Replace imported footage? (A-la After Effects)
In a nutshell: I’ve got several [i]dozen[/i] extensively edited projects (cuts only) and I wish to replace their imported videos with alternate videos of the same length. This doesn’t seem to be handled in an intuitive way in PPro (unlike AE), so I’m after whatever the solution may be.
In detail: I have recently discovered that most of my footage is YUV but exceeds the luma spec above 235, all the way to 255. Not an uncommon phenomenon, but Premiere Pro handles such things very badly. I have had to go the route of using an Avisynth script which converts the (DV and HDV) videos to RGB without expanding the values, thereby saving the whites rather than crushing them. I’ve gotten Premiere Pro to import the AVS files just fine. But replacing one imported video with another seems to be something PPro doesn’t do with a simple right-click.
What are my options? How do I get this to work? Does Sony Vegas handle this better?

It helps if you state your version of premiere pro. CS3 has a superior file replace system to even FCP! OMG! If you understand it you’ll have no issues. You must be conscious of the matching frame from the clip you have in the source and the one in the timeline. You then replace the clip by right clicking on the timeline clip and select replace match frame. Any effects, animations you have on the original clip in the timeline will now have those attributes too. Obviously you need to import the replacement clips and then replace them manually one at a time.
If the updated clips are exactly the same length and there are no timecode differences to the originals then you can offline them in the project panel and relink them to the updated versions. All uses of the clips in any timeline sequence will be updated.

How many editors does it take to change a light bulb?

Sorry, it was PPro 2.0.
Thanks to your suggestions, I was able to at least get as far as turning the imported video “offline” and using “link media” in an effort to replace it. This time things broke down because of a complicated matter.
I’m actually replacing the videos with Avisynth scripts that use the same exact videos, just with the following modification:
ConvertToRGB(matrix=”PC.601″)
The point is to bypass PPro’s poor handling of non-compliant YUV. Unfortunately, I have only now discovered that Avisynth does not spit out the video with its audio. And of course Premiere Pro complains about that.
So I guess now what I need to know is the syntax which will tell Avisynth to keep the audio channel, since it is evidently not kept by default.
