Image quality in canvas

Hi,
Once the project is rendered is the image quality in the canvas the same as the final product? How about when it's digital cinema desktop?
I shoot on mini-dv.
Cheers,
Tom

Yes, but you can only see it properly on a video monitor or when viewed at 100%.
Not usually, the computer monitor resolution is usually a lot greater than the DV resolution of 720 pixels across.

Still image quality loss b/t viewer and canvas?

When I import a still (I've tried jpg, tiff, etc), the image quality is perfect in the viewer, but as soon as I lay it down on the timeline it is blurred and foggy. What am I doing wrong? Please, any advice would be helpful, as this is for a job and I can't hand this in as is...

I'm sorry, I just realized someone else posted a similar quesiton. I jumped the gun.

Loss of image quality after rotate canvas

PS7 on Win XP
Windows Explorer and some software bundled with digital cameras [Canon and Panasonic] warn when rotating a picture that there may be loss of image quality. Presumably it must re-compress the jpg image file?
In order to avoid that problem, I have been rotating image files in PS7, since no such warning comes up there.
Is there loss of image quality by rotating or cropping in PS7? I usually save jpg files at quality level 10.
TIA
Bruce

Bad Quality in Canvas and Exported Movie

Hi,
I'm a new user of FCE. I want to use it for presentation of my software on the internet. I have a screencapture video in quicktime format. The resolution is 1008x744px. This quality is perfect.
If i use this Video in a sequenz, the quality in Canvas or in the saved QuickTime Video is terrible.
What can I do to improve the quality?
Thanks for the help...

If you are displaying the whole screen it will look bad and there is no way of avoiding it.
It is caused because your screen is probably 1200 pixels (or more) wide but a DV image is only around 700 pixels wide so you are losing a tremendous amount of detail.
To make matters worse, much of the fine detail on the screen will probably shimmer or flicker because the video is interlaced.
You can reduce this by using the De-interlace Filter but the overall quality of the image will still be poor.
The only way I ever achieved reasonably sharp results was to show no more than half the screen at any one time. If you do that your results will be OK.

HDV image quality problems on capture

Hey gang! I just got my first tape shot on a Sony Z1U, and I'm trying to caputre with the M10U deck. My problem is that the footage looks fine in the camera, and looks the same when played from the deck (via component video) to two different monitors. When I capture, the image is remarkably different - darker, with muddy colors, lousy skin tones. I'm using the HDV 1080i easy setup, and I've recalibrated my cinema display to its default (calibrated was even worse!) I've also tried using HDVxDV to capture, and iMovie to see if there was something screwy with my capture settings. Any ideas?

The computer monitor is the LAST thing you want to use to judge your image quality. It will never give you a true representation of what your footage looks like:
Shane's Stock Answer #2:
ONLY JUDGE THE QUALITY OF YOUR MATERIAL ON AN EXTERNAL NTSC MONITOR, OR AT LEAST A TV.
1. Disable overlays on the canvas
2. Make sure you've rendered everything (no green bars at the top of the timeline
http://docs.info.apple.com/article.html?artnum=24787
DV (and especially HDV) footage requires large amounts of data and many computations. In order to maintain frame rate and be viewable at a normal size, only about one-fourth of the DV data is used in displaying the movie to the screen. However, the DV footage is still at full quality, and is best viewed thru a TV or NTSC monitor routed thru your camera or deck.
HOWEVER...that is the stock answer for DV, but helps explain why your quality looks bad. Unfortunately, HDV does not allow you to view your timeline in real time like DV does. HDV, being HD, requires an HD card and monitor solution:
Shane's Stock Answer #25 - HDV external Monitor Viewing
To view HDV on an external monitor you are going to need to purchase a capture card, like the ones Decklink or AJA offer. They will both play out HDV in real time. The catch is that you cannot view this on a regular TV or NTSC monitor. Since this is HD, an HD monitor will be needed.
HDV cannot be played out of FCP via Firewire because it's Long GOP structure is too taxing on your processors to spare the system resources needed to drive an external monitor.
(Wow, two Stock Answers in one post. I think this is a first.)

Poor image quality? Why do Jpeg's look so bad?

