Joe,
Now this makes sense. Never thought about it though. You
could definetly get more onto the DVD. Hmmmm… Interesting.
Always more for me to learn. Thanks very much for digging
up this answer.

By the way, you work for Adobe right? Well, as I’ve said,
in the surveys they’ve sent me Encore is a great tool. Even
though I’m still learning, I can get it to do everything
I want to. 🙂

Thanks again for the help.

Joe,
I appreciate your responses, but I must be failing to ask the question
correctly. I understand that DVDs are 29.97FPS MPEG and that a 24FPS MPEG
must be upsampled through the use of the pulldown method. However, my question
is why would anyone create a 24FPS MPEG in the first place? Why not just
create the MPEG at 29.97 when it is originally created?

Thanks

Mark

Joe,
Why would someone create a 24FPS MPEG if it is going to
be converted to 29.97 via DVD player? Why not just create
the 29.97 MPEG instead?

Thanks for the help.

Aw.. That makes sense. Thanks for the explaination, but
why would someone do this? Not to be too pesky, but
why would you create a 24FPS MPEG-2 and then leave the
conversion to the DVD player? Does this give better
results or more film like effects?

Thanks

Another thing to try is to set you camera up to
take a frame or two every minute. This way the
whole thing can fit on one tape. I know my little
sony can be setup to do this time lapse videoing.

You might want to change the quality value
of the encoder. I’ve found that a Q=3.0
gives good results and take about 1/2 the
time that a Q=4.0 would take.

Just for comparisons: I just did a 20minute
DVD with motion menus and it completed in
about 1 hour and 20 minutes. However, my
Q value was 5.0.

Just more info…

What does the 24p flag do on the DVD? I thought
all DVDs were played as 29.97 for NTSC?

Is this the ubercool thing that makes my NTSC
video more film like?

Thanks

My understanding is that you should only have to
use the reduce flicker if you are outputing to
interlaced video. The reduce flicker effect actually
blurs the text so that crossing the different fields
during the roll doesn’t make the text flicker.

If your output is progressive video you probably
do not need the reduce_flicker option.

If you are outputting to interlaced video, the biggest
factor is the speed of the text. Moving at the wrong
speed can cause only one field of data to be drawn,
thus reducing the resolution of the text by half.
If you have it the Meyer book has a good section on
this.

The biggest issue with title rolls is interlaced video.
The text must move up or down the screen with the correct
velocity (pixels/frame or pixels/field). If an incorrect
speed is used, then flickering or pulsating of the text
happens on interlaced TVs. Unfortunately, you won’t see
this on the computer screen.

The second motion graphics book by Trish Meyer(sp) has a
very good section on this. I haven’t looked at it in a while,
but if I remember correctly the speed must be an even multiple
of the field rate. 2*60, 4*60… etc.. The unfortunate thing
is even the slowest value is really fast on the screen.

My solution has been to use 1*60 but then apply a vertical
blur of 1 or 2 pixels depending on the font used for
the text.

Hope this helps.

Brent,
I don’t know much about this, but I was watching the
Total Training for the PPro2.0 and in it, Jacob mentions that
there is a specific type of RS422 cable you need to use
with PPro2.0. If this cable isn’t used, then machine
control will not work. Hope this helps and wish I knew
what manufacturer made the cable.
