View Full Version : Can I reuse the first pass stats file after changing the bitrate?

I encoded a movie with Xvid in two pass mode. The bitrate was 800 kbps.

I want to increase the bitrate to 1200 kbps.

Can I reuse the first pass stats file that was previously created,
or do I need to create a new first pass stats file?

Xvid cares about the specifiied bitrate only in the second pass. The first pass is bitrate-independent, you can reuse the stats file.

Does this hold for x264?

Yes, and DixV.

I'm not that sure about x264. One can re-use stats only when original (1st-pass generated) bitrate and final (used during 2nd pass) bitrate do not differ more than +-10% or something like that.
