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.
