If you would like to help test the pre-release HDV reader for Vegas Pro 8, please follow these exact steps:

1) Download the file "M2tsplug.zip" from this ftp site:

ftp://md-ftp.sonycreativesoftware.com

username: scsdev

password: oh7e2McT

2) unzip

3) copy the file

m2tsplug.dll

into (default path) C:\Program Files\Sony\Vegas Pro 8.0\FileIO Plug-Ins\m2tsplug .

Choose yes when prompted to over-write.

4) Restart Vegas> Load up any HDV files or HDV projects you have been having trouble with.

5) Please post your results back to this thread. Don't start another thread.

6) If you run into problems, please post details. Critical details are

a) full system specs

b) problem file genealogy

- What device recorded this file?
- Was the tape brand new, or was it used once or more?
- What application was used for capture?
- Has this file been opened or saved in ANY other application, such as Womble, or Premiere.
- What problem did you encounter (stability, red frames, black frames, other)

The more detail the better.
.......
Please limit your comments in this thread to HDV file problems only. This beta HDV reader does not change the behavior of other source file types, it is for checking HDV .m2t files only.

If you run into a problem with this new reader, please delete this file (m2tsplug.dll) and un-install/ re-install Vegas Pro 8.0b.

Do not contact SCS tech support about this pre-release HDV reader for Vegas Pro 8. This needs to be thought of as a component beta test between you, and SCS engineering.

Good luck, and we look forward to your results.

I hate to be the bearers of bad news.... but I've got a Vegas lock up on trying to build peaks for a m2t file. I tried it several times. Every time it reaches 10% on building the peaks and freezes.

This is with the patch DLL.

Please advise.

Followup....

The problem has definitely been introduced with this patch.

I went back to the original DLL. I got my favorite WRITE ACCESS VIOLATION exception when it was filling in the video frames on the timeline (which is thankfully no longer happening in the patched version). But the peaks calculation worked fine in the old version.

This is a new capture. It's about an hour and 10 minutes of video. Two clips hang solid on building peaks. One at 10% and the other at 54%. Precisely repeatable. One clip is ~200MB. The other one is a bit larger. All other clips in the capture build the peaks with no problem.

I can ftp the clips if you like.

try running Mpeg2Repair on the file(s)

What needs repairing??? It only hangs when I run the Vegas patch DLL. it doesn't hang when I revert to the old DLL. How can that be a bad media file?

I fail to see what we are accomplishing by saying the way to fix Vegas hang problems is to download some third party tool and try to filter a perfectly good m2t file into something that won't upset Vegas. Is that the way we want to accept a professional editing product?

SCS put out a patch to see if it works and asked for reports. It doesn't. work, and I'm reporting. Something else needs to be fixed, and it's not my media files.

I played both clips with no problem in Windows Media Player.

Back on the patched version of Vegas, I succeeded in stopping the peak building before it had time to freeze on one of the two clips. I decided to just play one of the clips on the timeline. It played fine, video and audio, until it hit the same spot that it was hanging on the peaks earlier. At that point, video and audio stopped and Vegas froze up again. Had to use task manager to kill Vegas.

Very reproducable. SCS... please email me. I can assist in debug. Or I can send you the clips.

Obviously, there is a problem with the files themselves. I'm relatively certain that MPEG2REPAIR will fix them. Personally, I'm glad that Vegas won't load files with problems although I suppose that Vegas could handle these files a little more gracefully.

I think Mr.2G has got it right if they work in the unpatched version, but not the patched version there is an issue with the patch. Whether it's a showstopper or not is up to SCS.

Telling someone to change the conditions of the testing by modifying the media with a different program like a MPEG2REPAIR completely invalidates the test in question. The patched version introduced an issue that previously Vegas handled ok.

No one should ever have to be running a tool like MPEG2REPAIR to keep Vegas from flipping out.

Well, Mr. Bigrock, the files apparently didn't work with either the release version of the .DLL or the beta version. In neither case did the files operate correctly, they just exhibited different problems with each .DLL.

If MPEG2REPAIR can make them usable, then I'd say, go ahead and fix them.
