1CD Encode + Lower Resolution = Better quality?

[Superturtle]

Will I get better quality 1cd encodes using lower resolutions?

assumming you're comparing single CD vs. 7 floppies, then, sure, low rez cd will give much better quality.

I was going to point you some info Doom9 wrote some time ago. It describes how 'bitrate works in relation to pixels quantity'. However, I can't find it!

I can only give you my opinion. I do whatever it takes to maintain low quants, thus generally speaking lower resolution is required for hard to compress movies that I must fit in a small space such as 1 CD. To me, this looks better than just encoding at "640 x whatever, damn the quants." I use a compression test to determine which resolution I use, generally aiming for at least 65-70%.

Hello, Mr, JohnMK,

I am assuming that you are referring to wide-screen movies. When I get a 2 hour full-screen movie, unfortunately I need to reduce the resolution for "480 x whatever".

My actual configurations for DivX 5.1.1 are: no profiles (GMC and Bidirectional Encoding checked), no Motion Vectors, use Log file, no Psy Effects (truly it's better, I have done a lot of experiences with that), 1st pass encoding at standard quality, 2nd pass the same, 3rd pass the same and 4th pass at slowest quality. That's the best configurations I've reached until now, after reading the Official DivX 5.1.1 Guide, the guides of Doom9.org and other guides along the net, and making tests for months.

Do you have any suggestion to raise my "480 x whatever" resolution for full-screen movies withou getting a "debris-through-the-edges-of-contrast-colors quality"? :confused:

Thank you very much,

Unfortunately, full screen movies are just as problematic as you describe there really is no win-win resolution, if you'll pardon the pun. It can either look sucky because the resolution is low, or sucky because the quants are high. My preference is still to keep quants low, however.
