does not upload

Hey, I know this hasn’t been supported in some time, but hoping perchance I could get some help, or a point in the right direction.

Everything appears installed correctly, FFMPEG detected. etc.

but when I do to upload a video, the uploader just spins as says please wait your video is being uploaded.

wondering where I should be looking, perhaps a permissions folder? does this upload to a temp folder, or straght to the standard WP media folder.

thanks for any help ??
