Can you view raw footage on a monitor? What’s baked into the image by Log recording? What’s the advantage of having uncompressed footage vs compressed footage? With more and more cameras offering a variety of outputs and formats, it’s easy to lose track of just what you’re getting with each option and what they ultimately mean for the final image. Well, lucky for us, there are folks like Andy Shipsides at AbelCine looking to clarify and explain the differences, as he does in this very informative breakdown for HDVideoPro.
By now many of you may be familiar with the Blackmagic Cinema Camera – it made a splash at this year’s NAB show in Las Vegas. There wasn’t a person I talked to that wasn’t excited to know more about this tiny little RAW-shooting 1080p camera. Thankfully, the camera shoots more than RAW video, as it can also shoot slightly compressed DNxHD and ProRes — but what if you do want to shoot RAW? Just like with DSLRs, most of the RAW video available in higher-end cameras is slightly compressed, as bitrates can exceed bandwidth. To keep costs down, the RAW in the BMCC is completely uncompressed RAW video, which means, you’re getting bit for bit everything that is coming out of the A/D convertor (which takes the information from the sensor and translates it into digital values). We’ve talked a bit about increased disk space requirements, but rarely about affordability. The trend for most technology is to get cheaper over the long term — but that’s not exactly happening with hard drives for a number of reasons. More »
I’m still trying to catch my breath from this year’s NAB show, but all this week I’ll be posting more videos and a few more thoughts on what I saw there. This had been dubbed the year of 4K by many, but I’m not so sure we can call it that. 4K is still a couple more years from becoming mainstream, but there’s no doubt that manufacturers are pushing their televisions and cameras into the world of 4K2K and QuadHD. Even though there were a few devices capable of shooting in that frame size announced at NAB, none of them are currently shipping (though the FS700 is the closest – even though it won’t technically be shipping as a 4K camera). It was a big year for announcements, but a few companies stood above the rest, while others missed the mark. More »
I had a chance to stop by Atomos, RedRock, ikan, Jag35, Zacuto and had some great conversations with the people there. I will have video updates from all of these companies and more as soon as I can get them uploaded (again hotel WiFi is brutal, I know I am not the only one suffering from this problem). NAB 2012 is flying by and there is enough happening at this show that if it ran for a month it would still be impossible to cover everything in-depth. On a side note, if you’re going to make an app for your show (the NAB 2012 app), why not promote it a little more? This is probably advice for anyone making an app for any type of event like this, but promote it like crazy – from posters to telling people about it when they register.
