Before using Chroma Key

Chroma Key is a choice for those who want to remove video background and replace it. But before starting recording remember these tips :

Make sure the backround is lighted and not dark.
Make sure to avoid wrinkles
Everything same to the color of background will be removed so dont use green or blue clothes.

Lets see what happens when the background is not lighted enought.

Using Ultra Key in premiere causes shadows and if you remove those shadows the subject becames less accurate, I mean you cant see more details on the edges and you see like something is moving on the hairs.

The exact same thing is when the background has wrinkles and those dark areas are very hard to remove, even if in After Effects.

"But you can avoid these problems if you care a little bit by working with the background before the shoot"

Video format explained and compared

This article explains main video formats and later compares with photos the quality. Audio Video Interleave (.avi) Developed by Microsoft and released with Windows 3.1 way back when false teeth were still made out of wood, AVI files have been a work horse of digital video. Although its popularity has been waning, lots of legacy video in AVI can be found all over the web. More recently, AVI has been abandoned for Microsoft's WMV (Windows Media Video). One of the most maddening things about AVI today is that the format doesn't allow for specifying an aspect ratio, so a 16:9 AVI video may start displaying at 4:3 - this is less of a problem if your player allows you to manually select aspect ratios. If you're watching in the non-pro version of QuickTime though, you'll have to learn to live with people being unusually narrow. Advanced Systems Format (.asf) ASF is a proprietary Microsoft container that usually houses files compressed with Microsoft's ...

1100 $ AMD system to edit 4K

Amd recently has released some great CPU with high cores and low prices. About 305$ you can get an editing beast with 8 cores @3.7 GHz. This cpu will be enough to edit smoothly. There are more expensive cpu and higher cores or higher frequencies but to be honest we don't need real time exporting. You can have a break and drink a coffee while exporting your video. Memory is important. Lower the size the more time it takes to do task. I recommend 16GB DDR4. (2400Mhz or more is great also). That amount will make switching between applications easier and faster. So right now we spent 305 dollars for cpu and 150 for memory (RAM). Sum is 455 $. Lets suppose you are upgrading your system so you have some hard drives and some ssd maybe. I love SSDs for system and as a drive for footages. For the system Samsung EVO 970 will do a great job for 90$ ( Sata m.2 250GB @Read speed up to 3400 MB/s). Asus x470 Pro is a great mainboard for 160$. Also find power supply more than 500w. I recommen...
