Moving from 2k to 4k timeline

Not found any suitable solution for this so I hope someone can give me a tip. Problem is that I have a project in a 2K timeline which I want to move to a 4K timeline to be able to render in 4K
There doesn't seem to be any obvious way of doing this (eg export/import) without completely re-editing the entire project?

Maybe exporting a EDL or XML of the timeline in 2K and conform again in a 4K timeline?

You just need to change your timeline resolution to 4K

Thanks Paul. Which is what I looked for but couldn't find. Could you enlighten me?

This is a fundamental setting on Project Settings.

Please read the extensive use guide. Chapter 1 probably covers this.

Please assume that this has been done and tried otherwise I wouldn't be asking.

Yes you can change the project settings but sadly that doesn't affect existing timelines, hence the problem and my question

"Please assume that this has been done and tried otherwise I wouldn't be asking."

"Which is what I looked for but couldn't find."

Which of these applies? And as Peter said, it's covered in the manual, early on.

I see. What page and section, specifically?

Chapter No. 1 is fundamental. Do not hesitate to read it and read it completely.

Page 65 of the v14 manual covers Timeline Resolution in detail.

The question remains then... If my footage is 4K and I want to be able to render in 4K, must the timeline also be in 4K ?

Logically the render should be independent of the timeline resolution but I have yet to find anything which confirms this in Resolve.

If this is indeed the case then what is the point of having the option to set different timeline resolutions?

Observed behaviour:

Using 4k footage in a 4k timeline, rendering to 2k/HD gives better quality than using 4k footage in a 2k timeline, rendering to 2k/HD.

And:

Editing/grading 4k footage in a 2k timeline massively improves performance compared to using a 4k timeline. This is expected, since 2k is just 1/4 the amount of pixels of 4k to push around.

DaVinci Resolve is resolution independent which means that for example power windows and tracks will scale with changes in timeline resolution. This allows us to work at 2k and deliver in 4k or higher.

Solution to "quality problem" now: change timeline resolution just before going to Delivery page when all work is done.

Suggestion: it would be nice if Resolve could make sure that quality remained equally high regardless of timeline resolution, by always referring back to source clip resolution on export. I don't know why this doesn't happen. Or if it does happen, why the scaling from the Delivery page is of less quality than changing the timeline resolution as an intermediate step first.

It is as if the Timeline Resolution effectively becomes "source clip resolution" as far as the Delivery page is concerned.

Yes. Work in 2k for performance but switch over to 4k just before exporting.

Personally, out of habit, if I plan a render in 4K I keep the resolution of the TL in 4K and as I have an external monitor in HD, I set the output scalling in HD.
In the delivery, you then choose the resolution of your render.

You can also do the opposite test: with a 4K clip, you choose a TL in HD, you put a Lens Flare with tracking (or other effect) and then you change the resolution of the TL in 4K: you must not have offset in the render.

This is the independent resolution (timeline resolution).

(do a search on the site: there are several trends: some do like me, others differently)
