BD-RB:Subtitle question

[Hobojobo]

I am using BD-RB's alternate movie-only output to make mkv out of my blu-rays.
I use the alternate output profile MKV, 1080p, intact audio.

BD-RB processes the subtitle streams to i.g. 0000.track_4608-rz.sup, which is bigger in size than the original 00000.track_4608.sup.

Why does BD-RB do that and what are the differences of these subtitles

THX.

THX.That's a resizing of the subtitle. What size is the original? If there is no need to resize it should stay exactly the same. If it is going to 1080p from a smaller size (say 720p) than it would naturally be larger.

That's what I thought.
But, as I said, I am using MKV, 1080p, intact audio profile.
There should be no resizing, shouldn't it?
And the file size of the resized subs is bigger than the original. :scared:

I just ran a transcode of Harry Potter III.
I will post the results, when the job is finished.

I'll take a look at it for the next release. Maybe it is getting resized even when it isn't necessary.
