Re: Videotoolbox option not available

Of cause I compared the playing videos side by side. The stills are only a sample documentation to illustrate my impression of quality. I thought this might be helpful to other users. I know the frames are not perfectly the same, however in this scene 95% of the image does not move, just the butterf...

Re: Videotoolbox option not available

Hi again, thank you again for the answers. I was curious how the subjective quality of the renedring results is, so I compared the files of the software encoder (MacPro) and the "low efficiency hardware encoder" (MacBook Pro): https://imgur.com/NikQfyD To me it seems there's no difference, the file ...

Re: Videotoolbox option not available

Hi, I double checked: The job with the out file name ending with "constant quality" was _definility_ configured to VBR with Q=21. I re-opened the finished job from the queue und I can confirm this setting. However, I agree that the 2 logs of the MacPro jobs seem to be "flipped" regarding the encoder...

Re: Videotoolbox option not available

Also your "quality 21" encode is not, it's a 2500kbps target. Classic example of why logs are more useful than user claims. Well, as you can see in this screenshot the encoder setting is set to VBR with quality 21: https://i.imgur.com/ssStoGd.jpg https://imgur.com/ssStoGd Or is that setting just no...

Re: Videotoolbox option not available

Because there is no QuickSync on Xeon cpus, and I don't remember if there is a hardware encoder on the D500, but clearly it's not supported by Apple. With such Mac you will have much better quality and speed by using a software encoder like x264 and x265. Hello, I have an additional question: You s...

Re: Videotoolbox option not available

I fully understand.
If any further encoding questions rise I will of course post the log. In this case I saw in the log that there is no additional information about the system, other than I described manually.
Thank you you for the answers!

Re: Videotoolbox option not available

An Activity Log is required for support requests. Please read How-to get an activity log? for details on how and why this should be provided. Sorry, but as there's no "activity" problem I did not post an activity log. My question addresses the availabilty of a feature on certain system configuratio...
