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 movies: Canon says to use [Low level format].
Manual: Cards That Can Record Movies
Movie files exceeding 4GB
If a Canon R8 movie file exceeds 4GB, the camera may split the recording into multiple files depending on the card format.
- SDHC (FAT32): files are 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, not usually a sign that anything went wrong. For editing and import, you should generally treat those files as parts of the same recording workflow.

Recording time limits (Canon)
- Non-High Frame Rate: maximum 2 hours per movie
- High Frame Rate: 119.88/100 fps up to 30 minutes; 179.82/150 fps up to 20 minutes
Manual: Movie Recording Time Limit
Recording limit in real use
Direct answer: the Canon R8 allows up to 2 hours per movie for non-High Frame Rate recording. High Frame Rate modes are shorter, with 119.88/100 fps up to 30 minutes and 179.82/150 fps up to 20 minutes.
That means the practical limit is not just a simple timer. For longer recording sessions, you still need to account for heat, battery, card reliability, and the exact mode you are running.
- Normal movies: up to 2 hours per clip
- HFR 119.88/100 fps: up to 30 minutes per clip
- HFR 179.82/150 fps: up to 20 minutes per clip
- Practical takeaway: the R8 is much less boxed in than the old 29:59 generation, but long recording still needs a workflow plan.
