All-intra vs LongGOP

[Al74]

I use the Lumix GH5S, shooting in V-Log L (MOV) with the choice between 400 Mbps All-Intra and 150 Mbps LongGOP. I’m asking because, in theory, All-Intra should capture complex, unpredictable motion much better. Since LongGOP uses predictive compression and averaging across frames, it seems like it would struggle with random movement compared to All-Intra, which encodes every single frame individually.
