How to convert SRT to ITT

    Choose your timeline frame rate and caption language in Delivery settings, then convert. Timing changes are listed in the report.

SRT file and iTunes Timed Text, explained

iTunes Timed Text (.itt) is the TTML dialect Apple uses for caption delivery. Final Cut Pro imports it natively. Unlike SRT, ITT times cues in SMPTE frames against an explicit frame rate. So a correct converter needs your project frame rate and does more than copy timestamps across.

Convert SRT to iTunes Timed Text at the frame rate and language you pick. Styling and line breaks carry over. It is free to start, encrypted in transit, and converts a whole batch into one ZIP — sign in when you need large, high-volume jobs.

SRT to ITT FAQ

What is an ITT file?

iTunes Timed Text is the caption format Apple uses for iTunes/Apple TV delivery, and Final Cut Pro imports it natively. It is a TTML dialect with SMPTE frame-based timing and an explicit frame rate.

Why does the converter ask about frame rate?

ITT times cues in frames, not milliseconds, so the same subtitle lands on a different frame at 23.976 than at 25. Set the frame rate to match your timeline. If you leave it on auto, the converter uses 24 fps and adds a warning.

Will this import into Final Cut Pro?

Final Cut Pro supports ITT caption import. Our generated samples pass Apple's ITT schema, but we haven't confirmed native Final Cut import. Match your timeline frame rate and delivery language, import the extracted .itt file and review the captions.

Can I convert several SRT files at once?

Yes. Drop a batch and download one ZIP. Guests get 5 conversions a month, up to 100 KB per file. A free account has no monthly cap within the free size caps and converts up to 100 files per batch. Pro is $9 a month for 100 conversions of files up to 50 MB.

Questions, answered

Where are my files processed?

In your browser. The file never leaves your computer, and CutConvert only records that a conversion happened. We never see, store, sell or share your media.

Files up to about an hour of footage convert free on every converter. CapCut projects are free up to 500 KB. Guests get five conversions a month; a free account has no monthly cap within the free size caps. Bigger files are $3 each, or $5 for a project conversion from one program to another.
