Yes, not as good a value as XnView! I love the new crossfade effect. I'd just like to combine it with the pan/zoom type effect. I don't know what the other post was talking about as far as a "Zoom" effect - I don't see one. (EDIT: Oh, they were talking about the other freeware screensaver, duh!)

The Ken Burns effect does add something - it holds the interest better. We do slide shows for a club for teenagers, and noticed that when someone with a Macintosh did a slide show with that effect, it seemed to hold their interest better.

Another program that illustrates this effect is MotionPicture, available at:

http://www.cs.ucr.edu/~gstitt/motionpicture/

I tried it, and I think it's very cool! I highly recommend people check it out.

Mac OS X and Windows Vista are already using this effect in their viewers, so it's getting to be more and more common. (But I don't have Vista!)

MotionPicture creates the effects by creating combined pan/zooms, but these combinations are basically random. By contrast, I've also recently tried the program Zoom Studio. It's not a slide show viewer, but it animates individual images using Ken Burns effects. The difference is that Zoom Studio allows you to control the effects in a precise way. It's available at:

http://www.inzomia.com/

Until I saw these programs, I'd assumed these kinds of effects weren't even possible in real time (not smoothly, at least). I would love it if XnView could implement these kinds of effects.

I note that MotionPicture requires a geForce or better graphics card. This suggests to me that it's sparing the CPU by shifting the load of the graphics operations to the graphics card, explaining the smoothness of the effects. (They look great even on my 733 MHz machine.)

What I'd really like to see in an image viewer is the ability to control some of these effects with the mouse or keyboard.

For example (ignoring existing key assignments for a moment) CTRL-<right> might tell the program to start a pan to the right. Then the image would slowly start panning smoothly to the right. The speed of the pan could be set by the user.

Smooth zooms could be controlled in a similar way.

With some thought, one could find ways to implement simple commands to initiate pan movements at user-controlled angles(not just left, right, up and down), and smooth zooms to user-set endpoints. For example (again, ignoring keyboard assignments), if an image is already panning to the right, pressing down arrow could cause the image to start panning down and to the right. The more you press the down arrow, the more severe the downward angle. Or you might achieve the same kind of effect with mouse commands.

Ideally, it would be cool to be able to save these controlled pans and zooms with the image so that they could be incorporated into slideshows. For example, you might press "record", perform pans/zooms, then press stop, and be able to save these operations with the slideshow. Sounds ambitious, but ZoomStudio already does this with individual images, so it is doable. Also, it would take things a step beyond what's apparently already available in Windows Vista and Apple OS X.

I just found out by coincidence about the Ken Burns effect,
I love it.
Since it has been a while I wonder whether there is any new developement
in XnVIEW in implementing this effect.

Ken Burns Slideshow Effect *please*

Post by respublica » Thu Apr 21, 2011 10:54 am

hi
I really love xnview and it's slideshow feature,
but there is one thing missing to make it the perfect slideshow:

The Ken Burns Effect!

Ken Burns Effect basically is a pan and scan across images that is used on TV or "wedding DVDs" etc,
it makes the still images look more alive like a movie.

http://en.wikipedia.org/wiki/Ken_Burns_effect

I have yet to locate a picture-viewer who has this feature,
all programs I found are either web-apps, screensavers (for xp/2k), or video-producing tools.

If anybody can point me to a picture-viewer with this featuer I would be glad,
and of course, I hope that XNVIEW will implement this in the future.
thank you!

In the example in the original post the image is just zoomed in/out. As metioned in some of the posts above, it's also nice to see zooming in/out combined with a slow moving/panning of the image (left, right, up, down, or combinations of that).
An example of that combination can be seen here:

I know that Ken Burns effect from Picasa. It needs a powerful computer which maybe a problem when showing pictures with a notebook.
At the first view, it's nice. But somewhen you notice that in half the pictures it zooms to a region which is simply the wrong one for that certain picture.
Plus, when you have some text in that picture, it happens that some parts of it never show up.
So this effect makes much more sense if one can define where to zoom - for each picture...

Best Regards,
Karsten

Right, Karsten, Ken Burns may work for many pictures, but an "Auto-Ken-Burns" may result in wrong zooming (zoom in or out) which might look not so nice. There should be random zoom point, smart zoom (if feasable zooming point should be a person or some other area of interest which is automatically recognized by XnView), user-defined zoom position. Perhaps the nine positions (Top-Left, Top-center, Top-Right, Center-Left, ...) plus a fine definable zoom position (e.g. percent from left + percent from top). Sure enough zoom point should be definable per picture.

I now really want to see this feature in a future XnView MP :) :P

Yes and I think Android 4.0 ICS Gallery's 'SlideShow' has this effect too.

btw, I think this topic should be considered next to my SlideShow reqeust of 'Effectual Darkening':

Just a thought, perhaps the XnView MP "Spotlight" tool could play an interesting role within a Ken Burns effect SlideShow. I think it would be cool.

More ideas for 'Ken Burns' enhancements if implemented into future XnView:

• Bounce effect panning
• Bounce effect zoom after panning (with speed setting)
• Face detection zooming after panning
• Zoom then 'glow' light effect on area zoomed
• 007 James Bond-like spotlight
• Shake 'clumsy-focus' zoom after panning (with control setting) :- http://www.youtube.com/watch?v=P-DJdgrsZaQ
• Large step zoom (examples used at end of one part2 simpsons episode)
