Video settings, in depth
What are the right video settings on the R7 — formats, Canon Log 3, and true slow motion?
Three 4K sizes, three jobs
Every normal movie is MP4 in IPB (Standard) or IPB (Light). 4K UHD Fine is the quality size, capped at 29.97p. 4K UHD reaches 59.94p for motion. 4K UHD Crop records 59.94p from a narrower area of the sensor — reach at the cost of width. ALL-I exists here only for time-lapse movies. At 4K in 10-bit, Canon’s card requirements ask for V60.
Log is one switch here
Canon Log → On (C.LOG3) records Canon Log 3 in 10-bit 4:2:2 — flat, wide, built to be graded. The manual states the full dynamic range (approx. 1600%) arrives at ISO 800 or higher; ISO 100–640 is expanded and narrower, so do not base log exposure down there. View Assist shows viewable color on screen while the file stays flat. Canon Log and Canon Log 2 are not on this body. Shipping ungraded? Leave log off.
Quarter speed, and silent
High Frame Rate recording reaches 119.88 fps in Full HD, written as a 29.97 fps file — playback is 1/4 speed with the slow motion already in it. Sound is not recorded in High Frame Rate movies, and one clip can run up to 1 hour 30 minutes. 119.88 fps is this body’s ceiling.
Plan breaks, not settings
A single normal movie can run up to 6 hours, and the body runs on the LP-E6NH battery family with USB power an option. Heat is managed by behavior — the manual’s temperature icons mean stop and let the camera cool — and there is no [Auto pwr off temp.] setting on this body to raise any limit. Long days are planned in spare batteries, shade and breaks.
Shoot the same 20-second scene three ways — 4K UHD Fine with Canon Log off, Log 3 with View Assist on at ISO 800, and a 119.88 fps High Frame Rate take — and compare what each decision asks of you.
