ok the problem is bcoz of the grip filter.
the resln of the avi is 512x384
in tmpg without using any of grip lines in avs size is 512x384. the subtitles appear.
after using gripcrop frame size is 352x240. the picture is centered without the subtitles.
i did not use any templates for this test
here is the script i used:
ConvertToYV12()
BlindPP(cpu=4)
Blockbuster(method="noise",detail_min=1,detail_max =3,variance=0.1,seed=1)
Convolution3D(1, 6, 12, 6, 8, 2.8, 0)
Tweak(cont=1)
#GripCrop(352, 240, overscan=1, source_anamorphic=false)
#GripSize(resizer="LanczosResize")
Undot()
TemporalSoften(2,7,7,3,2)
DCTFilter(1,1,1,1,1,1,0.5,0)
#Blockbuster(method="noise",detail_min=1,detail_ma x=10,variance=0.3,seed=5623)
#GripBorders()
BTW should the gripcrop and gripsize not be used immediately after the avisource command.
the reason being once the image is cropped to the
right size the area to which the other filters are applied is reduced and therefore encoding is faster.
