i need technical video help please


Recommended Posts

I would be grateful if any could suggest reading matter or website , that will explain about shooting in a given codec, why it has to be (,or does it?.) get converted to rec702 and do you convert if you want to output in 4k  and so on. I understand mostly what the various components are its their relationships to one another that is abit of grey area to me.

I hope this make sence to someone and I dont get my heat bitten off for posting this.

I don't have any personal experience in video, but this seems to be more than just an introduction into the matter. Hope this helps.  BTW, are you sure about the rec70??

No should have been 709 thanks for the help

    • Cropping is what I was thinking. Mainly for wildlife or sports. So it's really coming down to the a7iii, a7riii, or a7iv. All those have larger pixels than the Sony a6500 which as I understand, will provide better dynamic range and less noise. The Sony a7riv and a7rv both have smaller pixels than the a6500, although the sensor is backlit. Not sure what difference that makes over the a6500. Anyway, thanks for the input again!
    • On pixel level the a6500 will be pretty similar to the A7Riv, so you'll be disappointed by the ISO performance of the R-series cameras when pixel peeping. However, it has 2.5 times as many pixels so when printed/viewed at the same size, the noise in the picture from the R series camera is averaged over 2.5 times as many pixels, much reducing the 'perceived noise' on image level. This is the reason why all same generation fullframe cameras provide similar 'perceived noise' when viewing an image at a fixed size, whether the camera has 12, 33 or 62 MP: the pixels from the higher MP camera are noisier but the noise is averaged over a larger number of pixels in the eye (actually, brain) of the beholder. Only buy the higher MP camera if you actually need all those pixels (e.g. print larger, crop more).
    • Thanks, I appreciate the insight. I saw a video comparing the noise on a Sony a6500 and an a7iii. The a7iii was phenomenal. If the r series does as good in comparison to the a6500 then I may choose either the a7riii or just go with the a7iv.
