| Post subject: | Can you speed up the tracking process? |
Currently it is taking me about 17 - 20 frames a second to track a 3 camera 10 second take which is approx 90-100 minutes. Can it get any faster? I had read it was 5-10 seconds and was expecting less as my laptop is fairly beefy. What portion of the computer does the tracking processing use the most? CPU , memory, vid card? edit... I realize the tracking resolution can be set to low(faster) which brings it down approx half the time... but it still is about 9 seconds per frame which I find slow. Thanks |

Hi, You stated 17 to 20 frames per second, which is actually blazingly fast, so I assume you actually meant 1 frame per 17 to 20 seconds, which indeed would be slow. :) I suspect the slowness you see is due to an insufficient graphics card. Tracking and calibration speed is largely dependent on the GPU speed of your graphics card. I have a fairly modest Nvidia GTX 460 and currently get about 1 frame per 0.67 seconds or about 89 frames per minute. That's not the fastest time you'll here about here but it's quite good and certainly fast enough for production work. You can find benchmarks here: http://wiki.ipisoft.com/index.php?title ... ccessories Scroll down to video cards for the list. If your computer does not have GPU (for example, it's a laptop with stock Intel Graphics) then tracking and calibration performance will certainly be disappointing. Many users who use a laptop to capture their motions, will transfer the data to a desktop computer with a good graphics card and do the calibration and tracking there. (FYI, I used to do it this way. Now I capture and track using the same desktop computer and my workflow has been more reliable this way. This is just me though; you may find a different workflow more fitting depending on your hardware and shooting location.) Hope this helps. G. |

thanks for the response... haha.. yes.. you are correct with the time... 17 sec per frame. when I turn the tracking down I get about 9 sec per frame. I have an Nvidia Geforce GTX 670M / 3GB GDDR5 16 GB ram yes it is a laptop |

Maybe iPi Mocap Studio is running on integrated Intel graphics, and you should manually switch to NVIDIA. See this post for detailed explanation: http://forum.ipisoft.com/viewtopic.php?p=11919#p11919 |

Wow--something must be off then. Technically, the m (mobile) series may not be as fast as the desktop versions but I would think the tracking performance should be pretty decent with this card. I don't have any experience with this card but, IMO, 9 seconds per frame seems abnormally slow for the specs. I assume you're using the latest drivers too? Which OS? Sorry, I'm not sure what else to suggest. Hopefully somebody from iPi Soft will join in to help. G. |

That's a good suggestion from vmaslov. While I don't run iPi Studio on my laptop, it does have switchable graphics. Normally, I run in Nvidia mode but when I'm on battery power it switches to Intel Graphics by default. (Intel Graphics has very low-power consumption at the cost of performance.) I have the option to switch to Nvidia while on battery but I do this manually. Optionally, I can force the laptop to always use Nvidia regardless of AC or battery power through a setting the control panel. As vmaslov suggests, you may want to check which mode your laptop is currently running in. Hope this helps. G. |

yah apparently switching between the vid cards did it. I am now getting on avg about .4 sec per frame for processing dual kinect and about .6 sec with 6 Sony cams. thanks for the help guys. |

Those are very good times! Glad you got it working. :) G. |
