Hi Ian can you clarify - I've not read too deep on this: On 12/06/07, Ian Wood [EMAIL PROTECTED] wrote: Core Image Fun House lets you use *Core Image* filters - nothing to do with QuickTime, and strictly OS X 10.4 and above.

Yes then we could all make apps like this: http://www.stone.com/iMaginator/Quick_Start.html That is are not Core Image filters and transitions both available to QuickTime. From Trevors EQT documentation: command qtAddFilter MovieControllerID, EffectType, StartTime, EndTime Description: Adds a filter to the specified time of a movie. ... EffectType: Type to add (blur, sharpen, edgedetect, emboss, convolve, alphagain, rgbcolorbalance, hslcolorbalance, colorsync, filmnoise, solarize, colortint, lensflare) From playing with Quartz Composer my impression has been the Image Units used in Core Image can be used in QuickTime - OK so only on tiger and above on OSX - but still... Some References And this from : http://www.apple.com/macosx/features/coreimage/ And Core Video allows developers to apply all the benefits of Core Image to video — blazingly-fast performance of filters and effects, per-pixel accuracy and hardware scalability. Tiger includes the following Image Units: Blur - Median Blur - Gaussian Blur - Motion Blur - Zoom Blur - Noise Reduction Color Adjustment Filters - Color Controls - Color Matrix - Exposure Adjust - Gamma Adjust - Hue Adjust - White Point Adjust - Color Cube Color Filters - Color Map - Color Invert - Color Monochrome - Color Posterize - False Color - Sepia Tone - Mask to Alpha Compositing Filters - Addition - Maximum - Minimum - Multiply - Source Atop - Source In - Source Out - Source Over Gradient Filters - Gaussian Gradient - Linear Gradient - Radial Gradient Sharpen Filters - Sharpen Luminance - Unsharp Mask Distortion Filters - Pinch Distortion - Hole Distortion - Bump Distortion - Displacement Distortion - Glass Distortion - Glass Lozenge - Torus Lens Distortion - Twirl Distortion - Vortex Distortion - Circle Splash Distortion - Circular Wrap Distortion Generator Filters - Checkerboard - Constant Color - Lenticular Halo - Star Shine - Stripes - Sunbeams - Random Generator Color Blend Mode - Color Dodge Blend Mode - Color Burn Blend Mode - Darken Blend Mode - Difference Blend Mode - Exclusion Blend Mode - Hard Light Blend Mode - Hue Blend Mode - Lighten Blend Mode - Luminosity Blend Mode - Multiply Blend Mode - Overlay Blend Mode - Saturation Blend Mode - Screen Blend Mode - Soft Light Blend Mode - Color Blend Mode Geometry Filters - Affine Transform - Crop - Perspective Transform - Lanczos Scale Transform Halftone Filters - CMYK Halftone - Circular Screen - Dot Screen - Hatched Screen - Line Screen Stylish Filters - Blend with Mask - Edge Work - Height Field from Mask - Pointillize - Shaded Material - Bloom - Edges - Gloom - Pixellate - Spot Light - Crystallize Tile Filters - Affine Clamp - Affine Tile - Op Tile - Parallelogram Tile - Perspective Tile - Triangle Tile - Kaleidoscope Transition Filters - Page Curl - Copy Machine - Dissolve - Flash - Mod - Ripple - Swipe - Disintegrate with Mask Also this from : http://developer.apple.com/macosx/coreimage.html Not Just for Still Images Core Video, joining Core Image in Mac OS X Tiger, delivers a modern foundation for video services, providing a bridge between QuickTime and the Quartz Core framework for hardware-accelerated video processing. In the same way that you can insert filters into the rendering pipeline for images, you can insert filters into the video display pipeline. Like Core Image, a Core Video pipeline reduces CPU load and increases performance for other operations. And Core Video allows developers to apply all the benefits of Core Image to video—blazingly fast performance of filters and effects, per-pixel accuracy and hardware scalability. ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

On 12 Jun 2007, at 14:38, David Bovill wrote: Hi Ian can you clarify - I've not read too deep on this: I'll have a go. ;-) QuickTime has a set of built-in transitions (*and* a set of built-in filters), going back many years (QT3?). These transitions and filters are available to any app using the QT APIs, and the filters can be seen when exporting movies from QT Pro, exactly the same as the ones in Trevor's external. All of these use the CPU, and the transitions can be pretty rough with large areas and slower CPUs. Core Image is a totally separate API that leverages the graphics card processor, but QT (in Tiger and above) is able to *play* them. They still aren't QT effects, though. Basically there are two separate sets of filters and transitions available to Tiger, which cover quite a bit of the same ground.

Re: Ken Burns (was Re: Ripple)
OK - so my question is can Trevors existing external apply Core Image Units to QuickTime files so that QuickTime can take advantage of them using Core video? If not how hard would it be to add, because then we could take advantage of the hardware accelerated effect on still images via the Player object? ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Recently, David Bovill wrote: One of the aims is to do a Ken Burns type effect i a slide show. The problem is getting the transitions fast enough and yet smooth enough. A worthy goal, though I doubt Rev will ever be able to do this natively for images of any size. It's simply too slow to update when displaying movement of images that change in size and/or transparency. Perhaps QuickTime will lead to a solution via the effects others mentioned, or using Trevor's EQT external.

Re: Ken Burns (was Re: Ripple)
True - still I think for some applications a very slow, or slowish, subtle movement will work fine to add attention to an image - it just must be very smooth? ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

It cannot. It only adds the built-in QT effects mentioned in the docs.

I'm not aware of any APIs in QuickTime that work with Core Image. The stuff you export from Quartz Composer uses Core Image I believe and that plays back in QT but I think that is a special track as opposed to individual filters in QT. -- Trevor DeVore Blue Mango Learning Systems www.bluemangolearning.com-www.screensteps.com [EMAIL PROTECTED] ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Re: Ken Burns (was Re: Ripple)
David, If you want something nice and very fast, try a ken burns slide show just use iphoto and dump it out as a quicktime movie. The joke with my video producer is how amazingly well iphoto does just guessing on pan and scans. its a bit creepy, kind of like those segues that itunes does on shuffle all the time. it takes a bit of time to do the pan and scans in final cut (we do them for exhibits) and i photo does them with three or four mouse clicks! We often give iphoto a shot first as its sometimes good enough if we are in a real hurry and doing the job as an extra. we get raves from the clients and have to embarrassingly admit it was not our genius... My video producer comes fro amazed m a large format still background so is very picky about how stills are used and i was when i first talked to her about what iphoto does and she sheepishly admitted that she had done a couple of slide shows for family that she didn't have the time to do herself and was amazed at the quality she got out. I use it all the time at our japanese model train display and it always seems to get the direction the train is moving and do the pan in that direction and not perpendicular to it. and it usually zooms in and and out on the front of the train... cheers, Jeffrey Reynolds On Jun 12, 2007, at 11:34 AM, [EMAIL PROTECTED] wrote: Along these lines - I'm doing some image experiments.
