wetrock 0 #1 October 8, 2014 I was in a different forum i read a post about Vegas playing choppy GoPro video and one user came up with a solution that worked for me. try at your own risk. here is a link to the thread. http://www.sonycreativesoftware.com/forums/ShowMessage.asp?MessageID=878671&Replies=56 this is the post that ex-planes what to do. QuoteOld smoke I had a bit of time today to look into what is going on. Some users noted that these 1080-60p GoPro files play well in VP11. I got both VP11 32&64bit versions, reinstalled it on my Win7x64 machine and yes, the file plaid well; 59.94fps at Best/Full. I then used a program to monitor the API interface and dll that is called upon when playing the file back. The dll in question is "mc_dec_avc.dll" at this location "C:\Program Files\Sony\Vegas Pro 12.0\FileIO Plug-Ins\compoundplug" I then copied the file from VP11 64bit over to VP12 and voila it plays at 59.94fps Best/Full! if you don't have VP11 64bit here is a link to the dll https://dl.dropboxusercontent.com/u/39278380/mc_dec_avc.dll Do not delete or overwrite the original VP12 dll but rather rename it; just in case. I haven't done any further studies but I did render it out and that worked well too. I hope that helps. Quote Share this post Link to post Share on other sites
