Hi, I'm using megui as encoding program, but can't figure out a good value for constant quality. I tried with 18(I forgot to mention that I'm encoding anime), 17 and so on, down to 12. I didn't tried it on some very high motion scene with a lot of movement, but I don't see a difference in the quality. But what's bothering me is the filesize. At value 17, I got 105-110mb for 00h:21m:20s. video with resolution 720x480. I don't think that's an appropriate bitrates(688kbps) for a video of that range and resolution. I'm I wrong, or not, and that's a good bitrate for 00h:21m:20s video with 720x480 resolution in x264(mkv)?

Could I ask you WHAT you're re-encoding?

I'm encoding Madlax episode 11, there's not a lot of high motion scenes in that one(I would say there isn't any), but still I'm not shure if that's an appropriate bitrates for it.

So you're not re-encoding? Well, I'm no encoding wiz, but I think most encoders use variable bitrate.

Well, it depends a lot on how much you've de-grained or smoothed the image, and what other x264 settings you use. For instance, disable MBTree and watch your bitrate double. Constant Quality (--crf ...) is the right approach, as it automatically adjusts quantizer and therefore bitrate to suit your needs (as opposed to constant quantizer --qp ... or target bitrate --bitrate ...).

I'd say that you should probably use --no-mbtree and/or bump the CRF up to the 14-15 range if you're worried about the filesize being too small, but if the quality is okay, why are you complaining about a small filesize? There's nothing wrong with that. That's the whole point of compression after all.
