What exactly does Maximum Render Quality do?

Its description in the documentation simply says that it sharpens the image if it's resized, and takes more processing power and memory to make the encode. But what does that function actually do? Does it simply use a bicubic resizer, with a bilinear/nearest neighbour used for default? I couldn't find any description of what's happening to my image on a technical level.

Here is some background information.

Maximum Render Quality CS5.5

My project is about 1hr 15 mins long, covering 8 sequences.
3 days ago, I encoded using the MPG2-DVD preset and burnt a trial disk with an Encore project.
After reviewing the disk, I made a few trivial changes to the PP project and encoded again.
Exactly the same encode settings except I checked Maximum Render Quality.
This time, it took FIVE TIMES longer to encode, and I cannot see any difference in disk quality.
What does checking Max Render Quality do?
Would you expect it to take 5x?
And would you expect a better quality disk?
Thanks

Jim,
Bill and I are testing this extensively for the new PPBM6 test and on our current time-line, which is an AVCHD 1080i-29.97 source with numerous effects, fast color corrector, brightnes & contrast, gamma correction, gaussian blur and 3-way color corrector and speed slowed down by 50%, for a total duration of 2;39;04 exporting to MPEG2-DVD with a preset of NTSC 23.976 Widescreen High Quality I have just tested again the export times and it gave me the following results:
System
Hardware MPE On,
MRQ Off
Hardware MPE On,
MRQ On
Software MPE,
MRQ On
i7-3930K,
GTX 680
24 s
24 s
436 s (94 without MRQ)
i7-2600K,
GTX 680
NA
33 s
870 s
i7-980X,
GTX 680
NA
30 s
556 s
Now this test is taxing on the GPU, because there is frame blending, scaling and blurring going on during export, but I can not see any difference with or without MRQ with hardware MPE turned on. I ran several runs and they are consistently between 23 and 24 seconds on this test. Several things of interest here, the advantage the 6-cores have over a 4-core when using software mode only, and the difference between MRQ settings in software mode MPE.
PS. You may be testing this with AME instead of Direct Export. AME is seriously handicapped in CS6 and that may be the cause of your strange results. How does it look with your same test when you use Direct Export, because exporting a 1 minute clip without effects taking 1 minute contrasts seriously with my export of 24 seconds for a clip 2.5 times longer and filled with effects. You know that both Bill and I have rather tuned systems and when our software MPE exports take this long (436 - 870 seconds) there is something going on here I would like to know more about.

Maximum Render Quality not installed

I am using Premiere Pro CS4 and did not see the Use Maximum Render Quality when exporting a video, my only choices are "Use Preview Files", "Include Source XMP MetaData", and "File Info".
I found one post that said it was in a update so I checked my verison and it said 4.0.0. I then checked for updated from the Help menu and ran that. version did not change and still no Max Render Quality so I found the download for PP CS4 4.2.1 and downloaded and unsipped it.
When I ran the EXE file it started but then stopped and said "Cannot Install click the Quite button". In the text of the window is said everything for 4.2.1 was installed except the language packs. Verson number is still 4.0.0.
What else can I try?
Thanks.

Thank you Ann
on the reinstall and updates, does the last update (4.2.1) for Premiere Pro CS4 have all the updated combined or do I need to run them one at a time?
also does the Encore update (4.0.1) run or included with the Premiere updates?
I will do this starting monday, i hope to have this 2,000 ft project done tonight so I can deliver it tomorrow but will keep my data and rerun it after the update if Max Render shows up
Thanks again

Turning on Render at Maximum Bit Depth and Maximum Render Quality crashes render every time

I've tried a few times to render an H264 version of my Red media project with Maximum Bit Depth and Maximum Render Quality. Premiere crashes every time. I have GPUs enabled. Are people using these settings with Red media and successfully rendering?

