Slomo, frame rates & timline

I've been looking around and doing some testing, but need a clearer answer.

30 fps timeline, with the occasional 60fps clip for slowmo. However, when I select the 60fps in clip the change clip speed, it shows 30fps and if I drop the speed to 50% I end up with 15fps.

What would be best practice in DR to drop the speed and keep as many frame as possible for smoother slomo?

I come from Sony Vegas where a 60fps clip is 60fps in a 30fps timeline.

Re-conform under "Clip Attributes".

in the media page if you flag the clip 30fps, one you put it in a30 timeline it will do 50% speed keeping all the frames.

is that what you need?

Uli, it is 60 fps in Clip Attributes, but 30 in the "Change Clip speed" dialog so I'm unsure if I'm loosing 30 frames here?

Walter, how do I flag it to 30fps in the media page?

Thanks you for the replies.

Hi there - I am shooting 2K in 50fps Custom Mode HG7 (XAVI-I) on a SONY FS7 and want to edit in resolve.

I need some of the footage to play at normal speed (25fps), and some of the footage to play in slowmo (50%), on the same timeline.

I want to be able to use the audio tracks of the footage at normal speed, under the video tracks at slowmo.

Is there a way to do this?

Thanks!

Thanks you for the replies.

right click [clip attributes] IIRC.

Thank you. Will test it out tonight again and report back.

I don't have access to my main pc atm, but this is what I have found from what I can see, (I might be wrong)

Changing clip speed works of the fps set in the project, not the actual clip.

So if one has a 60 fps clip in a 30fps project, one looses 30 frames. Drop the speed down 50% one ends up with 15fps.

From what I understand, other NLE's the speed change works on the actual clip fps. 50% drop would give 30fps, making smoother slow motion.

Maybe a workaround it to do the slow motion in a separate 60 fps project and re-import the clips into the main project.

I was wrong! Case closed

Even though the clip speed dialog shows the project fps, the actual clip speed is used.
So dropping a 60 fps clip by 50% in a 30 fps project will have 30 fps, not 15 fps as the clip speed dialog shows.

Anyway, thanks for the suggestions.

Regarding audio, I found that Resolve will play the audio at normal speed for half the length if the clip is re-conformed to run at 2x slo-mo. Not a bad solution if you'd like to use audio elsewhere.

Dear Uli,

Thanks for the audio tip! How do I go about setting up my resolve project so that this happens? Do I make a 25fps timeline, bring in footage at the 50fps (does that automatically play slowly?) and then perhaps 'ramp' the speed to get to 'normal' video speed?

Many thanks

No. As already described here, you go to "Clip Attributes" in the "Media" section and tell the clip to run as 25 fps instead of 50. (or 30 instead of 60 for our American friends).

It works for me with clips from a Sony A7R II and Sony A6300. The audio will play at normal speed and just end after half the length of video.

The best solution for (synthetic) ramping will be getting all the frames into the timeline (as above) and then ramp the speed, preferably with flow motion (DR Studio only).

Well, the perfect solution for sure is a camera with ramping, like a RED Epic…
