Kona downconvert monitoring, field order issues.
Successfully captured Z1U 50i pal hdv via hd analog outs and Aja HD10a converter to a 1080/50i dvcproHD PAL sequence in FCP5.
Final project is for NTSC but experimenting with 50i/25 for the frame rate.
1080i/50 hd PAL plays back fine on our sony L series monitor which is auto ntsc/pal. Coming from k-box component analog outs. FCP Easy setup 1080i/50 dvcproHD.
Then switch the Kona to down convert to 625i for monitoring, playback is fine.
Use Nattress Standards Converter to convert originally captured hd pal clip to hd ntsc…works great… 1080i/60 ntsc hd plays back fine on monitor.
Then switch the Kona to down convert to 525i…this is where the sony monitor freaks…footage is very jumpy, like a field order issue.
HDV 1080 pal or ntsc is upper field right? Which I am not capturing but just curious.
DVCPro100 HD PAL is also upper field?
DVCPro 100 HD NTSC is what???Thanks so much!

This was taken from the Algolith website knowledge base:
For NTSC footage the field dominance is “Lower or Odd Field First “, for all HD formats and PAL, the field dominance is “Upper or Even Field First “.

Algolith makes software based standards/format conversion products.
The exception to the above statement is the old ABVB Avids — the ones that were AVR77 versus the Meridien 1:1 — which were Upper Field dominant, but no one has those much anymore.
Check out this link and goto the HD/ECinema link. Many good documents on workflow and tech.
