X9 Pro audio fade out causes scratchy blip

[lata]

Hi Ilene

I have not heard anything, I would have thought Auz would have been in touch with you???

As for correcting the blips,
After rendering the blips show usually during a fade, if you use the scissors to cut the blip, then mute that section.
Would of course require a final render, but using Same as first Clip should be fast.

But yes I agree there is a problem using X8, X9 and 10. CVSX7 seems ok
Whether that is associated with the intro of Audio Ducking in X8 is debatable, but could be possible.
Certainly something has changed.

Hi
I haven't heard back from Auz. I think he was on vacation, and I was away a few days too, so I thought I would reach out to him tomorrow. I will keep you posted

I have used the scissors to help correct the blip... it's not quite the same... you lose the fade you want from one clip to the next, but it's better than a scratchy blip!

Hopefully, they can figure out what this is as it is painfully problematic! Whether it's audio ducking or something else, the fact that it is so random and doesn't occur on every fade out makes it very hard to identify. I'm not an audio guru, but is there a reason that audio cannot fade out to absolute zero? And why is the blip undetectable on playback while editing and only audible on render. If you scrub the time line while in Edit mode you can hear the blip, but on regular playback you don't. Only when the project is rendered.

thanks for staying on top of this with me!

best
Ilene

Hi Ilene & Trevor: I'm still interested in this too, just haven't been able to repeat the fade audio glitch to share with you. It was quite a problem on some concert projects I did about a year ago but was random like Ilene said and I somehow fixed the problem by changing the location of the fade or lengthening it or silencing the end of the fade with the rubber band although it never quite goes to complete silence. It seemed to happen when the audio fade was from quite loud to attempting silence. Another fix I remember doing at the end of a concert video with loud clapping, I went to the end of the audio when the clapping naturally fades and cut out that section and tacking that onto the place where I wanted the video to end, but that required dinking around with the audio difference in the two audio clips I combined to make it not noticeable, had to spend time playing with the rubber bands to get audio sound not to "give away" the connection point.

Bottom line.... shouldn't have to go to great lengths and spend enormous time on smething that shouldnt be happening. This was NEVER an issue in X7 and lower. Fading oit audio is a basic function of editing software. It's frankly ludicrous that we are even discussing this.

Yes it shouldn't be happening and it'll remain a problem until Corel fixes it. The solutions proposed in this thread are ineffective because the location of the glitches can change if the VSP is modified.

Downreving an X10 VSP to a X7 or lower VSP is not practical as it takes too many steps and many of the filters cannot be downreved in any event.

[Ilene]

Exactly....!! Bravo!!
I have thought about opening x10 project in x7 and just rendering the audio file. Then bring the audio file into x10 and render out project.

Thr problem is Ive seen the length vary by a few frames and throw things off and, you have limited flexibility if you decide to make any changes. You would have to go back and do the process again it's painstaking!!!

I didn't read the full thread, but I do remember problems in audio cross fades in X4.
My workaround is to use the gain in attributes during the first run of the edit
and only at end tweak a bit with the rubber or via audacity.

[Ilene]

I never had these problems in any from x7 down to orig ulead... ive used them all -- I havent changed my methodology... so shouldnt be happening.

Again... shouldn't be a need for any workaround. This is basic functionality!!

PLEASE report issues to Corel so they can fix -- the more people they hear fr the greater the chance they respond w a fix

Glitch on render only--- has to be a problem w render engine.

Hi Asik

Attached is a VSP that will open using CVSX7, rendering using X7 does not cause any problems.
I do not know if you have X7, but trust us its ok.
Open in X8, X9 or 10 and a blip occurs towards the end of the project 00:02:04:28
You have to render via share.
You can hear the blip when playing the new file, or add to timelines to view wave form via Sound Mixer

unfortunately the problem is rather random I have problems replicating except for tweaking Ilene’s files.
But Ilene also used Instant Projects, made a few edits then caused the problem, clearly using files provided by the program.

[asik1]

No, I haven't install X7 yet,
But take a look at that, as I just open it in X9.2 ,

open the mixer and I don't see
the fade-in of the second clip

So I ticked the fade-in , and now no blip
but .... wait there is more....
I reloaded the vsp , same as above shown.
So I dragged the second clip to the right, off the mix point.
and redraged it to overlap the first and still , no fade-in applied to it
even as the croossfade is set in my preferences

** I just made a test,
New project,
took that mp3 file to a track
cut it and overlapped, the fades applied correctly.

[Ilene]

Unfortunately this isnt a valid test... as the problem rately occurs with just 1-2 tracks... it starts to happen when there are more audio files.
Also it happens when there isnt a cross fade on same track but when they ovelap on audio track 1 and audio track 2 as often as if there is just a cross fade on a single track.

So while this may seem clear now, it may not stay clear as you advamce in the project and add more audio tracks.

It is just SO RANDOM!!

But bottom line is... NEVER happened in X7 and below

you are viewing the project, it does not show until we render the project to our output file, share - same as Project Settings
The resultant file can be added to the overlay track 2, view in sound mixer will show the blip towards the end.
The only reason for the image is to extend the project a little, as the blip will show on the last frames.
Interesting that the blip is a little beyond the audio file.

Sound mixer and expand the timeline to view wave form

This is one I rendered earlier, one to Mp4 ( top track) and one to AVCHD (overlay track) , both show the blip

OH........ Got you,
Yes I can replicate the problem , there is no blip if it's just fade at the end of a clip,
but once there is a crossfade somewhere before, the blip comes to life at the end.

well , we do have FF template maker so why bother with blips....

So are you saying that we should render a project and then edit the audio in FF and finally re-render the project in VS? If that is the suggested approach then it'll not help VideoStudio sales as many of us want a product that works without having to conduct more work to address an obvious bug.
