bigmp4

bigmp4 is an AI video enhancement service that improves footage through a browser upload or a downloadable desktop app. Its main jobs are enlarging video to 2K, 4K or 8K with noise reduction, colorizing black and white footage, raising the frame rate to 60, 120 or 240 fps through AI interpolation, and producing smooth slow motion by interpolating frames while keeping the original frame rate. It also handles GIFs and images, and a batch mode accepts a zip of many images for enlargement or colorization. The service is aimed at people restoring old family video, creators upscaling low resolution clips, and anyone who wants smoother motion without learning editing software. Supported inputs include mp4, mov, mkv, m4v, mpg, mpeg and avi video, plus jpg, png, bmp, webp and gif images. Processing happens on the vendor's GPUs, and the interface shows an estimated wait while a job runs. Desktop installers are offered for Mac and for 32 bit and 64 bit Windows, and the interface is available in about twenty languages. Usage is metered in GPU points rather than a flat subscription. The pricing modal lists packs of $6 USD for 300 GPU points, $18 USD for 1,080 points and $24 USD for 1,560 points, each with a one year expiry, payable through Stripe, PayPal, WeChat or Alipay. Free users are limited to files of 3000 by 3000 pixels and 10 MB, while paid users can upload files up to 100 MB. Paid accounts also get priority processing.
