Activity Forums VEGAS Pro Image quality

    I’m an amateur been using Vegas and have recently faced an issue I hope that you kind people of the forum can help me with. I have had to prepare a multimedia clip (video/digital stills/audio) to be displayed thru DVD onto a 52-inch LCD TV (used Sony DVD Architect to burn the DVD at PAL settings 720×576).

    I rendered the Vegas project as an AVI file and I didn’t change the image resolution (Nikon D300, jpg format @ 300dpi), but the images look like crap with artifacts popping up .

    What have I done wrong?

    There is no need to have the jpeg image at 300dpi. 120 or 72 is fine for dpi settings (less taxing on teh computer) and you won’t benefit from having 300dots per inch for television viewing.

    Now, are you zooming in? If so how far? Make sure your picture resolution is at least double your project settings if you are going to be zooming in up to 50% or else you will get artifacts.

    Also, turn on reduce interlace flicker can help (right click the picture on the timeline, choose properties, and choose the checkbox for flicker) in reducing a strobe-like effect).

    Does the rest of the footage look fine (minus the pictures)?

    To expand on Jeremy’s comments, dpi is a print term and has no relationship to video terminology.
    The only thing that matters here is pixel count.
    My guess is that these images are rather large in size (on the order of 3,000 x 2000 pixels or even larger).
    What you need to do is, as Jeremy suggested, reduce the image size.
    IrfanView (an excellent and free program) has a batch resizing utility that is extremely fast.
    Unless you’re doing deep zooms, your images should be no larger than 2X project size which, in your case is 1440 x 1152.
    Use IrfanView to resize them and I’m positive you’ll get the results you want.
    If there is still some shimmering afterward, apply a very slight Gaussian Blur to the problem images.
    Set Horizontal to 0.0.
    Set Vertical to between 0.001 to 0.003
