First off, I’ve written a few time now about my trials and tribulations with audio to accompany my videos and pointed out some things that have worked and other things that have not. As I’ve mentioned previously, you can have a somewhat crappy movie with great audio and it’ll be watchable, but a great movie with crappy audio is completely unwatchable. If you’ve ever come across a YouTube video where the sound quality is just awful, you’ll know what I mean. We’ve watched many an old movie that’s been copied and put up on YouTube where the image quality isn’t the greatest, but the movie has been watchable because the audio has been reasonably decent; you can understand what’s being spoken and the music is fine. Quite the opposite to some others that get switched off in seconds. Audio has such an impact on movies and video in general that it’s one area where you have to get it right as there’s little room for error.
In an earlier story about the ongoing development of my cinema rig, I posted a video where I used green screen technique to introduce a background to what would have otherwise been a bland setting (with Winter afoot, nothing outside is looking that great). This ‘green screen’ technique is as old as the hills, but previously has been less than accessible to most people with a video camera. The green screen material has certainly been readily available, but the video processing software has not been quite so easy to come by and, where available, has often been expensive. But with new software options and especially software such as Blackmagic Design DaVinci Resolve, it’s pretty much available to anyone who wants to experience this frequently used Hollywood technique. And frequently used is an understatement, as just about every film made nowadays involves some or a lot of green screen technique.
The more video I do (or practice), the more audio comes into play and problems need to be resolved. I’ve already spoken about the issue with low audio volume when using external microphones (mics) with the BMPCC4K and the way I went about trying to get better audio. But the issues didn’t end there, I was now becoming frustrated when using Lav mics and recording to an external recorder, whether the Olympus or the El-Cheapo. The major problem was forgetting to turn on either the external audio recorder, start the audio recording or synchronise the audio with the clicker, or forgetting to do all three. So as I read more articles and watched more videos about wireless mics, especially Lavalier (Lav) mics, it became clear that I would be better of with a wireless mic where the receiver could connect directly to the camera audio input. This meant no synchronising in the video editor, saving time and the need for separate (and expensive) audio synchronising tools.
Again, the more things change the more they seem to stay the same, sort of. As I get to use and practice with the BMPCC4K and the rig, there are small and not so small issues that arise and which need to be addressed. One thing that I’ve been waiting impatiently for is for someone to produce a small and affordable Electronic Viewfinder (EVF). But, sadly, no one has yet taken up the challenge and so the only option was to get a larger and brighter field monitor. And, as I started to use more lenses with the camera, I found that changing the position of the follow focus and matte box introduced its own problems, so more things to remedy. Additionally, I really wanted to have a slider with me when I went on our bush trips, but the 120cm one I had was simply too cumbersome to take along, so that issue also needed to be addressed. While some of these appeared to be minor issues, some ended up being quite annoying in the long run.
There’s long been an saying that goes along the lines of ‘you get what you pay for’, or another similar saying being ‘buy cheap, buy twice’. Such sayings (like most sayings) generally come from practical experience and of course many others abound. But the gist of such sayings has generally held true over the years; however, is that always the case? I think much depends on the products concerned, who makes them and where they are made, especially in today’s world where it’s possible to manufacture and buy from just about anywhere. Product quality has also changed dramatically with new technology, materials and manufacturing processes, sometimes for the better and sometimes not. So the quality of a product often belies the past conventions of where they are made. Recently I had an interesting discussion, though not for the first time, about this subject and it made me look a bit deeper into how much this applies in today’s world where it’s not always fair to assume that ‘you get what you pay for’.
No surprises that there’s now a Part 10 to this ongoing story as I keep modifying and improving things with my camera rig. That’s most likely never going to end, but I’m close to having things sorted out as best I can. Anyone that’s been reading this blog and the stories about the BMPCC4K, will know that I’ve not been overly happy with the audio of the BMPCC4K. This especially relates to the 3.5mm audio input where, without several additional bits of gear, the audio recording levels of the camera have been virtually non-existent. So to fix this I’ve been using an Olympus LS-14 audio recorder, coupled with a Cayin C5 preamplifier, to boost the signal strength to something respectable. It works, but requires a bunch of cabling, battery management as well as remembering to turn on multiple devices. But all of that has come to an end, as I’ve found a much better solution in the most unexpected of places.
There seems to be a never ending progression of change when it comes to my camera rig, but given the flexibility with the way that the rig is assembled, it’s not too difficult to move things around. It’s a bit like moving into a new home and working out how the furniture best fits for daily use, and what looked OK at the beginning, a few days or weeks later proves to be a poor choice and changes follow. That’s pretty much what’s been happening with my camera rig, especially as I get more hours of use under the belt. Video is so far removed from stills photography, where the camera setup really doesn’t change at all over its life unless you consider swapping lenses a change. So once again I’ll go over a few additions/changes that I’ve made to the camera rig which may or may not be subject to further change.
One thing that I’ve come across on numerous forums regarding the BMPCC4K are questions about ways to effectively power the camera and get more recording time than what’s available from the standard battery. There are two regular ways to provide power to the camera, apart from using the internal battery option, and the first is by using a dummy battery connected to an external power source and the second is by using the camera’s external power connector to an external power source. It’s the external power source that seems to cause the most issues and raises the most questions regarding what external power source to use, given that many want to power accessories and not just the camera. The power requirements can be quite high if using a field monitor, external SSD, audio recorder and microphone all of which will tax a battery’s capacity.
Finally I’m having some success. As I pointed out in Part 6, as a last desperate measure I’d ordered an inexpensive powered Saramonic SR-M3 directional microphone (shotgun mic) to see if that would alleviate my need for the Olympus LS-14 audio recorder. It arrived and I have to say that I was apprehensive given that there was so little information available with regards to this microphone when it came to use with the BMPCC4K. Actually, I couldn’t find anything informative. Every review was about it’s use with a DSLR or mirrorless camera for vlogging purposes, something that wasn’t going to be its intended use. I wanted to use it as a field microphone for general use on my rig, which may not have been ideal, but that’s what I needed. As an aside, for once a product was available locally at considerably cheaper price than anything available overseas. I never cease to wonder at these price variations. There are plenty of general reviews of the Saramonic, so I’m not going to do a general review but will go straight into testing
No sooner had I thought that Part 5 was the finale, I made a few more adjustments and modifications that I thought would be beneficial to describe and record. It’s possible that this could go on for some time as things change and as I get used to using the camera rig and finding better ways to do things. I guess that’s the benefit of a camera rig that can be modified to suit one’s needs, but it’s also a double edged sward as you get tempted to modify things perhaps too much at times. Though I must admit, the changes that I’ve made have been for the better, especially as far as handling goes, and that’s the important thing over anything else. Mind you, I haven’t made that many changes to the overall structure of the rig, so it’s not like I’m moving the furniture around hoping for a better arrangement to arise. Continue reading
