Quote Hi Everyone
I have an issue with sound hiccups, what I mean is, when in my project I join 2 files, even though I use a transition for the video and overlap the audio of both files and even fade out 1 audio as the other audio fades in I get a little sound break in the audio. Anyone with a suggestion to fix this?
Thanks

Sometime you get a noise in preview, usually that noise is not in the produced video. You would have to do a produce of just the transition area, then play the produced video to see if there is any noise.

Thanks for the reply,
yes I have done that and every at join in my project where 2 sound files meet, the sound files have the glitch/hiccup/break, (very tiny), but there shouldn't be any!
I tested a different editing program, (on the same level as PD and there is no issue when it comes to this situation we are discussing, but the program has many other issues that i don't like.

You mention that you used a transition, but your screenshot doesn't show any. Instead it shows that you've split the audio and video of both clips, and then simply abutted the 2 video clips while overlapping and manually fading the audio clips.

PD sometimes does weird things with situations like that, so the first thing I would try is to undo those edits (or at least restore clip00113's video length to match the audio; select both sections, then use Link/Unlink Video and Audio to have PD treat them as a normal AV clip again. You'll also have to link clip 00114's audio and video together).

When you have the two intact clips, place them up against each other and apply an actual transition across them. You can use No Effect if you want a visual hard cut there, but PD will automatically (and hopefully seamlessly) blend the audio. You'd want to set that transition's duration to 2 sec to match your screenshot, and you can experiment with having it be a cross or overlap. One style may be a better fit than the other each time you join clips.

Hi Optodata,
I added both 113 and 114 video files into a new project timeline, (as a test) but I had to split file 114 (audio and video) because I wanted the video from the very start but I needed to pull the audio forward. (Its music playing on top of a video)
The best results after many attempts are when I use the fade transition and used the overlap style. I get a very small glitch still, even after I make a rendered clip of the project I will add a sample of the sound file so you can hear it. It's only a small break but there should not be any! The hiccup is around the 10-second mark. Like I say it's not big but when you get 10 15 in a complete project it is annoying.
When I use "cross" in my transition, there is no hiccup or break in the sound, but it's not what I want, the cross feature fades the sound completely out at the end of file 113 and fades in the sound of file 114. I want the 2 sounds to overlap, with no loss of sound other than the change of sounds.

I actually hear 2 breaks, one at 8 sec and the other at 10.

I thought about mentioning this in my last post, but it seemed like your edits might have been causing the issue. Now that you're saying it's still there, I'm wondering if running PD on an un-activated Windows machine is causing some of these headaches. Stranger things have been known to cause PD to stumble.

With that said, it might help to share both of those clips by uploading them to a cloud folder so other people can test them out. Sometimes it's the particular audio codec that's used in the clips that causes the issue, and sometimes it's the profile used when producing the final video. Either way, having another system to test the clips on can be useful.

If you're concerned about privacy, which you might be as you've blocked out the video image in your screenshot, you can either share a couple different clips taken with the same equipment, or send me a private message with a link so they won't be publicly shared. Whichever you're most comfortable with.

Did you get this figured out by chance? I am getting the same sound hiccup if I add a video over the top of my existing clip. For example, I add a small video window such as a gaming clip while I am talking, it hiccups right after the new PIP opens and then right after the PIP closes.

Optodata thanks for your help.
I don't understand how you feel my edits may be the cause of this issue, I have edited 100's of hours of video, but of course, there is always something to learn and you seem like you want to help beat this issue as bad as I do, lol so I have attached the 2 clips as you suggested, and here is what I need. (I will try my best to explain)
Add clip 1 as the first clip on your timeline and leave as is, then at the 2:11 mark of clip 2, that is where I want the video to start on the second clip but I want the audio on the second clip to start at the 2-minute mark of clip 2 so of course, you will need to split the video and audio of clip 2 to make this work.
I want a fade transition added between the 2 videos with no break in the audio. Normally I would just split both clips (audio from video) add each audio clip to 2 different tracks and have them overlapped a little, then fade the first one out and fade the second in.
Looking forward to your results, ( if you can follow my instructions)haha

It would probably be best to upload you pds file exactly as you have it for the issue. You reference "2-minute" mark, both your clips combined don't add up to 2 minutes, I assume maybe 2sec 11 frames. Which then brings up a second issue too, clips are NTSC 60 fps, so 2:11 is different if you really have the timeline set to 60fps or by chance you have it at 30fps.

