It uses the width to determine resolution because the height may have been cut for black bars, but the width should remain the same. Notice that once you start decoding-filtering-encoding (i.e., no copy) the process will be much slower (x100 time slower or even more). If the width is between these values it will be considered that resolution already: 1 Adding to TimothyG: Video copy will ignore the video filter chain of ffmpeg, so no scaling is available (man ffmpeg is a great source of information that you will not find on Google). The video will not be scaled as it was in or near the desired resolution.The video will only be scaled to this resolution if the video is currently larger than this resolution. When checked the video will be force scaled even if the working file is already in this resolution (or near this resolution). Ffmpeg is a framework use to convert (encode or decode ) video from one format to another format. Nothing is processed in this node, and the video will be scaled once the “FFMPEG Builder: Executor” is called. When scaling it keeps the height in the same ratio as the original file and scales based on width, so it will not stretch a video’s height but rather scale it the same amount the width has been scaled to maintain the original aspect ratio. However, if “Force” is enabled, it will force the file into the resolution specified. It will compare if the file is already in that resolution, or near it (in case black bars are being trimmed etc), and if it’s near the desired resolution it will not be scaled. Options may be set by specifying - option value in the FFmpeg tools, with a few API-only exceptions noted below.
If your distribution ships with a different version, it may not get detected, or may not work correctly. resulting in 0-size files, it is most likely caused by your build of ffmpeg not having MP3 support. The video scaler supports the following named options. Caution: Audacity supports FFMPEG's libavformat in version 55 (all Audacity versions), 57 and 58 (Audacity 3.1+) and 59 (Audacity 3.2+). The following command resizes a video to be 720 pixels tall (720p), while preserving its existing aspect ratio. This node will rescale the video to the desired resolution. MPEGplayer is an MPEG video player viewer plugin. FFmpeg: Resize the video then convert it.
