Hi,
I'm trying to compress a short AVI after I took the logo away(LogoAway 4.01).
I choose for the Xvid MPEG-4 Codec and afther that I click 'save as Avi'.
But I'm receiving an error: "cannot start video compression: an unknown error
occured(may be corrupt data). (errorcode -100)
I've got K-Lite Mega Codec Pack installed.
Do I still miss a codec?
Thanks!

Usual reasons include
Width not a multiple of 4
Height not a multiple of 4
Fps too high for the selected profile in the codec

I'm sorry but I don't have a clue where you're talking about...
I'm not that familiar with VirtualDub or compressing files.
Maybe you could be more specific?
What exactly is wrong? |

Check the video source
File menu->File Information
You'll see the width and height and fps of the video there
To recompress, most codecs like xvid need the width and height to be a multiple of 4
If it's not then it won't compress it and you'll get an error
If the video doesn't have a height or width that is a multiple of 4, then you can either
1)add a null filter and crop off the excess pixels to get the right size
or
2)add a resize filter and set the width/height to the nearest multiple of 4
The help file is useful, and so is the search button on the forum
Youtube also has 'walkthrough' videos

Thanks for the information, it was much more clear for me.
It worked by using the resize filter. But maybe the quality could be a bit better.
So I want to do it all over again with VirtualDub.
The sourcefile of this small video is a flv.
I used Total Video Converter to convert it to MPEG4V2 Avi normal quality.
XVID Normal quality didn't work because of the same problem you were talking about before.
My question is: to what should I convert this flv-file to use it in VirtualD?
What is the best quality?
Maybe I shouldn't use Total Video Converter? |
