[SOLVED] Images being rendered in abnormally low quality

Hi guys,
I'm not entirely sure what the issue is since I don't usually play around with image {libraries,software,etc} on Arch, but I have noticed recently that images on Arch, regardless of WM/DE, have been rendered (drawn?) in very low quality.

(Changed from image to URL, resized image didn't show what I wanted it to.)
For example, in this screenshot, you can see artifacts around the fonts and icons that normally shouldn't be seen. I took the same image with both scrot and xfce4-screenshooter, and both images look exactly the same. I'm not sure if there's something really obvious I'm missing or what, but I'd appreciate some sort of guidance.
Regards,

I tried taking the images in PNG format and they still came up low quality.
EDIT: Nevermind, I didn't realize scrot had a quality switch. Disregard this entire thread, it's 2 AM and I'm tired!

Rendered video very low quality

My camera shoots in MTS format. I converted the file to mp4 and edited it. I then imported that footage into After Effects and when I tried to render the video it was very low quality. I made sure the composition settings and render settings matched that of my video. I tried saving it as H.264, mov, avi, m4v, and mpeg2 non of which were good enough quality to use. The avi format came close in quality for the video but everything seemed to move in slow motion. The audio played perfectly though. I also tried rendering video directly from the MTS file and it still didn't work.
Is there a specific way I should convert or encode the file? I tried some different settings within Adobe Media Encoder but when I brought the file into AE and tried to render I got the same issues of it being low quality.
This is for a client so it's very important that I get the needed effects added to this video. Thanks in advance for any help!

I understand how After Effects rendering works and different file types. I just wanted to try rendering in different formats just make sure I hadn't missed something. I figured something out that came close to the quality I need so I guess it will have to work.
My original MTS file is 1920 x 1080 and 29 fps.
I rendered it with these settings originally
NTSC, 1920 x 1080
29.9 fps
Bitrate CBR 30 Mbps
The file came out choppy and noticeably lower quality.
The last time I rendered it with these settings:
NTSC, 1280 x 720,
59.94 fps
Bitrate CBR 20 MBps
The quality was much much better. It still had a little distortion with a lot of movement but it was much more bearable so I guess that's what I'm going with. If anyone knows of any better settings it would be greatly appreciated! Thanks.

Help please -My HQ photos are being rendered in very poor quality in iMovie

Hi there
I have a problem I cannot solve in iMovie (HD 6.0.3).
I am making a movie/slideshow of photos using very high quality photos imported from Aperture. I'm finding them incredibly BAD quality when it comes to the rendering of finished product, the most obvious problem being the pixellation (seen as wavy lines) when the Ken Burns effect is used. It looks the worst on a plasma television, which it is being made to watch on.
I have burned it at the highest quality I can find, but there is still no improvement. Can anyone help please? I'm doing this as a gift for my parents, but don't want to send them something of inferior quality.
Thanks!
Carly

if you've burned it to DVD, then its probably a standard definition iMovie project which means that is 480 lines interlaced. it makes no difference how high quality the originals are, they'll still be re-sized down to 480 lines and since its interlaced, that means that you're only ever showing every-other line. and because standard definition alternates between the odd and even numbered lines, you'll probably see lots of shimmering in the highlights. it will look worse when you try to stretch it across a high-definition TV because there's interpolation going on to up-convert the whole thing back to the 720 or 1080 lines of high definition.
in short, you'll never really get super-high quality from a standard definition TV and you'll only get good results on a high-def TV if you keep everything high def (720p or 1080p) throughout the entire workflow. and until Apple updates its software to handle Blue-Ray or HD-DVD authoring, it'll be very expensive to master those kinds of discs!
best of luck,

Lightroom 4.1 low quality image in develop module

Hi all, i have a macbook pro with retina display, in my lightroom 4.1 the images in the library look normal but when i go to develop module the image is blurred and very low quality. In settings the rendering are high quality 2048 1:1
Any way to fix this? Also in my external monitor i notice this thing with minor loss.

This probably won't help you but the preview settings don't affect the Develop module. In Develop the image is rendered from the raw data.
Are you seeing this with raw files? JPEGs? Is it a huge camera file?

When rendered, still images appear in low quality

Hello everyone.
I'm facing an interesting dilemna with Adobe Premiere Elements 8. It usually works fine for me, and with time I have learned to fix most of the details that usually bother unexperienced users such as me.
What happens is that I'm importing still images (JPEG) to my video, and when rendered they're final quality appears to be so low. I mean, you can see the pixels very large, square-like, you know... as if I had a small image and had it stretched out a lot, but that was not the case at all.
I never had this problem before, and I can't recall anything different on my part in this new video.
Any ideas as to how to fix this?
Thanks everyone.

