de-interlace doesn't work here - you need inverse telecine/pulldown removal

Subject: [Avid-L2] Re: Practical Solution to Hulu Rejection of random Cadence?
What about a hardware pass that just deinterlaces the whole show. Sure there might be some occasional duplicate frames but it would alleviate any split frames and more or less stabilize the random cadence. I don't know how you fix everything at this stage with all the motion speed ramps etc...

First of all, that's utterly insane that it was rejected. Absolutely every filmed TV show done up until most of us started editing in native 24p was a 29.97 interlaced SD show with mixed cadence. The film was telecined with pulldown to transfer masters, from which the show was edited. Therefore, every one of these SD shows has inconsistent pulldown. There's nothing wrong with it if the master is intended to be 1080i or 525i.
Obviously network QC is what it is and they are probably concerned about compression for crappy streaming over the web. Hardware is your best and maybe only option. I believe Teranex will make the adjustments by converting back to 24 internally and then re-applying pulldown. I'm not sure how well it deals with a mix that might include actually 29.97i video content along with the 23.976+3:2. I'm also not sure how well this works with the newer BMD Teranex units. The last time I had to work with one of these was one of their Image Restore boxes back when they were their own company. This may cause some analogies at cuts.
Another way - if it is all 24p original from some source - is to fix it in Media Composer, but you will have to go shot-by-shot. This would get you back to 24fps and then generate an interlaced master with consistent cadence from there. Or just deliver 24p if they take that.
