When up scaling footage, eg: 1080p to 1440p. Would the footage need a little sharpening? cause effectively your stretching the footage so it would make sense right?
In relation to this as i do sharpen my 1080p footage any way would upscaling footage need more sharpening?
EG: 1080p > normal sharpen
1440p up scaling > more sharpening because its stretching 1080p
Im very new to video production so any help would be appreciated - cheers :)
Vegas also has dedicated FX for this - smart upscale, which also sharpen I think. But maybe it checks out better? (you need to use smart upscale as first FX in event, even before pan&crop)
I upscale when i render but what im trying to achieve is "knowing if i need more sharpen" when i upscale, and when i upscale "if it needs more sharpening" than native
I see what you mean though, theres a noise slider on the fx of Smart upscale, is this more effective than upscale rendering? @Radomir
FHD comes in two varieties -- 1920x1080, and 1440x1080 anamorphic.
Both are 1080p. Are you sure you're not conflating the two?
Or are you shooting for 2K 2560x1440 ? If so, there are no practical reasons for doing so. Upsampling is best handled by your hardware.
Please explain your purpose. Include complete file properties for both source and output. Thst said, sharpening is a poor substitute for sticking to best practices.
Im upscaling 1920x1080 to 2560x1440
Im wondering if you would need to sharpen the footage as you are stretching the image?
My purpose for this upscale is to correct Youtubes VP09 codec which can only be achieved by having 1080p+ resolution
My source is recording at my base canvas of 1920x1080 and in Sony vegas and my render output resolution is at 1440p (see in photo), no Smart fx used to upscale, just set at render settings to upscale

I would not upscale.
The slight advantage in YT VP9 bitrate is overshadowed by the degradation of quality from software upscaling, with or without sharpening. Others here, even moderators, may disagree with me. My subjective experience (meh) dissuades me from running SSIM/PSNR tests, this time. And I haven't seen any from the internet alchemists, either. Where YouTube is concerned, the tail does not wag the dog. That's an opinion.
concerning my other question, would you say that you should sharpen when upscaling?, i feel as though when i do upscale it looks a bit....not blurry but not sharp either. Like if i rendered at 1080 its clear as day but when upscaling it looks...."not blury but not as sharp as 1080p native" dang im trying my best to describe
Also thanks for t he advice @Musicvid
Ill take that into consideration
No. High pass sharpening is in itself destructive. Low-block filters, aka Unsharp mask, NLMeans noise reduction, kernel matrix, and median, are all I routinely use, unless as an effect. They are characteristically very slow.
That said, Sharpen=0, first in fx chain, is not terribly destructive, but adds a little piping around the edges, at least in VP14.You might try that. Lanczos isn't bad either. Smart sharpen is not available to me. I like playing odd man out, gets me a lot of attention.
I just tried "Unsharp mask" with the light preset and dang it looks awesome, changes the color a bit though
would you put unshrp mask before color correct and brightness and contrast?, i put levels on output
Yes, always first. I love unsharp mask. Yes, Levels always go last. Great intuition!
Here is a worst-case example of the problems with regular sharpen. Can you tell I'm picky?
-----------Original--------------------No blowouts----------------Heavy Sharpen (bad)----------Blown pixels (unrecoverable)
changes the color a bit though
Probably only in the shadows?
Hey everything i learned in Video is from you so of course its great intuition 😊. I just need to learn a few more things cheers for the help @Musicvid do you have a paypal or any other way i can thank you?, maybe a youtube channel?, youve really helped me alot
I sent you a PM. And you will become a great asset to this forum, not because of anything with me, because I get it wrong a lot, but because you think for yourself and dare to make mistakes, which are the true best teachers.
Mmm, enjoying that 'nog as we speak. Thank you, this a first for me!
No prob man, i take care of the people i appreciate
And I appreciate the people who take care of me.😉
