shot some footage and some of it comes out jittery. especially when i shoot handheld. this is after i edit and render. i usual shoot 24p advanced. was wondering what are the difference between 24p and 24pA. and should i should regular 24p to get rid of the jittery footage.
 
24p if you are editing in a 29.98 timeline.

24pA if you are editing in a 23.976 timeline.

Thats all that matters.

Does this mean if I'm still using Premiere Elements (on my way to PPro), which does not have a 23.976 timeline, only the 29.98 timeline... then I can still edit 24p footage properly? As long as I shot in 24p (not 24pA)?
 
Yes -- shoot 24p standard, and edit as 29.97. It's not "properly" in the sense that you're editing 24p NATIVELY, but you're doing it the way it's been done for decades.

If you have the ability to edit natively in 24p, go for it. But if you don't, just go with 29.97.
 
ok I shot in 24PA just now and used the 24p project setting in premiere pro 2. captured and all, and when i drag it in the timeline, I am still getting squiggly lines when the camera moves. I made a mpeg 2 file and it is jittery and looks interlaced.... should I just not even bother with 24PA, is 24p standard less quality though? I mean I guess if I wanted a film look I would be making a 24p dvd but can this be done with 24p standard and just editing in a 29.97 timeline so I dont have these issues?
 
What do the clip properties say? The 24p timeline in PP 2.0 should remove pulldown for either 24pA or 24p standard footage.

You can theoretically make a 24p DVD after editing on a 29.97 timeline, but I would very much recommend against it. The results will be . . . inferior.
 
it said the frame rate for the clip was 23.975.

Can I still get a film like motion and look on a final dvd if I just use 24p standard and output a 29.97 dvd? It is the only option that is not bringing me these squiggly lines and problems...
 
I'm not sure what you mean by "squiggly lines." Can you post a screen shot?

It's possible that it might be a result of shooting in "Thin" mode, or by moving the camera too quickly for the 24p cadence.

If PP is reading the footage correctly, as it appears to be, then you shouldn't be seeing any interlacing.

You'll still get a film-like motion by shooting 24p standard and editing in 29.97 -- in the footage, anyway; any text or other motion you may add will look more video-ish. If you make a 29.97 DVD, it will still look film-like, and probably fine on a standard TV. But if you watch it on a progressive and/or HDTV through a progressive-scan DVD player, you'll see interlace artifacts.

Much better to shoot 24pA, edit in 24p, and make a 24p DVD.
 
After a long time last night I figured some things out...

The squiggly lines were only in the preview window. I changed the quality to DRAFT and they went away. Im thinking it was because such a high quality file being compressed in the small preview window was causing that... i dont know for sure.

As for exporting. I was in my 24PA timeline, and I exported an mpeg2 at 23.976, but I have to export it as LOWER FIELD with no pulldown. If I export as progressive or anything besides that, I get interlace artifacts. And even in the preview window if I got to 100%, I still notice small interlace artifacts when the camera movies, no big deal, barely noticeable when the preview window is at "fit" and it does not affect final output file if I do it as lower field.

Like I said I shot 24pA, used the 24p setting in premiere, the clip was recognized as 23.975, so I dont know what was up with exporting problems I had but it seems if I select lower field, no interlaced artifacts are present. Has anyone else had these problems?
