View Full Version : Is 3 passes really enough??

I recently started using that profile too (for my iPod Touch). I noticed the default bitrate on that mobile setting is probably a little too aggressive and is likely to pixelate. I'd suggest you change it (upward). You do that by double clicking on the option in the mobile settings window, typing in the new bitrate, and saving.

The new bitrate should be? :rolleyes:
Also, is it worth it having DVD-RB run 2-passes for such a small device?

I played with it a little last night. One little trick: if you set the video bitrate to any value less than 32, DVD-RB assumes you want to encode with a constant quantizer. I set it to 5 and single-pass. It looks pretty good (good enough to watch on my iPod's 3 1/2" screen, at least) :).

Could you elaborate. When I doubleclick on this option(16:9 (640x360) 800kbs) the default Video Bitrate is "704", you changed this to "5"? I'm probably reading this all wrong.

Yes. You change the video bitrate to "5". That will produce a constant quality encode with a quantizer value of 5.
