HOW TO UPLOAD TO YOUTUBE WITH HIGH QUALITY SOUND<\/p>\n
Basically YouTube uses “H.264 AAC-LC” or “Opus” as the audio codec.
\nThe video codec used is “H.264” (MP4) or “VP9” (WebM). “AV1” is also used in some videos.<\/p>\n
Verification method
\n(Video) Download the official video of “3D Youtube Downloader”, upload the video to “VLC Media Player” and refer to Media Information \u2192 Input Bit Rate in Statistics.
\n(Audio) Check the audio of the video downloaded by the above method using “foobar2000” for the bit rate. The cutoff frequency is converted to .wav format by “XMedia Recode”, and the file is imported into “WaveSpectra” and verified.<\/p>\n
\u25cf PC
\nThe PC version of YouTube ranges from 144p (320 x 180) to 4K (3860 x 2160), but there are differences in the image quality that can be selected and the audio that can be played depending on the browser.
\nYou can check if your browser supports it on the next page.
\nYOUTUBE SUPPORT BROWSER<\/p>\n
The following is the support status for each browser (browsers that support both VP9 and MP4 have the highest picture and sound quality).<\/p>\n

\n[Caution] In the following table, only those whose use is currently confirmed are listed. Therefore, not all configurations are listed.<\/p>\n
Photography
\nSince the video bit rate is a variable bit rate (VBR), the upper and lower limits are listed. The mean value is somewhere in the middle.<\/p>\n
