To add a new video file to the project:
- Use the
Add
button to add the video file - Drag the video file to the timeline sequence panel (as
V1

To speed up a segment of the video,
- Use
i
to add the Mark In marker at the start of the segment - Use
o
to add the Mark Out marker at the end of the segment - Right-click on the timeline sequence and select on the Open In Clip Monitor option
- This ensures that markers are added to the video
- Right-click on the video file and choose Render Slow/Fast Motion File
- In the pop-up dialog,
- Change the speed of the file
- Change the Render Range to Source Mark In to Mark Out
- Wait for a few seconds for the new video segment to be created
- Drag and drop the new segment onto an unused timeline sequence; e.g.,
V2
- Cut the original segment out of the
V1
sequence - Add the new segment into
V1
- Once completed, use the Clear Mark button to clear all the marks
- It's generally useful to rename segments segregated by the cut function
To cut segment of the video,
- Set the Mark In and Mark Out markers on the timeline sequence to indicate segment to be cut
- Use the Move to Mark In and Move to Mark Out buttons to navigate to these markers
- Use
x
to set the cut lines on these two markers - To delete the segment, use the
Del
key - The segment can also be dragged and dropped to another sequence
- Turn off the audio and video on these new sequences to avoid interference with the main sequence, when playing the video
