Hi all;

I'm converting a MKV file to an AVI file, and so far everything seems to be ok. The only thing however is when I rip the subtitles from the MKV file into an STR file, I can't for the life of me splice it back in, when I'm reencoding it into an AVI file. Could someone please help me out here?

Thanks in advance

AFAIK, AVI can only hold a very limited set of subtitles, if at all.
So you have to either burn them in, or leave it as MKV. (Or chose another format that supports subtitles.)

Matroska/MKV ?

Well, thereŽs the Subtitle filter for VirtualDub, but it only accepts SSA subtitles. Perhaps youŽll find a converter somewhere.

But since that will recompression of the video, IŽd suggest you try to find out if there is a subtitle format accepted by AVI. As I said, IŽm not sure - hopefully someone with more knowledge will jump in and tell.

Is the conversion to AVI really necessary?

in principle all textbased subs should be possible in AVI

AVIMUx GUI can currently mux srt and ssa in AVI. But i have the same question as Cyberman: why do you wanna do so?

Guys, you confuse the poor guy even more smile.gif

Virtualdub can not combine SRT subtitles as a separate stream with the video and audio together into an AVI file. So, if you insist on using AVI, here are your choices :

1. Use Alexnoe's avi-mux GUI to combine your AVI file ( with audio and video ) and your SRT file ( the subs, as a separate text stream ) into a single AVI file. However, most tools to handle AVIs cant handle this separate subs track in the AVI, and will either b0rk on this file if you try to edit it afterwards, or ignore the subs. However, the file should play fine on Windows Mediaplayer, if DVobSub ( vsfilter ) is installed.

2. Recompress the AVI and 'hardcode' the subtitles into the video stream, so they become a fixed part of the picture. This sucks, because the quality will degrade a lot, it will take hours of recompression and there is no proper way to remove the subtitles anymore after that, unless you want to use a filter for that and take into account that the quality gets even worse !

My tip :

Leave the matroska source file as it is, and teach your friends how to play MKV files wink.gif ... its going to replace AVI anyhow, sooner or later .....
