Interlacing probs when rotated 90 degrees

I have some video that was shot on a Sony HC3 rotated 90 degrees. It was in a discotek and when I rotate it back it has terrible interlacing problems. Is there anything I can do, or am I up a creek w/o the proverbial paddle?

1. Try reversing field order in that one clip.

or

2. Try supersample = 2 (it's an envelope on the Video Bus -- you have to enable the video bus view and then you add the supersample envelope). This isn't really what the supersample is intended for, but I have found that it fixes other field reversal and interlacing problems. Try it on 5 seconds of the video and see what happens.

IMO,id be juicing my project file as progressive scan

deinterlace the bugger and u wont have an issue

I do alot of sideways shots for corporate clients who like to run Plasma panels side by side vertically, neverhad an issue when converting to progressive, or even shooting progressive

John,
Thanks for the supersampling tip. I had tried forcing supersample in the properties along with changing project and clip properties to all the progressive/interlaced possibilities and nothing fixed it.

The video bus supersample at 2 fixed it, but as you probably know, it doesn't make it perfect. There are lots of flashes of light that make blending frames get a funky result, but it is better than what I had.

Thanks!

Take a look at the project properties. Do you have any deinterlace method selected? If it's "none" change it to "blend" or "interpolate".

Marco,
Thanks for the idea, but changing those options didn't do anything for it.

well thats bizarre.. by converitng it to progressive, interlacing artefacts shoud be non existant.
