I am editing a short film that was shot on both 16mm film (about 30%) and 1080i HD (about 70%). The final output is SD PAL DVD projected onto a large screen. I'm new to creating mixed media workflows-can you please send advice about how to handle the two different types of footage, including best sequence settings for FCP 7?
Edit in original format, i.e. 1080i. I suppose your scans are of 2k resolution? You might need to perform some pan&scan further in edit process to combine 1,85(2,40) aspect footage from 16mm with 1,78 footage from HD. So far the best codec to use in FCP7 is ProRes. If you plan only to output for DVD, I suggest you stick with ProRes 422 HQ. Though, if some other options should've presented themselves in the future you can use ultimate weapon, namely ProRes 4444. It'll suffice if you decide to go with film print medium.
