Currently, it is not possible to upload a video to Trayn, but we support a variety of different video platforms without any changes.
We suggest you link "unlisted" YouTube videos. They are very fast (crazy servers) and can be opened on any device, and as with DropBox only someone with the link can open the video.
Self-hosted videos
If you self-host your videos, you can add the direct URL to your video file
Supported video platforms
You can also provide the link to the YouTube or Vimeo video and we will show the video in an appropriate player.
We also offer a Dropbox integration.
Unsupported video platforms
WeTransfer
We have already received several requests to support WeTransfer as an integration with Trayn. There are, however, a few problems why we cannot do this. Only, if you have a WeTransfer pro account, files are stored permanently on WeTransfer. Additionally, WeTransfer does not offer a programming integration we can use in Trayn to show a nice preview image as we do with DropBox.
