#AUDIO VIDEO SYNC TEST VIDEO TV#
(This may introduce a video delay instead, if your TV is doing its own processing, like motion smoothing, but you can use the lip-sync feature on your soundbar to delay the audio to match.)ĭespite being the ideal audio delay fix, I mention this last because it comes with one big downside: most soundbars don’t have many inputs. But if you plug your Roku into the soundbar, then pass video through the soundbar to the TV over HDMI, any delay caused by audio processing will disappear-because your soundbar will wait to send the video to the TV until all its work is done unpacking the audio. If your Roku is connected to your TV, which then sends audio to your soundbar over HDMI ARC or optical, you’ll have to use the above (often imperfect) solutions to mitigate the delay. The best solution, in my opinion, is to re-configure how your soundbar and TV are connected.
Plug your source into the soundbar instead of the TV Manufacturers try to fix this audio delay problem on their own, but there’s only so much they can do. Couple that with any other processing you’re doing-like motion smoothing on your TV, or “virtual surround”-type features on the soundbar-and you’re basically guaranteed out-of-sync dialogue. If the TV doesn’t know exactly how long your soundbar will take, it may send the video before the soundbar has finished, leading to a disastrous mismatch of the mouths on screen. But when you introduce another product-like a soundbar-your TV might decode the video while your soundbar decodes the audio. If you’re playing that audio on your TV’s speakers, your TV is doing all the unpacking, so it can hold off on sending both the video and audio until the process has finished. We’re talking milliseconds, usually, but time nonetheless-and higher bitrate formats (like multi-channel Dolby Atmos) might take longer than a low-bitrate stereo track, leading to a more noticeable delay. When that signal is sent to your TV or soundbar, the device has to decode the audio in order to play it over your speakers, and that process takes time.
#AUDIO VIDEO SYNC TEST VIDEO MOVIE#
The Streams recording was scheduled by a Teams operator on a different laptop.Specifically, when you watch a Blu-ray or stream a movie on Netflix, that audio is encoded in a certain format-like DTS or Dolby Digital. The Audio Teams laptop was in the same location as the 5 camera's and the VMIX Teams laptop. So our VMIX -> External -> Teams Presentation could have a little bit extra video delay in this configuration, but we did not expected that to be 3 seconds in the recording! This is just a temporary limitation, though-stay tuned for updates If you record a meeting in which someone's video is spotlighted, the video won't be spotlighted in the recording. This to overcome the problem that Streams is not working with Spotlight information, so your recording of spotlighted persons does not work. Output as confidence monitor, and share that confidence monitor as a presentation towards MS Teams. We also have Teams NDI Broadcasting enabled in the organisation, but we ended up using an External A teams operator laptop, taking care of questions and muting/unmuting during cooking, etc. A video laptop mixing the 5 x PTZ NDI camera's A cook with laptop with earphones cooking (he could hear the questions, and answer in realtime) The Audio was 3 seconds before the Video in the Streams recording. Hi did an VMIX -> Teams -> Streams recording today, and we definately had sync issues in the recording.
