How to add word-by-word highlighted subtitles (karaoke-style) to my automated video pipeline?
https://gist.github.com/8ullyMaguire/923eb7da24fc273ac12ba88932fa984e
I’ve built a fully automated bilingual video pipeline (EN/ES) that takes YouTube links, EPUBs, or text files and produces analysis videos with TTS audio, static background renders, and cross-platform publishing (PeerTube, Bluesky, Mastodon, PieFed). Uses ffmpeg, edge-tts, ImageMagick, and Python.
One thing I haven’t cracked yet is adding those popular subtitle effects where each word highlights in sync as it’s spoken — bold white text with the current word glowing in yellow/red, appearing word-by-word with the audio.
My pipeline already has the TTS audio and full script text, so timing info should be extractable. Looking for:
Also happy for any other feedback on the pipeline approach — things you’d add, change, or pitfalls.
Thanks!
I was just experimenting with Audacity 4.0 Beta 2. It's an impressive upgrade. The GUI is much improved over Audacity 3.x. I added some built-in real-time effects to the track. I was able to change the output to pipe it through the Easy Effects app, which I have configured to simulate Dolby Atmos. I was running it as AppImage without issue on Fedora 44 KDE Plasma Linux.

This last year gave me the great opportunity to learn video editing, effects and other tricks alongside my management responsibilities and other duties. During this trial by fire, I picked up some fun trade lingo — things like the shy button, subharmonic whooshes, ripple trims, hairy armpits, goat bleats, and my personal favorite, the Wichita Watusi.
I think at least one of them has potential outside the editing suites — “All right, who let out the subharmonic whoosh?”
