[FFmpeg-user] How about multi-pass encoding for H264?

Now I use 2-pass X264 encoding to transcode videos to flv format.

Someone told me that 4-pass will reduce the size of the output file.

Is that true?

I searched much material, but found nothing useful!

How can I use 4-pass encoding.

Does any one know?

Thank you !
