the quality get bad when i convert to mp4.

[KanineN]

Hello!

When I am converting .flv files to .mp4 with ffmpeg the quality get bad. I use the code

ffmpeg -i name_of_file.flv name_of_file.mp4

But how can I make the quality better? If a .flv file is maybe 120 but when it's .mp4 the file is around 92mb.

Can someone please help me with my problem.

If you want to know something about ffmpeg, the absolute quickest way is to look at the manual page:

man ffmpeg

The setting you want is "video bitrate". The man page says that the bitrate is 200kbps by default. For video, this is a low bitrate. You might want to try the following:

ffmpeg -i name_of_file.flv -b 500k name_of_file.mp4

(you must specify "k" at the end of the bitrate in order to tell ffmpeg that you want kilobits per second, not bits or megabits).

A good tip is to find about 10 seconds of footage, and encode this using the new settings to check that it works properly. There's nothing worse than waiting an hour for some long footage to finish encoding, and then finding that you got the settings wrong.

ok, then I will try to convert on 500k to 1000k. Thanks!

you should check online for FLV Converters, most od them support a large number of formats.

**Edit**,

you may want to try some of the freeware converters available for Windows/Wine..
