interesting video Dave, thanks for posting it.
Some good tips in there about workflow, but i am not as good as you for getting my spoken bits right which means more editing for me
I probably need to be better disciplined, stop and really think about what i want to say before each clip. I also say a lot of 'so' and 'erm' when filming which i also try and edit out, but does take time.
I'd 2nd all your comments about recording audio, setting your colour balance, framing right when your shooting rather than doing it in editing.
I do some post video & audio processing though, not much just some little global tweaks, video gets slightly more contrast and audio gets a fast limiter in case i knocked a screwdriver against a metal part and created a horrible peaky clack so all the audio should be no more than -6db. I also have some specific tight notch filters as well to kill some annoying hums from my PC which is right next to where i film.
Your setup is nearly identical to mine though, same core PC and software, though my tests consistently show better performance with GPU rendering, i know this is a thorny subject for you but i probably know why it didn't work for you when you tried it... if you ever want to know
I tried the smart re-sampling on and off, the only time it does benefit is when there is a change in frame rate from source to final render. I notice you record in 50 and render at 30 so disabling for you is the best option. My source and render are the same at 50fps so there is no benefit in disabling it unless i use time-shift and speed up a clip. Oh if you want a quick tip, you can multi select all your clips by selecting the first and end clip on the timeline with the shift key down, you can then disable the re-sample with one click for the whole project. What smart re-sampling does it if the output has more frames than the source it will take two frames and create a blended one to insert. Same goes for frame rate reduction, if it has to drop frames it will drop one frame and blend the adjacent frames together. I don't like what it does either and i do disable it when i speed up video because i dont like what the output looks like.
I don't keep my source footage though, takes up too much space and i probably generate more of it given i am less disciplined when shooting video. I do keep my 'master' final render and the upload file. The master is 1080P 50fps 25mbit video using the Sony AVC codec & 256kbit AAC audio, from that i make a second version using handbrake but drop the frame rate to 25fps and set the quality to usually 23 for the final upload.
The codecs in Movie Studio are utter pants for speed, if only it could match handbrake for settings, speed and quality of the output. Hopefully now magix have bought the line they will make some improvements because it's the biggest disappointment in the app. Setting the rendering threads number to the same as your physical cores helped me a little with rendering time BTW. So if you have 4 core with hyper-threading, set it to 4 not 8.
