Handbrake Help: Decomb & Export

I've been revisiting an old interlaced project and trying out Handbrake's decomb filter. Using decomb alone seems to give a really pleasing result. I think I'm finding it superior to every other deinterlace method I've tried--at least for this particular footage.

For some reason, however, I can't export lossless using the "Constant RF 0" setting. This seems broken in Win 7. It's actually giving smaller file sizes than RF20 (default).

So two questions: anyone else out there find decomb gives the best deinterlace result (at least) some of the time?

And any ideas for exporting an intermediate from Handbrake? Hopefully close enough to lossless to not give away the advantages of the decomb filter.

You can export lossless x264 encodes at RF=0 starting with Normal preset in Handbrake, but not High profile (the two will not co-exist by definition).
You can force I-frame encodes by putting :keyint=1 in the custom string.
You can combine the two, but it makes for ridiculously large files, with no added benefit that I can tell.

I have found optimal intermediate file size, near-lossless encoding, and "reasonably" robust timeline handling in Vegas using Baseline profile, RF=1, and keyint=1. Experiment.

The place to post further questions of this nature is the Handbrake support forums, which will garner you a wider variety of responses, and likely a response from one of their Developers.

True, but I know you're always prowling around here... :)

Have you played around with decomb? It really does seem to give outstanding results.

Use it all the time.
