Although the codec is called TechSmith Screen Capture, the software is actually called Camtasia Studio.
The codec name is TSCC, not TSSC.
Sorry about that...

darkflux Guest | let me get something straightened out here; you have a 1280x720 WMV file? or is it just your screen resolution (for playing the file full-screen) that size? i’ve only ever dealt with 720x480, as you mentioned, which is DVD standard size. capturing this, even with a 1024x768 resolution screen capture (my monitor’s res.), i only experience a 5% frame drop, even WITH audio. if i capture it at it’s natural size (720x480), i get no frames dropped. my specs:
Source file: 720x480p
Data rate: 8000 kbps
CPU: AMD Athlon64 3200+
RAM: 1024 MB Dual-Channel DDR 400 MHz
Hard drive: Western Digital SATA 10000 RPM, 74 GB
Capture software: Camtasia Studio (Recorder)
Capture AVI format: DivX Pro 6 (The new one), 8000 kbps, Fastest compression mode
Capture speed: 30 fps
Audio capture: PCM
Display acceleration: Auto-Off
capturing @ full-screen would take a much faster processor (especially @ 1280x720!), but depending on your intended use for the file (if any), you may not need such a hi resolution, and your PC should be able to do it the way i captured, too, if you so desire.

Cool, now we understand where the misunderstanding was. :-) Yes, I have a 1280x720 WMV file. If you’d like to check it out for yourself, it’s the Hi Def Trailer for “The Perfect Man”, http://www.theperfectmanmovie.com. If you’ve never seen a HD trailer, you’ll be very impressed at the video quality.
That’s amazing that your Athlon64 can capture 1024x768 with very little frame drop. Must be those extra 32 bits! :-) Also doesn’t hurt to have a Raptor and a gig of RAM. You have a pretty sweet system.
As a matter of curiosity, I can’t seem to capture at ANY resolution without frame drops. For example, even at a very low 320x240 @ 30fps, Camtasia will say there were 0 frames dropped, but I can SEE occasional dropped frames when I watch the video. There must be something really goofy with my system, because frames are gone for no apparent reason! I mean, seriously, how can frames go missing with only 30% CPU in use?
At 320x240 @ 30fps, it doesn’t matter what codec I use. I can even capture uncompressed. As long as the processor usage is under 90% or so, Camtasia says I haven’t lost any frames. For what it’s worth, I can even capture at 60 fps without Camtasia reporting any frame drops. But when I watch the video, I notice some tiny “skips” that are a result of missing frames.
But hey, that’s a different problem altogether. A dropped frame or two is the least of my concerns when the goal is capturing a HD WMV.
My next attempt will be as you suggest: Try capturing the WMV at a lower resolution (for example, by zooming Windows Media Player to 50% or 25%). But I have a feeling this won’t go very well. Just playing the WMV requires about 90% of my CPU. That leaves only about 10% CPU for capturing. :-( My only hope is that Media Player requires less CPU to play the WMV when the window is sized smaller. I’ll try it and see what happens.

