What tool(s) for MP4 to MKV conversion with no reencoding?

Put "pause" on the next line. That will keep the window open until you press a key.

On which line? There's no script that I'm running. You either run it from the command line or drag a .mp4 onto it's shortcut icon. In either case there's no way to keep the resultant popup cmd window open long enough. Once you get back to DOS prompt, the window has already gone. The pause will have to be put by the author in the program source code.

Use a batch file. Something like:

"G:\Program Files\mkvtoolnix\mkvmerge.exe" --output %1.mkv %1
pause

Change the path to mkvmerge.exe. And you may need to add more options to the mkvmerge line.

I don't think I was clear. I'm using mp42mkvac3, not mkvmerge. What you said would work if I'm calling mkvmerge manually, which I'm not. It's called from mp42mkvac3.exe internally.

The thread mentions several programs. How am I supposed to know what you're using? In any case, using a batch file with "pause" will leave the window open until you press a key.

Sorry thought I was clear. But no, a pause within the batch file doesn't since mp42mkvac3 is opening a secondary cmd window to run in. That's the one that closes so fast that you cannot see what it says. There's no way to stop that window from closing, AFAICS.

Ah, I see. I thought it was the window that was running mp42mvkac3 that was closing too fast.
