Local videos are read directly. Cloud videos prefer segmented playback without the 100 MiB whole-file limit. Playback depends on browser codec support and available playback resources.

You can also choose cloud files: sign in, unlock your space and select a file to decrypt locally. Cloud videos stream in segments without loading the entire file into memory.

GET STARTED

How to use Video player

  1. Choose or drop a local video, or sign in and unlock your space to select a cloud video.
  2. Press play. Use the player controls to adjust volume and seek.
  3. Switch to full screen for a larger view. Close the preview to choose another video.

Previewing does not modify your files. Choose local files again after closing the page.

Frequently asked questions

Why is there only audio, or no playback?

A container format is different from its codecs. Browsers do not support every MOV or MP4 codec. Try H.264/AAC in MP4 or VP8/VP9 in WebM.

Are videos uploaded to a server?

No. The player reads the video from your device. No upload or sign-in is needed.

Can I play cloud videos larger than 100 MiB?

Yes. Prepared cloud videos download and decrypt in segments as needed. If playback resources are not ready, check Transfers. Small videos without segments can still use whole-file preview.
