Study Notes
Video Encoding Fundamentals
- The primary purpose of the latency budget in video encoding is to control the delay between the time the video is captured and the time it is displayed, ensuring real-time processing and playback.
Constant Bitrate (CBR) vs. Variable Bitrate (VBR)
- The primary difference between CBR and VBR in video encoding is that CBR maintains a consistent bitrate throughout the video, while VBR adjusts the bitrate based on the complexity of the scene, optimizing quality and file size.
Quantization Parameter
- The purpose of the quantization parameter in video encoding is to reduce the precision of the video data, allowing for efficient compression and smaller file sizes, but potentially sacrificing visual quality.
B-Frames
- The primary advantage of using B-frames in video encoding is that they enable efficient compression of video data by predicting and referencing future frames, reducing the overall bitrate and file size.
Deblocking Filter
- The purpose of the deblocking filter in video encoding is to remove visible block artifacts caused by compression, resulting in a smoother and more visually appealing video output.
Assess your understanding of video encoding concepts, including latency budget, CBR and VBR, quantization parameter, B-frames, and deblocking filter.
