The weather is finally good enough for me to shoot with blue sky. This time I have a variable ND filter on so I can use the LX100 to shoot properly at 1/60, F5.6 (for maximize sharpness), and ISO200 (the lowest it would go). The variable ND filter I use is "Fotga", so it's not $300 kind of variable filter, but general consumer feedback on the variable ND filter is good so don't blame it on any artifact.
1.) Here is the first upload, the clip is right out of the camera, uploaded to Youtube. File size is 556Mb
2.) Here is the 2nd upload. The clip was brought in to Adobe Premiere CC, sequence setting is "Red Epic", during publish, the bit rate is set to target 80Mbps, and render is VBR 2 pass. File size is 453mb.
3.) This is the last upload. I took the 80Mbps clip output from Premiere CC and ran through Handbrake for Web Optimization. I will release the Handbrake setting info if people are interested. File size is 116Mb.
The reason of the test is to see which one Youtube reprocess and further compress the most. The wish is the 80Mbps version will be used for archive, and portfolio play back locally, so the bit rate is reasonably high at 80Mbps.
The Handbrake version is to hope that once the file is web optimized, Youtube would leave it alone and stream it as it is.
See which one you think is good and no artifact or blotch on the sky, which when come to underwater, the blue water is where we judge if the video is noisy or not.
Let me know if people are interested to download the original clip straight out of camera.
Last note, this is for 4K testing, so make sure to turn it on.
