Optimize Videos with LessFlux

Videos are one of the heaviest elements you can add to a website. Even a single unoptimized video can significantly slow down page load times and increase bandwidth usage.

LessFlux helps reduce that impact by optimizing videos externally, similar to how it handles images.

What video optimization does

When enabled, LessFlux processes video files to reduce their size while maintaining acceptable visual quality.

• reduces file size
• improves loading speed
• lowers bandwidth usage
• makes video-heavy pages more responsive

This is especially useful for landing pages, product pages, and media-rich websites.

How LessFlux processes videos

Video optimization follows the same external workflow used for images:

1. You upload a video to WordPress
2. LessFlux detects the file
3. The video is sent to the LessFlux processing system
4. Compression is applied based on your selected preset
5. The optimized version is returned

All processing happens outside your server, so your hosting performance is not affected.

Supported video formats

LessFlux supports common web video formats:

• MP4
• MOV
• AVI
• WebM

These formats can be optimized without requiring manual conversion before upload.

Video presets

LessFlux uses presets to control how aggressively videos are compressed.

• Lower presets prioritize quality with smaller size reduction
• Higher presets reduce file size more aggressively
• The Medium preset is recommended for most websites

Choosing the right preset depends on how important visual quality is compared to performance.

Original vs optimized videos

You can choose how LessFlux handles original video files:

• Duplicate original video and keep both versions
• Replace original video with the optimized version

Keeping the original is safer, especially during initial setup. Replacing originals reduces storage usage but removes the backup.

When video optimization runs

Video optimization can be triggered automatically:

• on upload, if enabled in settings
• manually through bulk processing

Like image optimization, video processing runs in the background and may take longer depending on file size.

What to expect during processing

Video optimization is more resource-intensive than image optimization, so processing times are longer.

• larger files take more time to process
• results are not instant
• you do not need to keep the browser open

This is normal behavior and not a sign of a problem.

Common issues

If video optimization is not working as expected, check the following:

• video processing is enabled in settings
• the format is supported
• the file is not too small to require optimization
• your quota has not been exceeded

Logs usually provide clear information if a video could not be processed.

Best practices

• use the Medium preset for most use cases
• optimize videos before embedding them on key pages
• avoid uploading unnecessarily large video files
• keep originals until you are confident in results

Video optimization can significantly improve performance, but it should be used with intention. Focus on reducing file size where it has the most impact.
