Is there a program that does REAL TIME camera switching?
I have Vanilla Baby, but it only works 320X240 which has real time switching for 2 cameras (although I haven't figured out how to match the audio yet). But I was looking for a program that does it in real time (I know that Vasst Ultimate does it during playback) so I can have a two camera shoot with my laptop and real-time camera switch while recording. I think :"Wirecast" by VARA can do it and I think the resolution is 640X480, but I haven't use it so I can't be sure.
Any suggestions? |
Depending on how many sources you want to switch, Newtek offers a couple of different options. The "Tricaster" is one of them and the "VT[4]" is their flagship - you can edit, switch between multiple cameras (up to 24), do real time graphics, animations, editing, and lots of other cool stuff. It may be a bit pricey for what you're looking for, but often times you can find older used systems for much cheaper. The resolution is 720 x 480. http://www.newtek.com

Thanks. I was aware of the hardware solution to the challenge, but I was hoping for a software solution to the real-time camera switching. I have been reading some more info on Varasoft's WireCast and it seems to be able to do this, but I think it is mainly for webcasting, not actual full screen DV work. So I am still looking.

The biggest problem you have is the number of inputs you can have without doing some sort of hardware interface / upgrade. You will need the necessary inputs to be able to handle incoming sources. Some programs will use an existing firewire interface, but it all depends on how your cameras output that information. If you find something, I too would be interested to know if there is a way to live switch a couple of cameras.

I figured I would try it with my laptop with my PCMI card has two firewires. From what I have read on the Varasoft site, it should work that way. I know that Vanilla Baby recognized both a High8 and a mini DV camera on its interface and thus I was able to do camera switching with that program. I have yet to try it with WireCast.

i dont trust real time switching software from a pc... for live events anyway.
one hiccup from the VT4 was all it took to scare me away from it. |

Live switching can be a real problem and it can start with the camera interface. The 1394 interface can be a few frames behind Live, then the switcher adds a frame or two. Put the feed from the switcher up on screens beside a stage and it can all get pretty horrid.
The only two interfaces that seem to have small enough delays to be workable are the analogue ones, composite, S-Video and component. On the digital side SDI meets the need. For webacasting this isn't an issue, for broadcasting not so much of an issue but you need to be careful where the vision gets fed to, for screens at live events at least. We still hang onto several MX50s for this reason. |

i think that was just a sample.
the fact is that running a computer involve more complex parts than running an hardware switcher. Statistically, you have more chance to freeze PC, get a blue screen or a simple bug from a PC running a mix of software and hardware than a mixer/switcher. if you are ready to face a slow reboot of a PC during a live session , i see no problem. Personally i use a videonics MX-1 that has 4 composite/YC inputs and worked like a charm for several years. I experienced only one time a crash and it took only 3 secondes to switch off/on the device. |
^thank you!
Kit, where do you get such great faith in pc's?! I was using a turnkey VT-4 PC system created for nothing but the VT4. VT-4 is a really good program that can do everything; editing, switching, graphics... all in an interface that I enjoyed. So I did like it. But for live events, there was no way we were going to stick with it when our current video switching hardware almost never fails. Even if Sony Vegas froze, it's an editing program and not made for live switching so it's okay to have hiccups during post-production... it's not LIVE. But I would never recommend a system like VT-4 for live switching if it freezes more than rarely. So calm down Kit. Maybe you enjoy living on the edge but I and most other people need assurance my live switching hardware doesn't fail. |

Remember that even though it won't run windows, your MX-4 still runs hardware and software just like a computer. Yes, it's faster, but the capabilities are more limited. I guess it's a fair trade-off for the time being. Quote:
