Upload the MP4 file and our converter applies a CRF-based re-encode targeting visually-lossless M4V output (CRF 18 by default, lower = larger / higher quality). The codec is chosen to match the M4V container — H.264 / H.265 / VP9 / AV1 as appropriate.
Which codec does the M4V output use?

Yes — audio is re-muxed when MP4 and M4V share an audio codec, or re-encoded to AAC / Opus / Vorbis depending on what the M4V container supports. Multi-track audio (commentary, alternate languages) is preserved in containers that support it (MKV, WebM, MP4).

Up to 8K (7680x4320) on Pro. Free is capped at 4K per the file-size limit. HDR metadata (HDR10, Dolby Vision) is preserved where both MP4 and M4V containers and codecs support it; SDR sources stay SDR.

Almost always a bitrate-too-low setting. Re-encoding a high-bitrate MP4 into a lower-bitrate M4V 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.
Does the MP4 to M4V converter support subtitles?
+
Yes — embedded subtitle tracks (mov_text in MP4, SRT / ASS in MKV, WebVTT in WebM) are preserved when both MP4 and M4V containers support them. Burned-in (hardsub) subtitles transfer automatically because they are part of the pixel data.
