What you can do: - Convert formats. - Video to Audio. - Create video from images and sounds.The main principle of video compression is to control the size of the video by adjusting parameters related to video quality and effect, such as resolution, bit rate and frame rate. Frame rate: the number of pictures played per second, the smaller the frame rate, the more you see the video will be stuck and the action will be incoherent.There will be 4 options for you to choose: upscale resolution, optimize brightness & contrast, remove video noise and reduce video shaking. If you only need to upscale resolution, then tick the first box above. And don't forget to Apply. Step 5. Now go back to the main interface. And click the Settings next to Profile.1 Lossy codecs such as x264 degrade the image quality by design, if you don't want to lose image quality you either have to use a lossless codec or better yet, not re-encode at all.

Additional tests revealed other issues. Nearly optimal compressionQuality Besides that, the quality of the GIF is also suboptimal as a GIF file is limited to only 256 colors. By default, FFmpeg uses a generic 256-color palette for every GIF encoding and doesn't take into account the colors in the input video.Running in low-latency mode shows an even larger advantage for the T4. It can encode 37 streams at 720p resolution, 17-18 in 1080p, and 4-5 streams in Ultra HD, which is 2-2.7x higher performance than libx264 with higher visual quality.
