Soft subtitles (selectable tracks) survive when M4V can carry them: MKV holds SRT, ASS, SSA, PGS, VobSub natively; MP4 only holds mov_text (a stripped-down format). Converting an MKV with ASS styled subs to MP4 will typically downgrade them to mov_text or burn them in. Hardsubs (burned into the video) carry over regardless.
Does MPEG to M4V keep chapter markers / DVD-style navigation?
+
Chapter metadata transfers between MPEG and M4V whenever both containers support a chapter atom (MKV, MP4, MOV). WebM stores chapters in a Matroska-compatible block, so MKV <-> WebM chapters round-trip cleanly. AVI has no chapter spec, so converting AVI to M4V produces an unchaptered file unless you add markers manually.

MKV is the only mainstream container that stores arbitrary attached files (TTF fonts for ASS subs, JPG cover art, fan-translated PDF inserts). Going from MPEG to M4V drops these attachments when M4V is not MKV — the elementary streams convert, but the attached payload stays in the source. Keep MPEG as a backup if you depend on attached fonts.
Which codec does the M4V output use by default?
+
The default codec is chosen to match the M4V container conservatively: MKV defaults to H.265 (HEVC) for better compression; MP4 defaults to H.264 for the widest device support; WebM defaults to VP9; AVI uses MPEG-4 ASP (DivX/Xvid lineage). Override via the advanced codec dropdown — AV1 is available for MKV / WebM where you want maximum compression and can wait through the encode.

Same-codec remux produces a near-identical size (container overhead differs by 0.1-2%). A codec change can swing the size by 50% or more: H.264 to H.265 typically halves the file at the same visual quality; H.264 to AV1 halves it again on a slow preset. Going from a high-bitrate MPEG (Blu-ray rip) to a low-bitrate M4V (web upload) is the most common reason for a dramatic drop.

Yes — uploaded MPEG files are processed in isolated workers and deleted within minutes of completion. We never view, store, retain, or share the content. See /privacy/ for the data retention window. The conversion pipeline runs on hardware we control end-to-end; no third-party APIs receive your file.

Not in the same job — keep conversion focused on container / codec. Use /trim/ to clip the MPEG first, then queue the MPEG -> M4V step. For joining several clips into one M4V, the /merge/ tool stitches them on a per-codec basis (it remuxes when the inputs share a codec, re-encodes otherwise) and emits a single M4V file at the end.
