To upscale HDV to 1920×1080 or not?
Here’s a workflow question. In a ProRes 1920×1080 30p FCP sequence should I be upresing Canon HX-A1s HDV clips (from 1440×1080 to 1920×1080) for the timeline where they are presently scaled at 133%?
Or, for some reason, leave them the original size (converted to ProRes 422 at 1440×1080, 133% in the sequence) and export it the final edited sequence this way?
If it makes a difference, the sequence also has Canon 7D footage which is native 1920×1080.
Any help is much appreciated.

If I have this right, FCP is not actually scaling the footage 133% even though the motion tab says so. When FCP distorts the footage to get the correct aspect to 16:9 from the anamorphic frame of the 1440 clip, it does the math on the vertical scale, effectively shrinking the image vertically, then it has to scale it back up to fill the frame….but in the end, all it has done is stretched the footage horizontally across the frame. You don’t lose resolution doing this. So I think you’re fine. However it might take less processing if you add effects etc on these clips but you’d have to test it.

Thank you for your response Rich. The logic of what you’re saying really makes sense. It would be great if there was no need to upscale the HDV footage in FCP to 1920×1080 without losing resolution. The clips are converted to ProRes so I’m wondering if that also takes care of the processing concerns adding effects.
Perhaps I should have posted this question on a Canon forum because is it possible to get a final consensus?
