MKV Hardcode Subs

[Mohamet]

Hello! What is the best way to burn / hardcode subtitles to a .mkv file ?

Thanks

[videobruger]

I would use FFmpeg.

[Mohamet]

I would use FFmpeg.

Yes, but how ? What strings you use ?

Thanks.

[videobruger]

In the simplest form it would be (provided FFmpeg is installed in your PATH) and the format of your subtitles is .srt

FFmpeg -i in.mkv -vf subtitles=subs.srt HCout.mkv

[ProWo]

You can also use clever Ffmpeg-GUI

[videobruger]

Or you could use Subtitle Edit.

Drop your subtitle on it. If the video has the same name it loads automatically. Else use "Video -> Open video file"

Then use "Video -> Generate video with burned-in subs" and you can give some settings.

As far as I remember SE will download FFmpeg if it's not installed

VidCoder.

I downloaded but i dont see how can i do it! Any help please?

Great idea! I make it and work fine but the problem is for example if my video are 1.40GB the new video file is 900MB! How can i get the same size ?

VidCoder.

VidCoder re-endocde the video so its not good for me!

[davexnet]

You have to re-encode if want the subtitles burned in

Do you actually need them to be burned in or how about switchable and making the subtitles both "the default and forced" assuming your media player recognises those flags? If you really need to burn in the subs into the video then that always involves re-encoding the video with some loss of quality.

By ticking the "File size"checkbox and use 2-pass encoding,

As already said hardcoding requires re-encoding.

I try it, but again have less size and not the same! From 1.44GB i get 900MB.

Yes, i need thems hardcoded and not as a second part to my video file

[ProWo]

Load your file, wait until analysis is done, click main, click convert Videostream, click keep size and voilà, you are there.

I do it but the size again are smaller! I get 700MB from 1.44GB!

[ProWo]

Use crf 18

[Mohamet]

Use crf 18

Where ?

[davexnet]

Use crf 18

Where ?

Right here

[Mohamet]

Use crf 18

Where ?

Right here

I do it but again get 800MB! I dont wanna change my size!

I need something like the AVIRecomp but for MKV files!

I don't know Prowo's software that well, but to achieve video of a certain size, you need to do a 2-pass encode.
I have not see anywhere in Clever ffmpeg GUI that 2-pass is implemented.

Try Vidcoder. On the video encoding tab select target size, 2-pass and select "burn in" for the subtitle (main screen)

[blud7]

You can also use Handbrake. But Vidcoder is a good alternative.

[ProWo]

I have not see anywhere in Clever ffmpeg GUI that 2-pass is implemented.

2 pass encoding is not implemented because the contant rate factor (CRF) encoding provides the best quality and an exact file size is uninteresting for most users.

[videobruger]

I try it, but again have less size and not the same! From 1.44GB i get 900MB.

I don't know your settings.

But using this:

The result is:

The subtitles are .srt and embedded in the file Video.mkv.

That's cool; I'm not judging it, but the person I was trying to help specifically asked for a file of a certain size ...

Awesome! Work perfect with this way!

Big thank to everyone to to try help me

[Mohamet]

Hello again guys! This time, i wanna hardcode subtitles to a mkv but get again a mkv file without add or less the size (not much at least).

[jagabo]

If you want the same size use the same bitrate. But the same size doesn't mean you'll get the same quality.

Thank you but you dont provide me any suggestion about the application ?

[ProWo]

Learn by yourself.
Read:
https://trac.ffmpeg.org/wiki/Encode/H.264
(two pass section).

It doesn't matter what application is used. The definition of bitrate is:

bitrate = stream size / running time

hence, via simple algebraic manipulation:

stream size = bitrate * running time

So, no matter what application you use, what codec you use, or the properties of the video, the bitrate determines the size.
