Video Playing Back at 1/2 Speed - 1DX m2

DPhotoR · Oct 8, 2020

Long, long time reader - First posting.

Note: I am a photographer. With that said, I've started capturing video (1DX m2). When I pull it off the card and play it on my computer (2013 MacPro via QuickTime) it plays back at half speed. I've captured video on several other Canons but never experienced this. I figure I can change it in Final Cut Pro. However, at this time, I need to share the video, unedited with a client and don't want it to appear at half speed. What setting did I activate on the camera?

Camera Settings:
1920x1080 119.9fps
For editing (ALL-I)
MOV/MP4
Movie rec size
24.00p - Disable
High Frame Rate - Enable
Firmware Ver 1.1.2

The file is massive and most computers can;’t play it without stuttering in its native format. You need to export it into another CODEC that will vastly reduce its size and mean anything can play it.

You have shot it at 120FPS so it will playback at half speed (assuming your default playback is 60FPS). I guess old QT 7.x could not adjust the speed, when playing the files straight out of the disk, but the newer QT (ver. 10?) can do it. i cannot verify without a Mac. Better give it a try.

I uploaded the video to FCP and exported it to Vimeo - video plays at half speed.

If you shot as 120fps it will play back at 1/4 speed naturally, it won't playback at 1:1 speed unless you put it in a 120fps frame rate timeline and then export it. But few things can play 120fps timeline video correctly.
