## Upload progress on the canvas

A video, image, or PDF appears on the canvas as soon as you add it, before the upload finishes. The progress shows on the item itself.

### What you see when you upload

- **Videos**: the first frame of your video appears right away. A ring with the label **Loading 42%** sits on top of it while it uploads.
- **Images**: your image appears right away. If the upload is still running after about 5 seconds, the progress ring and percentage appear on top.
- **PDFs**: a page placeholder with the progress ring stays until the document is ready.

When the ring has no percentage it spins, which means Pactto is still processing the file. Very small items hide the label.

### What everyone else sees

Other people in the room see the item appear in the same place, with a spinning **Loading** indicator until the upload finishes. Then the file loads for them on its own.

### Cancel an upload

1. Hover over (or tab to) the progress ring on the item.
2. The icon turns into an X and the label changes to **Cancel**.
3. Click it. The upload stops, the item is removed, and you see "Upload of (file name) cancelled."

Only the person uploading can cancel.

### Imports from Google Drive and Frame.io

The dialog's button shows the progress ("Importing 2 of 5..."). If you close the dialog, the import continues and the progress moves to a message at the bottom of the screen.

## Good to know

- Keep the room open until your uploads finish. If you close the tab or leave the room, the upload stops and the item shows "Upload didn't finish". See [Fix an upload that failed or a file that will not load](https://www.pactto.com/help/fix-failed-uploads.md).
- If an upload fails, the item is removed and you see "Upload of (file name) failed. Please try again."
