VegasPro8 Mpeg and AC3 Problems

ScottCocoaBeach wrote on 9/11/2007, 6:58 PM

I just upgraded from Vegas 5 to Vegas 8 and installed Vegas 8 under Windows Vista. When I go to help and about then to components I see under MPEG that mcplug.dll is not loaded and under AC3 that ac3plugg.dll is not loaded.

Right after install (I uninstalled and reinstalled) when I go into Vegas for the fist time it will show these modules as loaded, however, even if I have done nothing other than entering and exiting the program - on all subsequent starts of the program I get the above stating the DLL's are not loaded. Thinking this may be a vista problem I tried installing under XP (I dual boot) and I have exactly the same problem. The drivers show as loaded but no longer show as loaded after the initial start of the program. The drivers do show as loaded on DVD Architect.

Any help would be grealty appreciated as my Panasonic Camcorder creates files with AC3 audio and I am getting no audio track with my clips due to this problem.

Thanks,

Did you install dvd architect? The actual AC3 encoder is in DVDa... Vegas just kind of borrows it when needed.

Yes I installed both - can you go into Vegas and go to Help then about then components and see if it is showing the MPEG and AC3 Dll's loaded? If I recall the versions that showed the one time in Vegas are different than in DVD Architect so I am wondering if that may be contributing to the problem.

Thanks,

Is this causing you a problem or are you just making an observation?

Reason I ask is that DLL's are loaded dynamically (Dynamic Link Library). Typically this means that they are not loaded until they are required. Thus, if you haven't done anything that requires the use of MPEG or AC3, they operating system may simply choose not to load them until required.

Yes - it is a very big problem. When I try import my files from my camcorder I am getting no audio track. I am using a Panasonic that creates MPG2 files with AC3 audio tracks. My audio tracks aren't showing up at all. I really need to find a fix for this or Vegas is pretty much useless for me.

I did some more testing tonight and sure would appreciate some other Vegas 8 users checking this - it takes about 2 seconds to do- If you just load Vegas 8 and go into help and about and then components and see if your mcplug.dll is loading and your ac3plug.dll is loading. Mine both say not loaded under Vegas 8 but show loaded under DVD Architect.

If I copy the appropriate folders from DVDa to Vegas 8 (under FileIO) then the first time I go into vegas8 the files show as loaded (the version numbers are different) for each program for some reason, but on subsequent loads they don't show.

Any help on this would be greatly appreciated. I have an older version of Premiere and really don't want to pay to upgrade it but may have to if I can't get this working. It's frustrating when Windows Movie Maker handles my camcorder files just fine but I can't get them to work with Vegas.

Thanks!

mine both say not loaded in v8

and in dvda they both have a path so loaded I'm guessing

edit same with v7

Mine also says "not loaded", but I'm having no problems at all with production.
Any other tests I could do to help you?

Vegas only loads them when they're used, not before. Has NOTHING to do with your stuff not opening as I can open video in mpeg-2+ac3 off a DVD no problem.

What camcorder uses ac3 files? Is it a DVD camera? If so you'll want to use file - import - DVD camcorder disc.

I've done it before & it works fine.

No vegas loads them up until use. The only interesting things is that Vegas 8 no longer puts those in the shared plugins folder so they're exclusive to Vegas 8 & DVDA 4.5.

I use the Panasonic: SDR-H200
3CCD Hard Disk Drive/SD Palmcorder® Camcorder with Optical Image Stabilizer and 10x Optical Zoom, records to 30GB Hard Disk or SD Memory Card

It records in MPEG2 format. The included software allows the creation of a DVD disk so maybe I can dump the files to DVD and then get them to import with audio, I'll give it a try. I tried using the import from DVD or Hard Drive options and it wouldn't let me open anything or select a folder so I think it is looking for a different file types. My extensions are natively a .MOD extension or MPG if I use a conversion utility that also fixes the widescreen flag.

I can bring the native files into Windows Movie Maker and they work just fine.

Thanks for the suggestions.

I was just looking around in the Panasonic software and the audio format for my files is listed as Dolby Digital, 2 Channel, 48.0 KHz, 256Kbps if this is helpful.

Thanks!

My Vista 64 says:
mcplug.dll version: Not loaded
ac3plug.dll version: Not loaded

After loading an MPEG from a Sony Hardrive camcorder (SR7 I think?)
I get this:
mcplug.dll version: 2.0.0.3875
ac3plug.dll version: Not loaded

Properties on this MPEG clip show the following:
Video: 00:00:06.120, 25.000 fps interlaced, 720x576x32, MPEG-2
Audio 1: 00:00:06.240, 48,000 Hz, 5.1 Surround (stereo downmix), Dolby AC-3
Audio 2: 00:00:06.240, 48,000 Hz, 5.1 Surround, Dolby AC-3

On the MPEG clip above I'm getting audio and video with no problem.
I'd assume you were not using VIsta for V5 and you are for VP8 .. I don't know,
but I'd check what codecs you may be missing for the audio to play. Something's
is clearly missing or in conflict on the Vista partition but it doesn't sound like a Vista problem.

Sorry. That clip I quoted in previous post came from a Sony DCR SR100E camcorder.

This sounds more like you used USB to transfer your video. The only real way to get a good transfer from your camera is to use Firewire. USB does not work well with Vegas or almost any good NLE
USB usually does not bring in the audio, with Vegas
If your camera doesn't have a Firewire IEE1394 port, there are stand alone units that will do it. (Canopus, ADS, and others that will take your camera analog outputs and convert to firewire)
Editing in mpeg format in also not easy.
Maybe Windows Media Encoder will let you edit

I'm having a similar problem. I have a new SONY HDR-CX7...and I'm transferring MPEG2 files directly off memory stick (it's an HD camera, but I'm shooting SD video).

If I shoot in HD, the *.MTS files import audio and video. However, importing MPEG2 files imports video, but no audio. Interestingly, in Vista32 I can play the MPEGs with video and audio in Windows Media Player...however, the audio just won't import in Vegas.

Is this different than what other are reporting? It's really frustrating.

**Update**

I experience the same problem with DVDA 4.5 - I can import a file, but there's no audio.

For the heck of it, I tried importing an MPEG2 into SF9 - and, interestingly, it's the same problem. So, is this a VISTA issue, or a SONY issue? Vista can play the files, SONY software just can't do anything with it.
