boxy picture

For some reason im getting excessive boxes on even low motion frames even at higher bitrates (like 1150). Any suggestions or things to try? Here are some of my settings, if this helps: Ultra High percision H.263 Max I-frame int 300 Min I-Frame int 5 Min I-Frame 2 Max I-Frame 6 Min P-Frame 2 Max P-Frme 16 Thanks so much, Jerets

Sorry, What do you mean by boxes ?. And what deocder are you using ? Tried FFDshow ?

excessive small boxes throughout the entire picture: I've noticed that most peoples don't have that many obvious boxes esp. in low motion frames. Thanks so much, Jerets note: be sure to view screenshot at max size

Tuning, Jeret means hes getting the "block" effect in his videos when encoding. This happens when there is a lot of high motion and the picture breaks up into distorted blocks. Smaller birate mpeg movies do this too. Jeret, i recommend going back to the older "stable" version of Koepi's XviD codec, as the new one still has a bit of work to be done before its stable. I too have also had the results that you are getting with the block effect. I recently went back to his older stable version. Oh got a question for ya Jeret. Did your encoding take insane amount of time? im on a 2.8ghz, and when i use DivX encoding usually takes just under 3 hours. But with XviD 1.0 Beta2 it took like 4-5 hours with even the basic settings, no extra options. did you have this problem also?

jerets, are you using 1-pass CBR? Maybe the bit-reservoir is drained from high motion scenes before. What is your source, what is the resolution?

Thanks for the responces guys. Tuning/Hylas: my source was 704x480 from an s-video source digital satellite. So no reason for anything to be wrong there. i was resizing to 512x384 and using 2-pass vbr 1150 which i thought was very liberal for any encode. Gknot4ever: i think i will be trying the older version. not sure what i was using but i do think it might have been a newer one. not sure. vdub says its: 9:17:45, Jun 11 2003 (Unknown build). Core version 2.1 <- is that the version your talking about being unstable? Also, the samples i've been working with do take a little while to encode... although i think it saves time if i open my final avs file in vdub(i like mod version) and directstreamcopy->save avi and then encode the saved avi. Thanks guys, Jerets

lol you guys got me all confused now. Tommy Carrot: i've seen many other ufc samples with a bitrate even slightly lower then mine that don't seem to have that many boxes. I do have ffdshow but wasn't able to follow ya on what i should do to check it? Open ffdshow configuration? I didn't see those options in there. Also, are you suggesting a new version of xvid then, "9:17:45, Jun 11 2003 (Unknown build). Core version 2.1". What version are you using? Manao: For some reason I thought 1150 was a high bitrate for anything. What would you recommend (for high motion sources like this)? 1250-1500 for high motion sources like this (before reducing the resize to 448x336)? What bitrate range would you then recommend for 448x336? 900-1150? Thanks so much, jerets

Jerets, you can find everything about the latest build in the looong thread titled 'Ciao! (XviD-1.0-Beta2-05122003)'.

One more thing, you said satellite digital cable. I found out, even the source isn't clean and will lead to blocking even more from there when I do my xplay episodes. I would also recommend either highering your bitrate and/or use a lower resolution. As well as use b-frames, if you aren't already. Also, you might want to use bilinearresize. Sure, you will lose a touch of quality, but it will help in the compression. I'm going to wait until XviD1.0 stabilizes a bit more, before trying it out. Sure, I want to try it out (oh boy do I ever), but I don't think it's stable enough to archive to it yet and I don't really have the time to install it and play with it. So I'm sticking with the previous release of xvid.

Wow you guys have been very helpful. Thanks so much. Just a couple more things. Manao: Where can i find Koepi's Statreader? I looked all over koepi's site and searched the forums here as well as google. Can't find it at all? I am now using this version of xvid "8:01:32, Oct 4 2003 Core Ver 2.1" <- is this the latest (best) stable version? I figured out how to use the FFDShow to check the quality. Works very well. =) Thanks again, Jerets
