Using HDMI & USB


Recommended Posts

Hi, I have a question about using HDMI output and USB camera control at the same time, Is this possible ? we have two A7RM2 cameras, and we use the HDMI output to stream video to Black Magic recorders, but we need to be able to use " Remote Camera Control " via USB to take photos and change camera settings remotely, as we cannot access the cameras to make changes manually while recording. can these two functions run simultaneously ? It seems crazy that you cant use USB to remotely take photos while using the HDMI output to get a picture on a remote display.

 

Thanks, Angus

You haven't plugged things together & tried it? I use the HDMI output to run a monitor (not a recorder) and have a remote connected via USB port and both operate simultaneously without issue (A7sII). Don't know why a hooking a recorder would be any different. (Are you by chance referring to the Play Memories Remote Control camera app?)

We have had things plugged in and tried different setups, we are basically using the HDMI out to monitor the picture for setup, but with the Black magic we can also record what  the camera see's, the trouble is, as soon as we plug the USB into a computer ( Mac mini's ) we loose the picture from the HDMI. We're using the Sony software called " Remote camera control " which is a free download from the Sony website. is there something in the camera settings we have missed? the instructions aren't at all clear on this.

I've used the remote app with my phone but never through the computer when it's tethered which sounds like your setup. I'll rig mine up similarly on Wednesday. Check your USB connection settings for the camera. If that computer based app is capable of controlling the camera I suspect the USB page on the camera isn't set correctly. The phone app remote works well for changing settings but there's a slight lag if you're panning or correcting framing with it. And, yes, the Sony instructions are ABSOLUTELY WORTHLESS.

    • I mostly see posterization artifacts, which are the result of lossy compressed RAW files (or bad jpeg conversion). Unfortunately, the A6400 doesn't offer uncompressed or lossless compressed RAW. The noise might indeed result from the smaller sensor than what you're used to. If you're not shooting at max aperture, you could try shooting at wider aperture and lower ISO. When you're not shooting at max aperture, fullframe versus APS-C shouldn't matter much in terms of ISO-performance combined with depth of field: at the same ISO and aperture value, fullframe offers better noise performance but with a narrower depth of field. This can be offset by choosing a larger aperture and lower ISO on the APS-C camera. If you want a fullframe camera the size of an A6400, try the A7C(ii).
    • ..unfortunately, the lighting was correct. The shot required deeper shadows. The K1 ff didnt have these banding issues [yes, I know the sensor is larger]. The film shots had details in the same light. The sony files, both the jpg and raw, had this banding/noise - with NO retouch or post adjustments [straight out of the camera]. the camera was purchased new a few years ago and I am trying to determine if there is something wrong, or the settings are wrong, or the camera just cant handle this kind of lighting [studio + softbox]. No shadow detail is one thing... banding/noise in the shadows is unacceptable. Does sony have a body this size that is FF ? Im wondering if that would make a difference..  dw
    • The root causes for banding are uneven lighting, incorrect exposure settings, or compression artefacts or certain kinds of artificial lighting, especially LED lights. Also the lens used plays a role, I have noticed it more with my sharpest lenses, looks like they outresolve the sensor when I have a uniform blue sky. There is more than one solution, and ultimately post-processing, but the root cause has to be identified first.
