@Sadlylate Alpha channel formats still work in VEGAS. Quicktime decoding functions and other formats are migrated to the native decoders like Apple ProRes.

This seems to contradict this comment made by a member of the VEGAS Pro team recently:

The File I/O Surrogate was rewritten with the release of 23 and its only existence is to handle Quicktime decoding. If Apple ProRes now handles the decoding natively then I'm wondering what the actual purpose of the I/O Surrogate is for or maybe I'm misunderstanding something somewhere

Yes, I think my comment was imprecise. ProRes is decoded natively as are more snd more formats. QuickTime still does DNxHR and a few others that have yet to be migrated.

@thesammy58 Just to be clear, the developer's statement about the File I/O Surrogate is, "It is still needed if you enable the QuickTime decoder." I understand that to mean that if you don't install QuickTime decoding drivers and enable them in Deprecated Preferences, the File I/O Surrogate could be completely removed from Vegas. But my experience is as @RogerS mentioned... Vegas cannot process DNxHD without both QuickTime & Avid drivers installed and QuickTime decoding enabled.

Hello, I took advantage of a promotion to buy Vegas Pro 23 on the official website https://shop.vegascreativesoftware.com/ I knew that the French version was not working, so I installed it in English version, but after the installation, the software systematically gets stuck! 😦

Hoping to have a solution / Thank you for your help, beautiful day
