Enterprise wireless Video quality issues

Hello
My primary wireless subnet passes traffic through a Websense device. I Alway's get many "buffering delays" and video quality is substandard.
Watching video's from Youtube is frustrating on the Primary wireless.
              QoS for Primary is set to Silver
               Wan link is 100M and is usually running at 80%
I als have a Guest network, that uses a seperate Cable WAN link. Traffic does not currently pass thru Websense and I don't have buffering problerms.
I do get substandard video quality on this wireless network as well.
             QOS for Guest is set to Bronze
              WAN link in 50M/10M
I employ WISM's and Cisco 5508 controllers
AP's are mostly Cisco 1131, 1142, & 1242 models
      upgrading my AP's is not a financial option at this time
What else can I look at to improve the Video quality of y wireless networks?

Simple answer is to implement QoS in your wireless for voice/video.
There are lots of work to do. Refer this design document as a guide.
Real-Time Traffic over Wireless LAN Solution Reference Network Design Guide
In high level here are some task you can independantly check & configure if it is not align to recommended design guides.
1. end to end QoS configured on your wired switch network. Below blog post may give some help
http://mrncciew.com/2012/11/26/375035602960-wired-qos/
2. WLC management to be on tagged vlan.(see this TechNote)
3. If all AP are local mode, then trust DSCP on switchports where AP connected.
http://mrncciew.com/2013/02/24/best-practice-qos-config/
4. Trust CoS on WLC connected switchports
5. Video traffic to be classified (AF41) and allocate bandwidth across your network.
6. WLAN QoS profile to be configured as Gold or Platinum
http://mrncciew.com/2012/12/02/understanding-wireless-qos-part-3/
7. Plan your wireless to have around 10 clients per AP if they are using Video.
8. If you are using Multicast for video streaming, then you need to enable video stream feature as well.

Did Apple fix the video quality issue in iMovie '09?

I am a casual video editor and iMovie 08 had the perfect user experience / functionality for what I want to do.
However, the known video quality issue (throwing away interlaced scan lines) made the result unacceptable since I archive our family video on DVDs. I have been forced to use iMovie HD for that reason. I have tried tricks such as converting the original DV files to AIF and deinterlace prior to import into iMovie08 but that did not seem to work either.
So does anyone know if Apple fixed the video quality issue in iMovie '09.
MESSAGE TO APPLE IF YOU ARE LISTENING:
Please fix the video quality in iMovie09 if not already. Yes, the quality is ok for YouTube or Internet video but for those of us who want simple editing to archive our family video we cannot accept poor video quality. Dropping an interlace field effectively halves the vertical resolution. Thank you.

Please explain this in more detail when you say Adaptive Deinterlacer. Are you talking about another program? If so, what program and what are the specific steps.
Also, sounds like you are recommending imovie09. By saying to do the above, are you saying imovie09 still causes you too loose significant quality like imovie08? Are you saying you can use imovie08 or imovie09 with these steps to get high quality video or just imovie09? I guess I just need more specifics on how you do what you are describing and how imovie09 fits into this versus imovie08. I joined this whole discussion trying to figure out if upgrading imovie09 made a difference regarding the whole quality issue. I know it has more features, but I am more concerned about he quality of the video right now. Thanks.

Canon Vixia HFM40 video quality issues in Premiere Elements 10

Hi,
I am trying to edit video from a Canon Vixia HFM40 camcorder in Adobe Premiere Elements 10 on a Mac, but the video playback and the exported video has quality issues. Playback is not smooth when there is a lot of movement in the picture. It looks similar to interlacing issues, but there are no horizontal lines when the video is paused. Any ideas on how to solve that would be be much appreciated.
Here are the specs:
Video Format (Canon's XFP mode):
- AVCDH MPEG-4 AVC/H.264
- Resolution: 1,920 x 1080
- Bitrate: 17 Mbps
- Frame rate: 60i or 30p (problem occurs in both instances)
- File extension: MTS
Workstation:
- Fall 2010 27" iMac, quad core 2.93 GHz Intel Core i7
- Mac OS X Lion 10.7.2
- 12 GB RAM
- Adobe Premiere Elements 10.0
Project Preset: AVCHD Full HD 1080i 30 (several other presets had the same result).
Thanks.
Ralph

