It isn't "true" 1080p (or it might be, at least it isn't on the latest Bleach episodes) but in fact 1080i due to the inability to send a full 1080 image through the satellite/cable interface of TVs. That's why the channels sends interlaced 1080 instead. This is easily seen on vertical movements on anime episodes on supposedly the 1080p setting. As I previously mentioned, the latest Bleach episode shows the horizontal stripes briefly during vertical movements that identifies the source as using interlaced scan.

If this is just limited to Bleach, or is true for the 1080p setting overall, I can't say. Though the second would most likely be true unless the TV stations rerenders every single episode using a 1920x1080 resolution with progressive scan for devices capable of transmitting and receiving "true" 1080p.


Here is a screen shot from the latest episode of Bleach at 1080p streaming on Crunchyroll. I tried to find a scene with a ton of movement. This scene has a lot of vertical and horizontally moving black boxes.

You can see typical compression artifacts on the black color, but that is expected of streaming content that is highly compressed. What you do not see is any interlacing. A good example of this can be seen here: http://en.wikipedia.org/wiki/File:Interlaced_video_frame_(car_wheel).jpg

that car image, of course, is an extreme case. I am quite familiar with it, having owrked with telecine and inverse-telecine processes a lot. As far as resolution goes, though, here's the thing: 1080i is actually lower resolution than 720p. It's got less vertical resolution, and if this was 1080i, it would be blatantly noticeable, especially on a progressive scan display like a computer monitor.

What I think it happening is that CR is getting ahold of 1080p source material from the anime companies. I think a lot of people run with the assumption that CR's video is the same copies from Japanese TV, and they are obviously not. This is obviously not upscaled.


Saying that 1080i is lower resolution is false. 1080i has lower vertical lines while in motion, but more pixels overall. A 1080i image will be sharper than a 720p image except when it comes to fast motion scenes as 720p can run at a higher frame rate. However, that is not always the case. Top Gear is shot and broadcasted at 50fps 1080i during the studio scenes (30fps 1080i outside of the studio) and the 1080i source looks worlds better and is a lot smoother than the 720p source because the 720p source is broadcasted at 24fps.

If you can find a show that has a 1080i and a 720p source, the 1080i file will always be about twice as big as the 720p video because the 1080i contains twice as many pixels as the 720p file. 1920x1080 = 2,073,600 pixels 1280x720 = 921,600.

Whether the video is interlaced or progressive does not determine how many pixels it has. A 1080i video and a 1080p video both have the same number of pixels. The difference between the two is basically how those pixels are shown on the screen.

I have a question... Are all episodes of Bleach being broadcasted in 1080p? Or just the latest ones?

I think it is something that has only been going on for about a year or so.

But the broadcast quality and resolution doesn't matter for CR since CR doesn't use TV rips, they get the source files directly from the anime studios.

However, Bleach (And most other series) are actually not true 1080p (Even the Blu-Ray releases) as most anime studios use post-processing to upscale the anime to 720p or 1080p because most anime series are actually only animated at 576p (Or something similar). The CG parts are usually HD (As that is something they can easily change), but the parts that are hand drawn are the areas that are usually just upscaled by the anime studios.

However, that is different than someone ripping a DVD and upscaling it to 720p. The way the anime studios do it is going to give a better picture quality. It is also something CR can't control. You will come across a few posts from trolls claiming that CR upscales their HD stream with a lower quality source, when in reality CR streams what they receive from the anime studios without any post-processing of their own. However, if the studios use post-processing, then CR can't do anything about it.

I know that... In fact, I assumed what you just said in your comment the first time I saw a video from CR in that quality... I know that those videos aren't upscales... people just like to troll... they used to think Dattebayo were gods...

My question is Which Bleach episodes are available in 1080p!!

Thanks for your answer...

Thanks! It'd be great if they added previous episodes in that quality, though... But, at least the end of the arrancar arc is in that quality!
