Hi all!

I'm really looking for a good method for converting movies to flv files. I would like to achieve similar quality/size ratio like on megavideo or putlocker on linux, preferably with command line tool like ffmpeg or mencoder.

I'm currently using ffpresets with x264 in ffmpeg… my problem is that

1) my quality is better and size is the same as megavideo/putlocker video but the encoding needs too much time (hq presets with ffmpeg vcodec x264)


2) on faster x264 presets with same size like megavideo/putlocker the quality is worse: more blocky and darker (i noticed that x264 encodes are always darker even with hq presets – i don’t know the reason)

I know that megavideo /putlocker isn’t using a very CPU intensive script, after all they have to encode a lot of videos in a reasonable time, also

So please, if you have a good and fast command line encoding method for flv, or some advices, please post it. It doesn’t have to be top quality, just similar to putlocker/megavideo: little bit blurry but smooth withouth too much blockyness, and as bright as on the two mentioned sites.

I hope you can help me!

Thank you!

Apathetic: yes, i am using it, but i kinda need some more specific details, like the exact command line (encoding parameters, filters, etc).
Mindy: thank you, although i would prefer a command line method, not involving php. (but i will look into that script, the ffmpeg command should be in there)

So thanks, and i'm still waiting for some advices!
 
Here is what I got from Megavideo:

As you can see, they're using x264 codec, with High Profile, and 8 reframes! That's very CPU extensive! :blink:
 
exandeer: yes, it seems it is a hella good converter with a really good CPU... anyway, thanks for the help! For the others too, although i'm looking for command line tools.
