ProRes 422 setting and rendering
on Jun 7, 2010 at 7:59:21 pm

I shot a project last week on P2 cards (1920x1080 30p avcintra 100). I ingested this morning converting the clips to ProRes 422 on ingest. I dragged a clip to my new sequence and clicked "yes" to have the settings for the timeline be the same as the clip, but I still have to render the clip. when I check the settings they seem to be exactly the same. In "safe RT" mode I get a red line. In "unlimited RT" mode, I get the orange line.

the one thing I notice, is when I open the settings window for the sequence, the aspect ratio listed for frame size is "HDTV 1080i (16:9)" even though we shot 30p.

This is not really impeding my edit, but I'm confused as to why this is happening.

fcp 7.02/mac OS 10.6.3/8 GB RAM/2 x 3 GHz quad-core intel xeon

thanks,

Mike

On the clip in the timeline, right click and choose 'remove attributes'. On the video side of things, does FCP allow to check any of the check boxes?

In the browser, scroll to the right and report the clip info, and then take a screen shot of your sequence settings (command-zero to being those up).

Jeremy-

there are no video attributes to de-select.

As far as clip settings and sequence settings, they are the same (listed below)...

1920 x 1080, 29.97, apple ProRes 422, square pixel aspect, no field dominance

thanks,

Mike

Do you have a RAID to play these back from?

Also, tell me about the ram in your system. i know it's 8Gigs, but how is it configured?

yes...footage is captured to a Dulce RAID (not sure of exact configuration/client site) but it is very fast and have never had issues with it.

RAM is 667 MHz DDR2 FB-DIMM.

thanks again...

[Michael Williams] "RAM is 667 MHz DDR2 FB-DIMM. "

Sorry, I should have been more specific.

What manufacturer(s) and how may DIMMs are full?

according to the System Profiler, it looks as though there are 8 slots with 1 GB of RAM in each. for manufacturer, it says "0x830B." not sure what that means. if there is some other way to determine, I can check, but I don't know other than that.

Yeah, that seems about right.

I am sure you trashed your prefs? You should be able to crunch through this footage with no problems.

Did it ever work?

this is the first time that we have used the 30p setting instead of 60i and I'm guessing the problem lies in that issue. even though all the settings appear to be the same, my guess is that the sequence is set for interlaced and I can't find a way to manually correct it.

any ideas?

thanks for your help.

Please post a screencap of your sequence settings. It will help.

Are the clips set to field dominance of none? Is the timeline?

What codec is listed in the clip settings? how about in the sequence?

As far as I know, pretty much ALL 1080 video is interlaced, even footage shot as progressive scan. There are those cameras that will shot true progressive scan at 1080, but they cost about as much as a 2010 Corvette ZO6.

This is nothing new: standard-def 30p video also contains interlacing. Think Panasonic DVX-100 cameras. Same deal -- progressive scan, but interlaced video.

So the Browser info you have is correct: it's 1080i, but with no field order (incorrectly called field dominance in FCP).

[Dave LaRonde] "As far as I know, pretty much ALL 1080 video is interlaced, even footage shot as progressive scan."

It's transported over an interlaced stream, but in the computer and on the P2 cards, it's progressive and you can treat it as such in FCP.

Yup: just like progressive-scan SD video shot on a DV camera. Match the field orders in footage and timeline to NONE and life is good.

we shot with the Panasonic 3000 in the 1080 30p setting but perhaps it goes to P2 interlaced or perhaps it gets converted to interlaced on the ingest/transcode to prores 422?

all beyond my expertise...I'm just trying to edit without rendering.

No. What Dave said is just confusing you (sorry Dave).

For all intents and purposes, you shot 30p and you can edit 30p. We just have to find where your settings aren't matching. Please post a screen cap of your clip settings and your sequence settings.

Jeremy-

I don't know of a column in the browser that shows whether a clip is progressive or interlaced. So, I'm not sure how to get an image of that to post. If you know, please post and I will do it.

Right click on one of the clips in your browser and choose Item Properties > Format. Then take a screen grab of that. Then open your sequence, hit command-zero to bring up the settings, and take a screen cap of that.

Yep, that all looks correct. Thanks.

First, the easy stuff.

Quit FCP, trash prefs and delete your thumbnail and waveform cache.

not sure which part of that did the trick, but it seems to be working properly now.
