Uncompressing .Z files

Has anyone had any luck uncompressing .Z files (Old UNIX compression format)? Here is what I've tried:
http://www.ni.com/example/28662/en/ - which is LV5... I wasn't sure this was the right solution anyway.
OpenG ZLib - Can't get it to open a .Z file. Returns "Not Found" which makes me think it doesn't support .Z files. Documentation on that library is sparse.
Base zlib DLL (http://www.zlib.net/) - Looks like it might work, but "Import -> DLL" seems to crash LabVIEW every time. I'd have to go through the .h files manually and figure out what parameters need to be fed in to the function calls. I could do this, but... I'm hoping somoene has done this before and has a canned solution before I spend 3 hours rummaging through header files
Thanks!

That was the other program I have done the sytem exec with. 7Zip is so much better.
One possible way around your issue is to just include the 7zip executable with your program. It can just sit right there inside your support directory and IT needs to know nothing about it. No installing it. Just copying the latest executable into your project. I have not tried that myself (my IT loves 7zip), but I have been told that it works.

Problems with large frame uncompressed AVI files in QT 7 player

I have just recently gone from QT Pro 6.5.2 to QT Pro 7, mainly because of the HD support.
I have a dual boot system with QT 7 on Windows 2000, and QT 6 on Windows 98SE.
I am having problems playing uncompressed AVI files in the QT 7 player, apparently if the frame size is large (in the example case 688 x 516).
Sometimes I just get "error 108 unknown error" pop up when I try to load the file. Sometimes the file loads but will not play except in short bursts of movement every now and again as it moves along the timeline. Sometimes the file plays, but with one or more broad black lines across the image!
All the problem files play perfectly in QT 6.5.2, but will not play in QT 7, which should surely play them better, not worse!
Can anyone make any suggestion as to what's happening?
I've uninstalled and reinstalled QT 7, which made no difference. I'm sure I don't need any extra codecs, as QT has always played RAW AVIs without anything extra before.
Thanks in anticipation, Dave.

Poor image quality for uncompressed .jpg files

Hello,
I am importing in uncompressed .jpg files that I have made
smaller in Photoshop, but didn't modify compression. This is the
original format at they are stock photos. My project preferences
for jpg files are set to 100. When I import them and publish my
project, the image quality is sub- standard where areas of the
picture are blurry and fadded.
Since the images started as jpg files, recompressing them or
saving them as bmp files which Captivate likes, is not an option.
Any help is greatly appreciated.

Hi Rick,
I didn't notice the slide property dialog that is set to
default to Standard. This should help. thanks.
By the way, I am still having major problems with the issue I
emailed you directly last week with all the attachment files. I
know you are busy, but if you have time to revisit, I'd appreciate
it. I don' t have a solution and need to deliver next week.

Is it possible to export uncompressed .avi files over 4 gigabytes?

I want to export my 70+ min movie as one uncompressed .avi - file with FCP
but it turns out only 4 gigabytes of data (35-50 seconds) are visible in the exported clip. The rest is black.
How do I get around this problem?

The drive is mac standard (not FAT32) and I have checked + confirmed that the drive can take files larger than 4 gigabytes.
The .avi file I export IS the right size (200+ gigabytes).
Even though the audio and video doesn't show up after a certain point.
I use Quicktime conversion - avi (compressor : none, quality: best) etc.
I've tried saving with and without sound (48khz 16bit uncompressed)
When I save without sound, the exported file contained a little bit more video data (a few more seconds)
which supports my 4 gig limit theory.
I just want to export the movie in it's uncompressed state
for editing on a PC (premiere cs4)

Working with uncompressed XFL files and source control | Learn Flash Professional CS5 & CS5.5 | Adobe TV

Use the Flash uncompressed XFL file format with a source control system to enable designers and developers to collaborate on Flash projects. Contributors can edit different assets simultaneously and see updated assets as soon as they are checked in.
http://adobe.ly/x0GHI4

This is a great overview of sequential use of source control with the xlf format. However, typically in a team setting, team members are working at the same time. Our team has found that many of the xlf files have one or more timestamp related entries that get updated even when no functional changes have occurred. This is particularly true of DOMDocument file, which timestamps changes, marks library elements as expanded or not, and tracks a published history. All of these changes conflict with anyone who is simultaneously working on the xlf. Any tips on how to deal with these issues?

