Robust Video Matting vs Vmaker

Robust Video Matting is a free project for separating people from video backgrounds. It processes frames with a recurrent neural network that carries temporal memory, and the project says it can perform matting in real time without additional inputs. A browser webcam demo runs the model live and can visualize its recurrent states. The conversion API accepts a video or image sequence and can produce a composited video or PNG sequence, optionally including alpha and foreground outputs.

Models are available for PyTorch, TorchHub, TorchScript, ONNX, TensorFlow, TensorFlow.js, and CoreML. MobileNetv3 is recommended for most uses; ResNet50 is larger and described as offering small performance improvements. The README reports GPU throughput figures, including 4K at 76 FPS and HD at 104 FPS on a GTX 1080 Ti, and 4K at 154 FPS and HD at 172 FPS on an RTX 3090 with FP16 under specified settings. The project cautions that file conversion runs much slower because its script does not use hardware video encoding or decoding or parallel tensor transfers. CoreML models require iOS 13 or later and do not support dynamic resolution. The code is GPL-3.0 licensed.

Vmaker is a screen and webcam recording app for iOS, macOS, and Windows, with Chrome extension support also listed. It can capture webcam video, system audio, and microphone audio, and supports video quality up to 4K. The free plan is free and includes 5 GB of storage, screen recording up to 1 minute, and 20 minutes of subtitles per month. Starter costs $24 a month and includes 10 video downloads per month, screen recording up to 30 minutes, and 60 minutes of subtitles per month. Teams costs $39 a month and allows recordings up to 4 hours, with 30 video downloads and 120 minutes of subtitles per month. Starter and Teams both list a maximum upload length of 10 GB or 120 minutes. Enterprise pricing is custom; listed terms include unlimited screen recording, enhanced security and compliance, dedicated account support, and training and onboarding. The pricing note says paid plans start at $18/mo billed annually, while the listed Starter and Teams prices are monthly.
