1080 p footage workflow CS4
I am trying to get a workflow for some 1080 50p footage from a Panasonic SD 700.
I use cs 4 premier and AE cs 4
I Edit in Premier with the sequence at 25 fms progressive as there is no option for 50 progressive.
I want to know this. I want to output to format that keeps the 1080 1920 and is 25fms per second. With every very combination that I try the final render is of a very degraded quality. I have tried using intermediate raw footage and also rendering directly from the premier sequence at 25 fms progressive. I also bought footage directly into AE and made a composition with this footage then tried a variety of render options.
Ideally I would like to output to a pal format from a quick time conversion. I need to submits for a competition and they prefer "quicktime Pal data dvd" Is there something that I am doing wrong? I am not an absolute novice and so am a bit at a loss.
To recap 1080 1920 25fms progressive through AE then final output to what format to maintain quality?
If not using 50p as in cs5 or other software is there shooting in that format in the first place othere than having that footage for a later date/edit?
Thanks in advance
Use Adobe Media Encoder to render out your project. You can open a AE project in AME and render to MPEG2 for 1920x1080p 25 fps. This should give you a good quality output.

I just looked up the specs on that camera you used. It may be able to shoot 1080p, but it will NEVER, EVER be able to shoot 1080p 50. It can ONLY shoot 1080p 25... and it can't even record complete 1920x1080 frames.
It uses a recording scheme called Progressive Segmented Frame (PSF), which is a LOT like interlaced video. For all practical purposes, it IS interlaced video. I'd also guess that the actual resolution is 1440x1080 and not 1920x1080.
So what you need to do is this: In AE, go to the interpret footage settings and interpret this as upper field first. Then render (don't export!) with the Render settings on Best. Your video may get better-looking, but I make no guarantees. That's because you shot on HDV and you run AE 9, not AE 10... so the following advice still applies:
Dave's Stock Answer #1:
If the footage you imported into AE is any kind of the following -- footage in an HDV acquisition codec, MPEG1, MPEG2, AVCHD, mp4, mts, m2t, H.261 or H.264 -- you need to convert it to a different codec.
These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.
In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems.
I'm a Mac guy, so I like to convert to Quicktime movies in the Animation or PNG codecs; both are lossless. I'll use Apple's Compressor, Adobe Media Encoder or Quicktime Pro to do it.
