Got a video question?

Question

1

I have made a wmv from a dv resolution 1 gig quicktime (project shot in DV) in flip4mac. There is one spot in the tape where there are jagged edges. It appears in a wide shot. A man in a white shirt is walking from right to left. He's pretty small in the screen. But I can't get his shirt to stop being jaggedy as his body moves.

I've tried cbr one pass, cbr 2 pass, vbr one pass and 2 pass, and constrained.

The jaggedy edge is not in the quicktime, however, when I make a lower resolution quicktime in h264 from this dv quicktime, I get the jaggedy edge too.

Any ideas on how to help?

Be sure your conversion has the correct field order -- dv is lower first -- if you are working with interlaced video, or de-interlace. If you get the field order backward, it causes jaggies. Another reasons for jaggies can be resampling, particularly at a different frame rate from the original. HTH / B.Vaughan

some file conversion programs allow you to 'deinterlace', you should do that if you have the option. sometimes different file sizes will show interlacing (i see it on .movs that are 640x480) and some will not (if i go smaller to 480x360, i see no interlacing). it's weird!

did you cut/edit it on your own, or did you just convert it ?

If you just converted, it could be it is already in the original file, but you don't see it, because the decoder/player copes with it very well.

if you edited it, was this 6 second footage of another camera or input format ? you might need to apply a deinterlace-filter on that sequence.
