The screenshot is from mpeg2 @ 36Mbps.

Screen (http://1.0.1.img98.net/out.php/i451912_scr-mpeg2-36mbps.png)

I want to achieve this quality on DivX.

What do you think?

What birate will do it?

25Mbps?

Try 1-pass quality based encode with CQ2 and see what bitrate it will give you. Needed bitrate for transparent quality is source dependent and no one can tell you what bitrate you should use by looking a single screenshot or even whole video.

I've tried XviD 1.3.2 (with all setting on highest) and it produced a file with ~27Mbps.

It's a bit funny that DivX produced a file with 46Mbps.

I'll try 2pass ~27Mbps DivX.

Thanks for the tip :D

Why would you waste so much bitrate on such a horrible source?

From that screen shot it looks like it was a SD source, upscaled to HD with the worst possible resizer (or maybe the source was already very bad). It's also puzzling why anyone would encode this @36 Mbps, no matter which encoder.

Re-encoding this @1 Mbps would probably look better than at any higher bitrate.

I've tried 13.3 Mbps and it resulted in a lot of noise.

Then I tried 17Mbps and it is very good, but it's also quite noisy.

DivX allows 20Mbps as highest birate for HD 1080p Profile, you can go higher but I think that there won't be any quality improvement, probably the codec was built for 20Mbps as highest birate.

So 17 Mbps with Denoise and then Sharpen shaders that are builtin in MPC-HC and it looks like the image is better than the original source.

It looks almost like a lossless rip made from Blu-ray disc.
