Problem
Proxy generation creates unusable files because the chosen proxy format is not supported by the destination workflow.
Solution
Root Cause / Diagnostic:
Generating proxies with incompatible codec profiles, unsupported color bit-depths, or non-standard frame dimensions causes destination editing systems or mobile review workflows to reject the files. For instance, creating ProRes 422 proxies for Windows-based editors without ProRes decoders, or generating 10-bit H.265 proxies for legacy mobile devices, results in black frames, playback crashes, or unsupported file format errors.
Actionable Fix:
1. Standardize proxy generation on universally supported codecs: choose Apple ProRes Proxy for macOS environments or Avid DNxHR LB / 8-bit H.264 (CFR) for cross-platform workflows.
2. Maintain identical frame rates, audio track layouts, and aspect ratios between proxy and camera master files, downscaling resolution cleanly to 1920x1080.
3. Test-open sample proxy files across all target client devices and editing systems to confirm instant playback and metadata compatibility.
Pro Tip:
Configure proxy presets to preserve source camera audio track configurations (e.g., 4-channel discrete audio); mismatched audio channels will prevent NLEs from successfully attaching proxies.
