Avengers: Endgame (2019) Trailer 2 4K 4096×1716 DTS-HD MA and AC3 5.1 8

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!


Transformers: The Last Knight (2017) Trailer 2 1080p and 4K UHD – PCM, DTS, and AC3 5.1 4

Transformers: The Last Knight (2017)

I am pleased to present our first movie trailer in 4K UHD, and it is the latest online trailer for Transformers: The Last Knight. The 4K version is available as a .mkv file, and I transcoded it with a bitrate somewhere around 50 Mbps. The master had a bitrate of over 500 Mbps and was over 11 Gb in size. If you have the set up to handle it, I think you will find those IMAX shots in UHD to be quite stunning. The 1080p version looks and sounds great too. This could be the best Transformers movie yet.

Will we have the first trailer for The Last Jedi tomorrow?

Here are the details of the UHD Source for those who like such things:
Format : ProRes
Bit rate : 565 Mbps
Width : 3 840 pixels
Height : 2 160 pixels
Stream size : 11.2 GiB (100%)
Color primaries : BT.709


4K UHD Blu-ray discs to be available March 1, 2016

4K UHD goes from streaming to high quality physical media

March 1 is now less than 3 weeks away, and this is the day when the first batch of 4K UHD Blu-ray discs hit the streets, in what promises to be the best video presentation in the home to-date. Physical media, not being constrained by the bandwidth limitations of streaming services are best suited for the large file size and bit rate of 4K Ultra HD video. The UHD Blu-ray spec allows for three disc sizes: 50GB with 82 Mbps bitrate, 66GB with 108 Mbps, and 100GB with 128 Mbps.  For comparison, Netflix streams 4K somewhere around 15 Mbps.

 

HDR – What is that all about?

You may have heard the term HDR being used a lot lately. HDR is “High Dynamic Range”, and many of the first UHD Blu-ray discs to be available will be mastered with HDR. This provides a greater level of contrast – whiter whites, and blacker blacks, for a more life like picture. While the discs will be HDR, and UHD players HDR compatible, current 4K TVs for the most part — are not. So, if you are in the market for purchasing a 4K TV, you may want to wait until later in the year, because HDR will be what you want. If you already made the jump to a 4K TV….well, things will still look good until you upgrade. If you do not care about HDR, you may also be able to save quite a bit on existing sets once the certified sets hit the market.

I want to buy a new 4K TV, how can I tell if it meets the HDR standard?

Ultra HD Premium

Ultra HD Premium

The easiest way to be certain, is to look for this logo. The “Ultra HD Premium” Logo will appear with TVs that meet the HDR standard set out by the UHD Alliance. Just to add some confusion, there is also Dolby Vision, which is Dolby’s version of HDR. Dolby Vision has support from LG, TCL, and Vizio on the manufacturing side, and Universal, Warner, MGM, and Sony on the studio side. Dolby Vision is a more advanced spec, and requires compatible Blu-ray players as well as Dolby Vision mastered content. The good news is that Dolby Vision equipment still meets the Ultra HD Premium standard – but not the other way around.

Dolby Vision will likely come with a higher price tag to Ultra HD Premium. So, if you are interested in getting the best possible picture and are not concerned with the cost – waiting for the Dolby Vision TVs, Blu-ray players, and Blu-ray discs may be your best option.

4K UHD Blu-ray discs available for pre-order

If you have a 4K TV and want to start watching content on March 1, there are several titles available for pre-order, including The Martian, Kingsman: The Secret Service, and Hitman: Agent 47. You can pre-order those (and more) here: 4K UHD Pre-Orders

Watch out for 4K Upscaling players!

A warning on players!  There are a lot of Blu-ray players out there that are listed as 4K Upscaling players. Those are not 4K UHD players. Those have software that convert a 1080p source to 4K. They are not native resolution, and will not playback any 4K UHD Blu-ray discs.

 

I hope that this information has been useful to you. It is always confusing when new standards and products hit the market, and I wanted this post to clarify some new concepts without being too detailed. If you think that I have made any errors in my assessment please let me know.
