When working a film convert it from movie format to a bunch of stills (you can render it so. I think andrew has a video on this). Make sure to do this in a unique directory because you get about 24 pics per second. The format for these pics should be png or if you want to do a lot of composting then OpenExr is the way to go but the files are bigger and might slow down and older machine. Think of it this way. PNG has 0-255 for each color of each pixel, whole numbers only. Try multiplying that by .1 and then by 1000 a few times and see what you get. The other system uses floating point math for each dot and that keeps it high quality. PNG works but don’t expect much in the way of high quality compositing.
Look at the screenshot I attached above. I want you to look at the left sidebar. The #01 “Getting Started” video is what I just walked you through. You can see there are more video instructions. The videos are between 2 and 5 minutes long each, so it doesn’t take long at all to become acquainted with the software. The 5 additional training videos include the following topics.
This tool is way ahead of the current OpenSource alternatives. Whilst Blender is a 3D tool with a video editor, this is a video editor with a 3D modeler and it does video editing very well. Motion stabilization, transitions, color grading... all shine. If you don't mind using a closed source application, this is the best free (and possibly non-free) video editor as of 2019. See More
Vidnami promises that you can “Create Stunning Videos Fast” with their app. You can use Vidnami video creation software to turn articles, blog posts and shorter pieces of content into videos in minutes, or so the creators claim. I’ve spent a lot of money having freelancers create videos for me, so I figured I would give Vidnami a shot.
