Hello, I get projects from other editors and sometimes the interpolation is not maintained so the clips are slipped to a different section on the timeline. For example, if the footage is shot in 60P and the editor interprets the clip as 24p to make it slow motion, then they send me the footage and the project file and the clips are not showing properly and don't remember the inertpolation that the editor assigned to them.
Also, if the speed is adjusted it doesn't show the clip at all. And then sometimes it shows this...
It's honestly better to not interpolate the footage and to just slow it down in the timeline. It's kind of one of those best-practices when sharing. Because yes, whether it's you or another post production software, the interpolation in Premiere is not usually going to go well for others in the pipeline. Footage shot at 60fps can be slowed down to 40% speed in the timeline to achieve the same result without modifying the source interpolation.
I'm with Phillip. I work with a lot of colorists, who get their project in from FCP, Premiere, or Avid, and no matter the app, they have problems with this. Which is why they require an H.264 full encode of the sequence that they put over the track to be graded, so they can manually match both zoom/size/postion and time changes.
And unfortunately, a lot of it does end up being manually matching.
So you might request they also do a low-res H.264 export of the sequence and include that for you to check things out on.
