Alt +.

2.From the Options menu, choose Video, and then choose Number Frames. A check mark appears next to this option on the menu when the feature is enabled, and a small box with a number appears at the bottom of each frame. The small black arrow marks the exact position of the frame.

Frame number

3.Using the data window’s zoom ratio controls, zoom in/out on the waveform several times and observe the numbering of the video frames.

Tip: Select a frame number format by choosing Preferences from the Options menu and selecting an option from the Frame numbering on thumbnails drop-down list on the Video tab.
