Ken Burns - workaround to zoom in further?

Hi! It seems iMovie has a built-in limit on how far you can zoom in with the Ken Burns-effect. In my case this means when I try to zoom in on a single face within a class photo, I can only get as 'close' as 4-5 faces. Anyone know a workaround for this? Or have I missed a setting somewhere?

this seems to be an iMovie limitation based on other discussions i've read.
only workaround I can think of is to create a 2nd picture cropped (e.g., photoshop) to the zoomed in 4-5 faces size. if NOT done well then I imagine it wouldn't be seamless, but maybe you can hide it by zoom using original photo, pause the zoomed original photo, (add transition if there's a jump to next photo), zoom using newly cropped photo.
here's how i add pauses before and after a zoom.
create ken burns effect for a photo
copy photo with ken burns effect & paste it twice
for the first photo with ken burns effect, change the kb effect to iMovie's "crop"
for the last photo with kb effect, modify kb effect by reversing start & end by pressing arrows next to start (be sure to ONLY press the reverse arrows & not change position of zoom area), change the new start to iMovie's "crop"
i've thought of doing this, but haven't tried it yet.

No question, but a suggestion RE: Ken Burns

Hey all,
I couldn't find an appropriate place to leave "suggestions" for the Apple software gurus who are working on the next version of Final Cut Pro, so i thought I'd air it out here.
It seems that many people utilize still photo montages in FCP projects, with pans and zooms ala Ken Burns. I myself have used them many times in many different genres of video projects (longform documentary, wedding/birthday videos, etc.) I'm curious why FCP does not include a more intuitive method for doing this, other than Motion keyframes, while lower-grade products like iMovie have the feature built in.
What frustrates me the most is the supposed "control" we get with Motion keyframes; yet we also forfeit some control. This is most evident when zooming in/out of a still image. When you start zoomed in (i.e. put an inpoint Motion keyframe at 100% scale) and then zoom out, no matter how slow (outpoint keyframe at 50% scale), the image will always "accelerate" toward the outpoint. Even when using the Bezier curve handlers to ease in/out of the endpoints, it will always seem to "hurry" toward the zoomed out image.
I know the reasons for this are mathematical: when the image is larger in the frame, parameters become magnified and more coarse, thus a 10% move while zoomed out is much faster than a 10% move zoomed in. Still, it seems unlike Apple to disregard the natural, intuitive, visual, human approach to this tool: our eyes should arrive at both inpoint and outpoint gently, rather than like screeching our brakes at a red light.
I watch quite a bit of documentary television, and I can always spot when the production is using Final Cut Pro to zoom in/out of photos. The rates of acceleration, and the patterns created by the final render, are instantly recognizable for those who have been stared at FCP screens for enough hours.
And while I recognize that there are plug-ins available to make zooms/pans more smooth, I am just curious why Apple did not take the time to incorporate this seemingly simple concept into their flagship video editing software.
Anyone have any thoughts about this? Feel free to post or e-mail me.

I use both FCP and After Effects for moves on photos, and I will have to agree that the acceleration is an issue. After Effects has "intelligent algorithms" to deal with this visual phenomenon...to slow down the zoom as it gets further away from the image. Avid has a plugin called PAN & ZOOM that does the same thing...used to have to use a third party app called MOVING PICTURE. That plugin is available for FCP as well.
As for the ease in/ease out options...Iately I find that I rarely want the picture moves to start from a standstill and end on one. I want a constant move. However, I do occasionally want the picture to come to rest and sit for a moment from time to time. And FCP does allow for this, you just have to plan for it.
But After Effects does a better job...and as I said, the speed of the zoom could be dealt with better. But post that at the link Pat provided.

Photo Settings not showing up; cannot remove Ken Burns effect

Hello,
Earlier today, I selected the photo setting button and a little box showed up with the Ken Burns effect options in it, however now when I select photo settings, the only thing that shows up is the preview of the of photo zooming/panning. Please help... how do I get back to that little box so I can remove the Ken Burns effect from my photos! Thanking you!

Also having the same problem. When going to show photo settings, it shows black screen. Un checking Ken Burns and updating does nothing. All photos in slide show have same super zoom of Ken Burns with no way to remove it or alter it.
iMovie HD broken, iMovie 08 ***... The only reason I purchased Mac was for handling media and I end up doing projects on my old pc using photoshop elements.

