Assemble a recorded demo and handle its CapCut export with Codex
I recorded the light-bulb experiment in several clips and asked Codex to help finish the video. I wanted the full recorded sequence preserved. Once that was clear, it assembled the clips in order, kept every spoken word and the full frame, and made a vertical export with clean joins.
We also worked in the open CapCut project using computer use. Codex inspected the HDR settings and the voice-enhancement processing around the switch between camera and screen footage. The color pass still needed my correction. I made that adjustment and had it leave my grade alone for the export.
Codex then operated the export controls, checked the resulting file’s dimensions, frame rate, color space, and audio, and uploaded it to the TikTok Studio composer without posting. The useful division of work was having the agent assemble, inspect, export, and stage the video while I made the final visual call.
# Finish and verify an existing video
Adapted from this workflow; not the original transcript.
Inspect the video clips or open editor project I provide. Preserve the recorded order, spoken content, and framing unless I explicitly ask for cuts. Identify any HDR/SDR mismatch and audio processing that may affect the result. Show me a representative section before applying changes throughout the timeline.
Preserve any corrections I have made. Once the edit is approved, export for the destination I specify and inspect the actual file: dimensions, duration, frame rate, color space, video codec, and audio. Report what the file contains, not only the settings you selected.
Leave publishing to me. If I authorize an upload, stop in the destination composer before posting.