To answer your specific question did you see the tooltip?
I beleive it allows for 32-bit processing (16-bit if unchecked). Per the project settings help file at http://helpx.adobe.com/premiere-elements/using/project-settings-presets.html
Maximum Bit Depth
Allows Premiere Elements to use up to 32‑bit processing, even if the project uses a lower bit depth. Selecting this option increases precision but decreases performance.
The help file for export is somewhat less informative about what it actually does but does point out that it is the color bit depth - http://helpx.adobe.com/media-encoder/using/encode-export-video-audio.html
(Optional) Select Use Maximum Render Quality or Render At Maximum Bit Depth. Note: Rendering at a higher color bit depth requires more RAM and slows rendering substantially.
In practice the simplest suggestion is to export twice - once with / once without the setting and compare the time taken and perceived quality.
Cheers,
Neale

"Maximum Render Quality" Better to turn it OFF when using CUDA MPE?

http://crookedpathfilms.com/blog/201...port-settings/
"IMPORTANT NOTE ABOUT RENDERING TIME: Make sure you do not select “Use Maximum Render Quality” if you are utilizing the accelerated GPU graphics (Mercury Playback Engine). This will not improve your video and will only slow down the rendering speed by as much as 4 times!"
http://blogs.adobe.com/premiereprotr...e-pro-cs5.html
"For export, scaling with CUDA is always at maximum quality, regardless of quality settings. (This only applies to scaling done on the GPU.) Maximum Render Quality can still make a difference with CUDA-accelerated exports for any parts of the render that are processed on the CPU...
When rendering is done on the CPU with Maximum Render Quality enabled, processing is done in a linear color space (i.e., gamma = 1.0) at 32 bits per channel (bpc), which results in more realistic results, finer gradations in color, and better results for midtones. CUDA-accelerated processing is always performed in a 32-bpc linear color space. To have results match between CPU rendering and GPU rendering, enable Maximum Render Quality."
Here is what I got out of after reading those two sites:
I should turn it off for it's always ON (when CUDA MPE is used) regardless I check or uncheck it.Turning it ON only offloads the calculation to CPU (instead of GPU) hence slowing down the previewing and encoding performance.
So I guess I should have Maximum Render Quality setting turned OFF in both of squence settings and export settings.
However, David Knarr of Studio 1 Productions suggest otherwise:
http://www.studio1productions.com/Articles/PremiereCS5.htm
"When you startup Adobe Premiere CS5 and you don't have a certified video card (or one that is unlocked) the Mercury Playback Engine is in software rendering mode and by default the Maximum Render Quality mode (or MRQ) is to OFF.
(Maximum Render Quality mode will maximize the quality of motion in rendered clips and sequences. So when you select this option, the video will often render moving objects more sharply. Maximum Render Quality also maintains sharp detail when scaling from large formats to smaller formats, or from high-definition to standard-definition formats. For the highest quality exports you should always use the Maximum Render Quality mode.)
When you unlock Adobe Premiere CS5 so the Mercury Playback Engine can use almost any newer NVidia card (or if you are using a "certified" NVidia graphics card), the Mercury Playback Engine will be in the hardware rendering mode and the Maximum Render Quality mode will be turned ON.
Since the software mode is not set to maximum render quality, it can sometime render faster than the hardware render, but a a loss in qualitly. If you set the software to maximum render quality you will see that it is very, very slow compared to the hardware render.
Here is how to set the Maximum Render Quality.
1) Open up Premiere CS5
2) Click on Sequence at the top of the screen
3) Then select Sequence Settings
4) At the bottom of the window select Maximum Render Quality and click Okay
It is always best to be using the Maximum Render Quality mode,"
Now, I'm lost.

Okay, I am loosing it..... You are correct.
I am not sure what I was remembering, I could have sworn that when I loaded Premiere CS5 for the first time before I unlocked the video card, the Maximum Render Quality mode was NOT checked. Then when I unlocked the video card, the Maximum Render Quality mode was check to ON and I didn't set it to be On.
I just when back and uninstalled Premiere and re-installed it, to see what was going on and I was totally wrong.
Sorry for the mistake and I will be updating the article on my website in the next 15 min.
Also, I have written a small program to do the unlock automatically. The program is free and it works with the cards listed under the Automatic Mode.
If your video card isn't listen, just let me know what your card is and what you typed into the cuda cards file and I will add it to the program.

