The sensor size is the limiting factor here re: noise performance and dynamic range, but the iPhone does better than most with some ML and other “computational photography” tricks for denoising that other small sensor cameras don’t have. And ProRes is a great codec that doesn’t really have compression artifacts at high bitrates.
It’s not going to replace your Alexa or even full frame dSLR but can be useful and is a welcome evolution.
- sudosysgen 3y agoProRes is actually worse at the same bitrate when compared to H.265 or AV1, and sometimes even worse than H.264. The advantage is that it's easier to edit because it's all intraframe, not that it has higher quality - it's worse. Even intraframe HEVC is going to be better than ProRes. H.265 really is going to give you consistently better pSNR and SSMI than ProRes, and that shouldn't be surprising - interframe compression is better for quality. The only advantage here is slightly better denoising, yes. But denoising doesn't change the dynamic range limit, it just hides the noise visually. The SNR is actually going to be lower.
