CHFD codec confusion at DVinfo.net

I'm running Premiere CS3 v3.2.0 with ProspectHD 3.4.6.

Today i needed to convert some digital camera video from 30.0fps to 29.97, so I did with speed conversion in Procoder. Within Procoder I had the following Cineform codec options: HD Encoder, HD Encoder2, HD codec V.3.8.2. None of those looked familiar so I punted and chose V.3.8.2.

The resulting file plays fine in Media Player Classic and Virtualdub, but is a blank green square when loaded into a Cineform project within Premiere.

So from within Virtualdub I resaved it as HD Codec 4.3.4 (which is the only codec that VDub sees) and that loads fine into Premiere.

So my questions are: whare these old codecs I'm seeing in Procoder, should I try to get rid of them (and if so how)? And is there a reason why Procoder can't see V.4.3.4, which seems to be the one I need to use?

CineForm HD Encoder (low memory) and CineForm HD Encoder-2 (highest performance) are DirectShow codecs. Anything with Vx.x.x. is a Video For Window version of the codec, there is some name caching happening so that you are seeing older version numbers, but they are likely the same version (as it is only stored in one place.) So I doubt you are using V3.8.2, if you open the codec settings the current version is shown.

This points to Procoder doing something wrong. Note: HDLink supports 30.0 to 29.97 conversion. If you want to do it the fastest way, using a AVI frame rate tool -- AVIFrate, to change the play speed in the header.

Great - that all makes sense, and I had completely forgotten HDLink did that conversion.

Thanks!
