Primary School end of term achievements and play.
During capture using Power Director 7 the picture is perfectly ok.
After Capture in Edit when the video is played along the timeline,
if the camera is panning or somebody moves, all the vertical edges of
anything in the picture distort badly to resemble alternate teeth of a saw.
I am now playing the video on the TV direct from the camcorder with
no sign of the slightest distortion.
What is PD7 doing to the captured video to turn it into such a mess
and completely unsatisfactory for burning to DVD?
We’ve had this Canon MV850i (interlaced I think)
camera since July 2005 and only just now in the last couple of months
experienced this distortion problem using PD7.
Pinnacle Studio 9 came free with the camera and we used that for
about 4 yrs till we purchased PD7 in June, 2009 and did not experience
the problem till 2010.
If interlacing is the problem then it has only just happened in the
last few months which seems illogical to me.
The only thing I can think of that may have affected things is that
a setting may have been accidentally changed on the camera such as SP
Would that make it happen?.
Or is something else at fault?

Hi Phil, I had this the other day – luckily with a test shoot to try out a new stereo video mic and it turned out I had inadvertently switched from PAL to NTSC or whatever and when I ticked the PAL box it disappeared. Don’t know if it will help but that’s what happened so I thought I would offer it. If it’s not that particular setting, you can bet your life it’s another setting that’s up the creek.

Your cam shoots interlaced video. When viewing interlaced video (i) on a computer monitor (which is progressive scan = p) you’ll end up seeing the interlaced scan fields when there is extreme movement in the shot. Depending on your software, you may be able to select ‘Deinterlace’ which will cut down on the ‘saw-tooth’ as you called it, but will also cut down on your image resolution. If you’re outputting to the web you may elect to deinterlace the video to smooth it out some. If you’re burning to tape or DVD, leave it alone it will be fine. BTW, if your video is intended for viewing on TV’s in the US, Canada or Japan that’s NTSC standard so don’t ‘flip the PAL switch’. PAL is the European standard and though you’d be able to watch it on a computer monitor, you won’t on an NTSC standard TV.
