interlaced footage

Posted by John Desay on October 16, 2009 at 1:27 am

Hi Guys,
Just a quick question for ya…

I am cutting a short at the moment that was shot on a Sony HVR-Z1.It was shot at 108050i and since it is probably going to be marketed on DVD,what i wanted to know is-is it better to put a de interlace filter on the whole project to get rid of the scan lines for TV or is it better to downconvert the project to a different format.Also just wondering that if it IS best to put the filter on,does it degrade the quality of the picture and if so is there any way around this…

Thanks for yer help guys,keep up the immaculate work!

Cheers,

john.

Don’t need to de-interlace unless you want your short to look progressive.

Thanks for the reply Rafael.

I dont necessarily want the short to look progressive but when i export the movie as a quicktime and then burn to disc using Toast,it always shows the scan lines on my TV so this is what i want to get rid of-i thought once your footage was going to be shown on TV it had to be de interlaced first?

Thanks again

Hi John,
In a normal interlaced TV (CRT) you shouldn’t have any problem with interlacing lines.
If your TV is one of these and you are seeing interlacing artifacts it may be a problem somewhere managing the field order.
To see the scan lines (of interlaced stuff) is normal in progressive monitors.
De-interlacing is the only way to get rid of them.

Thanks again for the reply Rafael.

I’ll just run thru my whole export to see if you can figure out where my problem lies…

My short was recorded at 1080i.My sequence settings in FCP for my project are…
Pixel Aspect Ratio HD(1440×1080)
Field Dominance Upper(Odd)
Editing Timebase 25
Compressor HDV 1080i

I then export the sequence as a QuickTime file using Current Settings so as not to change anything.
I then burn the QuickTime file to DVD using Toast.
When i watch on my TV(Sony Bravia LCD) i still see scan lines on most of the shots.
Am i correct in saying that because my project is interlaced(1080i)and my TV is also interlaced i shouldn’t see any scan lines?

Thanks again,

john.
