Quality loss when merging files using QT7

I used QT7 to merge two video files using the suggested method of selecting all of the second file and pasting into end of first file. Worked fine, but the new file is barely larger than the first. Am I losing quality? 25MB + 15MB = 26MB instead of 40MB
Did you "Save," "Save As...," or "Export" the "combined" data file? Were the source files previously trimmed "by reference" at any time?

Serious quality loss with MTS files and iMovie '11

Hello,
I have some issues with my brand new Panasonic HDC SD700 (a full HD camera)
I experience serious quality loss when I use iMovie to create a movie.
I did some tests, but still puzzled int this world of codecs and formats.
Maybe some of you can help.
I have made a short shot of 450 sec with highest mode (1080p 24fps)
It show is finder as a .MTS file size 99MB, I'm very happy with the quality when I play this with VLC.
iMovie turns this file into a .mov file with 635MB size, in Apple Intermediate Codec, Linear PCM, Timecode. This quality is already poor compared to original MTS file.
No wonder that the output file (select 1080p H.264 codecs) results also in unacceptable quality.
I'm running latest imOvie version with all updates etc.
I have no idea were to look to solve this issue. It is quite annoying since I have invested in a top Cam recorder. Not sure is Final cut express will sure the issue either.....

I have made a short shot of 450 sec with highest mode (1080p 24fps)
Have you tried shooting at the PAL standard of 25fps? I checked the specs for your Panasonic but didn't see any mention of a 24fps mode, but most reviews seem to miss mentioning the shooting modes. If you did indeed shoot at 24fps, did you choose this frame rate when importing to iMovie '11?
I export as 1080p (same as original. My output is a bit blurry and colors are a bit pale.
Did you use the 1080p preset under Share to Media Browser, or Export using QuickTime? If the latter, be sure to select an appropriate data rate - if set too low this may result in poor quality output.
And yes you are right I'm using IMovie '11, quite confusing that '11 means version 9.0
Yes - very confusing! In the forums, iMovie versions are generally referred to by their year number, not version number. It's a pity that we have version 9.0 (iMovie '11) and iMovie '09.
Glad you liked the video - it looked very clear on YouTube at 1080p Full Screen, at least to my ageing eyes!

Is anyone else experiencing this? Adobe Acrobat Pro 9.4.5 works for while when merging files into a single PDF but then starts crashing when saving the mreged file. (MacBook Air, 10.6.7)

how big is the PDF in MB (more or less according to the loose pages)?

Quality loss when converting pro res to mp4

Hi
I have a problem with the workflow from After Effects to a final .mp4 video.
I have been editing time lapses in After Effects, and exporting them as Pro Res HQ- all good so far. However, I can´t seems to be able to convert the Pro Res file to a .mp4 (or quick time .mov for that matter) without significant quality loss. This happens if I convert using adobe media encoder, or if I import the Pro Res files to Premiere and export through Premiere.
However, if I import the original JPG/TIFs to Premiere, and export using the exact same setting- I get a better result. Also, when I have uploaded the original Pro Res HQ file to vimeo, they do a much better job of converting it than Media Encoder or Premiere do when I convert to .mp4 (I´m aware that it is not the same conversion, but still..).
So my conclusion must be that AME and PP does not convert from Pro Res to other codecs very well? I have to work on my files in AE, and I need .mp4 as the final product (requirement for uploading to a stock site). How do I do this without getting lower quality video than if my workflow and export was only in Premiere? After Effects does not render out .mp4 very well it seems...
A screenshot showing the setting I use when exporting from PP or AME. The settings produce a good result when exporting other files from PP, but not the Pro Res files I have exporter from AE.
Thanks for your input!

Figured it out after testing various settings. I read an article describing the keyframe interval setting at 1 as the best option- clearly that was wrong! After searching I found a better description of keyframe interval: "Having too many keyframes severely reduces quality, because the efficiency of reusing image areas from previous frames is completely lost at each keyframe – the encoder has to "start over" at every keyframe. Therefore, we want as few keyframes as possible to achieve the highest quality for the given target bitrate."
Tested with keyframe settings 25 and 75- both seem fine.
Thanks for the feedback

Major Quality loss when editing in Iphoto 09

Hi,
I am a new user to Imac and Iphoto and I saw that when I edit an Image in Iphoto, I loose a lot of my original data.
I have found that I can return to the original picture, but I wish to edit (especially using the CROP function) then print the Image on 20x30 cm size and therefore I need all the quality I can get.
When I Crop either JPEG or .RAW formatted images (for example 10 MBytes in size) even if I select the COMPLETE image, I am left with only 4 or 5 Mbytes of data.
It gets much worse when I really Crop a part of the picture.
A 12 Mega pixel photo should supply sufficient data to cover a complete wall, but for some reason a lot of quality is lost when I use any of the editing features.
Am I doing something wrong ?
Should I change any of the settings ?
Thanks for your advice

