Alpha Chanel ? transparency in video

[djmisterjon]

also check the avs script

Find the location where it's saved

Add ShowAlpha() , and save it with different name , like test.avs

LoadPlugin("C:\Users\jonle\APP Portable\StaxRip-x64-1.5.0.0\Apps\Plugins\avs\L-SMASH-Works\LSMASHSource.dll")
LSMASHVideoSource("C:\Users\jonle\Desktop\testFire01.mov")
BicubicResize(992, 192, 0, 0.5)
ShowAlpha()

open test.avs in vdub, do you see white/black alpha like in AE ?

it should look something like this when you view the alpha directly. If it does, there is nothing wrong with your avisynth install, or your lsmash version, and the problem is downstream, such as ffmpeg version, or libvpx version

I think I arrived at a result
thank a lot for you help my friend.
i try update all
i try some format here
http://avisynth.nl/index.php/Avisynthplus_color_formats

FFVideoSource("%source_file%", colorspace = "RGB32", \
              cachefile = "%source_temp_file%.ffindex")

RGB32 seem work
and i remove -pix_fmt yuva420p , i just dont use it at all!


But i have a strange repainting.
As if the engine kept an instance of each frame, but forgot to erases them.!
very strange

Almost looks like image stacked in overlay, not clearing or displaying per frame

Did you try with one of the videos I uploaded ?

Upload your current output video

I see you already posted on their issue tracker. The problem is on their end, since the video plays fine in browser (FF, chrome, not sure about others) with default HTML5. So just wait for their reply