Maximum Bit Depth /Maximum Render Quality Questions

Maximum Bit Depth
If my project contains high-bit-depth assets generated by high-definition camcorders, I was told to select Maximum Bit Depth because Adobe Premiere Pro uses all the color information in these assets when processing effects or generating preview files. I'm capturing HDV using the Matrox RTX-2 Hardware in Matrox AVI format.
When I finally export my project using Adobe Media Encoder CS4, will selecting Maximum Bit Depth provide better color resolution once I post to Blu-ray format?
Maximum Render Quality
I was told that by using Maximum Render Quality, I maintain sharp detail when scaling from large formats to smaller formats, or from high-definition to standard-definition formats as well as maximizes the quality of motion in rendered clips and sequences. It also renders moving assets more sharply. It's my understanding that at maximum quality, rendering takes more time, and uses more RAM than at the default normal quality. I'm running Vista 64 Bit with 8 GIGs of RAM so I'm hoping to take advantage of this feature.
Will this also help to improve better resolution when I finally export my project using Adobe Media Encoder CS4 and post to Blu-ray format?
Does it look like I have the specs to handle Maximum Bit Depth and Maximum Render Quality when creating a new HDV project with the support of the Matrox RTX 2 Hardware capturing in Matrox AVI format? See Below Specs.

Just some details that i find useful on maximum render depth
You really need it even with 8bit source files, when using heavy grading/multiple curves/vignettes. If after grading you see banding, go to sequence > sequence settings from the top menu and check "maximum bit depth (ignore the performance popup), then check again your preview (it will change in a second) to see if banding is still present in 32bit mode. If no banding, you must check it when exporting, if banding is still there, change your grading, then uncheck it to continue with editing.
Unfortunately Maximum bit depth exporting is extremely time-consuming, but can really SAVE YOUR DAY when facing artifacts after heavy grading, by completely or almost completely eliminating banding and other unwanted color distortions.
Use it only for either small previews or the really final output.
Best Regards.

Maximum Render Quality no longer shown.......

I'm using CS4.
I have had great success with Steve Bellune's suggested settings for exporting media and encoding HDV 1080 60i projects for DVD burning.
Now, all of a sudden, for some crazy reason all I have on the small drop down menue are the following choices:
    Use Preview files
    Include Source XMP Metadata
    File Info.....
There is NO Maximum Render Quality choice like I have had in the past.
Might be my imagination, but I seem to see many, many more Jaggies on the DVDs.....
As far as I know, nothing else has changed.

What exactly does a new poster have to do to get permission to post images?

Recently there was a forum update that disabled new posters to add images
(AND links?) Supposedly this was to reduce spam. So far so good.
Not surprisingly, immediately after the update we have numerous posts in the Forums Issues forum complaining about this feature and no doubt plenty of users just submitting to this policy in silence.
This whole feature is a SEVERE (that's right. bold AND in caps) hindrance. I don't have the stats, but I'm sure a considerable percentage of
(non spam) original posts are from new users with no previous forum activity. Pictures are especially important in the Chart Control forum as visualization is what charting is all about.
(This is the forum I frequent. So yes, I'm biased.)
Ofcourse, I'm sure the forum developers have weighed the pros and cons and studied the stats and then decided what to do after serious consideration...
The question is: What exactly does a new poster have to do to get permission to post images? Wait for how long? Reply to a confirmation email? "Participate" more?
(Say it ain't so.) How much more?
If there really is a workaround by adding an image tag with the edit html button, I don't want to hear it. It's as silly a way to add images as in the before times, the long long ago.
(Also, if this is possible, this whole restriction feature is actually worse than useless. Spammers will exploit this sooner than later. (A very good point made by our dear friend Quincy in a post that has since been deleted it
seems.))

