Does Bitrate affect resolution?

Will a smaller bitrate vs larger one affect resolution?

No Fran but resolution will affect time
when buffing, copying, transferring at
any given bitrate.

So, I'll jump in on this, is bitrate more a concern with photos or video?

We really need a context for this question, because the term could apply to data transfers of any sort. Normally, the term is used to refer to the speed at which video data is sent. We also use the term to annotate the quality of video (a higher bitrate carries more data than a lower bitrate, making the video quality higher).

I've never heard the term used for photographic images. However, bitdepth is used to describe the quality of the RGB components in a pixel. And no, bitdepth doesn't affect resolution. Resolution is about how many; bitdepth is about the quality of each.

So, we really need a better question. At the very least, a context.

"Will a smaller bitrate vs larger one affect resolution? "...No, but like stated, the question is a tad murky.
Why so serious?

is it video or still related?

Your resolution is determined by the amount of pixels plus the resolving capability of the lens. Say if you put a pinhole lens in front of a 24mpx sensor you will end up with the same 24 million pixels worth of information but the detail there will not be as much as if you used some decent macro lens.

The bit depth determines how many bits are used to describe the luminance of each particular pixel. With 8-bit there are 256 levels and with 16-bits there are 65536. The more bits used, the larger the size -- e.g. (assuming no compression) the 24 mpx image in 8 bit will be half the size of the same resolution but in 16 bit.

The deeper the bit depth, the smoother the gradients and transitions between the luminance levels of pixels, thus, less risks of posterisation in post. It is probably worth mentioning that in Photoshop, the 16-bit mode is in reality 15-bit, so the amount of levels is halved, Still enough.

She asked about bitrate, not bit depth. That's why we're asking for clarity on the question.

How to come up with a clear, precise question
when the subject is yet freakin' fuzzy?

In the digital world, photos or videos are boiling down to only
one thing: data, and data transfer is expressed as bitrate.
