How to encode videos

To play videos you would need to re-encode them to Hap first
Encoding tips (pdf) Additional
Encoder patch (ffmpeg binary included)


  • Q: How to achieve the maximum performance out of the player?
  • A: Try encoding without 2nd stage compression. You can save CPU time with that, at the cost of higher data-rate (it also depends on the content) -- your SSD should be fast! Add "-compressor none" to the FFmpeg arguments. I've managed to play 10k@50fps with this approach on my laptop.
  • Q: I want to drive the playback with the frame index/LFO/external clock/sync playback on several machines
  • A: There is such plugin version, but it's non-public. Write me an e-mail if you're interested!
  • Q: What about reverse playback
  • A: You would need an external clock plugin version for that (see the previous question)
  • Q: I've exported the video from After Effects with audio track. It isn't being played nicely by hap player
  • A: The audio from AE is heavy. Please re-encode with FFmpeg using the "-vcodec copy" option (will only process the audio stream, leaving video frames as is). It will be played fine then.
  • Q: I have a Windows 7 machine, and all the hap player nodes are red.
  • A: You're in a bad situation. Try 64-bit plugin version, or upgrade to a newer Windows version (8.1 is enough)



  1. Experimental support of non-multiple of 2 video resolutions
  2. Accurate computation of the current frame index
  3. The image queue size was increased to 10 frames/100Mb, which gives slightly better performance in some cases
  4. Don't seek to the start when the playback is finished
  5. Loop pin of HapAudioClock now accepts a boolean (on/off)
  6. Fix Opened/Playing outputs of HapState: don't reset to false when opening a single video from the input Path spread
  7. HapReaderNode: make number of ouput slices equal to maximum slicecount of (Path, Open) input spreads
  8. You can open one video multiple times, or open a video using arbitrary Open slice, without opening all the slices prior to it in the Open spread
  9. Now works with vvvv 45beta34.2

Hi, is there any plugin or codec needed ?
I can not open any mp4 or mov video...

Aurel To use this player, you need to convert your videos to Hap first! Take a look here how to do it: demolition-media-hap-player#How to encode videos

how do you play audio as well with this goody ?

Im playing around (testing) with this plugin. When i load multiple footage (~20 full HD) using Dir, the CPU usage jumps up to 100%. Got 1080Ti working as a GPU but this only goes 30%. is there a way to avoid High CPu Usage?
