Slow Video Rendering w/ iMac i7

My new iMac w/ i7 processor is rendering video slower than old iMac w/ Dual-Core.
Any ideas? (FCE 4, rendering to external USB drive or internal HD)

What material are you working with? What is your source video, your sequence settings, etc. Are you running any other apps? How full is your system HD?
How do you know it's slower? What is the evidence? (real questions, not being funny)
Also, you shouldn't be using a USB drive with Final Cut; that could be part of the problem.

Z820 slow video rendering

Hi,
I work in a video production studio that is primarily Mac-oriented. We have two z820 workstations we want to incorporate into our workflows, and have upgraded them with 32gb RAM, Zturbo SSDs and Nvidia Quadro 5000 GPUs. We are hoping to get these stations to render as quickly or more quickly than the standard 2014 iMacs we have in the studio, but so far the machines are rendering a 4.5 minute 5K video sequence in about 12 minutes, as opposed to the Mac's 3 minutes.
I was wondering if anyone on this forum had famliarity with video editing (we use Adobe Premiere Pro) and GPU maximization. We're trying to get the z820s to at least match their Mac counterparts.
Currently the windows machines beat the Macs in transcoding and ingesting footage, going about 5x faster while transcoding Quicktime or R3D files into 1920 x 1080 HD quicktime, so I'm pretty sure they have the processing power to get the renders we want, i'm just not sure what video card/computer settings I might need to mess with to get there.
Any and all help is much appreciated!
Thanks,
Zach

Hi,
I have had some more time to think about your rendering issue. Please post your hardware configuration and Product Number.
How large are the data objects?
Think of your rendering process like a single transaction much like when you do an online query to a server. If just one of your transactions are slow then you may have a data object problem. Just for now temporarily assume that the hardware platform is stable but you can test that assumption by running some diagnostics if you so desire.
If all of the transactions are slow then think of the time line for the transaction. Typically the time line looking at the transaction linearly, is made up of three major queuing components: CPU, memory and I/O. You can start the Windows resource monitor before doing the rendering process and then look at the recorded results to determine where the bottlenecks reside. Are all of the expected number of processors and threads running at 100%? Is the memory utilization at maximum for the 32 GB? Are you seeking a lot of hard faults? Look at the disk queue length and I/O activity. What do you see? Historically with transactions, I/O is the biggest bottleneck.
What are your biggest performance bottlenecks with your rendering process? Once you give me some more information then I can make some more suggestions. The above graphics that I had referenced may not solve your issue.

Slow video rendering etc. in FCP/Premiere/etc. Radeon problem with Mountain Lion?

My mid 2010 Mac Pro was working fine until I installed Mountain Lion. My colleague has the exact same setup as I do, but has SnowLeopard and no issues. Mountain Lion may or may not be the problem.
Now, all video takes a really long time to render or encode or export, especially .mov. Testing on FCP, Premiere, Compressor, and Media Encoder, Quicktime 7, results in really long times for anything involving video processing.
All other video works fine; playback capture, etc. Just processing of video takes a really long time.
I thought it might be an issue with the video card?

Take a look at this article, originally written for MacBook owners. There are some things in 10.7 and 10.8 that do not seem to upgrade happily -- they leave some tasks eating up CPU cycles when they should not be.

New 2012 iMac slower SD renders from AE than a 2007 MacPro?

