Hey Tolero,
You are welcome. Yes, there are a lot of small adjustments that can be made with your geometry and shadowing technique to improve the movie capture quality. Usually when we are flying around in the viewport creating content and designing our levels/scenes, the smaller details like the sharp edges and overlapping areas can sometimes get overlooked. These are more noticeable when creating a rendered video through a camera that is slowly flying around your scene focusing on individual sections of your environment.
Quick question, have you used the AVI movie option and rendered to 30 frames per second? I have found that upon initial capture of a movie, it will appear washed out, but if you go to the directory where the movie is saved in your project folder and play the movie, it will look as intended. By ‘render individual frames’ I just meant taking the individual frame images that are created when using the sequence and compiling them with an external movie editor.
The points you bring up are valid and your workarounds sound like they will do a good job on cleaning up the overall smoothness and quality when rendering your video. Let me know if you are able to get your movie to the desired quality, or if you have any other questions or concerns.
Cheers,
