AddBorders and encode speed question, already, noticed, encode

andy

I mainly use tmpgenc, and have kinda a slow pc
and like to get all the edge on speed I can

My main question is what do you think about the need to add borders
I let tmpgenc center it for me, as it is already resized correctly
The reason I ask that I have noticed a speed increase
if I dont add borders

lets say the source is 2.35/1 16x9

1. add borders

Crop(0, 60, 0, -60)
BicubicResize(480, 272)
AddBorders( 0, 104, 0, 104)

2. dont add borders

Crop(0, 60, 0, -60)
BicubicResize(480, 272)

choice 2 is always faster for me, and I can only attribute it to not using addborders
in either case the borders are black as black

I guess Im just confused as to how much a difference in speed it makes for me
I am aware about adding borders before any filters or after filters and the effect on speed it would have

current software tmpgenc 2.512 and avs 2.08

Addborders is a quite simple operation. However there is less data to transport to tmpgenc, when you don't add them in AviSynth, but let tmpgenc do it. Also, if there is a colorspace conversion from AviSynth-gt; TMPGEnc, it'll be a lot faster.

Crop(0, 60, 0, -60)
BicubicResize(480, 272)
ConvertToRGB24()
Addborders(0, 104, 0, 104)

Might be faster, since TMPGEnc only reads RGB24 material. It might however still be faster to let TMPGEnc add the borders. Just do, whatever is fastest.
