Vegas 3.0 Problems

Just tried 3.0 and am having trouble with the image on the timeline, it is "bleached out" with a checkerboard pattern incorporated in it. If I have 2 video tracks the preview window shows a composite image of both as if you were doing a cross fade. The opacity is 100% on both and alpha is set to source on both, both are parent tracks. Also on a previous attempt the video preview window would only display correctly at a small size, small that made for blocky image. Any ideas. Thanks

Just found that if you go to media pool and click on properties, the alpha channel was set as premultiplied. Changed it to undefined and now it's fine. I'd like to know how to change it so this isn't the default. Everytime I drop a clip it has premultiplied alpha and must manually be reset to undefined.

Where did your test files come from (what created them)?

Anyway, yes, no problem to turn this off. Right click on one of the problem video events, go to media> alpha channel, set that to none. Then click the stream properties save button and all files that match the problem event will now be interpreted with alpha channel off. If all the problem files are exactly the same, this will be a one time operation. If they of mixed attributes you may have to do this process multiple times. This info is saved in "vegas video profiles.ini", in the Vegas installation folder.

The first clips were captured with VidCap2.5 and I have just now captured 3 clips using 3.0's capture, then set stream to no alpha but all the clips need to be reset to alpha= none to appear normal on timeline. Is there any reason a clip that's by itself on the timeline with alpha set at premultiplied appears with the checkerboard effect. I just want to capture video as before and drop it on to timeline without any trouble. I love Vegas and have learned alot about it's use although I will admit I don't understand the Alpha and some of the mask capabilities, just haven't gotten that deep yet.

Try turning the "ignore 3rd party codecs pref" to "on" (checked). You likely have a 3rd party DV codec that is at the root of this. Bonus: you'll be sure you are using the new SFDV codec.

Let us know if you still see the problem-

That seems to do the trick. Thanks for the help.
