New project rendered an eyesore...

I just burned a project to DVD over the weekend and what an eyesore. Almost every movement has that paused blurr effect that give you a fricken headache. I think I may have had the shutter speed set differently on my camera when shooting. Burned a few other projects where i used this camera and it was crisp, clean and clear so it had to be a setting on the camera.

My question is can i correct this in Vegas or at least attempt to?

Normally, I would've said that it's a field-order problem but if you say that previous projects came out ok then ... well, I'm not really sure. Are you sure you haven't changed the field-order?

Hi Tim,

Well, basically, a TV doesn't display frames like a PC monitor but something called fields. A frame is divided into two fields where a field has half the number of vertical lines of the frame. In the case of PAL, there are 50 fields per second giving 25 frames per second. A TV will display the first field for 1/50 second by displaying the lines of the field at every even numbered line of the frame. It will then, during the next 1/50s, display the second field at every odd numbered line of the frame. This means that a frame is not a snapshot of a single point in time but a combination of a snapshot of time t seconds and time ( t + 1/50th ) seconds. Consequently, the order of displaying these fields is important for the playback to look smooth. Get these fields round the wrong way when rendering any you'll have a strange jerky look on anything that's moving.

When you render your DVD there is a setting on the video tab where you specify which field comes first ( they're described differently by different programs just to make things worse! ) I think Vegas uses the terms Upper and Lower field.

So, if your DVD looks jerky and it's rendered with Lower field first, try rendering it out again with Upper field first and see if that looks any better.

Hope this helps,

Scott
