Can My Computer Edit This Footage? — Proxy or Native Check — Can your computer edit 4K H.265 without proxy? — honest browser-local check You export a edit readiness checker file and the numbers look wrong. Can My Computer Edit This Footage? — Proxy or Native Check gives a single deterministic verdict from your own inputs, in your browser, without upload. For edit readiness checker, inputs stay on your device. The useful question isn't theory but what your specific edit readiness checker does against the documented line. A chatbot can describe edit readiness checker broadly, but it can't judge correlation 0.58 at 42 ms without computing. Enter values you already have — correlation and delay, bitrate and dimensions, or URL and status — and receive ok / warning / critical plus a next step you can try in ten minutes. Teams shipping weekly have learned the cost of skipping this: edits blocked, tests with tiny samples, codecs a client can't play. This is the short gate before that rework.

Three real creator examples — not toy numbers

Note for Can your computer edit 4K H.265 without proxy? — edit readiness checker: The following three scenarios are hypothetical examples (illustrative, not sourced case studies) for this specific tool — they show the shape of real usage but are not measured exports or lab captures. Where we cite a measured session, we say so and give method. Near the line (warning) for edit readiness checker: 0.58 at 42 ms for two voices 1.2 m apart, untreated room, 48 kHz USB — bleed yes, warning. Fix: add 60 cm, angle 90° off-axis, or gate near -28 dB. At 1.8 m it falls to 0.41 at 58 ms → ok. Fails openly (critical) for edit readiness checker: 0.88 at 12 ms with two omni lavs 30 cm apart — critical, comb-filter near 42 and 83 Hz. Change pattern or isolate; software shaves ~6 dB. Passes clean (ok) for edit readiness checker: 0.22 at 120 ms for a remote double-ender, each guest local, drift <0.3 ms per hour, aligned by clap — ok, room tone plus network lag, not bleed. Align and cut.
