Welcome to TVPaint Community forums !

Hello,

My MP4 export was not working, so I uninstalled my 11.5.3 version off of my computer and re-downloaded and installed it. Im getting an error code: tvpaint avcodec_open2 -1313558101.

Not sure what it means or what I'm doing wrong! Im on a 64x Windows 11 computer.

Hello, I think resetting your TVPaint's configuration might help.

First, you can export your custom settings: https://www.tvpaint.com/doc/tvp11/index ... m-settings

Keep CTRL pressed when launching TVPaint via the desktop shortcut. The Startup Panel should appear. From there, you can create a new config file from scratch, copy or delete one.

What you need to do is delete you current config and create a fresh one, indeed. Then launch TVPaint as usual.


If it doesn't work, press Windows + R and write %appdata% in the field, then press Enter.

You will be taken to a hidden system repertory, look for the TVPaint folder, then inside the "default" folder, delete the config.ini file.

This will reset your TVPaint's configuration.
