2010.RMLL.info recording

Prefix

Elphel participated to http://2010.rmll.info/ with support of our Swiss partner - Alsenet SA. We organized an Elphel workshop and participated in conferences recording.

Goals

The goal is:

• keep high quality 1920x1080p MJPEG sources for all conferences what will be post processed.
• encode in free software and open data formats like WebM/VP8/vorbis and Ogg/Theora/vorbis as well as proprietary codecs such as h264.
• do all that with exclusively FreeSoftware

Hardware

Cameras

conference recording kit

Two types of cameras kit were used.

•  one is based on NC353L-369 camera and was used with an external SATA HDD (with external power) and a T.BONE MICPLUG USB
• the other is based on NC353L camera, audio/video is not synced and recorded on the camera, but on a networked PC.

Lenses

We used mainly computar's H3Z4518CS-MPIR and fujinon's HF16SA-1

Hard drive

We used Plextor 2.5" external eSATA and USB hard drive. When use with camera it is connected with a SATA-eSATA cable and powered with an external power supply. You can also use the disc as USB only connecting it to your PC for video post-processing.

USB Audio

T.BONE MICPLUG USB is compatible with ALSA running on the camera and provide phantom power to the microphone from USB. It also have a mini-jack output and gain control.

Software

FreeSoftware
