C – In order to add a toolbox, a new window needs to be created: drag the upper right corner of the Video Sequence Editor (the video preview) to the left. A copy of the same window will be created.
By dragging the same corner back to the right (on the new window) the box will disappear.

Set up the Rendering Options

Use the following values to have a correctly encoded video.

  • Framerate: we highly recommend to use a framerate of 30 or 60 (60 requires more performance). To avoid lag and glitches all the footage of a project should have the same amount of fps
  • Output: FFmpeg
  • Container: Quicktime
  • Codec: H264
  • Keyframe Interval: 5
  • Audio Codec: AAC

Once the right values are set up we just need to:

A – Import the footage (simply drag and drop from the folder to the timeline).
B – Set a start and an end frame.
C – Set output folder and file name.
D – Click on Animate to start the render.
