Read guideFrequently asked questions
Can AI recover details that are missing from the source?
No. AI processing estimates or synthesizes visual information; it cannot recover the exact scene detail that the camera did not record. Keep the original and review the output for artifacts.
How should I choose settings?
Start with a modest setting and test a short, representative section. Compare the result at its intended playback size before processing more footage.
Does a higher setting always look better?
No. Stronger processing can increase output size or smoothness, but may also make artifacts more visible. Choose the least aggressive setting that meets your goal.
