Add option to adjust playback speed

Hello, thanks for the good program you have created
Please create an option or shortcut key to reduce or increase the speed of video playback or read text to the program for files that we add to the program
Thank you

Hello @TAK_YEK !
We already have this feature in the VideoFiles section. You can change the playback speed to 0.8 - this works for the whole Media section. :slightly_smiling_face:
