24p Native and Avid

I used the HVX200 in 24p Native to shoot some slo-mo for a 35mm filmTV spot.
The client and I agreed that shooting 35mm film at 60fps to get a good "Bronc Riding" shot could blow out the film budget.
We used a bunch of 4gig P2 cards and a P2-Store and the files were eventually moved to two external drives.
The Ad Agency/Client uses a large Post and Tranfer house. Their editor sent the following message:

I'll see what I can do to use as much P2 as possible. But we've recently had three producers
come through with P2 shot at 24 (23.97). It's been an unpleasant discovery for each.

Both Avid and Final Cut Pro can bring in the footage.

But it can't be viewed on any client monitor (it only shows up on a computer monitor...there
are no screens manufactured that will display 720x1280 @ 23.97).

Once edited, there are no tape machines manufactured that will record 720x1280 @ 23.97.

I assume you discovered that you could not even playback and view the footage in the
camera viewfinder as 720x1280 @ 23.97.

So there is a basic problem here.

Everything needs to be converted to 720x1280 @ 59.98.
Then it can be edited and Master recorded to tape normally.

But the conversion process involves recording it out of the 24 project to a massive QT as 60.
Then opening a 60 project and importing the QT.

On a one minute clip, the process takes 10 minutes to export and another 10 minutes to to
import. Three minutes of footage takes an hour at rate card $200.00. Theoretically, each 30
minutes of footage would take 10 hours and cost $2,000.
I don't know how much footage there is but what I will do is import everything as 23.97.
Then make selects and output only what may be usable as 59.98.
Hopefully 10 minutes worth will only be a half day process.

We've studied the Panasonic website and no where does it explain the workflow for 23.97
specifically.

P2 shot as 59.97 looks great and works well within current post facility environments.
It tapes up more disk space but is user friendly throughout the production/post process.
You have the freedom to shoot at 23.97...it's just time and money. And the film look
probably becomes a mute issue after the image gets jerked around during the conversion
process.

Just thought you'd like to know.

You seem to be very alert to the P2 technology...if everything I've written doesn't make sense
to you...we could be crazy...please let me know. (end of editor's message)


I am a shooter not an editor. Would someone please help me get him ontrack with the P2 workflow?

I did tell him that we viewed footage with the camera during the shoot in 24PN. He has the backup drive, the footage is fine.

The Avid edit system is Adrenaline and he works with Varicam and Cine-Alta footage every day. The P2 footage will just be a few short cuts in the final 35mm spot, which will be released in standard def.

Thanks in Advance

 
Just shot a technical test run for ESPN with 7 HVX's all shooting frame rates all over the grid. We shot from 12fps - 60fps on all these cameras - I'm taking a break from editing as I write this. We have had no issues what so ever and I'm watching all of these frame rates on a highdef monitor monitor no problem. The frame rate shouldn;t be an issue either because the filnal product will have to be output at 29.97 for broadcast delivery in the US anyway (i'm sure that someone out there is doing otherwise - but I have yet to see it in broadcast). Both apple and avid have 23.98 fps work flows and more specifically HVX workflows.
Here is Apple's
images.apple.com/finalcutstudio/finalcutpro/pdf/20060302_FCP_Wkflw.pdf
Also it is 1280 x 720 and 23.98 fps - rather than 720 x 1280 and 23.97 fps

It seems like there is a lot of confusion of the process overall on the editor's part
 
As far as viewing and editing, goes that simply isn't right. I shoot almost nothing but 720p 24pN and I never have any issues with it in Avid. It's the one mode every seems to work perfectly in. I don't get why he just doesn't bring the 35mm stuff into the same 24p timeline, edit it with the 720 stuff, and then put it on whatever tape he needs.
 
We ran into this problem. The producer I am freelancing for uses avid and you can't mix frame rates. In FCP, you will have to render, but you can still at least do it. You can even load it into the preview monitor in Avid, it just comes up and says some error about the different frame rate. So what we have figured out...... this might help, or it might not. We are editing on at 30i timeline mixing dv footage with some of the HD footage i shot. Seeing we could never get it to use the 24pn footage. We shot 30pn which runs at a framerate of 29.97 so it was able to be cut in with dv footage easliy. Not sure if this helps anyone, but it helped us. You can overcrank and undercrank in the 30pn mode and for normal shooting we shoot at 24 frame rate in the 30pn time base so it was gold for us!
