Seperating audio from video


G........

Question

8 answers to this question

Recommended Posts

The videos came from a digital camcorder. I'm not sure of the type of camcorder. They come to me formatted in MPEG. I am puting together a presentation from my church for a 75th anniversary. The main source of the videos comes from someone who knows even less than I. He saves them to his PC and copies them through his 'Roxio' (not sure which one) program. He says they play fine on his system. I have been getting messages about my Video adapter driver needing 'updating'. Where can I find out if I have the appropriate video/audio and/or display adapter? I was able see the problem with the audio when I captured it from one of the original videos. As stated previously, it was segmented and I just put it back together.

Thanks for your help,

Just because they play fine on his computer doesn't mean that they can be edited fine on your computer. And just because you get that update, doesn't mean that the audio is OK and that an update will fix it.

 

Lets' tackle that video card/chip first. Go to Windows Start, select run. Type in dxdiag then select OK.

When the window opens and gets the information, go to the display tab. One the left will be the identification of your video card/chip and on the right will be a driver number and date. Post those here.

 

You will need to update your video card/chip driver. We should be able to find an update for you. You will also want to update Microsoft's DirectX 9c here (link).

 

You could also update the drivers for your audio card but that is usually not required.

 

Call your friend and ask what video camera the friend has. Post that here also. Find out how the friend saves (transfers) the video to his computer and what he does to copy them to a DVD. Without this information, we are shooting in the dark. That digital camcorder could record the videos to tape, mini-DVD, full sized DVD or to a hard drive. In addition, almost all camcorder manufacturers have a proprietary format that may or may not be mpg. You and many of us will be less frustrated if you took a couple of minutes to make that call. :unsure:

 

Let's also back up a bit, why did you need to separate the audio and how did you know it was segmented?

Yes, you can extract the audio. In Media Manager navigate to the file and right click on it. Select extract, It will extract as an audio file that you can use elsewhere.

 

If you simply do not want to hear the audio in a Video project, just mute it; it cannot be deleted.

 

Look in the Tips and Tricks are of EMC 9 for the videos and watch the one about adding more than one audio file to a production.

 

Be careful with Registry Cleaners, the more aggressive they are about finding errors, the more they seem prone to cause problems. I have used System Mechanic 4 and now 7. It is a suite of clean up programs. It has a registry cleaner that has never given me problems but I don't use it unless I think the computer is running slow; then I run all the cleaning in that program.

 

Thanks for your help. I extracted an audio file (from a video) and I am seeing 20 second increments of no data (audio) between 20 second bits of data. Could this be corrupted from the original movie, something in the way they are being downloaded and copied or do I need to sacrfice a virgin?

Thanks, G......

OK I'm in the editor and cut the segments with no data. Guess what, the whole audio file is segmented! What gives? I can edit those files to their whole-some goodness but I would like to know what causes that(?)

I have no quick answers for you. Where did you get the videos? How did you get them on your computer?

There are others who are better with audio issues than I so maybe someone can jump in. I haven't seen this problem before.

 

What sound card do you have? Where do you have the acceleration set. - Just asking and looking for some clues. Of course I have to ask about how you are seeing the data skips. What does the actual audio sound like?

Is it possible to seperate the audio from video files in EMC 9 suite. I searched for this topic but may not have asked the question correctly. Also, what do you Gurus think of "RegCure".

We have about 1500 PCs where I work. Not a single one has a Reg Cleaner and not a single one has ever had any Registry problems…

 

Last time I used one was on a Win98SE PC. After restoring the Registry I uninstalled the program and baked it in my microwave! That PC runs 24/7 for almost 10 years now and hasn't a problem…

 

Why would I put my PCs at risk to use a program that really doesn't do anything?

I may have added more than you needed. I copied & pasted the info from "system information" and confirmed it from the DX Diagnostic tool I was directed to.

 

I will not be able to contact my friend until later tonight. I will then follw up on the other questions you have.

 

As far as the Segmented audio, I retrieved the audio from one of the films using the extract tool. Then from the editor I could see the segmentation. I needed to extract the audio to see if I could somhow salvage and make good what footage I had. I figured if I could take the video apart (literally) and put it back together using the editing tools. If nothing else, an exersize to help me learn the program more.

More info: The footage was taken with a "HandyCam 305" recorded on 8mm DVD. Downloaded into his computer with USB & "Nero Express 6 Ver. 1.8.1 for HC DVD" The format is MPG. He was duplicating his videos with a Roxio program. I get them in a MPEG format. I have'nt gotten which version of Roxio, or the utility, yet. Hope this adds to a solution versus more frustration for all.

 

As if this were'nt already convoluted enough, while trying to download my update of Directx 9c, I was unable to finalize the download due to a "Cryptographic service" request from the download. I have recieved another optional download (through Microsoft) and am trying it now. Also, I converted these videos to AVI format so my Roxio program could read them. But I am seeing inconsistancies between viewing the files in Roxio and Media player. The video and audio is scipping but in differant places depending on the player. I'm think'n this issue may be homegrown(?).
