Thanks Alan - but I think I have to beg to differ... Encore just wouldn't let me import the file as an asset - I got a show-stopping error message - so putting it on the timeline never arose. I'd assumed that you could change the project pre-sets to the aspect ratio/number of pixels your incoming file would have, but couldn't find a place to do that. (There's something Encore does when you tell it you're starting a new project - I don't recall what it says it's doing, as I don't have a copy here, but the green progress indicator box comes up on screen - so I assume there's some way of changing what it does before you tell it you're starting a new project?) Or should I have changed the properties of the timeline before trying to import the asset?

I think it asks you if you want to start a PAL or NTSC project, then it says it's "configuring the transcode settings" or something like that, I don't think it asks if you want 16:9 or 4:3 though.

That sounds familiar.

I suspect your import issue is that the pixel dimensions are not amongst the recognised set. You hinted as much earlier.

You'll just have to trust me that the only mention of aspect ratio is a property on the timeline. At least it is on my copy of v1.5.1.

Trust you? I love you and would very much like to have your babies... :lol:

bgarthp: I need to take a closer look. I think you're right.

Alan: seriously, though... I can't believe that Encore can't deal with a standard 16:9 file. There must be a way... Unless, of course, given its dubious source, the .avi file is indeed in some way different.

I expect it's a DivX or Xvid file, so it won't be supported by Encore, and will have to be converted, If I ever want to put a divx/xvid on DVD I convert it straight to MPEG2 in TMPGEnc, then import to Encore, I've had no problemns doing that.

Ah - in my ignorance, I had always assumed/believed that .avi was .avi was .avi. But I infer from what you're saying that not all .avi's are created equal?

I think DivX, Xvid and some other MPEG4 codecs use the same extension, you can check what codec it is with G-spot. (I read this in another post on this forum, by MrLipring, I think)

AVI is a generic term used to describe the wrapper used to hold the video. What differentiates one "AVI" file from another is the codec used to encode the videe: DivX, Xvid, WMV etc.

Some codecs are so big they get their own fancy extension: WMV, MPEG etc. The extension is really a way of describing what the file is so that it can be associated with a specific piece of software. It's also an easy way of filtering files within "open" dialogue boxes... this is another area which cause confusion as some apps may give a different proprietary extension for a generic extension which will still be perfectly compatable with another piece of software. All you have to do is select "all files" to load it.

You could encode video with wmv and call it video.avi for example. Windows Media Player may complain that it's not the "correct"extension, but it will still play it! The only way of telling exactly how a video is encoded is by using something like gspot.

Gotcha - thanks Marc.

So now I've had a chance to look at the finished DVD. What I'm seeing is the faintest of 'stuttering' - movement is very, very slightly jerky, perhaps every second or so. I'm almost tempted to think it's missing a frame every so often, and on a regular basis. Could that be a function of how the original .avi file was encoded? Or have I screwed up a setting in Premiere?
