MOV to VOB Conversion FAQ
How do I re-encode MOV to VOB without losing video quality?
+
Upload your MOV file and the converter runs a CRF-based re-encode targeting visually-lossless VOB output (CRF 18 by default, lower values = larger file / higher quality). The codec is chosen to match the VOB container — H.264 for broad-compat MP4, H.265 for size-efficient MKV, VP9 for WebM, AV1 for newer pipelines. A MOV normally carries H.264 or HEVC for delivery, or ProRes when it is an editing master, alongside AAC or uncompressed PCM audio. A VOB holds MPEG-2 video, AC-3 or PCM audio, and DVD subpicture subtitle streams, split into 1 GB segments by the DVD spec.
Why would I convert MOV to an older format like VOB?
+
Because a lot of hardware never learned anything newer and never will. DVD players, in-car head units, camcorder playback modes, industrial displays and plenty of broadcast ingest equipment accept VOB and nothing else. The conversion is a deliberate step down in efficiency, bought in exchange for working on a device that has no other option. VOB preserves the whole DVD payload — multiple angles, multiple audio languages and subtitle tracks all survive inside it.
Which video codec does the VOB output use?
+
It depends on the VOB container. MP4 defaults to H.264 for the broadest playback support across phones, browsers, and Smart TVs. MKV defaults to H.265 / HEVC for roughly half the file size at equivalent quality. WebM defaults to VP9. The advanced options expose explicit codec choice if you need to override. VOB is the Video Object container found in the VIDEO_TS folder of every DVD — an MPEG-2 program stream with DVD-specific navigation data added.
Will my audio track survive MOV to VOB conversion?
+
Yes. When MOV and VOB share an audio codec (e.g. both carry AAC), audio is re-muxed with no re-encode — bit-identical. When the codecs differ, audio is transcoded to AAC / Opus / Vorbis depending on what the VOB container supports. Multi-track audio (commentary, alternate languages) is preserved.
Can I keep the original framerate when converting MOV to VOB?
+
By default yes — a 24fps MOV stays 24fps in VOB; a 60fps MOV stays 60fps. If you need to change rate (e.g. interlaced 29.97 → progressive 30, or 60 → 30 for upload limits), the framerate option handles 3:2 pulldown, deinterlacing, and frame-blending in the same encode pass.
How much will the file size change going from MOV to VOB?
+
Same-codec re-mux (MOV H.264 → VOB H.264 just changing container): nearly identical size. Codec change can swing dramatically: H.264 → H.265 typically halves the file at the same visual quality; VP9 is roughly comparable; AV1 cuts another 20-30% but is slower to encode.
Will the VOB file play on iPhone, Android, and Smart TVs?
+
MP4 / H.264 plays natively on every modern device. MOV / H.264 plays on Apple devices and most TVs but not always on older Android. MKV needs VLC on iOS. WebM is browser-first. The advanced options include a "device compatibility" preset that picks the safest VOB codec / container for your target. VOB is split across files, may be CSS-encrypted, and carries navigation packets that confuse general-purpose players.
How long does converting a 1-hour MOV video to VOB take?
+
Same-codec re-mux is near-instant — 30 to 60 seconds for a 1-hour file. A full codec re-encode runs at roughly 0.3-0.7x source duration on our GPU pipeline, so a 1-hour MOV → VOB finishes in 18-40 minutes depending on resolution and target codec.
What is the maximum resolution supported for MOV to VOB?
+
Up to 8K (7680×4320) on Premium plans. Free conversions are capped at 4K (3840×2160) by the per-file size limit. HDR metadata (HDR10, HDR10+, Dolby Vision when present) is carried through where both MOV and VOB containers support it.
Is my MOV video private during conversion to VOB?
+
Yes. Uploaded video files are processed in isolated workers, never viewed by a human, never indexed, and deleted within minutes of completion. The retention window is documented at /privacy/ and we publish no training corpus from user uploads.
Can I crop, trim, or rotate during the MOV to VOB conversion?
+
Not in the same step — use /video-trim/ or /video-cutter/ to clip first, then run the MOV → VOB conversion. Chaining trim and convert is faster than re-encoding the entire MOV just to drop unused footage.
Why is the VOB file blurry compared to the MOV source?
+
Almost always a bitrate-too-low setting. Re-encoding from a high-bitrate MOV into a default-CRF VOB compresses heavily on motion-rich scenes. Push CRF down to 16-18, or set an explicit target bitrate matched to the MOV source, and the VOB regains its clarity. MOV is the format professional editors ask for, because it survives repeated round-trips through Final Cut Pro, Premiere and DaVinci Resolve without generational loss.
