Please don’t lock this post! Yes I know that the entire movie isn’t going to be in the 1.9:1 aspect ratio.
I’ve looked through this forum and other places online, and tried whatever solutions/workarounds that other users have tried, but nothing has worked for me. This includes going into the browser and starting the movie in the specified format, then going into StreamFab and downloading it in that format. I’ve tried clearing the cache, clean uninstalling the program, logging out and back in again, and I also was on version 7.0.0.8 when this started.

I specifically choose the IMAX Enhanced version under “VERSIONS”, select Dolby Vision and 3840×2160 at the highest bit rate available, and the program says that it downloaded the IMAX Enhanced version, and the video that gets downloaded has “IMAX Enhanced” in the file name. However, when I go to play the video, I see that these 4 movies specifically do not have any of the IMAX Enhanced scenes at places/times where they should. I have working versions of these movies at 1080p that I have used for testing what I should be getting vs what the program is actually downloading. I want to get them at 4K with Dolby Vision but they refuse to work.

1) Black Panther (the first IMAX Enhanced scene is the opening scene).

2) Avengers: Infinity War (the first IMAX Enhanced scene is the Marvel logo at the very beginning).

3) Ant-Man and the Wasp Quantumania (the first IMAX Enhanced scene is at 13 minutes 20 seconds).

4) Captain America Brave New World (the first IMAX Enhanced scene is at 3 minutes 20 seconds - Brave New World title scene).

If any of these are downloaded in H264 at any resolution, the example scenes listed above are in the IMAX Enhanced format. The exception is Ant-Man and the Wasp Quantumania; it should have IMAX Enhanced scenes (with one noted above for testing), but specifically selecting the IMAX Enhanced version of Ant-Man and the Wasp Quantumania in H264 at any resolution does not seem to download the format correctly.

I am using the latest version of StreamFab (7.0.1.1) and I cannot get these 4 movies to download in the IMAX Enhanced video format if H265 is selected. The resolution, and whether it’s SDR, HDR10, or Dolby Vision that are selected doesn’t matter.

All other IMAX Enhanced titles download fine and have their respective scenes with H265 at 4K with Dolby Vision. It’s just those 4 listed above.

Here is an example with Brave New World at the same time. The one on the left is the working H264 1080p file and the one on the right is the H265 4K DV file. Both are supposed to be IMAX Enhanced at this scene but only the left one is.
