Filmora Video Lagging After Export

Workaround available Windows, Mac Updated October 21, 2026

Quick answer

Choppy exported video usually comes from a frame rate that doesn't match the source, wrong output settings or corrupted clips. Match the project frame rate to your footage, use a built-in export preset, and update Filmora and your GPU driver.

Most likely fix: Match the frame rate.

Symptoms

The exported file stutters, skips frames or looks jerky even though the timeline looked fine.

Why it happens

  • Export frame rate different from the source footage
  • Incorrect custom output settings
  • Outdated GPU driver or Filmora build
  • Corrupted source clips

How to fix it

Try these in order — the most common fix is first.

  1. 1. Match the frame rate

    1. Check your source clips' frame rate
    2. Set the project and export frame rate to the same value

  2. 2. Use a built-in preset

    1. In the Export window choose a YouTube, Vimeo or device preset instead of custom settings
    2. Export again

  3. 3. Update Filmora and the graphics driver

    1. Help > Check for Update
    2. Install the latest GPU driver from your GPU or laptop maker

  4. 4. Enable GPU acceleration for rendering

    1. File > Preferences > Performance
    2. Enable both hardware acceleration options and Apply

  5. 5. Replace damaged clips

    1. Play each source clip outside Filmora
    2. Re-encode or replace clips that stutter there too