Hi there -
I just purchased a new iMac for our small production house. 99% of the time, we are loving the machine: the performance, the stability, the speed, are all significant improvements over our 5 year-old Mac Pros. We have run numerous tests comparing the performance of our new iMac to our old MacPros and on average, the new iMac is performing 2-4 times faster than our Mac Pros. However, we've run into one specific issue where our iMac performs worse than our older MacPros, and unfortunately, this one issue is a major part of our everyday work flow and currently prevents us from converting all of our old Mac Pros to new iMacs. I'll try to be as brief yet detailed as possible so you have all the specs.
Our problem is when we render out standard definition Quicktime Animation MOV's out of Adobe After Effects CS5.5, our new iMac performs 30-100% slower than our 5-year old Mac Pros.
Here are the machines we're comparing:
Mac Pro (OS X 10.6.8)
2 x 3 GHz Dual Core Intel Xeon, 10 GB RAM,
NVIDIA GeForce 7300 GT 256 MB VRAM
vs.
2012 27" iMac (OS X 10.8.2)
3.4GHz Quad-core Intel Core i7, 32 GB RAM
NVIDIA GeForce GTX 680MX 2GB, 3 TB Fusion Drive with (128 GB SSD)
Both machines are running Adobe After Effects CS5.5 and are using the exact same projects and assets. Source files were stored on the desktop for each test, and outputs were sent to the desktop. We have also manipulated Multi-Core Processing settings and RAM-Allocation settings and while we saw slight differences in render times on the iMac, it was never close to competing with the MacPro.
Here are some of the other test results we get that meet our expectations:
                  - Encodes out of Adobe Premiere Pro are about twice as fast on the new iMac
                  - HD renders out of Adobe After Effects (both H.264 and Quicktime Animation) are about twice as fast on the new iMac
Other tests
                  - We have downloaded a trial version of AE CS6 and have gotten similar results (SD renders are slower on the new iMac than our older MacPros).
Does anyone have an idea what is going on here? Is there some way that the operating system, hardware, or Adobe software treat these files differently so that standard definition renders would be much slower than a 5-year old Mac Pro? Considering our new iMac has far superior processors and memory, we are not surprised that our HD renders are much faster now on our new machine. But we are just baffled on how it could be performing worse on SD exports.

I am having the exact same problem. I purchased an Imac and it was deliverd last week. I installed CS6 Production premium and went to work in after effects on a project that rendered very slow on my 2011 macbook pro 2.2 quad core I7 with 8gb DDR3 ram and an intel HD 3000 512 MB.
My new Imac has the exact same specs as yours and I figured it would fly through the render, but in Premiere and AE the results are the same, my macbook pro is equaling and even surpassing the speed of the render time.
I am very frusterated that the preformance is like this. If someone has answers please pass them on.

Video rendering extreemly slow or just halts

Being playing with video a bit since I bought a Sony RX100 III. Other than the well known problem with Dolby audio I find that rendering of video clips in Photoshop CC is very hit or miss. Sometimes the clip renders (very slowly if many adjustments have been made) or a rotating disc appears and nothing at all happens, task manager shows some activity but not nearly as mutch as when rendering is happening properly - the program seems to be in an infinite loop. My Windows 8.1 machine is reasonably powerful, if I use DaVinci Resolve Lite (if you think Photoshop has a steep learning curve try Resolve!!!) then even with quite complex edits clips render at around real time (25fps). Something is clearly wrong with the video rendering routine in Photoshop which is a pity as I only want to do the occasional bit of video editing and rendering and certainly don't want to pay for a dedicated video editing tool or invest hours of time learning Resolve (the Lite version is, amazingly, a free download).
Am I missing something? Do others find Photoshop video rendering flakey? Is there a work round for this problem?

I do not do video. However i did take a few clips with my Canon 1D Mark 4 it captures 1920x1080 frames and audio. The latgest clip I have is only like two minuets long. Video captured is format .MOV and the files tend to be very large. 300MB+ per minute. So I thought let see what Photoshop CC 2014 does rendering it to mp4. Render seem to be threaded so the more processors cores you have the better off your are. I have two slow 2GH 6 core xeons in my work station soe 24 threads were used. It took CC 2014 just under 3 minuets to rendet the video went from 733MB to 380MB around 1/2 size and bite rate the mp4 is.

Best Video Drivers For iMac G5 PPC

Ok now that the debacle caused by the ATI Drivers is over, Is there a recommended driver which provides the best results (ie. Fast, High Quality, Low Resourse) I seem to remember downloading one which enahnced Quartz (long time ago) I also recently came across drivers from ATI (Circa 2005) ATI Displays 4.5.7 and ATIccelerator II 1.0.6b which appeared to be improvements. Any suggestions?

