Like GIMP or Blender? Both pretty complicated.... and very useful. They're open source as well! I'm starting some courses on them. You know how you need a custom pic I'm trying to get that done myself now too cause than you know EXACTLY how it will look.
Irfan by Irfanview I've used for years and free with good help and annual updates too used GIMP but by far Irfan is easier IrfanView 64-bit version IrfanView - Wikipedia ps best is the free plugins
Once you know it, depends on how much your creating and rendering vs compiling. It's just such amazingly able program, the real task is not focusing on any other feature than using the video editor. If your not making your assets and your just importing media(photos and music) than fairly quickly. So If you already have your clip and you just want to loop it and compile it not long. Really depends on what your looking to create. However if you want to start making effect titles and using some of the cool features it does have to offer- it can take a very long time. I love Blender! Like I took forever making a lamp on a desk and animating it to jump and grow legs- was thirty seconds but doing it took way too long.. tons of fun though. God I need to get outta the weeds and back to working on developing my game.
either application is a .GIF (graphical user interface)\ 1: convert your pics to .gif either en bulk or 1 by 1 and save as .gif 2: use a gif maker or blender and save/export as gif, set your speed in millisecs (like 25fps first) 3: Test and adjust to suit good luck
I want to make certain types of images (hd) and also short clips (less than 30 sec), but feel overwhelmed starting anything, seems like there's so much to operate on both Gimp and Blender.
