Screen recording looks pixelated and glitchy when sped up

[Jess Summers]

Hi there,

I'm importing a screen recording of some design work - usually around 4 hours and using Speed/Duration to speed it up to about 25 mins. I've tried using optical flow, frame sampling etc but it all looks bad.

Any thoughts or suggestions?

Many thanks in advance

If the footage is variable framerate convert to constant framerate with Handbrake or Shutter Encoder before bringing into Premiere.

thank you I'll give that a shot.
