preferences for 1920 to 4k

I think I know the answer to this but want to check... If I have 4k footage and my project settings are 1920x1080 and I edit with these settings and I want to render the project in 4k, do I need to change the project settings to 4k before I render - or just choose the render settings to 4K even though the project settings are 1920?

I would change back the project settings from HD to UHD for rendering the footage to UHD.

Desktop: PC AMD 3960X, 24x3,8 Mhz * GTX 3080 Ti * Blackmagic Extreme 4K 12G * QNAP Max8 10 Gb Lan * Blackmagic Pocket 6K/6K Pro, EVA1, FS7

Laptop: ProArt Studiobook 16 OLED (ProArt Studiobook 16 OLED (i9 12900H with i-GPU Iris XE, 32 GB Ram. Geforce RTX 3070 TI 8GB) with internal HDR preview on the laptop monitor. Blackmagic Ultrastudio 4K mini

HDR monitor: ProArt Monitor PA32 UCG, Atomos Sumo

Definitely, when you render with Voukoder. I prefer to set my project settings always to the desired output.

Since you are not using the Upscale FX, I would match the Project to the UHD source. It should preview smoother that way, all else being equal.

IDK if having a different project now affects the "phantom" project settings in some of the newer render templates. Worth a test.

@Roger Bansemer "Change the project settings to 4k before i render".... Without question, this is the correct approach for many reasons.

Thanks everyone. Will change project settings from 1920 to 4k before I render.

Why not setting project settings directly to 4k when footage is 4k and desired output is 4k?

What @3POINT said. Why not set the project settings to 4K initially?

Which brings me to a side question. Would having the project setting set to 1080 when the files are 4K, does that improve performance editing on a 1080 timeline vs 4K?

While it might improve things like the processing of effects and some color space stuff, it would not improve performance of general decoding...and in fact, an additional stop of downsizing the image would add (a very small amount of) work for the engine.

Does just setting preview quality from full to half not also improve performance...?

Not as much as most people would expect.

Our implementation and settings for the preview window are really old and dated. We are looking into some possible refactoring of this display so that it simply "just works" without users needing to change settings to figure out a setting that best balances their need for performance or quality.

Some users reading this may not have read Nick's FAQ #22 recently.

Highly recommended study, noting that it was written in 2016, so it applies to legacy projects like Roger's.

There are special instructions for setting your project to use "Smart" filters and AI Scaling, which require additional reading of the Vegas Help topics.

Best tool for learning this stuff is running your own experiments, changing only one setting at a time, and changing it back to default before your next test.
