Preview very choppy over wireless

I just had to force shutdown my macbook for the first time earlier today after trying to open a large tif over the wireless network. Fair enough that file was painfully large. I squashed it to a 5 meg jpeg and at least was able to load it after a longer delay than i'd hope for such a small file (versus copying it to a local hdd).
I tried actually moving around the image, zooming in and am dissapointed to see that at 100% view it pauses as i try to scroll around the image. The CPUs aren't even breaking a sweat, i can only assume bizarely that its not cached the file locally and is trying to get it over the network all the time.
Anyone comment on this? By forum title i assumed that this was the forum to use.
Otherwise i love preview, can't it be a bit smarter when working with files that aren't local? I think i'll resort to viewing the files on my browser, which works fine.. initial delay and then no problem at all. But i do think preview should cope with this too.

Please give your full system specifications, what computer, what drives, what camera or deck, how everything's connected, what settings are on the media, what settings you're using in Final Cut, and finally what version of the software, of the OS, and of QuickTime you are using.

Timeline playing back very choppy over multiformat video.

Hi Guys,
I am editing some behind the scenes footage for a movie our studio is making. A lot of the media has come from different sources. Some red, some mpeg4 etc. The Mac i am using is a Quad Core Mac Pro... technically it should be powerful enough to play over all these fine. But even when everything is rendered, it is very choppy. So much so, that to check my audio is in synch for some of the action shots, i have to export it as a Quicktime and play it back and check it that way.
Now i have tried RT in unlimited and safe... but it still happens. Does anyone have any possible solutions at all?
Any help would be much appreciated,
thanks in advance.

My 2nd generation Airport Extreme very slow via wireless (5 and belows mbps) wired over 20. Please help! What could it be?

It is very possible that you may have some form of Wi-Fi interference nearby that is preventing your AEBSn from providing a clean RF signal on the 2.4 GHz band.
I suggest you perform a simple site survey, using utilities like iStumbler, or AirRadar to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible.

My iTunes is very choppy when watching videos

My iTunes is very choppy when watching videos. I just dowloaded a couple shows and it stops then goes really fast when it play's. Anyway to fix this?

Yes! I have the exact same issue. So I tried some things.
I am on Uvese (via wifi) and was trying to update the apps on my PC via itunes. Taking FOREVER. So i tired it directly from my iPhone 6 via wifi - same issue. Then I turned off wifi on the iPhone and updated over (ATT) LTE. That worked great. I am thinking it is a Uverse/ATT issue at this point.

I have Adobe Elements 9 and I used to be able to export HD 1080p videos with no issue. But recently, when I export using H.264 MPEG or MPEG 2, which I normally used, the high resolution videos come out very choppy. How can i fix this?

mr
Are you running the 9.0.1 Update of the program and on what computer operating system is it running?
Is your video card/graphics card driver up to date according to the manufacturer of the card?
Is your computer optimized, including maintenance of pile ups of preview files, conformed audio files, and conformed video files?
Do you have the latest version of QuickTime installed on your computer with Premiere Elements 9.0/9.0.1?
What are your project settings and what are the properties of your source media? When you say that "used to be able to export...." is that on the same computer, same brand/model/settings for the camera recording the video now in use, same Premiere Elements 9.0/9.0.1?
Where player are you using for the playback of these exports?
Please give us more details on the size of the projects (then and now) as well as details of the customized export settings in your Share/Computer/ route. Premiere Elements 9.0/9.0.1 is only a 32 bit application running in 32 bit or 64 bit system. Not sure if computer resources might be taxed more so now than before.
More later.

Scrolling PDFs in Preview is choppy

Scrolling, even the smallest PDFs, in Preview using the trackpad (swiping a la iPad) is very choppy.
Even if I'm swiping very slowly, it pretends that I'm not moving my fingers at all, and then suddenly it jumps down half a page.
I did not have this issue with Mac OS 10.9, this issue only started in 10.10 Yosemite.

Thanks...I guess I could have figured that out on my own. To my defense, however, I realized that the document I was attempting to do that to is password protected - a situation that doesn't, understandability, permit this. I tried it on an unprotected version and it worked.
Thanks again.

Verizon iPhone 5, 64GB black - is anyone having issues with a very choppy conversation while talking on the phone? Both my wife and I have the same phones and are both having the same issue. We can only hear every other word of the person we are talking to. This happens at home, on the road and in the downtown area while calling both cellphones and landlines. It is intermittent, so we don't know exactly when it will reoccur. Absolutely no problem with data. The data speed is great.

had some old movies from reel to reel on a vcr. i converted these to mp4 format using pinnacle video capture, quality was not great but it was decent enough on my computer. when i placed these on my ipad it was much worse and very choppy. i have handbrake and thought i could maybe change the movie so i could play it on ipad but dont know what dimensions or framerate etc. currently the movie on the computer is in 640 x 480 mpeg 4 aac. thanks derek

Jon,
What Julianne said at first about re-linking made perfect sense and I followed it easily, had actually already been there. But in my situation now, it didn't have any effect. The directory of folders which had already been added were still just as they were, and the outstanding balance are not in the desired position. And the folders which had been brought in earlier today when I clicked "synchronize folder", were still missing all the metadata.
Maybe this means I need to start over, and I'm fine about doing that that, but I don't know what it takes to accomplish that. I'm concerned now that any changes I make out of guesswork could only make the problem harder to resolve. It just feels to me like something I did at the beginning just wasn't right, and now it's a tangle.
Can you advise?
Thanks,
Gary

IChat to PC... video/audio very choppy on my end, good on their end???

