seeking 4096x2160 2.40:1 aspect ratio mask files

wwjd wrote on 7/20/2014, 9:05 AM

can't find them anywhere. got 3840 no problem. can anyone make me one? I like that skill
PS I googled it for quite the while, but maybe someone else can find one?

or even 2.35:1 for 4096 - not the 3840 UHD size

Is this what you're looking for?

... or Cinemascope 2.39:1 (4096x1716)

Of course, it's also trivially easy to type these numbers into the height & width of Pan/Crop and not need any mask file at all.

thanks! I'll give those a try!

but how do you do that on the MASTER video track? I mean without gumping up all the lower video tracks? When I do that, my lower tracks resize to fit and I get black bars at left and right :(

"When I do that, my lower tracks resize to fit and I get black bars at left and right :( "

Pan/Crop on the video event.

Un-check "Lock Aspect Ratio".

Type in new Height

You will have to ensure there is black generated media on the bottom track. either at 0,0,0 if you will be applying a Computer to Studio RGB filter, or 16,16,16 if all your assets are at studio levels already.

Cool.
I prefer a mask rather than fixing crop per clip. If only there was a Pan/Crop on the main video output.

I think I got it figured out: use a BLACK SOLID COLOR, cookie cutter it to open the ratio, and that works, but I think it is a CPU hog

Thanks Chienworks. would be perfect with out the "Gray" edge. Did you find or make those?

Chienworks wrote on 7/20/2014, 6:54 PM

Made. Hmmm. There shouldn't be a grey edge. I'll check them.

I don't believe the cookie cutter would use any more CPU then a still image. Perhaps less, there's no external libraries to load & drive to read.

seemed like cookie cutter stutters playback more than an overlay. nothing scientific, just SEEMS like it :)

Pan/Crop should use the least CPU overhead of any method.

It should be easy to always get the proper ratio applied to any clip. If the clip is smaller than 4096 wide, then simply enter the clip's actual width, then divide this by 2.4 (or 2.35) and enter that as the height. You should get a perfect result every time.
