Poor quality conversion/downsizing with Aperture Export

I have noticed a difference in quality of exported JPG files, depending on if I downsize them manually, ahead of time, using an external editor (PSE) or if I let Aperture downsize them during export. The images downsized in PSE are noticeably sharper than the ones downsized by Aperture. Originals are high res JPG files from my D90 that I have converted to TIFF and touched up using PSE as an external editor. I would like to keep the full size, adjusted TIFF file as a master and just export to whatever size JPG is needed at the time. With the low quality Aperture exports (compared to downsizing first in PSE), I am having to individually downsize each TIFF in PSE prior to exporting as a JPG in “original size” mode (vs. letting Aperture handle the downsizing). Has anyone else noticed this degradation when exporting/downsizing in Aperture2? Is there any work around? Any comments would be appreciated! Thanks! (All export was done in JPG quality 10, with no pre-sharpening performed.)

Firstly, using window>show movie info, find out what the current bit rate is of the original movie.
When you come to export, keep the bit rate as close as possible to the original bit rate, keep the resolution the same as well as the frame rate. You should hopefully get much better quality.

Poor quality Photo printing with the HP Officejet 6600

Is anyone having a problem with the HP Officejet 6600 having very poor quality photo prints?

Hi HereInJersey,
Welcome to the HP Support forums. I understand that printed photos from your Officejet 6600 don't have the quality that you expect.
I have included the "Fixing Ink Streaks, Faded Prints, and Other Common Print Quality Problems" troubleshooting document. It has detailed steps to take to improve the quality of your print jobs.

Poor Quality of Photo JPEG Quicktime Export PPro CS4

Adobe Premiere Pro CS4
2 Xeon Dual Core 3.2 Ghz
2 GB RAM
XP SP3
Nvidia 8600 GT
The program that I use for presentation (ProPresenter) prefers Quicktime files rendered in the Photo JPEG format. I render it from a HDV 1080i 60 time line to a 1280x720 file.
In CS3 this worked great. In CS4 when I render it out, the file looks terrible. I even bumped it to 100% quality (normally I do about 85% in CS3)
The video has bad posterization and looks like it has been rendered at a low bit rate, which I think may be what is happening. CS3 didn't let me set the bit rate, and neither does CS4, but 2 minute files took about 700 MB to 1 GB after being exported in CS3. The resulting files in CS4 are 150 MBs.
The bit rate option when Photo JPEG and many other Quicktime codecs is selected, is greyed out and cannot be set.
So what can I do? I NEED to be able to export to Photo JPEG at high quality. Why would Premiere not allow me to set a bit rate, but more over, use such a low one? At least in CS3 it chose a high bitrate for you.
Am I missing something? Are others having this problem with Quicktime exports?
Here is the output from CS3. Some banding in the bacground gradients, but that's to be expected with JPEG.
Here is the output from CS4. Banding is much worse, jaggedy posterization, obvious artifacts. All of this becomes even more apparent with motion.

I would like to follow up a little bit. After talking to my friend, the bitrate problem was addressed in the 4.1 patches and exporting to Photo JPEG at least was fixed, at least that's what he told me and from his description of the problem, I'm quite sure he knew exactly what I was talking about.
But still, after he listed his annoyances such as the much longer render times, and an interface and timeline playback that just never seems to be quite fast enough to keep up, I long for the simple interface of Premiere 6.5 with updated HD capabilities. Every step since then has made the interface more unnessarily resource intensive.
I don't think I'll be upgrading to CS4, sorry Adobe. Please stop making Premiere for super machines. I have a very good computer, and it's having trouble running Premiere CS4. It doesn't NEED to be this resource intensive. It doesn't have to bog down when it's run on anything but the best of the best computers.
In a simple A-B-C comparison, the speed of playing an HD clip with a couple effects goes down and down and down as you go from Pro 1.5 -> CS3 -> CS4. Why? What other areas are so improved that we need to have such a slowdown of the core?
Sorry, I'll stop venting now. I was just so hoping that I could recomend we upgrade to CS4 and solve some of our CS3 problems.