I'm using an iMac G5 2GHz with OS 10.4.6 and the person I'm connecting with uses a 4 year old Windows machine at 400MHz. She is telling me that using iChat on my end and AIM 5.9 on her end... my audio/video seems pretty good on her end, but the audio/video I see of her is very, very choppy with a/v sync problems and to the point it's essentially unusable. We tried iVisit as well and what she sees/hears is good on her end with that and a lot better on my end than iChat but some mild a/v sync problems and slight choppiness, though much more usable. Is her old/slow computer likely the culprit here? I'm assuming that the 400MHz processor is likely not able to churn fast enough to get good audio/video out, and can't really be overcome by high speed internet. Is this likely the case?

HI Joshua,
Get her to do this.
Start a chat.
She shoul see that your incoming Vid is infact the front one of two tabs.
She should click on the rear one to bring it to the front.
It is her preview.
Next should look to the right where a small squarish icon has appeared.
She should click on this
Next a slider will have come up.
She should slide this to the left.
At this point it is worth you having the Connection Doctor open(in the Video menu)
You should see that her frame rate and Bit rate goes up.
Th eprocess actually reduces the quality of the video she is sending. As a conseqence there is not so much data in every frame and her processor can pass more frames and the video will look smoother.
You may find her Audio also improves.
10 frames a sec is about what you should be expecting form a PC. If you get more and the picture is fine otherwise consider it a bonus.

MDNS unreliable over wireless

mDNS isn't working on my laptop if I use wireless - which breaks Airplay (and quite a few other things besides!).
So far I've established that:
mDNS queries ARE sent out over wireless.
Replies are sent out over wireless just fine (tested by using a Linux box as the access point and running tcpdump on the wireless interface).
But the replies aren't seen by the wireless adaptor on the laptop (tested with tcpdump on wireless interface on the laptop).
This is an intermittent fault. It doesn't happen every single time, but it does happen often enough to be very annoying.

If any firewall is in use, disable it.

Time capsule over wireless

Can I plug my Time Capsule drive (Passport) into Airport Extreme USB port to back up over wireless network? How?

Connect the drive to the USB port on the AirPort Extreme
Open System Preferences (gear icon on the dock)
Open Time Machine
Click Select Disk
Click the name of the drive to highlight it
(If the drive does not appear, you are receiving a message that Time Machine does not want to do this....best to stop at this point)
Click Use for Backup
Time Machine will make a new complete copy of your Mac, so using wireless, this is going to take a very long time.
Your "old" Time Machine backups will be OK, but you will not be able to use them with the drive connected to the AirPort Extreme.

Videoconference H.323 over Wireless

Hi everyone
We are looking at the possible creation of a "video only" network for the transport of our clients H.323 videoconferencing traffic throughout our community. Does anyone have any experience transporting H.323 video over wireless networks? Any success?
Specifically we would like to create a central hub site located in the city which all the edge videoconferencing units connect to. We would put an Aironet 1200 centrally located and 1200's at each client site. The radius around the hub is about 5km. All buildings are line of sight. One client is at the 5km mark and will be the main jump point to the surrounding communities where they already have all the IP based videoconferencing systems sitting on their WAN.
I am not sure if the 1200 with the 5Ghz modules are capable of this distance at a reasonable speed? And have not been able to find someone that had tried H.323 video over a half duplex link? Any thoughts would be greatly appreciated!
Thanks,
Ken