OK, I've been doing some more research and I think I found the problem. The choppy picture is due to Premiere Elements and VLCs inability to properly de-interlace the 60i video. It gets played back in 30p, which does not create horizontal lines, but it is a lot more choppy than the native 60i, especially when there is a lot of movement in the picture.
I verified this theory by installing the latest VLC beta (from http://nightlies.videolan.org/) and playing back my source MTS file with De-Interlacing set to "On" and De-Interlacing Mode set to "yadif (2x)". Those settings did not work with the current official relase of VLC (1.1.12). The 1.2 VLC beta is not fully functional yet and I am not getting consistent results, but when I play that video several times, then after about 3 or 4 tries it plays back perfectly smooth, just like it is when playing back the native file from the camcorder connected to the HDTV via HDMI.
That also works with video exported from Premiere Elements 10 with preset AVCHD M2T - H264 1920 x 1080i 30.
The video is still choppy when played back in Premiere, but that does not really matter, since the output file produced by Premiere can be played back with VLC (assuming that the final build of VLC 1.2 can handle the files correctly).
-> Hunt: thank you again for your help.

Export DV Video Quality issue

I have a HDV project that looks great on the screen and when exported to DVD using quicktime, but the client needs it on DV tape. I'm exporting using Print to Tape via firewire to my Sony FX-1 camera using DV settings, but the video quality is awful. A moving logo that looks great on the screen is pixillated and shots that look good of computer screens are unreadable on the tape. Any specific suggestions for video output settings, rendering options, etc. would be most appreciated. Oh, and I am also trying to export the 16 x 9 video as optimized for 4 x 3: could that be part of my problem?
Thanks.

OK, help me out here: I don't want to pretend to know something I don't: This is a 30 second spot going to the Virginia PBS stations for the state Dept. of Education, which is my employer. The caption house the DOE uses will be putting the spot on Beta SP, as that is the format the stations want it in. I'm just trying to get it onto tape so that it looks as good as it does on my screen. I don't really know what anamorphic means, and I'm just getting started using Compressor. I've gotten to the point where the pixellation that was happening before is gone, but I'd like the spots to retain the 16x9 look I shot them in, so I was thinking letterboxing.
Any thoughts would be greatly appreciated, and the more detailed the instructions when using compressor the better. When I worked at a station there were other folks who helped me with this kind of thing, and I'm hoping to get a setting that works, create a profile for it, and move on.
Thanks to those of you who are being patient with me.

IMac 24" video quality issue (streaming and non)

I have searched the forums extensively and not found anything that quite matches the issue I'm currently having. If you know there's a previous thread with a solution please direct me there.
This issue first popped up when I tried to watch the season finale of 30 Rock on Hulu: the focal points of the scene weren't as sharp, everything in the background seemed seemed to pixelate intermittently and if there was any kind of motion, there was pixelation around that. I chalked it up to Hulu's new player, especially since anything else I watched on Hulu had all the same attributes.
Then, after taking a break from not using my Netflix, I noticed that anything I streamed on there did the same things. I checked my ISP download speed and it was 20mbps (way above the suggested amount for DVD-quality picture). It also seemed fishy that when streaming Netflix through my Xbox 360 (and the same router), everything looked beyond crisp.
The final straw came playing DVDs. I noticed some of that same degredation around motion that plagued the other two examples, although on a much smaller scale (my assumption being that the quality starts out much hire from a DVD source than streaming).
Has any one ever had this issue? The machine is not even 2 years old yet (Purchased March 2008).
Thanks in advance for any and all responses,
Leo

The general question of whether to use interlaced footage is a topic for another forum (e.g. the Video Lounge) but one thing to bear in mind when embedding video into PDFs is that it won't usually play at 1:1 pixel scale. Resampling will occur, and that can introduce visual effects.
You have two options to make the video play at '100% size' - either set the Rich Media Annotation to play in a floating window and define it to match the footage dimensions, or use a custom version of the videoPlayer widget that turns off scaling.

