This part will focus on post production, usual step for any kind of video work you would like to present to your audience.
The very first bit of the whole chain is to have all your clips matched in terms of luminance. In the IRE scale the blackest point has to be set to 0, while the whitest to 100.
This way you know that anything below 0 will be totally black and anything above 100 will be pure white; both 0 and 100 are the threshold to get any detail in your picture. You have to do this work for all the cuts in your final editing, plus balancing out the RGB channels. It’s quite a tedious work, but once it’s done, you’ll know that the whole piece will be like one.
The next step would be to fix any issues, like under or over exposed areas of your footage… hopefully you will not have to deal with it, but chances are that it might happen if you are shooting solo or on a very small production. Especially doing exteriors, it’s difficult to control the action and the tech part as well. Never mind if you are shooting manual as well, we film-makers mostly do.
One of the great things about the micro four thirds format is that you can simply mount anything on these. It’s just a matter of finding the right adapter, among the variety of available offers. In this particular case, the C-mount to M43 one pictured above is indeed well made, but there are cheaper ones starting from just a few bucks.. Fotodiox comes to mind.
C-mount lenses are still in use, no longer as 8mm or 16mm cinema lenses as they used to be but as security devices lenses, namely closed circuit television lenses. Normally they are pretty fast lenses as they need to work 24h and they come under the commercial term of TV lenses (from the CCTV acronym).
This is why some may be interested in the vintage C-mounts on a cropped sensor. Fast glass is expensive and C-mounts are not.
You have certainly noticed that I mostly write about the GH2. I used to own the 5DmkII, it was the first DSLR I shot video with. It has indeed been the first love for many and still truly is. But since the coming of the hack for the panny it was sudden divorce for me.
I still love the colors you get out of the Canon, there is a certain richness and overall dynamic range you simply cannot get out of the GH2. I feel that the whole color pattern has a grey, duller base throughout the gamma, with a green bias.
You have to work hard around this in post to make it look great, but it’ s doable. I have an upcoming post dedicated to color correction and I will discuss this matter in greater depth soon. The way your final work looks it’s too much of an important subject to be done with a few lines.
While there is no doubt the above sticks as a con, 0n the pro side
– the panny it’ s true 1080p as opposed to the lower resolution of the Canon, that claims to be full HD but looks like HD ready (720p)
– magic lantern it’s a very nice addition, but even in its latest incarnation cannot deliver as much as Vitaliy Kiselev and all his community have so far achieved with Ptools and the patches
– it’ s got a swiveling screen in place of a non sens fixed lcd
– it’ s way cheaper
