So I (like everyone else) am trying to make the best quality movies possible, most like their original imported footage. But im still getting some artefacts in the produced video (particularly in very dark corners).

Im using a GoPro 4 silver filmed at 1080p 60fps.

I set my timeline FPS to 60 FPS and produce the movie to as close to the original format as possible.

I produce a custom template that is MP4 1080p 60fps, with the same bitrate as the total bitrate shown in the original footage (think its about 30146kb). I leave ticked the box for fast video rendering technology on the hardware video encoder selection (this was default) Now, I'm now saying it's not good, it really is great (before youtube gets its hands on it) but I just think it could be slightly better, is there anyway to make it completely artefact free?

If you do not use Fast Video Rendering Technology (Hardware Acceleration), you will likely eliminate any artifacts in the video.

CPU rendering is nearly always clean.

SVRT is also usually clean.

Thank you Carl. Sound advice. I did wonder if "fast" was not best for quality. (usually isnt).

Any way of getting youtube to not ruin the lovely end result?

here is the video by the way. Very pleased with it, fairly simple. Best to view it 1080p60fps

next one will be even better without FVRT

Well, we have a problem, I get this error when I try and produce it without fast ticked? (Also wont let me select SVRT)

I've made sure everything listed there is updated? still no good?

Put up a larger image. the one you have posted is too small to read.

If you disable any Hardware acceleration in Produce, your quality of the output video goes up, as in the best your can do.

Just click the image to view it bigger Carl. It says,

"production unsucessfull, please ensure your graphics card driver is up-to-date. And update to the latest version of Windows Media Player or QuickTime Software. You can also output the producion in a different video format.

I have checked and everything is upto date.

Did you try a different profile? MP4 or WMV, or H.264 AVC.

I haven't (seems silly) but for two reasons. I always produce in MP4. 1: I was under the impression you should always keep the production in the same format as the original files (which is MP4)

and 2: I was under the impression than MP4 was the "best" format (most detail, least artefacts).

So I was thinking that MP4 produced with "fast" would still be better than another format maybe produced without fast.

What are your thoughts? Thanks.

Again, just looking for the best possible setting for the best possible results.
The original footage is nearly always this (Total bitrate changes slighty from video to video)

You can use your favorite MP4 profile, but try producing without any "Fast technology". CPU rendering is always the best, it may take longer than with "Fast", but you will get a much cleaner video, no artifacts.

Hardware (Fast) rendering is a function of your video card and software. Changing the version of video card software may make more artifacts or less.
Which is why if you do not use the video card and software, you stop one source of artifacts.

Bitrate is variable, most cameras use variable bitrate. The advantage is in some scenes there is less changes from frame to frame so the bit rate does not need to be so high.

Thats my problem though. I get that error message (picture I posted) when I try and produce it without fast. It will only let me produce it fast. That's the problem.

Then you have something wrong with your PowerDirector installation.
What version of Powerdirector do you have? Click on the word POWERDIRECTOR on the upper right.

I suggest that you un-install, Reboot, then re-install.

Those Codecs for all of the native video Profiles in Powerdirector are built into the program. If you cannot render using only the CPU, you are missing parts of Powerdirector.
