Hi there, I’m a Newbie from a graphics background rather than a programming one so this is all new to me.
I’ve been using vvvv for a month now and thanks to the great tutorials
and searchable forums I’ve managed to understand enough to put together a patch that I’d like to use at a party.
So first off thanks very much for a great tool and thanks to all the people that help and
Currently the basics work so I thought I’d share it but it would be great if people could offer me any tips on how to optimise it and fix the frame rate issues I’m having.
What it does
A square grid of 16 Image Sequences will be projected on a wall for all the guests to see.
Just behind this wall is a laptop with a live webcam
The guests will press a big button and stand in front of the webcam (I’m using Space bar now)
It records a 3 second clip
This clip is then added to the grid being projected
This continues so that the grid is ever changing and everyone at the party can enjoy :)
How it works
-The User has only one input, pressing the Space Bar (although I’m thinking one big USB button might be cool)
- Then there’s a count down to get ready and then they record a clip of 3 seconds (no sound)
-This is written as Images to 2 Folders
ImageSequences: In here are 16 folders, each folder corresponds to one of the sections of
the grid. As new image sequences are recorded they replace the existing ones.
Grid: This folder is written to simultaneously and so backs up each and every image sequence
(I tried using the VLC plugin and writing to video but this was way to slow and just jammed
my system, images work better.)
Problems/ What I’d like to test
1- I’m going to use just one laptop. I don’t have a projector or another monitor yet so it would be cool if someone could test this:
ie on One monitor the Webcam Renderer is Fullscreened and on the other the Image grid is Fullscreened
2- Framerates: the 3 second count down seems to be right but then as soon as it starts recording/writing images it seems like it’s recording longer than 3 seconds.
3- Playback frame rate: My Webcam is 25fps but the playback always seems off.
4- Should I buy another USB Webcam or would this make things slower? It doesn’t have to be the best quality or anything, it’s just for a party, a bit of fun.
Any help and input greatly appreciated
