Watermark to a .mkv file

[fatammag]

Can someone explain me how to add a watermark to a mkv video file without re-encode?
Thank you!

You can't.

Without re-encoding it can only be a removable subtitle file.

OK. Can I do this while i encode a DVD movie to .mkv format?
I am using Handbrake 0.9.9 for the encoding.

Yes, but the question is: do you re-encode your DVD to h264 or you only mux it to mkv?

If you use the first option you can watermark the video using i.e. hard coded subtitles. I don't remember if Handbrake has option to add a picture as watermark to output video.

If you only mux (change the container from vob to mkv, without re-encoding), then you also can add subtitles. However, in that case they can be removed or replaced by remuxing the mkv file.

I am using Handbrake to make a DVDRip. Like the scene groups. Handbrake can't hard code subtitles :/