I do not have the iMac G5.
My assumption is that your G5 has a hardware problem with video circuitry. I'd assume in safemode the software is doing the video rendering where as in a normal boot the hardware does the video rendering. In normal mode bad hardware means no workie.
You did a clean install, I assume. The software is good! Your machine worked before with this software. All points to a hardware problem.
It is quit clever of Apple to get your machine working using safemode drivers.
Software problems can be strange. Never hurts to try, but the chances of success are infinitely near zero.

Video Rendering Question using Premiere Elements 11 and/or Adobe Premiere

The video Rendering /encoding process can take hours even on an I5 processor.
It seems like this has to be done, redone and done again during the editing process.
If I purchase a camera which supports AVCHD 2.0 - does that mean that the encoding process altogether goes away, so that content is able to be transfered natively to the end media and so that I reduce my burn time to a BluRay Disc, using for example, Adobe Premiere Elements 11 or Full Fledged Adobe Premiere, or Sony's Vegas ?
Newbie to Video Editing.

AVCHD 2.0 only means that the camera can also record 1080p/60, which was previously not part of the AVCHD specification and still is not part of the Blu-ray spec. It's most useful for smooth slow motion effects.
Anything you add to Premiere Pro will need to be transcoded for Blu-ray, no way around that.

Premiere Pro CC very slow on brand new iMac

Hi
We have bought a new iMac, set up the Creative Cloud and downloaded Premiere Pro.
We've started a few new projects on this machine and whenever we play them back, the video always freezes on a frame whilst the audio carries on playing. When pausing the playback for the visual to catch up, Premiere takes a while to respond to the pause action.
We've tried changing the video renderer to Open CL, CUDA and Software only and still no luck.
The computer specs are:
Mac OS X Yosemite 10.10.1
3.5 GHz Intel Core i7
16GB 1600 MHz DDR3
NVIDIA GeForce GTX 780M 4096MB
Premiere Pro CC 8.2.0
Any suggestions are more than welcome and I will respond with the results.
If you require anymore information then please ask and I will be happy to supply you with the details.
Thank you for your time and help in advance.

Thanks, Jason, that's what I was wondering about. Generally, people post to forums when they have problems.
Yep. That's usually what happens. My review will be centered around my usual "benchmark" of editing 2 AVCHD inputs, one PiP'd into the other, synced with an external audio source, and then exported to an h.264 MP4. CC on my current Mac Pro (modified dual 3.46Ghz Xeon, 48G, nVidia GTX570) takes that task about 1/2t, if t = length of video. Which is pretty damned good. I'm hoping the dual GPUs will help scale that export task down a bit more. I don't expect it to hit 1/4t, but.. hey, maybe I'll be surprised?
I make about 60% of my living from Pr, and the rest from Ae and other apps (mostly Adobe).
Given the lack of CUDA, at the moment, I don't expect the new Mac Pro to be a stellar performer with Ae specifically. I assume that Adobe is working on OpenCL'ing Ae as much as they possibly can. But from what I understand, it ain't there yet.
(I'd need a TB monitor and PCI extender, too).
I can understand the need for the PCI extender, but why the TB monitor? I'd in no way even remotely consider one of those, just given how ridiculously priced they are. There's no need for one. Does your display have a DP input? You're all set. No? It has HDMI instead? Still all set. It's dual-linked DVI that becomes problematic.

Hi Babowa and Apple:
Thanks for helping me.   Here is my workflow:
I store any file that I save onto my external drives so that I don't fill up my main hard drive.....( I label each external hard drive by year + alpha, such as 14a, 14b etc.) Is that a problem?   Any suggestions?
I know iMovie works from the main iMac HD and therefore needs to find the file that I want in the external drive, such as when I "import" a file from an external such as 14a into iMovie that has been previously downloaded onto the external 14a (I download all SD cards & tapes to externals)......and it sounds like you're saying that is causing iMovie problems because the file is not so easily accessible for iMovie?
I assume that iMovie processes the file that I have "imported" into an "iMovie Event" on my iMac HD. I label that version as say "NLGE 3000E" for my 3000th movie, Event version, "events" that is always rough.
After I have imported media as an event and have labeled an event, "NLGE 3000E," then I go to "new movie" that I assume is a "project".....and I label that version "NLGE 3000P1"...."P" for "project" and "1" for the first edition....also to help me keep track of where my movies go.   I focus on "Projects" then when editing ...and watch which edition I am editing and which edition appears where.
I learned that I need to "share" all movies from "Projects" to save......and store my final versions on my external drive, 14a (eg) so that I am sure that I have a retrievable copy.   I try to share to YouTube from iMovie and succeeded 1/10 tries.
Evidently a movie is not saved unless it is in "theater"?
Please see next "reply" for other comments about retrieval.
Thanks.

