Last week, news broke of security woes in the Windows version of QuickTime that Apple had no intention of patching. Apple has now confirmed that it has ceased developing QuickTime for Windows and will not offer security patches for the issues. The impact on PC users will depend on which software packages you use, but one major vendor, Adobe, has noted that there are certain file formats it can’t support yet without relying on Apple’s QuickTime.
The Adobe Creative Cloud team describes the situation as follows:
Adobe has worked extensively on removing dependencies on QuickTime in its professional video, audio and digital imaging applications and native decoding of many .mov formats is available today (including uncompressed, DV, IMX, MPEG2, XDCAM, h264, JPEG, DNxHD, DNxHR, ProRes, AVCI and Cineform). Native export support is also possible for DV and Cineform in .mov wrappers.
Unfortunately, there are some codecs which remain dependent on QuickTime being installed on Windows, most notably Apple ProRes. We know how common this format is in many worfklows, and we continue to work hard to improve this situation, but have no estimated timeframe for native decode currently.
Other commonly used QuickTime formats which would be affected by the uninstallation of QuickTime include Animation (import and export), DNxHD/HR (export) as would workflows where growing QuickTime files are being used (although we strongly advise using MXF for this wherever possible).
