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.
[Scott Phillips]"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."
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.
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.
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.
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.
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.
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?

This might get a little but complicated for you if you are new to video, but since your 60p footage is 24p with pulldown, once you make a 29.97 SD DVD, your footage will retain the 3:2 pulldown it will just be interlaced. No reason to remove the pulldown. Make an interlaced 29.97 DVD and you will be fine (24p look will still be retained).
[Scott Phillips]"The FireWire connection between the ioHD and the Mac isn't used for this purpose is it?"
Yes it is. You install the AJA drivers and that will in turn install the necessary parts for FCP. You take the video out of the ioHD and in to your video monitor and use the AJA easy setups to monitor your footage. There's a manual that explains that in further detail if you need it. You need a video monitor, not a computer monitor (unless you are using the HP DreamColor, which is both).
I did install everything from the AJA disc and I have printed the included manual, but I cannot seem to get anything on the external monitor. It works fine when the camera is attached to the ioHD and FCP is capturing.
But, I cannot go from the Mac to ioHD to monitor. I've tried altering the AV settings in FCP, but cannot seem to get it to work.
Is there some other manual you are recommending, or were you just speaking of the one on the AJA install disc?
In regards to audio. If we use the setup as described (capturing the live feed directly into FCP via ioHD), how should we handle the audio? I've been testing with the built-in mic on the HVX200, but no audio is in the clip after capture. Naturally, I have an analog connection from the camera (red and white RCA) to the ioHD, and I set the control panel for audio to be analog, but still nothing.
Is the proper workflow to skip the camera all together and run audio from external microphones to the ioHD using the XLR connections? I guess "log and capture" will bring in that audio along with the video and put them in the clip together?
[Scott Phillips]"Is the proper workflow to skip the camera all together and run audio from external microphones to the ioHD using the XLR connections?"
If you have line level out of your mics, yes. If not, you should put a mixer in between the microphones and your ioHD, which is common practice. You can then loop the audio out to the camera for backup (if you are recording to P2 as back up).
Hi again. I have a little 4 channel mixer now and when I hook up headphones to the mixer, the audio sounds as it should.
But, the audio being captured by Final Cut is barely audible--even with the mixer all the way to "11" and the gain in FCP cranked up.
Does it mean I need an amplifier also? I'm surprised that I would need one in addition to the Io HD and the cheap mixer. Perhaps in my haste to get the mixer, I should've looked into something with additional power.
Well, I have the mic connected to the mixer via XLR, then another XLR goes out of the mixer to the Io HD. And, again when I connect headphones to the mixer to "monitor," it appears to be fine. But somewhere after the mixer, the signal breaks down and when watching the audio meter in the log and capture window, the meter responds, but doesn't get very loud--its peak never reaches yellow or red.
And the meter in the front of the Io HD also doesn't get very high (loud). The Io HD control panel on the Mac is set for analog audio input. I tried a different XLR cable just to troubleshoot, but it had the same result. I also tried a different Mac with FCP and had the same result there too.

Have you tried turning the master up on the mixer? You aren't sending enough signal to the ioHD.
Yes, it definitely seems as though there isn't enough signal making it to the Io HD. But, I do have the mixer maxed out--I can hear a lot of hiss and ambient noise with it cranked up, but very quiet when monitoring with FCP.

Seems to me you have a mismatch of settings somewhere. Does your mic need phantom power and are you sending line level out of your mixer? Have you attenuated the channel with your mic?
I'm testing a wireless lavaliere mic--I've also tested a Shure SM7B with the same results--and the transmitter is plugged, via XLR to the "line 1 in" on the Behringer. I have the Gain and the Level knobs at half-way between min and max. I have the main mix slider around -10.
I've plugged in headphones to the "phones" jack to monitor and it sounds as I expect it would. I can clearly hear myself speaking as well as lots of ambient noise with everything set this high. The meter on the mixer will register -20, but never up to 0 or closer to being "clipped."
From the mixer, I have two 1/4" to XLR cables that go from the "main out" to the "in 1" and "in 2" XLRs on the io HD. As mentioned before I also have analog video from a Panasonic HVX200AP connecting to the io HD. I plug in the headphones to the monitor RCA on the io HD and it is much quieter when compared to what I hear when monitoring on the mixer.
Then, naturally I have the io HD connecting to a 27" iMac via FW 800. I'm using the easy setup in FCP=AJA ioHD 720p 59.94 Apple ProRes 422 (HQ), with audio settings of 48 khz, 24-bit and "config" set to "channel grouped."
When I use log and capture, I go to the clip settings, where I monitor the sound there (Preview is checked). And, just as it is monitoring on the io HD, it is much quieter.
Once I stop and review the footage, the audio waveform barely registers anything and my sound is around the -60 on the meter.
So, it seems to me that something is happening at the io HD.
Hope this is helpful--please let me know if you need anymore info on the setup.
Yes, I haven't maxed everything, but gain, level and mix is all just shy of max and it is registering on the io HD meters, but not very high. Just like FCP--it is moving, but not anywhere near where I would expect.
