And this is what I was wanting to post...
That's from my render or SR-v10, and there are many other examples of chroma-bleeding. Did you correct this in later versions of the script DrDre?
On the topic of telerecordings (/kinescope), I've never heard the term "low definition" applied to 405 and 625 line television. Especially not 625-line. I'm pretty sure you just call 405-line standard definition. Telerecordings reduced the 50i source to 25p by throwing away every other field, and recording it onto film. As the source however was videotape, it never existed in a higher resolution than what's available on the telerecording - it simply had the other fields as well - and you can't recover missing field information from existing fields.
I don't think you can get much out of such a source - the 16mm film doesn't reproduce the exact line-pattern of the source for a start, so you're working at a disadvantage in that you have a source that higher resolution than the material it contains, whereas SR is designed to work with a source that's lower resolution than the original material. Hope that makes sense.
