Interlace artifacts?
We are a newly formed production company near Hartford and have been trying to solve an export/delivery problem with short-form projects. I will try to be concise in my description of the situation, and greatly appreciate any assistance that is provided!
System:
Dual core 2.66Ghz, 8GB ram, ATI Radeon 1900 graphics, 23″ cinema display, 1TB internal storage, FCS6 newest upgrade version.Project:
:30 TV commercial with a combo of HDV 1080i 60 16×9 footage from a Canon XHA1 and stock photography footage. Fonts generated in Livetype and or Motion. Sequence is Pro-Res 422. Exporting with Compressor, burning to DVD with DVD Studio Pro.Problems:
Once project is complete in FCP with no artifacts, we burn it to DVD with VBR of 5-6Mbps, 2 pass. We have tried numerous variations and inevitably have a very poor quality DVD when viewed on numerous consumer DVD players and TVs. There are motion artifacts/tearing on any fast moving video or fonts, and font edges are not sharp, but stair-stepped. We have tried de-interlacing both in the FCP timeline and with Compressor. We have tried exporting at the highest possible settings (Pro-Res HQ, 10 bit uncompressed, etc.) with little success.This shouldn’t be this hard! We are very frustrated and have enough television experience that we should know what looks good as a final product. We are hoping that there is something simple we are overlooking that would be a simple fix, or the possiblity that our system is possessed.
Thanks for any input!!!

HD footage will be upper field first. SD footage will be lower field first.
Are you correcting the field order for the HD put into an SD timeline or are you editing completely in an HD timeline?

Hi Walter,
Good question, and I will confirm this evening. What I can tell you is that the sequence setting is the new Apple Pro-Res 422 codec, and and the option “conform media to sequence settings” (or something like that) was checked. It is my understanding that the Pro-Res allows multiple formats to co-exist in the same timeline witouth user intervention/conversion…but I could be wrong.
I appreciate your assistance and will update the board with the sequence settings later tonight.

This is a bug that seems to have started with the Quicktime 7.2 update. Please use Apple’s feedback forum to let them know.

Under the sequence settings General tab it goes like this
Frame Size: 720X540 CCIR 601 NTSC 4X3
Pixel Aspect Ratio: NTSC-CCIR 601/DV 4X3
Field Dominance:: Lower
Editing Timebase: 29.97 FPS
QuickTime Video Settings
Compressor: Apple Pro RES 422 HQ
Quality: 100%
Audio Rate 48K
Depth: 16 Bit
Config: Channel Grouped.I posted this problem on the Apple FCP forum…is there a specific “Feedback Forum” that is directed to Apple, versus users? In regards to the QT 7.2 bugs…should we uninstall QT and try installing a previous version?
Best…Alex

“Google “Final Cut” and “Feedback”.
Downgrading QT might be a good idea. I’m going to as soon as I get a chance.
I have an Intel Mac Pro. One of my co-workers, who’s using a PPC G5, has QT 7.2 and doesn’t seem to have this problem. I haven’t tested it on his machine myself, but he’s outputting web clips of film-based 29.97 footage using Compressor’s deinterlacer (he uses blur deinterlacing) and they look fine. I’m unable to do that on my machine. It’s combining the wrong fields no matter what options I choose.

Thank you for the google terms! They worked and brought me to the feedback age, where I left the bug report. Very interesting on the difference you mention between your 2 test machines…I will go to Quicktime and attempt the downgrade…after a cursery look on the QT page I didn’t see the option to download a “downgrade” to a previous version, any ideas? I am somewhat hoping that there’s an issue with the Intel Pro system and QT, and maybe a simple fix is near! I am considering the $799 Applecare Pro-Video support package…do you think this is a worthwhile investment?
Thanks for taking the time to respond, it is really appreciated…Alex

I don’t know the steps to downgrading. But I know they can be found somewhere here on the Cow.
I’ve never bought the Applecare Pro package. It may be worth for you. If you get an AJA product, their free tech support is fantastic.

Alex,
Can you please post a clip that shows the tearing? Have you come to any conclusions regarding the problem?Thanks,
David

Hi David,
Well, it was a long, painful process, but the short of it follows…
There was too much transcoding going on, and at the wrong places. I will dig up the exact routine later tonight and post it, but one of the main tricks was exporting the HDV timeline before fonts were added as a QT movie with a DV50 codec, then creating a new timeline with this setting and adding fonts. Like I said, I will post a more complete description once I confirm with my edit partner.
In order to get this solution, we purchased the $799 Applecare Pro Video support package, and spent a while on the phone with someone from Apple in CA to work through the details. We have this service for a year and hopefully will find more use for it!
Thanks for taking the time to read and inquire…have you had similar issues in your travels?
Best,
Alex
