Export Accurate SRT Captions with TimeBolt Umcheck (No Extra Editor Needed)

 IF GREAT VIDEO STARTS WITH A CUT, IT ENDS WITH CAPTIONS.

Captions make your video accessible, boost SEO on YouTube, and keep silent scrollers engaged on social. With Umcheck AI credits in TimeBolt, you can generate timeline-accurate SRT files directly from your edits. Every silence removed. Every filler word cut. Captions locked to your final timeline.

What Are SRT Captions?

SRT (SubRip Subtitle) files are plain-text subtitle files with timecodes for each line of dialogue. Example: 

Unlike a raw transcript, which is just text, an SRT file syncs exactly to your video timeline. That means captions reflect your edits—cuts, pauses, or rearranged clips—so viewers always see the right words at the right moment.

Why Do Tools Charge for SRT?

You might wonder why this isn’t free when Whisper can transcribe. Whisper is open source, but it processes audio in 30-second chunks. That creates drift, missing punctuation, and timestamps that often need cleanup.

TimeBolt uses Amazon AWS Transcribe at the word level. That means captions align down to the millisecond. It is the same enterprise-grade service other editors lock behind premium tiers. Everyone pays for word-token transcripts. 

Paid vs Free SRT in CapCut

To show the difference between Paid and Free SRTs, here was our test setup:

Same 75-second clip. Same edit. Imported two ways in CapCut:

• Free auto captions inside CapCut

• TimeBolt SRT exported with Umcheck AI (Amazon AWS Transcriptions)

TimeBolt Paid SRT vs CapCut Free Captions 

Results

Why this matters

• Readability: Shorter, punctuated lines are easier to read and scan.

• Edit workload: Free captions arrive as long, unpunctuated blocks that need manual fixing. TimeBolt SRT drops in clean.

• Timing precision: More, shorter blocks reflect where sentences actually start and stop, which keeps captions aligned with your cuts.

How to reproduce

1. Edit in TimeBolt.

2. Run Umcheck AI and export SRT.

3. In CapCut, import the same video twice.

4. Version A: use CapCut’s free auto captions.

5. Version B: import the TimeBolt SRT.

6. Compare block count, punctuation, and average block length.

Umcheck: The Engine Behind TimeBolt Captions

• Custom filler word detection

• Reverse-timeline waste analysis that verifies cuts

TimeBolt combines waveform analysis with AWS transcription to deliver both speed and accuracy. Unlike edit-by-text tools, the workflow is consistent, precise, and built for creators who want to publish faster.
