MPEG-4 XviD Koepi 24062003-1 Encoder Guide
Hello guys,
a new version of my guide is available now. MPEG-4 XviD Koepi 24062003-1 Encoder Guide: - B-frames settings changed. - 2.1. Ripping and demuxing: The use of the overall track gain is useful for 6ch AC3 tracks. If you are dealing with 2ch AC3 tracks, then it is probably better to use hybridgain. - cosmetical things Comments, critiques, etc. are appreciated. Regards

just one thing at the first read. your comments on vhq is a bit contradictory. afaik, all modes of vhq is safe now, no harm on quality (syskin's comment) with b-frames activated a new scene change detection algo kicks in. it's more sensitive than the old one (syskin, koepi). vhq1/mbf0 (no b-frame, new scd) works fine but max i-frame not kept (my comment :-( vhq1/mbf-1 (no b-frame, old scd???) no effect, all keyframes inserted at max. the bests y |

Yes, you are right. Forgot to change it. Done now!

Some new, minor things added:
MPEG-4 XviD Koepi 24062003-1 Encoder Guide - version 20030702: - B-frames settings: Suggestion not to go higher than 2 at Max B-frame settings. It is safe to use 2 for low and high bitrate solutions. - Chroma motion info added (Koepi): Use chroma (color) information to assist with motion detection - usual MPEG-1/2/4 encoding just uses luminance information for searching the motion.

Thanks Selur, but may be I did not express myself clearly. What I wanted to know was if the value in FPS in the notes refers to the one of the dvd2avi project made by Robot4Rip (which activates force film automatically if the movie is NTSC Film > 95%). Therefore, for instance, if the movie is NTSC Film < 95%, the value I get when I open the dvd2avi project in GK is 29.970. I´d like to know if that is the value to which the notes in Snowbeach´s guide refer: the value in FPS you get in Gordian Knot when you open the dvd2avi project made with Robot4Rip.

@loni_blues
It is not necessarily that frame rate (it is if you don't do anything else that changes the FPS) but the frame rate of the video during the encode to xvid. If you did not do a force film but do a IVTC then use the 23.976, if you do a bob then use a below i-frame distance of 30 (because the 29.970 frame rate goes to 59.94 when doing a bob) - it is the frame rate of the final video that is important. |

@snowbeach,
In your (excellent) guide, it says: Quote:

and: Quote:
So, may be doing both things is incompatible and it seems best not to set the FPS to 23.976 in the Frames tab in Gknot. See you, Loni Blues Last edited by loni_blues; 4th July 2003 at 01:24. |

First of all congratulations for this guide. As I'm don't have time to study this forum every day or test the best settings myself it helps a lot to find good settings.
There is only one thing that could be changed: You write that one should use h.263 above bitrates of 900kbps. I think that doesn't help much, because depending on the resolution you choose it could be more than 900kbps. You could be more precise by indicating the bits/pixel ratio. (even though it strongly depends on video you use (action film or a documentation..)) |