Your earlier posted "Desktop sound test.m4a" audio file clearly has a totally dead spot which creates the so called hiccup.

Hi Jeff yes you are correct! Sorry about that! My timeline frame rate is 60 fps.

Clip 1 is ok, and as you will see in the video in the second clip, a guy is escorting a lady in through the open door, and also in the second clip you hear the music start, but it starts before the guy is escorting the lady in, but I want the music to start as they enter the room.

I have attached the pds file.

As a short term work around, try using the "Profile Analyzer" on the produce page and then use that custom profile created and make sure the "Fast video rendering technology:" lower on the produce page has SVRT checked. See if that still has the hiccup.

FYI, not related to the audio hiccup, editing in the fashion of your pds file will have serious issues with audio synch. What you have done is created a shift between the audio and the video of the second clip, a shift of 9 frames or .15 seconds.

Hi Jeff, I don't understand what you mean by "I have created a shift between the audio and the video. There should not be any reason why I can't blend these 2 clips together seamlessly even though I have separated audio of the second clip and dragged it forward or backward, it should not matter. I can do the very same thing with a different program and its perfect!
I will attach a copy so you can hear it.

Since you unlinked the audio from the video, you simply need to be very careful that when you trim one you trim the other or that you simply don't change the relative positioning of them. If you slide one relative to the other on the timeline, you obviously change the sync from that action. You can see the effect of your editing by looking at the end of the timeline for clip 2, audio and video do not end at the same time, should they? One can't simply trim to match because it's relative to the editing that caused the shift.

You basically have a clip 2 video that is 25:36 long and a audio that is 25:45 long so one needs to always maintain the original alignment so you don't change the audio to video sync.

Did the SVRT suggestion correct your audio hiccup or not?

Hi Jeff, yes I know the ends of the audio and video in the second clip are not the same length, this is just a test because I am having this hiccup when the 2 files meet. this as nothing to do with the end of the file. In my original project, I have the sound and video the same length. AGAIN I can do this with a different program without any problems. I provided you a sample.
And no the SVRT suggestion did not correct the hiccup.

I've had lots of issues with PD18, to the extent that I stopped using it until CL can provided some very needed patches. I've got the perpetual license so no patch since 12/19 from an extremely buggy release, subscription has had some intermediate patches but still lacking from forum reports.

Attached pic PD18_Origpds_encode.PNG shows what your original pds file does on my platform. With basic CPU encoding for produce, you see it creates a audio flat spot, with SVRT that spot is gone. Too bad it didn't help you at all.

Attached pic PD17_18_Modpds_encode.PNG shows how I typically edit these overlap scenes. I only do it this way as it gives me lots more control of both video blending and audio blending with key frames. However, you can see again that this works totally fine in PD17 produce with no audio flats, the same pds file in PD18 when produced produces two flat spots in my release.

Looks like your mileage will very. Another issue for CL to resolve more permanently vs simply trying to suggest a work around.

Hi Jeff -

Since you posted that PDR17/18 comparison I've been trying to replicate the audio glitch in production, but I've faile dismally. I've used various clips from different cameras, all overlapped & keyframed in a similar way. See attached screenshot.

I haven't been able to generate that flat spot you showed. Admittedly, I wasn't using the sample clips newfielander provided.

Not doubting your observation at all - just can't replicate it here.

Hi ynotfish, whats your guess to why i'm getting these hiccups?
Thanks

Sorry, I don't have a guess to offer you. Jeff is far more knowledgable & experienced in these things.

I do know that, over many years, PDR has thrown up these sorts of audio issues from time to time. In many cases they can be replicated but in some cases not. Sometimes, the particular clips or the PC setup might be factors.

I'd have preferred to do the tests using your clips, but you must have removed them from OneDrive.
