VT3 .avi file does not load into LIGOS MPeg Encoder

[wtdedula]

Hello All;
I tried to load a .avi file into tle LIGOS LSX-MPEG Encoder that I created with the T3 using "Save as" and .avi and I get an error that it will not accept the audio format (It requires .pcm).

How do I get the audio file of a T3 .avi file created using "Save As" in .pcm format or how do I get the audio and video to load into the LIGOS encoder ?

The Video loaded and I was able to create the slide show BUT LIGOS disabled the audio so it did not get encoded with the video.

Can anyone help or offer suggestions ? What good is that .avi wrapper or whatever you call it if it will not import into all progams that will accept .avi files ... like LIGOS ?

The VT[3] avi wrapper creates a compressed audio file, which some applications may not like. The work-around is to go back to the project and create an audio-only render of uncompressed wav. Save it with the same name as your avi file in the same folder. Ligos should accept that.

Paul;
This DOES NOT work. I saved the .avi file as "inv_flt.avi" and then I rendered a uncomperssed .wav file of the same project out at "inv_flt.wav". I stored both on the root directory of drive D:.

When I loaded LIGOS MPEG encoder, it only gave me an option to enter a .avi file - no where could I specify a .wav file unless this capability is in a newer version that I don't have yet.

When I run the program, it will only convert the video. It disables the audio. In my opinion, the .avi wrapper function of T3 isn't any good if it won't create a file compatible with DVD production since I'm sure this is how many people will use it.

I spent all night literally rendering a Cinepack version of the .avi file but LIGOS complained and exited prematurely when it couldn't read a bit of data from the file.

Has anyone else tried to import a .avi file created with the new T3 into the LIGOS MPEG encoder ? If so, how ... or isn't is possible ? I need to create a 720 X 480 MPEG file ... otherwise, I would use TMPEGEnc. But TMPEGEnc only creates a 320 X 240 MPEG-1 file which doesn't meet my requirements.

Doesn't Ligos have the 2GB file size limit? How are you working around this? Are your VT[3] files smaller than 2GB?

I bought Ligos and then discovered the file size limit. They suggested using Virtual Dub in proxy mode to get around this limitation in their program. Waste of time and money.
I need to create a 720 X 480 MPEG file ... otherwise, I would use TMPEGEnc.
You should take another look at TMPEGenc. It does do 720 x 480 MPeg-2, this feature was added in 2001. In the project wizard select DVD.

The download version lets you try it for free for 14 days.

Gordon;
Thanks for your suggestions. I am fully aware that TMPEMPEnc will create a 720 X 480 MPEG-@ file. HOWEVER, I require MPEG-1 (NOT MPEG-2). I require a file format that will be the most compatible with every computer without downloading any CODEC's and it will also be compact so a 20-minute video will fit on a CD.

Mny suggestions how to create a MPEG-1, 720 X 480 file from a VT-3 (VT-Edit) project ?

Sorry for the misunderstanding Tim.

I have not tried to create a 720 x 480 VideoCD.

As I pointed out in the other thread, for MPEG-1 you want 352X240.

MPEG-1 720X480 is NOT a legal format, period.

If you're looking for something that will look great on CD-ROM played on computer, try MPEG-1 352X240 CBR 1800kb/s for the video and MPEG-1 Layer 2 192kb/s for the audio.

Eugene,
Read in the box the stream type is set to MPEG2.

OK Eugene at ScorpioProd;
I understand that the specs. for MPEG-1 is 320 X 240.

I was, however able to create a MPEG-1 720 X 480 production using a 720 X 480 .avi file using the LIGOS LSX-MPEG encoder but for some reason, the software always gets an error (and aborts) when I try to convert a long file that was created in VT-Edit. In my opinion, the file looked great, and performed well at 720 X 480 if Played from the Hard Drive. The onl rationale for using 720X480 rather than 320X240 is the larger size.

I did create a 320X240 MPEG-1 file this morning with audio and it looks OK so I may just go this route using TMPEGEnc.

[ScorpioProd]

Yeah, except Tim didn't post that box, Bob. ;)

Tim, what data rate did you use for your 720X480 MPEG-1 in the other encoder?

BTW, it's not 320X240, it's 352X240. It's based on half of 704, which is basically the active pixels across in 720. If you actually use 320, you'll force scaling instead of a halving of the resolution, resulting in lower quality.

The avi wraper in T3 also has audio that does not work
The best qual and speed con from renderin out the project
and then do encode with the rtv plugin for tmpeg

[ScorpioProd]

The avi wrapper is not the proper way to use TMPGEnc with the VT[3].

The proper way is the dedicated third-party support plug-in that comes with VT[3] that will install into the TMPGEnc directory.

Then you use normal VT-Edit projects dropped in, NOT AVI wrapped projects.

And I used to think that rendering out was quicker, but I've done a lot of tests on it and using the plug-in is quicker than a render plus an encode. It doesn't always feel like it is, but it is.

(Note that the dedicated plug-in is quicker than the AVI wrapper would be, too.)

[Pete Draves]

we found that the plugin is better than the avi wraper.
tmpeg works much faster even considering the render out time.

so far i havent found anything that will accepr the wraper.

just thought i would try it

btw tempeg blows liogos out of the water for speed and quality.
