Synopsis:
When Kazuma Satou died, he was given two choices: pass on to heaven or be revived in a fantasy world. After choosing the new world, the goddess Aqua tasked him with defeating the Demon King, and let him choose any weapon to aid him. Unfortunately, Kazuma chose to bring Aqua herself and has regretted the decision ever since then.
Not only is he stuck with a useless deity turned party archpriest, the pair also has to make enough money for living expenses. To add to their problems, their group continued to grow as more problematic adventurers joined their ranks. Their token spellcaster, Megumin, is an explosion magic specialist who can only cast one spell once per day and refuses to learn anything else. There is also their stalwart crusader, Lalatina “Darkness” Dustiness Ford, a helpless masochist who makes Kazuma look pure in comparison.
Kono Subarashii Sekai ni Shukufuku wo! 2 continues to follow Kazuma and the rest of his party through countless more adventures as they struggle to earn money and have to deal with one another’s problematic personalities. However, things rarely go as planned, and they are often sidetracked by their own idiotic tendencies.

Unfortunate non-transparent audio bitrate, contrasting the high quality of the video.
Thanks for the AV1 encode.

Thanks again for the encode!

I think 96kbps opus is mostly okay if you compares it to 128kbps. I do not think their difference is huge -> they are all mediocre. Personally I would feel better if the bit rate is bumped to 160kbps or even 192.

Oh good! Seems this latest work has video encoded in 2 tiles!
You mentioned CRF26, which encoder you are using, I mean
ffmpeg libaom-av1
oraomenc
?Again, thank you for your efforts!

@hotaru39 ffmpeg libaom-av1, some of us use aomenc but video piping causes some performance loss for the same quality.
Yeah, after a lot of researching and testing, we determined that using to 2 columns (not rows) offers the best performance to efficiency loss (around 1%).
If you are interested in AV1 codec, I can recommend visiting this subreddit https://www.reddit.com/r/AV1/

@Montec Okay I see… I’m already a old member in that subreddit haha! Glad to see people also interested in this fancy codec! I was researching AV1 since its first release, however the deployment of AV1 in real world seemed to be a little bit too slow, might due to Google’s “light speed” encoder. I hoped Xiph.org’s rav1e could be a new star, but currently it seems that aomenc is outperforming it.
Youtube initially also used two tiles in their video(see their AV1 beta playlist), but changed to 8 tiles someday, I think it should be a trade-off for decoding performance. A video that could not be decoded properly is just useless 0 and 1 s.

Oh by the way, which speed you are currently using? Probably
--cpu-used=0
I guess… ^_^Montec (uploader)
@hotaru39 After further testing with cpu speeds we settled with cpu 3. This was done quite a long time ago, and things could have changed, but at that time cpu 3 was twice as fast as cpu 2 and the efficiency improvements were very minor after that point (4% improvement for cpu 0 but orders of magnitude slower). Btw there is a Discord channel, I’d highly recommend joining it, there we develop tools for encoding and discuss latest test results. Invitation should be on the front page.

I’m sure that, however small you think this audio quality difference is, it is smaller than the difference in video quality if those 32kbit/s were removed from the video track and given to the audio track.
And the audio would be 128kbit, as recommended by xiph for transparency, to boot.

This is my first AV1 encoded anime I downloaded, but I’m disappointed. The image quality is subpart compared to similar sized HEVC. Every frame I checked was blurry and the lines were thicker than they should’ve been.
