Hey guys

for my movie i plan to shoot on a very low budget, it's a sci fi action adventure movie, i am looking to buy visionlab. For my low budget i plan on using water pistols as guns, i have been in some toy shops and seen water pistols that look just as real as a real gun. You know when you fire a real gun, the sliding top of the gun pulls back to eject an empty shell then when it goes back forwards it pull another bullet shell from the magazine, and that is known as semi-automatic, well as these water pistols don't do that, i thought if i can create this effect in visionlab then that would be awesome, is this possible, to actually have a shell created that flys out of the ejection chamber and recoil effect as i described?

any help much appreciated

Well for the gun top sliding back it would be near impossible without having the prop do that by default. On the other hand the shell ejection would be much , much easier. You could use a stock footage clip of shell ejection from Detonation films

Only the winchester ones are free by the way. Or you could find a clean image of a shell and key it in easily and animate it to spin and fall, which if you are firing a lot of rounds would be time consuming. I hope this helps!

i saw a tutorial a long time ago on some site which showed you how to make a plastic guns top slide back and forward, it was not too hard to leanr but you needed loads of different softwares and i hoped that one software like visionlab could do it.

Well you could take a back plate of the shot you are going to have it shoot in and then combine the two and manually make it slide back in forth if its in plain view.

I'm not sure what the best way to achieve this in VisionLab would be, but yes you are correct that it is possible. I have also seen the tutorial for it you mentioned, but I don't know where it is. Essentially though, it can be done fairly easily in After Effects.

All you do is cut the top of the gun, and animate it back for a single frame or whatever with motion blur, and you just paint in the backround where it was before... Because it's only 1 frame, it's very easy. Can someone translate this into Vision Lab? If so, I think that's what he wants.

Yep, with some masking and motion blur you could do it.

With the right camera angles though, and some nice muzzle flashes added in, you might never see whether it was sliding or not.

You could buy a Electric kickback airsoft pistol. You can get them online for $20 or less. The slide moves everytime you fire and looks pretty real.
