@RogerS Hi, I can't go into details but iPhones create .MOV HEVC files, there was a post somewhere, maybe it was on the Magix forum where looking into it I read things online like 'requires HEVC video extension' & 'requires Quicktime to play these properly'.

@Chocabo-corndog MediaInfo of the file would show whether this is .MOV or ...

The App is called MediaInfo, download it, it's free & a fast download with no added adverts or any of that rubbish. https://mediaarea.net/en/MediaInfo.
After downloading, right click on the media file in your Windows folder, open MediaInfo, choose Text from the options at the top, drag the edges of the window that pops up so it shows all the information & screen capture that page, post that image on here using the arrow button next to the smiley at the top of a new comment 👍

Or Copy & paste the information in a new comment like this -

The container really shouldn't matter.
Canon DSLRs also created .mov (AVC) files and VEGAS opened those without issues from the beginning.
ProRes is also mov and has worked in VEGAS for many years without QuickTime.

"Support for HEVC 10-bit BT.2020 and BT.709 files" came with VP 16.
HLG support came with VP 17.
VP 19 had "Issue with black frames when using HEVC media is resolved"

There were various decoding bug fixes along the way and I can't recall if any of these impacted iPhone media.

@Chocabo-corndog If you cannot play hevc after reinstalling Windows, It's likely because you also need to reinstall the Microsoft hevc entensions which are typically preinstalled by oems. I have a couple of old official oem hevc driver extension packs that you can try here, which might work depending on which version and build of Windows you reinstalled: https://drive.google.com/drive/folders/1DPx86A1zHZFjqTAID8M10I8Kwp2wpi-o?usp=drive_link

If neither of those versions work on your version of Windows, the Microsoft store version may be more current: https://apps.microsoft.com/detail/9nmzlz57r3t7?hl=en-us&gl=US

Thank you for the response and the google drive link.

I can play HEVC files outside of Vegas Pro 18. However, inside Vegas Pro 18 they would be blank videos with only audio. Once I installed QuickTime it resolved this. With QuickTime uninstalled it breaks again.

I have bought and downloaded the most recent version from the Microsoft store (https://apps.microsoft.com/detail/9nmzlz57r3t7?hl=en-us&gl=US) and restarted my system. Still needs QuickTime installed to work oddly. That is a separate issue at this point.

Regardless, I have isolated the issue to cinematic mode on the iPhone 13 pro. My tests shows that normal HD videos were fine but cinematic videos were messed up. See below.

Next example is cinematic video from iCloud on top and after rendering below.


Note: It looks the same way (washed out) as soon as I import the media into Vegas Pro 18. It isn't a rendering issue.



 

VEGAS shouldn't need QuickTime for HEVC though I haven't tried newer phone formats with 18.

It sounds like the footage you are bringing in is HDR from an iPhone? There was just a thread on this recently. 32-bit ACES with the color space set to HLG might be a starting point. Then adjust curves, saturation, etc. to taste.

I've also seen LUTs for iPhones to convert to Rec709 (for that you need to turn off ACES/ "view transform off" or use the 8-bit full project mode).

In general not shooting in HDR, especially if you don't have an HDR computer monitor to view them on anyway, makes for an easier workflow.

I see what you are saying. This is for Iphone 13 Pro. The footage is from Cinematic mode. Normal HD videos come into Vegas Pro 18 just fine. The issue must be with the Cinematic mode footage. I will look into this more but I appreciate the good starting point. I will try to avoid shooting in Cinematic mode for now.
