Possible Avisyth Problem

[trash]

I have the following error message when I pulled my avs file into VirtualDub to verify if FitCD correctly wrote my avs file.
Error message :
Asynth open failure
No Compatible ACM codec to decode 0X2000 audio stream to PCM. (C:\Documents and Settings\file.avs,line 2)

My avs command
AVISource("C:\Documents and Settings\file.avi")
LanczosResize(688,336,0,1,624,334)
AddBorders(16,72,16,72)
#Trim(0,117764).FadeOut(150)
ConvertToYUY2() # For VirtualDub or CCE


My original file is 624X336. Audio is ac3(0X2000) Dolby Labs. Stats: 2 compatible codec installed. This is the info from G spot

Please let me know what I should do? Thanks for your help in advance

AVISource("C:\Documents and Settings\file.avi",false)

From the resolution you are going for DVD, so you don't want to re-encode the audio anyway. Just extract it and reuse it.

GSpot is probably reporting dshow decoders. AVISource requires ACM decompressors.

If I cannot play avs file in VirtualDub does it mean that there is an error in the coding besides false statement? Should it be a concern? Cos next stage I am going to use HC encoder so would it give me an error message cos of this avs file

If you can open it in VDub and scroll around without getting an error message or having it crash, then you're OK for encoding with HC Encoder.

By the way, I believe that the HC Encoder accepts YV12 input, so either leave off the ConvertToYUY2 line (which is for CCE after all), or add ConvertToYV12() at the end if the source isn't already YV12.

And I guess you know you're adding 2 blocks overscan on purpose. It's nothing I would do, but to each his own.

I am not even sure what block overscan is . It was automatically on 2 so I did not change it. Do I need to?

People should really learn about the tools they are using, not just plug numbers in blindly.

Overscan is the area of the image covered by the surrounds of your TV case. How much is covered varies from TV to TV. Usually this is not a problem, as all TV shows have some of the image covered. However some downloaded material, generally anime, have had subtitles added too close to the edge of the image by people with no real idea what they are doing. In this case, the subs fall into the overscan area and cannot be read. To fix this problem, the video can be resized down, and black borders added to push the subs back into the visible area. FitCD measures how much by blocks of pixels. In your case, 2 blocks.

Read the readme file that came with FitCD for a pretty good run down of what everything means.

Thanks for the detail explanation. I will go into the file to read it now.
