Key characteristics of CapCut Web's AI captions
- Quick subtitles generation
When you upload your video to AI captions, it picks up the audio and drops in the captions on the screen. You don't have to type each line or guess the timing. This gives you a solid starting point, especially for longer videos or when you're working under time pressure.
- Accurate subtitle translation
With CapCut Web, you can change the subtitles' language with one click. The translation lines up with the original timing, and the meaning stays close to what's being said. You can still check and edit if something needs adjusting, but most of the work's already done.
- Preset caption templates
The tool provides you with a full list of font styles, like glow, monoline, basic, or aesthetic. These are grouped by category, so it's easy to scroll through and find something that fits the tone of your video. You can also drag & resize the text on the screen using simple handles.
- Style captions with AI
You can use the "Style captions with AI" option to automatically change the caption style on your content. It goes through your video and picks a font style that blends well. This saves time when you're not sure what design works best.
- Advanced caption boost
The "Caption boost" option in CapCut Web adds emojis, text effects, sound tags, or stickers to the subtitles to improve their appearance. It's useful for casual videos, reactions, or anything meant to be fun and expressive.

Common subtitles format supported by online tools
- SRT
SRT or SubRip Subtitle is the most widely used format and works with platforms like YouTube, Facebook, and VLC Media Player. It includes the subtitle text along with start and end timecodes so the captions stay in sync with the video.
- TXT
TXT files are plain text files that don't include timing. That's why they're usually used for transcripts rather than timed subtitles. You might use this format when you just need the spoken content written out, such as for documentation, scripts, or blog posts tied to a video.
- VTT
VTT stands for WebVTT (Web Video Text Tracks). It's similar to SRT but includes extra features like styling and positioning. Vimeo and HTML5 video players use it because it gives a bit more control over how the subtitles appear on screen.
- SUB
SUB files come from older subtitle tools and often work alongside a separate IDX file. These formats show up more on DVD rips or older movie files. They support basic timing and subtitle data, but you usually need both the SUB and IDX files for the subtitles to show correctly.
- ASS
ASS or Advanced SubStation Alpha is a subtitle format with extra styling options, which include different fonts, colors, sizes, and exact screen placement. People often use it for anime or fan-subbed content where timing and visual style matter a lot.

- What's the best free subtitle converter for SRT files?
A good SRT converter should let you upload, edit, and export your subtitles easily, especially if you're working with common formats or switching between tools.
