Fields, fields…
I’ve recently completed a 30 sec spot for an ethnic cable channel.
I’ve shot HDV 1080i50, converted it to DVCPRO 1080i50, scaled and repositioned it in a SD PAL Sequence. Final Delivery was in AVID Meridien Compressed 3:1.
Now, as far as i know and see, all these formats are upper field first. I made sure the sequence was upper too. Now the cable station is saying the fields are flipped, or something of that order (communication with them is limited).
I checked and I don’t see any problems. However I don’t have a PAL monitor, so I may not see everything. Can something happen during scaling and positioning? I remember removing a few Shift Field filters because I felt they were making the image soft, but now I’ll never remember where and why I did that.
Does anyone have any advice? If you’d like, you can see the file I sent to the cable station here:

i also suspect they may be needlessly busting my chops.I’ll appreciate any advice. I would prefer not to go back all the way to recompressing the original HDV footage.

My guess is that you didn’t flip the fields, but rather they need lower (even) fields first. SD PAL is lower field first.

not the case…
AVID Meridien Compressed Codec with settings:
Video Format: PAL (720×576/25fps)
Color Input: RGB
Resolutions: 3:1 Interlaced
Upper field first -
[alichek] “not the case…”
Uncompressed PAL, yes.
DV PAL, no, that’s lower field first.

What happens if you simply deliver as an Animation Codec project and let them re-render in their Avid?
I never had luck exporting with any Avid codec on our systems so if I have to send to an Avid system, I simply use the Animation Codec. It’s worked brilliantly here for 4 years now.

well, i posted their specs, which are what you’ve seen. i wish i could send them animation codec, but i don’t have a direct contact with them, only through the advertising agency that subcontracts me.
in any case, i’m sticking with upper first throughout. any ideas? i can take it through my avid xpress pro, but that will only add two recompressions to the footage and doesn’t avid use quicktime compression on export anyway?

Most of the shots are correctly Upper Field but two are Lower:
