Improving iMovie ’11 web exports, while meeting the compatibility requirements of video-sharing sites
You can eliminate color-banding by exporting your iMovie ’11 video using one of the higher quality compression type Quicktime offers, namely, Apple ProRes 422; however, the size of the exported movie will probably exceed the limitations imposed by most video-sharing sites, including YouTube, Vimeo and Facebook—sites to which iMovie ’11 provides direct uploads. Even without this limitation, the lengthy download times will likely frustrate your online audience.
Fortunately, Quicktime Player X can export movies with the same high-quality afforded by Apple ProRes 422 compression, even while maintaining the smaller size of H.264 (or MPEG-4) compression. Quicktime Player X can even export the movie in a format compatible with the aforementioned sites, as, strangely enough, it uses H.264 (or MPEG-4) compression.
- On the Share menu in iMovie ’11, click Export using Quicktime, and then click the Options button, making sure that Movie to Quicktime Movie is selected on the Export drop-down menu first.
- To use Apple ProRes 422 (HQ) compression, click the Settings buttons, which located in the Video area, and then select Apple ProRes 422 (HQ) on the Compression Type drop-down menu. Click OK.

- Next, click the Filter button, also located in the Video area, and then select the CIE RGB option on both the Source profile and Destination profile drop-down menus.
- Open the exported movie in Quicktime Player X, and then export it using the 480p format.
