Adjust brightness and clarity for several videos simultaneously.
I don’t understand why it matters, but both are fine. You only need to modify the files directly, without affecting your monitor settings.
You might want VirtualDub, it handles re-encoding all files but batch processing is possible. I haven't used it recently, so don't inquire about that. You'll need the x264vfw codec and the specific codec your files use—likely x264 as well. It supports AVI files only; if your files are MP4 or MKV, you'll have to convert them first to AVI.
WinFF, a graphical interface for FFMpeg, handles this conversion. It transforms any video format into another seamlessly, offering choices between direct conversion (no encoding) or transcode.