Poor Quality in Wide-Screen When Exporting HD to Quicktime

Hello all...
I'm working on a fairly large project in iMovie HD with wide-screen footage from my Sony HDR-HC3 and have hit a wall.
I can't seem to get a good result when I export clips into Quicktime in a wide-screen format. They are a bit choppy & you can see bits of some horizontal lines. The same video exported in full-screen VGA looks great. Any tips...? I basically just want to make good quality QT movies watchable on my computer that maintain the original aspect ratio (and LOOK like they do in iMovie!)
The entire project is around 100GB and I currently have almost 40GB of free space. Any help appreciated!

What do you need to end up with? Just a file to play back or burn to a DVD or make a web stream or?

Poor quality motion tween with png image, tried "Trace Bitmap", but then it looks like a newspaper

Greetings all,
I've been a software developer for many years, but am not very savy in the design elements. So, much of what I'm going to say will probably sound "newbie", so please forgive me in advance.
So, I'm trying to get a transparent image to fly in from the side. So, I *thought* I was doing the correct thing by moving the "symbol" off of the visible portion of the stage, and creating a motion tween to move it onto the stage. The motion works, but the quality of the image in general (and the text in specific) looks pixelated.
Thus, I did a little bit of snooping, and everyone said that you should start with a bitmap. So I saved the image from Photoshop into .bmp format, and was able to set the properties to "allow smoothing" and with lossless compression. So far, so good. Now, as I expected, the transparency is no longer there...
So here's the question: how can I make this image retain its quality, still have transparency, and a motion tween?
It seems like this is some set of characteristics that don't play well together, even though I see this type of thing online ALL the time.
I tried "Trace Bitmap" to convert to a raster image, and tried to follow some suggestions online, but when I do "Trace Bitmap", it ends up looking like it has a bunch of grayish dots on the image... definitely NOT what I was expecting.
Thanks for your help!
JPB

Go back to using the png, and set the smoothing allowance. That should take care of the quality. In Flash, a "bitmap" will often refer to any type of image element... .bmp's are probably dinosaurs (as in extinct) where Flash usage is concerned.

Poor quality on multiple level video export. What am I doing wrong?

I'm having a problem with exporting a video I've been working on with FCPX.
The output file looks like it's being screened on a venetian blind with very small slats - ie the image appears to be made up a lots of narrow horizontal panels. I also get a kind of striated effect around all the edges (which I managed to eliminate in my latest attempt - see below)
The video looks fine in FCPX - it's only when I export Media that I'm seeing this problem.
The sections that I'm having this issue with consist of a background texture generator in the Timeline, and two layers of video clips above that. The video clips are resized and positioned top left and bottom right of the screen (overlapping in the centre), so that you can see two separate video clips playing over a background. At different points one or other of the clips expands to fill the whole screen.
The clips are variously original clips, compound clips, and a compound clip with slo-mo video in it.
(The reason for doing this is that it's 2 cameras following 2 separate, but simultaneous, processions. Sometimes I cut between them, but I also want to see both processions at the same time during the piece).
I've tried exporting using standard settings, Apple ProRes 244, and h.264, and I've gotten the best result so far by exporting to Compressor and using MPEG2 for DVD settings, with De-interleave turned on and giving it two passes. That got rid of the striations, but i still get the panel effect.
If I export a different section of the video, that only uses 2 layers of video (without the background generator, and with one layer of video in the Timeline), then the resulting export looks ok even with a standard settings Export Media, so I'm assuming that it's something to do with the attempt to give the images a background. This also may not be the best way to go about this, so I'm open to suggestions about _how I should do it!
If more info about how I've set up opacity etc is needed, let me know.
thanks for any help

Editing on a Mac Mini with 8mb ram (FCPX runs faster than on my MBPro!); FCPX1.1

I'll just add that I reimported my footage, using the Optimise media settings, and exported a short clip using Export media (ProRes 244) & Compressor (ProRess244 + DeInterleave filter). Neither showed the "venetian blinds" effect, but the first export had loads of fringing, and the second had a lot less, but there was still some visible.
Anyone? Is this a bug or some kind of operator error?
thanks

