In VideoWave 7 I've been trimming mpg files to create a shorter video mpg file. The quality of the new shorter dmsm file is fine, but then I "output production as" an mpeg-2, 720x480 9mbs, dolby options and when I replay the new mpg in any player, the audio is very jumpy and broken, similar to what is playing on You Tube at this link:

(NOTE: the audio quality issue is not created when converting mpg to mp4 for youtube, the problem exists when I create the new shorter mpg from the dmsm and replay the new mpg in any player, Roxio or other)

Doing this (today) with some of my original mpg files results in ok audio quality, but (today) when using my most recent files the audio quality is bad after trimming and converting back to mpg from the dmsm.

I'm concerned about the Roxio program's integrity because the burn to ISO feature no longer works and at times I'll launch VideoWave, it appears for a moment, then it closes. I've had problems in the past with DVD Builder and no longer use that feature as was recommended on this forum. I do not use IE 7.

I've tried everything I know to isolate the problem, including updating my video card driver, disk defrag, doing this procedure on several different data files, any ideas why this audio quality problem would occur?

Thx, in advance for any suggestions. I'm reluctant to upgrade Roxio due to all of these issues and I don't need additional features, just a program that will do this procedure for me.

The first thing to try is going to Add/Remove Programs, and do a repair of the software. You do this by clicking on the Change option, not Uninstall.

Also, if you have Windows Media Player 10 or 11, you have to roll back to WMP 9.

Have you played with the audio card acceleration (through DirectX) and have you looked for new drivers for your audio card? I hope you are not relying on an audio chip in a desktop computer.

When you do rendering, make sure you are using software rendering. You didn't post computer specs in your signature so that's just a guess. In VideoWave, go to the top menu, select tools, then options, then put a dot near software.

Replying and troubleshooting your issues would be a lot easier if you would put your computer specs in your signature via My Controls at the top of the page.

Is software rendering an option in EMC 7/7.5?

No, Walt. DVD Builder, in EMC 7/7.5, always worked great for encoding, unlike the newer Sonic based versions.

I didn't think it did. So Steve should correct his post above, I have a feeling he thihinks this is the EMC 10 forum

You are correct about software rendering. I forgot where I was. I would edit my post but then these others would not make sense.

I deserve to be publicly flogged.

The other two items are still valid.

Oh, I think that we have all been flogged here, a time or 2, over the years.

No flogging here - but a round of whatever to all posters in this thread

It was YOU that stole all me beer!

[golinux]

What's "beer"?

[sknis]

What's "beer"?

That's a picture inside a Whole Foods Market. You may want to ask there the next time you go shopping !

There is probably an organic beer that does not use GMO but it may do some GOM'ing if you drink too much.

I have been boycotting Whole Foods for about 7 years as they have gone to the 'dark side'. That picture brilliantly illustrates one reason why I refuse to go there anymore.

Organic or non-GMO wouldn't make any diff to me. I have tasted beer maybe three times in my 66 years and gagged on it every time.

Back to the original problem.......

You probably already know that when you make the .dmsm file, it's just an editing file. When the program make a new mpg file, if the original file is encoded already ( as an mpg for example), the program has to decode then encode the video again. Sometimes errors creap in during the decoding and encoding process.

Some people have had better luck outputing the video to a DV AVI file and then putting that file on a timeline and encoding that new movie to the final format. ( It obviously takes more time, but sometimes it works.)

The other suggestions, doing a reinstall or repair, and changing the hardware accellerations are also good ones.

You might want to think back as to what hardware/software have been installed since the program was working correctly. It might be that something is interferring with the program. Also, check for spyware and malware that might be competing for computer resources (in the background where you can't see them) and you might try disconnecting from the internet and turning off your virus protection software when it's encoding.
