Im working on a project right now. I shot some stuff at 30f standard def, imported it into a 24p timeline, interpreted the footage as 24p and got some wonderful slow motion.

Everything looks good in the player. I export the file, i open it within adobe premier pro cs3, things look great.

Now, i open it in windows media player, media player classic, etc.. Every 5th frame is interlaced!

I have seen this before with pulldown issues, but this is rediculous, normally its every 4th and 5th frame, which gives it away, but now its just every 5th frame and i don't have a clue how to fix this.

I need help as quickly as it can come please guys.

thanks

okay, i just burned a DVD and this 5th frame interlacing does not seem to be there on a television screen, so i guess the question is, why do i see it in the first place?
 
no, don't need to de interlace the footage.

I am just curious to know what is going on

I am exporting it using the generic 24p settings in CS3. Microsoft DV AVI, 24p, progressive.

Normally footage is fine. If i were to import 24p footage and export it as 24p, no problem.

I imported 30f footage, interpreted it as 24p, imported it into the timeline. Footage rendered, looked great.

Exported it, opened it in windows media player, every Fifth frame was interlaced (pull-down issues in the past were normally skewing the 4th and 5th frames not just the fifth )

Tried it in media player classic, same issue, every 5th frame is interlaced. Now this must be a pulldown issue, but why is this happening? If i export the file and then open it in my source monitor in CS3, no issues, its only when i open it out of the program.

I tried then to burn a DVD, this is not noticed on a television... Very confused :P
 
You're actually creating the interlaced (or "judder") frame by exporting it as a DV AVI. It has to be 60i, so there's pulldown being inserted, and it's 2:3:3:2 pulldown.

As you've been working in 24p, you can export a 24p file and it doesn't need to be DV. If you want to go to DVD, a 23.976 progressive MPEG-2 file will be what you want to do. It will export only 24p frames and there will be no fifth interlaced frame.

You don't see it on a TV because a TV is interlaced. But if you played it to a progressive TV from a progressive-scan DVD player, you'd see that fifth frame.

Exporting a 23.976 progressive MPEG-2 will allow you to make a 24p DVD. You will no longer have interlace artifacts at all.
 
i use nero vision though. I find the quality when i export to mpeg 2 is beyond garbage. But if this is the only solution....
 
i guess my question is

If i shoot something 24f, import it into a 24f timeline, and export it the way i have been doing, i don't have this issue,

but now that im shooting something at 30f and interpreting it as 24p to attain a slow motion, and i go through the normal work flow, why do i now end up with a different result? Why must these extra steps be taken?
