Carlo 4561 Posted September 2, 2021 Posted September 2, 2021 Hi, It looks like these have different video codecs. When playing back is one a direct play and the other a transcode?
rbjtech 5284 Posted September 2, 2021 Posted September 2, 2021 (edited) The framerates are also very different. The 1440p is 29.97fps (constant), the 1080p is 60fps (variable). So I would think the variable frame rate has something to do with the issue .. ? Edited September 2, 2021 by rbjtech 1
Eddie 12 Posted September 2, 2021 Author Posted September 2, 2021 @cayars Thank you for the reply I'll experiment and see what it does when I play it when I get a chance @rbjtech I didn't even notice 1080p at 60fps I'm going to experiment dropping it to 30 and seeing what happens

Eddie 12 Posted September 2, 2021 Author Posted September 2, 2021 I found the option of automatic 30 and 60 I'll pick 30 and see what happens thank you for the response 1