Poor quality save for web exports

It doesn't matter whether i'm exporting from Ai or Ps or whether it's CS6 or CC. I have changed the raster settings in Ai and i've also tried all optimization options with all different export file types (jpg, png, gif) at all different quality settings. It doesn't matter if I start with an ai, eps, pdf, png... the export result is always poor quality.
I have tried exporting at 300ppi and that does fix the quality issue and bloats the file size, but this way (the export route) is so time consuming since you have to resize your artwork each time as well as the artboard so that it doesn't cut off pixels. Save for web never used to have these quality issues and it also never used to cut off pixels around the edges. These workarounds prove very time consuming and produce file sizes that are not ideal.
When i first noticed this issue I was using Mavericks with CS6 and since am using Yosemite and Creative Cloud.
Steps to reproduce:
1. Create any bitmap or vector graphic in Ai or Ps, It doesn't matter whether you convert text to outlines or not
2. Save for web
3. View image in any application or browser to see poor quality and pixel trimming. Others running the same version and system are not having this issue, but I have checked many forums and found many others that do have this same issue but can't seem to find a solution.
Results:stair stepping, degradation, pixel trimming, general poor image quality
Expected results: Previously the save for web feature allowed for a decent quality image

Not an Illustrator expert at all, but did you align your art work with the pixel grid? If you didn't, there can be results as you describe them. As I said, I am not an expert, but online searching for the subject may help.

Very poor quality ichat video

I am new to ichat and I have very poor quality video links with my family. One in CA and the other in TN both are on macs. They are both very fragmented and broken up. Also there is a huge delay in the audio. Please help....I can't see my new nephew. Thanks

i am also having issues with my ichat video quality, and there is a delay on audio sometimes. i chat with my friend in philly; i am in brookyn, ny. sometimes the audio is in sync, and then sometimes we have a delay. but the video quality is so blurry on my end...i can barely see her. but her video of me is fine. my preview screen looks great, the connection doctor says everything is good.
i'm not very good with macs tho and computer jargon. i need someone to help me, but who can walk me thru this stuff like im in first grade.

Poor quality Export for HD with moving objects

When I export from iMovie6 any moving image is very poor quality. I am using a Sony HDR-HC1 and trying to export at the highest possible settings.
When the image is still the quality is very good, but if anything moves the image goes "wobbly" and "jigsaw" like. Panning shots are hopeless and anyone walking in the shot goes wobbly.
The original capture image seems fine, so I assume it is an exporting problem. Exporting at lower setting, ie for an iPod, the image is great.
I have tried all different setting, some are better than others.
Can anyone help?

Your description of the problem - a 'comb' effect - sounds as if the "fields" which make up the resultant picture have been put together in reverse.
(..You don't normally see 'interlaced' video in iMovie's playback window - you normally see just a single field of the two, to make the picture clearer and simpler to display..)
[..A video picture's generally made up of two "fields" which each comprise half the number of lines down the screen: one field comprises the odd-numbered lines, and the other the even-numbered ones. Your exported video should be encoded with the lower (2nd) field first ..as described in this Apple document ..and the problem's mentioned here as well..]
However ..you said in your first post that "..I am using a Sony HDR-HC1 and trying to export at the highest possible settings.."
This is an HDV camcorder, and you didn't say if the original footage which you shot was HDV or normal DV. (HDV is recorded differently from normal DV, as it's recorded in a more compressed format, and it has to be automatically 'unscrambled' by Apple's Intermediate Codec while you're importing it into iMovie HD.)
It seems as if somewhere along the chain of importing>editing>exporting, the fields are being reversed, so that you get this jumpiness on replay when QuickTime tries to deliver a "highest quality" interleaved replay of both fields:
Ah ..sudden thought: you mentioned that you exported thro' iDVD: "..I have used iDVD by dropping it into a DVD theme and it seems to work ok, although the playback is a little jumpy, not quite as good I would have expected.."
You may have left the iDVD settings at their default 'NTSC' instead of switching them to PAL.
Check your iDVD Preferences ..that may be the problem.

