GPIO delay

[Camille Herren]

We're doing a moco go-motion shoot starting this Friday and was wondering how long the delay is from once the RED receives the signal via external trigger to when it actually takes a picture.

Any info would be much appreciated.

Thanks

Good day . It is very important information for me to . We have same problems with Moco . Our Moco can send start signal and begin action with no delay . but record will delay . You can try to do it like this .

Connect Signal from MOCO to Hooter , (1 sec) , peeeeeeeeeeeeeeeeeeeeeeeep
Record sound in Camera
Then just synk sounds Same effect as it is with slate

Hi Vigen

not sure we're talking about the same thing. go-motion is a form of stop frame animation. there's no sound involved and it's one picture at a time, like timelapse. From what I've learned so far unlike stop-motion, go-motion triggers the camera to take a picture while moving so you get camera motion blur. the moco rig backs up to give itself enough room to get the motors up to the desired speed and then, when at that speed, triggers the camera. there's other names for that too, but go-motion is what I know it as.

You could test it yourself by shooting a timecode slate or more accurate time display synced to the moco gpio trigger then calculate the offset.
