  "account": "Browser-based video editing tool allows users to swap backgrounds in video clips, keeping the original file on their device. The service offers three models with varying sizes - compatible, quality-focused, and experimental, for non-commercial testing. The compatible model, chosen for its small size, was used to test three free clips from Wikimedia Commons, all in the public domain.\n\nThe first test involved a man, Tarun, speaking at an event. The tool worked well for him, with clean hair and shoulder lines at 4 seconds. However, issues arose with other elements in the frame; faint specks and ghosting of a projector screen appeared above his hair and the women standing beside him were partially removed, leaving a semi-transparent smear.\n\nNext, the tool was tested on a person juggling under purple light. At 3 seconds, fast-moving hands became semi-transparent, while at 5 seconds, the raised hands were also partly hidden. The curly hair held its outline better than the hands.\n\nThe most significant issue was observed in a street performance clip of folkloristic dance in Naples. At 2 seconds, people overlapping in the middle turned semi-transparent, and at 11 seconds, a group of five individuals on the left disappeared along with the street behind them. The front row of lighter-clad people remained visible throughout. Additionally, a gradient background showed through the lower half of the people in front at 6 seconds, and the faraway crowd was successfully removed.",
