That’s the simple answer I was looking for.
Thanks to both of you,

[moldyboot] “you can change the interpret footage settings at any point, not just at import, and it will then effect how the footage is interpretted in comps that use it. try setting the interpret footage setting for pixel aspect ratio of a clip to something different and take a look at how it looks in a comp, then change it back and take a look again (make sure the aspect ration correction option is off in the preview)”

[Ed Dooley]

Sorry, still a little confused. If you import a clip and interpret footage as having fields, AE separates the fields.
On output, you select the field order and AE puts it back together. Does it matter when in the process you Interpret Footage?
For example, if you forget to Interpret and put a clip in the timeline, add effects, scale, and change position, then go back and
interpret footage, does it still help, or does it need to be done before editing the clip? In my example, I unlinked a clip, then
relinked to AE with a de-interlaced version of the clip, will it accept the newly changed Interpret Footage settings, or maintain (or try to maintain) the original settings, since the original clip is already in the timeline?

[Mylenium] “Footage interpretation is done in the project window and thus all clips used in your comps will inherit it, since the only represent references to the project window/ assets. It doesn’t matter how you tweaked your clips in the timeline, AE takes care of everything. Some effects may look slightly different, though since the pixels they use may differ between progressive and interlaced footage.”

I’m assuming these are video clips that are flickering, not stills?
Use the Flicker filter.

There might be something else going on. I have just had the same thing happen with a corporate client.
He read the version number right from the “About QuickTime” window and has 7.1.3. He couldn’t play an
MPEG-4 compressed .mov in Compression Master. Can’t figure it out yet. He could open an MPEG-1 (which looked
terrible) and a SV3Pro QT. Everyone else viewing it on different machines, PC and Mac could open the MPEG-4.

The problem we have in using Windows Media for draft reviews for PC users, is that it’s not
easy to scroll through the clips to discuss specific edits. QT is king for that (now if we could only figure out what’s up).

Just had the same issue appear on the Dallas FCP list. I referenced the
Apple support page that talks about it:
>>>If your server contains high-bandwidth usage data files, such as large video, graphics, or audio files, you may want to weigh the benefits of using journaling against the performance needed to access your data. In most cases, the impact of journaling upon data access performance are unnoticeable to users, but its implementation may not be practical for servers where data access demands outweigh its benefits.<<< I got 2 responses that said Apple engineers at NAB told the respondents that journaling doesn't affect performance enough to not use it. I personally don't use it for my media drives because I want every last bit of performance. I *never* capture to my OS drive because it's running the OS and a number of apps at one time. The extra throughput needed for media can produce dropped frames (and I do uncompressed video, not just DV). Ed

Wait a minute, don’t do it! This thread is a few days old so I forgot you have 24P footage. Of course the P
stands for Progressive, no fields!

[Ed Dooley]

You mean Interpret Footage? Yes, you should use it for the best quality. Here’s what Adobe says:
>>>If you want to use interlaced or field-rendered footage (such as from NTSC video) in an After Effects project, you will get the best results if you separate the video fields when you import the footage. After Effects separates video fields by creating a full frame from each field, preserving all of the image data from the original footage.<<< Ed

Sorry for confusing the issue with the 1080i Preset comment. I sat down to the COW from reading “March”
at 11:PM (after a long day!). I was trying to say that AE7 deals with *HDV 720* footage through a preset and by
just selecting that everything should be fine. And as Shane has reported from experience, that’s the case.
Ed

[Ed Dooley]

Not trying to compare here, but you can also try Compressor 2s Advanced Format Conversion
(not the regular de-interlace filter!). Do a search of this and maybe the Compression Techniques
forums, I know I spelled out the workflow (at least once).
Ed

[Ed Dooley]

What version of AE are you using? AE7 has a native HDV 1080i60 preset, which presumably
sets the aspect ratio correctly. I’m guessing if you have an earlier version you have to set it
manually.
