Avisynth ImageSource Problem

[SingleRottenChip]

I am a newbie to Avisynth. And I'm trying to run this Avisynth script I found online to test whether a frame has any 720p detail.

I run it with PotPlayer, MPC-HC, VLC, and Windows Media Player, but all of them show that a decoder named " G3" cannot be found.

Here's the script.

ImageSource("C:\Users\D9043\Desktop\test.png")

ConvertToPlanarRGB()

source = last

z_Spline36Resize(1280, 720, dither="error_diffusion")

subtitle("720p upscale")

z_Spline36Resize(1920, 1080, dither="error_diffusion")

upscale = last

Interleave(source, upscale)

And here's what players say:

AVI/WAV File Source::Avisynth video #1

" G3" Video decoder is required to play the file.

Apparently the players don't support planar RGB. Convert back to interleaved RGB at the end of the script with ConvertToRGB().

Problem Solved! Thank you so much, jagabo.