Welcome to the Apple Discussions.
the only difference is that Iphoto took my quality !!
Are you basing the "quality" loss on visual appearance of the photo or on the resulting size of the jpeg file? If it's the latter that is really not an accurate method. True, some information is lost with a jpeg edit and save (only the first edit in iPhoto results in additional jpeg compression) but, in my experience, you would have to print a VERY large print before seeing any noticeable image degradation. I've compressed jpegs as high as 60%, i.e. a quality setting of 40, and for most all uses up to 5x7 prints haven't seen noticeable image degradation. However, I realize image quality is subjective and open to individual interpretation.
So unless you are visibly seeing image degradation I wouldn't worry about the file size reduction, especially in iPhoto as it's compressed only once no matter how many edits are made and saved. Apple uses a compression algorithm that gives the best image quality for the amount of compression it uses.
The following is from the Usernet FAQ site article "JPEG image compression FAQ, part 1/2':
Subject: [4] How well does JPEG compress images?
Very well indeed, when working with its intended type of image (photographs and suchlike). For full-color images, the uncompressed data is normally 24 bits/pixel. The best known lossless compression methods can compress such data about 2:1 on average. JPEG can typically achieve 10:1 to 20:1 compression without visible loss, bringing the effective storage requirement down to 1 to 2 bits/pixel. 30:1 to 50:1 compression is possible with small to moderate defects, while for very-low-quality purposes such as previews or archive indexes, 100:1 compression is quite feasible. An image compressed 100:1 with JPEG takes up the same space as a full-color one-tenth-scale thumbnail image, yet it retains much more detail than such a thumbnail.

Quality loss when playing DVD authored in Encore on a HD flat screen

Hi,
I authored a DVD in Encore and i noticed that when i played it on my pc it looked fine but when played using a DVD player on a HD flat screen and projector there is a significant quality loss- the image became pixelated and glittery. I tried playing 3 other professional videos and they were all fine. Something must be wrong in the way i am authoring my video. The encore file is set to 720x576 at 25fps. I created a .psd menu page to match these dimension and besides the movies, both the menu page i created and the menu templates that are already there in the library when you buy the software, look glittery when played with a projector or HD flat screen and projector. Any suggestions?
Thanks,
Eric

Lack of control over users players/TVs is a problem. And you can try to provide some instruction.
You are right to test your product to see if you have a reasonable chance of your DVDs looking good.
First, test them on a DVD player and a standard definition TV. Your test on the PC is not sufficient. If they do not look good here, you have problems somewhere in your workflow. (I suspect this is the case. In my tests below, I see no flashing or issues like what you describe.)
If okay there, you need an upscaling DVD player to test on your HD TV. You should also explore the options on that TV for setting size.
For example, I just put a DVD in my Bluray player (hooked via HDMI to an HD 1080p TV). I can set the player and the TV separately to various resolution settings. Forcing the player to 480 and the TV to Normal gives a picture that looks like the original version, using a regular DVD player set to a 4:3 TV. But when I set the Bluray player back to "HDMI auto" (for the resolution), and the TV to normal, I see a pretty respectible picture.
I did the same sort of test using a regular DVD player via regular AV cable. Discovered I had it set to the wrong TV type! I could not see a lot of difference in the picture, even if I stretched it. (It was distorted, of course, but not pixelated, just not the crisp look of HD.)

Gaps inbetween letters of full words when Merging files to single PDF (Adobe Acrobat 9.0 Standard)

I've raised a Bug Report although it says that I may not be contacted so thought someone else might have encountered this issue and hopefully knows what causes it and how to fix. Any advise would be greatly appreciated. Heres a copy of the Bug Report details...
******BUG******
Concise problem statement:
An intermitent issue is occuring when merging multiple files into a single PDF in Adobe Acrobat 9.0 Standard, the resulting PDF file has gaps inbetween the letters of actual words. For example the word "document" may appear in part of the PDF as "doc ument". This seems to affect various parts of the final PDF file.
Setup: Windows XP SP2, Adobe Acrobat 9.0, Microsoft Office Standard Edition 2003
Steps to reproduce bug:
I am currently unable to replicate the issue on demand but this has happened three times since installing Adobe Acrobat 9.0 a month ago. The most recent occurance happened when merging 6 Microsoft Word Documents. It is a real problem due to the fact that every PDF created needs to be carefully checked and in some cases these PDFs have hundreds of pages.
The steps used are:
1) Open Adobe Acrobat 9.0
2) Click File
3) Combine
4) Merge Files into a single PDF
5) Add Files (select the required files)
6) Combine Files (which then processes and creates single PDF)
Results:
A single PDF is then created and as mentioned is occasionally affected by this issue of random gaps appearing within words.
Expected results:
A single PDF with the same formatting and layout as the original files.

