![]() This website contains lots of information about downloading, compiling, configuring, and using the program. So in conclusion, for direct resizing/scaling you can use the terminal ones. Avidemux is a free open-source program designed for multi-purpose video editing and processing, which can be used on almost all known operating systems and computer platforms. OPENSHOT & PITIVI - Both are good video editors tha can help lower size when rendering the video. Adding a display of output AR to the crop and resize filters is a trivial to implement improvement. In a GUI using an external calculator shouldnt be required. I use it a lot when going from ogg to mp4 with h.264. Why cant Avidemux crop filter UI do this - The current swsResize UI isnt much help at all. HANDBRAKE - Excellent tool for converting videos and optimizing size. Where -i is for the original input file, -s is for the size for each frame and the name of the output final goes in the end.ĪVIDEMUX - It can resize and lower the size which helps in cases where the objective is to lower size. To Run - avconv -i input.mp4 -s 640x480 output.mp4 To Install - sudo apt-get install libav-tools In this case you are dividing the original size by 2 (iw/2)īoth of which can provide more information if you either execute them without parameters or variables like just mencoder or ffmpeg or type for example man mencoder or man ffmpeg which will give you a VERY extensive little manual on how to work with them. Install it by sudo apt-get install ffmpeg Mencoder input.mp4 -vop scale=640:480 -o output.mp4Īlthough from my experience is better to include additional information for video and audio like the one above. Mencoder input.mp4 -ovc lavc -lavcopts vcodec=mp4 -vf scale=640:480 -oac copy -o output.mp4 Mencoder input.mp4 -ovc lavc -lavcopts vcodec=mp4 -vop scale=640:480 -oac copy -o output.mp4 This is normal if you want to reduce bandwidth use, lower video size, etc. The part about mencoder that you want is the parameter -vop scale which tells mencoder to what scale you want the video to go to. Install it by sudo apt-get install mencoder Terminal commands (Which by default are not installed) are:
