What is audio / video latency (syncing audio with video)?

That's a tough one, it does not say on the box or the website. I'm not sure how to measure it either but for what it's worth, I'd say the audio/video latency is very very low or does not exist for the average joe.

If you are using this with a video player, latency is very important. If the latency is high, the sound from the speaker will be later than the video image--e.g., singer's lips moving but song audio is out of sync. For a typical movie of TV show the latency may not be very noticeable. BT speakers with the aptX codec have the lowest latency, but this seems not to have that codec. Of course if you are only playing music and not watching video, latency is irrelevant.

I am currently using this speaker setup with new LED TV and synching is excellent. No noticeable gap between audio and video.

I am assuming the bottleneck is the hard drive. My pc desktop's hard drive is 7200 rpm and there has been zero frame drops.24 MB of system memory, 7200 rpm hd, Adobe premiere. Also the hd to store vid cap was a separate drive from the OS drive. This should give you an idea even though we use different platforms.

Check your dvd player to see if it has an audio sync/delay feature. I've seen some that do to adjust for the audio/video delay via HDMI. I haven't had any audio sync issues, but I'm also using optical audio to a separate stereo.

I do sync mine via windows media player and have never had a problem. Might be defective.

It will not automatically sync the audio, however it shouln't be hard to sync in your editing software if you use slates or claps between shooting.

0 delay on video and audio OSX or Bootcamp but I noticed it runs smoother when I added 24gb of ram in my Imac.

Not sure about that I was running Mountain Lion. The issue i was having was the syncing of the audio and video.

Haven't measured it rigorously, but there's usually about a ten to 30 second delay between what you shoot live and what is seen on livestream, depending on the connection you are using - wireless or wired.

I have tried this device many times but never noticed any async audio with video. I think the delay could be caused by the codec which you used. There is a chance that your PC cannot encode video fast enough and that cause the delay.

My video constantly lags the audio, because the video comes out of our Kramer 747 video switcher-scaler, while the audio comes in directly off of the sound console for the auditorium. Is there a solution? Probably several. But what I do is simply offset (delay) the audio to match up with the video using (free) video editing software the name of which escapes me at the moment.

Are you monitoring via DAW? That will inherently cause latency because it has to go through the AD/DA converters (plus whatever latency is induced in the DAW). Its unavoidable if you need to monitor an effected signal, but if you just want to monitor the dry signal, turn up the "To Mon" knob and mute the track you are recording in your DAW. The input monitor sends it to the monitors before any AD conversion, so the latency is practically zero (i mean...its whatever time it takes to travel through the cables which is zero latency to human ears).

I perceive NO DELAY at all. The video transmission is very fast with no noticeable latency. When I attach a video camera to the RF transmitter, and a video monitor to the RF receiver, I do NOT notice any lag between the image on the video monitor and what the video camera sees. I have to say that for their low price, this RF transmitter / receiver pair provides top-notch performance and superb value.

Has anyone had any problems with audio/video being out of sync? This reviewer had problems with this on the 720 model: http://www.amazon.com/review/R3TPJCPHOD8OK8/ref=cm_cr_rdp_perm?ie=UTF8&ASIN;=B004QOA92A

I am really critical of audio and video getting out of sync. I am glad to report that in my testing, I saw no decernable sync issues on movies on my iPad.

If your video editor can make small changes in the play length of the video, you can keep the audio as it is and just stretch or shrink the video a fraction until it syncs. Nobody will notice.

I have had to set the voice sync on my Bluray player to 120 mS however, I'm running two separate HDMI paths, one for dedicated video and the other for dedicated audio so there is no path for automatic voice sync. I believe typical voice sync issues are at play in my system not video processor latency but I have never switched the DARBEE in and out to compare. However, in my research prior to purchasing I came across this article that describes some of the effects of using the DARBEE. http://www.eurogamer.net/articles/df-hardware-darbee-darblet-review. In their testing they show the latency to be 16.67 milliseconds or less than one frame. I hope this helps.

Check out the threads on avsforum.com and you should find a solution to your problem. I'm using the 705 with Cox cable box and Netflix streaming (Roku) inputs and have had NO audio sync issues but have seen some reports of them on the website I referred you to. Cheers