Itunes Video Quality issues and crash in Windows vista

When using itunes listening to music works great, however when i play music videos purchased from the store they keep on skiping and after a while itunes will close and a message from windows will appear saying the software stopped working. when the video is playing the sound is fine and plays quite happily in the background however the video freezes and jumps.

Have you tried this article:

Wireless voice quality issues with wlc 5508 7.0.98

Hi,
I am having random occurances of voice drops (one-way audio) during phone calls. WLC 5508 (7.0.98) , LAP1242AG (only G antenna present), and 7925G phones. coverage is excellent throughout the floor and its a confined office space. Its not happening always. I am seeing these logs , not sure if it is related. :
*apfReceiveTask: Feb 10 11:31:53.831: %RRM-3-RRM_LOGMSG: rrmChanUtils.c:290 RRM LOG: Airewave Director: Could not find valid channel lists for 802.11bg
*apfReceiveTask: Feb 10 11:31:33.356: %RRM-3-RRM_LOGMSG: rrmChanUtils.c:290 RRM LOG: Airewave Director: Could not find valid channel lists for 802.11bg
I have set DCA list to1,6 and 11. I tried disabling RRM and statically fixing the channels and power also. Still the issue is seen,
7925G firmware is 1.4.1
i tried to do linktest from the WLC to the phone, but link test is failed. linktest to a laptop works though. I have only mac filtering for the voice ssid.
any suggestions pls ?
regards
Joe

Hi Serge,
Thanks for the suggestions. I have taken care of all the settings. Problem is , the user is seated in his office cabin and using the 7925 and there is around 50db signal strength in his room from an AP which is just outside the cabin. And this doesnt occur often, when we go to check and make calls, everything is fine whereas the user says it happens sometimes in the morning, evening etc... randomly... where the fone goes blank while in a call.... since the problem never happens when we go to troubleshoot the issue, we really dont know what is going on. This is happening when calling PSTN.
AP's are not restarting and there is no logs indicating that. Wireless infrastructure looks very much OK cos there are other users who are not experiencing this problem and there is ample coverage all over the floor. I am baffled why only one user has this problem even when he is seated in his office cabin.
Tried changing phones also, but still remains.
Question : i tried to do a linktest from WLC to his phone, but it failed, while linktest to laptops are working fine. Does wlc linktest not working for wireless phones ?
regards
Joe

Inserted video quality issues

I created a video in Camtasia and produced a MP4 which I am trying to insert in Captivate. When inserted the video size is large. When rescaled the quality is poor. How do I fix? I tried producing different sizes in Camtasia to get a smaller video but still huge when inserted in Captivate

Did you remove the large video from the library or have a different file name?
I found the same happened, if you simply reimport the video and it is the same file name it takes it form the library, go to the library, select the file, right click and update.

Video Quality issue

I recently downloaded an .avi movie file from the internet. I then converted it to an mp4 using quicktime pro in order to decrease the file size. the quality afterwards is greatly diminished. i used the new h.264 codec and still the quality is lacking tremendously. should i convert it back to an .avi or have i ruined the file. i was thinking maybe the frame rate was off but i'm a newbie at this and need some guidance. Thanks so much
Ryan

Here is another way to look at it - you started with a lossy and maybe mediocre quality AVI.
If you start with a DV source and use H264 vs. say Sorenson or 3ivX you should get as good a copy that is a lot smaller or a better copy for the same file size. The codec is good and a lot of compression on a good source (DV) can still make impressive results - witness the HD gallery on QT site and see how good those files are vs. how enormous they'd be as HD DV.

