Update to 10.10.2 poor video quality

After I updated to Yosemite 10.10.2 video quality became very poor, especially when using the DVD Player App. This is on an 2012 quad core I7 server model connected to a Panasonic TV via HDMI. When I reboot using 10.10.1 which is on another partition of Drive 2, unupdated, the video is perfect. I tried to use calibration in system setting/display/color with very little success. Has anyone else experienced a similar problem?

Very poor video quality after transcoding in Adobe Encore CS5.1

MERRY CHRISTMAS AND A HAPPY NEW YEAR!
I have very poor video quality after transcoding the video file (MPEG) in Adobe Encore CS5.1. Below you see my used settings in my filmproject.
The problem exists after transcoding in Adobe Encore CS5.1. I checked all steps and found out that there is no problem until transcoding. My exported file in MPEG has very good video and audio quality.
Facts:
1. Camcorder: Panasonic AG-AC160AEJ
Operating System : Windows 7, 64 Bit, Ultimate edition
Source files: MTS files
Recording settings (clip settings):
Type: MPEG Movie
Image Size: 1920 x 1080
Frame Rate: 25,00
Source Audio Format: 48000 Hz - compressed - Stereo
Project Audio Format: 48000 Hz - 32 bit floating point - Stereo
Pixel Aspect Ratio: 1,0
2. Sequence settings in Premiere Pro
Sequence was created from Clip directly with settings above.
3. Exporting settings in Adobe Premiere Pro:
Match sequence settings was activated. Now other changes were set.
4. Exported File:
Video
Image Size: 1920 x 1080
Data Transfer Rate: 25920 kBit / s
Frame rate: 25
Audio:
Bit rate: 384 kBit / s
Channels: 2 (stereo)
Frequence: 48 kHz
5. Transcoding settings in Adobe Encore:
I used different transcoding settings such as automatic DVD Transcoding, CBR and VBR.I also set “use maximum render quality”. But all results were always the same: very poor quality.
Why does the encore transcoding cause such bad video quality?
How can I solve this problem?
Please help me soon.
Best regards.

Hi Ann,
1) I did not only „Automatic (based on source)“ options in my tests, but also many other customized options.
The results are very poor. I have done a new test with the following settings. The result is also poor:
Download link: http://www.klavierlehrer-bayern.de/download/test_mpeg2dvd_1.m2v
Export Settings:
Format: MPEG2-DVD
Preset: Custom
Codec: MainConcept MPEG Video, Quality: 5
Frame Rate: 25 fps
Field Order: Upper
Pixel Aspect Ratio: Automatic (based on source)
Render at Maximum Rate: [active]
Bitrate Encoding: VBR, 2 pass
Minimum Bitrate (Mbps): 5
Target Bitrate (Mbps): 9
Maximum Bitrate (Mbps): 9
GOP Settings
M Frames: 4
N Frames: 12
Use Maximum Render Quality: [active]
Multiplexer: None
2) Why shouldn’t I use the “Match Sequence Settings” in exporting? Because of the big output file size?
I used it and the results are very good as I expected:
Download link: http://www.klavierlehrer-bayern.de/download/test_MatchSequenceSettings.mpeg
Export Settings
Match Sequence Settings [selected]
1920 x 1080, 25 fps, Upper, Quality 50
User Maximum Render Quality: [active]
3) I tried also Dynamic Link in PremierePro (to Encore).
The results are also poor.
4) I will test also LagarithLoslessCodec and frameserving +DGMPGDec. But the video is vertical long drawn-ot.
I think I did not use it correctly.

Router Type: Symmetric - poor video quality (blocky)

Hi,
Back in October I posted a question about poor video quality...
http://discussions.apple.com/thread.jspa?threadID=2197561
I wanted to posted a resolution, but apparently the topic "has been archived - replies are not allowed." so I have opened this new one.
With thanks to Ralph for his always informative response and Luis Villazon from MacFormat (Q&A Issue 221) I had a better understanding of the issue, but unfortunately the suggestions failed to resolve the issue.
Then I discovered the DrayTek Vigor 120 ADSL2+ Ethernet Modem.
This is a true modem in that it does nothing else, nothing fancy, no NAT, not DHCP. Just a modem.
Connecting this to the AEBS and setting the 'Connect Using' parameter to PPoE gave control back to the Airport.
iChat now works as expected.
You might say the 'Vigor 120' is the Airport's missing modem !

