I just updated my Apple TV 4K and this same thing started happening to me today. Watched two Netfix movies last night with no issues, but tonight the sound streams to my airplay Bose speakers ahead of the video. Also, my picture is slightly glitchy. When I change to TV speaker (which runs through HDMI cable) sound is perfectly synced with video and no more glitch. Again, this was NOT an issue until my Apple TV updated. This doesn't look like a fluke. It looks like a BAD UPGRADE. PLEASE FIX ASAP!
I am having the same issues with the NEW Apple TV. lagging after watching for a few minutes, however, may lagging occurs on YouTube TV and other apps. I have been a big supporter of Apple TV but if this lagging is not corrected I will have to change hardware, which is a lot since I have two homes. What is Apple doing to try and fix this problem?
This is happening across all of the live streaming apps. Please investigate the root cause. This is absolutely repeatable. This makes it difficult to recommend Apple TV as a streaming device for anything but prerecorded material. I am available to assist in any troubleshooting.
Apps are engineered for the devices where they're downloaded, so you may have different settings or performance for each. For example, the Netflix app may work differently when downloaded directly on your Smart TV than it does when downloaded on your Apple TV, or it may require various settings to be customized to optimize performance through that device.
Watching ESPN last night during the baseball game the sync was so off the on camera was unwatchable. I have a high speed cable and running sound via hdmi . Watching Amazon prime or Netflix no problem but streaming ESPN was horrible.
I have the same issue but only if I use airplay to direct the audio to my speakers. However, if the audio is transmitted through bluetooth, then I get perfect synchrony. This problem only happened after my Apple tv HD had it last update on September 20, 2021.
To get very specific, shows like Star Trek DS9 (Netflix) and John Oliver (HBO) go out is sync almost immediately. Any live streaming app also. Newer shows and movies go out of sync less frequently. I have no problems with streaming directly through the TV (LG CX). I think this is my last apple TV.
LOL I was just thinking about that today. I don't recall what all the defaults are, and the ones I have flipped I haven't really 'tested' them, so I can't say. And then you have all the different scenarios with different media where it may or may not affect your experience.
Every digital audio is PCM, from the basics, but encoded differently. One of its encodings approach is Dolby Audio, this having reference audio levels (volumes) for home theater listening, which is a quite old standard nowadays albeit used. They scope 85dB average, 105dB peaks in any satellite speakers (front left/right, central, side left/right, surround left/right). This setting will set any and every digital audio source (PCM) being passed through (or decoded) and level it to Dolby reference. It can help improve the dynamic range by using a standard. Netflix content has narrow reference levels and by matching Dolby it gets closer to the dynamic range of it, for example.
You might be familiar with the high-resolution audio term or going through Windows Audio Settings and seeing CD-quality, DVD-quality, and Studio-quality as audio quality options. As an industry standard, CD is the equivalent of 44.1kHz at 16-bit PCM audio, while DVD is commonly 48kHz at 24-bit, and Studio is 96kHz - 192kHz at 24-bit. It illustrates how many times per second it can sample (x times 1000 Hz) and how much data it can hold (216 or 224 different numbers representing data per sample). High-res audio starts beyond 44.1kHz at 16-bit and the term is normally used for 96/24 or 192/24.
I have both enabled. I'm running the Shield in an LG CX and a Samsung Q950A and both support the most common high-res lossless audio formats, although the TV only via passthrough since by itself it caps at 44/16. I passthrough all the data digitally through the TV to the soundbar that, then, decodes it and converts to analog.
La plupart du temps ce que tu entends et ce que tu peux lire dans les sous-titres veut dire la mme chose.Comme @jilliagre l'a dit, cela peut tre fait pour que ces sous-titres soient plus rapides lire, et que le public puisse plus se concentrer sur la srie.
The dubbing don't only have to translate the meaning : it also has to match the movements of the lips and sound right with the scene. For this reason it can sometimes require to get rid of the exact meaning to find something that both makes sense and looks right.
I have been bothered by this phenomenon as well, and I don't claim to know the answer. However, my theory is that while the audio is written and performed one way, the subtitles are simply machine translated from the original English. My guess is that it is a cost-saving measure. (If someone wants to prove or disprove that theory, I don't mind being corrected.)
Whatever the reason for the difference, I do hope that at some time in the future the subtitles can be made to match up to the dialog. I am also trying to learn French from Netflix, and it would be most helpful if I could read what was actually spoken.
Audio must be recorded in sync to picture at native project frame rate. All audio deliverables should match the camera and picture post production frame rate. All audio must sync to the final IMF/Prores picture delivery. Alternate/Dubbed Language and Audio Description Mixes must not contain an additional leader. Printmasters, M&Es and stems may include standard 8 second Academy leader and 2-pops.
Content Hub deliveries may be discreet audio files alone, within folders or within Pro Tools session folders also containing sessions. Where project files other than Pro Tools are delivered, AAFs/OMFs should also be included, or all channels must be rendered to continuous PCM audio.
Note: The resulting 2.0 mix must be checked prior to delivery to ensure it is free of any audio artifacts and if necessary, as determined by Netflix, further adjustments shall be made to prevent them. Any 2.0 delivery must meet the specification prescribed in this section.
NOTE: The below are not Technical Specifications. The below is guidance to help achieve an optimal customer experience. Following the guidelines below is not required by Netflix, but is preferred.
We recommend setting a True Peak limiter at -2.3 for all audio deliverables. For 5.1 / 2.0, this helps to prevent false positives from minor differences in metering. For Atmos beds and objects, this setting will reduce excessive peaks due to summing factors within the Atmos renderer.
We recommend near field mixing in rooms that approximate the size of a living room. Larger or smaller rooms can also work, when they are well-built and aligned. Use multiple microphones near the mix position which average to align rooms. Atmos rooms should be 7.1.4 at a minimum, but 9.1.6 is optimal. We suggest a moderate or light X-Curve for near field, rather than the standard cinema curve. Dolby engineers are available to assist with alignment for facilities that would like it.
