Try fwrite(). Just write the bytes stream to a file. fwrite does not care what the bytes represent.

I knew this Question was coming as soon as I read your Question about how to convert a video to a bit stream. My answer at that time was
vidcontent = fileread('YourVideoFile.avi');
bitstream = reshape(dec2bin(vidcontent,8).', [], 1) - '0';
The reverse of that is
bytestream = uint8(bin2dec(reshape(char(bitstream + '0'), 8, [])));
and now you can use fopen / fwrite / fclose to write the stream to a file.
Note that this is the general process to transfer any file as a stream of bits. And usually when people ask specifically about transferring video what they really want is a video streaming mechanism, especially one for wireless or radio that is robust to data corruption and can survive dropped data, to play the video on a device rather than to store the data. What we have shown here is not a video streaming mechanism, it is a "convert bytes to bits" mechanism.