Adobe Photoshop CS6 Very Slow On Rendering Type

I have a notebook with specification as mentioned below :
Lenovo Ideapad Y470P
2nd generation Intel Core i7-2670QM Processor( 2.2GHz 1333MHz 6MB)
Windows 7 Ultimate x64
AMD Radeon HD 7690 2GB
8.0GB PC3-10600 DDR3 SDRAM 1333 MHz
750GB 5400
I'm using Adobe Photoshop CS6 (64 Bit) for doing my job.
Right now, i have a task to create a banner with dimension 800 x 900 Centimeters with Resolution 300 DPI and Color Mode RGB 16 Bit.
The file size when blank is about 56.1 GB.
The problem is, when i add some text with Horizontal Type Tool and click on the Move Tool, the Rendering Type screen show up and take a very very long time to finished.
I have made some configurations to my Photoshop that i found on Adobe Forum, but the problem still persisted.
Some configurations that i've made is :
- Turn off the Automatically Save Recovery Information
- Set Maximize PSD and PSB File Compatibility to Ask
- Set the Memory Usage to 95%
- Set the Cache Levels to 8 and Cache Tile Size to 1024K
- Set the Graphics Advanced Settings to Drawing Mode Advanced, and Check the option Use Graphics Processor To Accelerate Computation, and Uncheck the option Anti-Alias and 30 Bit Display
- Set the Scratch Disk to another partition ( C:System D:PageFile E:Data F:Scratch Disk)
And after all of that configuration, my Photoshop still slow when Rendering Type.
Could you give me some tips to solve my problem?
Thanks

300 ppi for a banner that size is categorically not normal. Guaranteed.
Get specific instructions from the shop that is going to print it.
You keep confusing ppi with dpi. The resolution of an image file really is expressed in ppi, pixels per inch, not "dpi" which is dots per inch. The precise terminology is as follows:
DPI = Dots per inch = units used to measure the resolution of a printer
LPI = Lines per inch = The offset printing 'lines' or dots per inch in a halftone or line screen.
PPI = Pixels per inch = the number of pixels per inch in screen/scanner file terms.
Here's a link to a discussion that may interest you:
http://graphicdesign.stackexchange.com/questions/487/what-ppi-should-a-large-format-artwor k-for-print-be-done-at
It includes the following chart and subsequent comments :
"The rule of thumb is that we need 1.5 to 2 times the LPI in PPI to get acceptable results.
"Viewing Distance   Present Study
20 feet    greater than 10 LPI
18 feet    18.75 LPI or greater
16 feet    18.75 LPI or greater
14 feet    37.5 LPI or greater
12 feet    37.5 LPI or greater
10 feet    50 LPI or greater
8 feet     65 LPI or greater
6 feet     85 LPI or greater
4 feet     100 LPI or greater
2 feet     133 LPI or greater
1 foot     150 LPI or greater
6 inches   150 LPI or greater
"Presumably, for a banner 3m x 5m, you'd be standing at a minimum of, say, 10 feet. (Just eyeballing the wall here.) So, by this table, you'll need 50 LPI minimum. That would mean your raster graphics should be about 100 PPI, or 75 PPI at 12-14 feet. Considering that and the fact that 2x LPI is pretty conservative for reproducing fidelity (often 1.5xLPI is "enough"), this agrees with [the given] advice of 75 PPI being acceptable."
Talk to your printer. I suspect they will want a file at under 75 ppi, or even much less. Follow the printer's advice/request.

