Desperate for audio help

JackW wrote on 1/4/2012, 1:23 PM
I purchased a Datavideo DN-60 recorder not long ago and am stumped by an audio

The unit records beautifully -- AVI files -- and files, downloaded from the memory chip to my computer, play back with video and audio in Sony Movie Studio. However, if I attempt to bring the same files into Vegas Pro 8.0c there is video but no audio. If I render the files as AVI in Movie Studio they play perfectly in Vegas.

I don't know whether this is a codec problem or what, but I'm in the middle of a month long shoot and would really like to be able to edit in Vegas rather than Movie Studio, and I don't have time to bring files into Studio, render and then import to Vegas.

Any suggestions will be greatly appreciated. Meanwhile, I'm pursuing this with tech support at Datavideo as well.

Please post full details about your original file using MediaInfo (from Sourceforge).
As you indicate, it's probably just a codec.

I have both VMS and vegas pro 9. If you have a short clip posted somewhere I can try to duplicate the problem.

Is your memory chip FAT 32 or NTFS?

[EDIT] I see it is DVCPRO, which "may" not open in Vegas Pro 8.0c.
What version of Vegas Movie Studio are you able to open it in?

[EDIT2] Here's the issue: Specs for your device say "DV25, DVCPRO25, HDV."
If connected to a standard DV camcorder via firewire, you should select DV25.

Musicvid: Thanks for your help here.

In answer to your question, I can open the files successfully in Movie Studio 10.

However, the only choices in the setup menu for the device are
1) AVI (Microsoft)
2) AVI (Canopus)
3) MOV
4) MXF (OP 1A)

I've been capturing from a PD-150, via Firewire, using the AVI (Microsoft) setting.

So far the device works as advertised. I've been transferring the files from the flash card to Movie Studio 10, rendering to an AVI file and bringing the newly rendered AVI file into Vegas 8c, which adds a few minutes to the process but is an adequate workaround for now. I'd still like to be able to import directly into Vegas, however.

Thanks again for your helpful suggestions.

AVI (Microsoft)

These are all the same thing

There are two types of AVI files; Type 1 and Type 2. (Not to be confused with OpenDML AVI 2.0 files, which allows AVI files to be larger than 2 GB.) The main difference between the two is how the audio is stored.

Read the section, "DV AVI" in the following Wiki:

It sounds like the Datavideo is producing Type 1 files and Vegas Movie Studio will handle them. Unless something has changed recently, I believe that Vegas Pro will only handle Type 2 files.

There are several free type 1 to type 2 AVI converters around, eg

Thanks musicvid, John and Peter. It hadn't occurred to me that the files might be AVI type 1.

I'll try the converter you suggest and see if it works. It may well be that rendering to AVI in Movie Studio 10 is doing the same thing. Unless the ULead converter is faster I might just as well stay with the Movie Studio to Vegas work flow.

I'll also contact Datavideo and see what they have to say about this.

You gentlemen are always helpful and I appreciate it very much.

You may be re-encoding the video if you go via Movie studio, although re-encoding DV is not so bad as MPEG. I understand that the Ulead tool doesn't re-encode.
