      Hello everyone,

      I am making the leap from SD to HD, just gotta buy the right camcorder. Anyways, I have been tinkering with HD editing. Doing some practice stuff and now I have a simple question with I hope a simple answer.

      In SVP 9.0 I have imported some native HDV footage (1440×1080) and the project properties are the same (1440 x 1080). It all looks great. But just for fun I imported some SD footage (720×480). I expected the SD footage to take up a much smaller portion of the screen. It looks like the native 480 pixel height is now at least double. What is going on here?

      Vegas automatically scales all stills and video up to the project properties settings.

      If you want to keep your SD footage at the original size, open up the Pan/Crop window and resize it there.

      I have a dog.

      What do these things have to do with this thread, eventvideoguy?

      Well, I guess that means that Vegas essentially “blows-up” SD to at least 2x it’s original picture.

      I’ll try to do the crop/resizing thing and keep all SD video on a separate video track so I won’t have to resize each clip.

      Thanks again,

      Simple answer is:

      SD video is 720×480 pixels. Your native quality is 1440 x 1080. This is 4 times better quality. (2 x 2) What is the software do in the back? It is use your SD and blow up to 2 times factor a specail algorithm do this and place like antialiasing function producing an appreciable quality. Some paint program do the same, blow up a factor 2 and scale down a factor of 2 the picture looks great we call it INTERPOLATION .

      Playing around with Vegas tonight and 720×480 superimposed on a 1440×1080 screen size does look a tad small. Probably a good thing that Vegas resizes the SD.

      Your explanation signmax does help. Thanks.
