ffmpeg, first second of cut video part freezed I use this to cut a part out of a mp4 file:

ffmpeg -i input.mp4 -vcodec copy -acodec copy -ss 00:36:18 -to 00:39:50 output.mp4


It works good but the video image is always freezed in the beginning for 1 second.

Doesnt matter which video file I try and cut a part out of, it takes like 1 second before the video start.

Heres an example: 
                
            

Why?
The order of the parameters is very important on ffmpeg.
Try this:

ffmpeg -ss 00:36:18 -i input.mp4 -vcodec copy -acodec copy -to 00:39:50 output.mp4


It seems that setting the -ss parameter before -i sets a keyframe at the beginning of the newly generated video.
Or so I understand from the Wiki page here.
