Audio only question
on Sep 30, 2010 at 7:14:49 am

Does the Ki-Pro need to be fed a video signal in order to record an analog audio signal? In other words, if I needed to record a narration in studio through the XLR inputs could that be done (only audio - no video?) And if so are there any "gotcha's" in using the Ki-pro as an audio recorder in a pinch?

I would imagine it does as there's no way to 'turn off' video recording and will throw an error about genlock if there's no video. That being said, the signal could be anything as long as it's stable. Your "audio files" would acutally be ProRes video files with embedded audio that you would then have to strip out.

Kim and Jeremy,
One way to record audio using the Ki Pro without using an input video source is to turn on the Video Signal Generator provided in the Ki Pro CONFIG menu. This will produce a video test pattern, like color bars, and then you can input your audio source via the XLR inputs. The resulting file will be color bars with your desired audio recording.

Jeremy is correct though; you need to produce some sort of video signal to go with the audio as the QuickTimes produced by Ki Pro always produce audio, video and timecode tracks. The use of the signal generator would seem to be good solution for your needs in this case.

Hope this is helpful information.

Yes that's very clear. We're looking forward to having a Ki-pro in our facility very soon. Thanks for the response.

Of course, why didn't I think of that? ;)

Thanks Jeremy. I guessed as much. I've asked for a unit to try.
Cheers!
