Vegas Pro 13 on new machine

Percepto wrote on 11/8/2014, 11:06 AM
I have just bought (what I consider to be) a top spec, custom-built laptop to edit video.
I installed Vegas and put a random MP4 file (no audio) in just to test it.
I cut the video up into 6 parts and layered them on to 6 different tracks.
I then resized 5 of them so that there was a video playing in each corner, 1 in the middle and one as a background on the screen.
I expected my system to handle this easily but the preview is slow and stuttering, even in Draft mode.
Is there something I am missing, a setting I have to change?
Thanks in advance for any input or advice.

Thanks for including your system specs since you asked a question about system performance.

In spite of your expectations, the project you devised as a test demands the hardware and software decode, resize and preview five or six simultaneous streams of potentially highly compressed video. (You didn't give specs on what's in the .mp4). You may be asking a lot from a mobile processor and video adapter.

Thanks for the reply.
It is a 45 sec MP4 at just 8mb.
It's not even HD footage.

1) Does the preview run at full frame rate with one track?

2) Mute one track at a time until you get full frame rate?

Ok, something is definitely wrong!
I just re-opened Vegas and dropped the original file in (no resizing and just 1 track) and it is stuttering and even the cursor and time clock are sticking every half a second.
Yesterday when I first opened the file it ran perfectly.
Any ideas?

Update.
I unplugged my external soundcard (RME Babyface USB) and the video ran normally again. Does anyone have any idea why this could be causing a conflict?
It is still struggling with the picture in picture test that I tried but it seems that I had false expectations from some of the replies on here.

You said the mp4 files had no actual audio. Can you post the mediainfo output for the files? Where did they come from?

Have you tried an MP4 with actual audio?

It is just a short MP4 which came as part of the Sonar X3 content (test video file for video scoring)
I haven't tried a clip with audio, this was the only video file on my laptop as it is brand new and I have only installed Sonar & Vegas.

Frame Width 720
Frame Height 576
Data Rate 1500 kbs
Total bitrate 1660 kbs
Frame Rate 25 Frames/second

How about the codec that was used to create the MP4? Both audio and video?

How do I find this info?

dxdy was earlier referring to an actual program called Mediainfo. Open your file with it, choose View > Text, and you'll see all the info including the codecs and encoding settings. You could copy and paste all that here.
