720/25pN in avid media composer 25p timeline?

Hello!

i am getting serious nightmares thinking about this:
Recently i shot some clips with the Panasonic hvx 201.
Some of them where just ordinary 720/25p footage, and some were shot in 720/25pN over 50p to create a slow motion right in camera.
Now heres my question:
is it possible to import both of them into one avid media composer/ avid express pro 25p- timeline or are there any errros that could occur mixing them.
I am afraid of the fact that in camera when you review these files some are unplayable and have red file numbers depending on the setting of either 720/25pN (over 50) or 720/25p.
Is it just a normal thing i dont have to be worried about?
Since im not able to test it out today, it would be great to hear some advice before i go on to shoot a scene with this mixed footage again tomorrow.
It is a very unique scene , featuring slow motion, that cannot be duplicated, so it is important to capture the footage savely and in the right way...

I hope everyone got what i mean since my english could be a bit ugly

thanks

alex
 
If they were both shot 25pN, then the clips should appear the same to Avid, because they'll both be 25p timebase clips.

But you're saying "25pN over 50p" -- do you mean that because you shot with the variable frame rate of 50p while recording as 25pN, or do you mean that you shot 25p over 50 (not 25pN, but 25P) with the variable frame rate?

In other words is the timebase of the clip itself 25.000 or 50.000?

As I say, if you shot 25pN, it should be 25.000. But if you shot 25P (which is "over-50"), it'll be 50.000.
 
my avid project will be normal 720/25p.
yesterday, i recorded mixed footage: some clips in 720p/25p and others ( the slow motion ones) in 720p/25pN( recording setup-menupoint) und 50 frames( camera setup-menupoint).
so i used the variable framerate (50 frames).
the slow motion clips played back as slow motion in camera, though i couldnt play the others when i was in that mode, and vice-versa.
now im afraid that, if i´ll be shooting more slow motion clips (with the mentioned 720p/25pN and 50frames), it will cause problems with avid media composer because of this two diffenrent clip "styles".
i cannot repeat the tomorrow shooting, so i am searching for a entirely save way to record slow motion 720-25p footage with the hvx-201 and import it along with the rest of my footage ( normal speed9 into avid..
 
Jimerson is right. There is no 25Pn OVER 50. The N means native so no redunat frames to make a 50 stream.

According to Avid both of these should be able to work in a 720 50p project.

This is Good news for you. NTSC does not do this. 24p and 24pN are not compatible in the same project but your PAL version should be cool.


You can reference their P2 format chart here.

In the future if you want 25p and under/over crank just shoot it all native and do the cross conform on the ouput of the project. Longer record times also.
 
Wait -- I misread you; sorry about that. I thought you were saying you shot the normal-speed footage as 25pN; I guess that isn't what you did. What you actually did is shoot the normal speed footage as over-50, so the normal-speed footage will have the timebase of 50.000 and the slo-mo will have a timebase of 25.000. "Over-50" refers to the timebase you're recording in, not the variable frame rate.

If you want to edit as 720/25p, then your better bet by far is to shoot everything as 720/25pN -- using "Default" as the frame rate in the Scene File menu for normal speed, and 50 fps as the frame rate for the slo-mo.
 
ok guys, thank you very much for your help,
i hope i wrote everything right, its very hard for me to explain this in english :)

i want to edit the clips in 720p/25p avid timeline.

i am concerning about the slowmotion i am about to record tomorrow.
i have read in this forum that slow motion in the hvx can be accomplished by just recording in 50 frames and 25p Native.
yesterday it worked fine for me, the clips were slow motion when reviewed in camera.
now the point is:
is it possible to import normal 720/25p clips AND 720/25pN( with 50 frames) clips in one single avid 25p timeline, so that the slow motion footage( as i saw it in camera) will still be slow an d the rest will be normal .
or simply: native and non-native 25p footage at the same time
or is it more safe to record another way for the slowmotion and fix it in post??
I am so scared of the problems that could occur... :)
 
You recorded the slow motion correctly; it's the way you recorded the regular motion which will give you potential problems in a 25p timeline. Shoot everything as 25pN.
 
could i then just achieve the slow motion without using this 25pN feature? because yesterday i already recorded normal 720/25p footage with 25 frames wich would mix up with tomorrows footage , so is it possible to record it with 720/50 frames and then do it in post in avid?
