How To Perfectly Set Lip Sync Calibration In Your Home Theater

How To Perfectly Set Lip Sync Calibration In Your Home Theater

This video is designed so you can perfectly set lip sync in your home theater. In this video, you will see a bar moving across a timeline and you should hear a beep every time the bar crosses the zero mark. If you hear the beep before the bar crosses, then you will increase your delay in your home theater receiver.

This video is part of our Home Theater Design Series that covers virtually everything you need to know about designing a home theater. Certain flaws in your home theater setup are bound to take you out of the moment — flaws just too annoying to ignore. Having your audio out of sync with the video is certainly one of them! At Audio Advice, we are huge fans of immersive home theater. We love getting in new gear to test, and if it meets or exceeds our standards, we really enjoy writing an article then doing a video on it. Over the years, we have had thousands of people tell us how much enjoyment they derived from putting in a great home theater. It really is a great way for families to get together and forget about the world for a while.

    Thanks for this tool!
    I would add to the "how to" to play this on all of the resolutions and framerates you would use in your setup.
    On my LG OLED A1 I've exparienced that resolution has a slight or no effect on delay, but framerate change can cause hundreds of milliseconds of difference.
    For example 4K TVs usually default to 60Hz, they are the fastest on that, so with 60fps content the delay will be minimal or not even noticable. But if your TV don't have native 24Hz support (most of them does not), then to display that content the electronics have to work a lot, and therefore introduce more delay in the signal.
    The next problem is that DVDs and blurays have different default framerate, so movies stored on them will have different framesrates too. So you have to change delay settings depending on the media. Now this is the most annoying and the only solution I found is if you BD player support it, switch the output to constant 24Hz (and throw away the other 6-36 frames per second your not-bluray disc has) or use different player devices for different media and set each setting individually.
    Human perception usually can only notice 20-40ms differences between visual and audio, that's why most devices only let you set lip sync in these increments. Somehow I'm able to perceive as low as 1-2ms of difference, really annoying, you can imagine. So I've tried lots of methods to eliminate delay.
    Every AVR I saw has this "auto lip sync" feature, which would solve all our problems….
    But absolutely no TVs which will send this signal to the AVR (idk about projectors, but I guess they won't either) so the function is useless.

    Hi, thanks for these great videos.
    I have a question though, when putting this sync video in Premiere, the audio is 4 frames late (off) in comparison with the video hitting the 0 line.
    Any reason for this, am I doing something wrong (Sorry to have ripped your video through 4K downloader for checking purposes) or is… your audio / video sync just off?

    Love to hear. Thanks again for all the great info you share.

    Hi, nothing to do this this video, but can't find any answer on the web, thought this may be a good place to get the answer, the question is " Why do amplifiers include DAC when all audio players ( the source ) already include a built-in DAC ( also which DAC ( DAC from Amp. or DAC from Audip player) will the speaker choose as the final out-put? ",

    How would I use this on a 4K disc player?

    I have tried adjusting this in the past by just watching regular video, and for whatever reason, I found doing it that way to be difficult. This test pattern makes it a no-brainer!
