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 — no waiting.
You can also toggle low-res mode from the Setup panel on the left-hand toolbar — look for the Edit faster option.

​
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.

​
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, please contact support so we can investigate.
