Howdy folks: When I first read the PhotoMorph2 manual I was intrigued by the mention on p156 of "moving alpha channels". I have been busy since have fun fun fun with all of PM2 features. Now I am on the lookout for more and after having to make a mask for the frog to BeamUp as posted here by Ed, I have been thinking of moving the channel. One could make a whole family of wipes or faders using PM2 Transitions, I guess. But what else are moving alphas good for? Lets hear from you all on what YOU use flying masks for. How do you make them? Look forward to having your input … Cheers … John

>>Lets hear from you all on what YOU use flying masks for. I make music videos…. Let me explain, I just finished doing a piece for some promotional stuff we're doing. In a former life, I was a rock musician. So I took one of my old songs and made a music video for it using nothing but still images and PhotoMorph 2. The intro features an unique use of alpha channels: First I constructed an AVI that featured a constant stream of Morphs on varous objects. This was saved as its own AVI. Next, I wanted the screen to start 'black', then have a skinny area revealed, sliding down from the top. I constrcted an image that looks like: +——–XXX——-+ | XXX | | XXX | | XXX | +——–XXX——-+ I used a white start image and this as end, transition, slide down. Next CLIP: I wanted the shape of the Bar to be "shaken" for 5 frames. I used one of the new Stylize effects: Reflection, however, any distortion would have worked. I had the effect move in and out over those 5 frames. This would be in time with the music. Filter 2 featured a Zoom In distortion from 0-20% Thus, as the bar shakes, it would get slightly bigger. Next clip… I held the bar 'bigger' at 20% for a number of frames to keep time with the music. Next clip, I repeated above, increasing the zoom size every time. Thus, with every strong beat of the song the mask gets bigger. I rendered that as an AVI file. Finally, I used the distored bar AVI as a mask. The start image was the Morph sequence I previously created, and the end was black. The final result, had the morphs going on inside the bar. More of the morphs being revealed with each beat of the song. The finished effect is very cool. Look for "Society of Sponges" on a promotional CD-ROM coming soon…. Unfortunately, I can't make it public 🙁 I will try to include the .PMP files and *maybe* a tutorial on the Promotional CD so that all PM2 users can benefit (and we can pay the bills 🙂 Actually I use Alpha Channels for almost everything. That's just one of many things I've done. Anyone else? -Ed

Ed: >>I was a rock musician. So I took one of my old songs and made a music >>video for it using nothing but still images and PhotoMorph 2. WOW. Well from the description you sure know how to make PM2 rock <BG>. >>effect move … 5 frames. This would be in time with the music. Now I knew that v2.02 had WAV file support, I just knew it! I was most inspired by your detailed description of your video making with PM2. I have a long way to go, but at least I now know where the mountain is. I have uploaded FLASH.ZIP which is my humble first effort using a moving alpha channel with PM2. It is simple, no music 8-), but effective. This stuff could get addictive. Cheers … John

Woah…… PhotoMorph 2.02 DOES NOT have support for .WAV files. It would be nice, but no. I kept the music "in time" by figuring out the number of frames needed through trial and error. I could have used some of the more advanced features of Adobe Premere but that would have been "cheating". I used Adobe Premere only to string the 6 or so AVI files together to make one large AVI and to add the music. -Ed

I just downloaded the "moving Alpha Channels" example that you posted. It is excellent! I encorage anyone who has PM2 to take a look at your project. -Ed

Ed: >>I encorage anyone who has PM2 to take a look at your project. Glad you enjoyed the FLASH.ZIP. This is a real compliment coming from you the expert. And I saw your picture in "Amazing PhotoMorph News" which reached my snowbank here in Canada yesterday. Is that a morph or are you really that goodlooking? <VBG>. Best wishes … John PS I ordered Stylalize today: looks neato

Hi John, No that picture was not "morphed" I really am that handsome (VVVBG)! I answered the phone when you called to order the stylize pack, but then I handed it to someone else before I knew it was you. After the order was taken and I saw who it was, I had wished that I had gotten a chance to chat. -Ed
