Re: FLASH: Flash Flashing technique ?

[Flash Gordon]

I seem to remember from my university days (I have a degreee in Film/Video

and I work on computers... go figure)

That 24fps - the speed that motion pictures run - was decided upon because

it showed continuous motion smoothly enough to be perceived as smooth and

crisp motion (or something like that).

That being said I did some testing (i've used the technique before as

well)...

24fps seems to be the minimum frame rate you should use. I've set it as hih

as 60fps, and it's still recognizable (if the images are distinctive..).

You don't have to have a blank frame in between the images. The human eye is

pretty sharp at noticing motion.

Here's a 3 frame example (3 pictures)


at 60fps:

at 40fps:

at 24fps:

at 18fps:

If I remember correctly Baltazer ran at 30fps...


For smaller file size, it's going to take optimizing the images as much as

you can. It looked like Balthazer compressed the images a lot and it still

looked ok....


I hope that was clear...

Subject: FLASH: Flash Flashing technique ?



I was visiting a site by 2Advanced, and noticed a lot of similarities

between their work and that famous one... what's its name  Balthazar or

something out of San Fran [ can't find it in my URL's right now]


Anyway, what I noticed is that it has that quick flashing images

technique often used in commercials to give it that hi energy feel. Yet

the fla file sizes are quite small [ under 300k],.


I am wondering about 2 things:

what are the techniques used to make those flashing images... is it using

an image in a single frame, blanking the next frame and then putting the

image in again at a different location /size for another single frame?

and then flashing off?   Is that long enough for eye recognition?


The motions are fast and continuous.  It seems unnatural to the way flash

works to create them frame by frame... no tweens, e.g.   So, I am

wondering if other programs are used to establish that technique or how

they are done in flash generally.


The second thing is: how do they keep the files so small when they

apparently have a lot of images and different images loaded into the file

that flash for only a second or so...
