\nVideo format: AV1
\nAV1 is an open source video compression format called AOMedia Video 1. Since it is a codec in development as a successor standard to VP9, \u200b\u200bit seems that VP9 videos will eventually be replaced by AV1, but it will take time to replace them because the only supported browsers currently are Chrome and Firefox. .<\/p>\n

Postscript 2020\/4\/23: Confirmed to apply to some videos.
\nWhen applied, the DASH value will be as follows
\nav01.0.05M.08 (398) \/ opus (251)<\/p>\n

DASH value Video size Video bitrate Comments
\n394 144p (256 \u00d7 144) is not clear Validated in Firefox
\n395 240p (426 \u00d7 240) is not clear Validated in Firefox

\n571 4320p (7680 \u00d7 4320) is not clear Validated in Firefox
\nAudio
\nAudio format: AAC-LC
\nDASH value Audio bit rate Cutoff frequency Comments
\n36 not clear not clear Can’t verify because iPhone 7 has no headphone output
\n18 96 Kbps 15 kHz Validated with Internet Explorer 11 on Windows 10
\nTwenty-two 128 Kbps 15.8 kHz Validated with Internet Explorer 11 on Windows 10
\n139 96 Kbps 15 kHz Validated with Internet Explorer 11 on Windows 10
\n140 128 Kbps 15.8 kHz Validated with Internet Explorer 11 on Windows 10
\nSame for AAC = 139 (96 Kbps) 18<\/p>\n

Same for AAC = 140 (128 Kbps) 22<\/p>\n

Audio format: Opus
\nSince the Opus audio bit rate is a variable bit rate (VBR), the average value is displayed. It will increase up to about 2 times.<\/p>\n

DASH value Audio bit rate Cutoff frequency Comments
\n249 48 Kbps (VBR) 20 kHz Validated in Firefox
\n250 64 Kbps (VBR) 20 kHz Validated in Firefox
\n251 128 Kbps (VBR) 20 kHz Validated in Firefox
\nOpus = 249 (48 Kbps)<\/p>\n

Opus = 250 (64 Kbps)<\/p>\n

Opus = 251 (128 Kbps)<\/p>\n

Postscript 2020\/2\/11: It looks like Opus audio was finally created for all users’ videos.<\/p>\n

Please refer to the article linked above for how to upload in high quality.<\/p>\n

To check after upload, right click on the video about a day after upload, click “Detailed Statistics” and check the value of “Codecs”.
\nAt this time, be sure to use a browser other than “Safari”. Safari is not compatible with Opus.<\/p>\n

Success story: Codecs vp09.00.51.08.01.01.01.01 (243) \/ opus (251)
\nFailure example: Codecs avc1.4d401e (134) \/mp4a.40.2 (140)
\nThe video \/ audio codecs are listed in order. (In this case, the video is vp9 (243), so it is 360p in WebM format, and the audio is Opus (251), so it is 128Kbps video in Opus format.)<\/p>\n

Depending on the video, more than 30 videos can be generated in one video.<\/p>\n

\u25cf YouTube app
\nClick here to download the app
\nANDROID IOS<\/p>\n

Version \u201c15.20.33\u201d or later updated on May 14,
\n2020 (strictly speaking, it will apply approximately from May 23, 2020)<\/p>\n

Now it is compatible with Opus audio. (Android compatible devices only)<\/p>\n","protected":false},"excerpt":{"rendered":"
