That's awesome - I did not know that. Do you think that will fix the issues that people had going from 12.6 to 14 or is that "flexible layout" merely a UI choice?

Hugly said: "Good day,

Which issue persists?"

The issue reported by the OP (where 12.6 works with certain non-standard FPS w/o desynch but desynch occurred after 14.0).

So you are referring to V14.0 when saying the issue still persists?

Or whatever version is currently being used. What I DO know is that I was also having the same problems as the OP at the same time the OP reported it here but did not have those issues prior to the update which changed the UI, the containers, etc.

I just never came to the forum about it then as I was able to fix it.

So, whatever version is running now still has this same problem, if that makes sense.

Referring to sync issues caused by variable frame rate that's simply untrue. Furthermore, V12.6 had a list of bugs, I never wish to see again, although I have I license to run it.

If you run V14.0, whatever the reason is, I strongly recommend upgrading to the most recent release, which is 2020.1.1.

Hi,

I make a family video each year for christmas. In the last years I did it with Lightworks.
But I always had problems with audios out of sync. I had read the forums, but did not find good solution. The best way was to restart the app frequently.
Now I try to make a new video with the Lightworks 2020.1.1.
Before I start I converted all of my audios to a constant rate audios.
After I start a project I upload only one audio file and start to play it the red moving point is async with the audio and if I copy it to a sequence it is obvious that it is out of sync.

Format : MPEG Audio
File size : 324 KiB
Duration : 20 s 715 ms
Overall bit rate mode : Constant
Overall bit rate : 128 kb/s
Writing library : LAME3.100
major_brand : isom
minor_version : 512
compatible_brands : isomiso2avc1mp41

What can be the problem?
Thanks.

I use Win10.
I3-7020U 2,3Ghz
16 GB RAM

I see, that usually hugly answered for the questions. Is this information enough? Or do you need something else?
Or do anybody read this post?

Idk if it's much help but I just use the auto button under frame rate selection when I'm making the project and it works most of the time

The full Mediainfo text report for the source video and the audio is usually required for solving out of sync issues.

That is a little under powered.

Hi,
Thanks for the answers.
I did not write the media info of video files as I had problems with a single audio file and I added info about it in my previous comment.
But I tried to start with "auto" framerate and now it works if I restart the app. Yesterday it did not work after several restarts.

Now I have the out of sync problem again but I was not able to simply reproduce:
If I start a new project, and import the problematic file there, then the app play it correctly. Thats why I think it is not a resource issue.

I have two types of videos. I put one from each type to my sample project and it worked properly. So it seems that some other edit command or more files in the project can cause this out of sync issue.
