YouTube's built-in captions get the words roughly right. Fluen gets the punctuation, segmentation, and formatting right too.
In your Fluen Studio's workspace, click "Add New" and then "Import From Youtube". Add your Youtube URL.
Click continue to choose your video language, set your style guide, and select any other language you want your video to be translated into.
Click "Submit" and wait until your video has been processed. It usually takes a minute or two. Once ready, your caption language will be highlighted in blue, meaning it's ready to be edited. Click on it.
You can check the generated script and make any correction, if you want. When you're done, click on the "Export" button and choose "SubRip (.srt)" to download the caption file.
Log into Youtube, select "My Channel" from the left sidebar and then "Video Manager". Find the video and click the edit button next to it. In the dropdown menu that will appear, select "Subtitles and CC". This will open the subtitling interface: press the button "Add new subtitles" and select "Upload a file". Use the playback to review your subtitles once again, and click "Publish".

Fluen's context-aware AI translation doesn't just swap words. It re-segments every cue for the target language, respecting character-per-line limits and natural reading flow. Upload captions in one language, export in dozens.
Upload your video file to Fluen, and our AI generates accurate captions automatically. Review them in the built-in editor, then export as an SRT file. In YouTube Studio, go to your video's Subtitles section, click "Add language," then "Upload file" and select your SRT. Your professional captions will appear exactly as you reviewed them.
Yes, significantly. YouTube's auto-captions miss punctuation, break lines mid-word, ignore capitalization, and produce long, unreadable cue blocks. Fluen generates broadcast-quality captions with proper punctuation, smart segmentation at natural sentence boundaries, correct capitalization, and speaker change detection. The difference is immediately visible to your viewers.
Absolutely. Once your captions are generated and reviewed, translate them into 50+ languages with Fluen's AI translation engine. Each translation is context-aware and automatically re-segmented for the target language. Export a separate SRT for each language and upload them all to YouTube Studio.

YouTube accepts SRT (SubRip) and VTT (WebVTT) subtitle files. Fluen exports both formats. SRT is the most widely used and recommended for YouTube uploads. Simply download your SRT from Fluen and upload it in YouTube Studio under your video's Subtitles settings.
Most files are processed in minutes. A typical 10-minute YouTube video takes about 1–2 minutes to transcribe. Longer videos (60+ minutes) take 3–5 minutes. Processing time depends on file length, audio quality, and the AI engine selected. You'll be notified as soon as your captions are ready.