Low quality when using Ken Burns effect

Hi,
I tried to import hi-res photos from iPhoto 6 to iMovie HD 6, adding some zooming with Ken Burns. The resulting clips are very blurry, lots of artefacts - very low quality. Is anyone else having this problem? It happens on my iBook as well on my iMac. Or am I just expecting to much?
Thanks for any advice, Patrick

Hi Sue,
Have you ever tried Photo to iMovie? Apple even recommends it.
Yes, I know Photo to iMovie. But if I buy an integrated solution like iLife'06, it makes no sense to buy additional shareware programs to correct some flaws of it.
Isn't it possible to raise the quality of a Ken Burns effect, I would say in iLife '05 it was much better.
So I am looking forward to an update of iMovie HD 6...
Kind regards,
Patrick

Ken Burns: make final crop size same as crop coordinatesin next clip

I have split a clip at a certain point, say 2 seconds in.
I have a Ken Burns crop for the duration of the first two seconds so the final frame is cropped to the (red) end frame. I want this to flow seemlessly into the next frame, which has just had a normal static crop applied. I can see the crop coordinates for this, so I preseume I need my final frame of the ken Burns crop to match those coordinates so as not to get a sudden jump when it goes from the last frame of the Ken Burns crop to the first frame of the static crop.
Alternatively (popssibly better) would be not to have to spliut off the first two seconds, and make the ken burns effect last just for that duration and then stay static on the end crop size.
(I hope I'm making myself clear)
Can anyone help please?

You can't slip the clips and make the Ken Burns effect seamless. Why are you splitting the clip? If you can avoid that it would be better.
OK, then as in the second part of my question, can I make the Ken Burns last for just the first two seconds. I can't find a way to set the duration, it seems to last the whole duration of the clip, that's why I split it because I wanted to pan/zoom with ken Burns for two seconds then stay with the final crop.

Why does "ken burns" increase speed going in/out?

If you've used Flash, you know that you can control the motion by 'easing in/out', that is, the constant and consistent motion of a picture or object can be emphasized at the start or end of a tween (move slow and increases in motion speed towards the end, or vise versa).
the ken burns effect shows a normal smooth motion, maintaining consistent speed throughout the whole motion, ONLY in the preview pane. When it is actually rendered, for some reason some photos start their motion really slow. Others start their motion really fast. Why is this and can it be controlled?

Welcome to the forum, Chris.
Yes, the accelerating zoom of Ken Burns is a known problem. Here's another thread discussing it, with some suggestions. Unfortunately, there is no perfect workaround.

Jerky ken burns zoom

When you empty the iMovie 6 Trash, there's a bug that (inappropriately) discards the copy of the source image iMovie stores inside the project. That makes it impossible to Update the clip later. When you try, that turns the clip black.
Lots more here, with some workarounds:

Jerky Ken Burns effect

I am using iMovie 10 on a mac desktop with all the latest software. In some photos in my 4 min video, the Ken Burns effect is jerky, even after sharing the video to a .mp4 file. The photos are of good quality and resolution (I use iPhoto). Is there a way to smooth the zoom effect?
I made a sample clip (5.7MB) but can't post it here, apparently.

Even though my stomach turns when people call a move on a still "The Ken Burns Effect," I'm going to supress my revulsion and try to assist.
The blurriness MIGHT come from a pref "Default Scale to Frame Size, which makes the scaling on all your imported / placed images 100%. This is a defect in the way Pr was built, IMO. There's no good reason for Pr to think a huge photo is 100% scaled, just because it fits nicely in a Comp view. It misleads users into thinking they're out of resolution, when they're not. So, my first suggestion is to turn off that pref (uner General) and see the difference that makes when you know exactly how much resolution you have to deal with. Then, don't go over 100%.
I can't envision the jerkiness you're describing. It could be an interlace issue, from how you describe it. If that's the case, render progressive.

