Re: [Avid-L2] Practical Solution to Hulu Rejection of random Cadence?

Hey John

Happy to do the Teranex to 23.98 if you want to see what it will look like.

Most of the material is DVCProHD shot at 23.976 and their is some Canon 5D file based at 23.976. We also have some archival footage that varies between 23.976 and 59.94. 23.976 file material was ama'd in a 23.976 project and transcoded to 14:1 for offline. The DVCProHD tapes were ingested at 29.97 with the Panny 1200 and 1400 decks set to add pulldown. Hence the inconsistent cadences etc...

My understanding from a Teranex rep a few years back at NAB was that the Teranex can handle inconstant pulldown in real time. Given most of the show is 23.976 with pulldown added would it make sense to run the show through a Teranex or other hardware and have it remove pulldown on the fly to create a new 23.976 progressive master? This is the only practical solution I can see. Had I been involved at the beginning of the project I would have kept everything at 23.976.

I'm surprised Hulu didn't make a suggestion as to how to convert the master as I'm sure they see these kind of issues all the time. Is there a completely file based solution for these type of conversions. I remember Cinema Tools could remove pulldown on files but it had to be a consistent cadence, does an Alchemist or other converters handle file to file pulldown removal like a tape to tape dub would accomplish?

Seems to me like Hulu should be set up to handle these issues on their end but I guess they don't want to be bothered or incur the expense.