Add option for lossless uncompressed RAW files for A7r

I'd like to see the option for lossless, uncompressed RAW files for those of us who want it vs. the current situation of only having the option of lossy compressed RAW files (which in some instances, can exhibit posterization). I think this is a logical option for a camera of the A7r's calibre. If this option can be incorporated via firmware update, all the better. If it's a hardware issue, hopefully this is addressed in the next iteration of the camera.

Honestly, this is pretty deceitful marketting on both the Sony A7 and A7R literature. both promote the use of 14 bit RAW encoding as a feature of the two sony cameras, however, they are really 11 bit + 7 bit compressed lossly RAW formats, delivering no where close to the same tonality of 14 bit true RAW. in no sony literature that i could find, is it mentioned that it's lossly. this is accurate? Not even close. 14-bit RAW output for rich tonal gradation 14-bit RAW image data of extremely high quality is outputted by the a7. This data fully preserves the rich detail generated by the image sensor during the 14-bit A/D conversion process. When developed with Sony's Image Data Converter RAW development software, these images deliver the superb photographic expression and rich gradation that only 14-bit data can offer. I was going to purchase two A7R bodies and move my canon gear over to Sony ..until really all this came out. I'm hoping as well as the OP that a firmware upgrade comes out.

Exporting uncompressed Quicktime files

I have been asked to create an uncompressed Quicktime HDV file of a short film that I edited in Premiere Pro CS3... Having done some research, it appears that this is not as easy as it at first sounded. I know you can export an uncompressed .AVI file, but I can't seem to find a way to export an uncompressed Quicktime. Is there a codec/plugin avilable that would allow me to do this, or can I export the .AVI and convert it to an uncompressed Quicktime file somehow?
Any help is very, very greatly appreciated.

Export cannot crop selectively, it's all or nothing.
You need to make your edits such that the program monitor shows you what you want to see. If you don't see what you want in the program monitor then it will not magically change when you export.
If you don't want the footage to be "bigger" then don't scale it up. If you want to hide something use other editing techniques like masking or picture-in-picture.
You will find links to many
free tutorials in the PremiereProPedia that will quickly show you how things are done in Premiere Pro.

AVCHD to Uncompressed Video File Conversion Factor

I have a Canon HF S21 camcorder and I'm looking for a conversion factor from AVCHD to Uncompressed Video Files when filming in maximum video resolution of 1920 X 1080. I want the conversion factor to size an eternal firewire hard drive for editing my videos in Final Cut Express.

Whilst I have no experience of AVCHD other than a few clips from the DVD in Tom's book, I have used ProRes and Apple Intermediate Codec which is what all AVCHD is converted to before editing in FCE/FCP and the USB 2.0 Hub and Hard Drives combination has worked flawlessly.
Of course, until I have actually used an AVCHD camera I won't be able to comment either way with any certainty.
For a while I have been wondering whether PAL or 25fps based cameras act slightly differently from NTSC or 30fps ones with regard to ease of editing my way.
Here's an example I posted some time ago, though be aware that the image has been reduced to 1280x720 and a very low data rate was used in order to keep the file very small because of a monthly cap on my internet use.

Deleting the uncompressed video file once m2v and aif have been created

When I create a dvd then close the project.
I then later delete the uncompressed video file captured from tape.
I reopen DVD studio pro and it tells me that it cannot find original file.
I tell it to used m2v encoded file as new video file and aif encoded file as new audio file.
But i am then given an error message and these two files disapear.
Can anyone help me out. Surely i should not have to keep the original captured video file for every dvd I want to make. The idea surely is that once DVD studio pro has made m2v and aif files then the project should be able to use those to create any further DVD of that project.

