I'm trying to get slow motion wiht twixtor in Premiere Pro.
When I do that with any other filter on my footage, it seems to be all right. But if I apply "shadow/highlight" Premiere effect after twixtor(and in my particular case I need to do that), appears like a persistent and undesirable flikering every fixed frames. Seems like "Shadow/Highlight" changes one frame every number of fixed frames.
Furthermore, If I apply twixtor after "shadow/highlight" (and not before), then "shadow/highlight" does not work, and that happens with other Premiere effects. It seems like twixtor does not let any other filter to work with it.
You cannot apply an effect before Twixtor in Premiere unless it's within a nested sequence, however you should be able to apply one after unless like Twixtor it's accesses multiple frames per frame.
To apply an effect before Twixtor:
create a nested sequence, drop your footage in it, drop your effect there and then in the main sequence, set the color source to that nested sequence (eg video track 2 or whatever it is)
Are you using PPRO 1.5 or 2? As well does your material have fields?
If it's the same Shadow/Highlight as AE (just got new PPRO 2 this week and have not installed yet), then it has a temporal smoothing option (thus accesses multiple frames somehow), therefore would probably require an additional level of nesting to work in Premiere correctly.
