Well *if* you're talking 368 frames, then 368 x 42 seconds* = how much longer it would take doing it at 1080 p
So that's over 4 hours longer (15,456 seconds = 257.6 minutes = 4.29 hours) ... yes?

(* in this particular case, It takes 42 seconds longer per frame to render 1080p than at 720p)

So ● 4hrs extra for 'actual' 1080p vs
      ●15mins extra for gigapixel upscale to 1080p

(hope I've done the maths correctly).

Please be patient with me ..... I don't always 'get it' the first time 'round - not even the 2nd time!   - yikes! ... 

● MSI GT72VR Laptop, i7 7700HQ 4-Core 3.8 GHz 16GB RAM; Nvidia 1070, 8GB Vram ● iClone-7.93 ● 3DXChange Pipeline 7.81 ● CC-3 Pipeline 3.44 ● Live Face ● HeadShot ● Brekel Pro-Body ● Popcorn FX ● iRAY ● Kinect V2 ● DaVinci Resolve17 ● Mixcraft 8.1

So what I noticed was the large size of the PNG output files. I checked the properties and apparently it's 48-bit PNG (16-bit per color). I didn't know that existed...  

EDIT: Apparently, this has been around for quite some time...

So I downloaded the videos shown here by 4u2ges (both the 1080p AND his original 720p)
Then, using a 1080p project in Vegas, used the 1080p (gigapixel upscale) as the background video, and simply cut a window in the center for the 720p original. (which was enlarged to fit).
Now of course Youtube has done it's 're-encoding' thing, but since both have undergone equal degradation, I guess it 'sort of' gives a reasonably fair comparison.
Anyway - here it is ... (and a big thanks to 4u2ges for the test footage).

Cool test Sonic7! Thanks for taking time and making this simple enlarge vs gigapixel upscale comparison presentation.

No problems, I'm like Mark (IllusionLab),  - I love these sort of 'tests'.
But hey, if wasn't for your footage - it wouldn't have been possible.
Also, a big thanks to Jarretttow for this thread! .... 

(I must say, I'm rather impressed by the gigapixel render).

+1 I bought the software after reading his original post

Thanks guys for furthering the tests.  Unfortunately, it doesn't illustrate the true difference that Giga is making... that is, an up-rez of a 1280 YouTube video is significantly different than an up-rez of the original render.  My primary reason for being skeptical is there are no videos on YouTube showing what I suggested an A/B of up-rezzed 1280 with no sharpening and Giga sharpening... if this product was as revolutionary as it claims it would be an industry standard and every studio that needs to deliver 4K content would have integrated it into their pipeline.  Also, as the subject matter - like hair, or particles or smoke would most likely introduce serious artifacts as the software may be "smart" per image but is blind to the fact that it needs to be "next frame" aware for video sequences.  The "old school" unsharp masking technique can run in real time in DaVinci Resolve Studio and is used on every film or TV show you've seen - because it adds sharpening which is "dumb as soup" and does not care if there is hair, or particles or smoke in the footage.  My advice, if there's a demo try it... and make sure you give it some challenges.  The results I've seen have an unnatural 'smoothing' in non sharpened areas (which are primarily edges)... so subtle skin textures, hair, repeating patterns - bricks, or plaid clothes for example would be a better indicator than shiny plastic robots (no offense 4u2ges... it's just hard edged flat coloured objects make processing artifacts harder to detect).

I've already downloaded the 30 day trial, but not sure how much testing I'll get through today. I do find it interesting since it's all a learing curve even if it turns out to be not the answer for me personally. But, at the end of the day I guess we all have to make our personal choice as to how we proceed along the many and varied pathways on offer ....

Non taken Mark. But remember, I mentioned it would most likely fail to produce acceptable visual output with fine texture.
But nonetheless I did acquire it as it does produce excellent visuals for specific scenes.
I will continue testing it and next time around I'd post something that is less acceptable.

True, this is only one method of skinning the cat -- the cat being iray render speed.
We have four options:
1) render smaller
2) add more GPU's
3) optimize the scene/textures/iray settings
4) change frame rates
Of course, the results are not perfect, but they are acceptable most of the time. I would probably still render tight facial shots at full rez.
I'm about to start a new thread about option 4 above...I think that is very promising.
I'm glad it helped some of you out, and don't forget, you can upscale your textures with gigapixel too...the results are pretty nice!