I believe answering that question defeats the purpose of having the "feature".
I suspected as much.
I was hoping to add some explanation to the chart forum FAQ, I guess "Body text cannot contain images or links until we are able to verify your account."
(if this really is the only message new posters get) will have to do.
I still feel this is more of a hindrance to the quality of the forums than not. As confirmed it seems by Naomi, spammers already have a workaround.
Sipla, it sounds like we should add this FAQ to this article:
http://social.technet.microsoft.com/wiki/contents/articles/7359.forums-help-faq-en-us.aspx
What do you suggest?
What does the message say to the user who cannot post links and images yet? We should map to that language.
Thanks!
Ed Price (a.k.a User Ed), SQL Server Customer Program Manager (Blog,
Twitter,
Wiki)
It says "Body text cannot contain images or links until we are able to verify your account."
If this means you will get a verify email, then you should get a verify email. The message infers that either action will be taken by the forum mods that will be apparent to the user or that the user needs to take some sort of action.
If this is not the case, the wording needs to be changed; it should not mislead you. This is an incredibly vague status message.
I do not have any record of a verify email in my inbox history. All I have is an email this morning from MSDN Site Support (I also posted a request yesterday in MSDN Site Feedback) asking me which account I needed verified. I only have one account.
Almost immediately after I replied, I was able to post links and photos. Honestly I do not know which came first though, the "verification" or my reply to the email or someone noticing the thread about compaining about it a month after signing up.

YouTube Video: Do you recommend use maximum render quality?

YouTube Video: Do you recommend use maximum render quality?
Is it worth the wait?
Do you use it for YouTube videos?
How much longer does it take to render / export?
Twice as long or ?
Just looking for a general comparison in time based on with and without.
I know it depends on variables.
I'm already in the process at 21%. (15 mins.)
Just curious for the future.
Thanks.

Hi,
You can use the "Maximum Render Quality" whenever you are scaling down the resolution from larger frame size to smaller frame size while exporting.
It requires more RAM during export & should be used whenever maximum quality output is required. However the export process may be slower than the normal export.
Thanks.

Maximum bit depth-maximum render quality when dynamic linking

Hi
A bit confused by the use of Maximum bit depth and Maximum render quality as used both in Sequence Settings and also as options when rendering in AME.
1 Do you need to explicitly enable these switches in the sequence for best quality or, do you simply need to switch them on in AME when you render in Media Encoder?
2 When dynamic linking to After Effects, when should you use an 8 bit vs 16 or 32 bit working space, and, how does this bit depth interact with the maximum bit depth, maximum render quality in PPro?

Hi jbach2,
I understand your confusion. I'm like that most of the time I'm working. *chuckle* The two settings you mentioned are two completely different parameters affecting (or is it effecting) your video. You do not need to enable them within the sequence itself unless you want to preview video on you program monitor at the highest quality. I personally don't recommend it, as it's a tremendous resource hog, (the program even warns you when you try to click them) and unessecary for improving final output. Again, do not enable these options in your sequence settings if you are only wanting a high quality export. Doing so will greatly reduce your editing performance unless you have a high-end system. ...and even then I don't think its worth it unless you're editing on a huge screen with a Director who wants to see everything at a maximum quality during the edit process.
Keeping it simple...
Resizing your final output video? Use Maximum bit depth.
Starting or working with high bitdepth sources? Use Max Bit Depth.
When/where do I enable these? In the AME only. ^_^
Why?:
Enabling the Max bit and Max render only needs to be done when you are exporting. They both serve different functions.
Max Render aids in the scaling/conversion process only. My understanding is that you never need to enable the Max Render Quality (MRQ) unless you are exporting in a format/pixel ratio different from your original video. For example, when rendering a 1080p timeline out to a 480p file format, you'll want to use MRQ to ensure the best scaling with the least amount of artifacts and aliasing. If you're exporting at the same size you're working with, DON'T enable MRQ. It will just cost you time and CPU. Its only function is to do a high quality resizing of your work.
Maximum bit depth increases the color depth that your video is working with and rendering to. If you're working with video that has low color depth, then I don't believe it will matter. However, if you're working with 32 bit color on your timeline in PPro and/or After Effects, using lots of graphics, high contrast values, or color gradients, you may want to enable this option. It ultimately depends on the color depth of your source material.
The same applies to After Effects.
Create something in AE like a nice color gradient. Now switch the same project between 8,16,32 bit depth, and you will see a noticable difference in how the bit depth effects your colors and the smoothness of the gradient.
Bit depth effects how different plugins/effects change your overall image. Higher depth means more colors to work with (and incidentally, more cpu you need)
Just remember that "DEPTH" determines how many colors you can "fill your bucket with" and "QUALITY" is just that, the quality of your "resize".
http://blogs.adobe.com/VideoRoad/2010/06/understanding_color_processing.html
Check out this adobe blog for more info on color depth ^_^ Hope that helps!
----a lil excerpt from the blog i linked to above---
Now, 8-bit, 10-bit, and 12-bit color are the industry standards for recording color in a device. The vast majority of cameras use 8-bits for color. If your camera doesn’t mention the color bit depth, it’s using 8-bits per channel. Higher-end cameras use 10-bit, and they make a big deal about using “10-bit precision” in their literature. Only a select few cameras use 12-bits, like the digital cinema camera, the RED ONE.
Software like After Effects and Premiere Pro processes color images using color precision of 8-bits, 16-bits, and a special color bit depth called 32-bit floating point. You’ve probably seen these color modes in After Effects, and you’ve seen the new “32″ icons on some of the effects in Premiere Pro CS5.

