If I want to view my video on 4K 55" TV what would be the recommended settings for rendering in Delivery tab? I tried the Vimeo 2160 but the result was not good at all. Lots of pixelation in the sky, not enough detail etc etc...I created my own for 4K output with bit rate limit of 55 Mb/s and that produced much better final video. But there are setting there which I have no idea what they mean and how they affect the final video quality. Any advice on this would be appreciated

Try this, adjusting Frame Rate and Keyframes accordingly.

Thank you. Is this screen shot from the Free or Studio version? I am on Free version at the moment (waiting for the USB dongle to arrive) and do not seem to have those options available.

Studio.

You may have to wait on this one...

Do not use h.264/265 compression in Resolve if you want best export results. If you must have a h.264/5 deliverable, export an intermediate codec and compress to h.264/5 in something like Handbrake of Shutter Encoder.

That would get it done in the meantime, but I do find the built-in encoders quite good at what they do, and deliver such to clients regularly.

I only go third-party encoder when I need to control file size.

So, there are lot more limitations in Free version than I would have thought...Can I expect the rendering process to be also faster in Studio? I have NVidia 2080ti in my PC and at the moment it is barely used (2%) during rendering (CPU 100%) and rendering takes about 3x longer than the video lenght. In PremierePro CC it took about half of the real time and GPU utilization was up to 90% and CPU about 10-20%.

The end result doesn't have anything to do with free version limitations, though you should pick up speed with the Studio version. h.264/5 are consumer formats, and don't enjoy in Resolve the same level of support they would have in more consumer-oriented editors. At least for now.

Only you can decide what's good enough, but I wouldn't deliver to h.264/5 in Resolve, for anything consequential. The encoders mentioned above can do better and with smaller file sizes.

I've been delivering (from a Mac) some stuff in H.264 and H.265 for Youtube and it seems reasonable in comparison to another person who uses Premiere Pro (on an older PC I think). Though maybe Premiere doesn't set the bar very high.

Going forward, I'm going to just do H.265 and not H.264, since I can cut the file size in half with the same quality and a slightly faster render time. This is on top of already using a lower max bitrate than the Premiere person, too. I'll have to compare to Handbrake. (Does Handbrake use FFMPEG under the hood, and what do you think about FFMPEG?) I'm using those codecs because that's what they've always used for uploads to Youtube, and I'm trying to push file size because I have a pitifully slow upload speed from Verizon and I can't even pay more to get faster.

In my humble opinion the workflow of Resolve-to-ProRes-to-Handbrake-to-h.264 delivers visually much better end result than Resolve-to-h.264, at least for my untrained eye. This is valid for Resolve 16 on Mac - I'm yet to test v17 on M1.

Cool, I'll remember this and try to do a comparison. Anything to make a smaller, yet better file is a big win. (Curse you Verizon with only 5mpbs uploads!)

(On a sidetone: the Premiere person had HUGE discrepancies in render times with H.265 taking2x or 3x longer than H.264 out of Premiere. My assumption is that they have an older computer which has some H.264 acceleration but not H.265. For me -- newish Mac -- the H.265 is actually slightly faster.)

Macs love ProRes, so I'll try the two-step through Handbrake. (And FFMPEG if I'm not confusing things here. In fact, with Resolve 17 I should be able to fire off a script after the ProRes render and could use that to push the ProRes through Handbrake to generate H.265.
