Large Videos and Preview Quality
Section titled “Large Videos and Preview Quality”When iCloud Sync is enabled for the board, ArtDeck chooses the video sync tier from the local video file size. Videos up to 100 MB upload the full original. Larger videos sync a smaller HEVC preview first, up to 720p, so the clip can appear and play on your other devices without uploading the original right away.
The device that imported the video keeps the original file. Other devices receive the preview until you or the source device chooses to upload the original.

| Status | What it means |
|---|---|
| Preparing preview for iCloud | The source device is making the smaller synced preview. |
| Preview will continue when ArtDeck is open | Preview creation paused while ArtDeck was not active. Open ArtDeck on the source device to continue. |
| Full video on this device · Preview synced to iCloud | The source device has the original, and other devices can receive the preview. |
| Preview quality · Full video available from source | This device has the proxy and can request the original. |
| Full quality arrives when the source device is online | The original has been requested; keep the source device online so it can upload. |
| Full quality upload paused — will retry when connected | Upload will continue when the source device can use iCloud Sync again. |
Use the quality controls that match the device you are on:
- Source device: Choose Upload Original in the video controls or status card. On Mac, you can also choose
Video > Upload Original Video. - Receiving device: Choose Get Original in the video controls or status card. On Mac, you can also choose
Video > Request Original Video. - After requesting: The receiving device shows Original requested until the source device uploads the full file and iCloud Sync delivers it.
If the upload or request control is not available, the video is already full quality on this device, the selected video is not in a proxy state, or the source file is not available on this device.

For more details, see iCloud Sync.
