Recording audio in sync with video is done by using Linux-compatible (since most USB devices do not require additional drivers they just need to be plugged in and are ready to go - so far we did not find any incompatible devices) USB audio devices. These are widely available and range from simple thumb sticks with two 3.5mm jacks to multi channel recording devices with phantom powered XLR jacks. Please note that the USB connector on the Elphel 353 cameras is USB 1.1 and therefore has a max. data throughput of 12 Mbit/s (~1.43 MB/s) and a maximum cable length of 3 metres (9.8 ft). If you think...

The viewfinder hardware is a computer or embedded device connected to the camera over Ethernet. Using a router or switch there can be multiple cameras and/or viewfinders in the network. A wireless router can be used to free the connection from the wire and allow wireless communications/video transmission between the camera and viewfinder. What devices can be used: any laptop any netbook any desktop PC as well of course embedded devices, PDAs, MIDs, Smartphones Requirements: Ethernet Interface (or wifi) Software that can receive and display an rtsp video stream (VLC, Mplayer, Gstreamer or...

movie2dng Commandline Program When shooting video footage in JP4-RAW mode the files need to be converted to a postprocessing friendly format: a DNG sequence. This software takes care of that. The resulting DNG files contain the EXIF fields of the original frames and are stored with 16 bits (linear colorspace) per channel. movie2dng Usage: movie2dng [options] (at least one of --jp4, --jpeg, --dng or --pgm) SOURCE [DEST] This program will convert the SOURCE JP4 movie to individual frames named DEST-NNNNNN.dng, where NNNNNN will be replaced by the frame number starting at 1. Note that there is...

Introduction The research presented here aims at establishing a digital cinema editing workflow made exclusively under Linux machines. The steps described below start at the point in which we already have a sequence, or many sequences, of digital negative (DNG) files. In the diagram, they correspond to the stages immediately after the third grey box. Everything described from there on has been tested and is documented here. Even though it is the aim of this documentation to gather information related to the whole process – which includes capturing and monitoring the recording, transferring...
