The first iteration of Ambience Synesthesia in 2021 was held at the Shanghai World Expo Exhibition and Convention Center in May 2 and 3; as such, the concert is only easily accessible to CN server players native to China. It was first teased during the CN server's 1.5th anniversary in November 2020.  Record is split into two parts as bilibili did so, and HDR quality is only available on web client though watermark is on it (sources from TV client have no watermark, but no HDR quality is provided as my view). ```Mediainfo General Complete name : 明日方舟音律联觉专场演出 2021\音律联觉官方录播上半场.mp4 Format : MPEG-4 Format profile : Base Media Codec ID : isom (isom/iso2/mp41) File size : 2.97 GiB Duration : 52 min 44 s Overall bit rate : 8 073 kb/s Movie name : 音律联觉官方录播上半场 Album : 明日方舟音律联觉专场演出 2021 Description : 明日方舟音律联觉专场演出是由上海鹰角网络和塞壬唱片联合主办的一场以《明日方舟》音乐内容为主题的大型线下演出活动，于2021年5月2日-5月3日在世博展览馆一号馆举办。演出的音乐包含有《明日方舟》的游戏音乐以及角色EP。现场邀请到了国内一线的乐队、音乐家、歌手和演奏者们共同参演。 Writing application : Lavf59.27.100 Cover : Yes Video ID : 1 Format : HEVC Format/Info : High Efficiency Video Coding Format profile : Main [email protected]@Main HDR format : SMPTE ST 2086, HDR10 compatible Codec ID : hev1 Codec ID/Info : High Efficiency Video Coding Duration : 52 min 44 s Bit rate : 7 736 kb/s Width : 3 840 pixels Height : 2 160 pixels Display aspect ratio : 16:9 Frame rate mode : Variable Frame rate : 60.000 FPS Minimum frame rate : 58.824 FPS Maximum frame rate : 62.500 FPS Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 10 bits Bits/(Pixel*Frame) : 0.016 Stream size : 2.85 GiB (96%) Color range : Limited Color primaries : BT.2020 Transfer characteristics : PQ Matrix coefficients : BT.2020 non-constant Mastering display color primaries : BT.2020 Mastering display luminance : min: 0.0001 cd/m2, max: 1000 cd/m2 Codec configuration box : hvcC Audio ID : 2 Format : AAC LC Format/Info : Advanced Audio Codec Low Complexity Codec ID : mp4a-40-2 Duration : 52 min 44 s Bit rate mode : Constant Bit rate : 320 kb/s Channel(s) : 2 channels Channel layout : L R Sampling rate : 48.0 kHz Frame rate : 46.875 FPS (1024 SPF) Compression mode : Lossy Stream size : 121 MiB (4%) Default : Yes Alternate group : 1 ```
