title: How to store very large 3 dimensional matrix in HDF5 format?
body: <p>I have a very large matrix which is a video file as an array of frames, each around 350x250 resolution. I have around 8,000-10,000 such frames in a single video file, which is around 1-1.5GB in size. 
  I have figured that HDF5 is a good file format for my use as I have to perform a lot of mathematical operations on the file (across the entire depth column). 
  My problem is that I am unable to store this 3D matrix in HDF5. Can someone suggest me how to store these frames in an incremental fashion (adding frame by frame to the hdf5 file) as a 3D matrix in hdf5 format? 
  I am using h5py python package.</p>
