Question Trouble synchronizing sound effect with video track

Hi,

I'm trying to synch a clip on a timeline and an effect oh the other just underneath so that they will synch when rendered?

I have a very short clip of two glasses of wine clinking silently because there is no sound effect. Found one and placed it on a separate timeline just underneath the clip so both of them would be in synch so I could here the clinking when the glasses touch. At this point no problem.

When I render the whole project where that part is included I have more than an hour to wait before I can see the result. After more than five tries, the sound is out of synch by a fraction of a second.I did displace the sounf effect by a fraction of second and rendered to no avail...does anyone please have a fix? Thanks.

Hi Michel

The first thing I recommend you do, is to create a new test project.
Import only the short glass clink video and sound effect audio track
To get the best sync, make sure to "Zoom In" on the timeline (using wheel of mouse), so that you are down to the Frame by Frame level. Each frame mark on the Timeline Ruler, should be about 1 cm apart.
Glasses connecting should be in the centre. Grab hole of Timeline Cursor with Mouse pointer and drag left/right to find connection point.

I found a random video on YouTube of what you want to achieve.
It looks like the sound actually starts a short time after you see the glasses connect.
On a 2nd Audio Track below, I imported a sound effect from my own library of sound effects, and placed it about one frame after glasses connect.
Doing this created a perfect sync.

If you get it to work in the test project, select both video and audio parts and press G for Group, so that they are now locked together.
You can them copy and paste synced items back into your main project.

If you still can't work it out, upload your .veg file of test project, short video and sound effect to Google Drive, and share the link on the forum here. I can then download your test project and check it out.

Hi Derek,

My glass of wine klinking doesn't work. I'm attaching a veg file made with VP20. Both files were Grouped and not only that I rendered it as a mp4 file and it is still out of sinc when rendering within the project where that file is included. Out of means...thanks for the help.

I will need a copy of your video and audio file as well !!!
The .veg file does not contain source media.

Upload to Google Drive, if you have a Google account.
drive.google.com/drive/my-drive
Once uploaded, you can create a download link to share.

Hi Derek,

Before I leave you the media files, I'm trying something that might work. I rendered the last 25 seconds of my project that lasts 53 minutes. That render is called Project 2. My synch problem is situated 6 seconds before the end of my project. By trial and error, (6 renders) I finished by synching the klinking of my glasses of wine with the ding sound. Short time of 10 seconds of rendering every time.

Now I'm rendering the first part of my project 53 minutes minutes 25 seconds, Project 1.

When that is finished I will join both Projects hoping that the klinking will not be disturb and will ding at the right moment...I'll let you know in a few minutes.

Hi Derek,

I'm still stuck with my sync. issue. I don't understand why the voice and movement of mouth are easily in sync and the ding of two glasses touching is out of sync, and I just can't seem to fix it. I DL an hour ago a mp4 file of glasses of wine klinking (jut notice that I cannot attach it to my message). I inserted that file in my project, rendered it and again still out of sync. I did (G)roupe, my two Vid. & Aud. files from my original files but as soon as they get rendered within my project, out of sync? So my last test (see previous message) did not work

You suggest that I DL on the Google drive, I don't have access to that, I don't understand why you want me to do that? I'm really out of ideas??

In a few words Derek, I just don't understand why the render process cannot maintain to perfectly synched files intact after rendering??

Michel, what format is your "clink" audio?  Whatever it is try converting to "wav" and use that.

I'm asking from access to your small video file and small audio file, so that I can TEST them both on my computer and work out what is going wrong.
I can't help you, if I don't know what you are working with.

Do you have at least one Google account?
If you have a Google account, you automatically have access to Google Drive, which is a FREE file sharing service.
You can use any file sharing service you like - there are many to choose from.
Most people online have at least one Google account, because they have Gmail and/or a YouTube account.\

I've never heard of anyone ever experiencing your problem.
It makes me think that one of the files is using a weird format, frame rate or audio rate, that is causing some very rare problem.

Eric's idea is a very good idea.
If the original Audio file is using some weird format or setting, it could be the cause of problem.
Converting the audio file to .WAV format is a great idea.

If the Video track is using a weird Frame Rate that is completely different to your Project Properties Frame Rate setting, that could also be the cause of the problem.
 

Hi Derek and Eric,

To Eric thanks for the suggestion, but it did not work there is a delay between the glasses touching and the ding sound of about half a second.

Derek I'm attaching as you asked the video mp4 file without watermark, there was one on the DL version and I had to remove it and also two audio files of the same sound (mp3 & wav). The last render was made a few minutes ago with the wav file to no avail.

Thanks fir the help, really appreciate it.

I just noticed that your site does not accept .wav files.

Thanks fir the help, really appreciate it.
