The document discusses file-based video compression formats, recording media, and archive media. It covers common video codecs like MPEG-2, H.264, ProRes, and XAVC. It also discusses color sampling ratios and calculating file sizes. For recording media, it describes the transition from tape to digital file-based workflows using SD cards, solid state drives, and hard disks. Common archive media discussed include LTO tape and optical disk archives.

4. File-Based Video Compression
Codec or Wrapper?

5. What is Wrapper?
Wrapper are simply a container that hold
together your audio and video file as one file.
.MXF
.AVI
.MP4
.MOV

6. MXF – Wrapper

7. QuickTime – Wrapper

8. What is Codec?
Codec are the way that the camera.
Compresses the information from Sensor.
Send it dictates exactly how the image is stored.
And recorded. So it directly impacts things like
quality compression artifacts noise.
How easily editing software can handle it

9. INTRAFRAME vs INTERFRAME

31. How to?
CALCULATE FILE SIZE

32. How to calculate?
Video bits rate Ex: Prores 422 120 Mb/s
Duration : 2hrs.
File size: ?
1. Change bit to Byte
• 8 bits = 1 Byte
• 120 Mb/s = 120/8 MB/s
• =15MB/s
2. Duration : 2 hrs.
• = 15MB x60 x60
• =54,000MB /hr
• =108,000 MB
3. Change MB to GB
• 1024 MB = 1GB
• 108,000 MB = 108,000 /1024 GB
• = 105.46 GB

33. How many minute to copy or transfer?
File size :105.4 GB
Transfer rate : 1 Gb/s
1. Change GB to G bit
• 1 GB = 8 G bits
• 105.4 GB= 105.4x8 Gb
• =843 Gb
2. Transfer rate 1 Gb/s
• = 843 /1
• = 843 Secs
• = 14 Minutes

34. Calculate Tools
