the -vf invokes the scale video filter which actually rotates and crops the clip) There may be better options but this one worked for me. i used the -ovc lavc because i could not make mencoder simply copy and needed to pick some codec. Here are my notes on a successful attempt.įor files that were shot in portrait (90 degree angle).

As a compromise, I ran all the files through the same basic process and got a single avi with the audio in sync with the video. The basic problem I ran into was that despite all my best efforts, I was unable to match the rotated file to the original specifications for the files and, as a result, the sound was always wildly out of sequence. In order for them to match the other clips, i had resize the rotated clips to the standard format (320 wide x 240 high), and conconcatinate them into a single avi file. In needed to rotate them, making them 240 wide x 320 high). The problem was that some clips were shot in portrait (i.e. Here is what i did to assemble several clips into a single avi file. I was working on my own solution but its in no way as elegant as yours.

IMAGEMAGICK ROTATE CODE

Don't forgot the code tag () for your commands and console outputs. I forgot to mention "-framerate" in my last post but I updated it. You can then use dvdauthor () to assemble the mpeg program streams () into a suitable DVD filesystem. If you want a PAL output, use "-target pal-dvd". crop usually centers the cropping, but this example will cut off the bottom. This uses the transpose (), crop (), and pad () video filters. Since re-encoding is required (because of the padding and because you want DVD video) you can just use ffmpeg to do everything:įfmpeg -i MVI_0183.AVI -vf "transpose=1,crop=iw:240:0:0,pad=320:240:(ow-iw)/2:0" -target ntsc-dvd output.mpg

IMAGEMAGICK ROTATE HOW TO

You can also crop losslessly with jpegtran, but I'm not sure how to add the borders without re-encoding. ffmpeg -framerate 15 -i frames/frame_%d.jpg -i MVI_0183.AVI -codec copy -map 0:v -map 1:a rotated.avi Default input frame rate is 25, so you may have to change it to match your original input: Mux the images into a video, and mux the audio from MVI_0183.AVI (again, no re-encoding is needed). You can do this losslessly with exiftran: ffmpeg -i MVI_0183.AVI -codec:v copy -bsf:v mjpeg2jpeg frames/frame_%d.jpg This will use stream copy () mode and extract the actual jpg images (in addition to using the mjpeg2jpeg bitstream filter ()) instead of re-encoding them. MJPEG is basically just a bunch of jpg images. Tar xzvf ffmpeg.static.32bit.$(date +"%F").tar.gz

IMAGEMAGICK ROTATE DOWNLOAD

Ubuntu doesn't use the real ffmpeg but you can easily download it: You can skip imagemagick, and you can even perform the rotation losslessly: Interleave, duration : 800 ms (12.00 video frames) A more complete set of specifications is provided below: My next step is to use ffmpeg to reassemble the video. Mogrify -path temp -format png -gravity south -chop 0x80 -background black -extent 320x240 *.pngĤ. When i was satisfied that the images were right, i used this command below: I wanted to crop the bottom off the bottom of the image to make it 240x240 and then add a black border so that the rotated image returned to a 320x240 frame size. Then I made a directory temp inside directory image_dump so that I could preserve the above work and experiment a little. turn them on their side (images are now 240 x 320)ģ.

IMAGEMAGICK ROTATE MOVIE

strip individual images out of the movie (images are now 320x240)Ģ. In case you are interested, here are my steps to date.ġ. The orginal movies have the following specifications:ĭuration: 00:00:03.19, start: 0.000000, bitrate: 2361 kb/s The question I am asking how can I use ffmpeg to create a movie from the images that is compatible with the originals. After that i hope to add the sound back in like a sound track. I am trying to export the avi movie to images using ffmpeg, editing them using imagemagick, and then reassembling them as an avi in a mode that matches the orginal movie. to rotate the films but the video frames become very uneven and the sound is far out of sync. I've tried many solutions like avidemux, etc. One of the clips was rotated at a 90 degree angle. The movies were all shot with the same camera. I am making a movie out of many avi clips. The question I am asking how can I use ffmpeg to reassemble a movie clip from the images that is compatible with the original movies from which they were derived. I am following the example for rotating movies 90 degrees using ffmpeg and imagemagick as suggested in another thread ().
