All-intra vs LongGOP - Al74 - 09.07.2026 Hi All, I have a question: When shooting moving ocean water, light reflections on water, or low-light/night footage, should I use All-Intra or Long GOP? Best, Alek RE: All-intra vs LongGOP - Selur - 09.07.2026 It depends: if the format is lossless: it does not matter if the format is not and you compare it at the same bit rate, long gop potentially will keep more details unless you use really high bitrates (main point for all intra is that is can be easier cut) RE: All-intra vs LongGOP - Al74 - 09.07.2026 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. RE: All-intra vs LongGOP - Selur - 09.07.2026 Yes, with 400Mbps you should be near lossless, so naturally sudden changes should not cause issues. RE: All-intra vs LongGOP - Al74 - 09.07.2026 But 400mbs is for All Intra, LongGOP is 150. Hmm, so it seems that for fast, randomly moving objects like water particles, reflections, also noise at night which could be treated by LongGOP strangely, All intra is the way to go, I plan to record in 4K of course. |
