What’s Important in a Recording Format? (Camera Lesson 10)
Summary: Ryan covers the key specs you should pay attention to when considering a recording format: codec, color sampling, bit rate, and bit depth.

With all of the recording formats and external recorders out there, how do you know which one is the best fit? In this video I’ll cover the technical info you should be aware of so that you can choose the best format for your specific project.
So let’s start by taking a look at the anatomy of a video file. The first part of a video file is its container type. There are a ton of container types out there, and the easiest way to see what the container type is is to look at the extension, which is the last three letters of the file. Some extensions that you might run across are MOV, AVI, MP4, and MXF, among many others. Unfortunately you can’t tell a lot about a video file based solely on the container. That is because the container is only a wrapper that houses all of the video information for that file. The information within that file can be arranged in any number of ways. So let’s take a look at those individual parts.
The term codec is short for compressor/decompressor. It defines how the video data is compressed to the media card and then later read, or decompressed, by the computer system to play the video. So the codec defines the way that information is stored within the container. Some examples of codecs are H264, ProRes, Raw, JPEG, and M-PEG4.…
