Avidemux Forum

The "Save Current Settings as Default" menu option no longer seems to be honoured for Video settings. In the next session Video resets to Copy, and the Config reverts to default values.

I am running Avidemux 2.8.2 260516_46963d075c1-fflibs 7.0.2  mingw 64bit
under Windows 11 on an Intel PC, with a local account.

I also have an old version that works fine in this regard,
on a Windows 10 AMD PC, with a Microsoft account.
Avidemux 2.8.2 250526_b008a4d098-fflibs 7.0.2-VC++

At least the current git master works fine (on Linux, testing on Windows is not possible for me ATM) in this regard. From 2026-04-08 to and including 2026-05-29 is a very unfortunate time range as opening MPEG-TS streams with MPEG-2 video was broken.

If you don't need MPEG-2, it should be more or less fine function-wise. Can it be that you access the same Avidemux profile from different Avidemux versions? As configuration was changed on April 8, returning to an earlier build may be problematic. In doubt, please rename %appdata%\avidemux directory and retry with 260516.
