Using SRT on YouTube & TikTok

YouTube

Adding captions to a YouTube video

1. Upload your video to YouTube Studio
2. Go to Subtitles in the left sidebar
3. Click Add Language → select your language
4. Click Add → choose Upload file
5. Select your .srt file from VocalLab
6. YouTube will sync the captions to your video automatically

Auto-translate

Once you upload an SRT, YouTube can auto-translate it to other languages for international audiences.

TikTok

TikTok doesn't support SRT file upload directly, but you can use the captions in two ways:

Option 1 — Burn captions into the video (recommended)

Use a video editor like CapCut (free):

1. Import your video and audio into CapCut
2. Go to Text → Auto Captions → or Import SRT
3. Style your captions (font, colour, position)
4. Export and upload to TikTok

Option 2 — TikTok auto-captions

Upload your video to TikTok → enable Auto Captions in the caption settings. TikTok will generate its own captions (less accurate than your SRT but works).

CapCut workflow (TikTok & Reels)

1. Import video + VocalLab MP3 audio
2. Text → Import SRT
3. Select your .srt file
4. Captions appear word-by-word synced to audio
5. Style with TikTok-friendly fonts and colours
6. Export at 1080×1920 for vertical video
