What was wired in
I re-encoded a generated market clip at 120 kbps to break it into blocks. The LoRA removes the blocks, and the fruit and the crowd come back clean and close to the original.
Reference shows a market stall under a green and white striped awning where a vendor with a grey beard in a blue apron is arranging oranges, red apples and yellow bananas in wooden crates while a customer in a dark red headscarf reaches for lemons, with a busy market crowd behind, heavily compressed with visible macroblocking, chroma bleed, and ringing artifacts. Edited shows the same scene restored to high quality with sharp detail, clean edges, and no compression artifacts. ENHANCE QUALITY a market stall under a green and white striped awning where a vendor with a grey beard in a blue apron is arranging oranges, red apples and yellow bananas in wooden crates while a customer in a dark red headscarf reaches for lemons, with a busy market crowd behind. Subject identity, framing, and background geometry are identical to the reference; only compression artifacts and image quality differ between reference and edited.
Notes
It came out so close to the original that I tried footage that was never clean next. The trigger is ENHANCE QUALITY, and it only helps footage that is badly damaged.
