When recording gameplay videos and putting them on the Internet, the bit rate used to suppress the video depends on the end use.<\/p>\n
<\/p>\n
Generally speaking, when uploading to online video website, it is recommended that the video be encoded by H264\/X264, the video bit rate should be 1600Kbps; audio must be AAC encoded and audio bitrate must be 128 Kbps.<\/p>\n
If you plan to put it on the network drive and share it with friends, it is recommended to use a higher bit rate. For example, the video is encoded by H264\/X264 and the video bit rate is 2400Kbps; the audio is AAC encoded and the audio bitrate is 128 Kbps.<\/p>\n
What does audio bitrate mean?<\/p>\n
The bit rate is the number of data bits transmitted per unit of time during data transmission, generally the unit we use is kbps, that is, kilobits per second.
\nThe popular understanding is the sampling rate. The higher the sample rate per unit of time, the higher the precision and the processed file will be closer to the original file, but the file size is proportional to the sample rate, so almost all encoding formats are used. attach. The importance of This is how to use the lowest code rate to achieve the least distortion. The cbr (fixed code rate) and vbr (variable code rate) derived from this core are all items in this regard, but things are not absolute, In terms of audio, the higher the bit rate, the lower the compressed ratio, the smaller the sound quality loss and the closer it is to the sound quality of the audio source.
\nBasically, the sound quality of the two data 44.1 and 128 in the MP3 song attribute is very good.<\/p>\n
Are higher audio bitrates better?<\/p>\n
Encoding rate (Kbps)*total song length (seconds)\/8=file size (KB), if divided by 1024, is the size in MB.
\nMP3 is lossy compression, the smaller the file, the higher the loss. The relationship between bitrate and audio and video compression is simply that the higher the bitrate, the better the audio quality and video, but larger is the encoded file; yes The opposite is true for lower bitrates.
\nBit rate refers to the sampling rate for converting digital sound from analog to digital format. The higher the sampling rate, the better the quality of the restored sound.
\nThe bitrate value is compared to the actual audio:
\n16 Kbps = phone sound quality
\n24 Kbps = improve phone sound quality, shortwave transmission, longwave transmission, European standard medium wave transmission
\n40 Kbps = American standard medium wave transmission 56 Kbps
\n= voice
\n64 Kbps = voice boost (best bit for mobile phone ringtones) = tape (best setting for mobile phone stereo MP3 player, best setting for low-end MP3 player
\n112 Kbps = FM stereo transmission FM 128 Kbps ) 160 Kbps = HIFI HIFI (best setting for mid-range MP3 player to high-end MP3 players) 192 Kbps=CD (best setting for high-end MP3 player high ) 256 Kbps= Studio Music Studio (for music enthusiasts) In fact, with the advancement of technology, bit rates are also getting higher and higher, with MP3 having a maximum bit rate of 320 Kbps, but some formats can achieve higher bit rates and superior sound quality. For example, the emerging APE audio format can provide true audiophile-level lossless sound quality and smaller volume than WAV format, and its bit rate is typically 550kbps.<\/p>\n","protected":false},"excerpt":{"rendered":"
