Mixing frame rates and selecting a new frame rate for additional footage.

[m0rr1s3]

I am working on a series of videos that were shot in multiple frame rates and resolutions. I need to shoot  more interview footage and it was suggested I record it in UHD 2160/23.98. I am concerned that it won't mix well with footage that has already been created. Here is the footage I currently have:

UHD 2160/59.94p - Used for cutaways most likely for slow motion

1080p 29.97 - older existing footage to be used for cutaways that also may need slow motion

1080/59.94p - interview footage. (Wish this was UHD for cropping purposes in case I need 1080 output)

Any suggestions on what resolution/frame rate I should use for the upcoming interviews? I would like to use UHD for cropping purposes but not sure what would be the best frame rate. I am also not sure what frame rate to set the timeline for Adobe Premiere editing. The output resolution most likely will be 1080p but 720p is also being considered.

My two cents:

You will need to consider the quantity of existing footage versus the additional footage you are going to shoot. If the quantity of the existing footage far exceeds the additional footage, then you want to stay with those frame rates.

Also, you did not say what frame rate you are planning to master and deliver the project in.

If it were me, based on your source material, I would master the project in 29.97, and I would not shoot the additional footage in 23.98, but either 29.97 or 59.94.

The source material you have now with 59.94 and 29.97 frame rates will play well together on a 29.97 timeline. The additional footage, if shot at 23.98,  will have a noticeably different frame rate cadence.

Based on your answer it would make sense to  output the final in 1080/29.97 or 720/29.97. An outside company recorded some of the footage and completed one of the videos. Their completed video is 1080/23.98. They are also sending us some interviews shot in 23.98 that will need to mix with the interviews I record. Any reason to record interview footage in 59.94 since there is little movement? I am concerned how their 23.98 interviews will mix with ours with the different frame rates.
