EXR sequence import output issues

[anton_foy]

Hi,

When I use this below output is correct but it can only use 1 frame and not a sequence (48 frames in the sequence):

FFVideoSource("F:\tester\frame_0000.exr", cache=true)
z_ConvertFormat(pixel_type="YUV444PS", colorspace_op="rgb:linear:709:full=>709:linear:709:full")

neo_vd().removegrain(2)

ConvertBits(32)
z_ConvertFormat(pixel_type="RGBPS", colorspace_op="709:linear:709:full=>rgb:linear:709:full")
prefetch(16)

then ffmpeg:
ffmpeg -i exr.avs -c:v exr -pix_fmt gbrpf32le avs_seq_%04d.exr

But when using this below to be able to input the whole sequence the output is incorrect because when I import the exr sequence to davinci resolve the information in in highlights are lost and clipped:

ImageSource("F:\tester\frame_%04d.exr", start=0, end=48, fps=25, use_DevIL=true, pixel_type="RGB64")
ConvertToPlanarRGB()
z_ConvertFormat(pixel_type="YUV444PS", colorspace_op="rgb:linear:709:full=>709:linear:709:full")

neo_vd().removegrain(2)

ConvertBits(32)
z_ConvertFormat(pixel_type="RGBPS", colorspace_op="709:linear:709:full=>rgb:linear:709:full")
prefetch(16)

then ffmpeg:
ffmpeg -i exr.avs -c:v exr -pix_fmt gbrpf32le avs_seq_%04d.exr


Any idea how I can get the same output as the first script but importing the whole sequence? Thanks

LwLibavVideoSource can handle image sequences also. Something like LwLibavVideoSource("output_%02d.jpg") # or output_%02d.png

Thanks but sadly Avisynth open failure: LwLibavVideoSource: gbrpf32le is not supported
