Hi novadragon849,

You'll need to provide a little more info:

1. What's your source? What are you converting from? What format? Use GSpot on the source file and post a screen shot of the info here.
2. What are you converting to?
3. Describe, in reasonable detail, your process and settings used.
4. Take a screen print of the problematic output and post it here.

I am converting avi to avi but I am changing the TV size of the avi so that it fits onto my TV without cutting it out, but when I finished cinverting the file I converted has pieces missing or squares and I was asking how to fix that problem. I use a mpeg compression

Hi novadragon849,

You should know that "AVI" isn't really a format - it's more of a container for different types of formats. You can get uncompressed, DV, Divx, Xvid AVI. That's why I said to use GSpot.

You say you're doing "avi to avi", yet you then say you're using a mpeg compression. Which is it?

Also, VDubMod doesn't ouput to MPEG. It only takes them as an input.

I had this problem with Divx 5.2 .

I dont know what causes it, but I installed the latest version & seemed to solve it.

Actually, it can provided you have FFMPEG or YMPEG. However, it doesn't mux the audio in so you wind up with a m1v or m2v. But i think that's the only way.

I first opened up my avi format file onto virtualdubmod. I only wanted to resize the file so I added the resize filter and sorted out my new width and height. I then chose bicubic and added a frame around it, after that I chose the xvidmpeg4 compression. Then I saved it and it starts to do it resizing process. When it finishes I started watching it and I realised that squares that are not suppose to be there are appearing on the resized file. And on the main file (the avi file where I didn't resize it ) did not have those squares so I was wondering how to sort out this problem. Please help.

What compression rate did you use for the MPEG4 encoding? Pixelation is an indication that you are overcompressing.

[novadragon849]

Sorry I don't know how do you check it and how do I know if I'm overcompressing?

From VirtualDub(Mod):

Video -> Compression

Select XVID MPEG-4 codec

Press Configure button

Set Encoding Type to Single Pass

If the button below Encoding Type says Target Bitrate, press it to make it say Target Quantizer

Set the value to the right of Target Quantizer to 3. (Lower values will give better results but larger files, higher values give worse results but smaller files).

Save as AVI again.

Thats not correct. YMPEG has built in multiplexer and it can multiplex video and audio. However, you need to configure YMPEG in Audio compression settings in VirtualDubMod.

To configure Audio Compression in Virtualdubmod, select Stream List from Streams Menu, and Right click on Audio Stream. You will get a new context menu. Now, Select 'Full Processing Mode', and then Click on 'Compression'. You will get Audio Compression Dialog box. Select YMPEG Audio Codec.
