Upload your VOB file and set Quality to High Quality in the conversion options. That re-encodes the video at the highest quality setting (CRF 18 for H.264 and VP9 output), which keeps the most detail at the cost of a larger file. The default, Balanced, uses the standard setting. The MPG output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. VOB na da MPEG-2 bidiyo, AC-3 ko PCM sauti, da DVD subpicture subtitle streams, raba zuwa 1 GB segments by the DVD spec.

It depends on the MPG container. MP4, MOV and MKV output use H.264, which plays on practically every phone, browser and TV. WebM output uses VP9. AVI, WMV and MPEG output use the older codecs those formats were designed for.
Shin waƙoƙina na sauti za su iya tsira daga canji daga VOB zuwa MPG?
+
Yes, the main audio track comes through, re-encoded to a codec the MPG container plays, for example AAC in MP4 and MOV or Opus in WebM. Most conversions keep only that one track (the one with the most channels), so alternate languages and commentary are dropped. MP4 to MOV, and AVI, WMV, MPEG, FLV, VOB or M4V to MKV, keep every audio track.

There is no fixed time: it depends on the length, the resolution and the target format. Conversions run on our servers' CPUs with software encoders; there is no GPU acceleration. MKV to MP4 or MOV with the default settings copies the video stream and is the quickest. A re-encode to H.264 takes longer, and WebM (VP9) is the slowest target, several times slower than H.264 in our tests.
