How do I re-encode M4V to MP4 without quality loss?

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

Which codec does the MP4 output use?

Same-codec re-muxes (e.g. M4V → MP4 where both use H.264) produce nearly-identical sizes. Codec changes can swing the size dramatically: H.264 → H.265 typically halves the file at the same visual quality; H.264 → VP9 is roughly comparable.

Up to 8K (7680×4320) on Premium. Free users are capped at 4K (3840×2160) per the file-size limit. HDR metadata (HDR10, Dolby Vision) is preserved where both M4V and MP4 containers support it.

Can I crop or trim during the M4V to MP4 conversion?

Not in the same step — use /video-trim/ or /video-cutter/ to trim before converting, then queue the M4V → MP4 step. Trimming and converting in series is faster than re-encoding the whole file just to crop.

Yes — embedded subtitle tracks (mov_text in MP4, SRT/ASS in MKV) are preserved when both M4V and MP4 containers support them. Burned-in (hardsub) subtitles transfer automatically because they are part of the video frame.
