Interesting ideas. Obviously the high end expensive systems are designed to do just this but you are looking at 10's of thousands of dollars.
I'm always interested in coming up with low cost solutions to simulate high production value type of effects. SOOOO here are some suggestions
If you want to do this in real time, then you really have to look at a video mixer
. the type of effects that you want to do, ie 3d effects mean that you need to go with the latest equipment. Obviously the high end studio mixers have this with multiple effects units but at the reasonable level
(under 10 grand) the Panasonic Mx70 with the 3d card should be able to do this and you probably could rent one, you would have your sources could be live or pre recorded you then cue
up the transition effect
and then when you want you execute it. Since you are not looking for all the multiple screen
capabilities of break the image
down to multiple screens etc
you probably would find this solution practical
but not overly cheap.
It also is possible the the Newtek Tricaster systems might also be able to do this but again you are still looking at about 10 grand by the time you get the software/hardware and the pc to run it. http://www.newtek.com/tricaster/index.php
On the other hand
IF you could move away from the need for a live feed you might be able to use something like Sony Vegas Video, and have your effects and clips all worked out in advance
, and use the external monitor
facility to project it.
It is a little tricky trying to get it to work all on one system
, So what what I have done is to have two pc's running vegas and have each feed into a video mixer
I use a MX50 but you could use a MX30 which sell for about 700 dollars, you then have your original footage say of the rotating cube running on one system
and then on your other system
you would have the footage that takes your keyed or overlayed or inserted image
and have that cued up.
You take your original footage and have it playing with a loop set up on the time line
so that it keeps looping, you then have your effect
footage set up so that it begins at a position of the cube that you can match to (this is the hard part since one system
cannot really automatically trigger the other) and you then manually start the effects clip playing at the point
where the two images match (does not have to be exact) and at the same time. you use the mixer
to transition over to that feed.
If you only had one pc and no mixer
, it is Possible, but tricky to have all your footage on one time line
you then set up a loop for your original footage so it keeps looping and then when you want the transition, you have a pre rendered transition on the time line
right beginning after your end of the loop you then move your loop point
so that it now covers the transition effect
footage and it plays, and you then stop the playback at the end point
It is possible, takes a lot of concentration and playing around but you can get some great effects.
Vegas video sells to schools for under 300 dollars, you would need a decent pc in most cases you best system
is a firewire out to a camcorder and use the camcorder analog output to your display this keeps everything on your desktop off the video screen
and keeps your graphics card and the video out seperate.
I have done this when you want some wild title effects or introduction
clips to show on the projected screens during a live concert, and with concentration and coordination you can do some pretty advanced stuff
The advantage of Vegas is that it will allow you to import and match clips from just about anything. So we have used animations from Maya for instance along with video clips, power point etc
. We have used some of these techniques to simulate a big network
sports type broadcast for player stats etc
. As long as you don't need the feed to be live, it works well. If you need live input to the 3 d effects than you need an effects engine
with your mixer
, and you are pretty much back to the first two options
