Create a chain of videos using the last frame of the preceding vid as the first of the next. This can be scaled up to make even longer videos albeit at a reduced coherence.

v1.31: Rearranged and tweaked. Trimmed the overambitious 3rd section as it's results were usually iffy at best, added optional upscalers for each section.

Remember to set all switches to the same number as the Process Picker. Errors like so:

'Node <number> says it needs input value1, but there is no input to that node at all'

Are down to those switches being on mismatched numbers.

This is still a work in progress. Cheers to tedbiv for assisting, testing and Lebofly for suggesting the fix to combine the vids into one file.
