It took a lot of messing around but finally I found a setting where the slowed footage works at about 1 third speed. I was up very late playing around with the slowed version tying it with and without dissolves. In the end I had some footage I really liked it seemed to have greater impact that just the standard speed a final version at last.
But not quite morning came, the morning of the critique and I had to copy of the renders to take in to , I thought I would take a slow and a full speed one to show, but when viewed the slow motion version it didn’t seem to have the impact, the full sped one felt much stronger in comparison. Maybe its just my paranoia, I’ld wait and see how it went down.
