![]() ![]() Let’s now jump right in and take a look at the characteristics of some popular codecs. The lower the bit rate, the lower the size of the encoded audio and the network bandwidth requirement. Most often, the bit rate is a tunable parameter during encoding.īit rate is important because it has a direct impact on the size of the encoded file (in storage applications) and the network bandwidth needed for audio transmission (in streaming and broadcast applications). Bit rate is expressed in units of kbps (kilobits per second). The bit rate of a codec refers to the (average) number of bits it uses to encode one second of raw audio. Bit RateĪ note on “bit rate” before we start. If not, do check my article on the basics of digital audio here. This article assumes that you have an understanding of the common terms related to digital audio like frequency, sampling rate, and channels. If you’ve been wondering what exactly is the difference between MP3, AAC, AC3, WAV, WMA, and Opus, then this article is for you. In particular, I will focus on the aspects that are most relevant from a user’s perspective (and not from an algorithm perspective). For example, the XDCAM EX format uses MP4 files, and the AVCHD format uses MTS files.Īls een regio wordt geselecteerd, wordt de taal en/of de content gewijzigd op this article, I will discuss and compare the key features of some popular audio codecs. Several formats associated with specific modern cameras use MPEG-4 encoding.Adobe Media Encoder can also import XDCAM HD files in MXF format. It can import the Op-Atom variety used by Panasonic cameras using the DV, DVCPRO, DVCPRO50, DVCPRO HD, and AVC-Intra codecs to record to Panasonic P2 media. Media eXchange Format (MXF) is a container format. Adobe Media Encoder can only import some kinds of data contained within MXF files.Also, Premiere Pro does not support FLV import. Adobe Media Encoder, however, can import FLV files using the On2 VP6 video codec, not the Sorenson Spark codec. FLV files generally contain video data that is encoded using the On2 VP6 or Sorenson Spark codec and audio data encoded using an MP3 audio codec. F4V files generally contain video data that is encoded using an H.264 video codec and the AAC audio codec. FLV and F4V formats are container formats that are associated with a set of video and audio formats.Video for Windows and macOS(requires QuickTime player), AVI Motion JPEG files on macOS Sony Venice V3, Sony Venice V4, Sony VENICE 2 Ver.
