Screen Capture with DP

[labman]

Good catch stubbs. I will try that out and see what it does. I sent RogueAmeoba a tech note last eve, and they replied that they are unaware of any apps that it won't work with. But of course DP talks 'directly' to the physical interfaces (HD192's etc), as opposed to OS X, so perhaps it won't work. Will give it a go.

The concept of being able to save various routing for differing screencasts is appealing.

Doesn't DP talk to CoreAudio, part of OS X? Otherwise, there would be no need for drivers, and DP would not likely support any interface with a CoreAudio driver.

Soundflower can do a lot of this (for free). I haven't tried it with a wide range of applications, but it works, for example, with Quicktime screen captures.

Probably didn't word that all that well huh Bays. Sorry! What I should have detailed, was that apps like quicktime etc play seem to play straight out OSX. Like you said, DP uses driver and then talks to its interfaces. Yesterday whilst testing stuff, Quicktime was able to play straight into screencast software with no tweaks needing to get the audio into screencast. To get DP to play into screencast, I had to set Config Hardware in DP to the Screencasts audio capture driver to get it to work. And of course, that caused us to lose all of our DP audio bundle I/O such as outboard racks and our in's from other rigs, since the audio capture driver only sees one stereo pair. So the actual print, in the screencast software was missing all the outboard etc. I am sure there must be a solution, just dont know what it is !?!?!?!?!

I don't use any specialist screencast capture software, so I don't know the answer either. But I go back to Chris Breen's article on capturing both video and audio in QT using Soundflower. I haven't tried his approach with other applications, but its worth 2-3 minutes look at the article if you haven't already -- there are one or two steps in it that don't seem that obvious at first, but make sense when you think about it. I think the point might be that SF bridge system audio and other sources.

Thanks Bays! will check it out.

Sorry I can't give a real answer right now, labman. I'm way overwhelmed with "busy-ness," which has kept me pre-occupied since about November. I keep thinking it's going to settle down and I can get some things done, but that hasn't happened yet.

This is a subject that requires me to go into the software and take notes. I can't remember Screenflow well enough to comment sight-unseen.

That is quite alright my dear man. I too have been swamped since November with 'busy-ness'. It must be a virus.

ScreenFlow all the way. The audio routing is super easy. You can also record video from a webcam while recording the screen.

It is very good treating audio when editing video/narration - automated x fades and it help you find the right edit point in the narration.

Biggest issue is really it will not show the GUI of AU plug ins - yes, ScreenFlow actually can see all your AudioUnit plug ins.

Thanks for the details Basstrup. Appreciate the help.

How do we use all our cool 400 AU's without GUI?

Got Screenflow. Got tired of trying to make things work with the other screencast software. (Voila, iShowU)

Now just need to figure out how to get DP audio into it.

What audio interface are you using? Screenflow will show the audio interfaces in its audio menu, so you can choose one of those. It does seem like there was another step involved. It may be one that I solved in CueMix. A menu. I'll have to research that when I can. I do remember fretting over the same thing, but I must have figured it out. My earliest demos were made using a USB mic in the Mac, while playing DP through the desktop monitors, picking that up with the microphone. Then something changed, and I was able to do it directly through Screenflow, plus a microphone. The mic may be routed through my audio interface, though; I don't remember. But I THINK it's doing the Mac sounds and the USB mic, plus DP through the 896mk3.

Thanks for the input Shoosh. Using HD192 and 2408MK3 on that rig. (PCI) Screenflow does see the PCI-424 card. And I can select it as the source. But no audio is getting into Screenflow.

Labman, I've been looking at this, and I'm having a VERY hard time remembering what actually does the trick. But there are things I want you to take a look at, and see if they do anything toward the goal of getting audio through Screenflow.

• First, here's my setup for Screenflow Recording:

• 

Notice that on about the third and fourth track meter from the bottom of the 896mk3 section, there is a little gain showing on the meters. That's just so you'll know that it's actually receiving live audio from DP at this moment in time.

• Next, Look at Apple's AudioMIDI Setup and see if this menu option is enabled at the bottom of the Audio window:

• 

Only one of your audio interfaces can be designated this way. The sound icon and microphone icon will appear beside the device's name in AudioMIDI Setup. If you use that setting for your 2408k3, I think the device will play using the computer's audio controls, namely volume. This may or may not help facilitate audio getting into Screenflow.

I don't know what does the actual trick of hijacking audio into Screenflow. I've been looking at Audio-MIDI Setup, PCI Audio Setup, MOTU [USB] Audio Setup, CueMix, and Screenflow itself, but I can't figure out what the main factor is. I DID figure out that it's not working with my PCI boxes, but it does work with the 896mk3 Hybrid. The 896 is a USB device. Maybe it's more intertwined with OSX's audio system.

But none of that may be relevant. I vaguely seem to remember a driver you can install that grabs the audio from the 896mk3 and other boxes. Maybe that's the key. But I can't remember where I got it, if I got it. It's not on their website at Telestream. I'll keep looking.

To sum up what I can tell you today:

• • Screenflow actually grabs audio from my 896mk3 Hybrid.
  • I was also able to set up an output in DP through Soundflower (using the 2-track option) which Screenflow was able to recognize and bring into the audio mix. So, you could do a send from the Master Track (post-fader) through Soundflower 2-track, and that would provide Screenflow with audio.
  • While Screenflow sees my 1296 (PCI 424), it does not receive audio from it, and I cannot figure out a way to make it do so.
  • The solution may involve installing a driver. (found it) This driver apparently is installable from Screenflow itself. In the Preferences, under "Advanced," there is a line that says "Computer Audio," and on mine is says "Uninstall Driver." I can only presume that if the driver is uninstalled, the opposite is displayed, and you can "install driver." [forgive me for leaving well enough alone, and not trying to uninstall that freaking driver!]
  • 

Install the driver (assuming it works that way) and restart your computer or Screenflow, if necessary. Try your 2408mk3 for output, and see if Screenflow can pick it up. Use the Main Out channels (defaults set in MOTU Audio Setup). If it operates the way the 896mk3 does, you should be able to see it and hear it in Screenflow. If not, download Soundflower and use the 2-track option in DP to do a post-fader send from the master track. At least we know for certain that the Soundflower option works.

Excellent info Shoosie. Thank you. The audio capture driver was installed right away when I bought Screenflow.

Color me excited.

Created a Loopback device. It captured the DP audio with absolutely no changes needing done inside DP or to the DP engine. nothing at all. Yah! In screenflow, I selected the Loopback DP device, and voila... magic. I got audio. Geesh. Almost too easy. Before, I had been trying to make this complex Loopback device that had all our dozens of PCI I/O. Silly me, (Thanks again Stubbs for clueing us in on Loopback. It is brilliant with its options.)
