Hey,
i am wondering about how to make a realistic muzzle flash. i see for automatic guns you have rate of fire, but it does not seem very realistic to have the flash appear on one frame then disappear the next without "fading"
it would be nice if was some slider like the rate of fire that allows you to determine how many frames the flash last. that would be faster then key framing them your self. Also What does a muzzle flash look like on a real gun? from these videos(one with artificial flashes, the muzzle flash seems to be exaggerated. Any one have any ideas?

A muzzle flash frequently lasts for 1/100 of a second or less, particularly for automatic weapons. The chances of a single flash being visible on two frames are slim.

Watch some action movies and look at the flashes frame-by-frame. Any big-budget movies are likely using blanks in the weapons, so you are seeing real muzzle flashes. You will generally find that they last a single frame, are not completely consistent in how often they appear, and that the brightness of the flash depends on the relative brightness of the surroundings.

You start by saying that x doesn't seem realistic, and follow that up by asking what a real flash looks like. Sounds kinda like you skipped the critical step of research. You'll need to get a clear idea of what the real thing looks like before you can really determine what looks realistic or not. Keep in mind, as well, that as with many things on film, muzzle flashes are typically exagerrated for effect. They use blanks that are specifically designed to create big flashes, as real flashes from live rounds are often much less impressive, if visible at all.

Look you didn't answer the question Axeman. You defended the limits of the software, unless you can do it. The issue is how do we do what he's asking. Because I'm asking the same thing. I was in the military and in the military muzzle flashes DO NOT EXIST, because we have muzzle suppressors. Either way. Whatever reality is, thats cool. I'm with you.

But does anyone know how to automate flashes every other frame? On off and then on off again. I'd appreciate it. I will continue looking, I'm just starting with this, but if anyone knows please share.

Thanks in advance.

The OP was asking about muzzle flashes fading in and out, instead of just being on/off/on/off - For the most part, making a flash fade in or out will make it too long, and it won't look convincing. There are of course exceptions, particularly with shotguns, but what I was explaining in my previous post is that muzzle flashes, in general, happen too quickly to exist on more than one frame. If you really want the flashes to fade, turn the Intensity way down on the frame immediately after the main flash, to make it fade out. There's no limitation of the software that will stop you from doing so, its just typically not going to make the most convincing flashes.

As far as your question, Set the rate of fire to 100, and then use the On/Off switch(under Render, in the Effects Attributes) for the flash to turn it on and off every other frame, or whenever you want the flashes to appear.

Axeman thanks for the quick reply. Just to clarify that I understand this. You're saying that I set the rate of fire at 100, then manually go in every other frame and delete?

There is a toggle switch, green for effect on, or red when it is turned off. Just go through manually switching between red (off) and green (on) to give the desired effect over as many frames as you like.

Yeah, what Mike Q said. If you want to have complete control over exactly which frames the flash appears on, then you just use that toggle to turn it on and off whenever you want.
