有人说这没关系，有人说这可以缩短出口时间，谁是对的？我们认为我们应该对FCPX进行测试，以查明预渲染时间表是否可以缩短导出时间。我们得到了一些有趣的结果！

  2. I have a problem when I tried to export the video, the load stays on 19% per hours and days I can't export the video. helpme please 🙁 I was trying everything

  4. Can someone please answer? I have top of the line MacBook Pro 16” everything speced up to the max. But this is what I do on FCPX:

    1. I edit videos typically they are 1080p but I specify the project to be 4K. Length is 40 minutes usually
    2. I add a logo overlay throughout the whole video
    3. I change saturation throughout the whole video
    4. I have some animation and video introductions but nothing fancy

    Here is my issue: The render takes 1 hour and the export takes 1 to 1:30 hours. Is that reasonable? What am I doing wrong?

    Oh my project is defined as ProRes 4444 HQ as well. Also I export on better quality 4K. Appreciate your answers

  6. Why are you cutting it up like that and rendering? Why don't you render the whole thing? of course it will take a minute or so. Render the whole damn thing and see how long it really takes.

  7. What about when sending to Compressor? Does rendering effect export time when sending to Compressor? Answering my own questions (I just watched a video of Steve Martin from Ripple Training): FCP uses the render files when exporting. When you send it to Compressor, FCP has to regenerate all the rendered files because Compressor isn't able to recognize/use those previously rendered files. This is because the share technology in Final Cut is much more advanced than the share technology in Compressor. So sending to Compressor will ALWAYS BE SLOWER because of the need to re-render the data.

  9. Great video, thanks for making it. I do feel like there's a hole in it though. The rendering of the timeline takes time. What I think some people mean when they say it makes no difference is that if you get to the end of a project and then let it render before exporting, it won't be any quicker than just going straight to the export. The reason you found the rendered timeline faster than the un-rendered one even for H264 is that the computational work was all done in the creation of the ProRes render, so it was just a straight transcode rather than a full render. I turn BG rendering off because I use adjustment layers for my grading, so any change I make, or retiming I do, anything, means the whole timeline has to be re-rendered anyway, so background renders are constantly being thrown out. I hope that made sense! If you have a better suggestion than adjustment layers for consistent editable grading I'm all ears. I'm about to give Color Grading Central's Cinema Grade a go as it can group shots itself. Thanks again for the video!

  10. This means that Final Cut X exports media from the ProRes assigned on timeline settings and not from original media?? ex: I got a prores 422 timeline and I want a master file on prores 4444 is this 4444 done from a 422 prores ??? Davinci has options to use optimized media, render cached images and for raw media as force debayer to highest quality, that we don't have on final cut… So the question is ; Does Final Cut X exports are from original media or from timeline codec? Imagine a Red raw file it will be exported from prores?Thanks in advance

  18. How was this even in question. It always has to render before it saves the export. So all you have done is use background render to remove that from the time equation. That seems blatantly obvious. BTW: For a video about editing, this video could have been edited down to 5 minutes max.

  19. That's understandable that exporting a rendered file will be much faster, since if you export it without rendering it adds both the render time then the export time, without keeping the rendered files in the project; which saves space; but takes more time to export.
    But what i always wonder about is if it renders then exports the sum of those two vs exporting without rendering .. which one would be faster ?
    Like for ex. sometimes u get a video where u apply a color grade at the end, or maybe add an adjustment layer with black bars, so is it better to wait for the video to render first on the timeline then do an export, or just export right away and it will take the same time ?

  24. Thanks for that!
    I think another intersecting comparison would be to also check out an unrendered timeline, start the stopwatch when we start rendering it and then export it, so we have 2 separate steps. That's for those who don't like background rendering turned on, but are then wondering if it's worthwhile to render before they export or not. I think that those who say it doesn't matter are talking about this scenario where they also need to consider the time it takes to render the whole timeline while doing nothing and just waiting for it to complete.

  26. Thank you for taking the time to put this out. Just upgraded to an iMacPro in the exact config as yours. Really impressed with the increase in render speed. Keep up the great work on your plugins- they ROCK!

  27. You are almost complety wrong. You don't count the time which takes when you need to render the project, we don't have rendering background on because of the lack performance (only when you leave the machine it is on)
