Q: How to eliminate juddering in panning shots?
Hi everybody,
here's my problem -
My Sony camcorder records m2ts files in 1080/50i (or 1080/25i as Apple/FCPX calls it). To achieve maximum compatibility to Apple TV 4, I'd like to export my film as m4v in 1080/30p. But when I do, I see some annoying juddering during pan shots that drives me crazy and spoils every viewing experience. Those judders are visible on my iMac (when watching the film with QT or VLC or similar) as well as on my Apple TV via iTunes.
Now here's the thing - if I watch the original m2ts files using VLC, I still see the same juddering. BUT with "deinterlacing" set to on and "deinterlacing mode" set to "bob" (both in VLC), those judders are immediately gone and the panning quality is brilliant!
Now, how do I achieve this quality using FCPX/Compressor 4 on 1080/30p ?
I have already tried many many settings within FCPX and Compressor. Besides, I tried to deinterlace my original m2ts files using Handbrake, but to no avail so far, my panning shots still look jerky and juddery. So either I'm not able to find the proper settings or it's simply not possible with FCPX/Compressor - which I can't believe. VLC can do it while viewing (as described above), so FCPX should be able to achieve this as well while encoding, right?
Can anybody help me or point me in the right direction....?
Thank you all!
Best,

Hey,
thanks every for your hints, but the solution was easier than expected. I found out that the Apple TV can handle 50p video just as easily as 30p video after all. So all I had to do was setting up a FCPX project with 1080/25i (as my original files are in 25i too, as mentioned), copy the clips and transitions from the original timeline of the old 30p project and then send the new project to Compressor. There, I just switched to 50p in video settings - and that was it! Compressor does the rest on its own, it creates progressive frames from the interlaced original frames, thus doubling the frame rate.
The result are silk-smooth panning shots, just as I wanted them to be. And as I said, Apple TV handles these exactly the way that 30p video is handled, even though the "Apple TV" compatibility list entry in Compressor is greyed out when switching from 30p to 50p.
Thanks again every, I hope my experiences can help others too!
Best,
Gero
