Frame size 820x56 is not supported using avisynth 2.5 but 2.07 works HELP!

[Roveer]

I just built an Dual Xeon 2.8ghz system and work with CCE. I'm trying to wring out every last bit of performance and someone suggested that I try Avisynth 2.5. I had been using AVISynth 2.07 with the basic 3 line script (no filters) right into CCE and I was getting great performance. So I downloaded AVISYNTH 2.5, removed the 2.07 and installed 2.5

First noticed that the icon next to the AVS file dissapeared then when I try to load the AVS script into CCE I get the following error:

Frame size 820x56 is not supported. Supported frame size is up to 720x576.

Well I'm not cropping or making any changes to the material that works just fine with AVISYNTH 2.07.

Any ideas?

The reason you're probably getting that resolution is because AVISynth is outputting an Error Message.
Open the AVS file in VirtualDub and look at the video screen or look at the popup message displayed to see what the problem is.

You must use multiples of 16 for width and height Roveer.
AVISynth 2.07 does not seem to have this problem.

Do what ErMac suggests, and also post the script file. See troubleshooting on avisynth.org.

Here is the script that I'm using. The input is 720x480 and it works just fine if I use AVISYNTH 2.07. I was told that 2.5 might give me much better speeds, but not if all I get is the frame size error message.

LoadPlugin("C:\DVD\MPEG2DEC\mpeg2dec.dll")
mpeg2source("D:\MOVIE.D2V")
ResampleAudio(44100)

Any ideas?

Did you use MarcFD's mpeg2dec3 with yv12 colorspace output capability?
Because from your script it seems that you used the old mpeg2dec, which works only in yuv2 colorspace, and avisynth 2.5 requires yv12 by default.

As ErMaC said, avisynth is probably outputting an error message to CCE. Make sure that you've updated all your avisynth filters (in your case, mpeg2dec). It'd probably also be a good idea to check out the Avisynth FAQ (linked off the sticky thread) or the other Avisynth2.5 threads to see what exactly changing from 2.0x to 2.5 entails. I think I remember that there being some issues with avisynth 2.5 and CCE (or was it only YV12?), but they came up with a workaround. A search for avisynth 2.5 and CCE in the avisynth forum should find the thread.

Hope this helps,

Always check you script in Virtual Dub (mod) for errors before encoding.

I think the problem is that the Resampleaudio() call has been changed. In the old AviSynth it always added a silent track to the video if no audio was found, and now it doesn't. And if I recall correctly CCE requires an audio track to go with the video. The avisynth docs probably still tells you that adding Resampleaudio() will remedy this. Since it doesn't it's probably time to suggest a new solution. Quite frankly: is there a way of accomplishing this today?

[ffroms]

sh0dan have some script (function) and AddAudio() but it didn't work for me so I've created 1 sec. of silent audio (WAV) and I use AudioDub to fool CCE.
@Roveer - Try to put ConvertToYUY2 at end of script 'couse CCE don't work with YV12.

i am using the latest avisynth 2.5 with mpeg2dec3 and just use killaudio() command and its working ok.

[ffroms]

If you are using CCE SP 2.5 it wont work 'couse CCE needs audio+video or it will crash so that's why I use workaround and ofcourse it needs ConvertToYUY2 at end of script.

This is not true. AviSynth2.5 can work as well as 2.07 with YUY2. It's just that afaik only mpeg2dec3.dll works with avisynth2.5 and outputs YV12 by default. If he used a YUY2 mpeg2dec.dll that works with 2.5 he's fine, 'cause CCE only eats YUY2. The trouble therefore probably is, as many have posted, the change in ResampleAudio().

[Roveer]

Working now... Using killaudio()& ConvertToYUY2 and all seems well.

BTW, CCE speeds between 3.5-4.0 on my Dual Xeon 2.8ghz system. I'm really happy. Can encode a whole DVD (VAF & 3pass) in 1 hour 30 minutes. On my 1.6ghz machine it's taking 1.5hrs just to do the VAF and 6-7 more hours for the 3 pass. This is just the type of speed increase I was looking for. Yahoo...
