I’m currently in the process of re-downloading everything on x265 because of the smaller files sizes. Whats do you guys think? Also has anybody experience with Tdarr?

    HEVC 10 bit in order to reduce banding for animation, especially during dark scenes. I know H264 Hi10 exists, but it has poor hardware support, so using HEVC 10 bit is the best option (I don’t own a single streaming device that supports HW accelerated Hi10, besides my PC). Also, an added benefit is reduced file size. I find that doing my own encodes is very rarely worth it, but when I do, I use FFmpeg in the CLI and not tdarr.

        Banding is that annoying color gradient you see sometimes in dark scenes.

        Example

        On the left is 8 bit and on the right is 10 bit.

          Hold up. That entire image is 8-bit. It’s a JPEG image. JPEG can’t encode more than 8 bits per channel. Nor can most displays, including mine, display more than 8 bits per channel. And yet the left half of your image exhibits far worse banding than the right half.

          The left half looks more like 5 bits per channel rather than 8. You’d see that kind of banding in gradients back in the days of Windows 3.1, when 16-bit color was common. (16-bit color uses 5 bits each for red and blue, and 6 bits for green.)

            It’s an exaggerated example to demonstrate the concept of banding more clearly, not a technical breakdown.

              Then it should be marked as such. It’s highly misleading to anyone who doesn’t know better. Again, you’re demonstrating the difference between 5-bit and 8-bit color, not the difference between 8-bit and 10-bit color.

                The purpose of the comment is to demonstrate banding. The only reason I marked it in bits is to show how banding can be reduced in video encodes by increasing the bit depth, not the specifics depths itself, it’s not a technical write-up.
