Thank you for the response, will consider updating in the future.
As for YouTube, I kept a video for a day and it didn’t change at all, as expected. As you said, it may take a while to do a “post-process” process and display all the available resolutions and apply the 60 fps if available, but it used to take 3 minutes only, not a whole day. I’m pretty sure this new preset is what causes the problem. I’ll try rendering a sample video using the “Sony AVC/MVC” preset and will check the results, posting them here later.
