How to Assemble Frames into a Video with ChatGPT

Assemble Frames into a Video with ChatGPT and ToolRouter. Compile a sequence of images into a smooth video with controlled timing, transitions, and audio.

Short Film Maker icon
Short Film Maker

Share your sequence and ChatGPT will produce the assembled video with a documented production spec. This is well-suited when the assembled video is one step in a larger production pipeline that needs recorded decisions for future revisions.

Steps

Once connected (see setup above), use the Short Film Maker tool:

  1. Share the ordered image set, total duration target, and any platform or audience constraints.
  2. Ask ChatGPT to run `short-film-maker` with `frames_to_video` to assemble the sequence.
  3. Request a production spec covering frame timing, transition choices, audio, and total duration.
  4. Attach the clip and spec to your production record for revision reference.

Example Prompt

Try this with ChatGPT using the Short Film Maker tool
Use short-film-maker with frames_to_video to turn these 12 storyboard frames into a 30-second animatic. Hold each frame for 2.5 seconds, clean cuts between panels, ambient thriller music. After generating, produce a production spec: frame count, total duration, transition type, audio description.

Tips

  • Document the timing spec after generation so any revision request has a clear baseline to work from.
  • Have ChatGPT note which frames were given more or less hold time if the pacing was uneven.
  • Ask for alternative timing suggestions before generating — ChatGPT can often identify a stronger pacing strategy for the narrative.
