Looking for a software/app for specific wallpaper animation

[Vinny]

What i am trying to obtain is pretty simple but might turn out to be more complicated than it really is:

I basically want to have a very high quality animated phone wallpaper without the use of a gif file (for quality purpose)

this is approximately the effect i want to obtain: [hide=gif][/hide]

As you can see the first black and white image is displaying for 2 seconds (as initially projected, but the conversion to .gif of course fucked the timing up) and the negative of the same image is there for 1/30th of a second to create a short blinking effect between the two images
This is a view of the project in sony vegas


The problem with using a gif is the quality becomes trash whenever you convert it to a reasonably sized file (i'm looking to use these both images at their full 1440x2560 resolutions)
[hide=both full resolution pictures][/hide]

I literally have no idea what software/app i should be looking for therefore i'm asking you if there perhaps is even a built-in android feature that i may have missed to make something like this, or can anyone lead me to an app able to create a precisely-timed animated wallpaper?

thank=)))))))

Ran it through Adobe Premier for you. Uploading to gfycat now, dunno if its what you wanted though.

Edit: https://zippy.gfycat.com/HoarseSelfreliantAlbacoretuna.webm hows the timing?
