  • Different FPS??

    Posted by Anna Holck on November 17, 2014 at 10:40 am

    How do i edit two different video clips, with different FPS, without one of them to loose quality, or size?

    Let’s say i want to make a music video, and some of the clips are in slowmotion (50 FPS) And other in (25 FPS) And i have to edit them.. How the heck do i do that??

    Do you edit the different FPS Videos in different sequences? Or do you edit it all in one sequence, if so how? And if i should edit it all in one, which FPS should i use for the entire Sequence?

    And do i have to change anything? And if so, is it the video or sequence FPS i have to change?

    Thank you so much in advance! And sorry if it is all very confusing. 🙂

    The easy way is to right click on your clips and go to modify > interpret footage > assume this frame rate and type in 25 (if you’re working in 25). this will make all your 50fps stuff play back at half speed (which is presumably what you want).

    The difficult way is by transcoding all of your footage to 25 outside of premiere but this will result in loss of quality and artefacts on the footage.

    But when i change the 50 FPS to 25 FPS, will it then be the same as if i just recorded the original video clip in 25 or will it still work for slowmotion, meaning will it still be the same as 50 FPS, even though it is changed to 25? Because otherwise i don’t see the point of shooting it in 50 FPS in the first place, if you’re just going to change it to 25 later.

    Thanks for answering! 🙂

    Oh and also, is there anyway that you can change FPS (Interpret) without it being made slowmotion or fastmotion? (depending on what you’re going to change it to) Cause i would like to do that manually in after effects, after FPS is changed.

    NO need to change it if you want it normal speed. Simply have a sequence with the settings you want, with the frame rate you want, and cut in the off-frame rate footage. If it’s 50fps, and you drop it into a 25fps sequence, the footage will be 25fps…every other frame will be removed. No quality lost.

    REALLy easy.

    It wont be the same result, it will be half the speed! And as Shane said above, if you want it at normal speed just drop the 50fps footage into a 25fps timeline and will be good. If you want to use the same bit of footage at both normal speed and half speed then you can make a copy of the clip and ‘interpret’ frame rate on one and not on the other.

    Yes i woud have just dragged it in the 25 FPS sequence with the other videos that are 25 FPS, but when i try to there comes a mismatch warning up? What should i do there?

    ‘keep existing settings’

    But then it will be zoomed in or out (Can’t remember which one.. I’m not so good with FPS)

    ah, so it’s 720p? right click and ‘scale to frame size’

    But won’t it loose quality when you do that? in any way ?

  • Mark Norgate

    it wont lose any quality as the 720p is less good quality than 1080 anyway, so you’re “up-res-ing” it higher than it actually is. it would be different if you were to down-res 1080p footage to a 720p sequence.
