Would love to see the Star Trek Voyager: Enhanced 4K project. Please PM to provide the download links.

Somewhere I read that this project applies SDR, not HDR. If you ever decide to apply HDR, keep in mine the HDR10+ is way better, because it applies to every scene, meaning it changes for every scene the grading, compared to applying the same grading for the entire whole video.

For me, when watching the difference between SDR and HDR, it always come down to the visual experience. SDR has less transparency, it is as if your viewing a slight white milky film over the video. When viewing HDR this white milky film disappears, so you see the image without looking through a film coating. The blacks look more black, the colors stand out more, becoming more vivid. The overall viewing appears more lifelike.

But, HDR also has it’s problems, like the dark scenes becoming way to dark, loosing important details in the shadows. The HDR day scenes usually look great in comparison.

Unlike SDR, the HDR has many different gamut color profiles to select. Smart TV’s tend to support broadcasting like BT 1886. Blue-ray BT 2020, older SDR BT 601 and 709. All this sounds confusing when you just want to watch without adjusting options. If you watch a HDR on SDR display, you will notice the color of the video bleach out, looking like the color saturation was turned down. Some software applications like PotPlayer can offer some relief to adjust the differences, but not in every situation.

A newer codec AV1 is replacing HEVC. How much better would this newer codec be for upscaling 4K or 8K? Has anyone tried upscaling with AV1 in HDR+ or SDR?
