However, if you add a USB capture device or use the Facetime HD camera, you should get these prompts the first time. If you are using Blackmagic Decklink or UltraStudio devices, you may not be prompted to grant permission. Not all video inputs require permissions. In order for this process to work properly, you need to turn the Audience and Stage outputs off. You can feed the audio out of the IPad to the camera or system yiu are testing audio input to check audio delay also.ProPresenter 7 on Mac may ask you to grant permission to access the Camera and Microphone when attempting to use a Video Input for the first time. Then On a frame grasp from,the footage, or in camera playback you can see what the frame delay is between the direct shot of the IPad and the camera output monitor display next to the IPad. You can measure the delay (latency) by shooting a clip board or better yet, a digital Culp board app on an IPad, and place a good known monitor (with low latency response) next to the IPad in the same shot, dįeet your HDMI or SDI camera output to this monitor, and record while setting off the clapboard and let IPad frame time code counter run for a few seconds. So like BM, some Canon cameras can have more or less delay from one model to the next. So video processing delays accross different cameras does vary from one model to the next. You could potentially use a video delay device to compensate for this and increase the Micro Studio camera to a three frame delay. This does make the combination of both cameras unsuitable in a studio environment. The Micro Studio Camera 4K has less then a 1 frame delay. This hasn't changed with any firmware updates to the camera and is still true at 1080i50. I can confirm that the URSA Mini 4K does have a 3 frame delay on the SDI output. Add in scaler and projector latency and you can be in a world of hurt. The net result is the same though, if you have cameras with some latency, it gets compounded by the TVS, and can be an issue for iMag. I've never noticed delay just looking at the camera on an external monitor via HDMI, so I'm not buying that there's 3 frames of delay there, MAYBE 1 frame. I always assumed it was the synchronizers and processing in the TVS. Audio is 5 frames early compared to picture. Audio from camera is in sync with itself on program output (though both are delayed ~ 5 frames).Ĭanon HFs20-> TVS HDMI input 1 ->Program output (monitoring audio mixer on external TVS input). So you think the cameras have 3 frames of delay on the HDMI output? Is that common? I'd always blamed the TVS, I guess some of it could be the camera, but either way you end up with 5 frames of delay on the output, and have to offset the audio to match.Ĭanon HFs20-> TVS HDMI input 1 ->Program output (monitoring audio in input 1). The Pic recorder even has this feature added, so can sync the processed video and audio from the camera to the direct audio input connection on the Pix. In broadcast this is not a problem, as the audio is resysc'd (delayed) to match the video. By the very nature of single sensor digital cameras that have to process the video data from the sensor, you are going to have a delay from the camera, then add any additional video signal processing delays between the camera output and the switcher output, it adds up quickly. I use a Video Devoces Pix pre order, connected to a camera via SDI, with audio connected directly to the Pix, and you can see the video delay coming out of the camera, between the direct unprocessed audio and the camera's processed video signal. What camera are you using? Any other devices between the camera and TVS? Some cameras, including the Irsa Mini, have a noticeable (2-4 frame) delay in their video outputs, cabins this with the TVS delay, and you get your 5 frame delay between direct audio and the processed video.
