Hi Norman,

If you go to OPTIONS-PREFERENCES tab EDITING, then at the bottom you can increase the value (from 0-100) for the default smoothness value of keyframe interpolation in the pan/crop window.
This is not exactly what you are asking for, but it is the best I can think of.

Here you find more on straight and premultiplied alpha channels in photoshop:

I think it’s time for other peaple to speak also, but I absolutely wouldn’t be surprised if your problem is caused by the fact that you are editing an MPEG4 file. This usually doesn’t work well.
Ofcourse you can try to convert it to a format that likes to be edited, but this will do no good to the quality of the output.

‘I’m glad Theo’s suggestion worked for you too.
Im still puzzled though as I never have to do that.
I drop it on Vegas and it works, no playing around necessary.’

Hi Mike,

I guess that it has to do with the type of alpha channel (straight or premultiplied). When you make effects in Particle Illusion, you see that there are many options (things that can go wrong) when you create an alpha channel in the output. And in those cases I always have to select manually in Vegas the type of alpha channel.

If your PNG file contains an Alpha channel, then place it on the timeline of Vegas, right click on the event, select PROPERTIES, go to tab MENU and select from the alpha channel pulldown menu the right option. If you don’t know which option you need, just try to see which one works best.

(JPG files never contain a alpha channel. For PNG files you have to make sure you create it with alpha channel. If you are not sure, place it on this forum and we will check for you).

All MP3 files are different in the way of compression etc. So it is known that not all MP3 files can be handled by NLEs (this is not only the case for Vegas but for most (all???) NLEs.

Why not just using this effect on its own track?

if you really don’t wanna do that, you can use keyframes to bring everything back to the begin situation. The easiest way to do that is by copying the first key, which is present before you start and paste it somewhere on the timeline of the trackmotion window at the position where you want your effect to be normal again. However, you can not make the track a source alpha track again without losing your 3D effect.

Another way to have everything on one track: Create a new project where you perform the 3D effect and import this .veg file on the timeline of your main project. Then you will have everything on 1 track.

So that looks OK. What kind of files is your footage (DV-avi, MPEG4 etc?) Did you only do masking? Or also other types of effects? Did you do the masking with the event pan/crop tool? Or did you make your masks on another way?

And you pressed the “television icon” on top of the preview window?

Did you create an AC3 file in Vegas before bringing it into DVDA?

What did GSpot say about your problem-mp3? You don’t have a normal version of the same song? Even .wma would be fine.
