just in case anyone is still following my quest;jimmy - the split button in that context simply takes any scene on your timeline and cuts it in two so you can move parts of it around, like if you have one 60 second scene and split it in half you'll have two 30 second scenes. there is no in/output point setting involved when doing a split.
OK, so I pretty much established that VideoPad is not working the way I want, so I wasted a day downloading installing and uninstalling half a dozen other popular free/cheap editors until i found;AVS Video Editor 6.3
this program does what i want, with many convenience features. you drop your imported video file into a timeline, then right click on and it select "Multi-Trim" which opens up another window you can even move to a different screen if you have more than one. in this Multi Trim window you can designate multiple sets of Mark-In Mark-Out points as many times as you like. there is even a zoom button to see the current play duration line in higher resolution making it easy to mark scenes only a few seconds long or between each other. once you are done marking the entire video file, you hit an Add button once and the program moves all the scenes you marked into the timeline of the main window. there you can rearrange them, add transitions, titles, whatever you like.
two major PRO's i found with AVS is it allows you to import a wider variety of screen sizing and video file formats such as RM's and MP's but has a low tolerance for any sort of file corruption, so you may still need a separate video repair or conversion tool. thankfully AVS does use multiple CPU cores at 64bit while producing your final product file to disk
, so the performance difference between AVS and VideoPad was minutes instead of hours. the only CON i found thus far after some casual use is the final product files don't show accurate scene splicing. I often found my edits were many extra frames different from what I had Marked on the Multi-Trim screen. I can forgive this because I'm using it casually, but people looking for better finished product may have to look elsewhere. if you download AVS you get a full version that puts a watermark on your finished videos until you pay to activate it. but if you google around there are plenty of activator cracks that seem to work fine
