Captioning & subtitling

Vertical Video Subtitles (9:16, UI-Safe)

Short-form vertical video lives or dies on watch-through, and a caption buried under the interface costs you the view. I caption 9:16 video so every line sits clear of the Like, Share and native-caption UI, styled to match your channel, and delivered as SRT, VTT or a ready-to-post burn-in, usually within 24 hours.

How it works

1

Scope and spec

You send the video and target profile. I confirm frame rate, timecode, caption style and the delivery formats you need.

2

Author

I time and write the captions or subtitles to the reading-speed, line-length and positioning rules for the target.

3

Encode and wrap

I produce the deliverables: SCC, MXF OP1A embed, SMPTE ST 2052-1 or DCP XML, plus a burned-in preview.

4

QC and deliver

I decode the result independently with caption-inspector, fix anything that drifts, and deliver with a report.

Three steps, done in a day

No long back-and-forth. Send, pick, receive.

1. Send the link

Drop a video link or upload the file, and tell me the platform.

2. Pick a caption style

Choose an on-trend style preset, or send a reference to match.

3. Get the file

Receive SRT, VTT or a styled burn-in, usually within 24 hours.

Quality promise: 100% of captions sit clear of the platform's Like, Share and native-caption UI, never covered.

Frequently asked questions

Will the captions be covered by the app buttons?

No. I place every line clear of the Like, Share and native-caption UI, so captions stay fully readable on YouTube, TikTok and Reels style layouts instead of hiding behind the interface.

How fast is delivery?

Usually within 24 hours for a single short-form video, with quick revisions in 2 to 4 hours. Monthly and volume packages keep a steady turnaround for a content schedule.

What does it cost?

From $2 per minute, with a per-video or monthly package on request. Send a link, tell me your volume and the style you want, and I send an exact quote.

What formats do I get?

SRT and WebVTT for platforms that read them, or a styled 9:16 burn-in MP4 ready to post. YouTube, TikTok and Reels map to SRT, VTT or burn-in.
