Premiere & MPEG2 - quick & dirty workaround
Had an interesting twist lately. I accidentally deleted a file before I should have. I had a preview file that Encore generated. (MPG2 I believe - "M2V") which I used to finish the project. I know you need special tools to edit MPEGs on account the GoP - snipping one in a non-MPEG2 saavy tool causes all sorts of oddness. (try it if you haven't - it's amusing when you're not under a tight deadline) So, here's the part I thought was kinda neat: The file was one, long, continuous sequence of an hour long music gig. The artist wanted several songs plucked out and made into online, streaming versions. (WM9, 128k files) Instead of chopping the M2V, a new video track was added on top (in Premiere) and a 5 second chunk of black video put at the start and end of the desired segment. The black video had a "fade" transition applied so it *appeared* the underlaying clip was fading in and out - but without having to apply any edits/fades/cuts to the MPG clip. I figured this wouldn't work - but it did. Rendered out fine, no MPG GoP issues. This may not be news to anyone - but if it helps anyone with their own projects, I wanted to share the experience. Knowing this would have saved me a lot of trouble in the past on projects involving legacy source material. Cheers! Chris C.J.Patten wrote:

I think all you are saying is that you put an MPG clip on the timeline and rendered it out to AVI again. Anyway, that is what I would do, if I didn't have the source tape any more. Then you can edit the AVI as desired. GAry Eickmeier Hey Gary!
Sure, rendering the entire sequence to AVI would have been required if it needed editing in it's entirely. As it was, I needed two things: 1) the entire sequence for the DVD (where I used the M2V file as-is, no editing or rendering) 2) bits & pieces with fades in and out, in a format for web-streaming. (about 15% of the total timeline) I mentioned this particular case because I *thought* I was going to have to do exactly what you suggest - rendering the entire AVI. Being able to overlay the fades probably saved a few hours of rendering. Maybe it's not news to anyone but me, but it was useful for my purposes - perhaps someone else can save some time if they find themselves in a similar situation. :) Cheers, Chris Show quoteHide quote "Gary Eickmeier" <geick***@tampabay.rr.com> wrote in message news:cR6fe.3691$VH2.2256@tornado.tampabay.rr.com... > I'm not sure exactly what the fades have to do with it rendering out fine. > I think all you are saying is that you put an MPG clip on the timeline and > rendered it out to AVI again.

Are you simply putting the work area over only the part you want to render, then the next one, and so on?? That would complete the picture... Gary Eickmeier That's exactly what's being done... just rendering the work area.
Don't usually miss describing those little details - good catch. C.
