About Vidkiller
Vidkiller is a web-based service that automatically generates subtitles for videos and overlays them in various styles. Users upload a video file in MP4, MOV, or WebM format up to 100 MB and select from multiple caption styles such as karaoke, neon, glitch, or editorial. The tool uses speech recognition to detect spoken language and produce a transcript with word-level timestamps, ensuring accurate synchronization. After generation, users can review and edit the subtitles, adjusting text, timing, fonts, colors, and positioning before exporting. The output is a vertical video in 1080×1920 resolution, optimized for social media platforms like TikTok, Instagram Reels, and YouTube Shorts. No account creation or watermark is added to the final video.
