You can save a single frame from the current preview by first moving the current preview position until the desired frame is visible in the preview, then doing one of the following:
- Select Sequence -> Player -> Snapshot from the menu and select a resolution to take a snapshot of the sequence preview at that resolution.
- Select Clip -> Player -> Snapshot from the menu and select a resolution to take a snapshot of the clip preview at that resolution.
- Press F11. This will take a snapshot of the sequence preview.
- Right click on the preview itself and choose Take Snapshot of Sequence. If you right clicked the clip preview, it will say Take Snapshot of Clip.
The frame will be saved to the folder specified in Options -> Disk -> Save snapshots to. It will also be added as an image clip to the current project.
Alternatively, to save all frames of a sequence as a series of images, see Image Sequence in Saving, Sharing, or Burning a Video.
