Proxima ✨Check out the Docs!✨https://in03.github.io/proxima/Proxima makes queuing proxies from DaVinci Resolve a breeze.Launch the worker on as many computers as you have free and it'll pool all the free CPU threads together to encode multiple proxies at once. Only have the one computer? Encoding runs entirely on the CPU, leaving GPU-heavy Resolve with plenty of resources to continue editing while you pump out proxies. Once they're finished, they're automatically linked.Why make proxies?DaVinci Resolve's greatly benefits from having all-intra media, like ProRes or DNxHD. If you shoot in h.264 or h.265 like many do, you're likely to see great performance improvements using proxies. This application makes queuing, encoding and linking them quick and easy.FeaturesResolve 18 + legacy Resolve 17 supportDistributed encoding on multiple machinesUtilizes all CPU threads for encodingQueue only used proxies straight from a DaVinci Resolve timelineAutomatically link proxies after encodingFlexible queuer/worker arrangement allows background encoding on same machineVersion constrain prevents incompatabilities between different machinesEasy YAML based user configurationAdvanced configuration validationAutomatically checks for updatesControl Celery with Celery commands from CLI, even when installed with pipxMulti progress-bar#190Faster config parsing and validation with TOML#258Manage configuration from CLI#258RoadmapBetter Apple silicon supportInteractive timeline selection#161Better resource-utilization with encode-chunkingMultiple, customizable proxy-presets with rule-based matching#201Easier cross-platform paths via path-mappingPre-flight checks - encoding settings validationUI improvementsMonitor Web AppWhat about Blackmagic's Proxy Generator?I started this for the company I work for, well before BPG was on the scene. If BPG works better for you, go for it! As it stands BPG won't do any all-intra codecs on Windows, which is a dealbreaker for us. It also works on a watch-folder basis with no filename whitelisting or path-filtering rules. That means EVERY video file becomes a proxy, whether you need it or not. Our workflow often sees the shooter doing a rough assembly of chosen takes as an exported timeline. We simply import this timeline and queue proxies from it. If you work with chronic-overshooters, you'll save a heap of disk space and encoding time queuing proxies from a roughly-organised timeline.Ooh, I want it!PrerequisitesOne or more editing computers with DaVinci Resolve Studio installed and scripting enabledAn always on computer to run the broker (e.g. server, NAS, primary-desktop, Raspberry Pi)Worker computers (decent resources, can overlap with editing computers)all above machines on LAN and able to access same files via same filepath.NoteOnly Davinci Resolve 18 is supportedPlease check out the "resolve-17" branch if you need Resolve 17 support.
Prior versions are untested, but may work depending on Resolve's API feature set for that version.InstallationProxima is composed of three major parts:the 'queuer' responsible for interfacing with DaVinci Resolve and sending tasks to the brokerthe 'broker' (Redis) that distributes jobs to the workersthe 'worker' one of potentially many workers responsible for doing the actual encodingCLIThe 'queuer' and 'worker' are bundled together in the CLI app. They are both installed from the same source, called from the same command and share the same configuration file. As such, any computer that has the CLI app installed can both queue proxies (so long as Resolve is set-up) and run workers. Install it with pipx:pipx install git+https://github.com/in03/proximaBrokerThe broker is best installed on an always-on computer or server. If it's not running neither queuers nor workers can communicate.
Very little configuration is required. Just make sure it's accessible over LAN. Redis and RabbitMQ are Celery's best supported broker backends.
Only Redis has been tested extensively with Proxima.Install Redis with docker:docker run -d --name some-redis -p 6379:6379 redis-server --append-only yesMonitorAn in-house web-app monitor for Proxima jobs is coming and will include some really helpful, specific features.
Until it's ready, if you want to monitor your jobs, it's a good idea to install Flower - an official monitor for Celery tasks and workers.
Install it with docker alongside your broker:docker run --name flower -e $CELERY_BROKER_URL=redis://192.168.1.171:6379/0 -e FLOWER_PURGE_OFFLINE_WORKERS=300 -d flowerSet the IP address and port to the same as your broker container. Don't forget the Redis protocolredis://.
Consider settingFLOWER_PURGE_OFFLINE_WORKERSif you don't have a well-defined set of computers to run the workers, or there's potential to change worker hostnames.300for example, would clear the list of offline workers every 5 minutes. This just keeps things tidy.How do I use it?Usage: proxima [OPTIONS] COMMAND [ARGS]...

Options:
  --install-completion  Install completion for the current shell.
  --show-completion     Show completion for the current shell, to copy it or
                        customize the installation.

  --help                Show this message and exit.

Commands:
  link   Manually link proxies from directory to source media in open...
  mon    Launch Flower Celery monitor in default browser new window
  purge  Purge all proxy jobs from all queues
  queue  Queue proxies from the currently open DaVinci Resolve timeline
  work   Prompt to start Celery workers on local machine
  celery Inject Celery commands to control tasks and workersConfigurationOn first run, you'll be prompted to alter your settings. The app will copy the default settings to the OS user configuration folder.Linux/Mac:$XDG_HOME_CONFIG/proxima/user_settings.yml(may not open settings automatically)Windows:%homepath%/proxima/user_settings.ymlSome Key Settingsproxy_path_rootAll proxies will be encoded to this directory. They'll retain the source media's directory structure:paths:
  proxy_path_root: R:/ProxyMediaceleryCelery runs all queuer/worker/broker communications.
Make sure you set all of the below addresses as per your environment!broker:
  url:  redis://192.168.1.19:6379/0
  job_expires: 3600 # 1 hour (cleared if not received by worker)
  result_expires: 86400 # 1 day (Needed for webapp monitor)WarningMake sure you setresult_expires!to a reasonable value otherwise Redis may run out of memory!
If you need persistent results, consider configuring Redis for persistence.workerworker:
  loglevel: INFO
  terminal_args: [] # use alternate shell? Recommend windows terminal ("wt") on Windows.
  celery_args: [-l, INFO, -P, solo, --without-mingle, --without-gossip]Queuer and worker have separate loglevels to make debugging a little easier if you've got just one worker playing up.A Note on ConcurrencySome pretty dangerous concurrency settings were moved out of the configuration settings to prevent accidents. Windows doesn't support pre-forking for concurrency. Actually, Celery doesn't officially support Windows anymore at all. Mac and Linux can pre-fork, but the worker launcher invoked with theproxima workcommand gets around this by launching separate processes with workers namedworker1@host,worker2@host, etc. We're going for the lowest common denominator here. This works fine with Mac and Linux too. It makes monitoring easier and cross-platform behaviour more consistent. For those concerned about the extra overhead who would like to squeeze out every last bit of performance on Mac or Linux, consider injecting thecelery multicommand withproxima celery.