Camtasia Poor Quality in Premiere CS4 Export

I am a PC user. One of my clients uses Mac and Camtasia to screen capture his software program, which I need to integrate into a video I am making for his company. The MP4 Camptasia file he sends me looks good. I bring the file into Premiere to edit it, but when I export it, the clip done with Camtasia has very poor quality, while the footage I shot with my video camera looks great.
Specs:
Camera: HMC40, PH mode 1080/60i (MPEG-4 AVC/H.264 compression).
PC: i7 quad-core 64-bit running Windows 7 Professional 64-bit, 8 GB RAM.
Editor: Premiere CS4 in the Adobe CS4 Master Collection .
New Sequence setup in Premiere: AVCHD > 1080i > AVCHD 1080i30 (60i) Anamorphic.
Premiere’s export settings:
Format: MPEG2
Preset: HDTV 1080p 29.97 High Quality
Multiplexer tab > Bitrate and Buffering Details: Variable
Video Tab > Basic Video Settings > Quality: 5
Field Order > None (progressive)
Profile > Main
Bitrate Settings: Bitrate Encoding: VBR 2Pass
Minimum Bitrate: 4 (default)
Target Bitrate: 15 (default)
Maximum Bitrate: 18.5 (default)
GOP Settings > M Frames: 3 (default)
N Frames: 15 (default)
Output summary: NTSC, 1920X1080, 29.97 drop frame (fps), Progressive, Quality 5.0
Note in general: I found that if I set the Bitrate Encoding at VBR 1Pass, I got glitches sporadically.Using VBR 2Pass has solved this.
My question about the Camtasia clip:
1) How can I get the Camtasia footage to be as sharp in the export as in the original?
Other questions in general:
2) Are my New Sequence setting in Premiere correct? AVCHD > 1080i > AVCHD 1080i30 (60i) Anamorphic
3) Is my choice to export as MPEG2, HDTV 1080p 29.97 High Quality preset, the best for the footage I shoot?
4) Is my choice to set the Multiplexer tab > Bitrate and Buffering Details at ‘Variable’ the best?
5) Do my Bitrate and GOP settings need adjustment?
6) Should my Export field order be Upper instead of Progressive?

function(){return A.apply(null,[this].concat($A(arguments)))}
The frame rate is 1038 X 882
That is a very odd frame size, and one that probably won't work well no matter what workflow you use. You asked:
function(){return A.apply(null,[this].concat($A(arguments)))}
how could he better capture and export to match my workflow?
Have him capture and export to match your desired export frame size for the finished project.
function(){return A.apply(null,[this].concat($A(arguments)))}
How would you suggest I change my workflow to handle the interlaced and progressive issue?
I can't answer that until I know exactly how you intend to deliver your finished video. Any answers to your other questions will also likely depend on your intended delivery format and media.

Extreme poor quality in full screen preview and exported movie

I have spend evenings and evenings to create the content of a project.
After dealing with error -108 and extreme poor quality in full screen preview and in exported movies (extreme stuttering) I decided to install my iMac new again.
The error -108 disappeared, but the extreme stuttering still remained in full screen preview and in exported movies.
If I make the preview screen in the iMovie browser as big as possible there is nothing to see of any stuttering.
Now I am getting pretty annoyed and have no clue what to do anymore (how to solve this problem) .....
Anyone any suggestion ?
The orginal video was recorded with a Panasonic HD camcorder.
I do have a mid 2011 iMac with 16GB ram and 256GB SSD and 1TB HD with a complete clean installation
of OS X Lion and iLife. This configuration should be enough to create a proper movie :-(

why is it this option disabled? do the generate monitor sized previews increase a lot the cache a lot!
Potentially, yes. The standard Preview is 1024 pixels, longest size. Some people (like Omke) have displays 2560 pixels longest side, potentially increasing file size by over 500%.

Poor quality image with doing videos with photos/images HELP!

Hello,
I bought Adobe Premiere Element to make videos with pictures. When I do the video, the quality of my photos is good. When I save the video on my computer or I download it on youtube (example) the quality of my photos is extremely poor. Why? Does anyone can help me? Thank you!

