ffmpeg - Quicktime to Quicktime


I use ffmpeg to convert MOV files to FLV files, but I need to do one that stays a MOV file and just tweak the size and quality. Can that be done with ffmpeg? Does anyone know the command line options?

The 'man ffmpeg' command will get you the documentation. If you just want to reduce the video bitrate, you can use the '-b' option.

MOV files usually uses lossy compression. This means every time you want to tweak it, it loses quality.

Go to http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html for the documentation. Typing man ffmpeg will not give you a manual for ffmpeg because it does not come with one.

Electro - Perhaps the package for your distribution(s) omitted the documentation, but 'man ffmpeg' on FC5 with the package installed from the FC5 repositories (the OPs distro) includes it.

If you compile ffmpeg yourself, it will not include any manuals.

If you install from source from the mplayerhq.hu site, when you perform the 'make' it will also execute with the "install-man" target. That's the equivalent of running:

make install-man

By default, make will try to install the files in /usr/local/man/man1, however the man files are not generated from the texi files by this process. In order to do that, you need to install the 'texi2html' utility. Without that utility, the conversion of the texi files will fail, and the subsequent installation of the man pages will fail.

I'm guessing that you don't have texi2html installed if you don't have the ffmpeg man pages.
