What is the reason for the out of sync of the sound and picture? How to tune the sound and picture o

Then a new menu will pop up to the right of the sound options, select the audio sync option.

A new sound settings window will pop up, and you can see the audio sync options at the bottom of the sound options interface, with options for delay and advance, and the time to adjust in between.

The next thing is to adjust the settings, for example, the sound is faster than the picture subtitles, then select the corresponding time in the middle, and then click the delay option, and adjust the specific situation according to your own ** until it is synchronized.

If the adjustment is not suitable in the process of adjustment, you can also click the reset option at the back to restore it to the original state, and you can adjust it again.

Recorded live broadcast**or screen recording** often has a situation where the sound and picture are out of sync, which has bothered me for a long time, and I have tried many methods but it is not easy to get it, before I was trying to separate the audio track step by step, which was slow and tiring. Tonight, when I got 36 questions live broadcast**, I encountered the sound and picture out of sync, so I started to find a way again, and finally found a solution after doing it more than ten times**.

It's easy for me to forget what I know, so I'll write it down so I don't forget it, and I'll share it with everyone.

My steps are:

36 Questions: Fall in Love with You" live broadcast**I am direct**The live stream is not a screen recording, it is in TS format, I tried to use TS format in PR with this method or the same out of sync, so convert to MP4 format.

2. Convert the converted MP4 format to WMA audio format.

My computer configuration is OK, and it was converted in less than 1 minute.

5. Pull the WMA audio over to see if the sound and picture are synchronized?

Some**, especially those recorded by mobile phones or screen recording software**, are likely to be variable frame rate (VFR), the biggest problem with variable frame rate** is that the sound will be out of sync when editing in post, this tool is used to change the variable frame rate to a constant frame rate (CFR), and then there will be no sound out of sync.

What is out-of-sync? It's easy to tell that the picture and sound don't match. Although it is easy for the human eye to distinguish whether the sound and picture are synchronized, but the machine is not, for the ** device, it determines whether a frame ** and a frame of audio are to be rendered at the same time and**, relying entirely on the timestamp information carried by the data.

There are many factors that cause the sound and picture to be out of sync, and the following is a summary of the problems often encountered in live broadcasting. 1 If the audio source is too far away from the microphone, and the speed of sound propagation to the microphone is much less than the speed of light (the speed of light), then the timestamp given by the camera after collecting the picture must be much smaller than the timestamp given by the microphone to collect the audio at the same time, so the audio and picture will be out of sync. Solution:

The audio source is as close to the microphone device as possible. 2 Internal problems of the acquisition device, the camera and the microphone collect the sound**, the hardware will go through some signal processing modules, if the processing delay is unstable, it will lead to the time instability of the output data, which will lead to errors when the application layer obtains the timestamp, resulting in the problem of asynchronous sound and picture. Solution:

Very few hardware models will have it, and some jitter jitter correction needs to be done according to the acquisition parameters (such as sampling rate). 3. If the timestamp of the audio frame is not obtained at the time of collection, but is obtained at a subsequent link, there is a very high probability that the tone will be out of sync.

Questions. Okay, thank you! [Agree] [agree] [compare] [like] [like] you're welcome, oh, if it's helpful to you, give it a thumbs up.

Open the device, the sound and picture subtitles are out of sync, then right-click the mouse, and then a new menu will pop up on the right side of the sound options, select the audio synchronization option. The next thing is to adjust the settings, and adjust the specific situation according to your own ** until it is synchronized.

If the sound is slower than the subtitles, then select the corresponding time in the middle, and then click the advance option to adjust it multiple times until it is synchronized. Of course, if the adjustment is not suitable in the process of adjustment, you can also click the reset option at the back to restore it to the original state, and you can readjust it.

Introduction: **Refers to various technologies that capture, record, process, store, transmit and reproduce a series of still images in the form of electrical signals. When the continuous image changes more than 24 frames per second, the human eye cannot distinguish a single static image according to the principle of visual persistence. It looks like a smooth and continuous visual effect, and such a continuous picture is called **.

Technology was first developed for television systems, but has now evolved into a variety of different formats to allow consumers to record them. The development of network technology has also prompted the documentary segments to exist on the Internet in the form of streaming** and can be received by computers. **It is a different technology from film, which uses photography to capture moving images as a series of static images**.

If the computer screen and sound are out of sync, you can try the following methods to solve this situation: 1. It is related to the operating system. If the current operation of the Cong Collapse system has not been reinstalled for too long, or has not been carried out, cleaning garbage, registry and other related optimization operations will cause the picture to be out of sync with the seepage sound when watching.

It is recommended to use 360 Security Guard or other similar software to clean up. 2. It is related to ** software. I've used gomplayer, kmplayer, if you're **rmvb, flv, mkv file, you may have a "stuck" phenomenon with grom, kmp won't.

It is advisable to find a suitable ** software. 3. The grade of the CPU is affected. If the CPU processing power is not strong, when encountering a large file of **MKV, it is obvious that the sound and picture will be out of sync.

Summary. The computer **** file is, the reason why the picture and the sound are not synchronized is caused by a system error, and the specific solution steps are as follows: 1. First open the computer, find the **file** in the computer, that is, the **file that the picture and sound are not synchronized, and put it in an easy-to-find folder for backup.

2. Then open the iQIYI universal device on the computer, and select the open option on the software interface. 3. Then the window to find the file will pop up, here select the file you just saved, and then select the open option. 4. Then enter the **screen**, right-click the mouse on the interface, select the sound option in the pop-up right-click menu, and then select the audio synchronization option.

5. Then a new window will pop up, which is the interface for setting audio synchronization, that is, the operation interface for adjusting the audio delay or delay. 6. Next, let's talk about the method of adjustment, if the sound is in front, the picture is delayed, click the delay option, the middle is the delayed time, select the corresponding time and then click on the delay, the selected time will be accumulated until synchronization. 7. If the sound is behind and the picture is in front, then click the advance option.

It is also to choose a good time, and then click the advance option, and the time will also accumulate until the picture and sound are synchronized. 8. If the adjustment is wrong, it doesn't matter, you can click the reset option at the back and then re-adjust.

Excuse me, but please go into more detail?

6. Next, let's talk about the method of adjustment, if the sound is in front, the picture is delayed, click on the delay option, the middle is the delayed time, select the corresponding socks base time and then click on the delay, the selected time will accumulate until synchronization. 7. If the sound is behind and the picture is in front, then click the advance option. It is also to choose a good time, and then click the advance option, and the time will also accumulate until the picture and sound are synchronized.
