HDV users: please read

The new reader DEFINITELY slows down project opening. But my preview seems to be a bit more sluggish... Are others finding this too or is it just me?
bruceo wrote on 7/29/2008, 1:46 PM
Yep, very sluggish. We are now able to open numerous projects with Sony CF recorder files and work and render them with no probelm (REINFORCING the fact to the fanboys that it IS NOT a CF card or harware issue, but the video buffer & mpgdecoder problem)

But now all projects eve ones with regular HDV captures are very sluggish due to poor thumbnailing efficiency. So now we have gained in tolerance but lost in efficiency with TERRIBLE frame rate previews.

To me it seems that the new reader is very similar to the old 7d reader: less prone to crash on errors, but noticeably slower on previews. I'm thinking about writing a simple batch file to swap the reader files out. That way I could use the regular 8b reader except when I was having difficulty with crashes, black frames or Vegas disappearing during renders.

Well, let's try to avoid forgetting that this is a Beta and not written in stone. Hopefully Sony will pick up on the fact that it slows down preview and will adjust accordingly.

Sound great, please include me in the update

I have noticed no slowing down in preview frame rate. Still getting full frame rate 29.97 HDV 1080-60i previews at best/full quality on my Dell laptop.

Ray, you're going to have to include yourself, the instructions and a link to download the update are contained somewhere in this thread. It's your job to find it.

Where do you live? I would like to come see for myself. 3 shops with 6 installations on different machine configs and all very capable and all exhibit significantly reduced playback performance, but no crashing. 3 steps forward, 3 steps back, but at least there is some effort so far. I just think that it has been too long in coming and should be TOP priority 24/7 for reliable and efficient HDV editing.

Here is a TEMP FIX to the problem.
TEMP FIX FOR *.M2t files in SONY VEGAS 8.0

The problem is if you have more then 30+ clips on the timeline that are *.m2t files Sony will give you an error. I have a temp fix below. Enjoy!

1.Add up to 30 *.m2t clips to timeline.
2.Save project. (Make sure you save as a HDV project)
3.Start new project, refresh so that the project you saved will show up in explorer in Vegas. (Make sure you start a HDV project)
4.DRAG-DONT OPEN the saved project to the timeline. Vegas will auto render a *.veg.sfap0 file, this will save you lots of time redering *.avi clips like Vegas website says to do. You can have AS MANY *.veg.sfap0 files on a timeline as you want unlike the *.m2t files. Please email with concerns or if you cant get it to work.

HOPE THIS HELPS YOU ALL OUT, I know it did me! -Joshua

Just curious, and to bump this important thread:

+ ForumAdmin, how is the beta test going?
+ Have you already had enough valuable feedback to iron out the quirks in the beta?
+ What is your current estimate - when is 8.0c going to be released?

I would like to be added to the list also

Terje wrote on 8/3/2008, 4:33 PM

I wonder, are people like UFM slow or lazy? Given that there is a huge number of posts in this thread telling you that you do not have to be added to any list any more, all of them showing how you can get access to this software, how can it be that people still don't get it?

Sorry, I just can't abide lazy people.
Tim L wrote on 8/3/2008, 8:42 PM
The problem is, the first post in this thread asks people if they are interested in testing a beta version of the HDV reader, and the next 70 posts (approx) basically say "Yes, I would", "Count me in", "Add me to the list", etc.

Those of us who have followed the thread since the start know what the deal is, but we probably can't be too hard on people who give up after reading basically the same thing for 50 or 60 or so posts down and then decide to add their own "count me in" request at the end of the thread, rather than discover the goldmine hidden on about the 74th post.

It would probably have been better for ForumAdmin to update the very first post with instructions on how to get the download -- would have saved a lot of trouble. But... its fantastic for Sony to have done this beta test regardless.

I am curious if there will be any more versions of this DLL released. If not, can we asssume that we now have Vegas 8.0b.a? LOL!!!

Thanks and impatiently looking forward to the rest...

I didn't see this problem mentioned in the posts, but maybe somebody out there has the same problem with the new .dll

After I replacedgo very slowly it, every project I open tries to re-build its audio peaks. They all go fast for a second, and then slower and slower till about 10 seconds in Vegas no longer responds. If I cancel that process before it crashes and then rebuild audio peaks through the view menu it happens instantaneously.

This happens EVERYTIME, in both XP and Vista 64, on the same system.

System Specs:
Intel Core2Quad 2.66 GHz
4 Gigs RAM 2.67GHz
Gigabyte DS3L motherboard
Onboard sound
GeForce 8600

To "kairosmatt":

I had a problem with an HDV project that was mostly complete using the old .dll file and XP. When I switched to the new .dll file, the
peak-building would get to 99% and stop (although it did not slow down before that point). Nothing I did would cause it to complete the building. My only solution was to try to finish the project and export the video with the old .dll file and then fix the results the best I could
using "Mpeg2repair" on it - and then also reimport the video into a new project after installing the new .dll file and fix a black frame by exporting the frames before and after it as stills and placing one over the other at 50% transparency to replace the black frame in the video. I could also have used the original footage (if that was not the cause of the problem...), making sure the filtering was the same for the replacement frame or short clip.

Thanks for the post-sorry to hear that you are having the same problem, but at the same time it makes me feel a little less like pulling my hair out!!!
I just keep canceling the "building peaks" and continue to work. As long as I'm sure to cancel in time, my system is very noticeably more stable with the new .dll. I am used to the visual cue, but I can live with out it.
If I read in between your line correct, a new project with the new .dll does not have this problem?
DRuether wrote on 8/7/2008, 9:24 AM

To "kairosmatt":

Correct (I thought I made that clear.....;-).
The new .dll on new projects has solved all my problems editing HDV in Vegas Pro except one minor one - it will not correctly auto-split scenes (I use HDVSplit for that and import the resulting clips).
FilmingPhotoGuy wrote on 8/8/2008, 11:02 AM
I tried the new DLL and am not happy with the results. Guess what! I never made a backup of the older DLL. Could someone please put it up for download somewhere.

I will report on my findings as soon as I have done a comparison between the two.

If you send me an email through my profile, I'll attach the original .dll and send it back to you.

Currently on a boat in Tonga Bruce. Come on over! But really, I'm shooting/capturing/editing tons of HDV on a daily basis here and I'm getting 29.97 all the time. It's just not an issue for me. I generally edit with a half-size preview window but it's set to "best (full)" and I have "Scale video to preview window" checked.

However I got another one of those m2t files with dropped frames that hung Vegas using the new .dll but could be opened and salvaged by using the older .dll and working around the red frames.

I think this thread deserves a big BUMP!!!

I quote DH from SCS:

" This forum is the place for us all to communicate about it. We look forward to working with you, we want to get this right for you, stay tuned and we'll make this available very soon."


I think we now finally deserve an update from SCS. It does not help to stay "tuned" if there is no "transmission"...

Many people have contributed and tested the new patch, mostly with good results. Is the testing still continuing? When is 8.0c going to be released???

We - the loyal users - have been communicating a lot.

SCS - now it's your turn!!! Please!

I have an old copy of Vegas on my computer but I use Vegas Pro 8 for work and have been having trouble entering the .m2t files it generates into the timeline. Could I help test the software? I'll take what I can get to help me reach my deadlines.

count me in

Jtansek2 - please read before posting, the info was about 1/3 of the way down.

I'm posting it at the bottom again so that we can reduce these posts.

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:


username: scsdev

password: oh7e2McT

2) unzip

3) copy the file


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.

SCS dev"


now, we'll see how long it takes for this to get off the screen and people to re-request the info. (wish the forum admin would put this in his post at the top).
