Turning images into a video
In FastFlix it is possible to use encoders that are in ffmpeg like libx264 and libx265 to turn a directory full of image into a video.
Instead of loading through the normal source button, you will need to go to tools > Concatenation Builder
The directory with your images may appear empty, but that is just a quirk of the underlying libraries of this software.
Make sure all the image files are the same dimension, and that there are not extra files loaded in from that directory.
Keep in mind if you have over 100 files, it will skip this step and order by file name. So make sure numbering is padded, like image_00001.jpg, image_00010.jpg not image_1.jpg, image_10.jpg
Make sure to manually specify a frame rate you want for the video in the Advanced tab (I set input and output to the same), and change vsync to constant frame rate cfr.
