MKV 8bit to 10bit subtitle help!

[lolek31]

So i've been trying to re-encode a mkv that is 8bit to 10bit with subs, but for some reason as the anime progresses the video runs faster then the original making the subs all out of sync. The frame rate are both the same.

Below are picture of both video streams at exactly the same time:

Re-encoding from 8 bit to 10 bit will gain no quality. If anything you will loose quality.

10 bit has a better quality over file size ratio, i'm not trying to improve quality by encoding from 8 bit to 10 bit im trying to lower the file size from 450mb to 100 mb and have the best quality for size.

You are just going to ruin it man. You already have a perfectly good file and you want to reduce it by more than 1/4 the size? Stop having such insane thoughts.

Hahaha trust me i have the same thought, but im trying to host low size anime, for people with limited bandwidth. I prefer my anime 1080p and 1gb+ per ep in size

Listen what FulciLives says. Quality will be noticable worsen . Even 10bit won't help.

I know, but for the original question, does anyone know why the videos would switch speeds while having the same frame rate?

[FulciLives]

Perhaps the original was encoded with a variable framerate instead of a constant framerate. If true you can pretty much format about ever converting it and getting it to work. I've run into such files before and they are worthless.

I finally managed to do it check it out 102mb file and the quality might be a lot worse but still its not too bad for the size -> www.etsu.me

It was the program I was using, it was screwed. So I just used the command line as it was much easier. For people with the same problem in the presets insert: --fps (fps output you want it to be). The program didn't do it
