Subtitle Extraction · Detached Sidecars

Extract synced .ass & .srt subtitles from Twitch VODs

The Editor Bottleneck

Most clip tools burn low-resolution, hardcoded captions directly onto video pixels. When you want to style fonts, resize typography, or rebrand subtitles inside Premiere Pro or After Effects, you're trapped. PeakClip generates detached Advanced SubStation Alpha (.ass) and SubRip (.srt) subtitle sidecars timed to the exact frame, keeping your underlying video untouched.

Answers for Editors

Frequently Asked Questions

What is an .ass subtitle file and why is it better than burned-in text?

Advanced SubStation Alpha (.ass) is a rich subtitle format that stores text, styling codes, fonts, animations, and precise frame timings separately from the video. Unlike burned-in subtitles, you can edit words, recolor text, and swap fonts anytime without re-rendering the video.

Can I edit .ass subtitles in Adobe Premiere or DaVinci Resolve?

Yes. In Premiere Pro, you can import .srt or .ass sidecars and style them using Essential Graphics or dedicated subtitle plugins. In Resolve, subtitle tracks give you full keyframing and typography controls.

Does extracting subtitles require downloading the full Twitch VOD first?

No. PeakClip extracts only the audio data for your chosen timestamp range on cloud infrastructure, skipping the download of the rest of the stream.

What speech recognition model generates the Twitch subtitles?

PeakClip utilizes state-of-the-art Whisper models optimized for speech clarity, gamer banter, and background stream noise, outputting frame-synchronized timestamps.
