By 2008, both Apple hardware and operating systems fully-supported 64-bit applications, while at the same time, also running older, 32-bit applications. And, when it comes to media files, 64-bit system support is necessary for larger media frame sizes and larger project frame sizes, such as 4K and beyond.Īpple began converting from 32-bit to 64-bit hardware in 2003. The 64-bit Intel architecture is significantly faster than 32-bit. Here’s an article that explains how to do this.Ħ4-bit systems can access vastly larger amounts of memory. This allows you to run both an older version of the macOS alongside the current version. NOTE: Another option is to create a dual-boot system disk. Waiting a few weeks before upgrading to allow yourself time to research any potential problems will be time well-spent. It is always better to proactively convert older files than discover, after you’ve already upgraded, that the files no longer open.īefore you upgrade your editing system to a new version of the macOS, such as Mojave, take time to make sure that your legacy files and applications will still run properly. Digital Betacam shot 4:2:2, Betacam SP and DV shot, essentially, 4:1:1, while DVDs were 4:2:0.īecause older 32-bit applications and older codecs will not be supported forever, it is essential to convert older files into newer codecs in order to retain access to our historical media. It easily supports any original source resolution of our media files.Ī key reason I recommend ProRes 422 for camera media is that standard-definition video was shot in a 4:2:2 color space or smaller. NOTE: One of the benefits of ProRes is that it is resolution-agnostic. If you are converting files created on a computer, either with or without an alpha channel, ProRes 4444 is the codec I recommend. Most legacy files are SD (standard-definition), so, when converting files shot with a camera, ProRes 422 is an excellent archive choice. To prevent losing access to our history, we need to convert older legacy media files into a current 64-bit codecs. This means that at some point in the near future, older 32-bit applications and media files won’t open on current systems. This is really important, so let me get right to the point: Digital media archives must be managed.Īpple is completing the transition from 32-bit to 64-bit hardware and software that it began 15 years ago.
