VOB الأسئلة الشائعة حول التحويل
What is a VOB video file?
+
VOB is a video container that holds one or more video streams, audio tracks, and optional subtitles. Different containers support different codecs, so compatibility depends on both the wrapper AND what is inside it.
Why convert VOB to another video format?
+
Convert VOB to MP4 when you need universal playback — web browsers, mobile devices, smart TVs and editing apps all play MP4 natively. Convert to WebM for web embedding where smaller file size matters. Convert to MOV when working in Final Cut or other Apple-native pipelines.
Does VOB conversion re-encode the video?
+
When the source codec inside VOB is compatible with the target container we remux without re-encoding (fast, lossless). When the codec must change (for example HEVC to H.264) the video is re-encoded — slower, with a small generational quality cost.
How long does converting a VOB file take?
+
For short clips (under a minute), VOB conversion typically finishes in seconds. For multi-gigabyte recordings, conversion runs at roughly real-time or faster on our GPU encoders, so a 30-minute clip lands in 5-15 minutes.
Will my iPhone play a converted VOB file?
+
iPhones play MP4 with H.264 or HEVC natively. If your destination is iPhone, convert VOB to MP4 — the result drops straight into Photos via AirDrop or iCloud.
Can I compress a VOB file to email it?
+
Yes. Use MOV.to's compress tool to drop bitrate and resolution. A 1080p clip shrunk to 720p at 2 Mbps usually fits the typical 25 MB email attachment limit while still looking sharp for the recipient.
Are subtitles preserved when converting VOB?
+
Yes — embedded subtitle tracks in VOB are carried through to formats that support them (MP4, MKV, MOV). MOV.to also lets you generate fresh AI subtitles from the audio track during conversion.
Does the VOB converter on MOV.to require an account?
+
No. Drag a VOB file in, pick a target format, and download — no signup. An optional account unlocks larger files, batch jobs, and conversion history.
What is the largest VOB file MOV.to will accept?
+
Free users go up to 100 MB per file. Pro plans extend that to multiple GB so you can convert full-length VOB recordings and 4K source footage.
How do I rotate or trim a VOB before converting?
+
Use the VOB editor tools — rotate, trim, merge, speed-adjust and resize all run in the browser before you commit to the conversion. The result keeps your edits and lands in whatever target format you picked. MP4 with H.264 video is the safest target for sharing — every browser, every phone, every editor opens it.
