mpeg2. i think what’s going on is a discrepancy between apple/quicktime reading of the mpegs size and the way adobe and media encoder are creating it/reading it. i found an cow afx thread on this where the conclusion seemed to be:
“If your footage is 16:9 then you should encode it as a 16:9 MPEG-2. In QuickTime player this 16:9 MPEG-2 will have an odd frame size (720×404) but that is normal and correct. ”

as a test i did the same routine with apple compressor and the resulting mpeg widescreen file reads as 720×404 in quicktime pro but interprets as 720×480 (1.2) in premier and burns correctly to a 16×9 NTSC widescreen DVD in encore. go figure.

if i uncheck the 16:9 button then the rendered mpeg is 640×480 and the video is letterboxed black top+bottom.
something i discovered is that the media encoder rendered mpeg, which qtime pro infos/displays as 720×404, when imported into premier, premier interprets & displays it as 720×480 (1.2). i went ahead and used those mpeg files to send to encore where it seems to produce a correct widescreen DVD without re-encoding. so the problem (or non-problem) is solved but the question remains for now, i guess. i wonder if it’s just a different quicktime player interpretation than adobe is using on wide-screen mpegs that media encoder produces. the 720×404 size is a square pixel 16×9 aspect ratio.
have you ever created this format mpeg2 files? what actual dimension are they in your experience in qtime? anyway, thanks again for your time.

the source movies are animation codec quicktime rendered from afx in NTSC DV 29.97 widescreen format, no audio. in premier (and qtime pro) they are info’d and display correctly as 720×480 (1.2) 29.97. they are on a NTSC DV widescreen timeline that is the same.
the media encoder settings are;
FORMAT MPEG-2DVD, settings 720×480, 29.97 dropframe(fps), progressive, quality5.0,,
VR, 2 pass, min 1.50, target 6.36, max 7.99, there is no audio, the widescreen 16:9 radio button in settings is checked.after the encode which produces a 720×404 mpeg2, this is the info from the xmp file that encoder creates:
it seems straightforward but isn’t somehow. can you confirm that the mpeg2 file that should be created would 720×480 and that 720×404 is not a size that is somehow stretched vertically back to 480 when you burn the DVD in encore? thanks for taking the time to look at this. it’s driving me crazier.

well this is odd to me. i threw away the premier preferences, re-imported the NTSC DVwide movies into premier wide project, then export to media encoder. the video now fills the media encoder output window correctly but with the widescreen mpeg2-dvd settings the resulting exported mpeg2 file is still 720×404. (i’m finding the rendered size by opening the rendered mpeg2 file in qtime pro.)
-
thanks tim for quick back. no, it’s a 16×9 aspect ratio (unsquished in H) in the media encoder output window with black on the sides and the top. do you know what’s up with the 720×404 output from the encoder?

Hey John, I’ve been trying to do this but am having trouble. Your directions and the manual indicate “After choosing the Project function, a dialog opens. Use this dialog to choose the type of projection”, but when I do that no dialog opens, nothing happens, nothing in the attributes manager. The option is there and available, I’m using a plane and an editable open bezier spline in front. I’m using C4D R10. I’m obviously missing something, any idea what?

just wondering, why would you want to, or have to change 30p to 24p. i hope it’s not something goofy like “it looks more like film”.

“Don’t use the H.264 codec inside QT – strange things happen.”
Huh? That’s seems to be a odd bit of unexplained general advice. Is that meant for PC users? On the mac we use quicktime h264 in a wide variety of shapes, sizes and frame rates every day with no problem. Couldn’t actually get by without it. Did you mean as an editing format? Care to elaborate.

if you want to save some time and money, maybe check out the $20 photopresenter software from boinx. if you want to spend some time and figure the effect out in afx, check out nulls and 3D cameras as suggested.

hey rick, your technique works pretty darn well, ends up being a slightly thick dark line that looks good at small repro sizes but is bit chunky/rough viewed at actual size. i think i prefer the result i get just using the “stylize/find edges” filter and then removing color and adjusting levels from there, doing a bit of hand work as needed. might not be better for your jobs but as with most pshop things there are always several ways to do anything. thanks for sharing your approach. if you have it, maybe take a look at illustrator trace sometime for a vector approach to this look.
