HAP codec usage

Has anyone been encoding their videos with the HAP codec? Just curious if you are experiencing what I'm experiencing:

- I've take a 30MB h264 file for a sample test
- I did the regular HAP codec. It turned it into a 500MB file
- Used HAP Q. Turned it into a 1GB file!

What is the purpose of this codec? I thought it was meant to be an optimized codec. These files are huge. I'm just not sure why I would ever use this codec, if my H264 files are already super optimized. :D

. if i understand HAP correctly, it's optimized for playback/scrubbing video (and can also do an Alpha channel when Modul8 implements that feature)…

. H.264 is decompressed by the CPU - so, if you're running a lot of videos, effects or other applications - playback can suffer or other programs will lag…

. Modul8HD is supposed to fix that when it's released.

Low CPU and GPU offloading is why I used HAP..

I had plenty of SSD space for the larger files (Raid 0 too!), 6gb VRAM and experienced much lower overhead running more layers of HAP vs PhotoJPEG

That being said.. with much larger file sizes, and Modul8 being a 32bit Quicktime app.. that 4gb of usable ram gets used up awfully quick... so there's some performance issues I experienced there, but was able to remedy it a little with a RAMDisk and would copy HAP media files to the RAMDisk and playback would be improved.

Hi there,

I have some good news, the upcoming version 3.0 resolve the performance issue using HAP.
The performance are going to be amazing you can play up to 8K movie!

The Beta version will be available in the next few weeks.
