  • Transcoding 50fps to 25 without it footage being in slow motion.

    Posted by Romina Rey on October 20, 2016 at 4:57 pm

    Hi I need to transcode raw footage shot at 50fps for a project that will be entirely at 25 fps and the editor wants all the footage to run at regular 25fps and not slow motion.
    What is the best and fastest way to do this?

    Thank you in advance for your time and I hope to hear from someone soon.

    Thanks for your response. I believe it’s interlaced because it was shit 1080/50.
    I am told that is most likely interlaced but I am not sure.

    Would you be able to tell m both methods while I get more information.

    I don’t know what would be the easier way or if there is a way to do it in mpeg streamclip or premiere or in another editing software

    Okay so I’ve just received the footage. They shot with an Alexa Mini and when I import the footage into premiere the footage was shot at 2944 x 2160 at 25fps but it’s playing back in slow motion and they need it in 1080 25fps Apple Pro ResLt not in slow motion. I’m baffled by how it can be in slow motion if the footage reads 25fps.

    Is the only way to bring it into a sequence and ramp up the speed at 200 and export?

    Yes I dragged and dropped so that the same specs would be on the sequence and even when I play it in QuickTime it reads 25fps but plays in slow motion.

    Because the camera recorded the high speed footage in a 25fps container. The Red cameras do a similar thing.

    Hi Romina,

    If the source is 50i, and you export as 25p, that should work without any other steps, will be deinterlaced during export. Try a sample first and make sure it looks good though. I’ve done this with 60i to 30p before.

    Thanks
