AviSynth/CCE Frame Size Error

[spangle]

I am using AviSynth/CCE 2.67 to covert an AVI but keep getting the following error message:

"Frame size 748x56 not supported"

I realise 748 is larger than the supported frame size but I don't understand where 748 is coming from in the first place. My original AVI is 640x256 and it looks and plays perfectly. I'm using Fit2Disc to create the AviSynth script automatically from the source file (see below). The Fit2Disc resize is stated as 720 x 272 so I'm guessing that the script has somehow gone wrong as is causing the error

AviSource("c:\AVIFilename.avi")
ConvertToYUY2()
BicubicResize(720,272,0,0.6,11,0,618,256)
AddBorders(0,104,0,104)

I've used Fit2CD scripts many times without any problems and it still works fine for all other AVIs. I've also tried a simple script using instructions elsewhere on this site (see below) but get the same frame size error:

avisource("c:\AVIFilename.avi")
LanczosResize(720,288)
AddBorders(0,96,0,96)
ConvertToYUY2()

Can anybody with AviSynth knowledge please take a look at these scripts to see if there are any obvious reasons for the frame size error?

Thanks in advance.

The second script looks okay. Test your scripts using VirtualDub and see if the "File Information" returned by the program what you expected.

Ahaaa... thanks for the tip. When I tried to load into VirtualDub I got an "ACM could not suggest a compatible PCM format" error. It seems that this AVI has AC3 audio! I demuxed in VirtualDubMod and things now seem to be going according to plan.

If this is the problem then CCE sure gives a wacky error message for as audio related issue... but CCE is doing it's thing right now so I'll have to wait a few hours to be certain... but, so far so good!

Thanks again for the reply.

Well, for those interested I can confirm that after demuxing the AC3 and saving without audio, the AVI processed perfectly through CCE. I still don't understand why CCE gave a frame size error but at least it's resolved now. I've tested on a 2nd AVI with AC3 and found the same result.

Thanks agains to SLK001 for pointing me in the right direction.