We have obtained exceptional video and audio performance with a H.323 Video Conference solution using two Polycom Veiwstations at 768Kbps over an 802.11b (11Mbps) network using 350's, however the key to this type of installation is very high signal to noise and narrow beam point to point links (in areas with lots of public traffic).
The project was for a video conference link between a remand facility and a local courthouse. They found that the costs of transporting prisoners between the remand center and courthouse and the waiting times were far more costly than the implementation of a videoconference facility to do simple remand hearings.
The Courthouse and Remand Center are aproximately 8km distance but have no direct line of sight, so we encorporated a central repeater site. Initially this central site was equiped with an Omni 180deg 15dBi antenna and a 350 series bridge, the two remote sites were equiped with 13dBi 30deg yagi antennas directed towards the central site. We had signal levels of between 13-18 dB signal to noise but found that the performance was not adequate to carry video traffic at sustained speeds. Since the wireless network is half duplex the addition of the repeater site makes the end to end network act like a 'quarter duplex' as it were. (two seperate legs each having to wait for the other to finish before communicating).
Before we were sucessful we tried a number of senarios, including the placement of a video bridge at the central location which enhance the store and forward capability of the video and audio data above that of the 350's data buffers at the cost of a bit of latency. In the end we needed to add a second bridge, to separate the two legs with non-overlapping channels, in the central site and replacing the Omni with two Yagi on the two seperate bridges (the bridges linked via 10Mbps switch) just to get the system up and running by the deadline. A lot of our greif we later determind was due to other wireless networks in the vacinity (keep an eye on carrier tests at all locations durring the installation, and use narrower beam antenna's where aplicable) this coupled with the 'quarter duplex' senario greatly hampered the situation.
In hind site we would definately use as narrow a beam width high gain antenna as possible, like a parabolic dish to point at the central site, eliminating much of the sorounding noise. and try and keep the S/N as high as possible as well.
-We suggest using a well grounded nema enclosure mounted as close to the antenna as possible to eliminate loss on coaxial cabling.
-Pay the extra money for higher quality coax, coax can add as much as 20dB/100ft. attenuation depending on the quality of cable.
-the use of signal splitter/combiners with multiple narrow beam high gain antenna's and amplifiers to increase your power output and receive gain (taking note of maximum ERP allowances in your area of course ;) instead of an omni or sector antenna. This will reduce interference from other radio networks in the vacinity.
These precautions hold true for any installation but considerably so for Full Duplex Constant Bit Rate applications being used over a half duplex system like Video Conferencing which requires low and stable latency.
Feel free to contact me with particular questions in regards to your project.

Image processing over wireless

Hi,
One of our subsidaries has a setup where continuous video stream is generated from certain application servers processing real time image processing.
The setup goes this way; 3 PC's which run these image processing & are connected to a 3750G switch.
This switch is uplinked to an access point which then carries all these over wireless to the image processing main server.
About two weeks ago, when they tested this ,all 3 PC's had issues running together when operators viewed/worked upon the images on them.
When either one or two of them is turned off, the rest works fine with no disturbance( intermediate stop & start of images ).
Please help with suggestions on what could be the cause. I suspect bandwidth, but since this doesn't cover any WAN links, i doubt that bandwidth is actually the problem.
Thanks in advance.

It depends. QoS will help if your having congestion on the wired side. WMM QoS will help for over the air. I would look at the switch port and see if you see drops on both the map and rap side. You might just be over utilizing the backhaul. Remember that it is half duplex link so that can be an issue also. I had an install with regular AP's and 3gb video uploads within 30 minutes and the only way to achieve that is only allowing 4-5 clients per AP. the testing you have done seems to show that the max you can do over that link is 2. How much other traffic is using the wireless. Maybe try to isolate those traffic on a separate RAP/MAP pair using AP Groups.

Hello
I don't know who to complain to as you do not appear to have a complaints department, despite searching the web, I trust you can pass this to relevant department for action, as I'm very angry over my recent repair.
Following my issue relating to a blank screen 2 weeks ago, your advisor arranged for my iMac to collected by Amsys, for repair and return, this was done and it was returned to me last Tuesday, onWednesday I set up my iMac again and instantly realised I had problems, much worse than before. I called Amsys to inform them of the issue of the computer being very very slow and unable to open iPhoto and pages, and document listing would not show up, plus I had no sound on the mac.They informed me that they had only replaced the video card and what they had done would have not affected the computers performance. He suggested I reinstall OSX again which I did, but this made no difference to the programs, so I called you.
Your technician on the phone was very good as they have always been, and made an appointment for me to go into the Milton Keynes Apple store the next day at 1 pm, which I did.
The gentleman on the Genius Bar was very good and was able to run tests on the iMac in my presence, and diagnosed immediately an issue with the sound problem, and advised me that this could not be fixed while I wait and I would need to leave it for repair. I made him aware of the previous repair, and he was able to see via your system, the list of logged issues I have had with this since purchasing in September 2012. I'm sure you can see from the way you record all calls and issues the problems I have had.
Today I called to ask if my iMac would soon be ready for collection, I was told the repairs had been completed and it was being tested. However to my dismay, I learned of another serious issue relating to the repair carried out by Amsys. I was informed that 6 screws were missing from the the iMac internally, which caused me much distress and concern, they also told me I had to wait even longer as the screws had to be ordered and installed on arrival before I could collect it.
My issues here are: I trusted the Amsys repairer as it was arranged and recommend by you, it is very evident they are not competent to repair, as they have caused more problems with my iMac on its return, despite enclosing a checklist, fully ticked showing everything working well, it clearly wasn't ! Plus the issue of missing parts (screws) during the repair, I have already expressed my disgust with Amsys, by email and had a response, within the hour, apologising and told me they were looking into this.
This where I stand on this, I have not had my iMac for almost two weeks and I do not know when I will get it back. I'm also very worried about what other damage has been caused by Amsys and the quality of my iMac now. I want to know what you, Apple is going to do about this ? I have already been very inconvenienced by this and until now I have been a very loyal apple customer with 2 iPads, and 4 iPhones in our household, not to mention the iMac.
I feel I have been very let down by this experience, on my iMac, which cost a lot of money, I have also lost a lot of money with lost work and unable to carry out my business without it, and I will be seeking compensation.
I trust you will take this complaint seriously and pass it to the relevant department for action.
Yours sincerely
Des Withey