If anyone has tips on how to improve the image quality of jpeg's in acrobat.com I'd really like to hear them. I've edited the images in Photoshop (CS4), exported them as jpeg's, and inserted them into my acrobat.com presentation. They look horrible, and there are many artifacts. If I insert the same image into Powerpoint, they look considerably better, but I'd prefer not to have to use it. Is there an image quality setting that I'm missing?
Thanks for any help,
Rob

Hi Rob,
Thanks for posting - and sorry you're having trouble. It sounds as though the image's quality is suffering because it's being down-sized upon insertion. In Presentations, any images larger than 1024 on a side are resized to fit within a 1024 bounds (we do this to optimize performance - important for a web application).
Here are some tips from one of our fine engineers:
For the best looking images, pre-scale your images to fit the size of the presentation before you upload them; for reference, the slide canvas is 720 pixels wide and 540 pixels tall. Any image larger than those dimensions is larger than it needs to be on the client so you and your audience are downloading more data than they will ever see. If you resize your images to fit the size it will appear on the screen, you will have a better looking image.
The choice of image format makes a difference at this scale as well. For image with smooth transitions like photographs of landscapes, jpeg is a good format. For computer generated diagrams like charts, or images with lots of details like text, PNG is a better format.
It is important that the image be scaled to the appropriate size before uploading because the server will recompress any image it needs to scale using JPEG compression. So if you are uploading a PNG image with transparency, you will loose any transparency effect if the image is large enough to require scaling on the server.
I hope this is helpful, Rob. Please let us know if you have any further questions.
Best regards,
Rebecca

Poor Image Quality In FCE With Photoshop Imports

I'm using scans created in Photoshop in my current FCE project, and am extremely disappointed with the image quality. All scans are 72 pixels/inch, 720x534 pixels (changed to 720x480 for import), sharpened with Unsharp Mask. In Photoshop, they look terrific. Imported into FCE and viewed in the viewer, they look terrific. When dropped onto the canvas to add to the timeline, suddenly they look like crap. The sharpness is gone, the edges are pixelated, and most are rendered unusable. What happened? Can I fix it? Thanks in advance.
Dual 2 GHz PowerPC G5 Mac OS X (10.4.5) FCE 1.0.1

Really!? I'm surprised, as those numbers come from the Apple Pro Training Series book on FCE. But ok, I'll redo my images at 720x540. I should still make a version at 720x480 for import, to avoid "squeezing" the image, right? Should I avoid sharpening the image at all, or just cut back on the amount (or does this depend on the image)? When you say "the canvas is a reduced display output," do you mean that this reflects the compression that occurs with the DV format? Thanks, Tom, for your help.

Image quality reduced when scaled down on black background

I am trying to view two tracks at the same time so I have scaled them down. Once I rendered them, the quality was horrible and then I changed the background to checkerboard instead of black, which worked, but I would like a black background for viewing, so how do I fix the poor image quality problem?

I'm guessing you're making this judgement in the Canvas. You really can't. Check it on an external CRT, and make sure your render settings are all set to their highest. Just because it plays back or evven has a proxy render doesn't mean you're seeing its highest quality.
Are you saying that when you put them over a different background the quality improved? I don't know why that would be, bbut if it works then try putting a slug on V1 as a black background.
Or by checkerboard you mean you set the Canvas to a different mode...?

Trouble with image quality upon transfer in CS5

when dragging a high resolution JPEG image onto the canvas (958 px by 480 px) I'm working on, this message appears:
"the target document has a different depth than the source document. this may result in lower than expected quality..."
does that mean the quality of the image i'm using will be compromised? how do i prevent that from happening?
Thanks!

i found that converting it to a smart object before dragging doesn't compromise the quality as much. is there another way around this?
Is Photoshop > Preferences > General > Place or Drag Raster Images as Smart Objects checked?
what is Camera Raw?

Reduced Image Quality

So... I've perused through looking for help on this, and it seems like many people have had this problem, but I'm not sharing in their successes.
I have an image (a group photo) that I'd like to include in a sequence (DV NTSC), and when I view it in the browser it looks stellar, but when I edit it into the timeline it looks pixelated and blurred.
I know that you're not supposed to judge image quality by looking at it in the canvas, but shouldn't an EXPORTED DV sequence look better? It doesn't.
Rendering the image doesn't help (any rendering should occur when the whole sequence is exported anyway); it clearly has something to do with the inherent reduction of quality when the high-res image is edited into my DV sequence. I've tried editing the image to an uncompressed sequence as a test with no luck.
I have some titles whose quality is also degraded when they are edited into the sequences (and exported).
I'd love some help with this.

DV degrades the photo. If you have a 3000x2500 image at 600dpi, you drop it into a FCP DV sequence it becomes 720x240 at 72dpi, and adopts the DV 5:1 compression.
Nothing you can do to avoid this...except for when you lock picture then take your DV sequence, drop it into a DV50 or uncompressed 8-bit timeline and render. Your picture will look much better.
But that only works if you are making a DVD. If you go back to DV tape then there is nothing you can do.

Help displaying an image using the canvas!!!!!!!!

