Important point: Currently, it’s not possible to upload your video file to Tilda, but you can use third-party services that provide a direct link to the video file.
Some of the popular cloud services also provide a direct link to a file. For example, to get a direct link to a video file on Dropbox, you need to replace the dropbox.com link with dl.dropboxusercontent.com. You can also upload the file to your hosting services such as Selectel, and others.
