Window resolution could be set in the Display settings menu to the maximum resolution supported by hardware (ie it makes possible to take screenshots larger than screen)
Restored old video capture mode as a set of screenshots
Video files (avi) or screenshots are saved to the screenshots/capture/ folder
Menu for video capture settings: switch between set of screenshots mode and avi mode, choosing screenshots format and codec settings
The F9 key brings up the Video capture menu, Ctrl-F9 starts and stops the video recording with the choosen setting
The engine automatically searches the lower free number for the file name by scanning the folder screenshots/capture/. I.e. if the folder have the files vid00000.avi and vid00001.avi, the next recorded video file will be vid00002.avi. Just like saving of the regular screenshots.
Should I make a similar screenshots settings menu? It will have only image format selector and a checkbox for the GUI.
