Rotating avi file using ffmpeg and imagemagick

[rioguia2]

I am following the example for rotating movies 90 degrees using ffmpeg and imagemagick as suggested in another thread. 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 making a movie out of many avi clips. The movies were all shot with the same camera. One of the clips was rotated at a 90 degree angle. I need to rotate it. I've tried many solutions like avidemux, etc. to rotate the films but the video frames become very uneven and the sound is far out of sync. 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. After that i hope to add the sound back in like a sound track.

The question I am asking how can I use ffmpeg to create a movie from the images that is compatible with the originals. The orginal movies have the following specifications:

ffmpeg -i MVI_0183.AVI

Input #0, avi, from 'MVI_0183.AVI':
  Metadata:
    creation_time   : 2003-08-16 11:02:42
    encoder         : CanonMVI01
  Duration: 00:00:03.19, start: 0.000000, bitrate: 2361 kb/s
    Stream #0.0: Video: mjpeg, yuvj422p, 320x240, 15 tbr, 15 tbn, 15 tbc
    Stream #0.1: Audio: pcm_u8, 11024 Hz, 1 channels, u8, 88 kb/s

In case you are interested, here are my steps to date.

1. strip individual images out of the movie (images are now 320x240)

ffmpeg -i MVI_0183.AVI image_dump/%d.png

2. turn them on their side (images are now 240 x 320)

mogrify -rotate 90 image_dump/*.png

3. Then I made a directory temp inside directory image_dump so that I could preserve the above work and experiment a little. 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. When i was satisfied that the images were right, i used this command below:

mogrify -path temp -format png -gravity south -chop 0x80 -background black -extent 320x240 *.png

4. My next step is to use ffmpeg to reassemble the video. Something like this???

ffmpeg -i temp/%d.png -o output.avi
