This is a list of the volume of the AMIA listserv month by month. The second column indicates the total number of messages sent within the month. The third column is the value of the second column divided by 30 which provides a rough approximate of the volume of that month's average daily postings.

shell script for converting DPX+wav input to specific outputs of DNxHD, lossless h264 at 4:2:2 YUV 10 bit, and a streamable h264
#!/bin/bash
# larsencoder.sh
# author: dave rice dave@dericed.com
# description: This is a very specific script intended to take a collection of DPX images and a WAV audio file as an input and then create multiple derivatives using ffmbc and libx264
# dependencies: The script expects to use ffmpeg version 1.1 or higher compiled with libx264 and libfaac. Configure libx264 with either --bit-depth=8 or --bit-depth=10 as you wish.
# testing: If you need to generate sample files for testing this script I recommend making them via:
# ffmpeg -f lavfi -i testsrc=s=1920x1080:d=10:r=ntsc-film -start_number 100000 dpx_package_path/images/%06d.dpx
# ffmpeg -f lavfi -i aevalsrc="sin(440*2*PI*t):cos(430*2*PI*t)::c=stereo:s=48000:d=10" -c pcm_s24le dpx_package_path/audio/1.wav
