GH5 American shooting in the UK.

npm

Well-known member
Hey fellow GH users.

I am heading to the UK next week for a 3-week doco shoot. I am American and usually shoot in NTSC 24p, 60p, and then the VFR's like 120fps and 180/240fps with my GH5 and GH5S.

My question is, should I stick to NTSC and just tweak my shutter angle when I am shooting under lights? Or go all out and swap over to PAL and shoot 25p, 50p, etc.

Any help and/or real world experience would be GREATLY appreciated.

Thanks so much!

Stick with 23.98p but alter your shutter to 1/50th to compensate for the frequency. That's what I do here in mainland Europe as I prefer the look of 23.98p over 25p, and 23.98p gives me the most compatibility if I want to distribute globally as it's just a simple 4% speedup for PAL countries.

Super helpful, thanks Paul! I use shutter angle, is there a certain angle that will remove flicker from 50hz lights in all frame rates?

The shutter angle for 24p @1/50 is 172.8°, or technically 172.65° for 23.98p.

I don't know the GH5/GH5S well, but various cinema cameras can dial in an exact number, or at least have very common options.

Nice. Yes, the GH5 and S can dial in this number and also more with the synchro scan. This will work great for sit down interviews, but what about for higher frame rates?

For example at 60p, you would do 60/50 = 1.2 (x360) = 432. Doesn't seem like a possible shutter angle? Haha.
 
If you wanted to follow the 180° shutter for 60p, it would be 1/120. (The shutter angle is still 180° and only the shutter speed changes based on the framerate.)

If you were considering the frequencies and used 172.8°, it would be 1/125.

If you're using HFRs for slow-motion, it's best to experiment (which I'm sure you will). Personally, I shoot slow motion at 90° for less motion blur and even down to 45° for a certain look in music videos/sports/etc. Super-nice crisp images (99% in daylight).

Good tip. I'll have to see if the 172.8 degree shutter still works well in 60p under the 50hz lights. Thanks!
