I'm going on vacation to Thailand soon and will be shooting a little video about our vacation. I will make the video with my phone (Huawei mate 10 pro), a Canon 1200D, GoPro Hero 4 and a DJI Mavic Mini. Now I wonder if there will be problems because of the format when I put the different videos together. Are there then cutouts that are bigger and then cutouts that seem smaller because they come from another device?
There are at most problems because of the content. Respect the customs and customs of the country.
So if you set all formats the same (on each device) then that should work. And the format is actually always just the resolution does not stop but that does not usually much if you have good equipment.
No, there's no format problem, because you know all formats or can be set.
