In FCP7, if you added a 1080 clip to a 720 project, FCP7 would auto scale that clip to 66.6%, which is correct, and would give you the latitude of scaling that clip up to 100%. In FCPX, that same scenario does not work? FCPX will auto scale that 1080 clip to 100%? I've looked at all the setting and see no way of changing this. Anyone have some insight on this issue? Any information is greatly appreciated!


Thank you,

    Trying to understand what you are seeing.  Are you saying that the 1080 clip is busting out of the frame in your viewer?  I am not sure if this will help, but I use several pro and prosummer cameras that film in 1920x1080.  I routinely read their files into FCP X and share it as a 1280x720 h.264 file.  I never have to do anything special. Sometimes I mix the HDV format tape-based files with them and even some SD from an older Sony non-HD.  Everything plays happily in the timeline without special attention.  Best wishes.

    At the bottom of the inspector for every clip there is a spatial conform popup. The default is Fit, which is what happens when you put a 1080 clip in a 720 project. You also have the option to Fill, which doesn't apply here as the aspect ratios are the same, or none, which will make the clip display full-sized. Spatial conform is outside the scale value for the clip, though scaling is exactly what it's doing. The new design is unfortunate as you don't know exactly what the application is doing to your media.

    I don't think it's a great idea, especially with 1080i media. I don't see it has being noticeably sharper for the downside of rendering in the project and scaling (conforming) the media to fit and possible creating artifacts when scaling interlaced media and of generating larger original files. Nor do I see any great benefit in very sharp edged, very sharp, high contrast media, especialy if you're going to have to compress it later. If you want to edit and deliver 720p I woulkd shoot 720p. Many broadcasters do it. I personally prefer progressive media to interlaced media, and I don't care for the high data rate and file size of high frame rate media. It has its place for slomo production, but not for general shooting in my view.

    Because it's actually much harder to compress well a very sharp image. The high contrast, sharp edges tend to produce more stairstepping than a slightly aliased image, but if you like it, and prefer it, going ahead, use it.
