Edit, cut, or caption a video with AI help

− Credits burn fast and clips are limited to roughly 10 seconds per generation.

+ Eye-contact correction and lip-synced dubbing work well on phone-shot talking-head video.
− The subscription is expensive relative to CapCut and many effects feel gimmicky.

+ The most capable free editor for short-form, with TikTok-native templates and captions.
− Features keep migrating behind Pro, and its ByteDance ownership raises data and availability concerns in some regions.

+ Strong team collaboration and brand kit features for a browser editor.
− Exports are watermarked and capped at 720p on the free plan.

+ Deleting a word from the transcript deletes it from the audio, and Studio Sound removes room echo and noise in one click.
− Studio Sound can make voices sound processed, and the desktop app is heavy on large projects.

+ Produces a complete narrated explainer from a single prompt using its stock library.
− Output looks like a stock-footage montage and the free plan is heavily watermarked.

+ Sora 2 generates synchronized audio and dialogue with its video and the cameo feature inserts real people consistently.
− Heavy content restrictions, watermarks on free output and generations fail or queue at peak times.

+ Manages a whole project (characters, scenes, shot list) rather than one clip at a time.
− Per-shot quality is below Veo/Kling and the full pipeline eats credits quickly.

+ Accurate auto-subtitles and a broad toolset without installing anything.
− Browser rendering is slow for long projects and the free plan watermarks exports.

+ The standard for restoring old or low-resolution footage to 4K with slow-motion interpolation.
− Very slow renders without a high-end GPU and the price is steep for hobbyists.
