Coming from Avids Media Composer I am used to apply an effect in timeline and then right click and render to final format. After I rendered the clip it always plays back smoothly.

In Resolve Studio 16: If I apply a complicated OFX effect in Edit, and the effect does not play back smoothly, how do I render this clip?

With simple FX I just press play and Resolve just hops from frame to frame until the line above the clip is blue and it plays back (sometimes not really perfectly smooth).

Must I go to Delivery or can I do a final render of the effect, so it plays 100% smoothly in Edit?
How?

What is the normal workflow if clips with OFX need to be rendered, so they play back smoothly in Edit?

Go to Settings, the little cog bottom right and then head to Master Settings and then scroll down to Optimized Media and Render Cache. Change your Render Cache format to say ProResHQ. Then select Automatically Cache Composites and Transitions in User Mode. Enable Background Caching. Hit Save. Now go to Playback-Render Cache and set it to User. That should cache your files and give you better playback.

If you prefer user control about renders in timeline:

- check Playback/ Render Cache / User
- right click on clip(s) in timeline and check Render Cache Color Output
- sometimes needs playing clip from beginnig to end with Show All Video Frames (check under 3 dots menu in top right corner of timeline viewer)

Cache is the phrase you want to search for in the manual.

Thx.

Playback -> Render Cache is now set to User.
When it was set to smart it rendered everything that was playing, now I have to select all the clips I want to cache?

And even when I have a blue line above the clip it doesn´t play back smoothly. And I can´t scrub/move in the in timeline as I can in Avid. When everything is rendered in Avid you can move the cursor over the timeline with no stuttering at all.

My Render Cache settings are DNxHR LB.

My system is: WIn 8.1 Pro, I7-4790 @ 360Ghz, 32GB RAM, GTX 970

Is 4K stuttering normal after caching?

First of all, Windows 8 is unsupported, you should get W10. And your CPU clock speed seems very futuristic…

Switch your timeline to HD and see if it improves. You can always switch back to 4K before final render.

I don't use a windows system so I can't speak about it but I have no issues playing back 4k when I Cache.

So, my Render Cache Format list does not include ProResHQ as an option. Is there a reason why, and is there a good resource as to understand what all the options are and particularly why one would choose one over another?

There is no ProRes on PCs, go for the one you highlighted.
