I just have similar problems, even with the latest Vegas Pro 12.
However, after an incredibly quick reply from Sony Support, I managed to fix the problem and would like to share the solution with you guys!

Problem:
I am trying to add two media files to the project. Adding the first media file goes ok, but as soon as I add the second file, Vegas hangs. Strangely, changing the order of the two files results in the same behaviour, so I would the problem to lie not in the compression in the files.

I have attached the media info of the video files, that were created by Handbrake (opensource compression program). The settings for h.264 are: ref=1:weightp=1:subq=2:rc-lookahead=10:trellis=0:8x8dct=0. Constant 25 fps, 1280×1024 pixels.
Problem does also occur with other video files (also processed by handbrake).

When I try to add the original files (h.264 inside AVI container), Sony goes wild as well and hangs…

Actually, I seemed to have this problem with ALL video file I added to the project.

I got the following answer from Sony, that completely resolved all issues for media import!

Answer Sony

Hi Rob,

Thank you for contacting Sony Creative Software.

As a troubleshooting step, please navigate to C:\Users\**username**\AppData\Local\Sony\Vegas Pro\12.0\Media Pool Thumbnails (where **username** is the actual account name on your machine) and delete the contents of the folder named: Media Pool Thumbnails. Then restart Vegas.

The AppData folder is a hidden folder.

Sounds interesting Dave.
Remember from the old days (when disks were still really slow) that I set up a ramdisk.

– Can you give some numbers on performance changes?
– Does the editing feel faster/more responsive?

Thanks for your 50 cents.

[Rob Wijnhoven]

Interesting. How do you use the ramdisk?
– To read the input video files
– To store the compressed output video
– Other?

I use an SSD to store the source material (and save the render), but the actual editing feeling is exactly similar to reading from a recent harddisk.

[Rob Wijnhoven]

My 20 cents.
Using Vegas 11, Core i7 2600k, 8 GByte and Windows 7 Professional.

Dynamic RAM: 0 MByte –> render time 3:00
Dynamic RAM: 1000 MByte –> render time 3:08
Dynamic RAM: 2000 MByte –> render time 3:08
Dynamic RAM: 4000 MByte –> CRASH
Dynamic RAM: 6000 MByte –> CRASH

Love to see the most unstable of Vegas Pro ever released 😉
But anyway, there is not much difference, perhaps they fixed some bugs.
Strangely, Vegas actually uses all the dynamic preview memory while rendering.
Although it does not seem to need it (at least for the system I have), and for most people it seems to work against performance…
Very strange!

If you want to deinterlace your video, I recommend to double the framerate.
Basically, every field is then turned into a complete video frame.
An interlaced source of 50i (50 fields/sec) is then turned into 50p (50 frames/second).
Motion video becomes smooth, compared to the motion jitter when sticking to the original framerate (25p in this case).

I wrote some text on my website, all can be accomplished with free, opensource software.
Most easy to do in linux, but the article I wrote explains how to do it in Windows.

I noted however, that it is a bit tricky to convert existing projects.
Replacing the originally deinterlaced videos (25p) with the new 50p videos resulted in strange artifacts.
Then I noticed that the project settings were still on 25 fps.
Put them to 50 fps, and resulting video is super smooth.
Note however, that the effects have some trouble when changing the framerate.
I had to adjust EVERY titler effect I used (the NewBlueFX titler).
Updates to the project framerate are not passed to the effects apparently.
Anyway, just start new projects with the new, correct settings, and you are good to go!

[Rob Wijnhoven]

Quite annoying that there is absolutely NO version information on the website, plus no email notification.
Users like us just have to guess that new releases are out.
Not very userfriendly…
Anyway, every bugfix is welcome 😉
Had several crashes and annoying ‘features’ so far.
Although the plugin is amazing!

Hey guys,

I did a quick performance test on Sony Vegas Pro 11, to see the effect of the GPU acceleration on a Nvidia GTS 450.
