Mix dif­fer­ent video res­o­lu­tions

Shoot and com­bine HD and 4K footage in the same iMovie project

Mac|Life - - CONTENTS - Ge­orge Cairns

Your iPhone, and gad­gets such as the GoPro Hero 6 Black cam­era, can record video footage at dif­fer­ent res­o­lu­tions and frame rates. The iPhone’s de­fault video record­ing res­o­lu­tion is 1080p HD at 30 frames per second (fps). This footage looks ex­cel­lent on TV and YouTube.

How­ever, you might want to drop the res­o­lu­tion to 720p HD, to save stor­age space, for ex­am­ple. This smaller HD res­o­lu­tion will still look okay when viewed on so­cial me­dia, but may look fuzzy when com­bined with higher res­o­lu­tion files in an iMovie project.

You can also record slow-mo­tion (slo-mo) clips on your iPhone us­ing the 720p HD res­o­lu­tion. This is worth do­ing to ben­e­fit from a higher frame rate of 240fps, which en­sures smoother mo­tion in a slo-mo se­quence than you’d get by sim­ply slow­ing down a stan­dard 30fps clip, or even the high­est qual­ity 1080p op­tion of 120fps. Slo-mo clips en­able you to por­tray an event or ac­tion in a vis­ually artis­tic or po­etic way, with­out jar­ring jumps be­tween frames.

Shoot­ing 4K gives you footage with a very high res­o­lu­tion. When you use a 4K clip in a 1080p HD iMovie project, you can crop it to zoom in with­out cre­at­ing fuzzy-look­ing pix­els. You can also add Ken Burns zoom and pan ef­fects.

In this walk­through, we’ll talk you through how to shoot a range of dif­fer­ently sized clips and then com­bine the dif­fer­ent res­o­lu­tions into a con­sis­tent 1080p HD project.

Dif­fer­ent res­o­lu­tions can be com­bined in iMovie. Make sure you set the fi­nal res­o­lu­tion when edit­ing’s done.
