how to tell to AVISYNTH: adjust resolution if not 1920x1080?

[marcorocchini]

Hi cats

please consider this avisynth script-base

videofile0 = LWLibavVideoSource("c:\myfolder\C0060.MXF")
audiofile0 = LWLibavAudioSource("c:\myfolder\C0060.MXF")
file0 = audiodub(videofile0,audiofile0)

Now I would like apply a .IResize(1920,1080) like

videofile0 = LWLibavVideoSource("c:\myfolder\C0060.MXF").IResize(1920,1080)

only if the video resolution is different from 1920x1080

And also add a line so that is apply a .convertToYUY2() only if the colorspace is different from 4:2:2

How can I do? thanks

if/then

I'm pretty sure it was covered in one of your previous threads

Here is one way to do it: if width is < 1919, then apply iresize(1920,1080), otherwise return videofile0 . (or you can use something else , like height to be the determining factor, adjust as you see fit)

videofile0.width<1919 ? videofile0.IResize(1920,1080) : videofile0

For the YUY2 - You probably just want to use ConvertToYUY2(interlaced=true, matrix="rec709") . If file is already YUY2, it's a no-op (nothing is processed). You don't need any if/then or logic, avisynth already does this. I'm assuming all your files are interlaced (hence the interlaced=true switch)

One note: "<1919" would allow clips that are 1919 pixels wide through without resizing. You should use "<1920" or "<=1919" instead.

I would use "!= 1920" (ie, not equal) instead so that larger clips would get downsized, as well as smaller clips getting upsized.

Why use IResize if the clips aren't interlaced?

And do you really want to distort sources that aren't 16:9?

I think because historically the OP has dealt with lots of interlaced material.
