How to change movie dimensions in iMovie 10?

The only way that you can change the size of the video/movie is when you export/share your project

480x480 is no standard complying aspect-ratio of any video ...

why should any editor support that? 😉

the classic free converter Mpeg Streamclip allows you to crop, squeeze and export to any resolution you like. Export from within iMovie, import and convert it.

Video files are always wider than tall and there has never been a 480X480 size in any version of iMovie.

What creates a 480X480 source file? Are you using still images that you custom made?

The highly-popular 6-second Vine videos are in 480x480 format. You can use iMovie to edit your 6-second movie, but you cannot export it as 480x480; you have to export it in larger size and then use a 3rd-party app to crop it to 480x480. It would sure be nice and time-saving if this could simply be done within iMovie.

Hello Karsten Schlueter,

Thank you for your advice on 'MPEG Streamclip' being able to "crop, squeeze and export to any resolution you like".

Where do I find these wonderful menu options in the MPEG Streamclip 1.9.2 Menu bar/Drop menus, please? Despite many efforts to get to these menu options, I have always been unable to locate them.

Gratefully, Ranger 1.

After opening your iMovie-export, you first have to decide mov or mp4 or whatever under 'Export as (here: Quicktime)'

You then get promped the Option dialog:

here you can dig into options.. resolutions, even 'free' ones (as 480x480), you can zoom-in, change the x/y aspect ratio, crop etc etc...

in the beginning, it needs some trial'n error to find out, what button has which effect. Don't start with you 2h Hollywood project, render a minor 7sec clip for test-purposes. Write notes, what you've set where. Make use of Streamclips Preview feature. Finally, you can save and use your own Presets.

not sooo Mac-like in its GUI (=I'm more used to 'handles', or 'pic buttons' for example), but an incredible tool, #1 on my list. And for free! ...

Lieber Karsten Schlueter (I don't know how to type an umlaut on my Mac keyboard, sorry),

Danke sehr for your generous advice re 'MPEG Streamclip's video converting and dimension changing capabilities. I once opened the dialogue window you showed when I accidently pressed "CMD SHIFT E" when trying to take a screen shot, while 'MPEG Streamclip' was the active application. As it was not the desired action at that time, I did not investigate the potentials on offer.

I apologise for my late response to your kind reply but I have been preoccupied with the final illness/passing of my beloved, little dog 'Bubby'. Einschuldigen Sie mich, bitte.

Following earlier advice on the subject of altering a video clip's dimensions, I downloaded 'iMovie' Ver. 10.0 as it is no longer included in OS X Mavericks installation. Is Apple more closely following Microsoft's commercial/profit ethos with each new OS X release, or is it my imagination?

Again, due to my recent preoccupation, I will need to investigate the intricacies of iMovie capabilities to manipulate video formats, output capabilities etc. at some stage.

Schoenen dank for your welcome assistance. Hoping you are welll, I remain

Yours sincerely, PaulRanger 1.

getting off-topic here, but, .. wrong impression:

iMovie was never part of the OS, nor OS-updates/upgrades! Always sold individually, upgrades (flat numbers, vers.3/4/5/6/08/09...) always cost, part of iLIfe, since AppStore single app to buy.

reg. MS: you get iWorks (Numbers, Pages, Keynote) for free, you got the latest iLife apps updates (if qualified) for free, you got a whole OS upgrade for free... MS = you have to rent (!!) their products! Anything you write in latest Office will not be usefull in 5y, if you quit to pay your anual fee... 😠 Windows 7 >> 8 = $$$ etc.

Sad to hear about your dog ...

finally: try opt-u while typing my name 😉

Hello Karsten,

I thank you for your response to my earlier questions and erroneous allegations re Apple’s current marketing philosophy. I was mislead by reading members' comments on other Mac support forums that iMovie had once been integral to an OS X installation. I apologise for any perceived, derogatory comments that were seen to be aimed at Apple.

My frustration with continuing OS X operational difficulties (massive data loss, folder and/or folder content disappearence, system instability, increasing loss of confidence in OS X) since I was forced to install Mavericks 10.9.2 (10.9.1 had installed worked fine) may have tinged my negative response.

I thank you for your kind sentiments concerning my little dog.

Being over the Easter period, I will withhold further contact attempts to Apple support until Easter Tuesday. Until that time, my iMac is almost unusable.

Again, thank you for your responses.

Sincerely, Paul Ranger 1.

I have had a similar problem my, so I opened it in keynote and changed the dimensions in there. Probably too late for you, but it may help someone.

I just shared a standard iMovie as a file and imported to Vine and it autocropped to a square for me 🙂

Hi

You can change the size by using ffmeg utility as well :

ffmpeg -i Movie1.mov -vf scale=1080:1920 Movie1_iphone6s.mov

You can click the vid and zoom out so it fits, but then you'll have black sides. But that mite b ok
