    Best video format for import

    Hi, We're trying to translate our Avid multicam projects into a tricaster project. So we have Stinger Intro and Outro (music & graphics over title) and lower-thirds graphics (alpha channel needed) as well as background videos for use underneath keyed people. So when we import these assets we get varied results in terms of quality. We work on Macs, so all of our files are prores or DNxHD.

    What's the best file type to import into Tricaster? How get graphics in with alpha channel?

    Any help/comments greatly appreciated,

    thanks!

    Matt

    I would use the SpeedHQ codec which is free for both Mac and Windows. You download it form here http://new.tk/dl Look under 'codecs and utilities'. The SpeedHQ codec supports alpha channel if you use one that ends with a '4' (ie 4:2:2:4). SpeedHQ can be contained in either a Quicktime or AVI file.

    Kanep, Is there a way to adjust the configuration of the SPEEDHQ codec?, to get lower size files? I tried on Adobe Media Encoder, adjusting the quality but nothing happens.

    Every file encoded with Adobe Media Encoder, using SPEEDHQ at 4:2:2 is 600 Mbs for 1:30 minutes.


    Please help!

    The data rate is set for the SpeedHQ codec, its always VBR @ 100mbits/second. Adjusting quality or data rate settings in the encoding tool will have no effect. You can use other compression formats, just make sure you test your settings in TriCaster so you know it plays correctly.
