I know these two ways and it would be hard to do without them After exiting the project, I almost always delete the entire folder with temporary files. Especially before exporting, because when exporting a movie with old temporary files, I have a guarantee that most of the video effects will not be saved properly. (So I don't understand why the program doesn't clean this folder on its own or at least update the video effects files.)
Without dividing it into segments, it would not be possible to do much either, but - and that's the problem - I used to be able to calmly edit an eight-minute-long segment, and since December the program was incredibly lagging already at four minutes. I don't understand what has changed. The program does not like any specific codecs, bitrates?
But the Proxy idea... That doesn't answer my question, but it would actually be a smart way to make the program easier. Funny I didn't think about it myself :D
It is like that for me. After its first installation, most of the multimedia files looked like MTV in the example: https://ibb.co/VV6H4dY (after reinstalling the codecs everything is again assigned to WMP, but extensions unknown to K-Lite remained). Not to mention a series of unnecessary options added to the context menu (Add to VideoPad Project, Stabilize Video, and for photos - Convert image file and Create slideshow) and setting his own star icon. When I tried to fix some problems with the program installation - I had to tidy up everything from beginning.
But well - it may be a little different for me. I use Windows XP, so maybe some old stuff works with him that you've stopped testing a long time ago. Maybe better you know about it, because VideoPad is one of the really few video editors that not only starts up but also works very nicely with such old computers.
