Yes, it's called adjusting the bitrate.....but you will never keep the VOB file size close to the original 300MB that is inside the MKV.

don't think thats in convertxtodvd, looked high and low in settings and so on, didn;t see it....

whats the lowest rom you can get the vob to be anyways with any app you think?

Under settings and encoding can you change the target size. You can try set it to 300MB... But too low size/bitrate=crappy video quality.

Depends on your source and your perception of "Quality" - but for what's worth: DVDStyler issues a warning when the bitrate goes below 2 Mb/s.

Why do you keep asking about "VOB" files?
A vob file is ONLY useful inside the DVD environment. A single 1.8gb "vob" file is not even valid for a real DVD. If you are trying to convert and burn the contents of this MKV file to a DVD(playable on a DVD player), 1.8gb is completely WRONG. VOB files within a genuine DVD must be under 1gb in size. There may be several VOB files on a DVD but all of them must be under 1gb each.

If you are treating a "vob" file as if it were something like a "avi" or "mp4" file....you and the person telling you this is dead wrong.

hech54 is right. Can't figure how this thread went off kilter for so long in the first place. Myself, I haven't used convertxtodvd in a coon's age, but I'd never figure out how to get a 1.8GB "VOB" out of it.

Something you should know: "mkv" isn't a format, it's a container. An mkv can accept video using several different codecs. VOB for DVD is encoded as MPEG2. So we don't know what kind of mkv you're talking about, how it's encoded, or what you're trying to do with it. I'd guess you're trying to make an mkv into a DVD. But that's a guess.

In case you haven't seen it, these are the encoding specs for PAL/NTSC DVD: https://www.videohelp.com/dvd#tech
And the files in a DVD disc look like this: https://www.videohelp.com/dvd#struct
You don't have to take hech54's or my word for this if you don't want to, but you can trust the specs -- a VOB video file on an authored DVD disc can't be more than 1.0GB in size. That means 1,024MB in anyone's book.

oh i played around with the target size, 500 mb not too bad, dunno if i actually use that for dvd.

pardon if there were confusion for vob term. i meant the whole dvd output. well it did turn out to 1.8 gb from 300 mb. think the encoding setting was on 4.7 gb disc. thats just what i got. dunno what to say if people surprised with that. *shrug*

If you're happy with it, OK. Still doesn't answer the questions, though. The results are 600% bigger than the original 300mb video. That would indicate a low-bitrate original (? maybe) re-encoded to a much higher-bitrate output. The mkv is the big unknown. We don't know the original mkv bitrate, frame size, audio sampling rate, duration, encoder, etc., etc., so not much can be determined.
