From the responses to the original post it appears that few members of this forum are that interested in video !
Personally I have only recently become very interested in video as an alternative to still photography as it is a new opportunity with the same old subject matter if you get what I'm saying. The R5 is a very capable piece of kit when it comes to video but it seems it isn't without it's problems, especially when it comes to overheating. Lots of long time shooters are dismissive of video and probably for a variety of reasons, not least not knowing how to handle it especially when it comes to post processing. After about 15 years of interest in still photography I'm still very much an amateur in every department, everything I know is mostly self taught and consequently video is a case of starting all over again and just watching a couple of YouTube clips has me confused already! So far I have limited my PP to iMovie which is relatively simple.I will continue to investigate other ways too!
The few things that I have picked up already are obvious ones but weren't before hand so if you are about to launch in to a trip of a lifetime you need to be aware of potential shortcomings before you set off.
Hand holding is very difficult, every movement is captured so a firm base. ie tripod, is a huge benefit.
If you intend having sound, get an external microphone. They do tend to be cumbersome though and if you are on the move not very practical.
Video swallows memory and eats battery power. The R5 easily overheats so keep your finger off the trigger until you have something worthwhile to capture. It's not easy when you are trying to anticipate action though. I found regular stopping and starting the clips when they had captured nothing meaningful a benefit in the field as it made it much easier to clear unwanted footage and frees up storage.
Shooting in 4K demands a huge amount of storage space, especially in slow motion, ie 120fps. I love the results though. You can also speed them back up to normal speed in PP.
Seems like a stupid tip but make sure you are actually recording when you hit that little red button. I have numerous clips of the camera waving about with nothing on it and at the same time having missed what I though I had been recording. It's easily done!
So that's my limited contribution but I welcome anything that might help me in the future so hopefully some more comments.
