  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Speed issue in Premiere CS6

I'm a complete newbie with R3D files, and Red workflow in general, so I apologize in advance if this question is common knowledge. I've done some research, but can't seem to come up with anything.

A friend and I have just completed shooting a short on the Scarlet. Almost everything was shot at 4K 24p. When I bring the footage into the timeline, which is set up as 4K 24p, some of the clips appear slightly sped up (like when 18fps footage is played on a 24fps projector). Has anyone else had this issue?

I've checked the clips in Redcine and they look fine. When I bring them into Premiere, though, this speed up thing happens, and it's like that when I output, as well. It isn't happening on all of the clips, only a few of them, and it seems completely random which ones are. They are from different cards, different shooting days.
 
Drag one of the clips into the new item icon and it will conform the timeline to the clip.

Are you playing back the clips at half or quarter resolution.

What nvidia card are you using?
 
Was the camera project setting at 29.97fps? And you then inadvertently went to varispeed in order to get 24fps.
 
I tried doing a new sequence and dragging one of the "offending" clips into the sequence, and letting Premiere conform the sequence to the clips settings, but it still came up with the same problem.

I'm playing clips at 1/8th resolution. I've found it works best for me.

Upon looking at the camera setting, it looks like this is what happened. We didn't record any audio with these clips, it's all just B-Roll. Is it safe to say I can just slow them down in post, then?
 
Hi Stewart,

Not sure how you were planning on slowing down the footage but just wanted to make sure you know the correct way to do it. Rather than manually slowing down clips on the timeline, you should be just re-interpretting the offending clips to conform to the correct frame rate.

To do this select all your offending clips (or even all of your clips) in the project panel. Right click > Modify > Interpret Footage. In the Dialogue box, select "Assume this Frame Rate" and set it to 24.00 fps. This will tell Premiere to interpret the footage as though it was shot at 24 frames per second rather than the 29.97 timebase in the metadata of the clips.

Brad, Thank you so much for this info! Like I said, this is my first time dealing with R3D, so that information just saved me a lot of time and frustration. Thanks again!
