Upload a video ​

Upload a recording to a project so you can annotate it. Large files are sent in parts, so a short network drop does not stop them.

The Upload Video window, with the area where you drop a video file and the Spoken language menu under it.

Before you start ​

Your file must be MP4, MOV or WebM. The largest file is 2 GB. A file over 64 MB is sent in parts of 16 MB. A file between 500 MB and 800 MB is made smaller in your browser first. A file over 800 MB skips that step and uploads as it is.

Steps ​

  1. Open your project. Its video list opens.
  2. Click Add Video. The upload window opens.
  3. Select a language under Spoken language. This step is optional.
  4. Drop your file on the dashed box. You can click the box to browse instead.
  5. Wait for the bar to reach 100%. The video opens in the annotator. For a file over 64 MB, the line under the bar also counts the parts, for example "part 3 of 110".

Keep the tab open the whole time. Keep the computer awake too. If the network drops for a moment, GRAPE MARS sends that part again by itself. A page reload ends the upload, and it does not resume.

You can start from the Projects page instead. Click the arrow beside New Project, then Upload a Video. That window asks for a project name first. It then makes the project and uploads in one step. The button reads Create Project & Upload.

Check it worked ​

The video plays in the annotator. Go back to the project. The list shows a row with your file name and its length.