What Project Preset did you choose at New Project? In the case of Video, composed of Still Images ONLY, you would set that to your desired delivery specs. Not so, if you are also using Video. I tried several types of parameters. Some parameters give poor quality when I upload it to Youtube (for example) and others in the design of video and upload to YouTube. So which settings should I use for photos only ?
This sounds like you are talking about the Export/Share settings for output to YouTube.
What I was asking is what did you start off with, when you were at New Project?
If you are doing an SD Project, you will have either 720 x 480 (NTSC), or 720 x 576 (PAL) pixels in the Project's Frame Size. If that is what you want, then I would Scale your camera original Stills to 640 x 480 (for NTSC), as you have Square Pixels, and the Project will have either 0.9 for NTSC Standard, or 1.21 for NTSC Widescreen).
PrE can Scale the Still Images, but the Scaling algorithms in Photoshop are much better, and offer more control.
Now, if you wish to do an HD Project, just choose that as your Preset, and then use the Images in about their original size. Note, there will be some black borders, as the screen-caps most likely have a different Aspect Ratio, than a Video Project, which for HD will be 16:9. Especially with screen-caps, that are pretty low resolution to begin with, I would NOT do any Scaling, and would live with the letterboxing, or pillar boxing, rather than Scale and effectively Crop.
Also, when Scaling in Photoshop, I do not Save_As JPEG, as it introduces compression, but only as either PSD (Photoshop's native format), or PNG.
Good luck,
Hunt

Export via Quick Time ends up being pixelated and poor quality

I shoot my student film on an Arri S camera with 16mm color stock. I got my film back to me from the school on a DV tape and imported it into FCP HD on my camcorder. When I went to export it onto a DVD for my actors, the film looks horrible! The blacks are really pixelated and the colors aren't as crisp as they were on film. I was told that it should look the same because we made the movie on better equipment and FCP won't lessen that, but at the same time FCP can't make poor quality work any better. Can someone tell me how to export my film without losing the 16mm quality. I don't want it to look digital, I spent a lot to get the real film stock. Thanks!

1- The film is 6 minutes long
2- I don't know where to find out about the bit rates
3- The audio is simple, just 48 khz stereo.
When using DV format, what's the difference in DV, DVPRO, etc.?
The movie was filmed 24 fps, but then put onto a dv tape for me, so I assume they transferred it at 29.97 fps. Should I now use NTSC or stick to PAL? Basically, anymore compression makes the film look really bad and unusable for festivals, which ultimately was the whole purpose of my blood, sweat, and tears behind this film.
Thanks for all your help and any more questions you need answered to solve this problem I'd be more than happy to answer.

Poor Quality Export to AVI

Hi im a newcomer to Premier Pro and need some help in adjusting my settings for exporting my video.
The video in question is made up of 5 seperate videos (created from still jpegs with ImageVideoMachine at 1024x768 with 24fps and 1080HD Profile). When I view these videos seperately they are good quality and do not have any problems. However after i imported them to Premier Pro and added an audio track in the background and a small bit of text the quality after export is really bad in places.
I have tried lots of different settings in the export but just cant seem to get it right. The main problems that seem to occur is when the camera moves quickly from one scene to another and it seems to get very blurry and pixelated and sort of like half the scene is catching up (hope this makes sense!).
The entire video is only 4 and a half minutes long so I am not too worried about the size of the file. Any help would be greatly appreciated as im at a loss what to try next and the poor quality of the video takes away so much from my hard work in creating the presentation.
Hoping you can help
Alan

Poor Quality Export. PLEASE HELP!

In FCP X, I am trying to export my project in full quality. I went to quicktime export like I did in FCP7 to create a reference file for burning to DVD but the file was very pixilated and poor quality. what should I do to create a full quality export in FCP X?

So you captured via Firewire ... then it seems likely the footage is DV.
You imported the footage into FCP X, edited with it, and then exported using Share > Export Movie w/ Current Settings, yes? If not, how? What specific steps and settings did you use?
And then you burnt a DVD with the exported movie file and it looks pixelated on your TV? Did you do a direct DVD burn test using the original capture files, just to test that they are not teh problem?
Cheers
Andy
