This new vog is a minor departure from the recent ones that I’ve been making, which have all involved zooming and draggable movies. I’ll return to those shortly. The Lugano train vog is a larger work, and is deliberately intended to be more polished than the everyday variety vogs. It has been embedded so that it plays within QuickTime player, primarily because it is 720 x 540 pixels in size and that just looks silly as an embedded movie in the vog.
There is a picture track that takes up all this space, which is made up of three jpegs. The jpegs are photos that relate to the trip to Lugano I had earlier this year (for the EdMedia conference). Embedded within this is the video track, which is the footage that I shot while travelling by train from Zurich to Lugano on one foggy, damp, afternoon. Mousing in to the video track progressively slows the video, to half, quarter, eighth normal speed. Clicking within the video restores the track to normal speed.
One child movie soundtrack loops, this is an announcement made during the train trip about which stations are coming up next, in German and Italian. This is only a short sound grab, and so this loops via the child movie track independently of the duration and play back speed of the parent movie.
I added a small sprite track that contains some hand written frame rates. This is to let the user know the effect of mousing in to the movie and indicates feedback as to what the behaviour is. Hopefully if the soundtrack is looping at this point they might also wonder how a movie can slow down the video rate but not affect the soundtrack. They’re hand written because I just wanted something like my notebook going on, nothing fancy, nothing with that fancy Flash come vector aesthetic. There’s nothing fancy with the scripting either. I could have written a script that retrieves the frame rate and presented that in a text track, but that just adds to the processor overheads. The way I’ve done it is to just attach it to the same sprite that counts mouse enters, and when it halves the frame rate it also just changes the image index for the second sprite.
Since the movie is targeting QuickTime Player I added a couple of buttons so that clicking one moves the movie into full screen mode, clicking the other moves the movie back to normal. After experimenting with this I changed the event to mouse in rather than mouse click, I much prefer the action of ‘caressing’ the surface of the object that the mouse in event produces, rather than the lugubrious ‘click here’ that makes us all into experimental subjects. Touch with the mouse, things happen.
There are three photo’s in the movie as well, revealed simply by mousing around in there. Finding and displaying a photo has the effect of loading another child movie soundtrack, though I expect over a network this will not work because of the lag – mousing out stops the childmovie track and I don’t think it will have time to start playing given network lag. If this is the case I’ll rescript this a bit more so that mousing into and revealing a photo will play that soundtrack until you click. In fact, that’s a better idea, so I’ll do it now (insert sound of coding…….)
Ok, that only took 5 minutes. So, now if you click the photo then it stops that soundtrack and returns you to the other one. The three sound tracks I have added are rambling affairs, but suited to the medium. One is just remembering the train trip, one is thinking about thinking about place, and the other discusses my vog practice. This movie works much better if you take the download option…
