  1. yeah, this happens every now and then: I start recording, then trying to stop recording but it just freezes. Have to do a battery pull. Happened in 96fps and 4k mode, haven't tried others. Can't really see a pattern...


  2. it sounds like you have a fair amount of control over your shooting environment. GH2 should be just fine but if you have the money, sure get the GH3. But GH3 is around $900-1000, for that you get GH2 and one of the nice SLR Magic CINE lenses..

     

    Lenses, a lot of people try to cover the spectrum of distances and apertures, and then maybe throw in a prime when they make an initial purchase, but I think it is a guaranteed way to end up with lenses you won't be using later.  So just start with one lens.  There are a ton of tricks to get any shot you want (with some minor compromise) if you have enough space to work with or in post.  And when you've developed your own style, you'll know exactly what lens you need to take your work to the next level.  And most likely it won't be any of the lenses you would have bought initially.

    Amen to this. Just buy a lens and start shooting, nobody else can tell you what you need. You will figure that out later yourself. If this is more of a hobby you wanna try out don't put too much money into it and buy too much stuff. You will get gear acquisition syndrome.

     

     

    What did I do? I started with GH2, made some test shoots for a few weeks and then the GH3 came. Bought that and used for around 2-3 months (really liked it). But I ended up selling it waiting for the BMPCC. Got really frustrated over delays and just started reusing my GH2 that was starting to collect dust. Bought a nice lens for the GH3 money and couldn't be more happier!


  3. Full official specs: http://www.olympus-europa.com/site/en/c/cameras/om_d_system_cameras/om_d/e_m1/e_m1_specifications.html

     

    At first I thought, fine, they just don't wanna add more programming cost to creating menu options with e.g a high bit rate mode.

    But looking at video specs it seems to already be two modes for 1080p, one "high" bitrate  24 Mbps and one lower 16Mbps..

    So it's just tweaking of numbers, this was a deliberate choice, what is going on here?!


  4. But I've yet to see Black Magic claim that the compressed RAW on the BMPC is lossless?  They were the ones calling it "visually lossless", and why would they qualify lossless, if it was indeed just lossless?

     

    http://en.wikipedia.org/wiki/Image_compression

     

    from the article.

     

    "The lossy compression that produces imperceptible differences may be called visually lossless."

     

    I'm willing to bet that you will lose a lot of flexibility in grading with this "compressed RAW".

     

    This is where I saw claims of it being lossless: http://www.blackmagicdesign.com/products/blackmagicpocketcinemacamera/techspecs

     

    lossless compressed CinemaDNG RAW

     

    But agreed, reading more from forums and seeing video reports is really confusing  :wacko:


  5. Please correct me if I'm wrong.

     

    If you record a format, then compress it, and it looks the exact same after playback, then it is "visually loss-less".

     

    If you record a format, then compress it, and you lose no information whatsoever (including detail that can't be seen upon native playback) then you have a true loss-less format. 

     

    It sounds like the compressed Raw is going to throw away some information.

     

    Lets not confuse things further with "visually lossless" and "true lossless" :)

     

    It's either lossless or lossy compression. And BM states that the PocketCC does lossless compressed CinemaDNG, that's all we need to know. Is anyone e.g debating wether an unzipped text file reaaaaally is the same as the original? No :)
