Oryn SDK reference workload
Create and style captions for your videos.
Your video, audio, transcript, and subtitle file stay on this computer. Review automatic captions before using them.
Your video queue
Review each. Render together.
1. Create subtitles for the queue. 2. Open each video, check its captions, and mark it reviewed. 3. Render all and download one ZIP.
Caption design, animation, and the optional ending apply to every video. Your edits and rendered videos stay here while you switch between them. Keep this page open.
Generated result
Edit timed cues
Edit caption text and timing / save subtitles
SubRip preview
In CapCut Desktop or Web, open Captions and import the saved SRT. Direct subtitle-file import on CapCut Mobile is not claimed.
Render video with captions
Create a new video with captions permanently drawn over the picture and the original audio included. Everything stays local. You can import the result into CapCut; captions will be part of the image, not editable text.
Caption studio
Make it yours.
Drag the preview to reposition captions, or use the position controls.
Design applies to all captions. Size scales with the video. Settings stay in this browser; Reset design restores the default.
Finishing touch
Add an ending
Finish with your own video or an animated end card.
The full clip is appended and fitted inside your source video's frame.
The transition blends the final source frame into the start of the ending. Your source plays in full. Short clips use a shorter transition.
Word highlighting requires individual word timings for every caption. SRT has only whole-caption times. Generate subtitles here and render directly, or save/reopen the timing JSON to keep word timings. You can switch tabs while rendering; keep this page open until it finishes. Up to 30 minutes total, 1920 × 1080 at 30 fps (aspect ratio preserved), and 256 MB output. MP4 when supported; otherwise WebM.
