Is it always better to record the A7s via 8 bit UHD and downsample for HD delivery? Or is the in-camera scaling of the 4K sensor for HD, via the built in XAVC codec just as good?And what is the best exposure strategy for this camera too?Just so there’s a reason for reading the rest of this rather long post the answer IMHO is an emphatic yes. Click the image below to expand it and check XAVC on the left and a ‘properly’ exposed and post workflowed (if that is a verb) UHD version. Awesome isn’t it...

We’ve a bunch of exterior shoots coming up and i’ve been seriously considering the A7s over the FS700 because if it’s size and the fact that it can be rigged and gimballed easily. Last article we looked at issues of resolution and increasing colour depth by downsampling. We know that approach works well.Overall the dynamic range of the A7s appears to be roughly the same as the FS700, around 10 to 11 stops. (And if you read the rest of this blog you’ll know that i believe camera manufacturers ove...

The new firmware v3 for the FS700 gave us 4K RAW but it also gives the standard camera some new curves to record with, these are SLog2 and 800%REC709. Sonys reason for adding them is primarily to help with monitoring RAW recording on the LCD, the SLog2 adds a massive amount of detail in the highlights which gets around how to monitor the large dynamic range of RAW on the internal LCD.Of course you can record with these curves with the stock FS700 and they offer some useful options. The biggest p...
