NTSC DV footage into a NTSC DV WIDESCREEN comp…
hey everyone…
i’m having a little trouble here.
i’m on AE CS3.
from what i understand…when you hit TOGGLE ASPECT RATIO CORRECTION,
it shows you what it’d look like on an actual TV screen right?ok…so…we’re doing a demo reel for our company and needs to be in NTSC DV Widescreen, but…i have a lot of footage that was just recorded in regular DV (0.9).
so my question is…what as i suppose to do with those 0.9 files?
do i interpret them to 1.2??
or do i just leave them alone and bring them into the comp just like that?because…i was fooling around with it, and when i DIDN’T interpret the footage, it looked squeezed, but when i toggled the pixel aspect ratio correction, it looked perfect.
BUT
when i DID interpret the 0.9 footage to 1.2, it looked REALLY stretched when i toggled the ratio correction.
so….what IS exactly the right way to use 0.9 footage in a Widescreen project?
thanx a bunch,
_chris

,9 footage is 4:3. “fullscreen”.
1.2 footage is 16:9. “widescreen”.Interpret the footage as it is: .9 or 1.2.
Drag it into the widescreen comp. It will be cut off top and bottom.
Or you drag it in, then fit to height (cmd-opt-shift-G) so you have two black bars on the sides.4:3 footage will not fill the screen and look correct. You have to cut it off or “pillarbox” it, with black bars on the sides.

wait wait…i got kind of confused when u said “Interpret the footage as it is: .9 or 1.2”
so if i have a clip that i KNOW is 0.9,
do i conform it to 1.2 before i drop it into the Widescreen comp or do i NOT? -
no, as long as ae is correctly interpreting the footage as what it actually is, when you take it into a comp with a different px aspect ratio ae will correctly compensate for the mismatch…
if you need the 4:3 footage to fill the 16:9 comp, you will need to scale it up to fit it to the new size. ae has a function in layer>transform>fit comp width that will do it automatically. you want to scale the footage proportionally, not stretch it to fill the wider comp.

No.
If it IS .9, make sure it is INTERPRETED as .9. Do not re-interpret or conform to 1.2.

does that include FRAME RATE as well??
i mean…if the frame rate of my comp is 23.976, and the footage i’m dropping in is originally 29.97,
do i interpret the footage to 23.976 before i drop it into the comp or do i just leave it as is and drop it into the comp?please let me know
thanx,

if you want the footage to keep the same timing and duration, then leave the frame rate alone (if it is correctly interpreted)… ae will correctly adjust for the mismatch in frame rates.
for example, if you drop 29.97 footage into a 23.976 comp, ae will drop frames (every 5th frame) to maintain the timing… likewise, fi you drop 23.976 footage into a 29.97 comp, ae will add frames to maintain timing (how ae adds frames can be set with frame blending options, also plugins like timewarp can be useful if adding frames, checkout videocopilot.net for a tutorial on one method of frame rate conversion).
if you wanted to change the timing of the footage, you could use the interpret footage settings to tell ae that the footage is a different frame rate… for example, if set ae to interpret a piece of 29.97 footage as 23.976, the result would be a slow-motion effect… note, you could also drop the 29.97 footage into a 23.976 comp and apply layer>time>time stretch and set it to 120% and achieve the same result.
either way, if you are changing the frame rate of interlaced footage, make sure ae is correctly separating fields, and you may want to enable the preserve edges option.
