Too stupid to rotate :D

[oxivanisher]

Hi all

I really love this project. It helps me with a problem i have since three years and my sister finally will have a wedding video and not only photos. But now i am facing a problem.
I try to rotate the Images which are somehow not rotated from ffmpeg. The EXIF rotation tag allows me to detect if the image is "wrong", so that is not a problem. But i don't know how to use rotation correctly. Here is my test code:

if imgData['orientation'] == 1:
    clips.append(ImageClip(imgData['path']).resize(height = HEIGHT).set_pos('center').set_start(clipStart).fadein(FADEIN).set_duration(IMGDURATION).crossfadeout(FADEOUT)) #, width = WIDTH
else:
    #please rotate the image...
    clip = ImageClip(imgData['path']).resize(width = HEIGHT).set_pos('center').set_start(clipStart).fadein(FADEIN).set_duration(IMGDURATION).crossfadeout(FADEOUT)
    clip1 = vfx.rotation(clip, -90)
    video = CompositeVideoClip([clip1], size = MOVIESIZE)
    video.to_videofile(DSTPATH + "/video.avi", fps=25, codec=CODEC)

I tried around and fiddled with it, but did not get behind how to do this correctly. Finally all these images are put into a list (clips) and rendered over another background video. This video rendering here is just for testing purposes.
The error output i get is:

  File "/usr/local/lib/python2.7/dist-packages/moviepy/video/VideoClip.py", line 325, in blit_on
    return blit(img, picture, pos, mask=mask, ismask=self.ismask)
  File "/usr/local/lib/python2.7/dist-packages/moviepy/video/tools/drawing.py", line 43, in blit
    1.0 * mask * blitted + (1.0 - mask) * blit_region)
ValueError: operands could not be broadcast together with shapes (3,717,3) (3,1080,717)

Can you give me a hint how to do this right?
Thanks and have a nice day. :)

This was a bug, I just fixed it on github and pypi. Tell me if it works !

[oxivanisher]

I will tell you as soon as i can. Probably in about 12 hours.

Yeah sure, no hurry, have a nice day :)

[oxivanisher]

It works like a charm! Thank you very much 💃

I know this a long shot, but @oxivanisher can you tell me where you got your imgData['orientation']? I am trying to find a way for python to automatically find the orientation, and nothing has come up yet. Thanks

Hi @Gloin1313

It took me some digging to find this 3 year old script, but i did get lucky. I used the following code (just copy & pasted the relevant stuff):

from moviepy.editor import *
from PIL import Image as PILImage
from PIL import ExifTags

for filepath in files:
    data = []
    img = PILImage.open(filepath)
    exif = {
        ExifTags.TAGS[k]: v
        for k, v in img._getexif().items()
        if k in ExifTags.TAGS
    }

    data.append({'path'       : filepath,
                 'camModel'   : exif['Model'],
                 'camMake'    : exif['Make'],
                 'orientation': exif['Orientation'], })

and then further down

    if imgData['orientation'] == 1:
        clip = ImageClip(imgData['path']).resize(height = HEIGHT).set_pos('center').set_start(clipStart).fadein(FADEIN).set_duration(IMGDURATION).crossfadeout(FADEOUT) #, width = WIDTH
    else:
        clip = vfx.rotation(ImageClip(imgData['path']).resize(width = HEIGHT).set_pos('center').set_start(clipStart).fadein(FADEIN).set_duration(IMGDURATION).crossfadeout(FADEOUT), 90)

Hopefully this helps :)