darkflux Guest | Steve,
thx for the compliments about my PC; i built it with “working with hi-rate video files” in mind.
i downloaded your WMV and watched it a few times to see what to look for quality-wise (rather impressive, and with 5.1 audio too!), and then decided to “test-capture” it at 50% size with audio, just to see what it could do. as expected, major “frame-jumping”, well below acceptable quality.
so next i tried capturing with half the bitrate of the file (4000 kbps), with less than stellar results. no frame skip, but the quality looked closer to 1500kbps than 4000.
just then, i remembered what you’d said earlier about slowing the playback speed and it struck me that WMP 10 has JUST SUCH AN OPTION! thought it might be worth a try, so i went for it, leaving sound out for optimal speed, and have to admit it turned out rather well. the end file (after capturing and adding the audio) was about 160MB, and though there was about 2-5% frame loss, it’s not quite as noticable as the first few tries. if i hadn’t seen the original, i’d have though it was natural  let me know if you’d like to see it, and i can temporarily upload it to my website for you to download.
anywayz, just an fyi, but the “frame-drop” you experienced actually has more to do with WMP than your system. ya see, there’s this option in WMP under “Performance > Advanced > Video Acceleration” that’s “Drop frames to keep AV in sync” and if checked, you will lose frames in WMP, so that your system resources can be used for encoding instead. kinda stoopid little things that a person doesn’t think about til situations like these ; ) anyway, if you uncheck this, the video will play the same rate, regardless of what the audio is doing, thereby causing them to eventually go out of sync (hence separate audio capture). another way to accomplish this is, once WMP is running, open “Win Task Manager” (with CTRL+ALT+DEL) and right click wmplayer.exe, and change it’s Priority to “Above Normal”. you may experience more adverse results with this, but i thought i should mention it, just in case.
whew, what’s this thread about again? 
anyway, i have 2 questions for you, each out of curiosity, so you don’t have to answer them if you don’t wish to:
1. what are the “limitations” on this WMV (if you happen to know); i mean why the DRM, or is it just so people can’t open the file in a video editor. seems rather extravagant for just a movie trailer, even a hi-def one.
2. your CPU you mentioned was a “Mobile” Athlon? does that mean you’re doing all this on a Laptop? i’m amazed if you would get results at all. Mobile chips are usually designed for simply “playing” DVD or Hi-Def content (except on gaming and other “custom” Notebooks), and not capturing video. especially one this hi-res. it takes alot of juice too, so i bet it gets really warmed up! if you manage to capture at a decent rate, please let me know your settings, etc., for future reference.
in addition to what i mentioned about frame drops above, there are a few things you could try for a little extra “oomph”:
temporarily change your screen res to 1024x768. your vid card won’t have to work as hard, and there’s still enough room for your 50% sized vid to play.
shut down any unnecessary programs. this one may be obvious, but i almost overlooked my AntiVirus, and other System Tray icons.
Defrag your hard drive. your HDD will thank you for not having to jump from one end of the disk to the other
oh, btw, the option to change playback rate of the file is located in “View > Enhancements > Play speed settings”. as a side note, i am no longer able to select DivX in Camtasia, so i’m gonna try a reinstall of it (DivX).
let me know how it goes for ya.
| | | 17 Aug 2005 05:42 pm |
darkflux Guest | oh, btw, WMP doesn’t use less CPU to run @ 50% ; if anything it uses MORE, because it has to play the file AND shrink it by half. it almost makes me wonder if they didn’t make it 1280x720 to keep kids like us from capturing it

