To the best of our knowledge, AlphaVC is the first E2E AI codec that exceeds the latest compression standard VVC on all common test datasets for both PSNR (-28.2% BD-rate saving) and MSSSIM (-52.2% BD-rate saving), and has very fast encoding (0.001x VVC) and decoding (1.69x VVC) speeds. With these powerful techniques, this paper proposes AlphaVC, a high-performance and efficient learned video compression scheme. Third, we propose a probability-based entropy skipping method, which not only brings performance gain, but also greatly reduces the runtime of entropy coding. It’s the most efficient way to compress your video files for a smaller size. Second, to efficiently improve the accuracy of inter prediction without increasing the complexity of decoder, we propose a pixel-to-feature motion prediction method at encoder side that helps us to obtain high-quality motion information. Lossy compression means that a compressed file will contain less data than the original one. Freeconvert is a surprisingly powerful free video compression tool. HOW TO COMPRESS A VIDEO ONLINE Add your media file from your computer, Dropbox, or Google Drive. First, to address the problem of accumulative error, we introduce a conditional-I-frame as the first frame in the GoP, which stabilizes the reconstructed quality and saves the bit-rate. Free online video compressor: Freeconvert. Video compressor will make your video smaller, easy and free. Lossless compression reduces bits by identifying and eliminating statistical redundancy. 2 Any particular compression is either lossy or lossless. Reduce file size of videos, PDF documents, MP3 audio files and images. In information theory, data compression, source coding, 1 or bit-rate reduction is the process of encoding information using fewer bits than the original representation. In this paper, we propose several techniques to effectively improve the performance. Compress video file to get the same video quality but less file size. Compress MP4, MOV, MP3, PDF, PNG, JPG, JPEG, GIF files online for free. In general, video compression is widely adapted for all. However, the previous works still suffer from some criticial issues and have a performance gap with traditional compression standards in terms of widely used PSNR metric. State-of-the-art video compression techniques play a vital role in coding and decoding of video images that consume enormous memory space.
