Low-res mode makes the editor feel faster by using lower-resolution copies of your video while you edit. Your original high-res files are untouched. Tella only uses the low-res copies inside the editor. When you share or export, your viewers always see the full-quality video.
Low-res mode is on by default for new videos. You don’t need to do anything to turn it on, just open your video in the editor and Tella takes care of the rest.

​
Why it’s on by default

Low-res mode helps the editor stay responsive, especially with:
  • Long videos
  • Videos with many clips
  • Large screen recordings (4K or 5K)
  • Older or lower-powered computers
Because the low-res files are only used while editing, there’s no downside to leaving it on.

​
Turning low-res mode off

If you want to see the full-resolution files while editing, you can switch low-res mode off:
  1. Open your video in the editor.
  2. In the top toolbar, click the Low-res button (the flame icon) to toggle it off.
Click it again to turn it back on. Once the low-res files have been generated, you can toggle between modes instantly, with no waiting.

​
Generating low-res files

The first time you open a video, Tella generates the low-res files in the background. For longer videos this can take a few minutes. You can keep recording or editing other videos while it runs. While low-res files generate, Tella plays your original media in the editor. If you add a new clip or video B-roll while low-res mode is on, playback switches to the low-res copy automatically when it’s ready, so you can keep editing without reloading the editor. If a low-res file can’t be generated, Tella stops retrying and keeps using the original when possible instead of leaving generation stuck.

​
What your viewers see

Low-res mode only affects what you see in the editor. When you share or export your video, Tella always uses the original high-res files. ✨

​
Troubleshooting

Low-res mode needs your uploads and conversions to finish first. Wait for them to complete, then try again.
Generating low-res files can take a few minutes for longer videos. You don’t need to wait on this screen. Record or edit other videos while it runs in the background.
If low-res generation fails, Tella uses the original media when available. Please contact support so we can investigate the error.
