BTW, I had a similar problem recently. I did some motion tracking and the result looked perfect in RAM preview. When rendered, it looked like crap because everything was jittering around like crazy (as far as I can tell, everything related to field rendering and so on was set correctly). Because I couldn’t find a proper solution, I just saved the RAM preview and used this as a proxy, which of course worked fine.
I think this problem could have the same reasons… but this time I can’t use that solution, since the whole movie is 3 minutes long and so I can’t make a complete RAM preview :/

Hmm I can’t find that option anywhere. Under “Preferences”, I’ve got “Preview…” and “Video Preview…” but neither of those has settings for field rendering. And I also couldn’t find a settings dialog explicitely called “RAM Preview”…

Okay, that seems to be a cool tool 😉
The problem is, though, that the smoother seems to connect the most extreme points’ keyframes, and so if my jittered motion contains peaks, those will still remain. In my case, the smoother should omit those peaks if he notices that all the surrounding keyframes are different.
The footage has fields, but I don’t think that that’s the reason, because I interpreted it as field footage and on sharper pictures it works perfectly. The problem is just that the footage has been shot by night and is grainy and blurry :/

Well with AE automatically separating fields I indeed meant the interpretation of the footage.
When I interpret footage as interlaced, AE won’t show me the typical lines in fast movements, so I guess it somehow interpolates, and my first thought was that AE shows 50 frames instead of 25, but those 50 with interpolated lines.
Now I saw that it’s still 25 frames, so I don’t know exactly what AE is doing. But when you set the framerate manually to 50, you can scroll through the whole animation and it seems incredibly smooth, so I guess in that case it’s done like I usually thought.
For me, it would be important that my interlaced footage will be still interlaced in the final product and having no information loss (let’s say if I wouldn’t do anything to the footage, just put it into a comp and export it back).
I also saw some tutorials about removing fields (or de-interlacing) manually, but I think that’s only important if you want to mix interlaced and progressive footage or if you want to produce videos for being watched on a computer.

Perfect!
This is exactly what I’ve been looking for. I’ll try it out immediately 😉

Well, for my project I don’t think that I’d have to scale and rotate very much (but who really knows that in advance :), so the main stuff that I’d have to do would be color correction, cutting, blurring, well stuff like that. Of course adding some extra layers for text and doing some masking stuff, but the footage itself is shot in a way it should also look in the final product (regarding size, zoom, and so on).
I think I’ll have to experiment a bit…

Thanks for your answer!
For 1), well the way that I understood is that although I’ve got interlaced 25 fps material, AE does me the favor to display it as 50 fps by doubling the lines (or interpolating) so that I can edit the video in a better manner than if it would show me the real 25 interlaced frames. But the video itself IS still interlaced, of course, and when I render my final video, those “doubled lines”, and all the effects that I made onto those single frames, will be put back together into 25 fps interlaced.
So that way, there should be no information loss to my original material and my final 50 half-frames should still be like before (if I didn’t use effects of course 😉
I hope that’s correct, because I produced some material with a PAL camera and I’d like to have the same interlaced quality when I watch the final thing on a TV screen.
So, again in a nutshell, video resolution and fields etc remain untouched, but for my convenience, AE displays me 50 full frames with doubled lines or interpolation, so that I can better deal with effects and so on.
I hope now it was a bit clearer 🙂
