Tried to search the www and here for this but couldn't really find any info regarding the 3 series A7 bodies.
Problem is the following: when I hit the record button on my A7RIII in 4k/100M mode, the Feelworld F570 external monitor via HDMI goes black. 4k HDMI output is set to 24fps as the F570 doesn't handle 60fps. I can see the HDMI output on the monitor until hitting record and can also play back 4k files and see them on the F570 but have no live picture during 4k recording.
1080p is fine at all fps levels.
I have tried:
- setting HDMI resolution to auto, 2160/1080p, 1080p and 1080i
- using different HDMI cables with different data transfer ratings
- 30p and 24p 60M modes
- changing gamma assist mode or turning it off
- going through the menu of the A7R3
- going through the menu of the F570 multiple times
with no success.
Sony manual claims the following by HDMI settings:
"* Images will not appear on the monitor of the camera if you record movies while the camera is connected to and HDMI device with file format set to XAVC S 4K" but actually the monitor of the camera displays what I'm recording HDMI doesn't.
I'm totally out of options here, anyone have any ideas?
I've been shooting a doc on the a7sii. WB is always set to manual, either incandescent or a kelvin setting. However, at times I'm noticing a strange "strobing" color shift in the footage and it's driving me crazy.
You can view a 4k sample here: https://bit.ly/2tO5dQh
The first clip in the above video is at 1600, the record player shot may be 3200. Picture Profile 7. High ISO NR was off I believe, but that should not kick in at 1600, right? It's mostly in the shadows and will switch back and forth a frame at a time ... but only sometimes.
Anyone experienced this before?
Here's a way to externally monitor while using touch focus!
Put the camera in 4K video mode. Save the setting to Memory recall 2. Plug in an external monitor. Start recording first. This does not work before recording. Touch the camera monitor screen (on the camera) to focus where you want. (must be in autofocus mode) This only works in 4K, video mode and you can see the focus brackets where it will focus, just not the image itself. That will be on the external monitor.
You can also set the focus speed and sensitivity to your liking in menu 2/1/9 and 2/2/9. Focus may "hunt" at the end of each touch without adequate light, so set to slow in 2/1/9.
I tried to attach small file-size SD version of a rack focus just now but the software says "Error You aren't permitted to upload this kind of file"
I found this hack after reading on the web that you can also see the video ISO setting when set to the same memory mode. (4K only) It will show what the ISO will be for the auto setting in video mode if you touch the AEL lock button before recording. This is handy to predict whether you're going to have too much noise in the shadows, especially if you're recording in a bright environment where you can't easily see the monitor. (I think 800 ISO is the minimum allowed for 4K)
What other hacks will MR2 do? Let me know what you find!
