How to Use Elecard StreamEye Studio for Professional Video Quality Analysis

1) Quick overview

Elecard StreamEye Studio is a professional suite for deep video-bitstream inspection, objective quality measurement and batch QA. Main components: StreamEye (bitstream/codec-level analysis), Video Quality Estimator (PSNR/SSIM/VMAF and more), Stream Analyzer (syntax/stream validation), YUV Viewer (raw-frame inspection) and Quality Gates (comparative QA). Command-line tools enable automation.

2) Typical workflow (step-by-step)

1. Prepare inputs: collect encoded streams (TS/MP4/elementary) and a reference YUV or decoded reference if available.
2. Open stream in StreamEye: inspect container/stream structure, access headers, GOPs, and frame list.
3. Navigate to trouble frames: use thumbnails/GOP view to find visible artifacts or encoder anomalies.
4. Inspect coding details: view macroblock/CTU partitioning, motion vectors, prediction types, transform coefficients, quantizers, filters and slice/tile boundaries to locate cause.
5. Compare visually: load reference and use side-by-side, split, subtraction, temperature or PSNR-clip modes in StreamEye or YUV Viewer to see per-frame differences.
6. Run objective metrics: use Video Quality Estimator to compute PSNR, SSIM, DELTA, VMAF (and VMAF phone), VQM, NQI, VIF, etc., over the whole sequence or selected intervals.
7. Use Quality Gates for batch: run multiple encoded variants to rank encodes, get pass/fail against thresholds and collect summary charts.
8. Automate with CLI: create config XMLs and run StreamEye Console / Video Quality Estimator Console to generate CSV reports for CI or large-scale testing.
9. Interpret results: correlate objective metrics with visual findings and bitstream details (e.g., high QP spikes, bitrate allocation shifts, reference-frame issues).
10. Report & iterate: export screenshots, CSV metrics, and annotated notes; adjust encoder settings and re-test.

3) Key checks to perform

• Bitrate & bit distribution: look for sudden drops/spikes and per-GOP allocation.
• Quantizer behavior: identify frames/regions with very high QP.
• Motion vector & prediction anomalies: mismatches, wrong references or lost ref frames.
• Transform/residual patterns: blocking, ringing, or missing residuals.
• Color/gamut issues: verify BT.709/BT.2020 selection and YUV formats.
• Sync & timing: frame order, PTS/DTS and decoder buffer (VBV/DPB) behavior.
• Objective vs subjective: check where metrics (e.g., VMAF) disagree with visible quality and investigate causes.

4) Practical tips

• Use thumbnails and GOP overview to quickly locate problematic scenes.
• For codec debugging, enable display of residuals, dequantized coefficients and hex viewer.
• When VMAF seems off, inspect chroma upsampling, color space conversion and reference alignment.
• Save CSV outputs and integrate into CI for regression monitoring.
• Take advantage of Elecard’s video tutorials and user guides (downloadable from Elecard site) for codec-specific visualizations.

5) Deliverables you can export

• Per-frame metrics CSV (PSNR/SSIM/VMAF/etc.).
• Bitstream summary and hex dumps.
• Annotated screenshots and side-by-side comparison images.
• Automation scripts/config XML for repeatable tests.

If you want, I can:

• produce a ready-to-run StreamEye Console config XML for a sample PSNR+VMAF run, or
• create a short checklist tailored to H.264/H.265 or AV1 encoder validation. Which would you prefer?
