50fps to 25fps without loosing frames?

[Ivan Myles]

“Trim the first frame” means edit the clip to start on the second frame.

“Slide the clip to frame zero” means move the edited clip to the beginning of the sequence (Frame 0).

The following is a more detailed explanation. Consider a 50fps clip that is one hundred frames in length. In a 50fps sequence the frames will be displayed as follows:

F00 F01 F02 F03 F04 F05 … F96 F97 F98 F99

When inserted into a 25fps sequence, Premiere Pro automatically skips every other frame:

F00 F02 F04 … F96 F98

We want to display all the footage from the 50fps clip without skipping any frames. Here are the instructions from my previous post:

1) Create two 50fps sequences of the clip (A and B)

A: F00 F01 F02 F03 F04 F05 … F96 F97 F98 F99

B: F00 F01 F02 F03 F04 F05 … F96 F97 F98 F99

2) In one of the 50fps sequences (B), trim the first frame…

A: F00 F01 F02 F03 F04 F05 … F96 F97 F98 F99

B:        F01 F02 F03 F04 F05 … F96 F97 F98 F99

[e.g. In Sequence B edit the clip to start on the second frame (F01)]

2) … and slide the clip to frame zero

A: F00 F01 F02 F03 F04 F05 … F96 F97 F98 F99

B: F01 F02 F03 F04 F05 … F96 F97 F98 F99

[e.g. Drag the clip in Sequence B and move it one frame to the left]

3) Create a 25fps sequence and nest the two 50fps sequences above each over

Track2: F00 F02 F04 … F96 F98
Track1: F01 F03 F05 … F97 F99

[Notice that every other frame is removed when the 50fps sequences are inserted into the 25fps timeline]

4) Reduce the opacity of the upper sequence so that both clips appear

Now the final output will have two frames displayed at the same time: F00+F01, F02+F03, F04+F05, … F96+F97, F98+F99.

Hi Ivan, Im fron Argentina. I make wedding films, the problem is that my project was in 1920 x 1060 x 60frames, because of the title, but my footage was all in 25fr. So when i export in .mp4, the final video is with 60 frames. I have no longer the original clips and don’t have the project, I need to put the video in 25 frames so my clients can wach the videos on their tv. Thank you!!!

Hi Ivan,

I have several clips that I need to transcode from 50p to 25p without making them slow-motion. What would be the best way to accomplish that. The editor wants them in ProRes LT but wants to keep the speed and like I meantioned doesn’t want them in slow motion.

Thanks for your time and I hope to hear from you or anyone who can help soon.

Hello Ivan,

I’ve just read your comments about 50fps to 25fps and I’m sure you’ll be able to help me on this problem :

I shot with a RED at 50fps (PAL) and everything is in slowmotion as requested. BUT, I would like to play some of my footages in real speed (25fps) now… And when I double speed in premiere CC, the movement is not totally smooth.

Is there any solution ?

Best regards,

U
