1080P Quality in 1440P

PostWed May 12, 2021 11:05 pm

I am unable to get 1440P quality out of my renders from 1080P source videos.

This is extremely upsetting. It seems I am unable to use good video editing software. I got here because my cheap software was malfunctioning.

Now I can't use DaVinci, Premiere looks horrible, Videopad fails to render.... it's f'ing ridiculous.

Here is the 1080P version:

Here is the 1440P version:

New 1440P.jpg
New 1440P.jpg (499.87 KiB) Viewed 3549 times


I have ensured both unlimited bitrate and auto, all to 1080P quality in 1440P. I have tried a higher bitrate through 4K export only to have the images all identical.

This is very unfair. It seems I cannot do ANYTHING anymore. There is literally no reason for this.

Please help. Thank you.

Both images look the same. You really need to provide more info about what your issue is.

Thomas, before rendering are you changing your timeline resolution in the Master Project settings to UHD? You can then add a Custom output setting of 1440 in the Deliver page.
Also, what were you hoping rendering at the higher resolution would do? It wont increase the quality of what was already in the 1080 video, it is merely upscaling it which will make it compatible with UHD displays and help alleviate re-encoding artifacts on YouTube. You can't add something that isn't there in the first place by upscaling.

In Videopad when I would render 1080P in 1440P it would come out looking better than the original on this 1440P monitor.

Resolve does not work the way it should. 60 FPS videos shot with a camcorder come out identical quality as source in 1080P to 1440P while my old Iphone's 30 FPS footage comes out much worse than the source.

Premiere looks horrible, Resolve looks horrible and now even Videopad is useless as it seems it will not render ANYTHING now!

I take video editing seriously. I am a home user, nothing professional and yet I am willing to spend $300 on an editor. I guess I can't have it.

I am a home user too. All my videos are shot at 1080 50fps. I upscale them all to UHD for YouTube. Resolve is working exactly as it should. Your expectation that rendering 1080 at 1440 or higher will magically improve the baked in quality of the original footage is misplaced.

Sorry for coming across as snobbish. I'm just really upset right now.

I could have sworn that rendering at a higher resolution than the original looked better than the original on a monitor that could support it. I guess it's just me.

Thanks for the help.

OK I did some testing with old software and see now that rendering in a higher resolution than source will produce no difference (if lucky).

What I cannot understand here is why you would render at 4K from 1080P when the 4K version and 1080P versions look no different on a 4K monitor.

I have 720P rendered at 1080P on a 1440P monitor. There is no difference from 720P. Why would anyone encode at 4K when it does nothing but increase file size? It does not help people in 4K who should just run in 1080P anyway.

Sorry again for sounding like an ass. It was a heat of the moment thing.

Why render 1080 as uhd ? because when you opload to YouTube your files will be convert to VP9 = better quality on YouTube !

And that's the only reason.
If you watch it on a good 4K TV, it's taking care of upscaling anyway.
If you go from HD to UHD you'll need for times the data rate or it'll look worse!
