    Hi all, so I need a software which will turn pre-rendered frames (86) into a video but keep the transparency so I can overlay the video onto another.
    The images(frames) are PNG and I dont have a preference for the video format used.

    Which software will allow me to do this?
    I don't have a budget so please tell me the best one.

    Thanks,

    You should have a preference, because you would want a format that is compatible with whatever you're using to perform the overlay.

    That will determine what your options are

    So what are you using ?

    Do you even need to do this ? For example, most video editors can import image sequences

    Do you want an overlay video that is entirely semi transparent or a video that has certain backgrounds that are completely transparent?

    Very simple with FFmpeg. Your filenames should contain a sequential number to indicate ordering of the frames. Then,

    ffmpeg -i myimage%d.png -c:v huffyuv myvideo.avi

    will produce a losslessly compressed video with alpha channel. %d is a placeholder for the number in the filename.
