Resolution / Draft to final
Watch as an animation →Check quickly at a low resolution, then make only the cuts that pass at the final resolution, to save credits and time.
The draft stage of every AI video, and contests or ads with a set delivery spec.
Edit with the 480p preview to lock the cut points, captions, and sound, then run the same ffmpeg assembly command again with only the resolution changed to 1080p. Set the delivery resolution (16:9 1920×1080, 9:16 1080×1920) at the generation stage, and don't count on upscaling.
Draft first: generate every shot at the lowest draft resolution, assemble the whole edit, and regenerate only the approved shots at 1080p with the same prompt and start frame. Make a light 480p preview of any assembled cut: ffmpeg -i final.mp4 -vf scale=-2:480 -c:v libx264 -crf 20 -c:a aac out.mp4
