You didn’t by any chance trim your source clip by a few frames and then run the autotrace for the super-tight junk matte?
I’ve seen it to where it will trace the footage from the beginning of the source rather than the current in point of your source footage…causing the autotrace matte to be off by the “trimmed” number of frames.Erik

Sorry…that was a response to a different post…

I think the majority of problems between AE and QT 7.4 has been during rendering. Most commonly rendering stops and errors after something like 10 mins of rendering.
Does the same file open in QT by itself?…outside of AE?

You’ll want to limit any further compressing..so I wouldn’t recommend dumping to tape and recapturing…
How long is your actual video?
The problem with presets is that they aren’t always the best choice in every situation.
To squeeze the best quality out of what you have to work with, you need to tinker with the compression settings.
If your video is less then 30mins, go all out with 7mb/s CBR encoding. If you have longer video 1h+, I’d recommend finding a bitrate calculator online to get a ballpark estimate of what VBR bitrate to aim for, not exceeding 7mb/s (for compatibility).
Tricky thing with DVD is that it has a finite amount of space on it. The only variable in the encoding you have to work with is how much compression is used for the video (audio has set bitrates) in order to make it fit. There are always tradeoffs. Cramming a two hour video on a single layer DVD might require some brutal compression and won’t be anywhere near the quality of your original source…Erik

Can you give us a hint?
What happens? Any error messages? Where did these QT files come from? What CODEC are they using? Will that play in the QT player?Erik

image sequences are great for progressive sequences since by very nature they are progressive. In some cases using lossless image formats like PNG can actually result in a smaller overall size. Image sequences are also universally readable and cross platform. So if you need to hand off an effect to someone else to incorporate into a larger overall piece (like a film) and they are finishing with a proprietary or high-end system (which might be on a linux system or something else that can’t read a QT), they may request an image sequence.
If you have a AE project that is a little complex or prone to odd crashes during rendering, exporting to an image sequence can save some time, since every frame up until the crash is still usable allowing you to pick up exporting from a point after the crash. The same can’t be said for exporting a QT movie since in most cases if the render crashes the file is in an unusable state..forcing you to begin rendering the whole thing again.
The drawback is that instead of having one large self-contained file, you now have a folder many many files in it, one file for every frame..lose one and everything is a little out of whack since you’ve skipped a frame. Also, some compression software might not know how to properly deal with image sequences (importing a single file rather than the entire sequence).Erik

It probably can’t. A reference file refers (hence the name) to existing media on the drive. Since AE is creating this media by rendering a comp, it is essentially creating a self contained file anyway. Reference files are great for exporting from an NLE since you have already captured a lot of content from tape, created little bits of media (like transitions and small effects) it avoids possibly re-compressing media again, is created very fast and creates a smaller file that instructs other apps where all the little pieces of media are. Because of their very nature, reference files are only useful if they are being used on the same system they were created on. If you were to copy a reference file to another system it would error since it can’t find the media.
Out of AE export lossless Quicktimes (i.e. QT animation, Sheer, etc…) or image sequences.Erik

I tried this with Procoder 3 as well. It wouldn’t let me create a WMV with a size greater than 2000 pixels wide.

Maybe we need more info on how this comp is set up and what camera movement is being made.
Panning from left to right by keyframing the point of interest from the left side of the frame to the right (keeping the position of the camera the same), doesn’t appear to create any parallax, but then the logo isn’t centered in the frame.
Orbiting the camera around the logo, say by creating a null parenting the camera to the null and keyframing the orientation of the null’s Y axis, does create parallax, but does keep the logo centered
Trucking the camera from left to right also creates parallax, but doesn’t keep the logo centered in the frame.Erik
