Good for you, that means you must never have tried using MPEG-4-based (i.e. DivX, XviD, etc.) AVIs in Premiere.

That's funny. I've used DivX AVIs in Premiere before, and it never gave me problems. Is that just an on-again/off-again type of problem? Or does it depend on the version of Premiere?

Honestly couldn't say. I've only ever used DivX clips before in Premiere 5.1, and while I don't remember it crashing significantly more than usual, I do remember all the ugly-lookin' green crap that showed up in the frames every time your clip started on something other than a keyframe (or something like that). It was just a mess, really.

Ok, the version thing must be it then. I'm using Premiere 6.5. And I didn't get the nasty green stuff either.

But is it frame-accurate? One of the main reasons people around here always give for not using MPEG-4-based footage in Premiere is that, with the way Premiere processes it, it ends up not being frame-accurate. I don't remember the technical details.

... that's one of the most worthless answers I've ever heard. That's like saying Cars work well on roads.

I'm currently imagining Justin as Gabe from Penny Arcade, and I'm chuckling.

I'm not quite sure what you mean by 'frame-accurate.' If it's something that screws up the way the AVI plays after it's exported, and the way other programs (like TMPGEnc) handle it, the file I made didn't have any of those problems.

He means, that the frames aren't in the exact place you put them, and can cause your video/music to be out of sync.

It seems as though Premiere accesses AVI files through DirectShow and not Video for Windows. If that's the case, then it could very well make access not frame-accurate. However, some DirectShow decoders can be frame-accurate like 3ivx directshow filter...

Something along those lines... I am not sure though, because Premiere may actually use VfW and not Dshow, but I am not sure...

What does it matter? Using DVD Rips and AVISynth is still the best way to do it. Although you get the odd discrepancy and error with that too... like my AVISynth 2.52 refuses to auto-load MPEG2DEC3 even though its in the right directory... slightly confusing... but yeh, its still better, both quality wise and frame-accuracy wise than any AVI kind of AVI File editing (with the exception of huffyuv and PicMJPEG [for the mjpeg/AVS switchout option] of course, at least where frame accuracy is concerned)
so why bother debating exactly what Premiere uses? I always thought Premiere used DirectShow as well.
