Video format with dynamic resolution?

Question

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?

Hi there,

The solution you are talking about does exist, however it is likely more complicated than is helpful to you. The way that YouTube switches between different resolutions is through what is called "adaptive bitrate streaming." The long and short of it is, they have various versions of the same file at 1080p, 720p, 480p etc., and when you internet is too weak it will switch to a lower resolution, and therefore also lower bitrate, file. This is a complex and important streaming tool for someone running a professionally streamed production. However, I don't think there is a way to do what you are suggesting manually. It is possible that there is a streaming tool that exists that offers these options, but I don't know of any fixed vod formats that will let you scale up and down based on the part of the video.
