[gentoo-user] [OT]: Converting flv to what?

[meino.cramer]

Hi,

As a Blender-fan over the time my harddisk has been filled (by me ;) )
with lots of video-tutorials in the flv (flash video)-format.

Now I need some space to store more *.blend files ...

So I think I need to convert the flvs into another format...

What is the most recommended format to preserve as much as possible
of the original video and audio quality *and* to save space beyond
the "some kilobytes" area?

What is the best tool for that job: mplayer or ffmpeg or...?

What parameters should I use ?

Thank you very much for any help in advance!
Have a nice weekend!
Best regards,
mcc

I would just keep the original, but that's just me.  Converting them
you're going to lose quality to some degree or another.  Just burn them
to an optical disk or something.

Barring that I use ffmpeg, but it's really just a matter of whatever
you're more comfortable with.

why convert at all? Burn them to a disk - or move them to an external drive. 
Which codec did you use for the flash files?

+1

Frankly, I would just buy another drive. The things are dirt cheap 
these days, much much cheaper than the cost of my time fiddling with 
transcode settings.

If you use:
   alias mplayer-identify='mplayer -vo null -ao null -identify -endpos 1'
   mplayer-identify /path/to/file.flv

you'll probably find that they're encoded in h264, anyway.

I've actually got some .flvs here that are encoded in VP6, but h264 is much more common, the most common codec for flvs on the web, and it's about the best codec out there at the moment. For image quality vs size, you won't get much better.

I would prefer my video files in a nicer container, such as .mp4 or .mkv, but that won't make the files any smaller. 

You'll need to transcode to get smaller sizes.

As the others have said: transcoding is a fundamentally lossy operation, and I would avoid it. It's also slow.

There's also the midentify command, which is a shell script wrapper for
mplayer -identify.

Many thanks! I wish I had known this sooner!
