Smartcat reads 80+ file formats. These media formats each have their own page:
The list goes further: 16 video formats including AVI, MKV and WMV, plus audio such as M4A, AAC, OGG, FLAC and WMA. WebM is the main exception. See every supported format.
Popular language pairs for video and audio content:
Compare tools on format coverage, shared terminology across formats, an editor for timing, a human review option, security and how usage is billed.
Smartcat fits teams that translate video, audio and documents together and want one glossary and one vendor. Teams that only caption a few clips a year may need less.
Smartcat has no free-forever plan, but you can test it free for 15 days with 15,000 Smartwords, no credit card.
Use the trial to run a video, an audio recording and a subtitle file through the same project, so you can compare outputs before you talk to procurement.
In 2026, 92% of words translated by Smartcat AI for paying customers were accepted without a single human edit.
For media, the transcript sets the ceiling. Clear audio transcribes well; music, crosstalk and accents need a transcript check, which Smartcat lets you do once before every language is generated.
Smartcat is SOC 2 Type II compliant, with encryption in transit and at rest, isolated workspaces and role-based access. SSO through Azure AD, Okta and ADFS is available on higher tiers.
On written request, your content is deleted or returned within 30 days.
A stack of separate tools: a captioning app, a dubbing studio and a CAT tool for documents. That works, but terminology and vendors multiply with each tool.
One honest gap: Smartcat does not accept WebM files, so convert them first, and AI dubbing is time-matched rather than lip-synced.
Video: MP4, MOV, AVI, MKV, M4V, WMV, MPEG and other containers, 16 in total. Audio: MP3, M4A, AAC, OGG, FLAC, WMA and MP2. Subtitles: SRT and VTT.
The same workspace also takes documents, presentations and other files, 80+ formats in all.
Usage is counted in Smartwords and metered by transcript word count, not by minutes. A long video with little speech costs less than a short, dense one.
AI dubbing uses 10 Smartwords per source word. Plan details are on the pricing page.
Yes. Upload the recording and Smartcat produces a timed, speaker-labelled transcript, then translates it.
You can export a translated document, SRT or VTT subtitles for a podcast player or video, or an AI voice track in one of the 35 voice locales.
Yes. Upload an SRT or VTT file on its own, or alongside a video with the same file name. In that case Smartcat links the two and skips transcription.
The video then serves as a reference, so reviewers check each translated line against the picture.
Yes. Video, audio and subtitle files are part of the same 80+ format list as Word, PowerPoint, PDF and web content.
That matters for consistency: a training course, its slide deck and its video can share one glossary and translation memory instead of three vendors' versions.
Plans include unlimited users. Admins assign roles, so marketers, trainers and reviewers see only the projects they need.
You can also bring in freelance linguists or agencies from the Smartcat Marketplace, or invite your existing vendors into the same project.
No. Media translation works from spoken audio and subtitle files. Titles, lower thirds and text inside slides stay in the source language.
For slide-heavy videos, translate the deck in Smartcat first and re-record, or edit the source project in your video tool.
