batch Hap video convert - Creative COW
For situations where a computer can't handle playing back movies because the CPU usage is too high, using Hap may make it possible to reduce the overhead of playback. You can read more about about the benefits of using Hap in our blog post featuring side-by-side comparisons against other popular Mac VJ and real-time video codecs.
Lastly, it's important to note that you'll only benefit from using Hap if your video application natively supports it: if you aren't sure, check with its developers before transcoding your clips.

Converting movies into Hap. The newest AV Batch Exporter for Hap Alpha has similar image quality to Hap, and supports an Alpha channel. If you can live with the command line interface which I personally like better and better the more I use it , ffmpeg would be my recommendation. Since Hap files tend to be large, a fast disk is probably one of the most important aspects when encoding Hap movies.

It is also quite easy to do batch encoding in ffmpeg by just using a regular. But if something is not correct like a missing or bad image in an image suite , FFMPEG will just raise a warning in red and give you a file, you can think the video is ok but an image is missing and you could see it when playing back in Watchout. So be careful and read the logs. Concerning the encoding time, my thinking is your resolution is about 4 times 4K, why should it be quicker than 4 times encoding a 4K video or 16 times encoding and HD video?
When is it appropriate to use Hap?
I don't know if you've come across this yet, but I've been using it on my last project in After Effects. It's called Render Garden. It uses all the cores, ffmpeg as a backbone with an after effects interface, you put your files in the render cue, and plant a garden that runs in the background. For very large movies high resolution, that is it makes sense to use the -chunks n argument to enable multithreaded decoding, where n is the number of chunks to use.
It never makes sense to use more chunks than there are cores in the target display computer. As each additional chunks adds a very slight overhead in the form of decreased decoding speed and larger files, it is generally a good idea to keep the number of chunks as low as possible. I tend to avoid command line interfaces whenever I can and look for good graphical user interfaces.
Batch encoding, watch folders, HAP support including chunking and pretty quick with control over multi thread encoding are all useful features I use a lot. The Save as separate audio files is particularly useful since HAP with audio is currently broken in 6.
