Some of the Sony bodies allow 1/4 shutter speed video which allows videos of the milky way by dropping the refresh rate extremely low. Is there any way to do this on a z9? Aware of starlight view but that is more for composing stills.

Yes, setting g10 "Extended Shutter Speeds" if turned on allows slower shutter speeds down to 1/4 of a second at any frame rate up to 60p in manual mode. It seems that 100p or 120p limit you to 1/100 and 1/125, respectively.

This is excellent news. If you have your z9 and can test something else...the best way to get the best footage in starlight is to use 1/4s and drop the fps to 24. What is the highest iso in video it allows with those settings? If z8 has this I am going to be using it quite a bit.

There doesn't seem to be an ISO limit in NRAW, ProRes or H.265 10 bit at 24fps in 4K or in 8K resolutions...was able to set at 25600 in any mode.

Thanks. A shame that it cannot go into the high modes ala stills but can always boost in post I guess if needed. Maybe 1080 will allow it.

You can actually go into the high modes if you shoot in H.265 10-bit or ProRes HQ but not in NRAW or ProRes RAW. NRAW and ProRes Raw do not support a 1920x1080 format but H.265 and ProRes HQ do and also support all high ISO's at that resolution. It seems that where the extended "Hi" iso's are supported, that works for SDR, HLG and N-Log.
What file format/codec were you hoping to shoot?

The info you supply is great thanks. I usually output my video with a h264 codec but h265 will be fine to. With my drone, a mini 3 Pro it is usually shooting in high bitrate h264. It is good that the camera will then let me go to equivalent of iso hundred thousand ish in video in h265. Il
Nb I'm always amazed how small the video files are after putting them through premiere with the h264 codec vs the recorded files which are massive!
