![]() When we scale an image without specifying the size, the input dimension is used as the default value. The libswscale library contains video image scaling and colorspace/pixelformat conversion routines. In other words, a 480p video has a resolution of 852×480 pixels.2 What is the resolution of 720p?ġ280×720 pixels Can FFmpeg resize an image?įFMpeg is using the libswscale library to resize the input. So, a 480p video is made up of 480 lines stacked one on top of another, with each line being 852 pixels wide. To set the bitrate target in FFmpeg, use the -b:v code (bitrate:video) below : ffmpeg -i Test_1080p. 265 (no change in resolution) ffmpeg -i input.mp4 -c:v libx265 -vtag hvc1 -c:a copy output.mp4. Convert 4k to 1080 (no change in codec) ffmpeg -i input4kvid.mp4 -vf scale=1920:1080 -c:a copy output1080vid.mp4.ffmpeg -i input.mp4 -vf scale=480:-1 output.mp4.Download and Install FFmpeg to Your Computer.ffmpeg -i input.mp4 -vf scale=-1:720 output.mp4. Specify the Height To Retain the Aspect Ratio.The resulting video will have a resolution of 320×180. ffmpeg -i input.mp4 -vf scale=320:-1 output.mp4. Specify the Width To Retain the Aspect Ratio.How to Change the Video's Resolution but Keep the Aspect Ratio? We have presented a wealth of illustrative examples to show how the Ffmpeg Resolution 720*480 problem can be solved, and we have also explained how to do so. Ffmpeg -i input.avi -s 720x480 -c:a copy output.mkv
