Hi, Moreover, the filter expects the input upscaled with bicubic upscaling, so for other upscaling algorithms bad results are also possible. Also other models for x2, x3, x4 upsampling can be specified using following command: ffmpeg -i input -vf scale=iw*factor:-1,srcnn=path_to_model Configuration files with other models can be found here: https://drive.google.com/drive/folders/1-M9azWTtZ4egf8ndRU7Y_tiGP6QtN-Fp?usp=sharing _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
