Hello all,
I am trying to create an image stream of a roman candle being lit and shot off for a lightsaber scene which hits some objects. What programs do you use? Effectslab? (i have only effectslab) If there are any others, please list them with the name, website, and whether it's free or not, and if it costs something, please list the price... although i hope it's not too expensive... unsure
Thank you!!!
and Happy Fourth of July!! (it just turned 12:00 midnight)

and don't ask why im up so late i just am sleep

Why do you need it to be an image stream? Can't you just use the footage?

You can create the image stream in EffectsLab; just import the footage and adjust the render settings to export it as still images.

wait,
so when I export it, will it have an alpha channel (when I click on "retain alpha channel") because I want to layer it on top of the lightsaber?

Thanks for the quick post biggrin ,

Ah,I think you are confusing image streams with alpha channels. An image stream is just a sequentially numbered sequence of images, which when compiled in order will create a video clip.

An alpha channel is a channel separate from the RGB channels of an image or video clip, which contains transparency data for the image or for each frame of the clip. It sounds like what you want to know is how to create an alpha channel of your roman candle effect. It actuality, you shouldn't need one in that instance, the effect should be filmed in front of a black background, and the Add or Screen composite mode can be used to remove the black at the click of a button. It will also blend the effect more realistically into the scene.

If you want to create an alpha channel though, you have to find a way to select everything in each frame other than your effect, and remove it. The only way to do that in EffectsLab would be through the use of masks, but the results are going to be mediocre at best, I suspect. You could also export the frames (or a Filmstrip, if you have Premiere or AE) and create the alpha channels in Photoshop.

Aha! I get it now! I think I'll just use the add button technique. Alpha channels are too complicated for me i guess... smile And besides, If i had after effects I wouldn't need fxhome... but adobe is just waaaay too complicated neutral

But Thank you sooooooo much axeman and good luck with your fxperience (i see you have a lot)
