RenderCut
Auto-captioning and B-roll tool that turns raw video or audio into short-form content with synced subtitles for TikTok and Reels.
What it does
RenderCut is a short-form video editing tool that auto-generates synced captions, adds B-roll footage, GIFs, and emoji reactions, and can build a fully captioned video from an audio file alone. Users upload a video or audio clip, pick a caption style and brand template, then export for platforms like TikTok, Reels, and YouTube. A free plan allows a limited number of videos before requiring a paid subscription.