Thanks for the response.
I have checked though the Word documents that were used in the most recent merge. They don't have any spaces at these areas or strange formatting. I turned on the Show/Hide option to confirm if there was anything odd but I could not see anything. The formatting (Ctrl+D) shows the default font Arial, Regular, font 12.
The interesting thing is that if it occurs and attempt another file merge the gaps are no longer there. Which makes me think this is unlikely to be the documents and formatting being used and more likely to be a bug in Adobe Acrobat.
Is there anything else that might be of use to know?

Quality Loss When Importing Video into Timeline...Any Ideas??

Hey all -
I'm fairly new to CS4, so excuse me if this question is a little dumb.
I've offered to edit a friend's actor showreel to familiarize myself with CS4. He gave me a bunch of HD clips: they're .MOV files, and are 1920x1080 and 23.976fps.
I can import a clip and drag it into the preview screen in the middle: it looks fine. However, when I drag it onto the timeline, it suddenly looks faded and blurred. It's not horrible, but it loses the vibrancy of color, the sharpness and the contrast of the original clip. A lot of the quality is gone.
I've tried opening the project with a number of different settings, no difference. I thought it might look OK when I exported it, but it looks just like it does on the timeline monitor: a little washed-out, blurred, just not as nice as the original.....
I'd hate to present it to my pal looking like this, can anyone suggest a solution? I tried everything I could think of already....
Thanks!!

Hi Hunt -
many thanks for your reply. I've spent the last couple of days trying to follow your advice and do more research.....still no luck.
Firstly, I upgraded my OS to Windows 7, thought it might help for some reason. Didn't. I downloaded a bunch of codec packs.
Gspot reports:
Codec: AVC1
Name: H.264
Codec Status: undetermined
So I'm basically running through all the possible output formats, but really it doesn't seem to be an encoding problem: the quality loss happens as soon as I move the file from the preview screen to the timeline.
If you have any othe suggestions I'be very pleased!!
Thanks
Bruce

Quality loss when choosing Widescreen project settings. (raw footage is widescreen)

Hi all,
I am using Adobe Premiere Pro CS4.
I shot some footage in 16:9 format. when I view the original video it looks fine. Here is the problem: When I create a standard format video project in PP, it looks fine, but that cuts off the sides of the footage so of course I want to use the 16:9 format. However, when I create a new project and choose that 16:9 format, the video looks what I would call "fuzzy" in the preview window. Also when I export the video, it has the same problem.
I shot in 16:9 Standard HQ 570p.
I would appreciate the help!

>16:9 Standard HQ 570p
I have never seen 570p... what camera?

Report back with the codec details of your file, use the programs below
For PC http://www.headbands.com/gspot/ or http://mediainfo.sourceforge.net/en
For Mac http://mediainfo.massanti.com/
Once you know exactly what it is you are editing, report back with that information... and your project setting, and if there is a red line above the video in the timeline, which indicates a mismatch between video and project
Also... if you do have HiDef and you are exporting to Standard Def, there WILL be a loss of quality

Quality loss when exporting to quicktime (no conversion)

i'm trying to export a fully rendered project in final cut pro (6.0.2).
i'm using the option i always used:
"export -> quicktime movie..." (not "using quicktime conversion")
the idea was to convert the movie later to h.264 (using the quicktime pro player).
normally this always gave me a quicktime movie with ± the same quality as when played directly in final cut.
no difference whether exporting as self-contained movie or referenced movie (besides the result file size of course).
only, now it's different, see here (quicktime player left, final cut right):
the text (done using LiveType) is displayed in completely unusable quality. (difference in color etc. doesn't bother me right now)
where does that come from? in final cut i don't see this rendered quality anywhere...
i also tried:
deleting the render cache, rendering the project again, no difference
export -> quicktime movie, "self-contained" or referenced movie, no difference in quality.
i didn't have this problem with the same project some months ago. back then i probably wasn't running 10.4.11 and quicktime 7.4.1.
any idea what to try?

