Como converter STL para SRT

Converta um arquivo EBU-STL em um SRT editável. O CutConvert lê o bloco GSI, decodifica os blocos TTI — incluindo cadeias de extensão e caracteres acentuados ISO 6937 — e gera um SRT limpo com os tempos originais, verificado quadro a quadro contra a cadeia de referência do IRT.

  1. Adicione seus arquivos STL

    Arraste seus arquivos .stl para a área de upload ou clique para selecionar.

  2. Converta STL para SRT

    Clique em Converter. O decodificador lê a taxa de quadros do cabeçalho e reconstrói cada legenda com os acentos corretos.

  3. Baixe o .srt

    Baixe legendas SRT prontas para editar, traduzir ou publicar em qualquer plataforma.

Legendas EBU-STL e Legendas SRT, explicados

Arquivos EBU-STL vêm de acervos de emissoras europeias e entregas antigas — e ferramentas modernas raramente os abrem. Decodificá-los para SRT recupera o texto e os tempos para fluxos atuais: streaming, tradução ou reedição. Se o seu .stl for na verdade um modelo de impressão 3D, o conversor detecta e avisa em vez de produzir lixo.

Decodifique arquivos .stl EBU broadcast em legendas SRT limpas e editáveis. É grátis para começar, criptografado em trânsito e converte um lote inteiro em um único ZIP — faça login quando precisar de trabalhos grandes e de alto volume.

Perguntas frequentes sobre STL para SRT

Por que meu arquivo .stl não abre em lugar nenhum?

EBU-STL é um formato binário broadcast que as ferramentas modernas quase nunca implementam. Converter para SRT é o caminho prático — e se o arquivo for na verdade um .stl de impressão 3D (mesmo sufixo, formato diferente), o conversor detecta e avisa.

Os acentos são decodificados corretamente?

Sim — a codificação ISO 6937 do formato, com suas sequências de acento combinado, é decodificada para Unicode correto: á, é, ã, õ, ç e os demais caracteres saem intactos.

Qual taxa de quadros é usada na decodificação?

A declarada no cabeçalho GSI do próprio arquivo (25 fps na prática europeia comum), então os tempos do SRT correspondem exatamente ao master original.

É grátis?

Grátis para testar com arquivos pequenos (até 100 KB). Para arquivos completos, os planos começam em US$ 9/mês.

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.
