THE EDITING BOTTLENECK

Manual editing should not take longer than creating the video.

You already did the research, wrote the story, and recorded the narration. The repetitive timeline work should not be the hardest part.

FROM SOURCE TO SCREEN

Five steps. One finished workflow.

TopicCut keeps every moving part connected, so a beginner can go from raw source to an organized final edit.

01

Import source videos

Add one or many long source videos. Every source stays connected to its timestamps, crop, SRT, and voiceovers.

02

Create the topic map

Import one or many SRT files—or paste a YouTube link to build editable topic timestamps from a timed transcript.

03

Build scenes automatically

Trim intros and endings, create random 8.1–11.9 second scenes, and let Autopilot reorder the sequence.

04

Add narration and music

Match voices to topic names, fit visuals to narration, mute source sound, and duck music under speech.

05

Preview and export

Review each topic or the merged timeline. Export one topic, every topic, or one combined MP4.
