Hi All,

I've been given broadcast specs for a spot that needs to be delivered to Italy and am having some issues.

Source Video:
ProRes 422 (HQ), 1920x1080 Progressive 23.976 fps
Requested Specs:
720x576 16:9 FHA
ProRes422, Progressive
25 FPS
How do I create the 720x576 16:9 FHA aspect ratio? 720x576 seems to be a 4:3 aspect ratio.I changed the aspect in export to D1/DV PAL Widescreen 16:9 with ProRess 422 (HQ). Two thin, vertical black bars appear on either side of the video. Is this correct?

The other issue I'm having is I'm getting a report back that the spot has aliasing/double frames. Am I creating this aliasing in how I export?

My current export settings:
Apple ProRes 422(HQ)
720x576
25 fps
Upper Field First
D1/DV PAL Widescreen 16:9 (aliasing report was from a square pixel export)
Maximum Render Quality
Any assistance would be greatly appreciated.

P.S.
Does my sequence settings have any effect on the export?
Sequence Settings:
ARRI Cinema
1920x1080
Square Pixels
Progressive (Upper Field First was the sequence settings for the previous export when I received the complaint of Aliasing)
25 fps

Thanks!

[Randy Rubin] "Two thin, vertical black bars appear on either side of the video. Is this correct?"

Square pixels and non-square pixels are a bit different so that happens. You can choose the scale to fill option to crop your image a bit and fill the image up.

[Randy Rubin] "double frames"

You are going from 23.976 to 25 so Premiere needs to add a frame to every second to keep the duration same. If the length of your video isn't fixed you could bring in the master and change the frame rate with the interpret footage settings. The lenght of the clip would be a bit shorter (because the clip would be running in 25 instead of 23.976) but it would show every frame without doubles.

Thanks I wrote that wrong. The source is 25fps.

What about aliasing? Is there anything I can do about this? I'm kind of stuck here.

Also, how do I go about the scaling option. Thanks so much!
