ffmpeg command creates a file too big
I run this command:
/usr/bin/ffmpeg -i “inputfile.avi” -sameq -ss 0:0:0 -t 60 “outputfile.avi”
And I get the correct 60 seconds video, however the file size is 300MB, while the original 20 minute long file is 170MB….
what is wrong? how can I fix this filesize problem? -

I would like to see the full terminal output to correctly diagnose but:
I am guessing that it is a combination of using the -sameq flag and not specifying a video codec. The full command line output will verify that.
Instead of using “-sameq”, try using “-vcodec copy” which will not recompress the frames and should result in a more realistic file size.
