I have a brand new Macbook Pro 15″ i9 Model with fully updated Premiere and Mac OS and mine does exactly the same thing. I haven’t used interpret footage that much recently so I dunno if this is a problem with the most recent update, but given Premiere’s track record, i doubt they know or care.
Scrubbing through interpreted footage coming from 60p and 120p both skips and glitches to the point where you might as well not even try, it’s impossible to find anything.
Does anyone have any workarounds for this?
