Upload the MP4 file and our converter applies a CRF-based re-encode targeting visually-lossless WebM output (CRF 18 by default, lower = larger / higher quality). The codec is chosen to match the WebM container — H.264 / H.265 / VP9 / AV1 as appropriate.

Yes — audio is re-muxed when MP4 and WebM share an audio codec, or re-encoded to AAC / Opus / Vorbis depending on what the WebM container supports. Multi-track audio (commentary, alternate languages) is preserved in containers that support it (MKV, WebM, MP4).

Depends on the codec change. Same-codec re-mux: 30-60 seconds (no re-encode). Re-encode to a different codec: typically 0.3-0.7x source duration on our GPU pipeline, so a 1-hour MP4 -> WebM finishes in 18-40 minutes; AV1 re-encodes are 2-3x slower.

Almost always a bitrate-too-low setting. Re-encoding a high-bitrate MP4 into a lower-bitrate WebM at the default CRF compresses motion-heavy scenes heavily. Push CRF down to 16-18 (or set an explicit bitrate ceiling) and re-run to recover quality.

Yes — embedded subtitle tracks (mov_text in MP4, SRT / ASS in MKV, WebVTT in WebM) are preserved when both MP4 and WebM containers support them. Burned-in (hardsub) subtitles transfer automatically because they are part of the pixel data.