Wannabe Rep: 0Joined: 21 Apr 2005 Posts: 58 OFFLINE | darkflux,
It’s fun to talk to somebody who knows what they’re doing! :-)
I didn’t realize WMP actually had an option to play in “slow motion”. How slow can you make it play? 50%... 20%... 5%? I’ll have to try it. But first, I’m in the middle of a different experiment... Can I hack the header to make the file think it’s a different frame rate? I should be able to unless DRM protects the header too. I’m running some tests to try to figure out which bytes in the video control the frame rate.
If I can change the frame rate to any arbitrary value, capturing will be a simple process. I would even be able to make a “lossless” capture with a codec like huffyuv. If I needed to, I could drop all the way to 5 fps, or 1 fps, even 0.1 fps... whatever my system is capable of capturing without any frame drops. Then I could use VirtualDub to create a high-quality DivX or XviD encoding.
Thanks for the tip about dropping frames to keep A/V in sync. 99% of the time, I definitely want that option enabled. But for capturing, I can see that would be a problem. Unfortunately, the problems I described about losing frames did not involve WMP... it was Winamp. I was trying to capture a Sessions@AOL performance that I couldn’t download. As I watched it live during the capture, all appeared well. Winamp did not visibly drop any frames. But when I watched the captured AVI, frames were obviously lost in places. A frame-by-frame inspection in VirtualDub confirmed my suspicions. I will definitely remember that WMP option though. It could save me from future frame-dropping anguish. :-)
Your suggestion about changing WMP’s priority in Task Manager is clever. I experimented some with that in my Winamp trials and had good results. It definitely can help prevent lost frames.
I would like to see your captured video. 2%-5% frame drop is certainly far better than anything I’ve managed to do at this point. If website bandwidth is an issue for you, I recommend uploading the file to http://www.yousendit.com/
It will take forever and a day to upload the file, but YouSendIt will allow up to 25 downloads of the file, absorbing all the costs of download bandwidth.
In answer to your questions:
1.) I believe there is a general agreement among movie studios that anything released in high definition, even a short demo clip, will be encrypted. In some cases, it stems more out of a conceptual basis than out of practicality. As a matter of purpose, Hollywood is trying to reduce the spread of illegally-duplicated copyrighted material, especially when it is high-quality. A LOT of effort is being put into the encryption techniques for the soon-to-debut HD-DVD technology. Hollywood does not want the same thing to happen to HD-DVD (whatever format is chosen, Blu-Ray or otherwise) as happened to DVD. DVD’s are now widely ripped and duplicated all over the Internet. There are people out there who would rather halt the development of HD-DVD technology than allow it to be released and cracked.
2.) Heh, heh... That “Mobile” keyword caught your eye, did it? No, it’s not a laptop. I bought a Mobile Athlon XP for my desktop PC for two reasons.
First, the Mobile processor has an unlocked multiplier. All other Athlon processors are locked, meaning the only way you can overclock is to change the FSB (front side bus) speed. I’ve had a lot of fun messing around with overclocking to see how fast I can run my processor at different FSB & multiplier settings.
Second, the Mobile processor has much lower power consumption than the standard Athlon XP. This allows for the use of a lower RPM HSF (heatsink/fan), making it a great processor for a “silent” system like mine. Alternatively, some people choose to use a powerful HSF and overclock like crazy. The Mobile has a reputation for successfully overclocking by 20% or more. With some experimentation, I’ve found that I can keep my processor sufficiently cool by running my HSF at just 1000 RPM.
If you’re curious about the numbers, my Mobile is rated at 45W. A standard Athlon XP is about 70W, an Athlon 64 is about 90W, and a Pentium 4 is about 80W (I read somewhere that a Prescott uses 110W... have to check up on that). AMD makes XP-M processors that consume only 25W, and the amazing Pentium-M uses just 7W-22W.

Wow... Got a little off-track there. Anyway, yes, I definitely have some ideas to run with for capturing the WMV. :-) And I would like to see the 160 MB capture you made.

darkflux Guest | Steve you crafty little devil you >,
i was startin' ta think you were crazy, not trying it on a desktop first i didn’t even know Mobile CPU’s could FIT in PC motherboards! shows how much i know. my PC has some settings in the BIOS to change FSB and other items i can’t remember offhand, but i dare not mess with them for my PC is alreadyplenty uneasy from being overloaded with hardware i’ve read quite abit about OC-ing, but ultimately decided to leave it be for now. however, that’s quite interesting info (watt ratings) you’ve gathered, an i doubt i could’ve found it even if i were to look! thanks
for the record i don’t care very much for ANYTHING that makes stuff harder to do (especially when computers were supposed to increase productivity!), and this includes the lousy DRM. all those free iTunes downloads from Pepsi didn’t go to waste, (heh heh). woah, now i’m getting off track...
sadly, DRM files cannot be edited in their headers (other than hex, maybe?, which i don’t know much of), not even the Tags can be changed... WinMedia Encoder 9 comes with a WM File Editor to do this for regular WMVs (check your Start Menu).
if you’re talking about the same Sessions@AOL videos i am, then maybe you CAN dL them... this has been tested at “channels.netscape.com/ns/music/videos/sessions.jsp”.
first of all, you’ll need NetTransport 2 (it’s free, google it). also you’ll need the MXID from the video. this can be attained by launching the video, pressing CTRL+N (new window), and View > Source, and search for “MXID” (without quotes). copy this number, and go to:
http://atlantisboy.hostrocket.com/aolstream.php
paste it, choose your type, and click “Fetch”. copy the URL and start up NetTransport 2. click “New” and paste the URL (if not already listed). download.
there are some “feeds” that NetTransport won’t fully download. for these i recommend WM Recorder or RM Recorder (google again).
there are tricks like this for ALL MVid sites, if you want them, just ask me : )
i don’t think i’ll have any trouble hosting the file temporarily. i have a REAL nice Web Host (500GB/mo. transfer with $0.49/GB over that). i’ll post the link to the file once it’s uploaded. oh, and that 2-5% frame drop was just an “uneducated” guess as to the actual drop; it could be more or less, the program i used said there were none. i just went by my experiences. still looks “good” though.

