Less is enough.

Choose Which Video Formats LessFlux Should Process

LessFlux allows you to control which video formats are included in the optimization process. This helps you avoid unnecessary processing and ensures only relevant files are optimized.

For most websites, keeping all supported formats enabled is the recommended approach.

Where to find this setting

  • Go to LessFlux settings
  • Open the “Video Options” section
  • Select the formats you want to process

Available video formats

LessFlux supports the most common video formats used on websites:

  • MP4
  • MOV
  • AVI
  • WebM

Each of these formats can be optimized without requiring manual conversion before upload.

How format selection works

The selected formats determine which files LessFlux will process.

  • enabled formats are automatically detected and optimized
  • disabled formats are ignored completely

If a format is not selected, LessFlux will skip those files and mark them as ignored.

For most websites, all formats should remain enabled.

  • ensures all video content is optimized
  • prevents large files from being skipped
  • keeps behavior consistent across your media library

This is especially important if you upload videos from different sources.

When to disable certain formats

You may want to exclude formats in specific situations:

  • you only use one format (for example, MP4 only)
  • you want to avoid processing legacy formats
  • you are troubleshooting optimization issues

Disabling formats should be done carefully, as it can leave large files unoptimized.

Common mistakes

  • disabling formats without checking what files are actually used on the site
  • assuming format selection controls compression level
  • excluding formats and forgetting they exist in the media library

Format selection only controls which files are processed, not how they are optimized.

Best practices

  • keep all formats enabled unless you have a clear reason not to
  • verify which formats your site actually uses before making changes
  • avoid excluding formats during initial setup

Choosing the right formats ensures that LessFlux can optimize your entire video library without leaving gaps.