Captivate Video Quality issues when post to YouTube

We are using Captivate 7 and I am creating training for the MS Dynamics CRM application.
I created a video demo selecting the application window as the screen size. When I replay the video in Captivate or when I publish to Adobe COnnect, the replay looks fine. When I publish to YouTube however the text on the screens I recorded is very blurry. How do I get a better result with the publishing to YouTube? .

I'd imagine Youtube would be better if you're targeting overseas. I'd have to believe that YouTube/Google has a more global delivery setup than the smaller Vimeo...so video may play back better overseas via YouTube than Vimeo.
Plus, integrating Vimeo video into Captivate may be more of a challenge...
On the other hand, maybe not. Can you integrate a Vimeo video using the Web Object? If so, that may give you MORE flexibility than the YouTube interaction object.
Additionally, I know you can setup private channels on Vimeo...so if you don't want your content visible to everyone, that may be a better option. Whether you can setup the URL in Captivate to access those private videos on Vimeo though, I'm unsure. I don't think that would be as possible/easy to do via the YouTube interaction widget...

Issues with video quality after editing in Premiere Elements. Please help!!!

I am having issues with the quality of video output from Premiere Elements. I tried to combine 4 videos clips that I took (all were crystal clear when viewed prior to combining them in Premiere Elements). The first clip is quite pixelated, the second has wavy lines running across it the whole time (recorded webinar), and the third clip looks crystal clear. (FYI...first clip and third clip were both taken using the exact same settings on my Canon) I am not very tech "savvy". I am guessing it has something to do with the way I saved or "shared" the video after editing? But I have NO IDEA what settings I need as I am not very "tech" savvy! I want to upload the finished product to Vimeo. I looked on Vimeo and followed instructions from a tutorial that a Premiere Elements user posted about how to save the best quality video for uploading to Vimeo, and the quality turned out FAR WORSE than the first time I saved it. Please help!!! Thanks so much!

Thanks for your response John! Do you think my issue may be due to the way I initially "set up" the project when I created a new project from the very beginning? I am operating on Premiere Elements 10, so I do not see an option for sharing online directly to vimeo....only facebook and Youtube. I am combining 4 video clips. 3 of the 4 clips were shot on my Canon EOS 60D, and 1 of the video clips was a recording of a PowerPoint based webinar that we did via Meeting Burner (meetingburner.com). Since I am combining more than 1 video format, is it likely that I will run into quality issues? The strange thing was that 2 of the clips shot with my Canon showed up blurry after exporting/sharing my final video, but one of them was still crystal clear. This doesn't make any sense to me since I did not change any settings on my Canon. I didn't see any specific tutorials on setting up the project to match the video from that list of Tutorial links.

Quality issues with inserted video file

Hello,
can anyone help me with a video problem in Captivate 6.1, please!
I’m currently working on a Captivate project where I need to include a movie file.
I have the same movie in two different formats .mov and .wmv, which are both looking just great when I watch them with any player on my Windows7 system or on the Mac of my colleagues.
When inserting the movie the encoding to .flv takes place by the Media Encoder, which also seems to be working just fine.
But when playing the project in Captivate, the inserted video shows such a bad quality, that I’m not able to use it like this.
I already have tried different things (inserted as event video or multi-slide synchronized video; changed the slide quality to high; encoded the movies to .f4v files with the Media Encoder; installed a new windows codec package) but nothing leads to an acceptable result.
Which settings do I need to change in Captivate/in the Media Encoder to receive a good video quality?
What else could I do to improve the quality of movies for Captivate projects?
Is there any minimum requirements for movies concerning file format, encoding, or anything else?
Thank you so much in advance for your help,
Sabine

Hello Varun,
thank you very much for your reply.
I tried unchecking the compression options, doesn’t help
I haven’t yet published the project, the problems occur already when playing the project in Captivate.
The project resolution is 1280x720.
The resolution of the .mov-file of the video is 1920x1080 (12000Kbps, if this information is any helpful…)
The resolution of the .wmv-file of the video is 1280x720 (3000Kbps…)
Maybe the problem occurs already during encoding, the .flv that is created by the Media Encoder doesn’t look that good anymore, I just played it separately (not in a Captivate project).
Are there any settings I could check for the Media Encoder?
Thanks,
Sabine

MacMini - LG 32" (32LB75) Problem - Poor video quality and now no picture.

