REAL DETAILED INFO for anyone up to the CHALLENGE OF SAVING THE DAY!~ (in regards to compatible/appropriate sequence settings)
My video is totally distorted and I don’t know what to do. A production house used Blackmagic to import the beta footage onto our harddrives. I downloaded blackmagic onto my computer. Within Final Cut 5, I cannot solve the distortion issue- hense I cannot export an appropriate video- so believe that somewhere in the mess of my settings in FCP- something terrible is being overlooked.
I have a sequence set at:
Frame size 720 x 486
Aspect Ratio: CCIR NTSC (40:27)… (The only other CCIR options to choose from are CCIR 601 NTSC Sq. (4:3), or PAL…)
Pixel Aspect Ratio: NTSC – CCIR 601/ DV (40:27)
Field Dominance: Lower (Even)
29.97
QUickTime Video Compressor: Blackmagic – Quality set for high
Video Processing Motion Filtering quality: BestI have a clip with item properties set at:
Frame size 720 x 486
Pixel Aspect Ratio: NTSC – CCIR 601
Field Dominance: Lower (Even)
Video Rate: 29.97 fps
Compressor: Uncompressed 8-bit 4:2:2
Data Rate: 20.3 MB/secI tried the sequence setting compressor as uncompressed 8-bit 4:2:2 before as well and was getting the same distortion issue.
When I export a quicktime movie i choose format- qtmovie with compression at blackmagic 8 bit.
when i use compressor and convert it to an mpeg4 the footage has issues.What should I set my sequence setting to, and how should i export so that i may finally get this footage to DVD. PLEASE PLEASE HELP.
Much appreciated. -

The image has an interlacing problem- and not just because i am watching it on the computer monitor- because i have printed to dvd and the interlacing issue is still very much apparent when i watch it on a NTSC monitor. The image looks great (color,detail), except for when there is movement, and the movement is staggard/blurred/choppy… whatever- all of the above! I really am not sure how to solve this problem, but yes i am worried that when i export the file- it will not export properly. (The compressor will also not allow me to change the geometry setting to a “720×480 mpeg2 file” as you had said, and is locked in as 720X480 (and i am not sure how to go about changing that).

yes absolutely- and it doesn’t work on the home TV. I’m really confused. Ummmmmm…. I’m picking my brain for answers.

We had problems in the past exactly like the ones you describe. Does it look like the fields are reversed? – Does the image tear horizontally in clips displaying high motion?
If so… Instead of exporting with quicktime conversion directly out of FCP… just add one more step…
Export a refrence movie out of FCP with “Current Settings”. Quit FCP drag regrence movie to compressor and encode to Mpeg2. Using this method, compressor seems to get the field order correct. It seems to be an issue of uncompressed 8-bit footage being 720×486 and DVD’s being 720×480.
I bet this works.
Do I win the prize for solving the puzzle?

PLEASE DONT LEAVE ME Adam Duplay!!! I’M GONNA TRY TO DO WHAT YOU JUST DESCRIBED… Q-though–HOW DO YOU EXPORT A “REFERENCE MOVIE”? Do you mean that I should just simply export a “quicktime movie” as is?? I’ll try- but please dont sign off!!! I NEED YOU! Thanks man, -Jaclyn.

This is problem we have with 720×486 movies: iDVD fouls up the field order. I had to even go another step in Compressor and force it’s mpeg-2 settings to “Lower” fields and not “Automatic.”
You don’t necessarily have to export a QT, you COULD “export using compressor….”

[jaclynvt] “HOW DO YOU EXPORT A “REFERENCE MOVIE”?”
Export -> Quicktime movie and make sure recompress all frames and Make movie self contained are UNCHECKED.

naw, iDVD 3 was totally fine with 720×486. 4 had problems on “best” encoding. 5 just doesn’t work.

You have to let us know if it works.

just a little one.Surely if you are doing work at 8bit, your field dominance needs to be set to Upper, not lower. In the sequence settings and everywhere else. I have seen this jagged movement with moving pictures before. Then when exporting to Mpreg or perhaps a DV movie for a DVD, change your sequence settings to DV, and field dominance to lower. This is how it works with PAL over here in the UK.
Certainly the jagged images sound just like a field problem.
Let us know, best wishes

Problem seems solved: I download the Blackmagic Installer and installed it completely. The codec and setups finallly worked (previously only the codec was loaded). I used the Blackmagic Sequence Preset. I saved the sequence as an uncompressed 8 bit QT. Then just dropped the QT into DVD Studio Pro and let it figure out how to compress the file. The DVD looks good.
Thanks for all your help
