Candidate frames
9 candidates: the frame at 00:14 is the sharpest with a face fully visible; the 00:32 frame is brighter but shows motion blur on the hands.
How the Video Cover Frame Picker works
- Add the video and choose how candidates are sampled.
- Compare the shortlist for sharpness and whether a face is turned toward the camera.
- Export the winner at full frame size and crop it for the platform afterwards.
FAQ
What makes a good cover frame?
A sharp subject, a face if there is one, and enough empty space for a title overlay. Mid-motion frames look fine in a timeline and terrible as a still.
Why is the frame blurrier than the video looks?
Motion blur is invisible at 30 frames a second and obvious in a single still. Prefer frames where the subject has paused.
Is the video uploaded?
No. Frames are decoded in the page.
