Recording error - white blocks appearing on video

Recommended Posts

Hi. Anybody know how to stop this happening when recording on a Sony a7sii?

 

Shooting XAVC S 4K, 25P 60M, Shutter 1/50 

 

Every few minutes throughout the recording white blocks appear for over the image for one frame.

      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!

      I noticed that AF-C doesn't work well with the Rokinon 50mm AF lens on my Sony a7s i. The camera never stops hunting for the correct focus. I tried the lens on an a6000 and the AF-C worked really well (fast and accurate). I tested the lens on an a7s ii and I had the same issue. Finally, the lens worked perfectly on the a7r iii.

      Ive heard of people having similar issues when trying to use the Zeiss 55mm lens on the a7s i. I tested the Zeiss 35mm 1.8 lens on my a7s i and it focused perfectly.

      I realize the camera is outdated but has anyone had any similar issues / success solving the problem? My a7s i has firmware 3.20.

      Thanks!

      Hi all,
       
      I just received my new Sony a7 iii and I was so excited until I came across a problem I hope someone is able to help.
       
      I cannot seem to find the video settings for 120 frames on 1080p (I only have up to 100) and on 4k I can only choose 25 frames - no 60 frames is showing.
       
      From the YouTube videos I saw, everyone has a different list to choose compared to mine.
       
      I checked and I have the latest firmware available installed and my memory card (scandisk extreme pro) wouldn't be the problem.
       
      Has anyone came across this same issue or knows how to fix it?
       
      Thank you in advance.

      Hey,
      I'm upgrading from the A7s to the A7sii for the low budget commercial/short films that can't afford to rent.  This means I rarely do long takes.  Looking through the forums these camera's do have an overheating problem.  I do have a pretty decent kit from my A7s including a dummy battery to V-mount, cage, and Odyssey7Q+.   Though I rarely used my old A7s for 4k since I don't exactly trust HDMI, i've never had an overheating issue with it. 
       
      It seems like using external batteries, pulling the screen off the back, and the v3.0 firmware helps with cooling during 4k.  But it seems like most tests are on continues takes, not for multiple 1-5min takes.  Was wondering what peoples experiences are with non-continues 4k recordings, also if anyone uses a dummy battery does that appear to help with overheating.
       
      Best regards
