Cropping video with ffmpeg

What didn't work:

ffmpeg -ss 00:08:05 -t 00:09:34 -i file.mp4 -pix_fmt yuv420p toji.mp4

What worked:

ffmpeg -ss 00:08:05 -to 00:09:34 -i file.mp4 -pix_fmt yuv420p toji.mp4

It should be ss which stands for start time and to which stands for end time.

What took the least amount of time:

ffmpeg -ss 00:08:05 -to 00:09:34 -i file.mp4 -pix_fmt yuv420p -c copy toji.mp4