Hi everybody,
It is a bit late to join this discussion but for vacation reasons I didn't follow the PE-Forum for a while.
I think I have a comparable problem like fmrees: Since a couple of days the resolution of the Preview in PE8 is rather poor. Unfortunately I can't say exactly when it startet. Maybe it begun after I rendered the project.
After having read this issue I deleted the rendered files, looked at the preview: still the same. Re-rendering didn't improve the result.
The difference between the problem of fmrees and mine is: I do not use at all still images. The only video sources are AVI-Files from MiniDV.
I looked at other PE-projects I didn't touch for several week: I have the same problem! So probably it is something in the PE- or project-settings, but I have no idea what it could be (I am rather a newbee in PE).

Upgraded to CS5.5. Images in Indesign are displayed in lower quality after being saved in PS

Hello,
i upgraded to the Creative Suite 5.5 today and detected a strange behaviour. I work on a document which has been generated on another system with an older version of the Creative Suite. Everything is
fine until i open and save one of the images which are used in an Indesign-Layout in Photoshop. After doing this the saved image is displayed with lower quality than before while all other pictures
remain at the same preview quality level. Of course i can change to »Überdruckenvorschau – maybe overprint preview« (Sorry - i do not know how this is named in the english version) or change to the high quality view but
this is a little bit too much for working.
Do you have any ideas?
thank you so much,
tm

I suspect the old High Quality preview was retained (like the text layout will be retained on a converted file until you touch the story in some way, at which point it will be recomposed using the new text engine) and when you replaced the image a new prview as drawn using the current view settings.
Enable High Quality Display if that's the view you want.

Low quality images in web gallery from Output Module

So when I create a web gallery slideshow using the output module I get SUPER-low quality images, like big jagged, pixellated lines in place of any diagonal line in the pictures. However, only photos in the portrait orientation are affected by this problem. Landscape-oriented photos look perfectly normal, just smaller.
My first thought was that maybe the images were low quality in the web gallery preview but wouldn't be in the actual saved file, but alas I saved the index.html file and when I preview it in my web browser I get the same result with the portrait-oriented photos.
Any idea how to fix this? Other than only using landscape photos in my gallery of course!
Thanks!

The same problem here. I've noticed it just yesterday, but my Safari rendering is affected the same way.
I don't think it has anything to do with the recent updates. I reinstalled my MacOS X Leopard day ago and all the images (jpg, gif) have been somehow in lower quality ever since that moment. Even before I installed all new updates today.
The strangest think is, that it wasn't like this before the reinstallation. I used the same media, and I have, indeed, the same machine.
I'm hopeless. Have you already found some solution? Or anybody? Would be great...

Incorrect image size and low quality file (Photoshop CC trial ver. on Macbook Pro Retina)

At first, I set 500x500 size
but in workplace, it show smaller than 500x500 (maybe 250x250?)
I check on "image > image size" it still show me 500x500 pixels
Save for web
After that, i got a 500x500 file but It resize from smaller to 500x500 , so... i got a low quality file.
what's wrong?
(sorry for bad english skill but i really want your help)
Ps. it also incorrect when i set resolution as 300dpi

Pixel is not a measurement unit of length per se.
If a screen has more pixels per unit of length an image (when displayed as one image pixel per one screen pixel) would appear smaller than on a screen with lower resolution.
To make sure could you please post an image that is 500px x 500px (according to Image > Image Size) but seems to be too small to you?

Moto X (2014) receiving low quality images over MMS

I've had 2 different Moto Xs 2014 and both receive images in really low quality (pixelated, lower resolution). I've tried MMS through the verizon messaging app, Hangouts, and the MMS app. My Moto X 2013 did not have this issue. Does anyone know if this a network issue or a Motorola firmware issue?

Im having the same issue on on my 2014 Moto X running Android 5.0, no matter what messaging app I use. Incoming MMS are less than 30kb but I can send at the normal 700kb. Extremely unusable resolution. Factory reset my phone and tried Verizon messaging plus which worked for one incoming MMS but subsequent messages were back to <30kb. Went into a Verizon store and checked my APN settings against different phones which were identical. Verizon employees had no explanation either. Not sure if its a Verizon issue or Motorola issue.

Final rendering of video is low quality and too bright

Here is the link to my original video clip, the video clip in the project, and the final rendered copy all on my monitor at the same time:
http://i157.photobucket.com/albums/t63/shadon1nja/FixingRenderQuality_zps124306a5.png
Here is the text of each video when fullscreened screened:
http://i157.photobucket.com/albums/t63/shadon1nja/RenderText_zpsd1240701.png
The picture got downsised which makes it harder to see the issue,but here is most of the it:
The final copy is lower quality and way too bright. Noticibly too bright. The clean darks turn into rough gray, and the quality is noticibly lower as well. I have checked the "use maximum render quality" and tried exportiing in AVI and MP4, and nothing is fixing it. Any ideas?

