Question / Help Quicksync video

I have been messing with all the different Encoder settings and find that Quicksync works the best in terms of performance and recording quality. That is all thrown down the drain once I actually render out the video with either Adobe Premiere or Sony Vegas or any other software I've tried through trial versions. I do not know what it is but when I actually playback the actual recorded file it looks good but occasionally if you skim through too fast it artifacts/glitches out a bit which is why I think the rendering is affected. Does anyone also render out (quicksync) video through Adobe and have no issues? If so please provide me with the settings that work for you.

P.S this also occurs with h.264 (render portion, not playback) and only doesn't happen with x264. I really want to figure this out because again Quicksync offers no performance impact whatsoever and good quality but once I render it out through a different program it goes to shit...

If the video plays as intended at normal speed, it's likely a playback issue. These problems should be non-existent on a site like YouTube.

Use Quicksync for recording within OBS. This way you have the full CPU available for the application/game you record. Use one of the predefined settings in the simple recording mode (high quality or better indistinguishable quality). But in postprocessing tools like Adobe Premiere, don't use a hardware encoder for rendering the final video. These tools use encoder settings that result in terrible quality in comparison to software encoders.

its known problem with QSV, since very long time. workaround is to record to FLV and then remux to MP4 in obs itself. you can find option to do it in FILE menu

I have an AMD RX 480 card so I am unsure whether Adobe is using it or not, I doubt it, also Sony Vegas doesn't seem to utilize it either because I see no difference when i use CPU Only or OpenCL if available. The settings I've found to work the best with quicksync was QCP at around 15-16 as it makes the bitrate higher than the 65000 cap you get with any other mode. What is recording in FLV a workaround for, does it make it so the codec isn't so complex for an editing program such as Adobe or is a playback workaround so i am able to watch it back without artifacts and such?

P.S appreciate the feedback also I think the artifacts may have to do with the player VLC however Quicksync video in general, takes alot of CPU% to watch for some reason, regardless there's still playback issues on that matter. Again not sure if just me...

Here are my last two log files incase anything is wrong.

Ignore the FPS 120 I was messing around :P