Maximum Render Quality

Is it true that the only time to use Maximum Render Quality on exporting is if you are scaling footage? If the size of your footage does not change on export there is really no reason to use this option. Is this correct?

Thanks Jeff,
Is MRQ only for deinterlacing or does it actually help with scaling also?

Export with Maximum Render quality

I'm about to output in 4K a final master project file for a short film that was primarily shot in 4K, but also has some clips in 1920 by 1080 and even 1280 by 720.
I'm not concerned with how long the export takes. Is there any downside (or benefit) to activating "maximum render quality"? What about "render at maximum depth"? 24 bit or 48 bit?
I would think for a master file, you'd max out all of this, no?
Thank you for any and all input. I will use the master file to generate Vimeo, Apple TV, etc. dubs.

Use Maximum Render Quality: Mostly affects upscaling of content. If you're not upscailing, you won't notice much of a difference. Looks like you might be upscaling content to 4k, so I'd say yes to turning this on.
Render at Maximum Depth: What is the bit-depth of your source content? Do you have any content in your sequence that would benefit from the higher bit-depth?
If you really don't care how long it takes to export, you might as well turn these on. The drawback is the longer encode time.

Dumb Question - what exactly does "Static" mean

What exactly does static variables and methods? What are they for?
I know "final" means once you set it that's it..but what does static mean?

HT4859 when you go to do this it say that your iPod or whichever device will no longer be backed up to the computer it is currently backed up to, what exactly does that mean? Will i not be able to sync my iPod from that computer?

when you go to do this it say that your iPod or whichever device will no longer be backed up to the computer it is currently backed up to, what exactly does that mean? Will i not be able to sync my iPod from that computer? Please help me and answer either or both question detailed thanks

Normally when you sync your device it is automatically backed up to your computer as the first step in the sync process. When you choose to start backing up your device to iCloud, iTunes stops automatically backing it up on your computer when you sync. That's what the message is telling your; that you are now backing up to iCloud and not to your computer each time you sync. You can still manually back up to your computer any time you want by going to the Summary tab and clicking on Back Up Now under Manually Back Up and Restore.
You can still sync your device as you did before, it just will no longer back up automatically when you do.

What exactly does the AppleCare cover for MacBook Pro with Retina Display?

I purchased the extended protection plan for my MacBook Pro with Retina Display 15" and my question is what exactly does it cover in what kind of situations (i.e. viruses, damaged ports, damaged charger, etc.)? I want to be able to take full advantage of the protection plan since it was a pretty big whole in my wallet.

AppleCare covers all the problems you have with your MacBook Pro with Retina display and the peripherals which came with it (your charger) if you have a hardware problem that you didn't cause. For example, after 2 or 3 years and 1000 charges, OS X says that your battery has to be replaced: in this case, you have to pay for the battery, because batteries have got a lifetime, and Unibody Macs batteries have got an average lifetime of about 1000 charges.
However, if the RAM gets damaged and you haven't done anything to cause it, you will get your computer repaired or replaced for free. AppleCare in a MacBook Pro with Retina display is very important, because near all the parts are soldered into the logic board and repairs are expensive
