PNGs Export not retaining Transparency

I have a PNG image sequence, I am applying Frame Interpolation 2x slow-mo.

When I export the result as PNGs, the PNGs do not retain transparency, instead, it is exported with a black background which is unwanted.

Is it a bug or is there some setting I am missing?

Unless something has changed that I’m not aware of, I don’t think TVAI supports alpha channels.

They would have to start AI training all over again to get alpha channels working in TVAI. I’m willing to bet the black does not come out to be pure black after being processed. Same thing would happen with an alpha channel.
