Need help whit encoding (Interframe parameters)

[Selur]

Like this?

Smooth: {rate:{num:12,den:5},algo:13,gpuid:0,mask:{area:0},scene:{mode:3}

your are missing a '}' at the end

{rate:{num:12,den:5},algo:13,gpuid:0,mask:{area:0},scene:{mode:3}}

a bit more readable:

{
  rate:
  {
    num: 12,
    den: 5
  },
  algo: 13,
  gpuid: 0,
  mask:
  {
    area: 0
  },
  scene:
  {
    mode:3
  }
}

also the guid parameter is probably wrong:

    gpuid: 0,

Defines which video card should be used for rendering, only works with GPU rendering enabled:

    0 - default (use 1st available GPU),
    11 - use 1st GPU device on 1st OpenCL platfrom,
    12 - use 2nd GPU device on 1st OpenCL platfrom,
    21 - use 1st GPU device on 2nd OpenCL platfrom an so on.

since 0 is already the default and you probably need 12 or 22.
(got no second gpu, so I can't test it here)

You think using the gpu for frame rendering speed things up. Or is just lame?

it might, especially if you cpu isn't that fast and already reaches 90%+ when just using the encoder.
