Once you tap the AWB button (blue) it turns red to fix the white balance.Im going to use FiLMiC Pro to show you how you can achieve great looking video with your smartphone and a low-cost camera app.
This can also be referred to as grey balance, neutral balance or colour balance. As you can see from the common word in all these terms, its all about balance. Therefore, it will help us as filmmakers and video producers to think a bit differently when it comes to colour. RGB is an additive colour model in which red, green and blue light are combined to reproduce a range of colours. We use the RGB colour model for sensing, representing and displaying images in electronic systems, such as televisions and computers. Take a digital image, any image are the parts that are supposed to be white actually white If they are, then most likely the other colours are correct too. Meanwhile, 100 red, 0 green and 0 blue obviously red. And so on. Because if we get the balance correct for white, everything else should be accurate too. Part of that compression process such as in h.264 and h.265 files can involve discarding colour information. Video Camera White Balance Mp4 And ManyThis is used in h.264, h.265,.jpg,.mp3 (audio),.mp4 and many other files. With digital images, the clever people discovered humans are less sensitive to missing colour than than they are to missing luma information (brightness and darkness). But, to put things simply, smartphones (and other consumers DSLRs and mirrorless cameras) record compressed video to save disc space and bandwidth. Video Camera White Balance Professional Cameras RecordOn the other hand, more professional cameras record video uncompressed, but then compress the video at the end of the filmmaking process. And streaming an uncompressed video file over your average broadband connection just wouldnt be practical. What happens is, while each pixel records and retains the luma information, 1 pixel of colour information is spread out over 4 pixels. Therefore, when it comes to colour, your h.264 file in fact only has 14 of the videos resolution. This is one reason why you might want to record video at 4K and then master at 1080p. ![]() ![]() For this reason, fixing incorrect white balance in compressed video can be less effective. And so it becomes more important to get white balance correct when youre filming. White balance is constantly adjusting and one number has to keep up with the other.
