Batch PSD to JPEG: recoverable jobs, manifests, and bucketed presets so a midnight crash does not mean rerunning the entire library
E-commerce drops, live-ops art, and localization waves can mean thousands of PSDs overnight; if a worker dies without structured state, teams rerun everything from zero at 2 a.m. `batch-psd-jpg` is engineering-first: stable IDs, explicit state machines, retryable error classes, and output hashes in a manifest. Bright product shots and moody key art rarely share one quality factor, so bucket templates by genre and record the bucket in the manifest. When success, failure, and failure reasons are structured, ops and vendors can clear queues in parallel instead of trading screenshot dumps.
How to Use
- Pilot five files from each of three genres, confirm visible-layer logic and scaling, then shard production into parallel batches with manifest schema version, input root, output root, and parameter JSON pinned in git.
- Watch failure-rate spikes, trip circuit breakers on repeated error codes, and export failure manifests—retry by class (corrupt file, disk full, missing profile) instead of blind full reruns.
- Reconcile manifest rows to object-store keys, sample file-size distributions for anomalies, and archive manifests plus parameters with the release so audits three months later can reproduce the same pixels.
PSD to JPG (batch) FAQ
Thousands of PSDs to JPEG—how do we make jobs recoverable?
Emit manifests with paths, versions, states, error codes, and hashes; resume and retry by error class instead of full rescans.
Mixed bright/dark sets—can one quality work?
Bucket by genre with separate templates; a single global preset usually hurts half the set.
Renames break mapping—how do we prevent it?
Key on source hashes or document IDs; treat filenames as display-only and rename via controlled scripts.
Bulk jobs block urgent inserts—what helps?
Put multi-hour directory jobs on a different queue from forty-file hotfixes, each with its own concurrency cap, per-job timeout, and priority policy so urgent work is not stuck behind a five-figure folder. Huge jobs should also support subfolder chunks with mergeable manifests so only the failed shard reruns instead of the entire corpus.
Vendor JPEGs differ from ours—how to align?
Attach frozen parameter JSON, at least three golden PSDs, expected JPEG hashes, and optional automated SSIM thresholds to the SOW; both sides sign the same weekly sampling checklist instead of saying “looks close.” When outputs diverge, compare environment and JSON revisions before debating penalties—this saves days of mutual blame.
