![]() ![]() The loop playback has become seamless (thanks to pre-caching next frames in a non-stop manner).The one I especially like - texture updates are done now in a background thread - main thread is unaffected by playback.Next, I’d like to list what new features were added to the vvvv’s Demolition Media Hap Player: Hopefully, GPU accelerated Hap R encoding will be available somewhere soon and then it’ll be possible to quickly prepare new footage versions for playback.ĭemolition Media Hap Player for vvvv beta/gamma supports it already for some time, and you can use Hap R in both RGB and RGBA modes. It’s nice not only because it’s the first and the only one to support Hap R, also it improves Hap and Hap Q quality compared to the community encoders. You can use it for either Adobe Media Encoder or for After Effects. ![]() The support for encoding was shortly added to the amazing Jokyo Hap Encoder - which is another recent addition to the Hap ecosystem. Hap Q is on the left and Hap R is on the right. ![]() I recommend going to the maximum zoom level using mouse wheel in some area and then moving the comparison slider / pan using the mouse. The borders are much smoother and clearer on the second image.įeel free to play around with these three side by side interactive image comparisons: Leviathan video, Fireworks video, Jokyo test with alpha. The white gradient is much much smoother on the right, and so is the background area. Here is a comparison of some rendered content encoded with Hap. It also supports alpha-channel transparency at same compression rate (reserving some color bits to store alpha information). Hap R encoding right now is slower compared to Hap Q, but decoding is almost as fast as Hap Q and we’re getting rid of the annoying artifacts like banding on color gradients or blockiness. And that’s given that compression ratio is same as in DXT5 used in Hap Q (8:1). It uses internally high quality BC7 compressed textures, and makes videos quite close to ProRes. In the mid-2020 a long-awaited Hap R codec was added to the hap specification. I will try to put the information all together in this blog post. Sadly, there is not a single website with all these updates (though there is an official website now). There were multiple important things happening in the Hap GPU-accelerated video playback codec world recently. ![]()
