flickering lights


Recommended Posts

Hi everyone,


I will be shooting my brother's wedding this weekend  (there is a pro photographer who'll be taking picures so my job is of secondary importance and it's  basically to have some footage to turn into a music video). Anyway:), I have a question regarding the shutter speed. I do realize it should ideally be double fps, but I will be shooting at 30p and I know that the lights at the venue flicker at 60fps, so which would be the lesser evil: to increase my shutter to, say, 1/70 or decrease it to 1/50? Or maybe other values? How significantly would it affect the footage? Let's, for the sake of the argument, ignore the fact that I can shoot 24p. I'd appreciate any suggestions.

You always have to be aware of differing frequencies. For example: With the GH2 I could shoot 23,98 fps with 1/50 shutter speed in my (50 Hz) country (same for 25 fps). For most LED lights I had to change to 1/40. Some camcorders allow to fine tune the shutter speed, until flicker and wandering bars disappear (> Clear Scan).


With the BMPCC, it's still possible to shoot 30 fps in european countries, but you have to change the normal shutter angle from 180° to 216°.

      These lights, if you can afford them, look to be the Hot Setup!

      Hey fellas!
      Recently ditched my 5D3 for A7s. Mostly because of low light stuff but also for better slomo capabilities.
      Yesterday I tried 120p for the first time but I totally forgot about the flicker and WB was on auto so it doesn't went too well.
      Any tips on shooting extreme slomo indoors?

      I have a question about GH4.

      it can record 4k@25-29fps with an average of 70-90mbs according to my test, does it mean that 25fps mode has better quality than 29,97 ? Less frames so better quality per frame as it's the same data rate per second for the two settings ?

      Hello All - 
      this is a really basic question, so if there is a good/easy resource - can you please just send me the link and I will go and read etc?
      I have a new sony rx100 II. Yay!
      From user guide:
      When you create AVCHD discs from movies recorded in [60p 28M(PS)]/[50p 28M(PS)], [60i 24M(FX)]/[50i 24M(FX)] or [24p 24M(FX)]/[25p 24M(FX)], it will take time as the image quality must be converted. To save [60p 28M(PS)]/[50p 28M(PS)], [60i 24M(FX)]/[50i 24M(FX)] or [24p 24M(FX)]/[25p 24M(FX)]movies without converting the image quality, use Blu-ray discs. 
      In the record setting on the menu of the camera:
      60i 24M(FX)
      60i 17M(FH)
      60p 28M(PS)
      24p 24M(FX)
      24p 17M(FH)
      I understand (i think!) the basics of interlaced vs progressive...
      Background - at the moment, i am mainly shooting wierd little clips i see and family stuff - not yet into serious film/video making..
      So, some questions:
      - what do the above acronyms/nomenclature mean?
      - when would i shoot interlaced vs progressive?
      - when would I use the above settings over the other for any reason? Is there a setting I would just leave it on 95% of the time? Does the answer depend I guess on what media I want to put the video onto in the future? If it just stays on the computer and I stream/watch via say apple TV I guess that bit doesn't matter. 
      - at some point, I'll be back in Australia where PAL is used. Does this sway the answer at all?
      Or is it simply - shoot in 24p (one of them above - what is 24m vs 17m?) - and worry about it later??:)
      Thanks for any help/answers.
