Jianying Auto Captions: How to Generate and Style Subtitles

Automatic captions are the feature most creators open Jianying for. The editor listens to the speech in your clip, builds a timed subtitle track on the timeline, and lets you restyle the whole track in a few taps. Done well, captions lift watch time on every platform, because most short videos are first seen with the sound off.

This guide explains the full caption workflow in the Jianying app: generating the track, correcting the words the recogniser gets wrong, splitting long lines, and styling text so it stays readable over busy footage. Every step was checked on a real Android phone during our review. If you are new to the app, start with Jianying official site for the verified facts, screenshots and download information, then come back to this guide.

Generate the caption track

Open your project, select the clip with speech, and find the text tools. Choose the automatic caption or speech recognition option and let the app process the audio. Processing happens fastest on a quiet, clear voice track, so record voiceovers away from fans, traffic and echo where you can. When the track appears, it sits on its own layer above your video on the timeline, already split into short timed blocks.

Play the whole video once with captions on before you edit anything. Recognition is strong on clear Mandarin and handles English speech well too, but names, slang and technical words are where errors cluster. Mark those spots as you watch, because fixing text is much faster than rebuilding timing.

Fix words, timing and line breaks

Tap any caption block to edit its text. Keep each block short, ideally one short phrase per screen, so viewers can read without pausing. If a sentence runs long, split the block at a natural pause and the timing divides with it. Drag block edges on the timeline when a caption starts early or lingers after the speaker stops. A caption that lands exactly on the first syllable feels professional, while one that trails by half a second looks careless.

Watch for homophones and product names, which recognisers replace with similar sounding common words. A quick pass with the script beside you catches these in minutes. For series content, keep a small glossary of your recurring names and terms, and check them the same way in every episode.

Style captions for small screens

Pick a bold, simple font and keep it consistent across your channel. Add a dark outline or a soft shadow so text survives bright backgrounds, and place captions in the lower third without covering faces or product details. Jianying lets you save a caption style, which keeps a whole series consistent with one tap per episode. Animate captions sparingly: a gentle pop on key words works, while constant motion makes reading harder.

Check contrast at phone size, not on the preview alone. Export a ten second test, watch it on the phone at arm's length, and confirm every word is easy to read. If any line fights the background, strengthen the outline rather than enlarging the text, which keeps the frame clean.

Export settings that keep captions sharp

Burn captions into the video when you publish to platforms that ignore subtitle files, so the text travels with the file everywhere. Export at 1080p or higher when the platform allows it, because compression softens small text first. If you upload to a platform with its own caption system, you can export a clean copy as well and add the platform captions separately, giving viewers a toggle while your burned in version covers shares and reposts.
