Canon R6 video specs (limits, file splitting, and card workflow)
This page is based on Canon’s EOS R6 manual section for Movie Recording Size. It focuses on the workflow constraints that affect real recording: card prep, file splitting over 4GB, and recording time limits.

Cards that can record movies (Canon reliability advice)
- Format cards in-camera before recording for best performance.
- Use high-performance cards with writing speed sufficiently higher than the bit rate.
- Before recording 4K: Canon advises formatting cards using [Low level format].
Manual: Cards That Can Record Movies
Movie files exceeding 4GB
If a Canon R6 recording goes past 4GB, that does not automatically mean anything went wrong.
- SDHC (FAT32): files split at 4GB into multiple movie files.
- SDXC (exFAT): movies can be saved as a single file even if they exceed 4GB.
That is normal file-handling behavior. For editing, you should generally treat those files as parts of the same recording workflow rather than separate unrelated clips.

Recording time limits (Canon)
- Non-High Frame Rate: maximum 29 min 59 sec per movie

Recording limit in real use
Direct answer: the Canon R6 has a 29 min 59 sec maximum per movie for non-High Frame Rate recording.
That is the formal clip limit, but in real use the R6 can also be constrained by heat, battery, card performance, and how quickly you can restart a clip during live work.
- Normal movies: up to 29 min 59 sec per clip
- Practical takeaway: for interviews, ceremonies, or anything you cannot repeat, treat the R6 as a camera you need to manage actively rather than a body you can leave rolling unattended.
