Replace the asset URLs in the JSON with your own files and adjust text, timing or effects on each clip. To generate many variations from data, turn the values you change into merge fields ({{ PLACEHOLDER }}) and pass a merge array with each request.
Yes. This template renders 1280×720 by default. Set output.resolution to "1080" or output.size to a larger 16:9 size in the JSON; the layout scales with it.
Yes. The template uses 7 images; replace each image asset's src with a public URL of your own file (JPG, PNG or WebP). Keep the timing and effects, or adjust them per clip.
Yes. The soundtrack is one audio URL in the JSON; point it at your own track (MP3 or WAV), or delete it for a silent render. Volume and fade effects are set on the same object.
