So I got myself a Cannon PowerShot SD980 that takes 720P HD video at 30fps. I use Adobe Premiere CS4 to edit and render my videos. I already successfully created several videos that consist of just still images just fine. I rendered them at 1080P 60fps VBR @ max, 2-pass. Worked fine.
Now I created a video that consists of parts that are at high speed (200%) like to speed up areas like mini time lapses. The finished product however seems to be kind of choppy and slow and definitely not as smooth as the originals.
I've tried everything from changing the sequence setting from everything from 720P 29.97/30 fps VBR default and 1-pass to 1080P 29.97/60fps 2-pass. I get the same problems.
I've also tried changing the exporting media settings all over the place. Including matching the sequence settings to the export settings, making them both match the original videos properties. So that EVERYTHING was set to 720x1280 30fps, still no success!?