There is no quality lost.
The default of QuickTime player when showing DV is to display 1 field and double height the image. This is to avoid interlace combing on the non-interlaced computer display.
IF you type cmd-j and bring up the info for your clip, thusly:
In the lower right corner you'll notice the High Quality flag:
Setting it will take you from this:
to this:
Alternatively, you can go into the QuickTime Player preferences and set the default there:
Make sense?

Motion Graphics quality loss when encoding to DVD

I have completed a logo reveal and movie titles for our short film that we will be authored to DVD. I used AE CS4 and created the compositions as 1050x756 PAL square pixels.
The uncompressed AVI renders look amazing. However, when i encode using MPEG2-DVD straight from AE there is a big hit on quality. I understand that encoding is about compressing and that we need to expect a certain amount of quality loss. But the text is especially bad.
I read somewhere that saturated reds are not particularly well handled by the MPEG-2 encoders. So we changed the color to a more subdued burned orange. We also remove the titles horizontal scroll on the screen that was causing excessive flickering. But there is still a high rate of quality loss on the text.
Is there any special workflow that i should be using, tips or tricks that you know of? I see some awesome intro titles on DVD and the text does not behave in this way.
Any pointers and suggestion you can give, would be greatly appreciated

Robert:
The MPEG-2 encoder in AE/AME is a very good, general purpose encoder.
Commercial DVD titles frequently use high-end, specialized encoders. This includes very expensive, hardware-based encoders.
That said, you could get better quality from the MPEG-2 encoder in Adobe applications by using 2 pass encoding. Unfortunately, the Render Queue in AE only can do 1 pass encoding. In order to use 2 pass encoding, you'd have to launch Adobe Media Encoder in standalone mode, pick an MPEG-2 DVD preset and enable 2 pass encoding.
Specialized encoders include, for example, Cinemacraft SP. It can do multipass encoding and offers a great deal of control over encoding settings. Even as a software-based solution, it's not cheap.
It's also worth pointing out that type for highly compressed media has its' set of do's and don't's. Applying a very subtle vertical blur (Reduce Interlace Flicker) usually helps. Fonts designed for high-resolution media (most families with serifs) need to be used at large sizes, or use sans serif typefaces for smaller sizes, etc.

Can I control filenaming when archiving files using the file adapter?

Hi folks,
Is there anyway to control the filename used when the File Adapter writes out to an archive?
Second question, I also need to be able to pass a "filename" to the adapter from an "input file." Is there a way to do this in the file adapter?
Sincerely,
lpac

Hi,
I have done that with the ftp adapter. In the .xsl file I wrote the following after the <xsl:stylesheet version="1.0" ....> tag:
<xsl:variable name="INFILENAME" select="ehdr:getRequestHeader('/fhdr:InboundFTPHeaderType/fhdr:fileName','fhdr=http://xmlns.oracle.com/pcbpel/adapter/ftp/;')"/>
<xsl:template match="/">
<xsl:variable name="OUTFILENAME"
select="ehdr:setOutboundHeader('/fhdr:OutboundFileHeaderType/fhdr:fileName', $INFILENAME, 'fhdr=http://xmlns.oracle.com/pcbpel/adapter/file/;')"/>
<opaque:opaqueElement>
<xsl:value-of select="/opaque:opaqueElement"/>
</opaque:opaqueElement>
</xsl:template>
</xsl:stylesheet>
To use this with the file adapter, you would have to wirte file where is written ftp.
Hope this helps,

Drag and drop not working when uploading file using safari

why i cannot drag and drop any file when using safari , and what happens the file auotmatically open while i need to upload it only , extra for that , i cannot write any remark or fill a space while using website related to my work.
my work is to upload drawing files using dwf file to a website so the other parties can review and give me review , and then i reply to the remark at the same place and make meeting through the same site.
please any body can give any way to correct my mac.
latelly i installed win7 only to use it for that website , and iam now changing from mac to win whenever i want to work , this not acceptable to me because it is waste of time beside i like the mac and it working with other application but not for safari.

why ?
I'm sorry, but every OS is different. You cannot expect all features of one to be in another. Or alternatively, for similar features, be done it the exact same way.
It looks to me after a quick google search that winexplorer is basically the moral equivalent of the mac's finder to present the file system in different ways. The OSX Finder also has alternative views of the file system, i.e., icons, list, columns. Experiment with the list and column views and see if one of them are more to your liking.
As for winexplorer on the mac. I don't know if this simulates it or not but there is a program called Macintosh Explorer so check that out as well.
And finally, in the end, as I said in my earlier post, no matter what, nothing on the mac is going to change what I believe you think you can do and drop a file on a browser window and expect it to upload.
