The good news – we have the second Avengers Endgame trailer in 4K. The bad news – it is not in the IMAX aspect ratio, but the Scope aspect ratio of 4096×1716. I know that IMAX released the IMAX ratio on YouTube, but I have been unable to get a high quality source. If you have a 4K display, then this version should be an immense upgrade over the 1080p version previously released. As I did with Trailer 1, I switched the titles cards (The Avengers Endgame Logo and Release Date Information at the end) with the 1080p source upscaled to 4K. I did that because the 4K source was not English. The other change related to the audio. Since the source was not English, I multiplexed an adjusted version of the English audio from the 1080p trailer. It was adjusted to play at 24fps to match the 4K video, instead of the 23.978 frame rate of the 1080p version. As mentioned in earlier posts, I did not do a 10 bit HEVC encode because I am unable to encode HEVC at a high bit rate (greater than 10 Mbps) without introducing some playback issues such as jittering. Therefore, I am sticking with the AVC 8 bit encode. I did however, increase the bit rate for this 4K version to 40 Mbps to improve the overall image quality. I am really happy with how it looks, and I think you will too.
We are now less than a month from the release date and my son and I are totally stoked for it. I really appreciate that these trailers for Endgame have not given away too much information and the movie should have a lot of surprises. You can get the 4K trailer 2 at the Avengers: Endgame (2019) page as a .mkv with DTS-HD Master Audio 5.1 or a .mp4 with AC3 5.1
This one is currently in my home cinema playlist and will be for quite some time…at least until we get the first trailer for Episode IX.
