Help creating opening fan frame

[hobbybob]

Agreed, it was just to show there are more solutions, but you definately have a point there.
Didn't think about it that way. I am still learning everyday !

I had a play with Showtime and created a frame with a single dot then created several pan effects that moved the dot from its original position across to the right by 12 degrees at a time.
Do it 15 times and I think this is what you were trying to achieve.

hI Soforene,

I hope you can explain me how to do this coming Saturday ?

You can download this frame file and dissect it yourself (Check out the effects window).

Merely create one dot at the start position.
Run an effect to move that dot ending 12 degrees to the right.
On the second track display the original frame and run an effect to move that dot 24 degrees to the right (in the same time).
Repeat 16 times (Showtime Pro has up to 32 tracks) and when you run the show, all dots start at the same point but move out to create a fan, each point ending up at the finish point at the same time.
Voila! A sideways expanding fan.

Looking at Dimitri's video, you can easily do this in LivePro with a Key Effect.

Create a fan of beams in LD2000, I usually use around 400 points in that frame.

Open that frame as a cue in LivePro and on that cue make a Window Key Effect. So right click the frame and select New>Key Effect. In the Key Effect editor, go to the actions menu and select Window X. You can now use the slider to create a 'write in' effect from the left, right, middle or anywhere you want, this creates a much smaller filesize than a string of frames in an animation...

Cheers

But wouldn't each "tine" of the fan just appear in position one by one?
What Norty was trying to achieve was a flowing fan that opened out (from the side) not have a fan appearing one line at a time.

Ah ok, so zooming up as it sweeps...

You could use two lines in a key effect. One for position and one for zoom. Start position at left and end in the middle, with size at zero at the beginning of the timeline and full at the end... Not tried that method, but I do something similar where fans sweep in and out at different positions to the beat...

Thanks guys, will try to dissect the files and take a look at it.For now i am a bit flustered by all the options the program has.

Know this is pretty obvious but as newbs sometimes read these boards just thought I'd add a quick warning note, and that is I'd be careful using anything propagating out from a single point where all points are visible at time 0 or near time 0 as potentially you have 16 points overlaid which makes for a very hot beam.

No problem overhead, but be wary of an audience scan with so many beams laid onto a single point.

One way around this (although getting the accuracy in QS might be difficult depending on how fast the fan propagates) might be to key visible points so that each point only becomes visible once its actually moved from its original start position. ie. at the start only 1 point is visible even though 16 exist. As the 2nd point moves off the start position a 2nd point is keyed visible, as the 3rd moves off the start co-ordinates a 3rd point is keyed visible. Thus at the start point only 1 point is ever visible but away from that co-ordinate the points are visible as they spread out. Doing this would also avoid the start point appearing "hot" and thus brighter than the other parts of the fan. However, whether or not there's the keying resolution to do this in QS I don't know as I've not tried it. If doing it as 16 separate tracks, there is greater scope for accurate alignment in keying the visible points as you can do it with two keys on each track. You could also try starting each track at the original co-ordinates + 1 so that as each track starts over time it starts off the original co-ordinate, in fact that might be simpler and easier than keying visible points.

I haven't looked at your file as I don't have time but another way (which might be what you've done) is using a start delay on each track in which case you'll probably only ever have 2 points overlaid anyway (as each point has moved away from the point of origin by the time the next part of the "cue" starts).

Another way to make it audience scanning safer if it was intended for in audience use would be to start with the points laid side by side to create a small 16 point wide fan. Not quite the single beam point of origin but it should be possible to get a fan no more than a couple of centimetres wide and this should avoid any single hot point.

However, as I haven't tried any of these methods they are just suggestions and I don't accept any liability for their use in an audience scanning situation. The responsibility to check safety lies with the operator making pre show checks with such means as are necessary.
