I did a video rendering comparison to see the motion using a 960x544@24p RAW video from 600D.
There is no doubt for me anymore. Alien Skin BlowUp3 is the winner. No other can do a upscaling with aliasing free results as it does. also the objects edges does not tremble like in the others. the human face skin texture is good. The small amount of plastic look can be easily solved with a small amount of film grain simulation. It looks like it was shoot with a fullhd camera.
The tips are: enable defringe in ACR to remove color fringing, do the sharpening in ACR (30, 01, 10), do noise reduction in ACR: luma between 30 and 60, chroma 100 (detail zero in both), do the color and luma corrections as you like, render a 960x540 jpg sequence, import all jpg into LightRoom, and apply BlowUp3 using the batch processing (remove all sharpening from it, just enable 200%, or the upscaling amount you need), then render the upscaled jpg sequence into a video file with film grain applied to it.
BlowUp3 render times are faster also: 2,6x faster than PhotoZoom5. PhotoZoom, InstantHD, SizeFixer, PSoft and Retouche do not remove all the aliasing, and the residual aliasing from them is big enough to annoy the eye and small enough to be removed by another filter. For a perfect film look removing all the aliasing is a must and BlowUp3 can do it. Of course in some thin lines and distant trees BlowUp3 also leaves a small amount of aliasing, but I found these situations are impossible to solve. Also BlowUp3 residual aliasing in distant trees and thin lines is always smaller than the other solutions, and the film grain disguises it in a good way, giving an analog chemical film look to the image.
Also remember you can shot 1344x768 @12fps and 1664x944 @8fps in situations where there is not too much motion and convert to 24p with avisynth or twixtor. This just works good for situations with very small motion. 960x544@24p is the way to go for common situations using the tips posted here.
T3i 600D is a low budget "Magic Cinema Camera" now. The worrkflow is a little hard to do, separate audio recording, sync audio in post, long rendering times for dng conversion and upscaling, and so on... Due to this I still believe in good picture styles for fast and easy work in fullhd with sharpening and grading in post. Good to have all the options.