Hey guys
I don't know whether I am not grasping some concepts well.I have been going mad trying to get the code working
Here is the code

int y = getHeight();
g.setColor(255,255,255);
g.drawImage(currentimage,x,y,g.TOP|g.VCENTER);
public void run() {
repaint();
I know for a fact that the Canvas class 's paint method is called by the system and not the application. This poses a problem for me because I am not sure how to pass the image to the piant method, so that it can be painted.
When I run the program(using J2ME wtk04), this is the outcome.
Image created succesfully
Canvas instiatiated successfully
null
Here are my questions
1) when is the paint method precisely called by the system?after a reference to the canvas class is created?
2) is it wise to create the image when instiating the canvas class?( initially created the image using a separate thread)-when sould the image be created?
3)how to let the application know when to use the image when painting the display area?
I am just trying the logistics here. It is very crucial to me to understand the bolts of this as the core f my project fouses on the man machine interface development.(For the project, the cilent application is quering for the map using HTTP)
I use a png file of size 161 bytes. Is that too big for testing purposes.
I would all the help that I can get. thanks in advance

1) when is the paint method precisely called by the system?after a reference to the canvas class is created?
After the canvas is set as the current display, and after that, after the repaint() is called.
2) is it wise to create the image when instiating the canvas class?( initially created the image using a separate thread)-when sould the image be created?
It's better to create the image in the very begining of the program e.g. in the midlet initialization. You can call the created image as often as you like later on
3)how to let the application know when to use the image when painting the display area?
you have to tell it :))
you can use if-then, switch, or anything else
and you can use clipping too

Firefox mage quality and resolution was superb when I used XP and Vista. Now that I have Windows 7, however (with the Firefox 3.6.3 version), the image quality and resolution is poor. Please help me!

I am using the Firefox 3.6.3 version with my new Windows 7 operating system. When I used all the previous Firefox versions in my XP and Vista operating systems, image quality and resolution was excellent! However, now that I have upgraded to Windows 7 and Firefox 3.6.3, the image quality and resolution is poor (unacceptable for downloading purposes).
== This happened ==
Every time Firefox opened
== I first activated my new computer and installed the Firefox 3.6.3.

All my images are pixelated in firefox 3.6.3
http://www.dcgdcreative.com
Not only on my site but on most sites I view.
The issue is not solved by resetting the zoom text view (ctrl+0)
The issue is not resolved by starting in safemode with add-ons disabled
The problem seems to only affect .jpeg files and only on Windows 7 on my desktop; as I have viewed several sites using windows XP with my laptop, no issues.
I had the same issue with IE8 and was able to fix the problem with by setting up the compatibility view for all sites. Issue fixed no problems at all. But nothing similar for firefox?
Whats the deal?

I want to make a copy of slide show create from my own photographs and with a an audio track behind them. I have carefully followed the iDVD tutorials and burnt the result to a disc but image quality is very poor. What is wrong?

I want to make a DVD of a slide-show with an audio track behind the photographs. I have carefully followed the iDVD video tutorials but the result is far from satisfactory. The quality of the images on the resulting DVD are blurred and indistict although the original photographs are of a very high quality. Where am I going wrong? Would I have better results from a different program than the inbuilt iDVD and if so so what programs have others found to be better? I should be grateful for some expert guidance.

Hey Falcopebo,
Thanks for using Apple Support Communities.
Looks like you have image quality issues when using iDVD to burn.
iDVD 7.0: Burned DVD has interlacing, pixelation, or image quality issues
http://support.apple.com/kb/ht4078
A standard DVD made by iDVD is made to the standard DVD resolution of 720 X 480, which is smaller than most HDTVs and monitors. When expanded to fit the entire screen or monitor, the image will distort slightly due to upscaling to fit the screen or monitor.
Have a nice day,
Mario

HT1338 What is the best online storage for photos. Specifically one that allows the original image quality to be downloaded should your hard storage goes belly up

What is the best online storage for photos. Specifically one that allows the original image quality to be downloaded should your hard storage goes belly up

I'd put them on an external hard drive(s) and burn them to a DVD as well (at least 2 - 3 copies on different drives/media); I prefer having control and a local solution instead of relying on a server and the possibility of someone (who shouldn't be) downloading my work.

How can you find out an individual image size from multiple images on a canvas

This is probably a really really simple question but I can't for the life of me find how I can find out an individual image size from multiple images on a canvas. eg I have 3 photos i want to arrange 1 large and the other two next to it half the size. How can I edit individual image size on the canvas as when I select the image on a sperate layer I want to resize it just resizes the entire canvas and not the individual image
Thanks

I want to know they exact dimensions though. You can get them by dragging to the 0,0 corner and then reading off of the ruler scale on the sides but its fiddily as you have to zoom right in and work it out. I know in photoshop there is a ruler but is there any other way in Elements?
