Checksub vs VideoLocalize

Checksub provides AI-powered subtitles, dubbing, and voice-over for videos through web, API, and extension platforms. It can create subtitles automatically or synchronize subtitles from a script, and it offers subtitle translation in 200 languages. Its dubbing replaces the original voice while keeping the audio background; Checksub also says users can substitute a cloned voice in 30 languages. The online editor lets users revise and regenerate sentences after subtitle or dubbing generation. Subtitles can be burned into exported videos with animated styles, including karaoke animation. Translated-video publishing to YouTube is supported, and the Starter plan connects one channel. Listed integrations include YouTube, Twitch, Google Drive, Adobe Premiere Pro, DaVinci Resolve, and Final Cut Pro. Credit use varies by task: one credit minute per video minute for subtitles, three for dubbing, and five for lip-sync. The service has a free plan and free trial. Checksub was founded in 2017 and is headquartered in France.

VideoLocalize is a cloud-based video translation management system for coordinating translation timing, subtitles, voice-over, and audio/video synchronization. Word-count-per-minute guidance helps translators fit translated scripts within the original video's timeframe. Its karaoke-style voice-over method helps talent match the original speaker's timing, while collaboration features support communication and sentence-level tracking of translation and voice-over work. VideoLocalize offers auto-captioning and subtitle translation. The platform runs online without software installation, and voice talent can record in a browser. MP4 and AVI are among its supported video formats; SRT is the currently supported subtitle format. Users can download completed audio and video after synchronization. Logged-in users can save videos to Dropbox through Subtitle Burner, and the maker lists an API for integrating translation and dubbing into another product. The free plan includes one account, two jobs, videos up to four minutes, 1 GB storage, 10 minutes of machine transcription, and 30 minutes of auto-synchronization. Some features require a paid plan.
