BurnKit burns animated, per-word-timed captions directly onto a video, and ClipKit reframes a long video into a vertical highlight clip — both in real time, at full quality. Real, shipped, running on every export today. Two years of studying how creators actually edit went into building them, grounded in our own background running content brands, not a feature we bolted on to look impressive.
Most caption and clip tools make you wait — a slow render every time you want to burn on a caption or cut a highlight — and the output rarely matches what you saw in the editor.
A caption track that takes a minute to render kills the editing flow. So does a highlight clip that reframes slightly differently every time. We set out to make both finish in seconds and land pixel-for-pixel the way the preview showed — every time.
That standard — instant, and identical to preview — is the entire reason BurnKit and ClipKit exist.
We tried the standard route first — the stock video-editing libraries most apps reach for. They broke down on real devices in ways that never showed up in a demo. Rather than ship something that only worked on the test phone, we built our own rendering pipeline from the ground up.
That decision is the entire reason BurnKit and ClipKit exist as real, hardened, in-house technology today — not a wrapper around someone else's SDK.
Not licensed, not a wrapper around someone else's SDK. Both live on Android today — BurnKit for iOS is coming soon.
Burns real, per-word-timed animated captions directly onto your video, in real time. Supports all 6 of Cinematic Pro's rendering mechanics — recolor, phrase marker, box, word-box, glass-pill, and reveal-blur — including gradient and glow text and per-word cursive font swaps, pixel-matched against the editor preview.
Turns a long landscape video into a vertical highlight clip — cropping and panning to keep the speaker's face in frame with automatic face tracking, then trimming and re-encoding to a ready-to-post clip at full quality.
The details of the pipeline are ours — what matters to you is what it means in practice.
Captions burn in and clips export in seconds, not minutes — see the exact numbers below.
Renders through a real hardware-accelerated video encoder — no compression shortcuts, no visible quality loss.
All 38 caption styles and every rendering mechanic are supported — not a curated handful that happen to work.
What you see in the editor is exactly what gets exported — verified frame-for-frame against the preview.
Measured on real devices, on real 4K footage — not a synthetic benchmark.
real caption templates — every rendering mechanic — rendered at full quality and visually verified on real 4K device video.
to burn a full, animated, per-word-timed caption track onto a clip — fast enough to feel instant, measured across 30 of 38 styles.
to reframe a long video into a captioned vertical highlight clip with automatic face tracking, ready to post.

BurnKit and ClipKit weren't built by studying video editing in the abstract. They came out of more than two years spent studying how creators actually shoot, edit, and post — running our own content brands day to day, hitting the same laggy-preview, "just wait for the render" friction every creator on a phone deals with. That's the problem we set out to solve structurally, not paper over with a faster loading spinner.
Every engineering decision underneath BurnKit and ClipKit — including how the two share a common foundation instead of drifting apart as two separate technologies — was made deliberately, the same discipline you'd expect from infrastructure meant to be licensed and relied on, not a one-off feature.
BurnKit is Cinematic Pro's proprietary real-time engine for burning captions onto video. It renders animated, per-word-timed captions directly onto a clip at full quality, in seconds, matching the in-app preview exactly.
BurnKit burns a full animated caption track onto a clip in about 2–3 seconds, measured across 30 of 38 real caption styles on real devices — fast enough to feel instant instead of a wait.
ClipKit turns a long landscape video into a vertical highlight clip — cropping and panning with automatic face tracking to keep the speaker in frame, then trimming and exporting a ready-to-post clip in about 16 seconds.
