    best quality export for ftp

     I am working on a project that requires me to ftp files to a graphic designer, for him to drop in gfx and return. My project is 25i Pal, my mxf media is ingested as 2:1. My question, what is the highest quality export codec/format I can use ?   I am using MC 5.

    thanks from a newbie

    Re: best quality export for ftp

    I usually get a lot of arguments with this one.  Lots of folks ask me for "uncompressed QuickTimes".  But often the originals were shot on crappy HDV cameras; or the final product is only being seen on facebook or YouTube.

    So 90-95%of the time, I just export a full QuickTime movie, Same As Source, Use Avid Codecs.  Then I tell the graphic designer to make sure he/she has the Avid codecs loaded.

    Plus by using Same As Source, you'll be amazed how fast the export happens.  An hour of HD "uncompressed" sometimes takes 2-4 hours.  With Same As Source it's more like 7-10 minutes.

    Re: best quality export for ftp

    Thanks for your reply, am i right in thinking to export the best you can't get better than QT full res, I have to maintain highest quality. Most footage was shot on Digi Beta and mini dv, the end result is one film going to dvd and many strands for phone apps. My worry was just not compressing it too much as the file travels to graphics and back. Not sure why I would need the alpha channel separate.

    Re: best quality export for ftp

    You're sort of right.  See, even "uncompressed" is technically compressed.  Apple ProRes, Avid DNxHD220x... these are all resolutions that keep imagery looking as stunning as possible -- meaning that there is no visible pixel junk on the screen.  But imagine what "uncompressed" meant to the editing world 15 years ago... and imagine what it'll mean 15 years from now.  We'll be using Avid DNxHD2175xx, and look back at 220x as crap.  Thus if the simple process of capturing places a compression on the footage, then of course you'll want to not inflict more compression on the export.

    But if that's the case then why not always export uncompressed?  Because there is a certain visual point where you can't discern the difference bwtween two compressions - yet one of them took 6 times as long to make and takes up a ton more space on your hard drive.

    So the quick answer (too late, I know) is to export in such a way that no compression is seen beyond the compression in your edit system... and hence, using Same As Source.

    Clear as mud?

    Yup I'd go with Pixel Monkey.

    There's no point in going for anything above the compression in your time line. 2:1

    Expandingt he data up to uncompressed doesn't add any quality. It just makes a bigger file.

    Arguably it may make compatability simpler but as you can download Avid codecs for mac or PC for free.

    Then you may as well do same as source.

    If they insist on uncompressed then suggest you also expand to 32 bit as well just to be sure it's as good as it can be.

    In fact why not go the whole hog and move up to 50 fps :-)
