IMAX Infinite Worlds 4K HEVC HDR Rec2020 DTS-HD MA 13

IMAX Infinite Worlds Pre-show Trailer DTS-HD MA 5.1

IMAX Infinite Worlds

New versions of IMAX Infinite Worlds have been added to the IMAX Pre-Show Trailers page. This replaces the version that was posted in July. There are a number of differences from the July version. The audio of the new version is much better than the previous version, and I suspect that the July version was not an official mix. The resolution is also better, where the July had 2732×1438 (1.899 aspect ratio) the new version is 3840×2026 (1.895 aspect ratio). I also did some editing to give a buffer at the beginning for smoother start of playback. Another major difference is that this time there is an HEVC 10 Bit HDR Rec2020 version as well. This is my first attempt at color grading and I could not have done it without the help of Sergio Novelli. While we are mostly happy with the results, I am sure not everyone will be. But please keep in mind that this is a first attempt and the process will continue to be refined. So, head on over to the IMAX Pre-Show Trailers page and check them both out. I also want to thank Johann for sending the new version along.

THX GENESIS UHD Trailer DTS:Neural Upmix encoded in DTS-HD MA 5.1 and AC3 5.1 8

THX 2019

THX 2019

I have been meaning to post this for some time, but it just kept getting pushed down the pile. The THX Trailers page has been updated with eight (yes eight) versions of the new GENESIS trailer. The earlier file that was created from the YouTube encode is still there. The eight new files were created from a very high quality master, which also contained a PCM stereo track. I created a DTS:Neural UpMix from the PCM Stereo and it sounds fantastic. There are eight files because I also created a scope version for those who have a widescreen projector, HD versions for those who have requested HD instead of 4K, and MP4 versions for those who can’t use MKV files. There should be something for everyone. You can find the THX GENESIS trailer at the THX Trailers page.

THX 2019 4K Trailer DTS:Neural Upmix encoded in DTS-HD MA 5.1 and AC3 5.1 5

THX 2019

THX 2019

I wasn’t expecting this, but THX has dropped a new trailer to celebrate their 35th anniversary. However, I am confused as the first film to undergo any THX quality control was Return of the Jedi, and that was 36 years ago (1983). Perhaps that was an experiment and a year later it was officially launched. If anyone knows for sure, please chime in. Do you know what the acronym THX means? It stands for Tomlinson Holman Experiment, after the sound engineer of the same name who developed the THX sound system. Tomlinson Holman also developed the first 10.2 sound system.

The new THX trailer does not have a name yet, but because it is 2019, there is a Twitter Poll for the fans to select the name. I see Trailer McTrailerface was offered as a suggestion. Also, because it is 2019 the trailer dropped on YouTube and offers what THX calls “THX Spatial Audio” which provides a “deeper immersive audio experience with headphones or earbuds”. I am not sure how that works since watching and hearing the trailer via YouTube provides only a stereo experience. But that doesn’t seem to matter these days judging by the endless array of comments praising the sound of Dolby Atmos trailers on YouTube.

If you want a better experience than offered by YouTube I did some work on the YouTube encode. I did some processing on the video to remove the banding artifacts. And I did a DTS:Neural Upmix on the THX Spatial Audio (Stereo) track which turned out to be really immersive. Compared to the experience of watching on YouTube, one could be forgiven for believing it was a true 5.1 mix. I am hoping that in time this will arrive properly on blu-ray, but until then this is the best out there. You can find the THX 2019 trailer at the THX Trailers page.

Dolby Vision Trailers

Dolby Vision

The Dolby Trailers page has been updated to include a number of Dolby Vision trailers. All files have two video tracks, one with UHD 2160p and one with HD 1080p. Both video tracks are encoded in H265 HEVC Level 5.1. 10 bit Rec 2020 color space, mastered with max luminance of 4,000 cd/m2. On the audio side, there are three options. Dolby TrueHD 7.1 with Atmos, Dolby Digital Plus 5.1 with Atmos (EAC3) and Dolby Digital 5.1.

The files added are Core Universe, Escape, Pufferfish, Chameleon, and Leviathan. They can be found on the Dolby Trailers page.

Dolby Atmos Nature’s Fury – TrueHD ATMOS 7.1 12

Dolby Atmos Receivers

Thanks to a kind visitor to the site, we now have a much better quality of the much sought after “Nature’s Fury” trailer in Dolby TrueHD ATMOS 7.1. You can find it at the Dolby Trailers page.

I also added some direct links to the IMAX 4K and 1080p versions of the Avengers: Endgame (2019) first trailer as some folks have been having issues downloading from We Transfer. This should take care of that.

I have been asked about John Wick 3, and I have put together a nice up mix of Trailer 1, but I am still hoping to obtain an official mix. If I don’t get it today, I will upload it tomorrow. Stay tuned.


Dolby Atmos - Nature's Fury 5.1 Audio

Dolby Atmos – Nature’s Fury DD+ ATMOS Audio

The Dolby Trailers page has been updated to include Nature’s Fury with Dolby Atmos. The original source video was very low bitrate, and contained a lot of banding in the color gradients. I adjusted the video to remove the banding. Compared to the original, it is a bit darker, but I think it looks better. The audio on this is DOLBY ATMOS, but unlike the other ATMOS trailers I have on the site, this one uses Dolby Digital Plus 5.1 as the base for the ATMOS objects instead of the TrueHD 7.1 that would be found on ATMOS Blu-rays. Dolby Digital Plus 5.1 with ATMOS is used by Netflix for streaming ATMOS content.

DTS Out of the Box Trailers 1080p DTS:X, DTS-HD MA 7.1, DTS 5.1 6



Last week, I saw the 2017 DTS Demo Disc – Volume 21 that was distributed last month at CES for sale on eBay. Since getting it on eBay is a lot easier than flying to Las Vegas I decided to make the purchase. The 2017 DTS Demo Disc – Volume 21, included six new DTS trailers. Three DTS:X “Out of the Box” in 15, 30, and 60 second versions; and three DTS HD “Out of the Box” Trailers, also in 15, 30, and 60 second versions. I am happy to be able to share these with my fellow home theater and DTS enthusiasts! So head over to the DTS Trailers page and check them out. Oh, and if you do not have playback capability for DTS:X or DTS-HD MA, the second track contains the lossy DTS 5.1 encode.

I also added the DTS:X Object Emulator, which is a nifty demo showing an object (a ball) moving in a 3D space and the sound in your home theater matches the location of the object. It has a nice beat too. How fun is that?
