Q3 shutter speed when shoot at 25fps

As I'm based in the UK, I've always shot 25fps for video on my Sony cameras, and set the shutter speed to 1/50th of a second.

As I'll be mixing Sony and Leica footage if I use it on video shoots, I assume I need all the cameras to be set to the same fps setting. However there is no 1/50th of a second setting on the Q3.

Does setting the shutter speed on the Q3 to 1/60th of a second when shooting at 25fps have a visible/detrimental effect? I've shot a test and it looks OK. But is it OK?!

how are the videos displayed? if its transmitted for broadcast then 25fps makes sense, if its going to playback from disk to a tv or on the internet then the frame rate doesnt make a difference

Yes that is totally fine. You'll never notice the difference between 50th and 60th of a second shutter at 25fps. It wont have a jarring effect like it would if you shot 25fps, but your video output was 24fps or 60fps, if that makes sense. Crucially you need the Output (final video) and input (camera) FPS to match, but the 180 degree shutter (fps being half the frame rate) rule isnt 'that' important. If your shutter is anywhere fro 40th to 120th it'll look fine. The further away the subject, the faster the shutter speed can be without noticing the slightly less smooth footage.
