Are you trying to use the new warp stabilzer?
I haven’t used it but I think it might be overkill for this shot. Can’t you just do an old fashioned point track to stabilize it? If you track two points you can stabilise the position and rotation and it won’t add any of those artefacts.
From what I’ve seen in the demos the warp stabilser is good when you have a camera moving through a scene. This looks like that camera is just hand-held to the movement you want to stablise is much more of a 2D problem.

Fair enough. You can get close if you repeat the process lots of time with a small blur value.

The PS3 won’t play .mov files. If your QuickTime is encoded in h.264 try just changing the extension from .mov .mp4, I can’t remember if that works. If not you can use QuickTime to export the file as an .mp4 without having to re-encode it.

You can create your own version of this. I know it works in Nuke but don’t have AE to rebuild it in. If you premultiply your image with your matte, then blur it, then unpremulitply it this will take the colours at the edge and spread them out.
If you do a large blur you will lose detail from the edge but it will spread a long way. If you need to keep the detail you can use a smaller blur and repeat the process multiple times.
Once you have spead the edge out you can combine this new edge with the previous RGB and then premultiply the new image, with the spread out edge colour, with the original matte.

If you work entirely on a Mac (and never use the Terminal in OS X) you don’t need to worry about spaces. The operating system deals with it for you.
But if you ever need to use the Terminal to run a command line program you will very quickly learn that spaces are a not a good idea. This is also true with web servers and any other UNIX/LINUX OS.
It is worth getting into the habit of using _ or camel casing (oneLongWordWithCapitalLetters) to replace spaces. If you ever have to share your work with people on other platforms or deal with web servers you will make life easier for everyone and you’ll look a little more professional.

They are the best of the best but they are far from perfect. I used to think that I just wasn’t using them right because I got all of these artefacts, then I got to Framestore’s paint department and found out that we had to clean up loads of the artefacts before the shots could be used. I spent weeks working on a re-time clean up on Clash Of The Titans. We used Twixtor and Kronos and mixed the best bits of each together and then we still had to paint bits by hand.

Have you used these time remapping plug-ins before? They always produce artefacts. How do you know it’s the camera’s fault and not just you expecting too much from the retime?

If have a massive sequence that takes a long time to render I will always render to an image sequence, like tifs, then re-import that into After Effects and quickly render that into a QuickTime or AVI file. That way if something goes wrong halfway through the render you still have the frames that are already complete and you can just restart from where it failed. Also if you get glitches on individual frames you can just re-render them.
Once you have the image sequence then it’s much faster to convert that into what ever format you need, QuickTime, AVI, etc

Rotoscope it, sometimes you spend longer trying to avoid roto then it would actually take to just do it.
