Hi,

Other than what John EB mentioned, I don't see your J-cut. I see an overlap of objects on separate tracks. You should have audio and video on separate tracks. See the Bonus part (at about 12:30) of this tutorial to see how to make J and L-cuts:

and the second Bonus part of this tutorial where I added a bit about them:

Also, please learn how to take screen shots. This is not done by taking a photo of your computer. Look up how to do this; there are plenty of tutorials on it.

Hi Jordin and welcome to the Magix user to user forums.

First go your the programs setting under File / Settings / Program / playback and make sure the audio playback is set to wave driver. Then try the following

Buffer number set to 2

Multitrack size set to 8192

Preview size set to 16384

In the Video playback section make sure the Overload optimization for realtime playback box is ticked.

Press OK and see if that helps.

Ray.

@browj2
 

So i watched the videos and I did a Jcut and seperated the audio but it is still making the staticky sound during overlay. Still working on getting computer information over to John EB as well.

@CubeAce
I did exactly what you said and it oddly made the static worse then before...

Hi Jordin.

I can't see anything wrong with the video data.

Try the same sound settings but use one buffer. See if it sounds worse or better.

Also, how much physical ram do you have?

Ray.

@johnebaker
i hope these snap shots are okay because I was really confused trying to relay this info, and youll probably get more reliable info if i just give you the snapshots.

@CubeAce
It wont let me go further down to 1. It wont go any lower than 2.

And RAM is 64.0 GB.

 

@CubeAce

@Jordin-Mayo

OK. Leave the settings as I asked for for now.

I can't see anything wrong with the specs you have supplied either.

Next lets check the sound settings by right clicking the speaker icon in the task bar or finding it in the windows settings.

Next open the Sound control panel.

Check all settings are set to 24 bit 48kHz for both all recording and playback devices by clicking on properties and going to advanced.

Close and then open VPX 11 and try again.

There could be another cause but I would like to leave that until we check all your computer settings.

Ray.

@CubeAce Done. Still didnt fix it.

@Jordin-Mayo

Hi,

Looking at your image, you still don't have a real J-cut. You have the audio on track 2 overlapping the audio on track 4. There is no need to put the second clip on track 3. Do like I showed in the tutorials. For now, hold down the Alt key and drag the audio at the end of the first clip to the left to match the start of the audio on track 4. Then drag the second object up to track 1. Hold down the Shift key while dragging upwards to make sure that the object does not move left or right.

Does this work?

Here is what it should look like:

Of course, this does not solve the underlying problem.

Did you try increasing the audio buffer to 4 then 6? I have 6 in VPX13.

Did you try other video clips from other sources to see if the same thing happens?

John CB

@browj2 Hey John, I just tried video clips from my cell phone and they didnt have static when overlayed. How do I make it so my Canon M50 also doesn't have Static?? It had static when I just used the microphone from the Canon m50 camera, but it also had static with my brand new diety microphone connected to the canon m50.

@Jordin-Mayo

Hi Jordin.

This may not be your problem so don't panic but.

You may not be able to stop this if the camera is recording audio with a DC offset in its amplifier. That could be rectified if the sound track could be opened in an audio editor that allows DC offset correction but currently the Magix external audio editor or any external audio editor cannot be opened from within MEP of VPX. That bug needs fixing.

A re-install as suggested does not work and not worth trying.

When a sound file has DC offset it doesn't matter where the file is edited it will make a single click at the beginning and end of each end of the clip due to the sudden voltage being applied to the audio channel.

Where I have put Zero Voltage in the image above, Once opened in an audio editor, if it has a DC offset line showing parallel either above or below each of the two channels, that be can corrected in the audio editor if it has a DC offset correction function as shown below.

If this is not possible there may be another way around the problem.

On each audio track, enlarge the view until you can see the audio level line. At each end of each clip pull the line in towards the clip for a few frames. This will ramp up the volume and decrease the audio to zero voltage at the beginning and end of each clip and remove the clicks you hear.

This is not an ideal situation as the audio will still have DC offset when exported but if not much off zero should not cause any damage to any audio components.

Try this for clips that produce the clicks. If it works then the it's possible but not certain that the cameras' amplifier has a slight fault which will keep working but continue to produce these audio files or has a failing component.

If it doesn't work then the problem lies elsewhere and I'll have to think further.

Ray.

I turned down the volume on my camera and that didnt help the statick in my newest video im editing. Ill have to try what you said @CubeAce but man does it sound confusing to me. I wish I could just share my computer screen with you and you could do it for me haha.

@Jordin-Mayo

Hi Jordin.

When you play just one file in something like Film and TV or VLC player, does there appear to be any static or a click? When you hear the 'static' is it just one or two clicks, or more at each join? If it is one or two clicks only, then it most probably is a DC offset in the recording.

