What is mpeg1 mux ?

[tchambers]

I have a downloaded clip that is in MPEG1 mux. I cannot load it into Vegas 6.0 without the converter. Does anyone know of a converter that will take it to a format that will load into Vegas?

Are you the same guy who was trying to edit Xvid in Vegas?
Anyway, as was mentioned in that thread, Vegas is not designed to edited compressed formats.
The best software for editing mpeg is mpg-vcr.
mpeg1 mux, means that it is mpeg 1 (as opposed to mpeg 2) that has an audio filed muxed with it, that is, the file contains both a video and an audio file. Many DVD authoring programs take elementary video and audio streams, that is, files that are only video or audio.

No I am not the guy but thanks for the info. All I want to do is take this clip and shorten it, loop it, and add it into an existing edited avi as a picture in picture. Vegas won't accept the clip without downloading a mpeg encoder or something like that. I noticed when I brought the clip into Pinnacle, it would load but would not play except for the sound. That seemed strange. So I had hoped to re-encode it to something that could be edited, at least cut and looped. Thanks

Do you have a version of Virtual Dub that accepts mpeg?
(If not go to tools and find it, because it is a great free program)
Open up your mpeg clip in virtual dub and then convert it to uncompressed AVI or DV AVI (if you have the latter as an option) and convert the audio to wav. The AVI file will be much bigger now, but Vegas will now take it. Do all your editing, and then render your final Vegas project into whatever format you wanted (although of course you cannot render the final project to mpeg without the Vegas plug-in) (You could always render to DV AVI in Vegas, and then convert to mpeg with one of many free mpeg encoders around.)

The first thing you need to do is find out what this file actually is. Use Gspot or similar.

(BTW, I noticed that there is a NEW version of Gspot due out soon!)

Let us know what you've got, and then more info could be given you at that point. Otherwise, we're just guessing.

This is what Gspot comes up with?

MPEG-1 System Stream << { 1 vid, 1 aud, 1 other }
Sys Bitrate: 1411 kb/s VBR

[Cornucopia]

My guess is that the VBR is what is making it difficult for Vegas (MPEG1 is rarely VBR).

Convert to an interim format. Use Virtualdub or VirtualdubMod or VirtualdubMPEG2 and save it as Losslessly compressed AVI (HuffYUV, Lagarith, etc) for video, with LPCM (Wave) audio.

This will work fine in Vegas.

That worked fine. Thanks for the help....
