Audio leaking behind in export

Hello,

I'm experiencing file issues and it gives me YouTube blue balls.
When I export a video and open it on vlc the audio is leaking behind. When I open it on movies and tv it skips frames and makes it look weird.
It seems to leak behind even on YouTube: https://youtu.be/jDr4yQGdUyQ

Greetings,


Rick

I don't have any idea of what your original clip looks or sounds like so it's very hard to understand what you're seeing.

Can you take a screenshot of your project timeline and attach it here? Even better would be to make a screen recording showing what the preview looks and sounds like in PD, and then put it on YouTube.

Here, I screen-recorded the whole process. Down the line I have been experiencing some more issues, which are also featured on the video.

Thanks for making the screen recording. You're clearly using the trial version of PD17, and it has a significant number of limitations. See the Download Information tab on this page.

You also have lots of things going on in the video, and it's still difficult to tell what is intentional and what is a problem. I believe you're pointing out that the audio is wrong when you do the brief blurry cut @ 4 seconds on your timeline, but your timeline is so small that I can't see what's going on.

I also saw that the first time you produced the video, it was terribly distorted, but other profiles worked better.

If you use File > Pack Project Materials... and save everything to a cloud folder, pasting the link to it here will let me (and any other forum members who want to help) download it and test it on our systems. You have to be comfortable sharing your project and the source clips, but that's the best way for us to really understand what's happening.

Thank you for responding again.

I have compiled up a video comparing the output video from PD with the input clip and the preview on PD. In the output video the sound is weirdly out of sync. This video is here.

I have also included the project files in the attachment.


I use the trail version to explore problems before I consider buying, so that's why I'm using the trail version ""wink"" .


EDIT: Forgot to include this too.
I also made a comparison with a video on my SL2: https://youtu.be/slvVp9u6OTs

I'm afraid the videos still don't give me enough information to help. As I said earlier, using Pack Project Files is the best way to let us see the exact clips and edits that you've made and compare them with what your videos show.

Also, you cannot use the Attachments button on the forum, because your clips will be much larger than the 5MB size limit. If you have a DropBox, Google Drive or OneDrive account, please upload the project files there and pots the link here. If you don't have an account, please let me know and I can give you an upload link to one of my accounts.

Thanks very much for sharing the project! I can now see all of the edits you've made, and there are two sections where you've made changes that affect the audio.

The first is in the 3rd clip, which has been sped up ~16x. There is a box that allows you to keep the audio or mute it, and it's set to keep the audio, but you have muted the clip separately so there is no sound in the produced video. See the attached pic showing the settings.

If the clip volume is set to normal, you will hear a "fast forward" sound. I restored the audio in my test production.

On your 5th clip, you've used Audio Editor to add an echo and reverb effect. I've heard that clearly in the produced video, but I wasn't sure if that was intentional or if that was the problem you were posting about.



I left that audio unchanged and produced the project. Can you watch it and tell me if you think the problem is still there?



I also watched the comparison clip from your SL2, but I can barely hear any differences between the two clips even with headphones on. In the produced version, I hear your voice as slightly more distinct from the background music. Can you describe the problem in more detail?

Hello again.

I want to correct a mistake at the beginning of the thread and I did another test myself.

First of all, I did not mean leaking behind. It is instead the opposite, it looks like the audio is playing earlier than the actual video. Don't know how that slipped through.
Strangely, when that video is on YouTube, it does not seem to leak forward. You can see it here.

For some reason, your linked video is not available.

I hadn't noticed any delay between the audio and video, but one thing you can try is to change the Timeline frame rate: to match your source clip, which is 25fps.



Your project is currently set to 30 FPS (NTSC), and that can sometimes cause sync and frame skip issues with 25p clips. You should also be able to use 50 FPS (PAL).

I will try to use that.
Also, I updated the link.

UPDATE:

Syncing timeline frame rate with output and video file frame rate works.

However, I'm worried that different video files with different frame rates would cause problems, wouldn't they?

Ideally, all clips in a single project should have the same frame rate (like 30p), or be an exact multiple (like 25p and 50p).

If you mix 25p clips with 30p or 60p clips, PD will have to pad or remove frames from any clips that don't match the timeline frame rate. However, there isn't an easy way (that I know of) to tell in advance whether that will cause problems or not, since it greatly depends on the visual content and the specific frame rate combinations.

I always set my project's frame rate to match the highest FR clip, which for me is 60p. Any 30p clips get their frames doubled and they don't cause any issues. If I had a 50p clip in the mix, PD would double every 5th frame, which might be noticeable in certain situations and be completely undetectable in others.

For your future projects, see if you can get all your equipment to record at the same rate. If that isn't possible, start with the project set to match the highest frame rate of your clips. In some cases, changing the timeline to match the lowest clip frame rate may give you better results, so keep that in mind if you ever have a difficult project.
