View Full Version : Top gun

Did anyone notice a problem with the frame rate cadence on Top Gun -
especially on HDTV. It seems that they tried to covert from exactly
24FPS to 50 fields per second - frame blurring, jumping - ugly.
It's like they didn't have a "PAL" (well 25fps) version to play.

What kind of display were you watching at the time? I noted the same thing
from my projector. Very annoying

It was actually via the HDTV card in my PC. I recored a bit and frame by
framed it - not good. Also if you looked at it full speed on a panning
shot, you got a shimmering effect with a period of about a second -
which would also fit in with my theory that they just squashed 25fps on
top of 25fps - every 24th frame you have to double up, or blur the
frames around every 24th frame so it wasn't so obvious.
I wonder if this is going to be normal for HDTV material - i.e. we get
24fps material from the US and they do no "PAL" (I know, HDTV isn't PAL)
conversion on it.

They should've sped the 24fps to 25fps themselves then ;).

Yes, I noticed it too. I think they grabbed a field from every 24th
frame and a field from every 25th frame to create a new frame they could
insert after every 24th frame to create 25fps. It's cheap and nasty,
considering the technology exists to perform true motion interpolation
between 2 frames. It makes more sense for them to interpolate frames
than speed up the video and then have audio pitch issues to worry about,
but I wish they would use a better interpolation method.
I ditched my HD capture because of this and PQ being a bit blurry and noisy.
Audio also seemed to be only DD2.0, or did my processing mess up the flags?
