Turn your images, video clips, voiceover, and script into a finished MP4 automatically.

BuildTuber Auto Edit 2.0 is a free Google Colab notebook that removes one of the most repetitive parts of faceless YouTube production: manually dragging, syncing, trimming, and animating dozens or even hundreds of assets on an editing timeline.

Just prepare:

• Your images and video clips in one continuous numbered sequence
• One final voiceover file
• Your script with one scene per line

Open the notebook, click Run All, wait for the Studio to load, then upload your assets.

The tool transcribes the voiceover, matches it against your script, calculates when each image or clip should appear, trims or repeats video clips to fit the narration, adds automatic Ken Burns zooms and transitions, builds the timeline, and renders the final MP4.

You can preview the finished video inside the tool and download it directly when the render is complete.

No manual timestamps.
No CapCut timeline dragging.
No software installation.
No render credits.

Everything runs inside your own Google Colab session.

Works best with English and other Latin-script languages.

This is the free final-assembly tool from BuildTuber. If you want to automate the steps before this too, including scene creation, image prompts, bulk image generation, voiceover generation, and asset organization, check out the full BuildTuber workflow.
