In both VS 11.5+ and X2 Pro trial, if I select a clip in the timeline and right click, "split audio" is an option in the context menu. If I do a CNTL-A to select all clips in the timeline, then right click in one of them, "split audio" is grayed-out.

How do I split audio for all clips in one operation rather than one clip at a time?

I don't think it's possible.

Work around. You could create a new project in which you insert the first project (no need for rendering). The first project is being seen als one clip in the second project. Then you can split the audio with one take.

Hi

You can¡¦t

You can only split audio on single clips.

But why would you need to split audio???????????????????????

Imo splitting audio is very usefull. It gives you the possibilty to let the audio from one clip extend a bit into the audio of the second clip which gives it a natural flow.

No, it's not the same as fading audio.

I am working with 1920x1080 AVCHD and am getting audio dropouts on AVCHD DVD+R discs created from clips, even with no editing at all, where VS should not be re-encoding (I have selected the option to not re-encode MPEG compliant clips). Sometimes the problem is split-second dropouts and sometimes the dropout lasts an entire clip or more. I doesn't happen in all clips, just some, with no apparent pattern. I'd estimate that the drop outs only occur on 10-15% of the clips.

I discovered that when I play the problem clips in the timeline, even before doing a Create Disc, the audio drops out there too, so it must not happen during the Create Disc step. On a whim, I did a "split audio" on a problem clip, and when I played it in the timeline the audio was perfect. So I thought maybe routinely splitting audio on all clips might eliminate the dropouts that I am getting on disc.

I started another thread about these dropouts about a week ago. Ken Berry tried to help, but we were unable to determine the cause of the problem, other than a theory that perhaps Sony's implementation of DD 5.1 was somehow non-standard and VS was having trouble handling it. (The camcorder is a Sony SR11)

Thanks for the suggestion, I tried that and was able to do a split audio, however the audio drops out at the same point as in the original project containing individual clips. (See my previous reply to trever andrew regarding why I want to split the audio.)

Update: I had said that the video was unedited, but forgot that I had added 1-second fade-to-black transtions between the clips. I found that if I delete the transition immediately before a problem clip, the problem goes away. Then if I add the transition back between the clips, the problem re-appears.

There are fade-to-black transitions between all the clips (approx. 20-25 clips), but only a couple of the clips in this particular project have dropouts. So maybe the problem is related to transitions, but why some work and some don't isn't clear.

Strange. And when you export the project as an audio file. Does the audio file have dropouts as well?

Perhaps you could try the following. Export the whole unedited project to AVI. Than load this file in a new project. Let VS make the seperate clips and do your editing.

Hi dalemccl

I do not have HD but realise there have been problems with audio sync¡¦

Ken is the HD man.

Interesting that splitting audio corrects your audio problem.

As a workround, have you tried rendering the split audio clip, using same as first clip option.

This does not cure the original problem with HD clips, but may create a new one in sync¡¦

Many moons ago a sync problem with VS 8 was cured by disabling ¡¥Smart Render¡¦

I haven't tried exporting this project to a file yet, but will do so in a few minutes.

When I was having the problem last week I exported the project to an AVCHD file and then burned that file to disc and did not have the audio dropout problem.

If this consistently works, then it would be a workaround, but I'd like to solve the root problem, if possible.

I understand you want to solve this at the beginning. I haven't got a clue about the origin for these audio droppings.

I just created an AVCHD file and then brought that back into X2 Pro trial. The drop outs were still there when I played the file within X2 Pro.

Last week when I had the problem on a different project, and creating a interim AVCHD file solved it, I was using VS11.5+.

I have to think this problem is related either to the transitions or to my PC.

The PC is running Vista Ultimate 64 bit with SP1, August updates for DirectX, Intel Quad core Q9550 2.83GHz, 4 GB RAM, ASUS/ATI video card with the latest 64 bit drivers. No application software is installed except VS11.5+, X2 Pro trial, and iTunes/Quicktime which the X2 Pro installations instructions said to load (not sure why unless it is in case you want to create Quicktime files).

The weak point is the video card, an ASUS/ATI Radeon EAH3450 which is a low-end card (cost $30.) But as far as I know, the video card plays little role in video editing, especially regarding the audio.

I have another workaround!

Try crossfades with blackcolor clips instead of fade to blacks which seem to create the problem.

randazzo, thanks for the idea. I tried it and it worked!

I'll keep trying to figure out the problem with transitions.
