I use Nikon SLRs among a suite of other video cameras for professional corporate videography. The latest full-frame Nikons have proven to be good solutions for a higher-end look. As with all SLRs, they are far from the convenience of a typical, all-in-one ENG type camera and as with all SLRs their video capture quality is lacking. My solution if the Nikon is ...

Since you're scaling 2x or more, your best bet is to upscale the DV again using Avisynth with the nnedi rpow2 filter, then scale, if necessary, to HDV. (With some tangible details, I can provide an example script.) Trying to sharpen the upscaled videos will produce worse results than the above method.

There are a few video quality metrics available for you to use, primarily SSIM and also PSNR. You can use ffmpeg to convert the video and then compare the output.

The camera is not the only issue here. If you have Nikon lenses you can get great footage with a D750. I am sending my Sony A7S back to BH because of horrible focus issues in low light. If a scene is not well lit there are issues no matter what camera is used. You need a good prime lens to shoot in low light, not high ISO.

If you are a fan of DSLRs, Canon cameras have modified firmwares where you can automatically restart the recording on a new file once you reached the limit. Check for ML ;) Obviously what you will do is concatenate the files in order to obtain a full lenght footage at the end. Consider that this is something that you could use to run up to 3-4 times the ...

Yes, it's powerful enough, even to edit features ... as long as: you use low-resolution proxies (copies) for long projects. you edit from an external drive with USB3 or better and not from your computer's HDD (avoid stuffing your HDD with large data files anyway).
