Change Playback Quality

You can adjust the playback quality of the Preview window for a smoother editing experience. For example, you can improve the performance of your preview by playing your video at a lower resolution than you want for your finished project or by creating proxy media files to edit with.

Note:
Proxy files are more manageable versions of your clips that are easier to edit because they are smaller in terms of data (i.e. they are at a lower resolution). You can edit with a proxy file in Filmora, then export with your full-sized original clip.
  • If Filmora detects lags, it will prompt a message to ask you to lower playback quality.

  • Reducing your playback quality can eliminate lags and save you time. Click the playback quality control menu, and then choose from these options:

  • Full: preview your video without changing the original resolution
  • 1/2: preview your video at 1/2 the original resolution
  • 1/4: preview your video at 1/4 the original resolution
  • 1/8: preview your video at 1/8 the original resolution
  • 1/16: preview your video at 1/16 the original resolution
Note:
The reduced playback resolution only applies to the video preview and will not affect the export settings.
