The Sony Alpha 7R II has a maximum video recording time of 29 minutes, but only for some formats. That limit is also dependent upon multiple factors like camera settings, media storage size, camera power, and internal camera temperature. See details and notes below for more information.
Maximum continuous video recording times for the Sony Alpha 7R II

All Formats & Frame Rates (except MP4)
It requires a lot of power to perform high quality movie recording or continuous shooting using the image sensor. Therefore, if you continue to shoot, the temperature inside the camera will rise, especially that of the image sensor. In such cases, the camera turns off automatically since higher temperatures affect the quality of the images or affect the internal mechanism of the camera.
The duration of time available for movie recording varies with the temperature or condition of the camera before you start recording. If you frequently recompose or shoot images after the power is turned on, the temperature inside the camera will rise and the recording time available will be shorter.
Using SDHC cards: The card will be formatted in FAT32. If the file size exceeds 4GB, recording will continue and a new file will be created automatically.
Using SDXC cards: The card will be formatted in exFAT. Even if the file size exceeds 4GB during recording, the movie will be saved as a single file.
If the file size exceeds 2GB while recording in AVCHD mode, recording will continue and a new file will be created automatically.
Movies cannot be recorded simultaneously in both memory card slots when using a combination of the exFAT file system and FAT32 file system.
Video is recorded in a variable bitrate, which automatically adjusts image quality depending on the shooting scene. Therefore, recording times will vary depending on the content you are shooting and the shooting conditions.
