If your face swap video looks blurry, choppy, low quality, or does not preserve identity well, the source media is usually the biggest factor.
Face Swap Video works best when the source face is clear, front-facing, and visible throughout the clip.
Best practices before you render
For the best result:
use a clear source face image
use a well-lit video
keep the face large enough in frame
avoid extreme head turns
avoid motion blur
avoid heavy shadows, hair obstruction, or sunglasses
test on a shorter clip first
Common problems and fixes
The swapped face does not look like the person I uploaded Try:
using a sharper, better-lit source image
using a source face with a similar angle
avoiding side-profile source photos
choosing a frame where the target face is clearly visible
only choosing high quality faces to swap in Multi Face Swap (in the original video)
The output looks choppy or blurry Try:
shortening the source clip
using cleaner source footage
avoiding fast camera movement
checking whether your current plan limits output resolution in My Plan
The result looks distorted Try:
using a source face with a neutral expression
avoiding clips with rapid pose changes
testing with a shorter clip before committing to a longer render
The face swap fails Try:
confirming that a face is clearly visible
confirming that the uploaded file is supported
trying a shorter, simpler clip
re-uploading the source face image
retrying with a different input video
If the result completed but the quality is still poor
If the project completed successfully but the output is low quality, that is different from a technical failure. In that case, the most effective fix is usually improving:
source image quality
target clip clarity
lighting
face visibility
clip length
Contact support if
the project failed multiple times
credits did not return after an error
the result is clearly broken
the quality is dramatically worse than expected despite clear inputs
Include:
your project ID
the approximate clip length
whether the issue is failure or low quality
the tool page URL
what you expected versus what happened
