MKVToolNix GUI - How to "Force Display" a subtitle on many .mkv-files

[vhwul62]

Right now I need to open each .mkv, then select subtitle, set "Forced display" flag > Yes.
That works fine.

Is there a way to do this for a number of .mkv's, so I do not need to open them one by one?
So, I have, let's say a dozen of .mkv's in the same folder.

Thanks!

Make a batch file using mkvmerge with the --forced-display-flag option.

For good order's sake, they shouldn't be merged into 1 single file.

Is jMkvpropedit of any use?

Thanks. Frankly, I was hoping for an 'easy' way for non-experts. Some sort of settings within MKVToolnix.
Anyway, right now I went on to process each file separately.
So, start mkvtoolnixgui, add source file, select language set forced display = Yes - start multiplexing, exit, start mkvtoolnixgui.exe and so on.
Thanks again.

Well you don't give enough info.

But assuming each file has 3 tracks: A video, a audio and a subtitle track a batch job could look like:

if not exist forced md forced
for %%g in (*.mkv) do (
mkvmerge -o "forced\%%g" --forced-display-flag 2:yes "%%g" --track-order 0:0,1:0,2:0
)

Thank you. I wish I could add all files from an entire folder, then set the Forced Display flat then run.
Regretfully Mkvtoolnix creates 1 big file, instead of all separate files. Haven't found a way to have MKVToolnix create separate files, named after the source file.
(i.e. similar to when I create a job 1-by-1)

Perhaps try on output tab to "Split before chapters" together with "One chapter for each appended file"

Maybe I'm missing something, but I don't think any remuxing is necessary. OP's goal requires no more than setting a header boolean.
Drag & drop your mkv onto MKVToolNix's Header editor. Expand the target subtitle track. In the list, select "Forced display" flag. In the settings window on the right, check "Add element" and set value to "Yes". Type Ctrl+S to save. Done. No remuxing needed.

Maybe my small batch file called ForceSubs.cmd


Save the following as ForceSubs.cmd and run it from the folder containing your MKV files.
Output in the New\ folder.


Your path to mkvmerge.exe may be different.

if not exist New\ md New
for %%a in (*.mkv) do (
"C:\Program Files\MKVToolNix\mkvmerge.exe" --output "New\%%a" --forced-display-flag 0:no --forced-display-flag 1:no --compression 1:none --sub-charset 2:UTF-8 --language 2:en --forced-display-flag 2:yes "%%a" --track-order 0:0,0:1,0:2
)
