Subtitle display

[Acetyl]

In an attempt to preserve the lossless quality of some source files, I've opted to mux the elementary streams into an MKV container and use the "crop" function to remove the black borders along the sides. Unfortunately this doesn't reduce the file size, though I already assumed that was the case, but it also seems to be rendering subtitles with a very squished appearance. Some players just outright ignore the cropping, though that's comparatively rare.

Is there any sort of obvious solution I'm overlooking? It's not really a major problem, but I'd like to try to fix it.

Appreciation in advance.

What kind of subtitles? text based srt/ssa/ass or image based sub/idx/?
Do you have to crop? Use the player to zoom instead?
What do you play with?

The crop function in mkvtoolnix just adds a header tag and it will not reduce any file size. THe only way to reduce file size is to reconvert with a lower bitrate.


And I'm moving you to our subtitle section.

I do, even if it's only soft cropping. Reducing file size would only be a bonus, despite probably saving 30 gigs at the very least.
The actual visual part of the video is 1520x1078, (1920x1080 source) without cropping it doesn't fill the entire upper and lower parts of a monitor. I guess you could say it gives it a letterboxed look on a 16:10. Although zooming might work, I'd rather the attribute be inherent to the file.

I'm working with text based .ass, softsubs. Maybe their positioning is faulty now that the player assumes a different stream resolution than it really is?

Aye, I suppose I expected as much. I had just never taken direct notice of it before, so it was interesting. Unfortunately I don't have any encoder that would preserve the original quality. Even if I remove the audio tracks first, and just edit the .h264 stream itself, it still doesn't come out quite right.

Okay. I wasn't sure where to post.
