This is because bitrate Bitrate is the rate at which data is sent to the encoder in your broadcasting program.
Streaming video compression artifacts 1080p#
Still have a question? Send him an e-mail! He won't tell you what TV to buy, but he might use your letter in a future article. Honestly, unless you are streaming at 1080p 30 fps, there is no way to stream without ruining the video feed with excessive compression artifacts. plasma, active versus passive 3D, and more. Got a question for Geoff? First, check out all the other articles he's written on topics like HDMI cables, LED LCD vs. A Google search of "Is Kabletown better than DirecISH TV" or whatever your providers are will certainly turn up a lot of opinions.
If your current cable or satellite provider has a lot of macroblocking or other compression artifacts, it's possible switching to the other type of TV might result in a better image.or it might not. Your best bet is to just use the highest-quality source you can, whenever possible. Reducing the sharpness control on your TV can help minimize the ugliness (and it's probably not a bad time to check your settings anyway). Many cable providers highly compress their HD signals, resulting in an image far inferior to Blu-ray or over-the-air TV, with lots of macroblocking and other compression problems.īecause this is a source issue, there's not much you can do about it. Many stations squeeze their HD channel (compressing it further) to fit other channels of digital standard-definition content.Ĭable and satellite broadcast have this issue a lot. Over-the-air broadcasts may have it, depending on how much bandwidth your local channel devotes to its main HD signal. Blu-ray Disc video, as mentioned, isn't likely to have it unless it's an artistic part of the content. Not every source will have macroblocking. Shots of the ocean are another problem, as there are a lot of individual things moving in the shot (like the wave tops).
One video file might be 480p/1050 kbps bitrate, another might be 1080p/4300 kbps bitrate, etc. They switch between them based on perceived network conditions. Furthermore, they save multiple videos with varying degrees of H.264 compression. The confetti at the end of the Superbowl was a macroblocking mess. To break it down, I believe streaming services like Youtube save videos in the H.264 compressed video format. You'll most commonly see macroblocking in fast motion, or when there's a lot going on in the image.
