Who wants the IMAX version of the second trailer for Avengers: Infinity War (2018) with the full 1.9:1 aspect ratio? Well, if you do there are three versions available: A 4K (4096×2160) mkv with PCM, DTS and AC3 5.1 encodes; a 1920×1080 mkv with PCM, DTS and AC3 5.1 encodes, and a 1920×1080 mp4 with AC3 5.1 audio. The 4K version is large at 1.5 GB.
Some people are still asking about playback on the PS4. I have confirmed that these files, and likely everything I have posted in the past two years will play on the PS4. For playback on a PS4, the USB stick must be formatted as FAT32. Nothing else will work. Secondly, you can not have the files in the root directory, they must be in a folder. It does not matter what the folder is called — it just has to be in a folder. If it still does not work, update your version of the PS4 Media Player.
