Hardcode Subtitles into Video
An SRT file is a promise the platform can break: TikTok renders it one way, an embedded player another, and an ad placement might drop it entirely. Hardcoding ends that. Eliro burns your captions into the video pixels themselves—your font, your colors, your animation, rendered identically everywhere the file plays. No CC button to press, no sidecar file to lose.

Why Burned-In Beats a Caption File
Once captions are part of the pixels, compatibility stops being your problem
Pixel-Identical Everywhere
Burned-in captions can't be re-rendered, restyled, or hidden by a platform. What you export is exactly what plays on TikTok, Instagram, YouTube, email embeds, and paid placements.
Your Styling Survives the Upload
Closed captions get flattened into the platform's default look. Hardcoding preserves your exact font, outline, colors, and positioning—your captions stay part of your brand.
Animations That Can't Exist in SRT
Word-by-word highlights, bounce-ins, karaoke fills—effects no caption file format supports. They only work burned in, which is why creators hardcode.
On by Default for Every Viewer
Open captions don't depend on viewers finding a CC toggle. Sound-off scrollers, viewers in loud places, and deaf audiences all get the words automatically.
Burning In Captions, Start to Finish
Upload the Video
Any major format works—MP4, MOV, AVI, WebM. The AI transcribes the audio so there's no SRT to prepare first.
Style the Captions
Choose fonts, colors, outlines, position, and animation. This is the look that gets baked in, so everything is adjustable before the burn.
Burn and Export
Eliro renders the captions into the video frames and exports a single file with the subtitles permanently embedded.
Get the Burn-In Right the First Time
Proofread Before It's Permanent
Hardcoded means hardcoded—a typo burned into pixels means re-exporting the file. That's why Eliro puts a click-to-edit transcript in front of the burn step: fix names, terms, and punctuation while they're still just text.
Built for Feeds That Play on Mute
Short-form feeds autoplay silently, and a video without visible words gets swiped past. Burned-in captions are the one caption type no platform can fail to show—which is why nearly every viral clip you see uses them.
Finish the Video Before You Burn It
The burn-in is the last step. Run these first so the file you export is the final one.
Remove Filler Words
Clean the audio before captioning—otherwise every "um" gets transcribed and burned in too.
Auto Zoom & Pan
Add movement before the burn so captions and punch-ins are composed together.
Background Music
Mix your music bed first—hardcoded captions ride on top of the finished audio.
AI Video Editor
Make final trims and overlays in the editor, then send the locked cut to the burn step.
