Flash :: Create Videos With Transparency/alpha-channel
Sep 21, 2010What is the best way to create a video with an alpha channel, suitable for flex/flash? Does it need to be FLV, or can it be MP4/MOV as well?

ActionScript 2.0 :: Create The Proper Code That Will Control The Alpha Transparency Of A MC?
Mar 7, 2005how to create the proper Actionscript code that will control the Alpha Transparency of a MC I want as a preloader. I want the MC to start of at 100% alpha-transparency, and then decrease to 0% alpha-transparency when the whole Scene is loaded. Also, it should show the precentage of the Scene loaded. I have the code that I thought would work to control the alpha transparency of the mc and loading it. But, I get confused with the perloader code to incorporate into the alpha transparency code? Does this make sense; is it possible?In Leaman's Terms, As the scene loads, the mc goes from invisible to visible at completion of the scene load.
Here is the code:
Code:
onClipEvent (enterFrame) {
loading = _parent.getBytesLoaded();
total = _parent.getBytesTotal();
[code]....
Now, I have no idea if and where you'd include the poper code to control the mc's alpha transparency based on the percentage of the scene loaded? Can someome maybe rework the code to make this work. And use a working example, that way I see it working to fully understand the concept? The mc's instance name is "sm_logo". Where would I use the instance name in this code, or better yet the proper code alltogether?

ActionScript 3.0 :: Flash - Keep 'Alpha Channel' Data With PNGEncoder?
Jul 25, 2011I'm trying to import an image and assign it to a Loader object, which works just fine, though I want to use the PNGEncoder rather than a the JPGEncoder, because if the source image has an alpha channel (transparency) I want that data preserved. The code, or the encoder, or something is preventing or deleting the alpha channel data. What should be transparent is showing as white.

ActionScript 3.0 :: Flash Can PerlinNoise Control Alpha Channel?
Oct 17, 2011I'm trying to accomplish a similar effect as seen on :[URL].. I suspect its just perlin noise displacement with a loop on the DisplacementMapFilter to decrease/increase the distortion over time as well as an alpha tween. I have been able to spy that they are using caurina tweener, which isn't of interest to me.
Its the principle I'm after, not a copy of their effect. I'm trying to assign an alpha value to say, the White/Black area of a PerlinNoise generated Bitmap. Where the White would be 0% and the dark 100%. And have that White value increase over time so that the entire image, the filter is applied to, gradually fades into view.

View 1 RepliesVideo Encoding For Alpha Channel
Jan 20, 2010I am experimenting with video using the alpha channel capability of the FlashCS3. I followed the tutorial on the gotoandlearn website on how to create chroma keyed video. I exported an avi video file having removed the background. Ive used Flash video encoder for VP6 and flash player 8 with encode alpha channel ticked. However my swf is not showing the video, just a white blank where it should be. It puts out the audio only.
This is the log file.

IDE :: Alpha Channel And Mouse Events?
Nov 3, 2009I have some png images which were converted to movieclips and exported. I would like all clicks on the transparent parts of the png to be ignored by a movie clip on a closer layer and have a movie clip under the transparent parts receive the event. Is there a way to do this? When I convert the symbol to a movie clip, the authoring tool automatically puts a bounding box on it so all clicks in the bounding box are detected. I tried searching mouse events and alpha channel stuff on the forum.

View 4 RepliesAlpha Channel Deteriorates On Scaling Image?
Sep 24, 2009Using Flash CS4. I have some images with transparent backgrounds that I'm putting into Flash. Placed in Flash at original size, transparency looks great. However, when I scale the images to any different size, the edges of the alpha channel get real rough, not smooth and aligned to object. I've experimented with png, targa, gif, but all seem to have this problem. Is this some issue with Flash? I don't remember seeing this problem in say Powerpoint.

ActionScript 3.0 :: Alpha Transparency Not Working On PNGs?
Jun 17, 2011I'm currently constructing a scrollbar as part of a website using as3 and png images. I've got loaders for each image inside of an array, and when loading on each image finishes, it's added as a child to a sprite on the stage. I've got a background image with no transparency, which loads fine. On top of that, I've got the actual slider, which loads the RGB data, and appears to be using the alpha as a 1-bit mask. So anywhere that I have partial transparency, it just shows up as black, where it should be showing the background underneath. I can't find any attribute that will change the way loaded images process alpha transparency.
