io HD noob
Hello all,
My colleagues and I are video novices–we’ve participated in FCP workshops, so we’ve got a good understanding of it, but we are weak on equipment.
We just purchased an io HD and I am trying to learn out to operate it. Our primary camera is an HVX200AP P2. I’ve connected it to the io HD via the component output. I’m able to use the “easy setup” settings in FCP and thus control the io HD.
My main issue at this point is that the signal (from the camera to the io hd) is 60 fps and I want the captured footage to be ProRes and 24 fps.
Any help is greatly appreciated.

Unfortunately with that camera, the only available connection is analog out. Since no information is carried over the analog signal about pulldown. the ioHD cannot remove it. If you have a camera that sent information via SDI, the ioHD would be able to remove the pulldown upon capture.

Ahhh, I see. That makes sense, thanks Jeremy.
Well, can I shoot 720p, 24fps, copy the footage to the Mac and somehow use the io HD to convert all the footage from DVCPROHD to ProRes? Rather than using Compressor.
That is, is it possible to use the io hd to encode files from disc rather than from a camera?

The ioHD dies it’s magic through baseband video connections. It wasn’t designed as a transcoded for existing video, although that had been requested frequently.
With that particular camera, you could shoot at 720p24 over 60 and capture and edit @ 59.94 fps. It will retain the 24p look, but the footage will have pulldown in it. An hpx170 with SDI would also solve this problem.

So, it sounds as though we don’t have a use for this ioHD as long as we’re shooting with this camera that lacks the digital (HD-SDI) output.
Correct?
It was recommended to us, but we clearly didn’t know enough about it, and I think the person recommending it wasn’t clear on our equipment. I was just hoping it would be a timesaver with ingesting all our footage as ProRes so we’ve be ready to edit in FCP without constant rendering.
thanks for your help.

Correct?”
Like I mentioned, you can use it to record 720p59.94 with the 200, and you can also use it to monitor your FCP timeline to a broadcast monitor.

But, if I want to do 720p24 with the hvx200, I’ll simply have to log and transfer and therefore bypass the ioHD, right?
In my testing, I’ve set the camera for 720p24, but regardless of the settings, it always comes in at 59.
94–I guess it’s due to the analog signal and not having the pulldown in place.You aren’t saying there is a way for me to get the 24fps film look with this camera and the ioHD are you? ‘Cause, ultimately, that’s what I’m trying to achieve.
And yes, I’d love to use the ioHD to view our timeline on a monitor, but haven’t figured that out yet.

If you need 24p files, yes. You need to shoot 24pN on the camera.

Yes, set your camera to 720p24 and record @ 59.94. This will record 24p with progressive 3:2 pulldown. It retains the 24p look, you will just be editing on 59.94 timeline.

OK–I think I see now. So even though all indications are that the “stream” into and out of the ioHD is 59.94, and my footage in my bin is 59.94 and the timeline is 59.94, I can see there are duplicate frames in the clip and this is the pulldown that will give me the “film” look.
Correct?
How does this compare to 24pN? I don’t quite understand this setting. If I’m not overcranking or undercranking, would I use it?
I apologize for all the questions–this forum has been a huge help.

[Scott Phillips] “I can see there are duplicate frames in the clip and this is the pulldown that will give me the “film” look.”
The “film” look comes from 24p, not the pulldown specifically. The pulldwon just pads the material so it’s viewable/playable over 59.94 baseband video.
[Scott Phillips] “How does this compare to 24pN? I don’t quite understand this setting. If I’m not overcranking or undercranking, would I use it? “
24pN captures just the 23.98 frames you need. So instead of the files being 59.94 (24p with pulldown), they would be 23.98 and you’d edit on a 23.98 timeline. If your camera had HD SDI, you could capture 23.98 as the ioHD could remove the pulldown on capture.

OK–thanks.
So, if I proceed with 24p footage in a 60p timeline, when the project is completed and I’m authoring a SD DVD, Compressor will analyze what I send over from the timeline and it will pull out the duplicate frames and get it to the frame rate required for a DVD?
Or would I need to reverse telecine?
On another subject, if I use the ioHD to display my timeline on an external monitor, I need to output from the Mac via DVI or minidisplay or something, right? The FireWire connection between the ioHD and the Mac isn’t used for this purpose is it?