Richard

How do I fix poor video quality when exporting from Keynote to iMovie

I went through Keynote to create a movie from a PowerPoint (including a soundtrack) but the video quality is very poor in the final product. Is there a way to fix this?

file > export > Quicktime > custom > then select one of the codecs: MPEG-4, standard DV, HDV, AVCHD, Apple Intermediate Codec and use full size in the options.

IMovie - Poor Video Quality when exporting to "Projects"

Hi - I'm using iMovie 11' and once I move my video (HD) from "Events" to "Projects" my video quality becomes very poor and the video is cropped. I have changed my setting to have it "fit frame" but the problem still exists. Thoughts?

@Harm,
"Pear-shaped" (or sometimes "fruit-shaped") is a euphemism meaning that the effort has gone awry; it was a mess.
@John,
Export to DVD is a PPro 2.0 function; in CS3 it is now Export to Encore. Is that what you meant?
First thing is to check the field orders of your source material and of your export settings. Don't invert them, and don't deinterlace interlaced footage.
Perhaps a short list of the settings you have tried (and why you chose those settings) would help us help you.

How to improve poor video quality in iMovie?

I have a movie in iTunes (version 10.6.3). When I play the video, the quality is good on my Mac, on my iPad 3 and on my Apple TV. The Apple TV is hooked to a 42-inch LCD TV.
Next, I open the video file (MP4) using QuickTime Player. I use the Edit and Trim commands to create a 1-minute segment from the video. I save the segment from Quick Time Player. The saved segment is a MOV file. I drag and drop the MOV file back into iTunes. When I play it from iTunes, the quality still is good on all my Apple devices - no noticeable difference from the original.
Now, I import the MOV segment into iMovie 11 (version 9.0.8). At import, I tick the Optimize Video check box and I select the Full - Original Size setting. Once imported, I select Share > Publish To iTunes. I do not make any changes to the video clip in iMovie. I publish to iTunes using all five size settings: Mobile, Medium, Large, HD 720p and HD 1080p. Once in iTunes, I play the video again. Now the quality is poor, lots of pixelation in all five size settings.
iMovie appears to be doing something to the video to degrade its quality. Maybe I have a setting wrong somewhere. Anyone have any suggestions on how to prevent the degradation in video quality? Thx

Hey Brad, the MP4 movie in iTunes is 806 MB. The segment I trimmed in QuickTime Player and saved as an MOV file is 18 MB.
When I export the MOV segment from QuickTime Player to my desktop, the export format options that appear are: Movie; 480p; 720p; and iPad, iPhone 4 & Apple TV. Which do you recommend?
When I do Share > Export Using Quicktime in iMovie, there are a bunch of Export and Use options. Which do you recomend?
Thx

Poor Video quality when importing from SONY DCR-SR100

I am brand new to Mac and iMovie and FCE. One of the reasons I switched to Mac was frustration over poor video output from Windows based video editing programs. When importing video from the SR100 into iMovie and then iDVD, the DVD quality is noticeably poorer than when the camera is connected directly to the Plasma TV. I have been reading these forums and loaded MPEG Streamclip and purchased the Quicktime MPEG2 Download, but I still can't get the video output to look as good as the camera. I obviously have some learning to do, but is there any hope of achieving equal quality output from a DVD as straight from the camera? Is there a good source of information/textbook on this topic? The biggest improvement comes from using the "de-interlace" option in MPEG Streamclip, but the overall quality of the video appears washed out and somewhat blotchy compared to the direct camera footage.

