Canon R100 video specs (limits, file splitting, and card workflow)
This page is based on Canon’s EOS R100 manual section for Movie Recording Size. It focuses on the practical 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 R100 movie file goes past 4GB, the camera may split the recording into multiple files instead of failing outright.
- 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. In practical use, the clips should still import and edit as parts of the same recording session.

Recording time limits (Canon)
- Non-High Frame Rate: maximum 1 hour per movie

Recording limit in real use
Direct answer: the Canon R100 has a maximum 1 hour per movie for normal movies.
In practice, that means the R100 is more predictable than the old 29:59 style cameras, but you still should not assume you can ignore battery life, card performance, or clip restarts on longer shoots.
- Normal movies: up to 1 hour per clip
- Practical takeaway: if you are recording classes, interviews, or longer talking-head sessions, set a timer and be ready to roll into a new clip cleanly.
