I would like to record footage at high resolution for one hour without interruption. I have a DSLR camera that, with 1080 pixels of vertical resolution and 50 frames per second, stops recording at 10 minutes and I have to press the record button again. Another hand-held camera can record for an hour but breaks it into chunks that, when concatenated, skip a fraction of a second.
I understand that this time limitation is because DSLR cameras use the
for reading and writing files from disks, and
FAT32 has a limitation of 4 GB:
The maximum possible size for a file on a FAT32 volume is 4 GiB minus 1 byte or 4,294,967,295 (2^32 − 1) bytes. This limit is a consequence of the file length entry in the directory table
Does another filesystem allow recordings without interruption for longer than 4 GiB or 10 minutes? And did cameras adopt such a filesystem?
Update: @Michael Liebman's suggested this Quora link that mentions "file chaining". I could solve the problem if the split files from a camera could be seamlessly joined and produce the same output as if I had been recording continuously. Does a format or camera standard allow this seamless juxtaposition?
Second update: I understand from the comments and questions that the file size limitation serves for DSLR's to avoid the EU's 5.6% import duty on cam-corders. One Sony camcorder can record continuously in AVCHD format but chops the clip into multiple files with around half a second missed in between files. Can another filesystem or video format record for camcorders footage for one hour without interruption?
