aliasing or jitter onFS7 video
We just shot a new commercial, using the Sony FS7, shot in UHD, 29.97. We used Sony’s Catalyst Browse to convert to ProRes 1920×1080, 29.97, as the local station isn’t doing any 4K for awhile.
The footage looks fabulous, but on a Prorez timeline, I’m seeing a little bit of jitter or maybe aliasing, when the camera is panning. I tried using an uncompressed 10bit timeline, and the same thing occurs. When I opened another project, using a Panasonic P2 camera at 720p 60, there was not jitter at all. Even another 4k project doesn’t have that jitter. Any thoughts on why that’s happening and how to fix? I am using FCP 7, and have not seen this jitter on other projects.

The FS7 is well-known for its “rolling shutter artifacts,” which you are now experiencing. Google FS7 rolling shutter and you’ll find a boatload of info on the topic. As I recall, there are some filters available from various companies designed to help mitigate some of the artifacts.

Found the boatload, and now know what I’m dealing with. However, I didn’t see anything that solved the problem. I have some solutions for future use, but a google search turned of nothing by way of any filters or techniques to compensate. I may have to reshoot this commercial if it looks too evident on air. Anyone know of anything I can do in post to reduce?

“Anyone know of anything I can do in post to reduce?”
not in FCP.
id look into other solution like after effects.
maybe motion?
actually i wouldn’t be too surprised if FCPX has a solutionnick
