I am currently in the process of editing the footage I took during my last summer vacations. I usually keep all my dashcam footage so I can create a timelapse of scenic roads. My dashcam is a Garmin and it produces a .mp4 clip every minute. So for several hours drive, I end up with hundreds of files, making it a pain to edit directly. Thankfully Vegas Pro support nested timelines, which is not new, I was using it in VP 14.

I had already done most of my nested timelines and created the required proxies. It has been fairly smooth and very fast even for hours of footage. Yesterday, I realized I forgot to create a few for the last day of vacations. I did my usual workflow and to my surprise, the proxy creation was terribly SLOW, it took more than 15m for a single nested project.

Obviously something was wrong and I know I made changes to my PC. I knew I was able to get 1m per hour with build 334 so it was not this. I upgraded the Nvidia driver to the latest but proxy render barely uses the GPU so I kept searching. One thing that was different was a recent installation of my older version of Vegas, 13 and 14.

Sure enough I went ahead and uninstalled those. I deleted my proxy file and re-created it. Bam, 1m55s instead of 15m.

Looks like older version of Vegas is interfering with VP18. Am I dreaming that or someone else can confirm?
