Export ProRes on iMovie in Easy Steps

The reason to export to iMovie ProRes can be easily explained with a quick question, “Ever experienced extreme lagging while editing a video in the Mac version of iMovie?” You most likely have, and there is a cause behind it.

In Absence of ProRes

Almost all recording devices these days capture the footages in a format that uses a compression-oriented codec (e.g., H.264, H.265, etc.) to reduce the file size, and put less overhead on the GPU and processor during the playback. However, when it comes to editing such recordings, the GPU needs to de-compress them, thus demanding more processing power. Because of this, the videos lag, not only in iMovie but in any post-product application, unless you have a PC with enormous specifications.

In order to overcome this, most professionals transcode the videos to Apple ProRes iMovie can import and use while editing.

How ProRes Helps?

The answer is simple. Since ProRes is a container that stores the visuals in uncompressed form, the additional amount of GPU that was otherwise consumed while processing the files of any other format is now utilized to edit the footage, thus preventing the videos from lagging during the process.

Keeping all the above info in mind and the challenges you may face while editing a clip, this tutorial explains how to transcode footage to ProRes iMovie can use for post-production tasks. The guide also suggests another better alternative to export videos to Apple ProRes iMovie can import for fine and professional-level editing.

More Info

Although ProRes is Apple’s proprietary, the format is now adapted by many application vendors, including Adobe. With this collaboration, post transcoding a video using Wondershare UniConverter, not only with iMovie, ProRes can now be used with Adobe Premiere Pro, Adobe After Effects, and Adobe Media Encoder.

Conclusion

While working with iMovie, ProRes can be quite helpful to edit the footages, and that is the reason the program has a built-in option to transcode the clips accordingly. However, because iMovie is a resource-demanding program, if your Mac doesn’t have sufficient hardware or updated macOS, the application may refuse to run. This is where Wondershare UniConverter steps in as its Mac variant allows you to export the videos to Apple ProRes iMovie can work with. If iMovie fails to run on your macOS, an iMovie ProRes file can be moved to a highly equipped Windows PC, and used with any of the Adobe applications for post-production tasks.
