DVCPROHD to SD – Interlace and Banding
I have searched the COW for days regarding this issue and haven’t come up with a complete answer.
I am mastering a series of commercials shot on a Panasonic DVCPROHD camera at 720p 59.94. The final output has been on a SD Beta Tape.
I am editing all these spots in a 720p HD 59.94 timeline and use an AJA Kona LHe card for letterbox output to my beta deck with great looking results. However, every fine line in the footage produces horrible looking banding and buzzing when the camera pans or tilts. I have tried all the tricks – flicker filter, adding a second layer with overlay and adding guassian blur… you name it.
I am convinced that the solution is in the settings. Maybe field order? Maybe going from progressive to interlaced yields crappy results all the time. I don’t understand how all of these TV shows and spots shot on HD and mastered to SD look OK.
What has everyone here at the COW been doing in this situation?

I have a similar workflow, but going from DVCProHD 1080p30 to SD. And yes, going from progressive HD to interlace SD does yield crappy results (partly due to FCP “bug” as discussed on several other threads here). The best way that I’ve found to do it is to go in 2 steps. First nest the HD footage in a progressive SD timeline. Then output to tape using the AJA to do the conversion for you. Other possibility is to convert from progressive HD to interlace SD using Compressor.

So really, the results aren’t that great.
How have you setup the down convert?

I have the AJA converting to 525i 29.97 to letterbox. By great looking I meant the down convert was clean (besides the interlacing issue)

Any more ideas?

Sorry blue, but I don’t see what you are seeing. Any chance you can post a few seconds of the problem area so I can take a look?

Can someone please instruct me on how to upload spots?
