Avisnth and CCE usage inquiry

[Josip1]

HI,

I've been using Avisynth v2.07 in conjunction with CCE 2.66.01.07 for quite a long time now. I'm always encoding PAL movies. My avs file consists of:

Line 1 "LoadPlugin("C:\Program Files\Tools\DVD\AviSynth\plugins\mpeg2dec3.dll")"
Line 2 "mpeg2source("C:\ArmageddonD1_25\VIDEO_TS\z.d2v",iDCT=2,CPU=0)"

Ive never had any problems encoding movies till I came across "Independence Day Extended Edition" Encoding the movie was a normal process. When the movie was compiled and played on my set top dvd player the movie jitters when there is motion. Like there is ghosting but in a different way. It looks fine when there's no motion. i wasnt to trouble by it, I used DVDShrink to encode the movie. It didnt have any problem with it. I didnt realy think much of it untill the other week when i tried encoding StarTrek TNG Season 7. Below are the details take from BitRate Viewer v1.5.045 if that helps. There was a thread that was in Avisynth Usage section in this forum topic was "pal problem" this guy had the same problem. He stated that his bitrate viewer said that it was interlace but suspeced that it was progressive. I'm not too knowledgeable in that area. So would it fix the problem if i chose progressive in CCE instead of Interlace? So i have had to resort to using DVDShrink v3 b5 to encode StarTrek TNG.

The next problem is that I want to start using Avisynth v2.52.2 and a codec that will give me the best quility. It doesnt bother me how long it takes to re-encode the movie file. I hate these single click encoding programs i want something that gives me the best quality.
I've been trying to read a whole heap of threads in forums and searching in google a "How to" for setting up and using avisynth with cce to get the best quility and what codec to use with avisynth but ive been getting no luck.

If anyone can help me out any point me to the right direction, it would be greatly appreciated. Hope I haven't left any information out that would be helpfull.

Try changing the Field top first to NO. This is covered in the CCE FAQ in the CCE forum.

The jittering is very likely because "Upper Field First" setting is wrong.

When using AviSynth 2.5.x be sure to end your script with

ConvertToYUY2(interlaced=true)

If your material is interlaced - otherwise "interlaced=false".

I did a test encode with Upper Field First disabled. It fixed the problem.:D See I never thought it had to do with that option as BitRateViewer was telling me that the input video file was TopField First. Therefore I was leaving Upper Field First enabled.

I read the CCE FAQ as you stated and it explained how it all works.


What would the advantages of using Avisynth 2.5.2 compared to Avisynth 2.08 as CCE does not have native support for YV12 and having
to use ConvertToYUY2 in the script.:confused:


digitalman and sh0dan, thanks dudes for your help.
Its greatly appreciated :D
