1:1 SD Avid Nitris, Up-rez (Please Help!)
I am working on an Avid Symphony Nitris v 1.0. The system does not have a Mojo. I began my project on an Avid XPress Pro, and now I am trying to finish.
I am trying to up rez to 1:1 SD media, which resides on my external hard drive as uncompressed QT files. I batch import, and the media shows up and says 1:1 in the bin. However, it is definitely not showing 1:1 media.
I can even play my uncompressed QT original media next to it and see the difference. If I had to guess, it looks like the media is capping out at a DV50 compression, but there is no way to be sure since it says “1:1” under Video in the bin.
Please help. I need to finish at 1:1, and my time is limited! Thanks in advance.

where did the quicktimes come from?
Sounds like they are comressed and just imported at 1:1.

They came from the telecine lab. The lab did a telecine and transferred to digi-Beta tapes. Then they used some software to transfer them uncompressed.
The files, when I just play them in Quicktime, look just like the tapes. They look great. When I import them, supposedly “1:1”, they look horrible.
I can even open a QT window right next to the composer window and compare the quality, so the problem is not in the original files.
Any ideas?

If it helps, the codec on the original QT is YUV422.

If you’re comparing your quicktime player to your composer monitor you’re going to see a quality difference. Unless the Nitris is different the Media Composer, it only shows 1 field.
Have you viewed these on a client monitor? It’s the only way to really judge the quality of your file. Or you can try importing the quicktime, export a quicktime reference, and open that in your Quicktime. Do you see a quality difference there compared to the original file? It should look the same as your original quicktime, and at least that way you’re comparing the quality in the same program.

I imported and then exported a “same as source” QT and then another Custom Options QT with Compression as “None” and “Millions of colors” (which is the original file). The exports are worse than the original when played in QT.
This leads me to believe there is some problem with the import.

but agin, are you looking at playback on an ntsc monitor?
Also, if they lay off to digibeta, you won’t have uncompresse files as Dbeta compresses at 2:1.
