I'm pretty sure this is a BS marketing claim. Their site mentions "We compress raw recording data up to 3,750x times". This is just the regular hardware supported h.265 codec that comes in every mac. They're claiming "up to" because there are compressed frames such as B-frames that are the smallest frames which can typically be as small as 2000 - 4000 bytes. So if you look at an uncompressed 4k frame (3840 pixels * 2160 pixels * 10 colordepth)/ 8 = 10.368 MB. So an uncompressed frame of 10.368 MB / 2700 Bytes (H265 B-Frame) will give you ~3750X compression.

I could be wrong but I'm skeptical about this claim because video compression can't be done so simply just by creating a new algorithm and writing it in software. Especially the newer codecs such as h265, h266, and AV1 must be in hardware or else it would be too computational heavy and your device will just choke up trying to spend so much cpu time compressing when you're trying to run other processes.

Also if it was their own video compression, they would have to write their own decoder for their own player for every device. That is way too much for a start up to take on. It just smells like BS to me.

I believe it's because they are using middle-out compression.

I think they must be using similar AI / ML stuff to this recent work for audio https://arxiv.org/abs/2210.13438 but for video

Agreed. The compression seems pretty impressive.
