Facebook Video Download Audio Out Of Sync

When applying the ffmpeg encoding command on the attached video, it plays fine on a local device - the issue however is when uploading to Facebook/WhatsApp the audio/video becomes out of sync
Are the audio and video "in sync" when you use the built in camera and microphone in your laptop? In most laptops, they are out of sync by a hair. Do not blame the EOS Webcam Utility for not correcting a pre-existing flaw.
The USB approach definately is a challenge as i often feel like i have to get the planets in alignement so that Zoom (or the EOS utility for that matter) actually sees the camera. Then when it does get seen the sync is awful.
I then went with a cheap HDMI capture card and that did make the sync better it wasnt perfect and the 80D also doesnt offer 'clean HDMI'. Now you can tweak the display to turn off all overlays except the autofocus square. So for that we have to use manual focus!!! I am the other side of the lens why do i need that square?
Well i decided to go to a much higher end capture card (arrives in 2 days), if that solves the sync problem all good. If it doesnt, i guess the refund of the capture card will go along way to another camera which i hate the idea of doing because it opens the door for something other than Canon.
Our ticket was resolved. Took a few months for a resolution but I can confidently say we are no longer running into this issue with our continuous audience sync. For us, the error seemed to be related to the number of calls Marketo was making to google audiences. If this isn't resolved for you I suggest submitting a support ticket. Might take a little while for resolution but at least there is a light at the end of the tunnel!
I'm confused how to be on Zoom and Facebook Live, as I received audio feedback. Zoom is not clear - you have to have the Facebook browser open for this to work? And if so, the sound is on, and it's impossible to stream? One the livestream starts, can you log OUT of Facebook?
1. A 20 sec delay for live stream is normal. 2. Once you start the live stream you can mute the audio on the livestream so it should not bother you. You can also close the browser. You will see in ZOOM on the top left a "live" icon, so you know when you are streaming live.
Now that we have our audio and video prepared, we need to combine the two in a way that will allow the final 360 VR video to be headtracked on our target platforms. To do this we must encode the audio to ambisonics.
OBS delay audio is one kind of common problem that occurs randomly. When using OBS to record or stream, the OBS audio may get out of sync with video due to malfunctioning of sound devices attached to the computer such as an external Mic. When the audio and video not syncing up correctly on OBS, you can try lowering the settings or updating OBS Studio. This article lists the best solutions that you can try to fix the OBS audio delay problem.
This article will show you how to fix OBS audio delay by adding Sync Offset or by adjusting some custom setting of the sound devices to 44.1kHZ or 48 kHz. A professional tool for recording and live streaming without audio or video out of sync issue is also recommeneded here.
This method is temporary solution to the audio delay OBS issue. Even though it is temporary, it has been useful for many users and can be used to prevent the OBS audio out of sync issue from occurring again in the future. Follow the below steps to know how to fix audio delay on Streamlabs OBS.
You can manually tweak the Sync Offset for the audio source impacted due to the audio delay. This may take multiple tests. Hence, be ready to have some patience. Once you have figured out the correct Audio Sync Offset, the audio must now be synced with your video and the OBS audio delay fix must happen.
Users can also know how to fix audio delay on OBS by adding custom sound settings. Even though there might be technicality involved behind the occurrence of this issue, it can be solved by adjusting some custom setting of the sound devices to 44.1kHZ or 48 kHz. Follow the below steps to know how to adjust the custom settings.
OBS audio and video still get out of sync during longer recording/streaming sessions? You can use HitPaw Screen Recorder, a professional tool for recording and live streaming without audio or video out of sync issue. The interface is user-friendly, enabling a user with little to no technical know-how to record or stream professionally. Below are features that you need to have a look at.
Having said that, we just had a look at different methods that can be used to know how to fix audio delay on Streamlabs OBS. The first method tell us to fix the issue by adding Sync Offset, which in return will sync the audio. The next method tells users to solve the audio syn issue by adjusting some custom setting of the sound devices to 44.1kHZ or 48 kHz. Last, but not the least, we also saw that HitPaw Screen Recorder can be used for recording or live streaming with best possible outcomes.
When I drive my kids they often watch cartoons on my android phone with the cartoon's audio coming out of the car speakers, connected to the car's audio system via bluetooth. Unfortunately, there is a very visible 1-2 seconds delay between the video (as observed on the phone's screen) and the audio. There is no such delay when listening to the audio directly from the phone's speaker. There is no noticeable delay when the phone is connected to the same car for the purpose of phone conversations. However, the combination youtube video on the phone's screen + audio from the car's speakers has this annoying 1-2 seconds delay.
This means then that the phone is encoding audio into data, and then the car is decoding that data back into audio. As a result, you get lag on the encode, and lag on the decode. Honda is aware of the issue, but as of 2018 has yet to release a firmware upgrade for cars with this issue. I do not know if 2018 Hondas still exhibit this bug.
and more likly to be on your phones end as you say it seems to be bad with you tube so it could be the processing of the video download and then decoding the video codec to display and the processing of the audio for Bluetooth could be that the phone CPU can't cope with that much simultaneously
University of Washington researchers have developed new algorithms that solve a thorny challenge in the field of computer vision: turning audio clips into a realistic, lip-synced video of the person speaking those words.
As detailed in a paper to be presented Aug. 2 at SIGGRAPH 2017, the team successfully generated highly-realistic video of former president Barack Obama talking about terrorism, fatherhood, job creation and other topics using audio clips of those speeches and existing weekly video addresses that were originally on a different topic.
Rather than synthesizing the final video directly from audio, the team tackled the problem in two steps. The first involved training a neural network to watch videos of an individual and translate different audio sounds into basic mouth shapes.
One way to improve the sound quality of your videos is to use an external audio recorder. But how do you synchronize the recorded audio track with the video from the camera when editing? In this video we demonstrate an easy method whose roots go back to the early days of talking pictures.
It probably looks a lot easier than it actually was. The hardest part about it? The timing! We had one take to make sure that we were completely in sync with each other. If a single beat, part or note was missed, that mistake would obviously loop for the whole video and it would have been a mess.
Get ready to explore how to fine-tune OBS for optimal performance, achieve the best video and audio quality, and troubleshoot common issues that might spring up during your live streaming adventures.
Imagine the possibilities: you can record and broadcast everything happening on your computer screen, switch between multiple camera angles, layer in external audio sources, integrate screen recordings, and even add custom overlays and transitions to make your stream uniquely yours!
Recording gives you the flexibility to record higher-quality audio compared to streaming. This not only results in better audio in the recordings but also offers more flexibility during post-production editing.
However, if you want more functions and possibility to save synchronization permanently in your subtitle file, then you would need to use tools such as Subtitle Workshop (Windows only) or Jubler (Java cross-platform).
Because it runs in the browser, SubSync has no installation hassles, and doesn't care what browser or OS you're using. It only takes a couple of minutes to synchronise before settling down for a couple of hours to watch the movie, so I find it's worth doing as a matter of course.
Every popular song typically has two different types of copyrights: one for the musical composition and the other for the sound recording. The musical composition includes the lyrics and the music, and this copyright is generally held by the publishers and songwriters. The license for this is a sync license.
To avoid legal issues and copyright violations when using copyrighted music, you will need to obtain permission to use the music directly from the holder of the copyright. Keep in mind that there is often more than one holder of a copyright for a song. You will need both a master-use license and a sync license for most popular music, for example.
Restarting your iPhone can be an effective way to address temporary glitches that may affect audio-video synchronization. By restarting, you give your device a fresh start, closing all running applications and clearing temporary memory. This action can help reset various software components, including those involved in audio playback, potentially resolving the video audio sync problem.
