ImageSource fails with different types of images

[pixaeiro]

Hello,

I am trying to render a video using ImageSource but I am getting error messages when I mix different file types.
For example, these two scripts are ok:

------------
v00 = ImageSource( "C:/VideoSamples/AviSynthScripts/ImgsBad/frame-00001.bmp", 0, 100, 25.0 )
v01 = ImageSource( "C:/VideoSamples/AviSynthScripts/ImgsBad/frame-01762.bmp", 0, 100, 25.0 )
video = v00 + v01
audio = WAVSource( "C:/VideoSamples/Material/Audio/1.PixaFluxIs.wav" )
AudioDub( video, audio )
------------
v00 = ImageSource( "C:/VideoSamples/AviSynthScripts/ImgsBad/groundhog.png", 0, 100, 25.0 )
v01 = ImageSource( "C:/VideoSamples/AviSynthScripts/ImgsBad/beaver.png", 0, 100, 25.0 )
video = v00 + v01
audio = WAVSource( "C:/VideoSamples/Material/Audio/1.PixaFluxIs.wav" )
AudioDub( video, audio )
------------

But this script:
------------
v00 = ImageSource( "C:/VideoSamples/AviSynthScripts/ImgsBad/frame-00001.bmp", 0, 100, 25.0 )
v01 = ImageSource( "C:/VideoSamples/AviSynthScripts/ImgsBad/frame-01762.bmp", 0, 100, 25.0 )
v02 = ImageSource( "C:/VideoSamples/AviSynthScripts/ImgsBad/beaver.png", 0, 100, 25.0 )
video = v00 + v01 + v02
audio = WAVSource( "C:/VideoSamples/Material/Audio/1.PixaFluxIs.wav" )
AudioDub( video, audio )
------------

Fails with this error message:
------------
Splice: Video formats don't match
(C:\VideoSamples\AviSynthScripts\ImgsBad\script_bad temp files\script_bad_Source.avs, line 4)
------------

And the worst part is that it fails even when all files are BMPs saved by different applications, say one saved by GIMP and the other saved by PhotoShop.

Is there a rule about this? Or is this a bug?

Thank you!

Use Info to see if there are differences. There might be RGB24 and RGB32.

Thanks creaothceann.
I tried again with an image saved in GIMP and this is the message I get:
--------------------------
ImageReader: EBMP reader cannot handle compressed images.
(C:\VideoSamples\AviSynthScripts\ImgsBad\script_bmp_gimp temp files\script_bmp_gimp_Source.avs, line 2)
--------------------------
Unfortunately GIMP doesn't have any options to export BMP images that are not compressed.

ImageSource() works fine here with GIMP BMP images

You have other options for export like TIFF, or losslessly compressed PNG as well

Something else is going on, or you're not exporting from GIMP correctly

add "converttorgb32 ()" to every imagesource command line
and happy Halloween!

Thank you!
Yes, I had to modify my exporter to save the frames as PNG files instead of BMP and now it works correctly.
The BMP files were fine. I can open them in any other application I have tried.

Use use_DevIL=true when loading bmp images that the internal parser doesn't support.

You will get that message if the height/width of the images don't match. What is the format size of the png's and of the bmp's?

You will get that message if the height/width of the images don't match.
No - in that case, you get the message "Frame sizes don't match".
"Video formats don't match" means the clips have different color spaces - that's why pixaeiro was able to fix it by converting everything to RGB32.
