chapters in a mkv

[aldaco12]

Hi. I recently had to re-build a MKV file because my HD player didn't read subtitles in SUB+IDX format.
Therefore I extracted the subtitles, I ripped them in a more suitable form (ASS, SRT or so) using Vobsub than I made a brand new MKV using the video and audio channels extracted from the original movie and the new subtitles I created.

What I wasn't able to do is to re-import the chapters. MKVExtrat GUI extracts the chaptes in a .xml format, and I haven't seen, in MKV Merge how to import such chapters file. What have I to do?
Thanks

In mkvmergegui under the top menu(not the tab) Chapter Editor->Load and import the xml.

And mkv is not blu-ray authoring. Moving you to our video conversion section....close enough.

I'm not sure you need to use MKVMergeGUI's chapter editor. You can add existing chapters to MKVs under the Global tab and the chapters section near the bottom. It'll load xml chapter files.

Keep in mind you don't actually need to extract streams in order to mux them into a new MKV. For example you could open your original MKV with MKVMergeGUI, add the newly created subtitles, deselect the original subtitles if you want to, re-order the tracks if you like, then save that as a new MKV. If there were chapters in the original MKV, they'll be carried over to the new one along with the original video and audio etc, as long as you don't de-select them in the tracks list.
Doing it that way is often a good idea as it allows MKVMergeGUI to keep the sync between tracks the same, so you don't need to worry about that sort of thing yourself. For example if the audio stream had a delay relative to the video in the original MKV, it'll have the same delay in the new one.

You can do the same with other file types as the input. AVI, MP4, etc.

Slightly off topic - a good source of chapter xml files is here

mkvextract chapters source-filename > chapter-filename
mkvpropedit target-filename --chapters chapter-filename
