File conversion for DVD

Jan 1, 2013 7:10 PM

I shot some material from an event and I am having an issue with encoding to a DVD. It was shot at 1080i and I first made a WMV movie that looks absolutely perfect. I was asked to run it to DVD and a problem occured. Everytime their is camera movement the picture stutters. It almost looks like some type of interlace flicker. When the shot is locked in it looks fine. As soon as the camera pans the flicker starts; it's almost looks like a blur affect.

 

The original plays fine on the timeline. The WMV file looks fine at 720p. I used the encoder right in Premiere to export for DVD. This is not anything important but I still want it right. This is the first time I encoded something from HD that has movement in it. It is best to lay it on a 720 x 480 timeline and then render out?

 

Any suggestions. I not sure what happening to get the flicker.

 

Thanks.

    What were your encoder settings?

     

    A screen grab would help us.

    The video should look fine with those settings.

     

    What camera was used to shoot the footage?

    OK.

     

    Next, what settings were used on the camera?

    I'm just not seeing anything wrong with what you're doing here.  Your work flow should produce excellent results, and does for my own similar footage.

     

    Any chance you can upload an exported file we can see?

    Fast camera movements actually do flicker. It's the nature of the beast -- motion pictures are actually just a rapic succession of still picture frames. If the difference between the individual frames is too great, we see it as flicker. It's acutally pretty amazing (to me anyway) how slowly I have to move the camera to get smooth motion in the final product.

    At 24p that's to be expected.  But shooting at 30i, it's a very different story.

    It's my understanding that DVD video is lower field first. You might try changing your feild setting from auto to lower.

    The dvd itself might be lower, but the mpeg file should be upper, like the source.

    I once thougth that. My understanding now is that the files on the DVD can be either. As Ann says, the important part is the source and transcoded file matching.

    I never use auto settings.

    I always set everything manually, just in case.

    Your max bitrate is almost the same as the target bitrate.

    How long is your timeline?
