Serrated SD Donconversion
on May 24, 2007 at 7:22:18 pm

I am having trouble down converting HD to SD Component (Beta) through a Kona LH.

Down conversion looks coarsely serrated on objects moving cross screen and diagonals are jaggy when playing but smooth out when paused.

It's just the opposite of watching normal interlaced SD that shows the interlaced fields when paused, smooth when playing.

Sources have been HDV 720p30 captured from firewire as HDV and AIC, captured from component as uncompressed Kona 720p59.94, DVCPro HD 720p60 and DVCPro HD 720p30.

SDI Out 1 set to whichever format the test clip was captured.

SDI Out 2 set to 525i29.97/crop to Ensemble Serial Box 1 to Sony PVM1344Q component monitor.

Analog Out set to Secondary 525i29.97/Component (Beta) to PVM1344Q.

All results are identical.

What am I doing wrong

Oops. Scrambled the title pretty good on the first try.

I have the same problem: footage 1080i50 downconverted to 625i25.
The footage from Panasonic HVX200 looks OK when downconverted by the camera itself.

There were several responses to my second post, a little higher on the page. "More serrated SD downconvert".

Haven't found a solution to my problem yet, but there may be something in those responses that will help you.