Welcome to the macworld! What imovie does incredibly well is make it easy to create fun and interesting movies. I have used both for several years and only recently with some packages such as adobe premiere elements has the windows world kept up with the mac with respect to ease of use! And even know the packages are still not as easy as imovie. Anyway, with respect to your post and getting the video quality to the best possible output quality using DV material, you are on the right path. The best workflow is to use streamclip and de-interlace prior to editing in imovie. I am not sure if you are doing that yet with your workflow. Yes, its an extra step, but it is well worth it to avoid imovie dropping a field upon export. You can play around with the adjustments to increase contrast, color and et al on the adjustment button. Another option is shooting progressive.
To set expectations, it is second generation footage the minute its imported. However, you should be still getting very good results. FCE gets footage closer to the original footage since it is a true DV editor and uses both fields, but imovie is still preferred by me because of how easy it is to skim, tag and find the material you want then easily do transitions and ken burns for photo's. Fantastic. The way i look at it....watching footage straight from the camera is the worst quality you can get -- It's like listening to your spouse talk and talk and talk and never get to the point until you forget what that point was....editing gets the footage straight to the point....thats quality!

Poor Video Quality after Streaming

Dear all,
We have been provided with a number of .mpg files from a
client and we have streamed then into Flash, using the usual
settings. When streamed however, the resulting video is of a poorer
quality than the original file.
Just wondering if anyone had any ideas - we are probably
doing something wrong, but we've tried a number of various options
when importing.
Any advice greatly appreciated.
The videos produced may be seen at:
http://www.atomicwebsolutions.com/foodesign07test/reel.asp
Many thanks
Dave

Hi B,
We used - at encoding screen:
Profile - Custom
Video Codec - tried On2 and Spark
Quality - High
Frame Rate - Same as Source
Key Frame Placement - Automatic
We used similar settings for .WMV files in the past and the
video quality was fine, but with .MPG files, the resulting quality
is much less than the original.
Best wishes
Dave

Poor video quality after rendering or publishing iMovie video - Problem?

After completing production of an iMovie video and then publishing it, the video quality is absolutely horrible. Is the normal or am I doing something wrong?

I hope the iMovie programming team at Apple is READING THESE POSTS, plus the other threads complaining of the lousy quality that results when interlaced video (480i or 1080i) is imported into iMovie '09 (even with all the recent updates). Various folks and e-book authors have posted workarounds, but these are cumbersome and defeat the entire purpose of iMovie -- which should be a simple and elegant video editing solution. Millions of users have interlaced video which they would like to edit (for you novices, you're affected if your video was shot on mini-DV tapes, or the HDV format -- plua many other non-tape formats also use interlaced video, so check your camera's specs).
Apple, PLEASE ADDRESS THIS GLARING FLAW in iMovie '09. It's absurd that iMovie 6/HD, which worked flawlessly with DV and HDV footage, is no longer supported. IMovie '09 has many great features, but what value are they if the end-product looks bad?

Poor Video Quality on DVD Created by Encore

I am using Premiere Pro CS6 to edit video shot in 1280 x 720. I've linked the sequences from Premiere to Encore and created the DVD in Encore. I did not run the sequences through Media Encoder first but, rather, let Encore handle the transcoding and compression.
The video when viewed in Premier looks great. The video when previewed in Encore looks great. But the quality of the video when burned to a DVD is lousy. I believe that the video on the DVD is only standard definition, but still the text is blurry and the images are fussy and jagged, more than I expected. Is there something else I should be doing in Premiere or Encore to ensure a higher quality DVD?
Thanks,
Dan

