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.

  • 1080p29,97
  • MP4
  • 20Mbit

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


  • 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 :-)


  • [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.
