What it does

How heavy a video, a set of photos or a sound will be, and how much a card or a drive holds. Pick Video, Photo or Sound at the top.

Video: ProRes from Apple’s published data rates (1080p at 29.97 fps), scaled to the resolution and the frame rate: close to Apple’s figures, within about 1 %. DNxHR from the ranges Avid publishes (≈). For H.264, H.265, Blackmagic RAW or any other codec, type the bit rate your camera shows, in Mb/s or MB/s (1 MB/s = 8 Mb/s). PCM sound can be added.
The container (.mov, .mp4, .mxf) barely changes the size (less than 1 %): what counts is the codec and its bit rate.
Photo: uncompressed RAW and TIFF are exact. Lossless RAW, JPEG and HEIF depend on the image (detail, noise): marked ≈, orders of magnitude.
Sound: WAV / AIFF = sample rate × bit depth × channels; MP3 / AAC = the bit rate. Exact.

Sizes in decimal units (1 GB = 10⁹ bytes), like card makers and macOS; one line gives what Windows shows (GiB). Tap a value to copy it.
