Frameserving and batch encoding

[kenmo]

I know how to batch encode avi's to Tmpgenc but what if I wanted to frameserve two or more seperate avi's to Tmpgenc (ie: one avi is Star Trek Voyager, another is X-Files). Each avi would be encoded as a seperate cvd comliant mpg file. Also I want to edit out commercials in each avi ?

I know I could save each editied avi as a two new avi's and then batch encode each edit avi but I find this takes more time.

Encoding an edited avi using the same settings for a cvd takes an hour and a bit more then encoding a frameserved avi on my system.

I haven't done it myself, but I've heard that you can do this by running more than one copy of VirtualDub at once and frameserving from each.

You can also learn to use avisynth, it doesn't require a running application to frameserve. I almost always use it.

Yes, you can run several copies of Vdub at once for frameserving and batch encoding, I've done as many as four.

My record is about 15....
There is also another way, using the "job" list of Vdub, but I don't remember the "how to" for it.
Anybody?

I did it more than once opening more istances of VDub.
But in one case I had problem in opening one of the .VDR file in TMPGEnc.
It said "File can't be open..ecc.". I had to stop serving the various sessions of VDub and leave only one.

Hope it helps

If I use avisynth I would NOT be able to edit out the tv advertisements

Funny, Trim() always worked just fine for me.

Yes but you would have to know exactly what frames contain advertisements. Still sounds like you would have to use Vdub...(at least to written down where tv ads begin & end)...

It is not neccessary to frameserve to tmpgenc for cutting the commercials from a raw capture. You can do it direct with the use of "source range" fuction of TMPGEnc. It is frame accurate and does excellent job. It even have a preview window to see what you do real time.
BUT, for long captures (>20min), frameserving is a must for various reasons. I always frameserve, even if I don't have to for true. I like to prevent things and frameserving helps me a lot for this!

But again, I prefer cut the adds with TMPGenc.
I grabb whole shows (those days, Jeremiah from SkyOne) with Virtualdub, using Mjpeg (fair quality for this source) and I end up with a 3-4GB file. With this filesize, I have to use vdub to frameserve to tmpegenc. There is no true reason to use filters or to resize, so it is only for the timestamping and the missing field things (vdub fix automaticly those things while frameserving). Then I load to tmpeg the fake avi from Vdub, I detect the field order (I use Hauppauge win tv, field order ain't always as it should be...), set the correct bitrate for a 42-45 episode (about 2050kb/s for a 80min CD) cut the commercials and all are OK.

There are times I do a TMPGenc batch encode and I run 5 - 6 Vdub frameserves the same time, using this way. When I return from work, all are ready to burn! (And I have to use VCR about 2 years that way!)

Right, I use the two together. VirtualDub for capture, finding frame numbers, and previewing the .avs file. Avisynth for actually doing all of the editing, especially when I want to do batch encoding.
