- DYNAMIC RANGE: you have 13 stops of dynamic range. Our ordinary cameras have like 8 stops. That means less crushed shadows and less blown out highlights. Thats probably one of the best features of the camera, and you can see the difference in dynamic range wether you are using a 360p monitor or a 4k tv.
- COLOR INFO: those ordynary cameras record color information in 4:2:0 format. That means 3/4 of the color information is going to the trash. That results in a video with artificial colors, almost fluorescent. The Blackmagic records at 4:2:2 (preserves half of color info) and 4:4:4 (preserves all color info). That means natural colors, and Hollywood like colors.
- CODEC: ordinary cameras record videos at AVCHD 2.0 28+Mbps. Thats is A LOT of compression. That kind of compression reduces the amount of detail in your videos, creates more artifacts etc. The Blackmagic records at ProRes 422, the same CODEC used by professionals. The compression is at 220Mbps, so you will have more details, less compressions etc.
- RESOLUTION: In 1080p territory, the Blackmagic Pocket has one of the best resolutions, but that aspect is the least important of those 4.
- COMPUTER TO DEAL WITH THE VIDEOS: its actually the opposite of what you are thinking. Videos that are more compressed are harder to work with. Since the compression of AVCHD is 10 times higher, is actually worse to work with, and its very slow. Yes, the files of the Blackmagic will be bigger, and that means you will need a good amount of RAM memory, but the computer processor will thank you, because it's easier for them to work with ProRes!
We had that discussion a few months ago, about processing power, and let me tell you. Im currently editing A LOT of 4K RAW, 2.5K RAW and 1080p ProRes videos from BlackMagic IN MY NOTEBOOK, and its handling ALL of those files EASILY, so dont worry about post processing.
Here you can see a screen grab from the BlackMagic Pocket video that im currently playing with (And yes! Thats a video, not an HDR picture!!):
And here is a draw I made for you with the main differences
In the left you have ALL 8-bit cameras, and in the right you have the BlackMagic.
1. The skyes in the 8-bit is artificial-blue and has no gradation, is just one big blue thing. In the Blackmagic it has gradations and it has a real-life blue color.
2. Due to the lack of dynamic range, the highlights are blown-out (white clouds) and your shadows are just a simple black mud. In the Blackmagic your highlights are preserved (detailed clouds) and you can see shadow information.
3. The colors in 4:2:0 space are really artificial.
4. Due to the lower compression, better codec and great sensor, the Blackmagic has more detail, as you can see in the pores I made in that dudes face
. Even if both are 1080p, the Blackmagic will look like a higher resolution video because of the amount of detail it preserves - so yes, you WILL be able to see the difference in your 1080p screen.
When you watch you videos made with 8-bit cameras you think: "Man, that video looks nice, but its not movie-like nice, what am I doing wrong?"
And the answer is: 8-bit cameras are NOT cinematic!!
The problem ends with the Blackmagic pocket, because its the first affordable digital camera that WILL GIVE you cinema like images!