Hi there, apologies for the length of this post....
I purchased a mac mini 1.8Ghz with 2Gb RAM yesterday with a wireless keyboard and mouse and hooked it up to my 32" LG 32LB75 using VGA. On startup the display looked ok, I managed to click through the various Leopard initialisations. I bought the machine for use as a front room media player for mainly DivX movies and the occasional bit of music.
Once I had installed the DivX codec I opened a DivX file in Quicktime and selected "full screen mode." As soon as the movie started I became quite disappointed. The picture quality was quite pixelated ("noisy") and certainly not as good as when I play the same movie file from my old dell PC on the same LG tv (the dell PC has a 64Mb PCI radeon 7000 which connects to the tv using the same VGA port as the mac).
Anyway just to give the mac a fair go I thought I would try out some genuine quicktime video samples from the itunes store (this time viewed from front row)....again not brilliant.
So I thought I would investigate the screen resolution to see if I could improve things. It appeared the resolution was set to 1900 by 1200ish I say "ish" because I can't remember exactly. I then attempted to reduce the resolution and eventually I settled on one that looked quite clear with the font size big enough to be easily read. Again I tried the movie and there wasn't much (if any improvement). Whilst changing resolutions the screen would go blank for a few seconds but on one particular setting (can't remember exact numbers) the display went blank and never came back. The tv now just displays "no signal".
I despaired and connected the mac to a 17" Iiyama montior that I use with a PC and it worked ok. However each time I tried to "hot swap" back to the television I would end up with no picture.
I'm really disappointed because everything else about the mac I really like. Particularly the remote for frontrow which is precisely what I wanted it for. The problem is I've spent over £500 and now seem to have a lesser quality picture than I had to begin with (ignoring for the moment that I don't have any picture!!)
Anyway my questions are these, answers to any or all most appreciated.
1) what is the easiest way to get my mini to start displaying on my tv again?
2) what would the optimum resolution be? My television mentions 1366 x 768 in the manual
3) If the mini doesn't offer this resolution in the pick list is it advisable to "force it" using some alternative software (ie 3dexpress.de)?
4) Is the video quality affected by the software player? ie would VLC give better picture with DivX over quicktime/itunes/front row?
5) How likely is it that the video resolution of my new mac mini isn't "as good" as my old dell machine with its PCI graphics card?
6) Finally if I don't get results as good as my existing PC setup, how accomodating are apple with refunds? I bought it from a UK high-street apple store. The back of the receipt mentions a "14 day not satisfied" return policy but then goes on to say something about being "unopened"...which seems a little confusing. Ie how do you know if you're satisfied until you've actually used it?

Hi there
the solution was to remove the various display config files in leopard and then restart the machine, this got my display back on the tv (albeit off centre). To fix the "off centre issue" I used the LG "auto correct" feature from the remote control "menu > screen" options.
The apple support site describes how to remove the affected leopard display files here http://support.apple.com/kb/TS2213?viewlocale=en_US As you will see their resolution consists of 2 main steps, the first one involves starting your machine in safe mode, if this doesn't work then you proceed to the second step where you remove the files using a terminal prompt.
I didn't bother with the first step mainly because I don't think I can start my mac in safe mode since my only keyboard is wireless (bluetooth). So I connected the mac mini to a 17" LCD monitor (which thankfully did display the video signal ok) and removed all the listed files using terminal. I then shut the mac down, swapped the VGA cable back to the LCD tv restarted the mac and it detected the tv and set a resolution that worked. I then very carefully reduced the resolution down to one that was recommended by my tv (1300ish.. x 768ish??).
At this point I was back to having an acceptable signal but still a little off centre. So I used the TV remote, pressed menu, went into screen options and chose "auto correct". Picture then filled the screen perfectly.
The problem seems to be, leopard lists a bunch of resolutions that it believes your tv/display can handle but it would appear that in fact some of these resolutions are not supported by your TV and if you choose one of these your signal disappears and you can't get it back.
I would still say that I'm not 100% convinced with the mac mini's onboard graphics (I have a 1.8GHz version). I'm going to download some HD content and see if that improves things, but certainly my existing DivX collection looked a little sharper and clearer and better coloured using my old dell PC with its radeon PCI card. But the difference in picture quality is outweighed by the convenience of its size and the font row interface. I might tinker with putting Windows Media Center on it one day, perhaps that might improve things.