Help please! imac is completely full, FPC wont let me render! I'm a video editor and have over 70 gb worth of videos on the imac which all need to be kept but now beloved imac is full, only had it for 5 months! need external hard drive every 5 months??

FPC wont let me render! I'm a video editor and have over 70 gb worth of videos on the imac which all need to be kept for various clients/backup/original versons but now beloved imac is full, only had it for 5 months! Will Ineed external hard drive every 5 months?? This can't be I've already resorted to getting rid of unsed applications such as garage band, iTunes,address book ect. I've trashed everything I could. what next ???
My video files are massive, converting them to a different format doesn't reduce the size of them it just turns them into mp4 or apple pro res ect
This iMac is for work only so there's no pictures, no music, no conacts, no messenger, no games, nonothing but videos!!

Have a look at this: http://grandperspectiv.sourceforge.net/
It will show you exactly what is taking up all of your space.
You also may want to consider some kind of external storage just for your video projects.

Why do i need three? - Google Talk Plugin, Google talk plugin video renderer and Google talk plugin video accelerator?

When I check my plugins, the following three, very closely related (in my mind) plugins are listed, and the "Renderer" still shows "Research" when checking to see if it is Up-To-Date. It seems to me I don't need all three. I tried removing the Renderer (yes, I know how to do that safely), but Google seems to continue to reinstall it (with one or both of the other two...?)...I'll ask this on a Google Forum too, since it's their product, but wondered if anyone has any insight. I obsess about plugins that need "Research" - Thanks!
Google Talk Plugin Video Accelerator version:0.1.44.24
Google Talk Plugin Version 3.15.2.12038
Google Talk Plugin Video Renderer Version 3.15.2.12038

Went to Google Talk Help and found advice to remove the "googletalkplugin_port file on [my] computer."
http://support.google.com/chat/bin/static.py?hl=en&page=known_issues.cs ... and click "Voice and video plug-in unrecognized" under "Currently Known Issues"....
Now, the only Google Talk plugin I have in Firefox is
Google Talk Plugin Video Renderer
Version 3.15.2.12038
...but it does indeed remain "Unrecognized" by Mozilla/Firefox...

Photoshop CC Video Rendering

Hi, does the Adobe media Encoder uses CUDA for video rendering? Problem is, when i render video in PS CC, it takes up to 20-30 minutes for a 30sec. clip, only work done was camera Raw filter. CPU ia at 88%, GPU 0% due rendering.

As you see I have latest driver installed so I don't belive this is the problem - something just crashes in photoshop (after the latest update something just don't work anymore).
Like sometimes i can make simpel GIF and sometimes I'm not abel to do same thing with same file cause save for web window play/stop buttons are disabled.
I actually managed to to ger transparent cubes out of it (all 101 of them)- I added replaced illumination texture on each side matchin gwith the material texture,
but now there is no shadows on it beacuse it's basically a light bulb. I belive I just have to doodle with it a bit more and maybe
i manage to get it right (but save for WEB window play/stop buttons still don't work).
I belive there is something to do with photoshop updatet cause i have done some stuff before and it worked well then:

I need to get back individually erased photos and videos from my iMac with no backups to help. Please help

i need to get back individually erased photos and videos from my iMac with no backups to help. this is an attempt to consolidate all my data, new and old so I can uninstall Maverick and put Mountain Lion back on my iMac. Any help would be greatly appreciated.

If the files have been overwritten and you don't have a backup, they're gone.
If they have not been overwritten, then there are third-party apps (for example Techtool Pro 7 ) with data recovery functions that might be able to retrieve some or all of your files.
Backing up is good.

Output iPad video to 27" iMac using iPad VGA adaptor?

Hi, I was wondering is it possible to Output iPad video to 27" iMac as an external monitor using iPad VGA adaptor?
Thx.

No. The VGA adaptor is an analog connection and the only inputs are digital Mini Display / Thunderbolt ports depending on your model. It maybe possible with a conversion box of some sort or maybe trying an HDMI to mini display port cable ($44.95) and an iPad 2. The 27' should be able to be used as a second display but the 21 is not. If you have the iPad 2, pick up the cable and the HDMI adapter and try it out. If not, return the cables within two weeks.
