Hi and thanks for your reply,
Apologies about the console output--I'll take another pass at this. I've
just downloaded the 4/18/2017 64-bit static version from the website (I was
using Jan 2017 before) and I'm having a similar result. The first 0:7:30
are in color, but the color gets lost after that. The console log is
length, but I'll put it into a pastebin.
I'm using the following command:
ffmpeg -i 19000500.sec -bsf:v h264_mp4toannexb -c:v copy output.avi
And here's the console: https://pastebin.com/34b40g6R
The result is a file that loses color about 0:7:30 into playback.
