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

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.

Star Wars – The Rise of Skywalker (2019)

Thank you all for your patience over the last few months, it has been a crazy spring. I have been working behind the scenes to make some site improvements. I am happy to say that things are getting back to normal, and I do have a bunch of new trailers to post. I meant to put this up a few weeks ago, but it didn’t happen. I got my hands on a foreign language 4K version of Trailer 1 – and like the 4K IMAX Avengers: Endgame trailer I have swapped out the foreign titles for upscaled English from the 1080p master. You will see a lot more detail in the non title scenes. The file is big – 1.2 GB @ 80 Mbps.
Head on over to the Star Wars Episode IX – The Rise of Skywalker (2019) page to get the first trailer in 4K with 5.1 DTS-HD Master Audio


Avengers: Endgame (2019) Trailer 2 4K 4096×1716 DTS-HD MA and AC3 5.1 14

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.

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.

I went through the workflow process to determine what caused the banding issue present in the Avengers Endgame IMAX trailer that I uploaded on Dec 21. From that, I was able to eliminate a transcoding step and now have a version that is much closer to the master. The original source was JPEG2000. In the first attempt, the original was  transcoded to ProRes. The ProRes was then transcoded to H264. Some editing was performed on the H264 encode and the final video was produced from that. This new version used the ProRes created from the JPEG2000 source, and only one transcode to H264 was performed. Now, there is still some banding, but it is comparable to the original 1080p widescreen version. I don’t think I can get it any better.

 

You can get the new 4K version, as well as 1080p .mkv and .mp4 versions here. I have also experimented with H265 – HVEC, but I am not happy with the results. I will keep working on that, but for the mean time, I will stick with H264 – AVC.

In other news, I will also be uploading both Captain Marvel IMAX trailers, however I am going away to visit family so those will not arrive until the new year. With that I wish you a very happy remainder of 2018; and I look forward to providing you with the best quality trailers in 2019!
