Video editing with Flowblade

Video Editing With Flowblade

To install flowblade,

sudo apt install -y flowblade

To add a new video file to the project:

  1. Use the Add button to add the video file
  2. Drag the video file to the timeline sequence panel (as V1) at the bottom of the screen.

To speed up a segment of the video,

  1. Use i to add the Mark In marker at the start of the segment
  2. Use o to add the Mark Out marker at the end of the segment
  3. Right-click on the timeline sequence and select on the Open In Clip Monitor option
    1. This ensures that markers are added to the video
  4. Right-click on the video file and choose Render Slow/Fast Motion File
  5. In the pop-up dialog,
    1. Change the speed of the file
    2. Change the Render Range to Source Mark In to Mark Out
    3. Wait for a few seconds for the new video segment to be created
  6. Drag and drop the new segment onto an unused timeline sequence; e.g., V2
  7. Cut the original segment out of the V1 sequence
  8. Add the new segment into V1
  9. Once completed, use the Clear Mark button to clear all the marks
  10. It's generally useful to rename segments segregated by the cut function

To cut segment of the video,

  1. Set the Mark In and Mark Out markers on the timeline sequence to indicate segment to be cut
  2. Use the Move to Mark In and Move to Mark Out buttons to navigate to these markers
  3. Use x to set the cut lines on these two markers
  4. To delete the segment, use the Del key
  5. The segment can also be dragged and dropped to another sequence
    1. Turn off the audio and video on these new sequences to avoid interference with the main sequence, when playing the video
