Currently, if you specify two vbv parameters, --nal_hrd vbv is applied implicitly.


Here is patch snippet, implicit setting part for libx264.c.
+    /* Modify non-gui-supported parameters */
+    if (x4->params.rc.i_vbv_buffer_size && x4->params.rc.i_vbv_max_bitrate) {
+        x4->params.i_nal_hrd = X264_NAL_HRD_VBR;
+    }
+    if (x4->params.b_interlaced) {
+        x4->params.b_pic_struct = 1;
+    }
+    if (p && p->BD_TUNE) {
+        x4->params.i_nal_hrd = X264_NAL_HRD_VBR;
+        x4->params.b_pic_struct = 1;
+        x4->params.i_bframe_pyramid  = X264_B_PYRAMID_STRICT;
+        x4->params.i_slice_count = 4;
+        x4->params.i_open_gop = x4->params.i_open_gop ? X264_OPEN_GOP_BLURAY : X264_OPEN_GOP_NONE;
+    }

Great plugin! Thank you so much for all your hard work.

I am planning to use this for exporting from CS5 Premier on 10.7.2. However, I am a bit confused by some of the setting descriptions in the advanced section and the interaction between settings.

What I would like to do is replicate the following settings for Blu-ray encoding:

--bitrate 35000 --preset veryslow --tune film --bluray-compat --vbv-maxrate 40000 --vbv-bufsize 30000 --level 4.1 --keyint 24 --open-gop --slices 4 --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --sar 1:1 --pass 1 (or --pass 2) -o out.264 input.file

Would it be possible to add a text box that would override all the GUI settings and simply pass the parameters (like those above) directly to x264? This would be an extremely flexible option.
