X9 Pro audio fade out causes scratchy blip

[Ilene]

hi Trevor..
I added files to the one drive... please confirm that you received. I SP'd the project with stock images... hopefully you can replicate the glitch. thanks so much!!!

Hi Ilene

thanks for those files, yes I am having some issues with the audio and have managed to create those glitches.
I am also having some strange issues with Audio Fades, Crossfades, sometimes does not X-fade but sets a fade to one clip.
Don't understand that.

I will do more tests so far both X9 and x10 are suffering

I am looking at a workround F6 Preferences deselecting Apply audio Cross-Fade Automatically
Then applying the fades via the timeline – attributes fade ramps.

First test using X9 looked good?

Hi Trevor,
In response to your work around -- perhaps this works in 9 and 10... it never worked in 8. This is actually my first project in 10, so I will try it.
I don't have my project settings set to put in automatic fade in/out on audio -- and if I do, I often manually adjust. I have tried many times and unfortunately it's not consistent with the results, of putting cuts and then fades at the end of a track to get rid of the glitch, or to extend the fade out... beyond the 1 second default -- I have not found it to be a consistent solution.

keep in mind that the most challenging part of this glitch is I never know which track it's gonna rear it's ugly head on... in the project I sent you it was the 3rd track. It's almost never on the first track, and perhaps never... mostly it's starts by the second, and may skip the 3 or 4th and appear again... it's completely random! all song files are always the same format -- and out put is best for me as mp4 or mov -- I can use either. I just don't know what the variable is that causes it.



thanks for working on this!

keep me posted
Ilene

[Ilene]

wait.. I stand corrected. Maybe you are on to something. I did have auto fade in/out in my preferences checked. I just removed that check... and rendered the section with the glitch. It was clean. YAY?!

I will forge on and keep you posted to see if this is an effective solution. Are you thinking there is a bug w that being check and therefore the audio file doesn't really fade out?

[cdoughertycd]

Trevor & Ilene, looks like I have been doing projects with the auto audio crossfade in and out checked.

I'll see if unchecking that stops the problem. Will try it with new concert job I have on Saturday.

Thanks both of your for pursuing this.

no... glitch is back.. auto fade in/out is unchecked... I added a 1 second fade ( automatically, just selected fade out) and the glitch was back. I adjusted the length, glitch is still there.

I removed the auto fade out, and just put a key on the audio file and faded down manually... glitch is there... no matter how long I make the fade..

ugh

Hi Ilene

I have tried many options to improve the sound including converting your MP3 to Wav
We are aware the some Mp3 using the Lame codec causes problems for video editors and always advise converting to Wav, but will use original and any problem data saved to the wav, so my tests showed the same glitches.
I have downloaded the files/video from YT and converted using Audacity to Mp3 although could have converted to Wav.
I have replaced the files in your sample Audio Glitch.vsp.

I will send the link to the One Drive Folder.
Can you try using these audio files?

[Ilene]

I orig only used wav files but had the same glitches w wav as mp3
I used to always burn my audio to a cd and then import/rip the audio files into VS from the cd --unfortunately even trying this didnt help solve the problem
I dont have audacity but I have tried and had some success just rendering the audio file as mp4, alone in a timeline and using that file

No fix is consistent... and just because it renders clean one time doesnt mean it renders clean another!! What i sent you is only part of the project. I have another 3-4 audio tracks to lay! The more you add to a project the greater the liklihood that you get a few of these glitches. It almost never happens on the first audio track.

Bottom line is still, what can corel do? THey thought they solved this before, they've done reaearch... they must come up w a solution?! No??

[Ilene]

Fyi... currently working w an mp4 video file that was from a corporate presentation -- the file was taken from the video camera, rendered as mp4 with the audio and video tracks embedded (but can be separated obv if i select split audio). I didnt need to separate for editing purposes, i just put a cut to grab a piece of it and tried to lengthen the fade out on the audio, just some applause and found the glitch present there too. So im not thinking this is an mp3 issue...
It's a VS rendering issue?

