Does the "YUV -> RGB" parameter actually do anything?
Does it matter if it's PC scale or TV scale?

From distant memory, VFAPI, is some kind of frameserver thing, I believe that it can be used as input to TmpGenc (which I know you have experience of).

But it's not something that's automatically invoked as part of the normal VOB -> D2V -> AVS -> Premiere/vdub/tsunami/etc. workflow?

You could eg process something in VDub, and pass it on the TmpGenc without save to file.
Not sure why I ever used it with DGIndex, but I think I have done. Maybe it allowed you to directly read from a d2v file. (GOPS and stuff from d2v, video data directly from DGIndex though VFAPI memory pipe) Just found on my hard drive in a TmpGenc Non install directory of shortcuts, Installers. # README.TXT Code:
Need To Install READAVS.REG to use Avisynth & virtual dub frame serving Also good idea to install DIVX 5.x for YV12 decoding (otherwise need to convert to RGB24 for TMPGenc which slow it down a lot) and HUFFYUV for YUY2 #(REGEDIT4, seems to be from W2K, I think, is REGEDIT5 in XP) Code:
REGEDIT4 ; Replace the path below with the real path to the DLL. ; Be sure to type each backslash twice, as in the example. [HKEY_CURRENT_USER\Software\VFPlugin] "Avisynth"="C:\\NON-INSTALL\\TMPGEnc\\MyExtras\\ReadAVS.dll" Above Priority took some time to get in order, methinks (Also seem to be missing a good number). Page from TmpGenc site:- http://www.tmpgenc.net/en/e_vfapi.html Think there was a lot of stuff for TmpGenc VFAPI, much of it in Japanese:- https://www.google.co.uk/search?site...k1.n1uIziIzsgo Dont remember much else and dont really wanna go back there, way too ghetto

That sounds extremely useful for Vobsub/VSrip projects. But the bottom line is, can I safely ignore the YUV -> RGB parameter when using a VOB -> D2V -> AVS -> Premiere workflow?

If AVS output is usually OK (0>255 RGB, or 16-235 YUV), then see no reason why you would want input into AVS to be 16->235 RGB. However, can't speak for what Premiere wants, I dont not got it Why not just do a test and see if you get out what you were expecting.

By "ignore it", I mean "ignore it regardless of whatever it's currently at", not "be sure that it's always set to PC scale". This is an important distinction because I tried setting it to TV scale and setting Tsunami to YCbCr in an attempt to correct excessive lightening of black areas, which I later found out was actually a VLC problem, not an encoding problem... the point is, does this parameter actually do anything when using a VOB -> D2V -> AVS -> Vdub/Tsunami/Premiere/etc. workflow?
I don't know how many different ways I can phrase this question.

Okay, thank you.
EDIT: I guess this fellow asked the question that I should have asked: "how do I know if I'm using dgvfapi?"
