What each AI video model's release notes say changed

Editing existing video: AI model release notes

25 entries on editing existing video from 11 of the 17 lines, 24 of them dated 13 September 2024 to 6 August 2026. The table lists each with its line and version; the chart counts them per line. As of 2026-09-25.

1Reading the notes

Editing notes cover changing video that already exists instead of generating anew. Runway's Video to Video restyled uploaded clips from September 2024, Firefly's Generative Extend lengthened existing footage in Premiere Pro from October 2024, and its Aleph models in 2025 and 2026 make editing the model's main job. Luma's Modify tools, Wan 2.1 VACE and Wan 2.7 video edit, LTX's retake, PixVerse's restyle and modify, HappyHorse's edit model and Sora's edits endpoint all follow, some changing a region and some the whole clip.
