How to use Subtitle Burner

Hardsubs vs Softsubs

Burn-in bakes captions into pixels—compatible everywhere, permanent, and hard to fix typos later. Soft SRT/VTT tracks stay editable. Prefer burn-in when platforms strip external tracks or re-encode aggressively.

Deliver a widely playable file via the MP4 Converter or WEBM Converter before burn-in. Grab a thumbnail from the same timeline with the Video Frame Extractor.

Timing & Encoding

Offsets of 200–400 ms are common after re-encodes. Spot-check dialogue early and late in the timeline. Unicode and CJK fonts must exist on the renderer or characters drop out as boxes.

How Subtitle Burner differs from typical alternatives

Compared with Subtitle burn-in tools such as Kapwing: Kapwing stores video projects in cloud workspaces and expects account login for HD exports and collaboration. Big File Sharing focuses on free one-off jobs, no mandatory signup, and short-lived temporary files instead of account-centric project history.
