![]() If you're certain it's exactly 4:3, of course, just use 104:135. It could be 4:5, I suppose (very close to 104:135), but I don't know of anything that produces that pixel aspect ratio maybe try that first, and then try 3:4 if it still looks a little too stretched horizontally. Here's the question, I'm not aware of ECMA scripts, how to make a script which will be loaded at the CLI and proceed to do me the right processing. If your video is 1920 X 1080 then apply 960 on the left to crop. I saw in the package some ready functions, like /share/ADMscripts/video/filter.js. Apply half of the width of your video to either left or right to crop from. It's 720 wide, which suggests a DVD source it's a 25 fps video, suggesting PAL, but the PAR works out to less than 1, suggesting NTSC. April 19, 2014, 04:40:21 PM Hello, I'd like to apply resizing to a bunch of video, via batch it's preferred. avi video with Avidemux and I set Video format to MPEG-4 AVC(under Configure, Bitrate tab I choose Single Pass - Bitrate (Average) and Target bitrate to 256. ![]() If the source represents true SD NTSC pixels (in which case only the central 704×480 pixels are supposed to map to a 4×3 screen, with 8 pixels overscan on either side), the correct command would be: mp4box source.mp4 -out target.mp4 -par 1=10:11īecause (4/3) / (704/480) = 10/11 – exactly the reference pixel aspect ratio for standard definition NTSC video.įor the case given in the question, if it's really 4:3, that gives a very odd pixel aspect ratio: (4/3)/(720/416) = 104/135. Tip: You can find out the exact video height and format in AVIDemux video information Alt Return or in top menu - File Information. They are both under Video > Filters > Transform. For this case, you need: mp4box source.mp4 -out target.mp4 -par 1=8:9 What I do is indeed Crop and then Resize to the correct aspect ratio. (Equivalently, you're describing the aspect ratio of a source pixel.) For example, suppose you have a DVD source that's 720×480, and the correct display aspect ratio is 4:3. ![]() When you use -par stream-number=width:height, you define the pixel aspect ratio – that is, the result of dividing the device aspect ratio by the storage aspect ratio. With an -out parameter (so as not to disturb your original file): mp4box source.mp4 -out target.mp4 -par stream-number=width:height 16 Reviews Downloads: 234 This Week Last Update: Download Summary Files Reviews Support Project Activity See All Activity > Categories Non-Linear Video Editing License GNU General Public License version 2. In this example we are working with a video that has a 4:3 aspect ratio. Delgado's answer is correct that MP4Box can do this, but the -par option doesn't work quite as described. Crop video footage in 1:1, 9:16, 16:9, 4:3, and more to change the aspect ratio.
