We have tested it already on our projects for two years already and it have following improvements:
– Basic CLI support. Allows to automatically integrate with other software like Remake
– Export to video file. Audio layers are mixed with video. To select video format use an ‘appropriate’ filename extension (ex: .avi, .mov, .mpg, .mp4…), movie framerate is selectable (but output codecs don’t support all framerates, a safe and usual choice should be 24, 25 or 30 fps).
– Audio playback fixed.
– Fixed saving animation (removed ‘optimization’, now saving is slower but safer)
– FPS parameter is saved in the project file now.
– 3 ‘layers’ of onion skinning. Configurable trough edit->preferences->tools, to remove a layer set its opacity to 0.
– Import movie function. Frames are imported at the current fps, there is no check to limit the imported frames.
– Duplicate keyframe function.
– Fix artifacts happening when moving bitmap layer.
– Keybindings to control the applications
– Fix transperency bug when export to png sequence
Some of those fixes are patches found on the old Pencil forum, some of them our own enhancements.
