This is largely defunct now as framepack does a much better job and Anything Everywhere nodes are currently non-functional. Trimmed version here.

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.

(The low ql version may look VERY different from what you end up with, also this can cause OOMs on a 12Gb card with what seem to be sensible settings)

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.

Cheers to tedbiv for assisting, testing and Lebofly for suggesting the fix to combine the vids into one file.
