I'm scrubbing videos but am a novice with output. I m creating and tagging subclips (wish subclips were searchable...!) and want to export the subclips in as much as original quality as I can.
What is an export option that allows me to keep the file exactly the same without recoding?
Depending on the input format you may be able to rewrap to MOV or MXF which would be completely lossless (it just copies the audio/video streams to a new container). Note that this may not work/fail for some formats, so it's best to try it out.
If you need to re-encode it depends on various factors. If you're trying to save disk space and encoding speed is not a concern HEVC may be a good choice (lossy, but you can set it so that it's barely/not noticeable); if disk space is less a concern and you want to prepare your footage for editing ProRes is a good option.
