choppy preview/skips photos & audio
Howdy,
I am using Studio 6, NO HD video, and just making a basic slide show with some video and music as well. Most of the time when previewing (in auto preview mode, not ‘best’) the video is choppy, or it will skip audio, till the computer seems to catch up and will play normal for a few seconds, then hiccup again. And it really has a hard time showing a transition from one photo/video clip to another.Working on a Toshiba laptop, Pentium, 1.8GHz, 1GB ram. Yes it’s old, but I don’t recall having this problem so much before, some but not this much.
Now, if you have an idea, please explain it like I’m a 5 year old. If you only say ‘match the project properties to the output properties’, I won’t understand how to do this.
Thanks,
Rodney

What has changed since it was working smoothly? I’ll take a guess that you may be using a newer camera with higher resolution which is requiring more processing power to resize.
What is the resolution of the images you are using?

I would guess you are working with high resolution images….
If so, resize them to around DV resolution (720×480)
proportionately in photoshop or whatever you use to edit
your photos then save them in png format.
Also, are you sure you dont have some HDV video on that
timeline as well?Steve Rhoden

Thanks Steve, I will try and reduce the resolution of my photos. I am using them at 300dpi, what res should I shoot for?
Also, the video I am using is borrowed (with permission), and actually I used DVD Decrypter, which then makes it an IFO file, or a VOB. I know nothing about this, should it be a differnt type of file for editing? Should I first render the footage as something else prior to editing it?
Thanks for your help, glad this forum exists.

Hi John,
I replied to Steves post, have a look and add anything you think would help. Oh, ‘what has changed’ on my computer…much sadly. A coulple of fatal crashes, new/bigger hard drives, bigger programs (PS CS5, Lightroom, Google Earth etc.)
Thanks guys,Rodney

That explains why your previews are choppy.You said you have permission? then use Vegas
to rip the DVD instead, things would be much easier for you.Steve Rhoden

dpi is a photo term and has no relevance in video.
You need to find out the image size (in pixels) and adjust accordingly.
The basic rule of thumb in Vegas is that, unless you’re doing deep zooms, they should be no more than 2X your project resolution.
For example, if your project is standard def NTSC, your project resolution is 720 x 480.
Therefore, your images should be no larger than 1440 x 960.
If it’s HD, adjust accordingly.
IrfanView is a free app that will do do batch resizing very quickly.

Don’t worry about getting them to the exact size as close enough is good enough and Vegas will adjust them to fit the screen properly. -
As Steve and Mike pointed out, your photos don’t need to be any larger than 655×480 if you are not zooming in, or 1309×960 if you are. Use File | Import | DVD Camcorder Disc… for any DVD content you want to import, and you should be fine.
It’s important to note that laptops are inherently slower than desktops and 1.8Ghz does not tell the whole story. Laptop processors are graded like T4000, T6000, T8000, T9000 where a T4000 is only good for surfing the web and a T8000/T9000 is closer to desktop performance. If you have a 1.8Ghz T4000 you have an extremely underpowered processor for video work. But your expectations that it shouldn’t be slower than in the past is a valid one.
