Virtualdub and MPEG2

[Delta2]

Hi,

I have - VirtualDubMod and VirtualDub, both with MPEG2 support

But there is no option to save or recompress back to MPEG2

i.e.

I want to add some filters and then save/recompress in the same format - mpeg2, there is only Save as AVI option

is this not possible ?

Not possible. You are looking at the wrong tool for that. What you need for encoding to MPEG-2 is an MPEG-2 encoder like CCE, HC, or QuEnc. Use search to get more info on those.

well then, how can I resize a mpeg2 source and cropping in order to convert to AVI/DIVX ????

Video Size Calculator give this solution for a 16:9 PAL source :

Solution (adjust source width)
clip or pad source size to 704x558 and resize to 640x464

How can this be done using FFMPEG or other command line tool ?

Ewww..how about using the Search button for a change?

Or look here - http://www.doom9.org/divx-encoding.htm

What is actually your question?
As I read this, you first look for a took that can convert MPEG2 streams, second you look for a tool to convert to an avi container.
So what is actually your question?

If youre are looking to do a filtering on a MPEG2 and convert back to MPEG2, consider using AVISynth, and as unskinnyboy said read instead under the AVISynth forum they will actually could help you a lot, and go find yourself a MPEG2 converter CCE or QuEnc.

I'm doing a vb.net project for my personal use. Therefore at this time I can rip the right streams from DVD and multiplex audio and video in a single MPEG-2 STREAM....no matter if it is AC3 AUDIO, DTS, in chinese or spanish or french...I just select the right ones..all works OK....

The problem is that some DVD-PAL sources are Anamorphic, and in order to encode to AVI I need to cropping the top and bottom X and Y offsets (letterboxes)...BECAUSE..if I don't do this...the resulting AVI will be small in height..there will be loss of quality because it is impossible to encode using all frame size available....imagine a target AVI with 640x272....because of the anamorphic source the AVI height will not be a full 272...

I'm using FFMPEG to encode to AVI...very fast...I have all jobs done in 2 hours +/-

BUT, as I said...I have this problem

can you understand now ?

As I already said, youre better off with AviSynth, this scripting system actually can do the job. resize, crop borders, add borders and much much more.
There is actually an avs2avi converter

Actually I've only done recording video and convert it to DVD. which also works nice with AVISynth.
The advantage I've got from doing this is that I don't have to convert AVI to AVI via virtualdub and let virtualdub do the resizing or some other thing, and then convert to Mpeg2.
