    Hi All

    Wondering if I could ask about the Kona3 and its ability to convert captured files that are in various formats into on single aspect and format?

    I have clips from different 16:9 aspects with square pixels that I would like to letterbox into a 720X480, non-square pixel aspect. Could I make the Kona work for me in a situation like that?

    any suggestions would be helpful!

    Absolutely. That’s one of the things that the Kona 3 does well. It will down convert 1080 or 720 to letterbox SD, and it will cross convert anamorphic SD to letterbox.

    The caveat is that it has to come into the Kona over SDI.

    Post production is not an afterthought!

    What it and all other capture cards won’t do is capture differing frame rates…unless they are similar Hz. 59.94 and 29.97…similar. But you can’t capture 29.97 as 23.98 nor 25fps as 29.97. But you can convert any FORMAT to a uniform one.

    Meaning your files are sitting on a hard drive or your need to capture from tape to a file?

    Yes the files are all on a hard drive going to another hard drive through a Kona 3 or FS-1. Do I need to down step through plain old division? I am concerned since I have been told this one-step solution of putting through hardware will be a dirtier method…(more artifacts and potential issues)?

    Anyone done this before?

    You can pass video from one Kona to the next, but you can’t rakes existing files and convert them with the Kona on one computer.

    All your files need to be standard video editing codecs, in HD and sd. You can’t play out web deliverable codecs.

    Uncompressed, dv, dv50, dv100, ProRes, photo jpeg, avc-intra, hdv, xd cam, imx50, are a few examples of what will work.

    Wmv, H264 and Soreson3 are examples
    of formats that won’t.

    Hope it helps.
