How will this script save me time?
If you want to manually render out different sections of the same comp in After Effects you would have to:
- Add your comp to the render queue
- Open up the render settings
- Change the Start time & End time to the correct value
- Go back into your comp and add the next section
- Repeat steps 1 - 4 for every different section you need
Not only that, you would have to repeat this process every single time you want to render those sections out.
