CutConvert génère le bloc GSI et les blocs TTI binaires en codage ISO 6937, qui représente correctement les accents du français par caractères combinés. La sortie est vérifiée image par image contre la chaîne de référence de l’IRT allemand.

Fichier SRT et Sous-titres EBU-STL, expliqués
L’EBU-STL (Tech 3264) est le format d’échange de sous-titres du broadcast européen : un fichier binaire avec un bloc GSI de métadonnées et des blocs TTI de 128 octets par sous-titre. Il reste exigé à la livraison par des diffuseurs de toute l’Europe, France comprise. Attention : à ne pas confondre avec les fichiers .stl d’impression 3D — le convertisseur les détecte et les rejette automatiquement.
Générez des fichiers .stl EBU (Tech 3264) pour la livraison broadcast européenne à partir de sous-titres SRT. C'est gratuit pour commencer, chiffré en transit, et un lot entier est converti en un seul ZIP — connectez-vous pour les gros fichiers et les volumes importants.
Questions fréquentes sur SRT en STL
Qu’est-ce qu’un fichier EBU-STL ?
Le format binaire de sous-titres de l’UER/EBU (spécification Tech 3264) : un bloc GSI de métadonnées suivi de blocs TTI de 128 octets par sous-titre, avec timecode à 25 i/s. C’est le format de livraison historique, toujours en vigueur, du broadcast européen.
Les accents et caractères spéciaux sont-ils conservés ?
Oui — l’EBU-STL utilise le codage ISO 6937, qui représente à, â, ç, é, è, ê, ë, î, ï, ô, ù, û et les autres caractères latins accentués par des séquences d’accents combinés. Le convertisseur gère ce codage automatiquement.
Quelle cadence utilise le STL généré ?
25 i/s (STL25.01), le standard du broadcast européen. Si votre SRT provient d’un master à une autre cadence, vérifiez les temps contre le master de livraison.
Est-ce gratuit ?
La conversion broadcast est gratuite à l’essai avec de petits fichiers (jusqu’à 100 Ko). Pour les fichiers complets, les forfaits démarrent à 9 $/mois.

Why editors trust it
Free to start
Convert everyday batches for free. Create an account when you need large, high-volume jobs.
Batch in, one ZIP out
Convert a batch within your allowance and download a single ZIP, or one file if that is all you need.
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.
Private by design
Files are converted in your browser. Queued files can be saved locally to restore your job after checkout. Conversion metadata helps us diagnose errors; file contents are not uploaded.
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.
