The AV-sync delay increases with distance. During mixing of video clips normally either the audio or video needs to be delayed so they are synchronized. The AV-sync delay is static but can vary with the individual clip. Video editing effects can delay video causing it to lag the audio.
Latency refers to a short period of delay (usually measured in milliseconds) between when an audio signal enters a system, and when it emerges.Potential contributors to latency in an audio system include analog-to-digital conversion, buffering, digital signal processing, transmission time, digital-to-analog conversion, and the speed of sound in the transmission medium.
Analog audio video (AV) equipment historically used one-way, single-purpose, point-to-point connections. Even digital AV standards, such as S/PDIF for audio and the serial digital interface (SDI) for video, retain these properties. This connection model results in large masses of cables, especially in professional applications and high-end audio.
All video streamers have to deal with it. To help smooth out, speed up, and minimize your video streaming issues, here are a few tried and tested tips. How to reduce lag while livestreaming video
Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag, as it is known in gaming circles, refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games. [1]
Whether it's a buffering video or a stuttering internet video game, we all know the bane of online existence that is lag.You especially know how annoying lag is if you livestream.If you broadcast ...
Unfortunately, video delays frequently make quick and large changes, for example, a jump in delay time from 2 seconds to 6 seconds is possible. To maintain proper audio-video sync, the audio delay must track these video delay changes. Changing the audio delay requires changing the difference between the write address and the read address.
Lag is mostly meassured in milliseconds (ms) and may be displayed in-game (sometimes called a lagometer). [1] The most common causes of lag are expressed as ping time (or simply ping) and the frame rate (fps). Generally a lag below 100 ms (10 hz or fps) is considered to be necessary for playability.