Hi Trevor: I was unable to replicate the end audio fade scratch noise, don't know why I'm not getting it today, maybe some Windows upgrade, who knows, but if I get it again I will post link to smart package of it.

The link below is to ongoing problem I've had that we've talk about quite a bit, the low gurgling sounds I get in a project (Pro X9) from MTS files from my Canon XA20. You can especially hear them here between 10-18 seconds. Although they are fairly faint I can hear them. This started with VS 7, VS 6 did not have this problem. This gurgling sounds does not occur when I play the MTS files with Windows Media Player outside of Corel VS, only hear them in a project and on render. To work around it I convert the MTS video to WMV, then share the audio from WMV to WAV audio file, then in a new project use the MTS for video and sync the WAV for audio. I'm not using WMV for render now due to it plays jerky but MTS does not. Sort of a multiple issue but please let me know if you'd like me to move this MTS issue to a new thread.

I've never done a smart project so here is link on One Drive, only excerpts. Please let me know if I shared this correctly for you to use. (Camera settings and venue not optimal for low light video unfortunately.)

Thanks, and apologies it's taken so long to get back to you about the MTS issue. Could be something not compatible with my computer and Corel re the audio MTS thing.

Unfortunately that vsp file you posted to One Drive does not contain any video. FYI in case you did not know, a vsp file is not a video file. It is a small text file which tells Video Studio what video is included in the project, where it -- and other files (photos, music, voiceovers) are stored), what filters and transitions may have been applied, and any other editing that has been done.

I'm afraid that for anything to be useful with your current problem, you will need to do a small Smart Package which contains the two MTS files in that VSP, and upload that to One Drive.

[cdoughertycd]

Hi Ken, I went to file then Smart Package, sorry I guess I don't know how to make a small Smart Package. Can you explain? Thanks so much.

Hi Candy
Have had the same difficulties creating SmartPackage before.

After playing around with Applause downloaded from the Internet, I have recreated your audio glitch (I think). It is a very short, sharp sound as if the energy of the applause is not giving up without a fight. To avoided it this is what I did:

1 Ensure the apply crossfade automatically is deselected from Preferences.
2 Create a Silence.wav file as suggested before. Drag the Silence.wav (or Silence.mp3) file onto a separate audio track (not the applause track) positioned such that it overlaps where the audio with the applause is to finish.
3 Click the Sound Mixer icon to show the wave forms and audio rubberbands.
4 Select the applause audio clip and insert an audio node (keyframe) at the point the applause has to start fading (Point A). Go to the end of the applause clip and select (insert?) another audio node and pull it down as far as it will go (Point B).
5 Select the Silence clip and insert an audio node at the same location as Point A above. If set up correctly it should be the start of the Silence clip. Similarly insert an audio node in the Silence clip at the same location as Point B.
6 Select the Point A node on the Silence clip and pull it down as far as it will go. This effectively applies a Crossfade manually.
It is more difficult to describe than do. You can shorten or ignore the Silence clip as you require after the Crossfade. Intermittent malfunctions are awkward, you can never be sure the workaround is 100%.

Hi Candy
Did you manage to take good images of the Milky Way?

The Smart Package as Ken said did not have the MTS file, we need this one.

Original file [H:\PSYCO 6-25-2017\20170624\20170624194406.mts]
Upload the to the same folder on your One Drive and we can relink.
Looks like a 10 minute clip, I think 1Gb + maybe a little large to upload?

I have a short test vsp on my one drive, the blip shows at the end.
https://1drv.ms/u/s!ApBs8FwBwJ5ji1KEHwAAcfue-Wes

the video clips on the top and overlay tracks (MP4 and M2T) are my rendered files of this project, clearly showing the blips at the ends. Sound Mixer and expand the timelines to view.
Remove those video clips, then render the MP3 and image file, see if you create those blips.

Hi lata

I'm lost with OneDrive etc, tried and failed.
So have PMd you with a copy of your amended project.
After rendering I do not get the glitch, your original so clearly showed. If you get the amended project you should note I have added the Silence.mp3 file to the end, crossfaded into it, using a slightly longer fade out than your original.

Your project gives a good example of the glitch that reproduces on rendering.
