to 64x and watched for the car to come/go. Its surprising how well you can see big things moving at that speed. If I saw something curious, just hit the spacebar to stop, slow things down, rewind a couple minutes, and review at slower speeds. If there was actually something of interest, I simply did a screen grab to capture the timestamp and I could then move on.
I literally watched 59 hours of video in just a few hours (including some breaks and time to inspect curious things closer).
I post this because it took me a lot of research to get to where I was making progress. The answer is fairly simple and works quite well, once you know about VLC’s capabilities.
Note: I copied all the files off the SD card first and operated from a hard disk. Not sure the SD cards can feed data fast enough, but you really want a backup for situations like this.
