Working with horizontal bar rig
Rig is not made to do adjustments during shooting, two cameras are placed high on horizontal bar and photo tripod - unstable thing
If you touch it or adjust one camera - footage on both cameras will be usually unusable at this period
If you absolutely need to change one camera framing, do it fast, preferable with one motion, hold bar or other camera head handle during this. Choose moment for this wiely, better do it during stop or pause.
Set cameras lens level at the eye level of representative you are interviewing
Tele camera framing, especially in 4K mode, usually includes face of representative and item he tells about
If item is large monitor or software or placed low on table - framing will be different
In case of software and 2 cameras on bar - tele camera is shooting computer screen
In case of low or large (large monitor or such) object it is B rolll that is used to show it properly
Most freqently interviewer is absent in second camera frame (except hand with microphone)
Make sure to keep proper angles, remember that representative and item he talks about are main objects of attention
Panasonic Cameras Settings
Make sure to reset all settings first.
GH4/GH5 Settings
Continuous AF: Off
Metering Mode: Center Weighted
Mic Level Display: On
Mic Level Adjust: -12dB (adjust to one that is more or less ok)
Direct Focus Area: On
Peaking: On; Detect level: Low, Display Color: Orange
Histogram: On
Zebra Pattern: Zebra 1 (use Zebra 1 or 2 depending on situation), set to
Zebra 1: 70% — target proper exposure for caucasian skin tones - usually this is main face exposition target for interview!
Zebra 2: 100% — target overexposed/clipping highlights, make sure to check it during any screen recordings, screen must not have overblown parts.
Constant Preview: On
Exposure Meter: Off
Video-Priority Display: On
Menu/Motion Picture/Page 1/Photo Style - set to Natural
Turn on 3:2 grid
Use manual WB (can check WB and colors, including matching between cameras using vectorscope on GH5).
If you want or forced to use auto WB, frame cameras same first, so it'll be almost no difference, and fix balance(!). WB must not change during shot.
Make sure that exposure is manual or locked before recording starts
Make sure that AF won't ruin interview after recording starts, fix it, switch to manual
Always use peaking and after this use focus assist (zoom) to check focus
Remember that interview does not require any fancy OOF, quite reverse!
Do not hurry, unfocused or wrongly exposed video has no use
Audio - Tascam DR-10X recorder settings
48Khz 24bit, mono
Mid level setting (MIC GAIN - MID, in very loud noise area, like loud music around, can change it to LOW, but change it back after it; normally we keep it fixed at MID)
dual level recording (DUAL REC MODE) - ON (very important! check! I won't be able to fix clipped audio without it!)
-
Always use new batteries at the start of the day!
Do not hurry, make sure to turn audio recorder before you starting cameras, and double check that recording started (issues happen due to slightly weird method to turn recording on)
Switch it off also as last item
Do not hurry, again. Lack of audio can't be fixed!
B Roll
Do not try to do fancy stuff like slides, zooms and such, at least until you did all else already
Make sure to make at least 15 second steady video parts for each important product feature
If in interview they tell you about some ports on back - show closup of the ports (>=15 seconds) and so on
Idea is to show close all product parts and actions (can be menus or such) they told during interview, it is like 3rd camera
Always keep enough timing for each part, do not rush
Sometimes it is required to also record audi using same mikeo, if it is long demo, for example, such will be inserted in the middle of interview
You need to do at least two big product shots (>=15 sec), for thumbnail and for interview entry
Try to keep product in well lit place and with contrast background (without water bottles and dumps
)
Make steady booth shot (>=15 sec), remember - no people you talk to or even left microphone can be in this frame
Always make 15 seconds B roll of their their badge and another 15 seconds with product card or product name, it saves lot of time durind editing
Try to keep white balance and properly expose shots
Always try to focus before hitting record, it saves your and editor time
Interview intro and ending
Intro
Before starting intro, put mike into working position near mouth, look at camera and count to 4 inside. It helps me a lot later in editing.
We are at XXX booth talking with [First_name_only] about YYY that [has some cool feature]. [First_name_only], can you tell us [more about it]?
Note that it is short, does not contain exhibition name, does not contain year, your name, anything you can forget or that can be just adding length. I'll add all this in titles or it'll be clear from context.
Such words as “Uhh”, “Umm”, “Aaa”, “Again”, “Hello” are prohibited
Ending
[First_name_only], thanks for showing us such wonderful product. {Look at wide camera}. Make sure to subscribe to Personal View channel to see more great videos and remember to click on little bell to get notices. See you soon!
After ending keep exact same pose and look into camera not lowering microphone, sor same 3-4 seconds.
