I am trying to build a video using clips with varied frame sizes. I have IPhone footage that is 1280x720 and DJI Drone footage that is 3840x2160. The frame rates are the same 29.97.
If I start with a sequence using the DJI footage frame resolution (3840x2160), Premiere Pro will not allow me to add the IPhone clips (1280x720) If I start with a sequence using the IPhone footage frame resolution, (1280x720) Premiere Pro will allow me to to add DJI footage clips, (3840x2160)
I want the final project to have the higher resolution. I have done this before and not had a problem building a sequence with mixed frame resolutions. I fully undersatnd that the size of the varied footage is either smaller or larger when used in the same sequence. Not sure what is happening this time.
I tried building a sequence as you suggested. I had the same problem. I built a sequence with the 1280x720 IPhone frame size. I added the IPhone clip. Then adjusted the sequence to the DJI frame size 3840x2160. I added a DJI clip and then tried to add another IPhone clip. The DJI clip added no problem, but I was not able to add the new IPhone clip.
Here are the properties of the 2 clips
DJI Type: MPEG Movie File Size: 5.55 MB Image Size: 3840 x 2160 Frame Rate: 29.97 Total Duration: 00:00:00:13 Pixel Aspect Ratio: 1.0 Alpha: None Video Codec Type: MP4/MOV H.264 4:2:0
IPhone Type: MPEG Movie File Size: 17.06 MB Image Size: 720 x 1280 Frame Rate: 29.98 Source Audio Format: 44100 Hz - Compressed - Mono Project Audio Format: 44100 Hz - 32 bit floating point - Mono Total Duration: 00;00;16;08 Pixel Aspect Ratio: 1.0 Alpha: None Video Codec Type: MP4/MOV H.264 4:2:0 Variable Frame Rate Detected
I just noticed the DJI has a frame RATE of 29.97, as expected, but the IPhone clip has a frame rate of 29.98. I've never seen this before. IS this the cause of my issue? IF so is there a work around?
