Bluetooth latency demo

[@youknowit5mil]

Your 200ms latwncy actually matched my headphones perfectly and it all syncronized

[@zlonewolf]

So thats the solution to latency. They should have software on computers that detect bluetooth or aptx latency and tells the computer to sync the video or music you're playing to 200ms slower for bluetooth or in aptx case by 30-100 ms. I dont know why there's no such thing already. It could easily be a driver or software and someone could make money selling it.

There is a very common bug with lots of Bluetooth devices (especially ones that use the Apple chipset from like 6 years ago). If you simply pause the video for 60 seconds, then click play (do not disconnect or turn anything off) it should resync itself for the rest of the session.

[@ShawnJonesHellion]

@@unknownuser8454 you need the sound the second you hit a string. worrying about this for movie snobs is just childs play. we are doing actual work an it requires precision. we arent hoping to see dora the explora or santa clause spew vomit out her mouth at the same time her mouth opens an no earlier or later. im here because i have unoticable lag in videos but when i hit a guitar string it sounds right after an is near impossible to play synced to a band an just pisses me off.. oh and to answer the original statement. you wont see lag you can still feel when hitting a guitar string. 15ms sounds like we are borderlining unplayable cause double that is bad. watchign this video has nothing on watching this video if you were hitting that piece of wood an it taking time to sound out after. he himself would probably be out of time with the tap tap tap if the lag wasnt later added in post production

[@AlexParallaX]

It is great video. You are a talented teacher. Everything is very clear and with good jokes. I watched your video with wired headphones. The effect of lagging sound is also clear on the built-in speaker in the gadget. Thank You. 👍

[@keithduffield5239]

Great thank you. Just a point. When knocking those pieces of bonking wood - it wood (or is that would) be better if you didn't do it in a repetitive manner as we cant associate which clonk belongs to which bonk. So bonk - wait one second - bonk - wait a different length of time - bonk - wait yet another different time - -- you get my drift.

[@lolindirlinkll9039]

thanks, this worked better than the metronome kind of video's! :D

[@prashantthankey9063]

When you strike that thing to produce the sound, the time gap between two successive strikes should be kept far more than the worst case audio latency. In other words, the time gap should be atleast 1 second. This will help the viewers to judge better. Otherwise, it may happen that the first strike appears to be mute, and the second strike's sound comes nearby the visual frame of the third strike, and so on. I hope you get my point.

[@watermelun6894]

I came to the comments to say this same thing. Due to my current delay this exact thing occurred

[@mja2239]

The last one was in sync for me, only that the first tap was mute and the last tap sound came from nowhere.

[@jeseefcm]

Wow superb demonstration..... the best of the best in the youtube explaining audio video sync so perfectly

[@tuyetnhungnguyenthi8871]

Latency: 0 milliseconds: Live audio & video. 33 milliseconds: Audio happens faster. 100 milliseconds: Audio happens normally. 200 milliseconds: Audio happens slower. 300 milliseconds: Audio seems to be out of sync.

[@DescartesRenegade]

Wrong on live audio and video. Light travels much faster than sound. There is absolutely latency, your brain just can't perceive it at short distances. Ever seen a baseball get hit from afar? Latency like a mofo.

[@meepcheep314]

I am happy he didn't delay the voice to the video on purpose as a joke

[@maksat.menligulyyev]

For me, as I use bluetooth headphones, it already has a latency but I cannot know (yet) how to measure that. So, I thought it would be very nice for those who want to check the latency to do kind of "reversed latency" (that is, "earlency") so we can see directly by listening on our BT ear or headphones that the sound and the image is synchronised so we would be able to say e.g. "I have a 33 ms of latency". Thanks.

[@billdownes8782]

Very good demo. I guess I was looking for the solution.

[@sin15tar]

A video for sync testing purposes should be filmed at 60 fps at least. This one is 23.976 fps (~42 ms per frame) so it lacks clarity. Thank you anyway. )

[@MikkoRantalainen]

Nice demo! I'd have preferred more light for the recording so there would be less motion blur. In addition, for the 0 ms latency you kept the stick touching the instrument after the hit which makes it easier to notice the correct timing. For the final test you hit quite hard and the stick bounced so much that it's impossible to see the the exact hit time in the video due motion blur. Dropping a metal ball on hard surface would make even a better test target for the audio/video sync.

[@MLL65]

[@tutacat]

Actually, the standard bluetooth codec is SBC, not aptX

[@Dorraj]

Honestly watching this on my desktop with headphones I can't really tell too much of a difference. However when using my bluetooth headphones with youtube, before it syncs itself, I notice it being significantly worse than even the 300ms here, especially if using any other app other than youtube that doesn't sync itself.

[@gg_0nr941]

I have 30 dollar Bluetooth headphones and it aced the test

[@GregConquest]

VLC Media Player in Windows, Mac, and Linux has hotkeys (F and G, by default, I think) that increase or decrease the Audio Delay in 50ms increments, including going negative (-50ms means the audio signal is sent 50ms before the accompanying video). So, using some high latency Bluetooth system while playing videos with VLC is no problem. I don't see how to address this problem with other apps, though. It would seem simple for any device with a built-in microphone (phones, tablets, and laptops) to occasionally send out an audio ping and internally adjust audio delay automatically to compensate. Yet I do sometimes see that youtube videos are out of sync when using a Bluetooth speaker, and there's apparently nothing I can do about it. Why hasn't this issue been addressed?

[@miagi1337]

But the Picture also has a Latency. When I look for a Monitor Review I really care for the Input Lag of the device. It is not easy to measure absolute but at least comparable. Non-Gaming-Monitors can have up to 60 ms of Input lag, 20-40 ms is what you can expect on a 60 Hz Office-Monitor (less Delay on the top of the picture, more on the bottom). So if you have a quick wireless connection it can be easily perfectly sync with the picture.
