Once you have determined how your users will be viewing your video, you can use our video encoding API to apply VBR bitrate to your media files. Consider what platform your video will be viewed on prior to selecting your bitrate. As we mentioned above, internet videos, phone videos, and HD blu-ray videos for tV all vary in bitrate. When it comes to choosing what bitrate is best for your video workflow, it is important to take into account what device your videos will be played on.
WHAT IS A VIDEO CODEC HOW TO
How to choose the correct bitrate for your workflow? Winhoros Bitrate Viewer is an excellent tool for scanning your files to get detailed bitrate information:įor analyzing Blu-ray Discs, see BDInfo for Windows
MediaInfo is a nice basic tool for quickly seeing all the parameters on a video file: HD 1080p H.264 high profile 5000 kbps (35 MB/minute)īelow we recommend a few tools for detecting bitrate and codecs. HD 720p H.264 high profile 2500 kbps (20 MB/minute)
WHAT IS A VIDEO CODEC 480P
SD 480p WiFi H.264 main profile 1200 kbps (10 MB/minute) LD 360p 4G Mobile H.264 main profile 700 kbps (6 MB/minute) LD 240p 3G Mobile H.264 baseline profile 350 kbps (3 MB/minute) For example, these are the targets we usually see for H.264 streaming: The bitrate for an HD Blu-ray video is typically in the range of 20 mbps, standard-definition DVD is usually 6 mbps, high-quality web video often runs at about 2 mbps, and video for phones is typically given in the kilobits (kbps). So a data rate specification for video content that runs at 1 megabyte per second would be given as a bitrate of 8 megabits per second (8 mbps). The data rate for a video file is the bitrate. Video data rates are given in bits per second.
Finally, we show you how to use to produce CBR and VBR output.Ī video bitrate is the number of bits that are processed in a unit of time.Remember that 1 byte consists of 8 bits. First, let’s have a look at the units of measure for video encoding, and then we’ll look at the differences between Constant Bitrate (CBR) and Variable Bitrate Encoding (VBR). Another consideration is that variable bitrate (VBR) encoding will produce better image quality than constant bitrate (CBR) in most applications. At the same bitrate, video in a newer codec such as H.264 will look substantially better than an older codec like H.263. In general, a higher bitrate will accommodate higher image quality in the video output. It’s important to understand how the bitrate control corresponds to video quality and the file size.
