Patch limitations

Playback
To minimize the possibility of interrupted recording, use a Class 10 memory card. Preferably UHS-1.
 * 64Mbps hack: no playback in camera
 * 54Mbps hack: no playback in camera
 * 36Mbps hack: playback works in most cases.

Removal of Time limit
If you remove the time limit for video, there is still a file size limitation. This is not a file system limitation, even though the result (max 4GB video size) is the same as what would be the problem if it was the file system. The movie recording code only uses a int32 (4GB size number) to track file offsets, the file system uses int64 (4GB x 4GB) so it's really the movie code. While this is/was the problem for earlier models, the movie recording code is not yet 100% found for the D5200 models, thus why the record limit has also not be hacked yet.

If you need to record longer videos, you will have to use the removal of time limit-hack and lower bitrate.

Liveview

 * Screen goes black if the exposure time is longer than 1/40s (D5100)
 * Autofocus fails if the exposure time is longer than 1/40s (D5100)
