Reduce Size

[kamyogi]

HI,

I want to reduce the size of a video file so that I can send it through android mobile phone. The file is in mp4 format and is about 38 MB. I want a file of around 15 MB, it does not matter if there's a slight loss in video quality.

My OS is Ubuntu 12.04 (Linux).

Is there any solution?

Thanks for your reply.

So

ffmpeg -i video.mp4 -c:v libx264 -preset slow -crf 22 -c:a copy new.mp4

Increase the crf value for smaller output file size.

Or use a constant bitrate, replace then -crf with -b:v 1000k

Or get avidemux for ubuntu if you prefer a GUI. It works the same though. You set the video to avc/h264/x264 and adjust the bitrate or constant value to adjust the output file size.
