SD client review file from HD
Hi
I’m more AE than PremPro so apologies if this is dumb.
I have a 1440x1080i25 (pr 1.33 anammorphic) project and all I want to do is show the client a half-size square pixel approval mov. I can’t seem to find the correct settings; either I get black borders top and bottom (720×540 pr 1.0) or an anamorphic frame. I would really appreciate any help on this; I would like to keep 16:9 but just half-size. This is for PAL.
Thanks
A

Try 864×540 Par 1.0 or 720×540 Par 1.2

Sorry, should have said 960×540 Par 1.0 or 720×540 Par 1.33

C’mon Harm you use PAL, where are you getting 720x540?
That’s not a recognized frame size format, it won’t be imported into a DVD Authoring App.
720×576 (1.422 – PAL Widescreen) PAR. or 1024×576 Sq Pixel

I know John, but the OP only mentioned the resolution he tried. He did not mention delivery on DVD, it could be web based, FLV, WMV or whatever. I took the Vimeo HD standard, 1280×720 1.0 for 16×9 and translated that to the vertical resolution of 540 he wanted. Hence the 960×540 1.0.

Jon,
In addition, if the OP wanted a DVD in PAL format, what would be easier than just selecting one of the PAL presets in AME? I assume he had a specific reason to use 540 vertical, possibly to send a WMV file with YouSendIt.

Harm, with all due respect. This bloke obviously isn’t savvy to screen resolutions and has assumed that 50% of his HD Frame would be SD. 540 with a 1.33 PAR is bogus. It’s not a proper aspect ratio, he may aswell use 50% in Sq Pxl PAR (860×540). 720×540 is just confusing. This guy probably would do best to use the AME PAL Widescreen Preset – and he probably didn’t know of it.
I’m not having a go at you, but telling someone to use an anamorphic widescreen SD res in width and not correct them with the standard format for downconverting for client preview for DVD (which I know all clients want to play on DVD or Computer) sends a confused message. There are too many fresh from film school filmmakers that don’t know about standard settings. 540 is not a “standard” anywhere. The 1.33 PAR is for HDV not DV res in a standard workflow.
I just want to avoid the next post about why his 540 line file won’t work in Encore to make his final DVD.

Hi guys
Thanks for all the interesting discussion, although I never meant to absorb so much of everyone’s time, I was just looking for a quick bit of advice. I didn’t need to make a DVD, only a smallish file that the client would view online and then comment on. I normally work in AFX and outputting files in various sizes and formats seems to me a little easier, I rarely use PP and so was in unfamiliar territory and needed help. So, thanks. Although I am still not entirely clear… say I want a size that’s, say, a quarter height of the original format (1440×1080 ana) how do I work out the width and in what PAR?
Thanks again.

1440×1080 is anamorphic FullHD, which therefore isn’t real FullHD. It fakes the resolution of FullHD (1920×1080) by stretching the width (1440) by 1.33 PAR making it appear to be 1920. Anything you view online should be set to square pixel aspect ratio as some playback apps might not respond properly to the stretching fake widescreen of anamorphic video.
1920 / 16 = 120
120 x 9 = 1080this is 16×9 square pixel.
take this shape and divide the figures by the % you want to shrink it by. Keep to a size for MB size. I use 512×288 as the bare minimum for client approval for HD stuff.
25% of fullHD 1920/4 = 480
25% of fullHD 1080/4 = 270480×270
Hope this helps.
