Audio/video are out of sync

borate

If you don't have the energy or time to follow the easy steps Nat has outlined, then you indeed may have wasted your money...but Videopad is not the cause of the sync problem.

Hello, I just upgraded from free and this is my first paid version video and my audio is out of sync. Mine is in mp4 and audio is synced perfectly with video when each video clip plays outside of being loaded into videopad.

When I load it into the editor, both video/audio clips go out of sequence. I can't see anyway to sync it up. I even tried snapping it forward a little but that didn't help as over the run, it would be out of sync again. This has never happened. I uploaded to onedrive, here's the link. https://1drv.ms/f/s!Anz\_KbP9-HIijj0OlCY6yg7eR1pH

Thank you for any help..

The sync problem is obvious in the exported file, but what's needed to pin this down is the project itself.

Load it to the timeline, then follow these steps ... and someone will check it out.

1. In Videopad click the FILE menu, then SAVE PORTABLE PROJECT AS. Save to any convenient folder.

2. Open the folder that contains the saved files and ZIP them all.

3. Upload the zip file to MS OneDrive.

4. Make the uploaded file public (share it) and copy the shared link.

5. Paste the link into this forum.

Is there a video that shows how to to do the unlink?

I'm not all that smart when it comes to written instructions, sorry.

At the left bottom of a linked audio clip one of the icons looks like a sideways figure 8 (a link). Click it, to UNlink.

A right-click on either the video or the audio of a clip on the timeline will list a RESTORE link choice as well.

If you have a clip on the timeline with its associated soundtrack (the usual situation) then to unlink the soundtrack...

Right click the video track.
Select the top option from the menu that comes up which is Unlink from Audio.
Job done.

Right click on the soundtrack
Select the second iten down the menu that comes up which is Unlink from Video
Job done.

So there you have two ways of doing the same thing.? Once you have the tracks unlinked they can be moved independently.

You can restore them to their original state using the same menus which will have the options to Link this time.

Note: If you wish to keep (fix) the adjustments you make to the relative position of the tracks, you need to Group the tracks.
Press the SHIFT key down and keep it down
Left click the Audio track and the Video track.(both will highlight)
Right click either track
Choose the option Group selected clips.
Job done.

The grouped clips will now retain their relative positions to each other.

Hopefully this is the link for the file you need, it's zipped: https://1drv.ms/u/s!Anz_KbP9-HIijj9U3eluBy1d37US

Nationalsolo I saw that in the other post, it didn't work. If I move the tracks, then it still gets out of sync anyways as it plays. The video and audio were recorded at the same time. Normal mp4, no out of sync problem. Upload to videopad, it's out of sync. Snap forward, move back, it will get out of sync sooner or later, seemingly no way to sync using either method.

Is there a short instruction video on this?

It does not make any sense that if the original were recorded fine then why would you have to adjust anything.

Yes, that is what I'm trying to figure out. If recorded in mp4, why is it out of sync when loaded into videopad? Hopefully the guys who have been helping have some answers as I'm sure this could be a future problem.

Perhaps the devs will look into this seldom reported oddity. The audio is approximately .500 faster than the video, but appears to vary by clip, which throws off the sync progressively. My take is that the fault is with the source, either the Livestream recording or the Freemake conversion.. Try it with a direct mp4 recording without Freemake.

It was corrected.

When specifying a new speed, enabling the "insert transition frames when speed is reduced" box seemed to help. Prior to checking that box, even after the offset was eliminated at the head of the longer clip ... and VP played it IN sync on the timeline - it still ran amok when exported.

Where is insert transition frames when speed is reduced" box?

Right-click the audio clip. CHANGE CLIP SPEED. Lower the speed. Note that the "insert transition frames" box becomes active, and can be checked.

Hi team2win

Please don't shout....(Use capitals!) I was answering a query........

"Is there a video that shows how to to do the unlink? 

I'm not all that smart when it comes to written instructions, sorry." 

However your comment does explain what you are experiencing. I agree that if the original MPEG4 recorded fine and played OK it's odd it becomes gradually out of synch when dropped into VP. What player did you use that showed it in synchronization before you loaded it to VP?

From the point of view of VP a possible correction might be obtained by....Unlinking the audio and video as I described above and then right clicking the Audio track and then selecting Change clip speed. Changing the speed of the sound track slightly (keeping the audio pitch unchanged) will stretch or squash the track whilst keeping the start point the same. This can help where there is progressive de-synchronization of the track not simply a displacement. (A reciprocal correction can be made by treating the video track in a similar way as Borate has suggested.)

Ok, what you are describing is quite a bit, especially since I'm not really a video/audio techie, lol. Obviously the videopad software is well more than my capabilities or knownledge at the moment. I don't know where a person is suppose to learn all of these options. It's almost easier to make a new video and see what happens on another upload. Thank you everyone for your input.

Well, I did my 2nd webcam video from computer and once again, audio sync delay. mp4 no delay, put into videopad, a delay. I am on computer and it seemingly opens it up in whatever software they use, might be whatever windows 10 uses as it says 'movies & tv' in upper left corner. Sad

borate

'Movies and TV' is a Windows-app media player.

Transfer your webcam this way - eliminating any intermediate steps, and report results.
