I posted this as comments under this related thread. However, they seem to have gone unnoticed =(
I've used
ffmpeg -i myfile.avi -f image2 image-%05d.bmp
to split myfile.avi into frames stored as .bmp files. It seemed to work except not quite. When recording my video, I recorded at a rate of 1000fps and the video turned out to be 2min29sec long. If my math is correct, that should amount to a total of 149,000 frames for the entire video. However, when I ran
ffmpeg -i myfile.avi -f image2 image-%05d.bmp
I only obtained 4472 files. How can I get the original 149k frames?
I also tried to convert the frame rate of my original AVI to 1000fps by doing
ffmpeg -i myfile.avi -r 1000 otherfile.avi
but this didn't seem to fix my concern.
ffmpeg -i myfile.avi -r 1000 -f image2 image-%07d.png
I am not sure outputting 150k bmp files will be a good idea. Perhaps png is good enough?
this worked for my video i recorded off my pen camera
Using
-r 1000will force ffmpeg to simply duplicate (or drop frames if input fps is higher) the frames to reach 1000. Probably not what you want.
