Guides: find and fix stutter in your export

Duplicate frames almost always come from the same places: frame rate conversions, speed changes, transitions or footage with a variable frame rate. Each guide shows how to recognise the cause and how to fix it in Premiere Pro and After Effects.

• Video stutters after export – find and fix duplicate frames

  Smooth in the timeline, a hitch in the export: how to recognise duplicate frames, what causes them and how to find them in your project.

• How to detect duplicate frames in a video – options compared

  Video QC before delivery: by hand, with FFmpeg (freezedetect, mpdecimate) or with a QC tool – what each option finds.

• 23.976 fps in a 25 fps sequence stutters – cause and fix

  About one stutter per second: why 23.976 or 24 fps footage catches in 25 fps and how to fix it with Interpret Footage or Optical Flow.

• Slowed-down clip stutters – speed below 100 % in Premiere Pro

  A clip at 91 or 95 % speed catches every few frames. How to find the speed change and make the slow motion smooth.

• 25p in 50p: every frame doubled – error or delivery format?

  Every frame appears twice: when that is fine with 25p in 50p and how to get real 50 frames or a 25p export.

• Stutter at a cut or transition – repeated frames at the start or end of a clip

  A frame is duplicated right at the cut or in the transition: when the footage runs out – and how to fix it.

• Phone and screen recordings stutter in the edit – variable frame rate

  Phone and screen recordings with a variable frame rate: where the irregular hitches come from and how to convert before editing.
