Footage Organization and Management Flashcards

What is the key distinction between a video 'codec' and a 'container format'?

Answer: A codec handles compression and decompression of data while a container wraps audio, video, and metadata streams together

A codec (like H.264 or ProRes) defines how video data is compressed and decompressed, while a container (like .MP4 or .MOV) is the file wrapper that holds audio, video, and metadata streams together.

What does 'transcoding' mean in a post-production media management workflow?

Answer: Converting video from one codec or format to another more edit-friendly format

Transcoding converts video from one codec or format to another, commonly used to create edit-friendly intermediate versions of camera-native files that are too demanding to process in real time.

Which storage solution is most appropriate for editing high-resolution video that requires sustained high read/write throughput?

Answer: NVMe SSD or RAID array providing fast sustained transfer speeds

NVMe SSDs and RAID arrays provide the fast, sustained read/write speeds required for editing large video formats like 4K or RAW without dropped frames or playback stutter.

What category of codec is Apple ProRes, and what is it optimized for?

Answer: An intermediate/mezzanine codec optimized for editing performance and image quality

Apple ProRes is an intermediate (mezzanine) codec designed for high-quality editing with efficient decoding performance and manageable file sizes, rather than for delivery or streaming.

What is LTO tape primarily used for in professional video production facilities?

Answer: For long-term archival storage of completed projects and raw camera footage

LTO (Linear Tape-Open) is a magnetic tape format used for long-term archival of completed productions and raw media due to its high capacity, low cost per terabyte, and a rated lifespan of 30+ years.

What does the '3-2-1 backup rule' specify for protecting video production data?

Answer: Keep 3 copies on 2 different media types with 1 copy stored offsite

The 3-2-1 rule means keeping 3 copies of your data stored on 2 different media types, with at least 1 copy stored offsite, protecting against hardware failure, theft, and local disasters simultaneously.

Why is it generally inadvisable to use Long-GOP codecs like H.264 or AVCHD as the primary format for editing rather than an intermediate codec?

Answer: They require decoding multiple interdependent frames simultaneously, creating heavy CPU load during scrubbing

Long-GOP codecs store video as groups of frames where only key frames contain full picture data, meaning the CPU must decode entire groups of frames even to display a single frame, causing heavy load during editing.
