Watch videos

Playback of video stacks, with controls for review work (importing video requires FFmpeg setup). GIFs are treated as video too, and play with the same controls.

Playback controls

Play and pause, adjust volume and mute, and move along the seek bar.

Frame-by-frame

Move in small steps to check motion.

• Step backward / forward one frame — Check one frame at a time. Adjust the step size with “Step FPS”
• Fast forward / rewind — Move at 1.5x speed while you hold the button

Markers

Place a mark on the seek bar at a moment you want to revisit.

1. Add a marker, and set the time (in seconds) and color in “Marker Settings”
2. Click a marker to jump to it
3. Edit or delete markers when you no longer need them

Keep a frame

Use the current frame as-is.

• Set as Thumbnail — Make this frame the face of the stack
• Download Frame — Save this frame as an image