First of all, what type of file do you need? If you're looking for lossless quality then I would suggest exporting a quicktime file with the Animation codec or some other lossless codec. However, these type of files are huge and they might not play back on your desktop. But, if you're just going to put this video on the internet when you're finished with it then I would suggest starting with one of the Youtube or Vimeo H.264 presets and modifying it to match your clip. It still won't look as good as your original, but you can't expect miracles when working in SD and exporting to H.264, which is a very lossy codec to begin with. If you want to try exporting to a lossless Quicktime or AVI, then change the settings so they look something like this:

Aperture 3: low quality preview images

I don’t know if it's just a problem with my (new) Aperture Trial library or if it's a Aperture 3 bug:
The preview images Aperture 3 (trial) creates from raw files (in my case NEFs) are different from the JPEGs exported using the same JPEG settings.
I get the impression that the preview images don’t use all the adjustments applied to the raw files. They don’t have the moire reduction applied. The preview images of high ISO images have color noise, the exported images don’t have that color noise (the moire and noise settings of raw fine tuning are applied to the exported files but not to the image previews).
As the preview images are used for the Finder media browser, iLife, iPhone/iPod touch picture sync and other things the lower quality is not acceptable for me.
The preview images of Aperture 2 are identical to the exported JPEGs from Aperture 2 (using the same settings).
I use Aperture 3 Trial with a new trial library and a few hundred raw images just to test Aperture 3.
I already erased all preview images and rebuild the previews. I deselected using the embedded JPEGs from the raw files and I let Aperture rebuild the miniatures.

It seems that Ap2 syncs the previews to the iPhone... you have to clear the previous cached previews before it will load higher quality previews... anyhow, here is what I did... and photos look better on my iphone (not feeling motivated enough to verify if it is the same quality as iphoto sync)...
1.) change Ap2 prefs for "limit preview size" to "don't limit"...
2.) select all the photos in the album(s) you are want to sync, right click (ctrl click), and select delete previews...
3.) sync your iphone again...
if that doesn't work directly, you might need to uncheck sync photos to delete all photos on the iphone, but the ultimate goal is to ensure refresh with the higher quality previews...
Hope that makes sense or gets folks in the right direction... Apple really needs to put a check box in future version of itunes to sync full quality or something...

Low Quality Image for Purchased TV Show

Greetings - I have recently purchased a TV Show (MLBaseball game) from the iTunes Store and was surprised by the low quality of the image. Basically the overall image is far from as crisp as it was in the original broadcast on commercial TV. I have a relatively high end graphics workstation, so the Mac is not the issue. Any thoughts on how to improve the quality of this substandard download? Thank you.

Do you mean "MLB baseball" (it took me a while to figure out what to search for)?
Poor quality is a relative term and it would be good to get information about the file resolution, etc. Actually, pretty much anything on my computer looks better than on our 20 inch CRT television, but I later also figured you don't have one of those. Still, it's a matter of relative standards. On the FAQ site they say something about packing a baseball game into half a GB of file space. Even with modern codecs that may not produce crystal clear images if you're used to HD TV.

Low-quality iPhone images from Aperture 2.0

Hi. I'm trying Aperture 2.0, and I configured iTunes to sync some photos from Aperture with my iPhone.
The problem is, the photos on my iPhone from Aperture are noticeably lower in quality than those synced from iPhoto. The images are blurry and look like low-quality JPG's.
In Aperture's preferences, I set the preview quality slider to maximum and set the limit preview size menu to "don't limit". Still, the images on my iPhone are of poor quality.
Is there anything I can do to make the images Aperture exports to my iPhone look as good as those synced from iPhoto?
Thanks!

Why is "zoomed out" image low quality?

It seems whenever the display zoom is less than 100%, CS3 uses some kind of "Pixel Resize" for display which makes for low quality output to look at.
Is there any way to tell CS3 to a simple bilinear filter when displaying less than 100%?
This would make for much less artifacts/jaggedness and I'm sure the speed impact would not even be noticeable.
Thank you,
LTG

>Should a pixel editor, at a non-100% zoom level, smooth things over to make them look good, so you might pass on viewing at 100%, falsely thinking the image is fine?
again, what if you want an overall view of your image, not just a 2"x4" secion of it? shouldn't you have that option via a toggle?
>Or should it use something similar to pixels from the image that might clue you in to a need to zoom to 100% to see if editing is needed? I vote for the latter, which Photoshop delivers.
it uses NOTHING similar to the image! it's nearest neighbor guesses are way off. I'd rather see the title bar go red as an indicator and see a closer representation of what the image is supposed to look like.
so that's 3 excuses now. 1) it's so you know what to go back and edit. no. becuase ANYTHING VIEWED AT A NON-100% ZOOM LEVEL IS INACURATE! 2) it's to protect you from saving when the image isn't really ready to be saved? no. becuase ANYTHING VIEWED AT A NON-100% ZOOM LEVEL IS INACURATE! 3) it should show you crap because then you know you need to go back and look at 100%. NO! because maybe you produced crap to begin with! :)
I hear what you're saying mike, and it's the closest to a reasonable explination in this thread, but wouldn't it be nice to allow the USER to choose what they see?
