But the screenshots were a big help, and now I can see what you're talking about.LiLAsN wrote: ↑Wed Sep 05, 2018 6:19 pm All in all, the intro music is nice. However the hindu music feels out of place for a battle soundtrack. Doesn't feel 'epic' as was intended. Doesn't blend well with the fight scene.
I feel sad though. This is the year 2018 and going forwards, the same video will be archived mostly for future viewers as well and not just current viewers. However, the video is so heavily compressed on an encoding level that no MadVR upscaling software and even my 4K OLED upscaling can help upscale an already pixelated video at the source level. Look at the scene of the rooftops at 8:20, the snapshot that someone took at the 00:17 mark, as well as the transformation scene at 19:47. The video looks too soft in both instances even though it was encoded at 1080p while the rooftop scene is inhabiting the weird 'netting' effect that was only seen in the DVD era days such as the DVD of Harry Potter and the Prisoner of Azkaban where the field of grass scene in the beginning will show the same netting effect not seen in actual 1080p blu-ray.
The higher the bitrate such as the other source video that I got it from was only 720p sadly. However, the high bitrate makes up for the lower resolution. Similarly, some 4K movie sources that are encoded below 20GB exhibits softer video overall with lesser details surprisingly than a 1080p Blu-ray source due to the high bitrate that I have had compared to before as well.
But this is just my personal feedback. Still love the animation subtitle effects you guys put in the video. It just blends so well with the video. And that is why I use them for archiving. But there has been no improvement of video source encoding over the years. The loss of detail will get quite noticeable as TV size gets bigger as well as resolution increases. Just my 2 cents. Hope it leads to an improvement.
Here's the comparison between the 1080p T-N source (has TV station watermark) vs a high bitrate 720p source.
Takenoko & co can talk a lot more about the capping and encoding process. But you're definitely on to something. There's a rather significant difference in image sharpness between those images.
On paper, the bitrate TV-N uses here should be adequate. It could arguably stand to be a bit higher, but with a high quality encoder (e.g. x264 in Slow mode), that should be a reasonable bitrate to work with.
My gut feeling then is that the difference is due to the source rather than the TV-N encode process. That the image was already soft before TV-N even gets it. And this gets into Japanese broadcast specifics that I'm not really familiar with; particularly why your second copy doesn't have the TV Asahi watermark. Is KR rebroadcast later on without that water mark? Or is Toei offering digital downloads? I'm very curious where that raw came from, as that would probably explain what's going on.
As for the Edo lot roof, that's not a matter of bitrate but rather it's a moire pattern. Typically it's a sign of either a bad scaler or a bad deinterlacer. The 1080p encode doesn't need scaled, so that should rule out the former and point to the latter. I'm assuming KR is being broadcast in 1080i, so it needs IVTC'd back to 24fps. But something seems like it was thrown for a loop there. In either case, if it is a deinterlacing problem, then there's a good chance the root cause can be fixed.
Overall though if these screenshots are accurate, then there's definitely room for improvement in the processing chain.
Hi. Thanks for getting back to me. Was slightly sick earlier and was finishing writing my post on separate occasions. Thus, my post may seem a bit confusing. My bad.ViRGE wrote: ↑Thu Sep 06, 2018 2:42 amAppreciated.takenoko wrote: ↑Thu Sep 06, 2018 1:41 am Appreciated.I think first and foremost we need comparable frames taken from the master recording to compare to LiLAsN's screenshots. Along with info about where LiLAsN's raw came from. That way we could at least isolate the matter to being a source problem or an encode problem.
The source footage was sourced by another fansubbing group called Over-Time that will release the 720p RAWs under the name [THISFILEHASNOSUBS] and then finish the subtitling within less than 24 hours from the RAW release. For example, the last episode of Build's RAW was released at 2018-08-26 12:10pm. On the same Sunday at 15:55pm (3-4 hours later), they released the file with their subtitles on it. So they are more of a speed subbing group which I only got to find out as I was too eager to watch the last few episodes of the series as fast as I can as it was getting too exciting.
You can find the source of the RAW and subs at Nyaa.si by just typing Kamen Rider in the search and letting the search be arranged by Date (descending order from the latest uploads)
As you can see from my pictures, the video has been upscaled by MadVR to suit a 1440p monitor resolution thus even the mp4 file that T-N uploaded may look slightly better than original (though not by much due to blurry edges and pixelation during action-heavy scenes). You can use this and compare the RAWs with the 1080i TS raws that T-N got from. But I am not surprised. If you check 1080i's pixel count, it is actually lesser than a 720p video due to how interlacing works.
As you can see from the screenshot of the gold Zi-O, they have also subbed the words written on the monument of his first Henshin which was missing from T-N's version when I rewatched it again using the T-N's video that they just released.
Oh yes! I forgot to mention, there is an episode 1.5 titled Kamen Rider Zi-O Hokan Keikaku. The source can once again be found at nyaa.si from [THISFILEHASNOSUBS] which is Over-time's RAW.
Also, I do have a .ts TV recording source that has a weird resolution of 1440x1080p. The file title is in Japanese and is 3.61 GB. At the rooftop scene, the source does exhibit the moire pattern similar to T-N's and has blurry edges. And you are right. Based on this TV recording source, the video was just as pixelated during the transformation scene due to interlacing artifacts.