The other thing that may cause more disruption is if when mixing files from another source, files are recording audio at different sample rates but I'm not sure that would cause what you are hearing.

DC offset gives a constant signal in the audio which can not be heard as there is no wave form to produce any sound. Being Direct current (DC) it would make the speaker cones (or headphone driver) not rest at the same point as if they were not connected to any signal. Instead the cones are either pushed out or in constantly when there is no signal. They do not rest that the middle of the throw where they are supposed to rest. So when that signal abruptly stops or starts there is a jump in the speakers rest position producing the 'Click'. Another problem with DC offset is if constantly fed to a speaker cone at loud volume is it will heat the voice coils and if they heat up enough may become detached from the tube they are glued to or break like a fuse.

Again, that is if it is DC offset. It may be something else at this point.

You could upload a clip or two to Google drive or Drop Box for us to test the same scenario. YouTube or other hosting sites would be no good for this as the files must not be re-encoded for use.

One last question. Is it only happening with the J cuts with both clips from the same camera? If it is. then it is not DC offset.

Ray.

@CubeAce

1. Tried in VLC, no statick or click when played alone.

2. They should be at the same volume. I dont change the volume settings for different clips when I record.

3. Normally the clicking isnt just one click at the beginning, but more than one based on how long the tracks are overlapped for. If i overlap both tracks at the same time for a minute straight, it will click for that whole minute.

4. Yes, its only happening with J cuts with both clips from the same camera. If i mix it with a video from my cell phone, then it does not click.

5. Here is my dropbox link, hope it works!

@Jordin-Mayo @johnebaker

Hi Jordin.

The download works perfectly.Thank you.

It may take a while for me and and perhaps one or two others to see if we can get the same results as yourself.

At present, so far I can't see anything wrong with the clip during normal play.. The clip EXIF data looks normal which is as following.

[Edit] Ignore anything that was below this sentance earlier. I think I am wrong.

Looking at more data from your previous posts.

Will get back to you.

Ray.

@Jordin-Mayo @johnebaker @browj2

Hi Jordin.

The clip looks clean and well recorded. Can't find anything wrong with it at my end.

But looking at your earlier posts something is amiss.

This shot you took of the audio looks wrong.

SP/DIF is not the normal output we should be looking at for sound settings. It is an optical output,not the speaker output and still does not tell us much.

Please go to Settings / System / Sound, and on the right column click on Sound Control Panel.

When open, check the following settings are enabled and set to either 16 bit or 24 bit and not above and all have a sampling rate of 48kHz. I have posted a lot of windows together. You will get one window at a time. Use the properties box to get to the settings.

Then try again with your project and see if anything improves.

You have posted under Video Pro X but the screen shot looks like Movie Edit Pro.

Which one is it please.

Ray.

@Jordin-Mayo @johnebaker @browj2

Hi Jordin.

I can not replicate your problem using your, clip even mixed in with clips of my own recorded at the same frame rate and resolution and performing butt joined J cuts.

I would like to see if John Baker or John Brown can replicate my or your findings first but I can say with confidence that there is no DC offset on the file. That leaves me to conclude (for now) that if your system specs seem OK (which to me they do) then the fault may be down to.

A: Where the files are stored.

Ideally files to be used in a project should not be on the same drive as the program. Nor should the files be written back to the same drive as the program resides on. Putting the files on the program C: drive can cause bottlenecks in the processing chain with too much data transfer occurring causing various problems. The problems can vary from system to system and hard to pin down as to which bit is failing to work properly, but the cause is normally too much data transfer somewhere.

or

B: the sound card setup in either Windows or the program (or both) is wrong.

Check my reply above for the Windows sound settings. If your settings do not look the same as mine please post some images of what you see. Preferably larger images than the last ones if possible.

Ray.

@Jordin-Mayo

Again, did you try increasing the audio buffers to 4 then 6? I have 6 in VPX13?

John CB

@CubeAce Working on trying to do what you said to do in your first message before moving onto your second,

im afraid if i click "yes" is will screw up the current video i am working on. Will it? Or am i safe to click yes?

And...

thats what it says in the top left corner

@Jordin-Mayo

Hi Jordin.

If it doesn't work when you click yes then save the project with another name and exit. Then try the project again after reloading it to see if the alterations worked. If that doesn't work open the old project and everything should be back to the previous settings but that won't help your current problem.. It may help to take screen shots of each alteration you make and post here for us to double check.

If you are moving the files to another drive use the export project to another location method rather than just moving the files. That way the program will keep track of the files but move the files via that setting. It will copy the files to a new location for use.

Thanks for the second screen shot as your previous images were only showing one screen. Normally VPX has two screens side by side.

Ray.
