Importing a PNG sequence in After Effects

Import the rendered frames as one sequence so After Effects plays them as a clip.

Import the sequence

1. In After Effects, choose File → Import → File.
2. Select the first numbered PNG in the rendered folder.
3. Enable the image-sequence option and import.
4. Set the interpreted frame rate to the frame rate used in Rotato.
5. Add the sequence to your composition.

Check alpha and timing

Place a colored layer underneath to confirm transparency. Check the sequence duration: the same number of frames plays for different durations at different frame rates.

A PNG sequence contains no audio. Import any soundtrack separately.
