Two Questions
Hi I have two questions:
The first one is how come when you export from fcp or compressor the final project sometimes has what i can describe as a sort of ripple that travels up/down the image. Like a skinny line of some sort? I honestly have been using fcp for years and don’t know why that happens. I see it in other peoples work online too sometimes.
My other question is:
I have 2 hours of video in apple pro res422 that i’ve sent to compressor. I am exporting it in both blu ray and for standard dvd. The blu ray export took about 21 hours. Now I expected the standard def export to take awhile but not 19hours. It’s been going since 3:45am and it looks as thought about 8 hours are remaining! The finished file is expected to be 4gig while in blu ray it was about 21 gigs. So my question is: why would the export times be so similar when the file sizes are so drastically different? It’s really horrible because this job I want to submit has literally had me exporting solid for the past week!I cleared out my preferences folder of compressor last night. I have compressor version 3.5.3 I have a macbook pro with 4gigs of ram.

You’re on a laptop. Compression times for HD are slow on many desktops.
I have 2 hours of video in apple pro res422 that i’ve sent to compressor. I assume this is HD material?
You’ll have to wait it out.

Not sure about the ripple, but Chris is right. 2 hours of HD material compressed for BluRay…and for SD DVD…will take a while. BluRay encoding takes a while normally. On my 3.0 Octocore MacPro it took 10 hours. OH, until I enabled QMASTER that allows me to use all of my processors to work on this. Then it took 5 hours.
A laptop can’t take advantage of QMASTER…so it will take longer. What you gain in portablity you sacrifice in speed.

If you look at the video on a computer screen you’ll often see the line running through the video. It’s caused by the difference in refresh rate of the computer screen in relation to the the frame rate of the video. It’s more apparent on some content than others. I don’t know anything you can do about it.
All the best,

okay thanks that makes sense. so I guess then the same file wouldn’t do that on a television. I’ll have to check that out.

yes. and a lot of colour correction filters as well.
I’m so scared to find a glitch in any of these exports when they’re done.. imagine starting again!

The older your MacBook Pro, the slower your render times. Bottom line.
Typically a one hour movie on our Mac Pro’s take approx 3 hours to render the BluRay file. So a two hour movie would take about 6 hours. So your laptop taking as long as it is, not really surprising.
Particularly if you are making your DVD files from an HD original. In that case, not only is Compressor making the appropriate file, it’s also converting your video from HD to SD. One BIG way to increase the speed of the render is to do the conversion first and THEN make your DVD file.
That’s one huge advantage of our AJA Kona boards internal to our Mac Pros. We can convert HD to SD in realtime first, and then render the HD file to BluRay and the SD file to DVD. The DVD files are created in almost realtime that way. Maybe 90 minutes for a one hour movie, usually less.

Walter, I’ve seen you discuss this a few times. I know I can use my LHe to convert HD to SD tape (Digibeta or Beta SP, but how do you convert it to a SD quicktime file that I can bring into a DVD? I’d love to see a tutorial on this.

You simply play the file out through the Kona. Either to another computer or to a tape deck. If you lay it out to tape, you bring the file back in.
If you captured it to another computer, you’re ready to go.

never even thought of that. Great idea. I suppose we could use the Mini as well…..
