Video format with dynamic resolution Are there any video formats that change resolution per frame and with different resolutions at different parts of the screen?

All videos I know today they have fixed resolution.

For video blogs I don't need the highest resolution when I am only talking with frame on me. Selectively I would like to have the higher resoltion on photos I am showing and short clips I attach.

Why I want it?


4+K videos would globally kill any internet connection,
Storage of 4+K unoptimized videos take huge disk space.


When I present a photo I don't need also to copy the photo to each frame of video where it is visible.

The closes thing is presentation like *.ppt . But it is far too complex to play, create(with sound all the time) and stream. Maybe I only need some smart video compression tool?
You can't get "dynamic resolution" because essentially that would mean that some of the time you used a 4K display (for example) to show a 2160P image and some of the time you displayed a 1080P image by pixel doubling - so either way it's 4K but what you could gain (IF there were such a Codec) is an increase in the compression, and that's where you should look.

The h265+ Codec developed by HikVision analyses the image frame by frame and decides what is important and what can be compressed to a greater extent, relying upon prior frames to have the data to 'fix' where the extreme compression was used - it can be decoded with a standard h265 (non plus) decoder.

Here is a quote from their Website: "The average decreased rate between H.264 and H.265 is 47,8%. When applying Hikvision H.265+ the decrease rate increases to an average of 83.7 percent.".

As far as I know it's only available as Hardware in HikVision's cameras, if someone knows where there's an Open Source version of h265+ I'd sure like to know - thanks.
