Hap Codec Support?

jhoepffner

Hello,

I change my mind, the hap alpha for 3D incrust (from Cinema 4D) or blue screen composite is very good.

it is GPU accelerated codec that works in accelerated mode in the specific app, that supports it. Same procedure as Resolume and DXV codec. However the implementation is open source so any app can be made to support the codec fully.

You may want to try your clips in ProRes and Hap in latest VDMX.

BTW VDMX will run on your mac the same as Isadora. You only can not save anything before you buy it.

Vanakaru is right.... you need an app that can take advantage of the GPU feature before you'll see anything happen. But from my preliminary reading, it seems clear that I should make this happen in Isadora.

Best Wishes,

From the VDMX Forums;

"The file sizes for Hap movies are going to be a lot bigger than P-JPEG, the advantage is way lower CPU usage, if you've got a slow disk, it might not make sense to convert your movies right away.

Also note, if you've got movies that contain subtle gradients or fine details that need to be preserved, try using the "Hap Q" codec instead, the quality is a lot better in these situations!"

this would be real nice. It's from the guy who co-wrote syphon with vade and they are both extremely talented coders

In Isadora I would guess that one would only really enjoy the benefits of HAP when working entirely with Core actors. Mark, is this correct?

For the moment that is true. But once I get the FreeFrameGL support out, then it will be more generally important.

Best Wishes,

This is terribly exciting! I've started playing around with VDMX lately, and this performance is simply breathtaking. 9 HD Videos full 1080p playing back at 30fps is something that only large scale media servers have dreamed of before.

As Isadora is my tool of choice for theatre work, I look forward to seeing HAP in Isadora as well! Keep up the good work Mark!

This sounds great.

Yes indeed!

BTW I have been experiencing some nasty artifacts in light areas when encoding contrast footage.

Have you been using the higher quality codec or the standard hap?

vanakaru

@DusX

Actually both Hap and HapQ. I have footage of passing treetops and cloudy sky. Sky looks like full of bugs flying.

I wish that the codec allowed the compression to be set.
I did not like this about DXV either.
