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!

Yes! Finally a REAL and accurate sync/delay demo. Used the on board app and on the external devices and synced perfectly in passthrough and auto. Thank you so much!

[@AudioAdvice]

Great to hear!

Thankyou...is this setting on all AV recievers? This is interesting because my blueray is out of sync with my reciever.

Happy to help, yes if your AVR has a lip sync setting.

[@AudioAdvice]

@@sj460162 make sure your Blu-ray is outputting bitstream and not PCM. If your receiver does not have lip sync you may not be able to fix it. Also you should be wired BR to receiver, receiver to video display

Sir ,i think finally i reached a place which i was looking for.Hope you can help me out with a query.My amplifier is denon 4700h. When ever i play any video, let it be in hard disk, apple tv, netflix, youtube, its moving a bit fast.In all my source its playing like that. What should i do to play it like in normal speed

[@AudioAdvice]

If you are saying the video is ahead of the audio, that is very strange, it is usually the other way around. Make sure all of your settings are for bitstream or Dolby output on your streaming devices

i'm using my laptop. and i'm using thimeo stereo tool as real time sound enhancer audio interface with that program running i'm getting a delay of approximately half second. (+500ms). is there any browser extention that sets a negative delay in order to compensate the delay generated by the program i'm using?

Not that we know of, but we are not versed on all of the computer DIY tools. Thanks for watching

[@keithb4077]

What's the issue if I don't have lag from KZbin, DVDs, or Netflix, but I do have lag from Prime and 4K discs? The source is all the same: a Sony 4k player, running through a Denon receiver, then video out a to a Sony TV (and of course, direct audio to speakers from receiver). Thanks a million.

[@AudioAdvice]

Yes we see that sometimes. There are a few AVRs that let you adjust lip sync in presets. HBO Max also does this in some systems. Unfortunately you will need to adjust for each source or you may try connecting you BR player to your TV and using its eARC output if you have that.

[@BluegrassMike]

Ugh, very confused haha. If I try to watch/listen to the test video, then bring up my settings menu on the tv, it covers the middle part of the video where you can't see the line. So how are you able to watch/iisten to the video then adjust the delay setting if can't see/listen at the same time?

[@AudioAdvice]

Hi there, check out this page where you can download the lip sync video: www.audioadvice.com/videos-reviews/how-to-set-lip-sync-calibration-home-theater You may have better luck playing it as an mp4 file rather than on KZbin.

[@vpnogueira]

If I don’t use an audio/video receiver and connect directly the digital audio out of the HDMI switch to my stereo audio system, and the video to a projector, what is the simplest/best way to adjust the delay/lipsinc?

[@AudioAdvice]

There is not a way unless any of our sources have audio delay capabilities. Thanks for watching

[@TalkCafe]

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.

[@RuudZeelenberg]

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.

[@AudioAdvice]

It should be spot on, we will double check

[@AudioAdvice]

We double checked it and it is spot on, you do need to be at 60 fps. It is possible YT is doing something in their compression Here is a link to the original file for you to use, many people requested this so they could burn it to Bluray testing audioadvice.com/pub/media/videos/audio-advice-lip-sync-calibration.mp4

Audio latency

[@amytong6318]

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? ",

[@AudioAdvice]

Great question. Yes, anything that plays digital music has a DAC built in. In the world of DAC's, there is a wide range of quality. Your computer for instance has a DAC but its normally pretty bad. Sending the digital signal out of your computer will bypass its DAC and allow you to pass it through a better DAC. For your speaker question, it depends on how you wire things. If you ran a digital signal into an amp with a DAC, that would be the final DAC. But you could have a better separate DAC that you ran with analog audio cables into your amp and in that case, the DAC in the amp would be bypassed. Hope this helps

[@amytong6318]

@@AudioAdvice Great clear explanation, now it make sense to me, cheers

[@truwarrior22]

Strange, does not work when I use eARC to my Arcam AV40, it’s like the signal is going in and out.

[@davidclarke1152]

Am I the only one; Where do you get this "Test Screen" ? Have never seen this on any of my 3 Samsung TV's Or either of my 2 Sonos Sound systems. Sounds interesting & might work but you neglect to say how you get started. I'm convinced it's a Samsung issue not from any of the streaming apps or Sonos sound systems.

[@AudioAdvice]

This is for lip sync and would be used if you had a soundbar or audio system with separate components. The TV would just display the video. Most of the Sonos soundbars do have a lip sync adjustment setting in the app. Thanks for watching

[@stephencostello8792]

So clever

[@AudioAdvice]

Thanks!

[@bigikes4137]

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

[@AudioAdvice]

This test only works for streaming sources like Apple TV, Roku, Firestick, etc. But you make a great point, we spent a lot of time trying to come up with a way to make it easy see how to adjust. We will look and see if we can provide a file that could be ripped to disc for use with a disc player, as they too have varying delays.

[@Koozwad]

Correct me if I'm wrong but, this is so much better to do when putting at 0.25x speed.

Correct! Great idea!

[@Koozwad]

@@AudioAdvice The problem with this method is that sounds used in videos like this are too long(they start early before the marker is in the centre). It would be ideal to have as short as possible a beep, and then being able to slow it down a LOT for that ultimate precision.

My audio is still late even after taking the delay all the way down. My receiver is Bluetooth to my TV. PCM already set too

The bluetooth is the issue. Can you not connect an HDMI cable from the AVR to the TV?

@@AudioAdvice Just an heads up, indeed...the test from this video is flawed, its around 50-100ms off, i checked this file in final cut pro, you might have run to a know bug in apple compressor with HEVC when making this video (there is / was a known bug that caused video / audio out of sync of some frames).

Sadly no Dolby surround sound so can’t test my satellite Bluetooth speakers

[@AudioAdvice]

Lip sync applies to the center channel speaker.

[@BaronVonGreenback1882]

I have no idea what the hell you are talking about

[@AudioAdvice]

This occurs when the voices you hear do not line up with the movement of the persons lips on screen, that is why it is called lip sync. Some devices create a video delay which can put the audio ahead of the video you see, this is a good method to use to correct for it. Most modern AV gear has a lip sync adjustment function.

[@BaronVonGreenback1882]

@@AudioAdvice I see, my sound bar is out of sync with my projector but the projector doesn't have any sound adjustment options, any idea how I fix ?

[@goanna300]

I can't make sense of what he's saying.

[@AudioAdvice]

This video is to help you calibrate the lip sync function on a home theater receiver or soundbar (if it has the adjustment). In some cases the audio will be ahead of the video and this will help you line them up.
