There is an option in VP16 to auto create video proxies if its UHD. That works and does create proxies - believe 1080p gets created. What I'd like to know - Are there any options to control the how the proxy file gets created? Like can I specify I want the proxies to be 720p videos at a certain bitrate instead of what VP wants to provide out-of-box? Would I have to resort to creating my own proxies outside of VP and doing some kind of directory or video swap to customize a proxy file. I'm working on an older computer so its understandable my preview of even the proxies is going to lag, but there are some encodings/file containers and bit rates that would work better as a proxy for me. Can custom proxy settings be done in VP through some config tweaking, and if not, can you point me to a good tutorial/write up on a way to swap in custom proxies so I can swap back to original on render?