How do I get good video quality?

I can't seem to get more then 20 fps and not so hot video out of iChat AV. With what should be pretty good connections, I still get stopping or pixelation at times, so I've been trying to isolate the issue.
Conferencing over an airport on an in-house system for a test, with 2.4 megs of pipe (showing in Connection Doctor; other tests show 10 megs up and down) using either iSight or a DV camera, I get 20 fps, no more. OS 10.5.3 on both sides, Quicktime 7.5 on both sides. Intel Duo 2Ghz with 1 Ghz ram on one side, G5 with 5 gigs of ram on the other. One way video chat. No other apps running. No other traffic on the Airport.
We're trying to use this for student "live shots" over the internet. The quality of the video frankly used to be a lot higher with earlier versions.
I don't get it. If it is possible to get 640 X 480, 30 fps out of this, I can't figure it out. Hopefully, one of you will know how to do it. Do I need to install Quicktime Pro? Is there some magic button or setting somewhere? (yes, i is set on LAN) Do I use another application that has low latency like iChat AV but better video quality? Is there an appliance that will do this better? Is there a way to set up a point to point conference? (Quicktime Broadcaster allows this, but has long latency... too long to be usable for our purposes.)
So I'm not getting why I can't do this. Please let me know if you have any ideas.

Ralph,
Thanks. I've increased the RAM size on both sides, have a blazing fast connection, and use prosumer cameras with good glass and lighting. The boxes on both ends are dedicated to this with nothing else running. I've even met with our campus IT lines to make sure there are blocks or plugs on ports. No good.
I guess its in the CPU or something. It's a bit annoying. I'm a really big fan of iChat. We've used it for "live shots" on election night and as broadband field "live shots" over a 3G telephony connection and wireless broadband. Nothing else we've found is better. It just seems to handle video quality less well in the last couple of versions.
If anyone knows the magic formula.... X- machine, X-plug in, X-external box, X-side processor, I'm interested.
Thanks for your suggestions.
David

Bad video quality over WiFi?

iChat seems to be trying to out-think me by lowering iChat video quality when it's on WiFi, but using great video when I'm on ethernet. This seems silly, since I have great WiFi connectivity, but I can't seem to disable the behavior. Does anyone know how to disable iChat's WiFi preferences?
More details:
I'm on an 802.11g WiFi network through an AEBS with "full bars" and the quality looks terrible over Bonjour to someone else on the LAN (wired or wireless). As soon as I disable AirPort and plug in to wired Ethernet, making no other changes other than restarting iChat, the quality looks fantastic.
My WiFi speed is always in the tens of megabits per second, with ping latencies below 1ms to the other clients, so it should be plenty fast.
Ideas?

I have been using iChat exclusively over WiFi (Airport Extreme) from my iMac, and via Ethernet and WiFi from my Powerbook. I have not had any quality issues when connecting in this manner. Connections within my local network from WiFi to WiFi, as well as to outside connections over Broadband have all been of very good quality. Now if I can just get it all working again following the upgrade to Leopard 10.5.1.
FYI: I have even used iChat AV on Tiger using DUN on my Treo650 (Sprint), which worked fine as well.
