uiimageview - Fade in/out Image in UIIamgeView happens with no duration -

-

i have uiiamge created programmatically in viewdidload of detailviewcontroller. .transitioncrossdissolve between current image image. problem once detailviewcontroller displayed switch happens right away no matter duration. never see first image. using following code. 

    let rect = cgrect(x: 0, y: uiapplication.shared.statusbarframe.height, width: view.frame.size.width, height: view.frame.size.height / 3.0)     let imageview = uiimageview(frame: rect)     imageview.image = #imageliteral(resourcename: "head1")     imageview.contentmode = .scaleaspectfill     imageview.clipstobounds = true     view.addsubview(imageview)     uiview.transition(with: imageview,                       duration: 16.0,                       options: .transitioncrossdissolve,                       animations: { imageview.image = #imageliteral(resourcename: "head3") },                       completion: nil)

try start animation in viewdidappear delegate. think thats problem.

batch file - filebot superstrict script: need tiny video sample or other solution -

-
seeing how filebot can make massive mistakes (even in strict mode) when renaming videos created script make sure there's no mistakes , lets me check suspicious ones manually. it uses dummy 0-size copy of video in dedicated folder figure out new name renamed , doesn't tagged video , audio info since it's not real video. it simpler , more accurate have variable tags in place need tiny part of video (with tracks) instead of 0-size dummy. what's easy way this? all unknown variables see extrapolated video filename in other script, should not relevant here ask away if need be. @echo off /f "tokens=*" %%f in ("%full%") ( set "fullpath=%%~dpf" set "file=%%~nxf" ) :: prep fake temp file set tempdir=%temp%\%date:~3,2%%date:~6,2%%date:~11,2%%time:~1,1%%time:~3,2%%time:~6,2% mkdir "%tempdir%" && copy /y nul "%tempdir%\%file%" >nul :: filebot string (to shorten lines) if "%type%"...