Well, I thought I followed the advice I was given pretty closely but I am still having a problem. I volunteered to shoot video for a Special Olympics and was hoping to have already delivered the final video, so any help you might yet be able to offer would be appreciated.
For testing purposes I exported just 3 Sequences from Premiere into Media Encoder (total video length was less than 50 minutes) , transcoded them, and them brought them into an Encore project, but the resulting DVD is still of very poor quality. The video is noticeably blurry and a bit jumpy, and the text is also blurry.
I am viewing the DVD on a 42 inch LED TV. If I view the Media Encoded .m2v files directly from the computer (i.e., not using the DVD) on a large LED monitor they look pretty sharp. This leads me to suspect the somehow I am not using Encore correctly.
I will ultimately split the video in two, using 2 DVDs for different segments, so that the total across the 2 DVD is the original 100 minutes.
Here are my specs:
Original Assets
The original video was shot in 1280 x 720p.
My sequence timelines in Premiere were also 1280 x 720p
All lower thirds text was created in Photoshop at 1280 x 720
Media Encoder
All the video was exported directly from Premiere
Format: MPEG-2 DVD
Codec MainConcept MPEG Video
Quality (as automatically set by the slider) defaulted at 4.0
TV Standard: NTSC
Frame width/height: 720 x 480
Field Order: None (Progressive)
Pixel Aspect Ratio: Widescreen 16:9
Render at Maximum Depth: NOT CHECKED (I forgot)
Bitrate: VBR 2 Pass
Minimum: 4
Target: 6
Maximum: 8
GOP M Frames: 3 (default, I assume since I did not change it)
GOP N Frames: 12 (again, default, I assume)
Encore (all default settings as far as I know)
Only 2.1GB of a 4.7GB DVD was used
I burned directly to a DVD disk
Project Settings:
Authoring Mode: DVD
Television standard: NTSC
Codec: MPEG-2
Dimensions: 720x480
Frame Rate: 29.97
Fields: Lower First

Any additional help you can offer would be greatly appreciated.

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.

Poor video quality, pixelation, flickering on moving subjects in frame

I made a quicktime movie using File>Export>Quicktime Conversion... in FCP using H.264 compression codec with best video quality and 16-bit audio. video was originally captured in miniDV. Self contianed movie was made and looked pretty good in Quicktime, though the edges of moving subjects in frame did have small wavy lines (I assume from interpolation of DV?). Anyway it was acceptable to me (but if there is a fix please advise as I figured this was endemic to miniDV itself.)
Then I created a DVD in iDVD 6.0.3 with several slide shows and two relatively short movies (12-14 minutes in length each). The edges of moving subjects in frame (i.e. persons walking into the frame) now have large square pixelations sort of like this --->( |-|_|-|). At anyrate, the fine wavy lines from the QT movie have become much worse when there is movement, and I'm not talking speed, just any movement like a hand moving in the frame, etc. Otherwise the quality of the video is comparible to the exported movie from FCP.
Does anyone have suggestions for how to eliminate this problem?
thanks!

That's normal interlacing. You usually want to preserve those comb lines if your target is TV display which will hide them and use them to make smoother motion.
http://www.sjoki.uta.fi/~shmhav/SVCDon_aMacintosh.html#interlacing
But if your target is a computer display, then you usually want to deinterlace them off because they look ugly on a PC monitor.
originally captured in miniDV ... H.264 ... Then I created a DVD in iDVD 6.0.3
No! You should not convert the original DV to H.264 if your final target is a video-DVD!
Just keep it as DV. And take care that your FCP export to DV is bottom field first field dominance because otherwise you get terrible zigzag movement artifacts! ...I don't have FCP so I can't give you more advice on that (mini-DV ->iMovie ->iDVD handle all this automatically).

Poor video quality when exporting from Adobe Premiere

Hey, I was just wondering if there was anyone here that could help me with this problem I am having with Adobe Premiere Pro.
I have used it to edit a movie together with MOV video files from my iPhone 3GS which are of decent quality but everytime I try to export it, the video quality is degraded significantly from the original. I have tried several different export options but none seem to do the trick.
Also, exporting with DivX just gives me an audio file with no video so I have been unable to try that.
Anyone have any ideas?
Thanks.

Very Poor Video Quality

I was trying to iChat with my daughter this afternoon and the video quality was horrible. She was pixelating large and small, trailing, etc. I think it may have something to do with the refresh rate. She has a new MacBook, which I assume is running 10.5.6. Any ideas?

Hi Defcom,
thanks to you man, finally my iChat Video is working. After fiddling around for several weeks and not finding the answer, I saw your recommendations for the Quicktime-streaming and the bandwide maximum, put it to work and now iChat is working.
Thanks to you man.
This leeves the question why such important information is nowhere to be found in the documentation of iChat. This is a serious omission in my opinion. Look at how many people have problems with iChat Video! And then such a simple solution, just somebody has to tell you.
Thanks alot again defcom.
