Let’s talk about —specifically Apple ProRes —and why it remains the industry standard for editors who value their sanity.

If your camera only shoots in highly compressed formats (like a standard mirrorless camera capturing 8-bit H.264), transcode your footage to ProRes 422 before editing. While this won't magically add color information that wasn't captured, it will instantly free up processing power and eliminate timeline lag.
Yes, .prores files take up more hard drive space. But in the age of cheap SSDs, storage is cheap. Time is expensive. .prores
ProRes uses a variable bitrate encoding architecture. While Apple defines target bitrates for each variation of the codec based on frame rate and resolution, ProRes automatically scales the data rate depending on the complexity of the image frame. A static frame of a blank wall will require significantly fewer bits than a complex, high-motion frame of a forest during a rainstorm. This ensures that data is never wasted on simple images, while asset integrity is rigidly maintained during visually complex scenes. 2. Parsing the ProRes Family: The Six Codec Flavors

Approximately 45 Mbps for 1080p at 29.97 fps Let’s talk about —specifically Apple ProRes —and why
Traditional ProRes codecs require the camera to debayer (demosaic) the raw sensor information and convert it into a standard Y'CbCr or RGB video signal before compression. This locks in choices like white balance, ISO exposure mapping, and color space characteristics.

Conversely, ProRes utilizes compression. Every single frame of a ProRes video file is compressed independently as an individual image. There are no temporal dependencies between frames. Because the computer does not have to look forward or backward in time to decode a specific frame, decoding requires minimal processing power. This architectural difference is the primary reason a computer can seamlessly play back multiple streams of 4K or 8K ProRes footage simultaneously, while stuttering on a single stream of highly compressed 4K H.265 footage.

Ensure your external media drives or Network Attached Storage (NAS) units utilize fast connection interfaces, such as Thunderbolt 3/4 or 10GbGbE networking, to prevent data transfer bottlenecks during multi-camera editing sessions.
Most cameras shoot in H.264 or H.265 (MP4/MOV). Why? Because it’s efficient. It squishes massive video data into tiny files. Great for hard drives, terrible for editing computers.
