How to Use vxpeViewer — Tips, Tricks, and Best PracticesvxpeViewer is a lightweight, fast viewer designed for inspecting, annotating, and analyzing files and visual data produced by vxpe-format tools and related pipelines. Whether you’re a developer debugging data flows, a designer reviewing exported assets, or an analyst annotating frames, this guide covers the core workflows, practical tips, and best practices to get the most from vxpeViewer.
What vxpeViewer is and when to use it
vxpeViewer focuses on quick, efficient visualization and lightweight annotation. It’s not a full editing suite; instead, it’s optimized for:
- rapid preview of vxpe-exported files and visual logs,
- frame-by-frame inspection,
- lightweight metadata viewing and tagging,
- sharing annotated snapshots or short sequences with colleagues.
Use vxpeViewer when you need speed, clarity, and collaboration-ready exports without heavy editing.
Installation and initial setup
- Download the latest vxpeViewer build from the official distribution channel for your OS (Windows, macOS, or Linux).
- Install per platform instructions (Windows: installer; macOS: drag-to-Applications; Linux: package or AppImage).
- Launch vxpeViewer and configure preferences:
- Default folders for recent projects,
- GPU/CPU rendering mode (use GPU for large sequences if available),
- Keyboard shortcuts (customize for your workflow),
- Default export settings (PNG/JPEG quality, annotation flattening).
Tip: Keep the application updated — releases often include performance and rendering fixes.
Supported file types and formats
vxpeViewer handles:
- native vxpe container files and exports,
- common image formats (PNG, JPEG, TIFF),
- animated sequences (image sequences, GIF),
- video files (MP4, MKV — see codec notes),
- basic JSON/YAML metadata sidecars.
If you work with exotic codecs, convert to a supported format (e.g., H.264 MP4) before loading into vxpeViewer.
Core interface overview
- Main canvas: displays the current frame or image.
- Timeline/frame scrubber: jump between frames, set range in sequences.
- Layer/track panel: view available overlays, masks, and metadata layers.
- Inspector/meta panel: shows per-frame metadata, key-value pairs, timestamps.
- Annotation toolbar: draw, highlight, add text, place markers.
- Export/share button: save snapshots, annotated sequences, or export sidecar metadata.
Keyboard shortcuts drastically speed up navigation—learn the ones for play/pause, next/previous frame, zoom, and annotation toggle.
Basic workflows
Opening and previewing files
- Drag-and-drop a file or use File → Open.
- For sequences, point the dialog to the folder or the sequence’s numbering pattern.
- Use play controls for quick playback; adjust playback speed when reviewing long sequences.
Navigating frames and zoom
- Use the timeline or arrow keys to step frames.
- Zoom with mouse wheel or pinch gestures; double-click to fit-to-window.
- Use pan (space + drag) for precise inspection.
Viewing metadata and overlays
- Open the Inspector panel to see frame-specific metadata such as timestamps, sensor data, or custom fields.
- Toggle overlays (masks, heatmaps) from the Layer panel to compare raw and processed results.
Annotations and notes
- Use the annotation toolbar to add rectangles, arrows, freehand strokes, and text labels.
- Choose colors and stroke widths to match your team’s conventions (e.g., red for errors, green for confirmed items).
- Attach short notes to markers; notes appear in the inspector and can be exported in sidecar JSON.
Exporting results
- Export a single annotated frame as PNG/JPEG or export a range as an image sequence.
- Flatten annotations when needed (merge with image) or keep them as separate sidecar files for later editing.
- Use batch export to create thumbnails or compressed MP4 previews for sharing.
Advanced techniques and tips
Batch processing sequences
- Use the batch export dialog to apply the same annotation flattening, resizing, or re-encoding to many files.
- For large datasets, enable GPU rendering and increase memory cache limits in Preferences.
Scripting and automation
- vxpeViewer provides a simple scripting API (Python/JS) for automating repetitive tasks like exporting timestamps, generating contact sheets, or applying consistent annotations across a set.
- Typical script tasks:
- load sequence,
- iterate frames,
- apply marker or metadata patch,
- export snapshots.
Color management and accurate previews
- Enable color profile support to match production color spaces.
- For critical reviews, toggle soft-proofing to preview output in a target color space.
Comparisons and diffing
- Use split-view or onion-skin modes to compare two frames or versions.
- Adjust opacity and alignment to highlight differences.
Performance tuning
- Reduce cache size if memory is constrained; increase it for smoother scrubbing on large files.
- Prefer proxies (lower-res versions) for playback; switch to full resolution for final inspection.
Collaborative review
- Use the share/export features to generate a review package: compressed preview video, annotated keyframes, and a sidecar JSON with all markers and notes.
- Standardize annotation labels and colors across the team so exported notes are consistent and machine-readable.
Troubleshooting common issues
Playback stutters
- Switch to GPU rendering, lower playback resolution, or use proxy files.
Missing metadata
- Ensure sidecar JSON/YAML is in the same folder and matches file names. Use the import metadata feature if necessary.
Annotations won’t export correctly
- Check whether you exported with “flatten annotations” disabled (sidecars only) or enabled (embedded). Re-export with the desired option.
Unsupported codec
- Convert video to a supported codec (H.264 in MP4 is safest) and reopen.
Best practices checklist
- Keep vxpeViewer updated.
- Use GPU rendering for large sequences when available.
- Standardize annotation colors and labels across projects.
- Save annotations as sidecars when you need non-destructive review.
- Use proxies for smooth playback, full-res for final checks.
- Export consistent review packages (preview video + annotated keyframes + sidecar).
Example quick workflows
Inspect & share a bug report (2–3 minutes)
- Open the sequence and jump to the failing frame.
- Add an arrow and short text note.
- Export the annotated frame as PNG + sidecar JSON and attach to your ticket.
Create a weekly review package
- Batch-export keyframes from each sequence.
- Generate a compressed MP4 preview (low bitrate) for quick viewing.
- Bundle annotated frames and sidecars and upload to your team drive.
Resources and further learning
- Official vxpeViewer documentation and release notes for version-specific features.
- Scripting API guide and example scripts (look for Python/JS snippets).
- Team conventions doc for annotation standards and review workflows.
vxpeViewer is a focused tool that speeds up visual inspection and collaborative review without the overhead of heavy editing suites. Using the tips above — proxies for playback, sidecars for non-destructive notes, standardized labels, and automation for repetitive tasks — will make reviews faster, clearer, and more consistent.
