About TTML
TTML (Timed Text Markup Language, also seen as DFXP and the IMSC1 profile) is the W3C XML caption standard used across OTT streaming and broadcast delivery. It expresses styling — italics, bold, underline and colour — and text positioning via tts: attributes. Parsing TTML/IMSC/DFXP is a CueForge Pro feature; validate any export against your platform’s current spec before delivery.
About SRT
SubRip (.srt) is the most widely supported subtitle format: numbered cues with start and end timecodes plus plain text, and basic inline tags for italics, bold, underline and font colour. It carries no positioning or advanced styling, which makes it the universal lowest-common-denominator that almost every editor and player accepts.
Frequently asked questions
Is converting TTML to SRT free?
Reading TTML (a broadcast format) is a CueForge Pro feature, so this conversion needs Pro — but there is a 7-day free trial, and you won't be charged until it ends. Exporting to SRT and the other core formats (VTT, SBV, ASS) is always free.
Do I have to upload my file?
No — everything is converted in your browser; your file never leaves your device.
Will my formatting be preserved converting TTML to SRT?
Italics, Bold, Underline and Font colour carry across into SRT. Positioning cannot be expressed in SRT and is dropped (CueForge shows you exactly what is lost before you convert).
