my video always interlaced

[humbleboy]

Hello all
I noticed that some of the DVDs I create are interlaced especially on high motion it blurs and screen is not clear at all but I am not able to determine at which stage exactly this is happening.

I use powerdirector 3 to transfer video from Sony mindiv as dv avi , edit and export as mpeg2 720x480 8000 bitrate then I author in tmgencdvdauthor and burn in Nero 6

Edit: sometimes i use dvd shrink to fit but not more than %80

What can be wrong?
Thanks for any help

Hi humbleboy,

If you're viewing your DVDs on the PC monitor, seeing interface effects is normal as a PC monitor is a progressive display. Play the DVD with something like WinDVD or PowerDVD.

Better still, test the DVD out by playing it on a DVD player linked to your TV, if you're not doing so already.

If you still see the effects on the TV, you might be encoding with the field order the wrong way around. DV AVI is usually lower field first - if that's how you've been encoding it, then try upper field first.

Hope that helps. Good luck...

It still interlaces when playing in powerdvd or windvd and the same when playing in stand alone dvd.
The problem now is that powerdirector has not got an option to change render values (upper and lower field) so I will need instead encoding software from dv AVI to mpeg2. Any suggestions?
Thank you

Hi humbleboy,

I don't know PowerDirector, so I can't really help with that.

I believe that the field order is dictated by the cam and is then recorded during the process of creating the DV footage on the tape. But the fact that your problem isn't consistent is curious...

Your process sounds normal, so I can't see why you'd be getting this problem - especially intermittently.

Post a screen shot of a typical problem frame. It'll help people see what you're problem is and may give rise to a possible solution.

i will post screen shot when I go back home.
now i have another problem, i exported my work into DV AVI type 2 (traditional) as it says, instead of mpeg2 to see if there will be any difference but now there is about %30 loss of video quality. I wonder why is that happening ? why quality degraded that much ?

Try using WinDV to capture to DV AVI from your cam. See if that makes any difference.

If your "capturing" DV from the cam there should be zero quality loss, it's a lossless transfer. It's no more complicated than copying a file on your HD from one folder to another except that the HD has to write the data fast enough.

As far as interlacing check out this thread, https://www.videohelp.com/forum/viewtopic.php?t=257631

If it's footage from a DV cam then use lower field first and maintain that throughtout your process.
