how can I prevent that a 640x360 (360p) screen recording video (mpeg4) becomes blurred in a 720p (1280x720) project that is rendered to 640x360? - I need 720p videos (no screen recordings) in the timeline for some effects (crop, zoom, ..).

So I have pixelated faces out of a project, at points frame by frame adjustment was neccesary as obviously the motion tracking is not perfect.
Everything looks tidy in the project monitor but not in the rendered videos where the square moves differently and occasionaly doesn't cover things.
More strangely the pixels do different things depending on the render format, h.264 has slighlty different result than HDV and 2 passing gives diferent result again.
I've tried to make a chroma key using a green screen and a photocamera (I don't have a video camera, this is the possible first problem).
The screen is uniform ad flash green, the light was quite good but, the final results is full of, I don't know how to decribe, but seems as video glitch.
Every border are really not sharp. I've tried a lot of setting with variance and I've also combined more than one chroma key.
Some of you have ever used kdenlive with chroma key?
Have you achieved good results?
