how to fix audio out of sync

[lacus889]

i was watching NSFS-476 and after the first minute the audio is out of sync for maybe around 2-3 second delay, how to fix it permanently?

Where did you get it? It's likely (hopefully!) just a difference in the framerate.

You are not describing exactly - were you watching STREAMING video on web page - or a saved video inside your PC.

If the video is streaming with audio out of sync, there is nothing you can do.
It is the problem of streaming page.
If the video is downloaded, in your PC and the audio is out of sync, you could fix it with the video editing tool avidemux.

In avidemux there is under the Audio Output available the option > Shift > mark this in small window on the left
and in the bigger window, you just try to enter the right number of milliseconds, (3 seconds is 3000 ms).

Very true, @aronora !! I just watched it on supjav.com, the Streamtape version, and it had perfect audio throughout!

A ripped title from a streaming site can be fixed as well, the easiest way I've found is using mkvmerge.

Steps to Sync Audio with Avidemux

Initial Setup

Open Avidemux: Launch the Avidemux application on your computer.
Load Your Video File: Go to File > Open and select the video file you want to edit.

Adjust Audio Settings

Enable Shift Option: In the Audio output settings, check the box for the "Shift" option. This allows you to adjust the audio timing.
Set Video and Audio Output: Ensure that both Video output and Audio output are set to "Copy". This prevents re-encoding and maintains the original quality.

Determine Sync Adjustment

Test Playback: Play the video and observe the sync between audio and video.

Adjust Timing:

If the audio is ahead of the video, enter a positive value (e.g., 200 ms) in the Shift box to delay the audio.

If the audio is behind the video, enter a negative value (e.g., -200 ms) to advance the audio.

Save Your Changes

Save the Edited Video: Once you are satisfied with the sync, go to File > Save > Save Video... or press Ctrl+S. Choose a name and location for your file.

Tips for Accurate Sync

Start with small adjustments (around 200 ms) and test playback after each change.
Use visual cues in the video, like claps or other sounds, to help determine the correct sync value.
By following these steps, you can effectively sync audio with your video using Avidemux.

You better try more solid sources for download.
I usually check my approved sources - like 7mmtv.sx.
here you have 5-6 different sources (in buttons down the video window)
Some of them are 720p.

Here, on page javsiri.cc is the same movie available with reduced mosaic, up to video quality 1080p.
(options - 480p, 720p, 1080p) and - audio is in sync!
Here the video is streaming in .MP4 format and for download from this site could be used
Chrome extension Douga Getter >

apparently all the downloadable source have the same issue, so i just fix it with Avidemux and now everything is good.
but i dont understand why it can happen, the video come from the same source, but one is glitched and the other is not. anyway thanks for the help

Downloading it from a streaming site redoes the container, which is what holds the sync data, so that gets lost.
It's not an issue when the audio is perfectly synced in the first place, but that's not always the case.
