Need HELP - 24p filming and editing

I have to shoot new footage for work and I would like to do it in 24p so I was out today doing some test filming. I'm using a DVX100b and I shot everything in 24p mode... captured it using Adobe Premier Pro and burned the footage to a DVD to test the quality. When buring the DVD I changed the setting to be Progressive or "field = none". The footage seems horrible and there's TONS of lines everywhere like every other frame... here is a picture from the progressive footage.... http://i7.photobucket.com/albums/y297/IntuitiveDesign/24plines.jpg

I thought only interlace footage has lines like that? Isn;t that the point of progressive video... to make it look smoother and sharper? Am I doing something wrong when filming... capturing... buring??? Can someone please shed some light on what is going on?
 
Yes, that's interlacing. My guess would be in your capture process... but I don't have any advice to give. I don't work on Adobe.

Also, what mode are you shooting in? 24PN, or 24PA?
 
I found an article that states the following but I'm not sure if this is what is happening....

"Telecining is a method by which progressive video that runs at 24 fps (such as a film) is converted to run at 30 fps (or 25 fps for PAL/SECAM video).
For NTSC telecining, also known as 3:2 pulldown, interlacing artifacts are caused by duplicate fields of video that are used to increase the number of frames displayed each second. It is possible to remove these interlacing artifacts and restore the video to its original 24 fps with little or no quality loss. The process can be a bit confusing, so I've written another article that deals specifically with Telecining."
 
theres another post with this but you must have skipped it

"depending on the version of final cut it will automatically remove the 2:3 pulldown from 24p normal footage just capturing with
easy setup DV / NTSC
if you then reverse telecine (with cinema tools) your footage you are making it 24p for a 23.98 timeline and should be progressive without the interlacing lines
24p captured with 2:3 pulldown is actually 60i footage and will have interlacing lines on the footage
this is why you can edit 24p, 30p and 60i all on the same timeline
de-interlace if you want your export to not have any interlacing
or reverse telecine and create a 23.98 timeline

read this for a very good explanation of 24p http://www.adamwilt.com/24p/

i think i got all that right, im kinda new and have been learning for a little while now, but if im wrong about anything im sure someone here will correct me
hope i helped i little bit"

of course this is for final cut and i believe adobe works the same with the whole 2:3 pull down on the capture atomatically
but if you want your footage to be progressive either reverse telecine with adobe (if it can) or use another program for it, or deinterlace your footage with a plug in, or program
 
Yep, I actually just found that post. I guess the issue might be that Premier Pro 1.0 doesn;t support REAL progressive scan video capture. Does anyone know if upgrading up to Premier Pro CS3 solved this issue?
 
Premiere Pro 2.0 and later handle the pulldown issue automatically and seamlessly on a 24p timeline. Premiere Pro 1.0 and 1.5 had notable issues with standard 24p pulldown.

But you also have to export as 23.976 and progressive -- just using an NTSC template won't do it. You'll reintroduce pulldown and interlacing if you use NTSC.
 
I had a similar issue with premiere pro CS3 and this is caused by not checking the "deinterlace" box when out putting to DVD

de-interlace if you want your export to not have any interlacing

No. Do. Not. Deinterlace.

If you're exporting for DVD, export as MPEG-2, 23.976, progressive.
 
Doesn't 24p Normal have interlaced frames built into it already? So you will see some interlaced frames and some progressive.

For the truely 24p experience, shoot in 24P Advanced.

Right?
 
24pA also has interlaced frames "built into it." The only difference between the two is how they're arranged.

And technically, until you remove pulldown, all of the frames are interlaced, whether standard 24p or 24pA.
 
He says he's using PP 1.5, in which case, with 24p standard, he's pretty much out of luck -- even when the standard pulldown removal is working, it will still often produce bands in the footage. This was a well-known problem.

Which is why I wouldn't recommend anything prior to 2.0 for 24p work. After that, you're golden.
