Hey everybody. I have downloaded the trial version of PD9 ultra, and I think its going to be perfect for my needs. I will purchase the full version this coming weekend.

Question though..I am going to be recording music lessons for my students.

Is it possible to record from 2 camera's directly, via Firewire ports? I have 2 firewire ports, but not a 2nd cam at the moment to test. This would make the 2 tracks completely in sync, if this method is allowed.

Hi Matt

Welcome to the forum!

You can import two separate videos - but not both at the same time.
Happing editing

Would it work if you had a firewire splitter or hub, have your two cameras connected to the splitter/hub then one connection to the computer

Hi

I'm not sure, I use cameras with hard drives and memory cards.

All you can do is try Happing editing

I am assuming that she has her comp in the same area and wants to record to PD9 "LIVE"

Hi Matt,

PD9 really isn’t intended as a live multi-camera mixer, like for a live broadcast for instance.
But to do multi camera edit of your lessons, perhaps you might try this…

Let’s say you’re presenting a guitar lesson. Camera one is the long shot of you in the chair with the guitar. Camera two is a tight shot of the neck/fret board for a close-up of the fingering.
Start both cameras, and prepare to start the lesson by doing a countdown by saying… 3 – 2 – 1, and then proceed with your lesson.

Once your lesson is complete, import the footage from the cameras to PD9.
Place camera one’s footage in track #1, and camera two’s footage in track #2.
Then Align the 2 tracks, so that when you hear your countdown in both tracks, they are in perfect sync.
Now listen to each track’s audio and determine which of the two has the quality you like the best, and then mute or remove/delete the inferior audio. Now you have a master audio that will service both tracks/footage.

Now you can start to edit out unwanted bits, and continue editing so it appears that you are in effect switching back and forth between cameras 1 and 2, to display which camera view you want to show on the screen at any given moment. Or place the footage from both cameras in a Split Screen to show both views at the same time. Or place either the footage shot by camera 1 or 2, in the bottom right of the screen as a small inset screen. Or place this small screen so it appears to be behind you over your shoulder.

The options you have in PD9 to edit and display your lesson shot with two cameras, is virtually limitless. You just need to create a visual or audio reference point at the beginning of your lesson, so that in the editing stage, you can align the tracks to be in sync.

If you want to throw some money at the problem then something like Tricaster (Google or look on eBay.com in USA)
which is a true multi-camera input mixing and switching desk.

or this
http://cgi.ebay.com/VIDEONICS-MX-1-VIDEO-MIXER-TITLE-MAKER-EDIT-SUITE-/220740514497?pt=LH_DefaultDomain_0&hash=item336528f2c1
As stated in previous post, PD can record off a single source but that source can be whatever video source depending on the input card to the PC. I dont know what you would need to convert RGB and sync to be Firewire or if you would need a pci video card with RGB inputs.

Search Google for multi-camera mixing desk and you will find others Search eBay for Video Switchers and routers which seem to run around $100-$500 or more

See also http://en.wikipedia.org/wiki/Vision_mixer and maybe look for Tandy or other home consumer electronics as opposed to professional gear.

I presume I wont be deleted by Dafydd since this is a hardware adjunct to any video editing software and so non-competing with Cyberlink - hopefully

Do it yourself with this easy DIY circuit

http://www.glolab.com/freeinfo/images/videosw.pdf

or contact your local Amateur Radio and SlowScan TV folks to have it built for you for a few bob. Its essentially the switch without pan fade etc which you can still do in post-production with PD

Cute logic, uses a MAX454 Video Amplifier chip See also EL332 logic ccts on Google The pdf above does not do the Sync Stripper and DC Restore but the circuit transmits 200MHz (-3dB bandwidth) video signals while stripping off the sync pulse and performing DC restoration. It is configured for a typical video cable driver application driving a double-terminated 75Ω load

If you dont have sync resolution what you get is basically electronic crash switching and possibly a frame or two of missing sync resulting in frame roll or tearing. However if you then edit the crash out in post production at the video level and keep the sound, you should get an OK switchover. One way to test this without actually building the analogue switcher would be to connect a simple mechanical switch connecting two video inputs to one output and click the switch. At the recording input yould definitely get a frame sysc loss and then you could test how well PD can edit out the error and whether or not there is a click or crunch in the audio too.

In fact Maplin in the UK sell CCTV switcher boxes which 'crash' switch for $24 GBP

I dont know if this sort of switching would cause Vista to detect loss of DV input and halt recording. Would need to test this too.
