Aha. Good info.

Once again, 2 different issues in one statement. “DVDSP from self contained or Compressor from QT Reference.” Point being that with either, it makes no difference in quality which you use. Self contained or reference. So long as you don’t recompress the self contained. But that’s a no brainer.
I used to use reference movies quite a bit, but with drive space being inexpensive, they’re not worth the hassle. When backing up a DVD project, it’s nice to know that my QTs will work witout redigitizing my project.

If you need this all the time $40 isn’t much, but the simple old school way would be to view a black slug in the canvas window at 100% and turn on the title safe. Then press shift+apple+4 and lasso a screen shot of the area. Then simply place that resulting still in the middle of your widescreen canvas and use the screen composite mode to drop out the black. You could also take it into photoshop first and create a more standard alpha channel tiff or something that you just drag into the timeline. You could also create a matted clip that you drop in that mattes out the left and right while also showing title safe, etc.

Pretty sure you don’t have FCP 5.2.1 or am I that behind?

It seems to me you have 2 questions…
Which is better for compressing for DVD, DVD SP or Compressor?
and…
Is it better to export to Self Contained or Uncompressed?
The latter question is actually 2 questions in itself as well if you consider you can export directly to compressor from the timeline, or to a self contained movie and then drag into compressor. Either way it’s the same result, except you don’t have to tie up FCP if you use a separate file. Exporting ANY compressed clip to an uncompressed clip to use in Compressor is completely useless. In fact, although uncompressed, you are running it through yet one more step which could actually deteriorate, but very doubtful you’d ever notice. You can’t improve an image by uprezzing. There is no problem with self contained movies. I’d have to say they’re more reliable than QT reference movies, because the latter references render files and clips that could go away as you edit.
On the first question – I frequently let DVDSP render out the DVDs and haven’t had any problems with the quality. Usually corpoarate stuff. The biggest difference is in the audio. DVDSP can only create aiff audio which eats up lots of space AND requires a little umph to play back. Compressor lets you create the more standard dolby something or other. I forget.
The problem is that I’m frequently creating DVDs like a video. They aren’t just the final product. So they undergo many changes along with the video. If I keep exporting right over the old self contained files, I can simply open DVDSP and hit burn. Saves a couple steps. If I use compressor, I have to export a file, drag it to compressor, and then render over the old file, then open compressor and burn.
I’ve tried working with self contained QT until the final version of the DVD, but then you have to actually insert the audio tracks separately from the video tracks when making the switch from aiff to dolby.

So how can someone be running FCP 5 just fine on a dual 500mhz G4, but not a mac mini? Are you sure that’s not the specs for FCP Studio? Which would require a graphics card for MOTION? Because FCP doesn’t use the graphics card for squat.

There isn’t one. A 3rd party solution may exist, but what you’re generally seeing is done in camera. Possibly time lapse with extemely slow shutter speeds or leaving the shutter open altogether.

DV25 formats will comsume about 12 gigs per hour. Figure at 5:1 compression that uncompressed SD 8bit would consume 5 times that. Which would be 60gb per hour or more if 10bit. Sounds like you switched your settings.

If you still want a gradient, just another color, then color correct it and simply limit the color correction to that range of color. Shouldn’t be hard as the hand is very different in luma and hue from the background. Once you’ve isolated the background just change the hue/saturation to get the gold you were looking for.

Well, yes, if your sequence on V1 HAS alpha then that is retained. But if for example you have a video clip on V1 with motion effects, then black will be mixed in to the blank areas. No alpha. If you were to place the same on V2, and nothing on V1 and turn off V1, you’d get alpha.
Walter, I’m a little surprised!
