ML RAW video: 50D camera test
« on: June 23, 2016, 04:27:06 PM »
I finally edited some shots I made during summertime in the harbour at Weymouth (Dorset, UK) in 2013, using my Canon 50D and an old version of ML -- better late than never, I suppose! Shot with just the standard Canon kit zoom, it was my first serious test shooting with ML RAW and I recorded wild audio for some atmosphere sound. Post production workflow was: import DNG sequences into After Effects to export small proxy files (H.264 MOVs) for the off-line edit in Premiere. Then reproduce the edit in After Effects for the on-line, which includes final colour work (invoking ACR) and enlargement to 1080p25 for the export.

Almost any camera can pull off a decent close-up of something, so although it's a bit boring, I shot mostly wide views on a tripod featuring lots of detail to see how well it was resolved. It was a warm day and as expected the 50D got very hot. On a few occasions when I wasn't noticing the temperature warning turning orange, some takes were automatically terminated because the camera was forced to shut down -- sometimes the top of the pentaprism was actually too hot to touch. But turning the camera off frequently after a few takes was a reasonable working method for heat management and using a battery grip probably helped too.

It's not a short film but a camera test - the leisurely editing style is purely to give a bit of time to see the RAW image character, though it's a shame something of the sheer luxury of the RAW look does not fully survive my H.264 export followed by youtube's own secondary encoding. But I do like the character of these older Canon cameras with RAW shooting: almost incandescent colours are available in the files yet skin tones remain very natural. And the fact that the 50D can't normally shoot video at all makes it strangely rewarding.