IPhoto slideshow export -- Ken Burns "jerkiness" on playback

Have an iPhoto slideshow of 25 pictures. On some, I used Ken Burns effect to zoom in, out, etc.
When I export, the result is a .mov file. Everything looks great when I play it on Quicktime, except for some of the photos on which I had used Ken Burns (meaning there's motion). The bad ones don't render properly, and are "jerky" for lack of a more technical word. They get stuck for a couple of seconds, jump forward, get stuck again, etc.
Amazing thing is that I did an export out of Quicktime using Sorenson3, and that seems to have smoothed everything out in a nice way. Result is a movie with no jerkiness, and everything works right.
Two questions:
1) Can I count on the Sorenson3 export method to fix the jerkiness for three other iPhoto slideshow-based movies I'll need to generate, or was this a one-time fluke that Sorenson3 fixed this movie? In other words, is there a principle behind the fix that makes sense and can be counted on?
2) What caused the jerkiness in the first place? Is there something I can do so the original output from iPhoto on Ken Burns photos isn't jerky?
Thanks for any insights.

the audio associated with that set of photos was a piece of music off of an audio CD that had been transferred to iTunes for the purpose of making this section in the DVD. It's not a big problem that the music didn't transfer, since I can add it back into FCX. Thank you so much for your concern and help. This was a very key bit of info that you provided me. Thanks again. bill

Kirk,
Did what you suggested, with some tweaks, and it's working nicely. Exported at 3MB/sec -- 2MB didn't render well enough. Tried MPEG-4, and then Sorenson again, and actually the Sorenson worked better for some reason.
So thanks, and now I have one follow up question: My next step is to convert the file to .wmv format so it plays on Windows Media Player. Must do this for a project at work -- where people are on PCs using WMP.
I purchsed Flip4Mac a while ago for this purpose, and that's what I intend to use. Can I simply convert the file exactly as is to .wmv -- keeping all the goodness of the settings that are now working? Will this be an export of an export that will damage the quality of the result?
Thanks for your thoughts.

How to get Ken Burns effect to zoom out so the whole pic is visible

I want to start or end with the full pic in view - just as the FIT command does.
Then I want Ken Burns to Zoom/pan to make it interesting.
But I can't figure out how to re-size the frame beyond the 4:3 (or whatever is restricting it) ratio.
Tried dragging the frame edges with CTRL, ALT, SHIFT, and COMMAND. Nothing seems to release the constraint.
Thanks in advance.

I want to start or end with the full pic in view - just as the FIT command does.
If by "Fit" you mean the image exactly matches the display area, then you would have to "pre-crop" your scan to one of the available aspect ratios either before or after making your scan. If by "Fit" you mean "letterbox" or "pillar" views, then as Appleman said, you would have to either use the mentioned automator action or almost any graphic application. I prefer the manual approach so I can add a "text" area, frame, texture the background and/or image, and/or create other special effects.
But, how do I zoom the view out past the edges of the photo? If I press the FIT button in KB effect, it does it. But I loose the ability to zoom/pan... Unless there is some trick to getting KB effect to start or end with a FITted picture?
There isn't. iMovie '08 automatically scales the content to make the smallest dimension "fit within" the display area and, therefore, does not allow the "over-zoom" effect of "fitting" the larger dimension within the display area. You can however do this in iMovie HD. So if you want the "built-in" capability, this is a case where you should be using the the older application -- otherwise you will have to letterbox/pillar the content to get iMovie '08 to "Fit" your image as you wish.

Jerky Ken Burns when burning to DVD

Hi all - tried finding an answer to this but not much luck - anyway the problem is I made a simple movie in imovie 08 using only photos, music and Ken Burns effect on some pics. the presentation runs smooth as silk on my iMac 24" - so then I try burning the movie to DVD using iDVD. I slot the DVD in a player and it looks very average. The picture resolution is low - should I export to a higher level of resolution? Then the Ken Burns effect is jerky - not massively but still not smooth. Please help I really want to be able to export/burn movies that look great and run smooth but can't find out how to do this,
thanks in advance
Rob

I have the same problem. Ken Burns looks good on the computer but real jerky on the DVD using iMovie 8.

Pan and Zoom (Ken Burns Effect)

Does iDVD 06 support the Ken Burns Effect? When I import a Slide Show from iPhoto to iDVD it looses the transitions and the pan and zoom features. I can add the transitions back through iDVD, but I can't find anywhere to add the Ken Burns effect back to the slide show? Is it possible? I will be really disappointed if iDVD 06 does not support this feature.

Welcome to iDVD Discussions.
I don't use iPhoto, so I can't help you with that, but I can tell you that iDVD does NOT have the KB Effect.
