Not sure what you want or going with this.
Drop your video into the video time line
Place the cursor onto the time scale line (the one above the video line that has all the numbers on it) the cursor will turn into a clock with a left and right arrow on it.
HOLD down the left mouse and drag the cursor to the right of the screen. As you drag it, the time scale will change. Repeat the process until the time scale does not expand. The time scale line will display 00:00:00:00 which is hours:minutes:seconds:frames. the next numerical display is 00:00:00:04 ( oh by the way I am in Australia and we use the Pal system – 25 frames per second – your display may differ)between the first set of numbers and the next displayed are black vertical lines, each vertical line represents “a frame”.
If you place the scrubber on a frame line and use the cut tool, then go to the next frame with the scrubber and use the cut tool you have just marked a frame. highlight the frame by clicking on it, press “delete” and the frame is deleted.
You have just performed a frame edit.
