  • Multiple Exports from Premiere Using Media Encoder

    For my wife's videography business, we constantly found ourselves exporting multiple versions of files at different times. We would edit a version with a logo watermark for the web and then have to go back later and re-edit when it came time to send out DVDs and also save a master without watermarks. After a bit of experimentation, we finally figured out a simple way to generate all the delivery formats we need the first time.

  • Adapting Old Pentax Lenses to Canon DSLRs for Video

    As soon as you get an entry level DSLR, you are immediately attracted by all the lenses you can't afford.  A great way build a diverse set of lenses for a very small amount of money is to adapt old manual focus lenses.  Manual focus and manual aperture is great for video and useful for photography too if you don't mind taking the extra time.

    For documentary style videos, audio is one of the most important aspects to tell your story.  Unfortunately, the cheapest way to get great images, DSLRs, also have the worst options for audio.  However, with a little preparation and not a lot of money, it is possible to get good sound in a variety of documentary shooting situations.

    Ever wish you could video chat with your dog during the day, and remotely feed them treats? Probably not, but now you can with just an old laptop, an arduino and entirely too much time on your hands!

  • Raw Video on Canon EOS-M using Magic Lantern
    Dec. 16, 2013, 5:41 a.m.

    After getting an EOS-M, my first step was to put the latest Magic Lantern alpha on it to get the audio meters and exposure tools (zebras, rec picture style) that I'm used to on other Canon DSLRs with ML.  A cool feature of the EOS-M though, is a faster SD card write (up to 40 MB/s) so that raw video is possible up to 1280x720. A pretty good guide to raw on the eos-m already exists (http://www.magiclantern.fm/forum/index.php?topic=8825.0), but I'd just like to put my workflow and experiences here. Camera settings: I use video mode, with crop mode turned on.  This gives about a 3x zoom, but gets rid of moire and aliasing.

    Shooting 720 further crops the image, so I recommend using a tripod and wide lens (the built in 22mm turns into 100mm or so).  Make sure to turn on global draw for RAW so that ML will draw a box showing you the framing for your raw crop. Post Workflow: I start by running all the files through the focus pixel fixer from the guide above since eos-m and t4i have focus pixels that need to be interpolated around.

    Then I run the new focus pixel corrected raw files through raw2cdng (http://www.phreekz.de/wordpress/2013/06/magiclantern-raw2cdng-cinema-dng/) with partymode on and set to around 1.1 gamma. This will generate Cinema DNG sequences that you can then import into Premiere Pro CC directly by choosing import and selecting the first DNG in the sequence.  The new direct link to speedgrade lets you create your edit in Premiere with native DNG sequences and finish your grade in SG with no transcoding.  The raw files do seem to have more dynamic range and highlight recovery compared to h264, but I'm not sure if Adobe is completely handling the cDNGs properly.

    Caveats: 100% clipped highlights show as magenta in premiere, but not in adobe camera raw.  The only workaround I have found is not to clip anything.  More things should be automated by scripts, the focus pixel fixer and importing cDNGs in premiere is all one at a time and a pain.  File sizes are huge (8GB for a couple minutes of footage around the house).  Files occasionally have a frame or two out of order (this may just be due to not having a fast enough card).