I've still never seen any problems with a single video track and uncompressed audio.
I won't argue that it never happens to anybody, of course, but I've made DVDs for a lot of people, and usually the only problems I hear tend to be a problem with their brand of player not being able to recognize the media. Those are relatively rare and almost always has to do with cheaper brands of DVD players. If they can get it to start at all, I haven't heard of any trouble with playing the whole thing.
I would like to know if that's the problem I had with trying multiple video tracks, though. DVDSP would refuse to even finish the build. It would start to mux, then partway through, say the bitrate was too high and abort. It was a long time ago, but I would've been using uncompressed audio and probably fairly high bitrate video (3.2Mbps, possibly even 3.5). Seemed stupid to me; I would've thought the muxing would be a smart enough design so that only the video and audio tracks in use at any given time (one video, one audio, one subtitle) would count toward your maximum allowed bitrate.
But that brings up another point you guys might try. I heard people mention 3.5Mbps. I use 3.2, and I don't see any noticeable difference in the quality of the video. But switching from uncompressed audio to ac3 definitely is a noticeable (downward) difference, at least using the stock Dolby 2.0 encoding preset included in DVDSP4 / Compressor 2 and a standard stereo (2-channel) source. I did several different tests where I encoded the audio both ways and burned a test DVD with multiple audio tracks, switching between them to compare. Even normal conversations on the ac3 (Dolby 2.0) track sounded quieter and less dynamic, and there was (naturally) an even more noticeable difference in any kind of music.
So you might give that combination (3.2Mbps video with uncompressed audio) a try in the future, especially if you're picky about the audio. If that fixes the problem, I think it's a reasonable sacrifice since the audio difference is more severe. Basically, if you're doing a professional enough job that the difference in video between 3.5Mbps and 3.2Mbps is important, then you should already be doing a professional 5.1 audio encoding from individual channels anyway.
BTW, I have my 3.2Mbps labeled "120min", since that's about what I can fit on a DVD with uncompressed audio. My other often-used settings are 2.8Mpbs for 135min (three hour-long TV episodes with commercials cut out), and 2.0Mpbs for 170min. (And I can't remember for sure, but the 170min may even be a slight overestimate, so be careful of cutting it too close if you use those settings.) I usually don't even notice a video quality difference with 2.8Mpbs, though I have only used that with a less-than-pristine source anyway, so the lower bitrate isn't the bottleneck for quality in that case.

Converting uncompressed AVI files for FCP?

I recently had 30 reels of old 8mm film footage from the 50's and 60's converted to digital and I now have a hard drive with all of the footage converted to uncompressed AVI files. These are extremley large files as one 2 minute and 38 second clip is 4.45 gigs.
I want to bring them into Final Cut Pro to edit them but retain as much quality and picture as I can. I am going to use Mpeg Streamclip to convert the AVI files to quicktime Mov. files but what compression setting and frame size should I use when converting them to Mov. files for best results? As far as frame size, should I use 648 X 486 4:3 aspect ratio or 720 X 486 unscaled?
Thanks in advance for any advice.

Given the material, standard ProRes or even ProRes LT (if you have FCP v7) is fine.
ProRes HQ is intended for 35mm film out and/or 2k video. It is a waste of file space and processing overhead for your purposes.

Handle Uncompressed Quicktime Files?

Hey All,
Total newbie, here. So please excuse if this is a dumb question.
I work a lot in commercial production, but obviously, only in the very non-technical end of it. I've been getting a lot of samples of my projects in an AVID-generated uncompressed quicktime format. (The kind where the pixels are round as opposed to square, so if you try to play them in quicktime, the proportion of your screen area gets squished down a bit.)
Here's my question. I know I can bring these into Final Cut Pro and it can translate the pixels so the screen area appears at its proper size. Can Final Cut Express also handle these files?
I tried to figure this out by looking at apple.com/finalcut but couldn't really figure out the answer.
Any info would be greatly appreciated. Thanks...

Cool. That explains a lot.
I'm getting the files from editing houses. They are uncompressed quicktime files. Don't know if there's a more specific description than that. Been trying to transition away from keeping digi-beta copies of everything. The files are coming to me burned on a DVD and then I just copy them straight into my computer.
Don't know what codec is being used. I don't actually have the files on my person at the moment, otherwise I'd check.
Anyway, it sounds more and more like FCE is not the right answer for me. Usually, I have editing places take my uncompressed files and then have them convert them into dv files. Those, I can just bring into iMovie to do what I want. Was trying to avoid having to call in the favor to have the editing places convert them and was hoping to use FCE to do it all myself. But that isn't sounding possible for a lay person like myself.
If there's anything else you think I should know I'd love to hear it. Thanks a lot. You've been really, really helpful.
