How to convert SRT to ITT

Convert SRT to ITT (iTunes Timed Text) online. CutConvert rewrites every SRT cue as SMPTE frame-based timecode in the .itt caption format Final Cut Pro and Apple delivery workflows accept.

  1. Add your SRT files

    Drag your .srt subtitle files onto the drop zone, or click to browse.

  2. Convert to ITT

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

  3. Download captions and report

    Download one ZIP containing the converted captions, original source, caption recovery data and conversion report.

SRT file and iTunes Timed Text, explained

iTunes Timed Text (.itt) is the TTML dialect Apple uses for caption delivery and the subtitle format Final Cut Pro imports natively. Unlike SRT, it times cues in SMPTE frames against an explicit frame rate. That is why a correct converter needs your project frame rate rather than just copying timestamps across.

Create iTunes Timed Text with your chosen frame rate and language, styled text and line breaks. Download captions with the original source, recovery data and a conversion report. 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 the subtitle format Final Cut Pro imports 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, 24 fps is used and a warning is added.

Will this import into Final Cut Pro?

Final Cut Pro supports ITT caption import. Our generated samples pass Apple’s ITT schema, but native Final Cut import has not been verified here. 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. Current guest usage and file limits appear above the converter. A free account removes the monthly cap for files within the free size limit; paid options support larger files and batches.

Made for editors

Whole timelines from Premiere, Final Cut and Avid with transitions, markers, titles, keyframes, levels, nests and bins; captions that keep their italics, colour, placement and speakers across SRT, VTT, ASS, TTML, iTT, SCC and STL, any of them in, any of them out; transcripts into Premiere with the words the engine timed. Frame rates and timecode handled the way post expects.

Questions, answered

Where are my files processed?

In your browser. The converter runs on your own machine and the file never leaves it; the site only records that a conversion happened. CutConvert never sees, stores, sells or shares your media.

Is it free? Do I need an account?

About an hour of footage per file is free, on every converter: 100 KB of subtitles or captions, 500 KB of Word transcript, 2 MB of transcript JSON, 1 MB of Resolve project, 5 MB of Final Cut XML, with Premiere projects and Avid AAF a little under the hour. CapCut projects are free up to 500 KB, a short edit, since their size follows how much is in the edit rather than its length. Guests get five conversions a month, a free account has no monthly cap within those sizes, and above that project-to-project transfers are $5 per file. Every other conversion is $3, including project files to captions, reports or cut lists, and captions or transcripts into an editor. Pro is $9 a month ($90 a year) for every file type up to 50 MB; Studio is $19 a month ($190 a year) for files up to 500 MB. Paid-file access lasts 24 hours.

What do I get when I convert multiple files?

Drop several files and you get back one ZIP archive containing every converted file. Convert a single file and you get that one file back, no ZIP. Tick extra formats under the output chips and the same ZIP carries every one of them, and a file counts as one conversion whatever it is written to.

Which formats are supported?

Timelines: Premiere .prproj, DaVinci Resolve .drp (as exported, or gzip- or Zstandard-wrapped), Avid AAF and Final Cut FCPXML in; FCP7 XML, FCPXML, Resolve .drp, CMX 3600 EDL and shot-list CSV out. A Premiere or Final Cut edit travels with its transitions, markers, titles, opacity and scale keyframes, clip volume, speed changes, nested sequences, bins, audio channel routing and each file's own frame rate, wherever the output has a place for them; an Avid AAF brings its transitions, markers, clip levels with their keyframes, muted tracks, nested stacks and each clip's own rate. Captions and transcripts, read and written: SRT, WebVTT, SBV, ASS, TTML, DFXP, iTT, SCC, MCC (a second 608 channel comes out as its own file), EBU-STL, Avid caption TXT, CapCut drafts of any size, timed CSV, Word, plain text, Whisper, WhisperX, AssemblyAI, Deepgram, Rev.ai and CapCut JSON, TwitchDownloader chat logs as a chat replay, Premiere transcript JSON and .prtranscript, Rev, Otter and Word-style transcripts, with italics, colour, placement and speakers kept where the output can hold them and measured word timing into Premiere. EDLs become event CSV reports. The capability table lists what every pair keeps.

Can I pick a frame rate?

Yes. For EDL and Avid caption output you can choose 23.976, 24, 25, 29.97, or 30 fps, or let CutConvert auto-detect it from your source.
