mpeg2 to ??what??? and back to mpeg2

[SiG_ZA]

I have a large mpeg2 file that I would like to edit (ie. cut out pieces, crop and so on).

This can all easily be done using VirtualDub MPEG2.

Problem is, I want to save it into a format with out too much loss, but that does not use lots of harddrive space, and then re-encode it back to mpeg2 using TMPGEnc Plus.

What codec should I use and where can I find it? VirtualDub MPEG2 has a very limited selection and most are slow or take up too much space.

Or is there an easier way to do this?

VideoReDo is an excellent MPEG editor and will save your finished work as MPEG, so need to re-encode.

Can VideoRedo crop only certain sections of the video and then pad it?
There are certain parts of the video where I need to crop off the bottom few lines, but then pad these frames so that the video remains 720x576.

I downloaded the Trial.
No cropping facilities.

So back to the original encoding question!

tried frameserve? www.videohelp.com/virtualdubframeserve

but you can crop with tmpgenc.

You can't change the structure of the video and not re-encode, so follow baldrick's advice and frameserve.

Only the whole movie, not parts of it - AFAIK.

*cough*, hence my encoding question.

With the frameserver can you edit and modify Your video in virtualdub and then "frameserve" the video directly to any encoder wihout creating a temporarily AVI file.

Sounds interesting, in 10 words or less, what does this mean?
I am guessing that the encoder app some how catches the output from VirtualDub?

The frameserving application, in this case virtualdub, creates a signpost file. For all intents and purposes it looks like a video file to the client application (let's say, tmpgenc). When you load the signpost file into tmpgenc, virtualdub sends frames on request to tmpgenc. The beauty of this is that the data being sent through the frameserver is uncompressed, so there is no intermediate compression. virtually no HDD space is required as the only thing written is the signpost file.

Avisynth is also a frameserver, however it is script based, and the avs script replaces the signpost file that vitrualdub uses. The script also describes the filters and edits you are going to perform on the source. It is more complex than virtualdub, but generally much faster, especially when doing lots of processing.

You can also get a frameserver for most of the major NLEs - vegs and premiere amongst them, so you can edit and filter in vegas, then frameserve out to, say, CCE without an intermediate render.

Where has this been hiding?
Works brilliant!

Very much thankyous.
