Export to dv-format

tuxfan wrote on 2/1/2003, 3:00 PM
Till now I use the demo of VV only, but I am very impressed and have ordered it already. I have a Celeron 800 (Linux only) in another room for capturing with kino via Ethernet (Samba Server). This works fine, but I would like to postprocess the file with transcode, which was rendered with VV on a Celeron 1300, because the Samba-Server (Celereon 1000) is bored the whole day and could do encoding. I know it is a slow machine, but even capturing and encoding works at the same time with a 5400-drive via Ethernet (big surprise). Unfortunately a dv-format-file works best here with transcode. With all avi-files I have the 4:42-problem. So, is it possible to create a dv-file with VV?

I don't think I understand the situation. You have 3 computers you are working with, right?

Celeron 800 (with Linux)
Celeron 1000
Celeron 1300

Your editing on the 1300 and wanting to output the file to DV format so you can copy it to one of the other comptuers to do what with? And what is this transcode you keep talking about?

Correct me wherever I'm misunderstanding things.

Yes, I have 3 pcs and a few more for other things like a firewall, proxyserver, a.s.o., which is not important here.

Celeron 800 is for capturing only
Celeron 1300 is for video-editing and rendering
and the Celeron 1000 is a Samba-fileserver for the video-files. No, I don't copy the files, I use netvolumes. A Samba-Fileserver is a Linux Server, which - simply said - makes Win think there is a Win-fileserver. In other words I would like to use VV with the 1300 and store the files on the 1000 via 100Mbit Ethernet. Note: Till now I could not save files, since I have the demo only. I am asking in advance to speed up the start, when VV arrives.

Transcode is - simple said - something like tmpgenc. For more informations see http://www.theorie.physik.uni-goettingen.de/~ostreich/transcode/ (in English)

The advantage of this combination is:
I can work with the client all the time, while the Samba-fileserver encodes a SVCD. If I capture at the same time with the 800 it works without dropped frames to write on the same harddisk of the Samba-Server via Ethernet. Even I can capture with the 800 using Linux to a file on the Sambaserver and start a few minutes later encoding the *same* capture-file with transcode.

My problem now is - as mentioned - that I need a rendered file from VV in dv(raw)-format, since *I* have problems with avi-files and transcode. Is this possible?

I'm not sure I'm going to be the one that can answer your question with absolute certainty. But, here's what I think. If I'm wrong, maybe someone who knows for sure can correct me.

First let me ask another question in case my ignorance completely cancels out everything below. In your original post, what did you mean that with AVI files you have the 4:42 problem?

After looking at Transcode's web page it seems to me that there shouldn't be a problem processing DV encoded AVI files. The Transcode flow chart shows MPEG, DV, RAW, DIVX, and MJPEG compression codecs under the AVI container. I can't tell for certain what Transcode is refering to by RAW, but if they are simply meaning the absence of any compression then Vegas does offer the ability to render to an uncompressed AVI.

If you are generaly having trouble with all AVI files then perhaps there is a problem with Transcode's codecs. From what I can see there shouldn't be a problem. In addition, as far as I know, Vegas outputs industry standard DV formating. But, there is a check box on the video tab in the options for the DV codec that says:

[]Create an OpenDML (AVI version 2.0) compatible file.

which was checked by default on my copy. I'm not sure what the file turns into if it is not checked.

I guess my suggestion is this...

Read the last paragraph on the "About" page on the Transcode web site.
http://www.theorie.physik.uni-goettingen.de/~ostreich/transcode/html/intro.html#about

Then check to make sure you have the latest version with the latest codecs.

P.S.
After writing all of this I got to wondering if when you mentioned 4:42 in your original post if you were trying to say you were getting recompression artifacts from the 4:2:2 DV compression. If that's the case then, I guess, an uncompressed AVI is all you were wanting to know about, which Vegas will do.

Whew! That's a lot of stuff to type.

Thanks! I see I have to try the different formats and options.

I get *excellent* quality from different avi-files with transcode, but unfortunately encoding stops after 4:42 everytime. Since nobody else in the transcode-mailinglist knows this problem, there must be something wrong within my system. Maybe it is bug, which was solved in the newest version 0.6.3, while I use 0.6.2. But I am happy that 0.6.2 works as it does. It is hard job to compile transcode. So I use transcode as a compiled package from http://packman.links2linux.de/index.php4?action=150&vn=2 and there is no newer one.

I recall a similar 4:42 issue a while back. The short answer is in Options => Preferences... => General, make sure that "Strictly conform to AVI2 specification" is not checked (unchecked is the default).

Hope this helps!

Oh. That's what you meant by 4:42. After 4 minutes and 42 seconds transcode stops. That's interesting. Let me think on this a little while.

By the way. Were you saying that version 0.6.3 actually fixed that problem or are you hoping it will?

It is not checked here

I hope my problem is solved with transcode 0.6.3 and I read that a compiled package will be released for Suse soon.

In the meantime I rendered with different settings, but no chance to encode more than 1GB with transcode. Is it possible to write the stream, which is sent to the camera to a file? I would like to try this. IMO this should be similar to the dv-format, which works with transcode.

BTW Vegas is a great programm, I use it a few days only and I am very happy that I bought it.
