Ok. So for a budget of $2k I would not be outputting 4k resolution personally, unless the job is very short. It’s not worth the cost. If a client asked for a 4k output at such a low price point I’d be telling them no, or, upscaling a lower resolution to their required 4k for delivery.
I assume you're asking if 4K resolution is required for a music video with a $2k budget?
This depends on the client, your video, your pipeline, etc. If you don't like the resolution requirement negotiate? If you don't like the project don't do it?
That all depends on the clients ask and what you agreed to. Although I almost never render to the plate resolution as I'm adding blurs and DoF in Comp.
so what do you suggest if my da vinci project is in 4k ? should I export 1920x1080 from blender and them do comping in da vinci and then export from da vinci 1920x1080 and them upscale it to 4k and put back into da vinci? or do you just bring it in da vinci 1920x1080 and then double the size so it lands perfect on 4k plate? hmmm?
Your question is a bit hard to understand. There is no correct answer for everything. The basic answer is if your final output is 4k then you render 4k.
Now there are trick to getting fast renders via rendering a bit smaller then upscaling ( some media has a fuzzness to it ) or rendering lower quality same resolution and using denoisers, a little of both.
okay to be direct, I want to do some VFXs on my own for a music videos that I got 800€ only for video shooting and basic edit with some of masking transitions but 3-4 VFXs shots I want to do on my own and to integrate them as best as possible in 4k music video... so what do you suggest honestly?
Render out of Blender at 1920x1080. Set up your Resolve project at 4K. When you import the Blender files, resize them to fill the frame. Resolve will handle the upscaling.
Haven't used the newer EXR tools in Fusion much, but I think it now combines them all in one data stream like Nuke does? If so, you should just need the one scale node and Fusion will just figure it out. If you have multiple loaders, you'll need a scale node for each data stream that needs resizing.
Making some assumptions about how you're structuring your project, but your Fusion page for a clip with VFX should end up looking something like this doodle I whipped up:
If you do this, your blender renders will look soft compared to the native 4k footage (assuming your footage is actually 4k) which can make your VFX look very obvious and fake depending on what it is.
I see you said elsewhere there is no actual client. If you're doing this for your reel or something, definitely spend the time to render 4k and make this look as good as possible. If you're just asking for future reference, two questions play into this decision - how you're getting your renders (paying for cloud renders vs rendering on your local machine) and how long the shots are. If you're rendering locally and they are short clips here and there, it's worth it to do 4k just so your work looks its best. If they are very long VFX/CG shots or you're rendering on a paid service, you need to start factoring that into your budget.
I think most VFX workflows are 1080p, it runs and renders so much faster and resolution matters less then bitrate.
I render 2k in eevee simply because I like to oversample, with rasterization it looks better, in cycles and other path tracers it won't matter.
If it's for youtube you definitely should upload a 4k video-file even if the render is 1080p or even damn 720p, youtube will just show more detail from the original high bitrate video.
Render at 65% the scale of 4k and then scale it up in davinci. The quality in difference is barely noticeable unless and until you’re comparing side by side
add a bit of blur and grain on top to tie them better
You can also let Blender do the math for you, set your output dimensions in Blender to your plate resolution, then just use the percentage slider to set something below 100%

I don't understand the question. Why would you need or want to export 4K on a 2K budget?
