Create a config file (~/rr_config.yml) like this
user: username
ip: remote_host_ip
rmt_tmp_dir: /tmp/RRender
debug: false
Then execute command as
remote_render -r success_list.output -e failed_list.output -c ~/rr_config.yml -d $(pwd) -s 5
This command will speed up videos in current dir to 5X.
To change bitrate, use -b instead of -s.
