Tangerine review
If a video is ready and the site’s player wants WebVTT, the subtitle file can hold up the whole upload. Tangerine, from Leap Studio, can turn an existing SRT into a VTT copy on a Mac. It’s a paid app for Apple silicon Macs running macOS 13 or later.
Make a WebVTT copy from the finished SRT
If the captions are already timed in Kdenlive™, export the subtitle track as SRT. In Finder, start dragging that file, tap Shift and choose VTT from Tangerine’s conversion menu. It saves a new file beside the SRT, so the one from the edit stays available for later corrections.
Play the result on the page
I’d add the VTT to the video player on a preview page and turn the track on. Check the first line, a quick exchange and the last line. If the video has been trimmed since the SRT was made, fix the timing in the edit before converting it again. Make sure the captions also carry any sounds viewers need to follow the scene.
Anabel’s take
I’d use this when I already have captions I’m happy with and only need the file the web player expects. I’d watch a short stretch with the sound off before the page goes live.
