Operating sequence
Ask the right questions for a 4K master: destination raster, source lineage, permitted processing, visual tolerance, encoding, and sign-off.
- 01
Ask what 4K means for this destination
Which exact raster, aspect ratio, frame rate, color space, dynamic range, codec, audio layout, caption format, maximum duration, and file limit does the destination require? Will the platform re-encode the master, and must that playback also be approved? What screens and viewing distance represent success? Ask whether 4K is mandatory, preferred, or merely assumed, and who may approve a lower-resolution fallback. These questions turn a broad label into a testable delivery contract without assuming that any model supplies the requested properties.
- 02
Ask how source lineage may change
May smaller sources be upscaled, and if so which transformations must be disclosed? Are crop, denoise, sharpening, interpolation, compositing, titles, and conventional footage allowed? Which original assets and processing records must be retained? Ask who verifies source dimensions and who approves hallucinated detail, temporal smoothing, or repair. Require the team to distinguish a native-size source from a 4K-raster derivative. If the current product's controls or output limits matter, request a dated authoritative source or direct account observation.
- 03
Ask for pass, fail, and fallback rules
Which defects are zero-tolerance: deformed text, facial drift, texture boiling, ringing, banding, frame duplication, crop errors, color shifts, caption failure, or audio drift? Which representative frames and motion segments need matched comparison? Who records evidence, who fixes defects, how many retries are allowed, and what triggers a 1080p delivery or a different production method? Require the final approver to sign the actual encoded master after playback. A review brief specifies expectations; it cannot establish Seedance capability, availability, pricing, entitlement, or quality.
