Error in Resize after after Lower Res. - Dan64 - 18.10.2023 Hello Selur,    I found a resize problem under specific setting.    The input movie has resolution 1920x1080    Since I want apply RealESERGAN to speed up the resize I applied Filtering->Vapoursynth->Misc->Lower res. before resize = 2     After having applied all the reaming filter settings and save the job, it is displayed the following error     The problem is the following:        1)  the initial size is: 1920x1080        2)  after the crop of 130 up/down the size is: 1920x820        3) then after the resize by 2.0, the size is 960x410        4) Hybrid add a border of 2, so that the size becomes: 960x412        5) RealESERGAN resize the video to 3840x1648        6) then Hybrid resize the video to 1920x820        7) the Hybrid remove 8 pixels from the border        8) the final size is 1920x812 -> ERROR          I think the the step 7 should be applied before the step 6, in this way the output size should be correct        I hope that you will be able to fix this issue Thanks, Dan P.S. I attached the debug file RE: Error in Resize after after Lower Res. - Selur - 18.10.2023 Think I fixed this a few days ago.

Cu Selur RE: Error in Resize after after Lower Res. - Dan64 - 19.10.2023 Hello Selur,    The problem has been fixed with the last dev version.    It would be nice to add the option to resize using the mod (2,4,8,16,32) in  Filtering->Vapoursynth->Misc->Lower res. before resize so that the add/remove border will be not more necessary. Thanks, Dan RE: Error in Resize after after Lower Res. - Selur - 19.10.2023 The add/remove borders might still be necessary, i.e. if you resize to mod2, but the resizer requires mod16. Also, I would rather add and remove borders than resizing and by abiding by a specific mod change the aspect ratio. Only minimal change, but adding and removing borders is fast and should not change the aspect ratio. Cu Selur Ps.: I'll look at it, since it should be easy to implement. => correction, is unexpectedly complicated to do this while maintaining the aspect ratio (as good as possible). => after some thinking about it and some calculation, I think it's not really possible without further restrictions.