Sivlap Guest | How about outputting to a DVD recorder( the stand alone ones not the computer based DVD Writers as they are called). Most video cards have an S-Video out. Has anyone tried this??
I am about to pick up a DVD-Recorder tomorrow to try . I have a headache from racking my brain to try and come up with a work-around for the DRM this weekend. I have the right to play movies on the puter but I want to move the movies to a more flexible medium in case of a computer crash which I just recently had.
| | | 08 Dec 2005 08:18 am |
darkflux Guest | that might work Sivlap, provided you’ve got a powerful enough vid card to handle the monitor AND another output. in the case of Steve_NSV, however, the file he’s got is such hi-qual, that it takes alot of juice just pumping it to his monitor!
if you have the option, you also could play the file on one PC and capture it using another, but once again, it comes down to having the graphical prowess to do so. if you can get it to work without frame-loss (our goal), please let me know!
thanx,
df

bumblinin Guest | from the README file of FreeMe.exe which opens with notepad btw
“quote
INSTALLATION:
There’s just a single executable file “FreeMe.exe” to install. You
can copy it so that it’s in your executable PATH (for example, copy
to directory C:\WINDOWS\COMMAND), or you can put a shortcut to it on
your desktop — see below.
USAGE:
This is a command-line program, and the best way to run it is from
the command line. If it is installed, and the executable is in your
PATH, all you have to do is type “freeme x.wma” at a DOS prompt in
order to unprotect the file “x.wma”. There is a verbose flag that
you can invoke to have it print out all sorts of information as it
discovers it (your public/private key pairs, KID of the file you’re
unprotecting, content key, etc.). For example, typing “freeme -v
x.wma” unprotects the file as above, but in verbose mode. The
output file will be called “Freed-x.wma”, where “x.wma” is the
original filename.
One problem with this being a command line utility is that many
audio files have very long file names, so you’ll have to put the
filename in quotes in order for this to work, like so:
Prompt> freeme “Billy and the Boingers - The RIAA Stole My Soul.wma”
As an alternative, you can put a shortcut to the FreeMe.exe
executable on your desktop, and then can simply drag files from the
file explorer to FreeMe. However, there is one big problem with
this: the filename given to FreeMe is actually the short filename,
so if you did this with the file above, you’d end up with an output
file named something like “Freed-BILLYA~1.WMA” Unfortunately, I
don’t know how to fix this — maybe someone else out there does.
endquate”
it works just fine

drm cracker Guest | I didnt read all post so bear with me:
freeme only cracks .wma files. There is another set of tools that removes drm from .wmv files.
It comes in a easy and complicated version. The easy version only works with Windows Media Player 9 and some foreign .dll files. The complicated version works with WMP 9 and 10.
| | | 01 Jan 2006 05:30 pm |
menatekera Guest | The 2 tools is:
1. drmdbg
2. drm2wmv
Also work with Windows Media Player 10
Can undrm both drm protected .wma and .wmv
Also work with HDWMV DVD

Devilmasterex Guest | I have a question. how do you create a media file that requires a licences to play it. I have the media file already. All i want is to encrypt the file with a licneces.
Please E-mail me the responce at mastermichaelc@gmail.com

Sunny_mu Guest | I reinstal my operating system but now i cannot play the Audio file that i copy in my computer. Because those file has Windows Midia Player Security. So How can i Play those Musice.
PLZ HELP ME TO PLAY THIS.
| | | 29 Jul 2006 08:19 pm |
darkflux Guest | okay, in order:
Firas, you canNOT crack wmv. best you can do is screen capture, and you can only do that if the file will play in Media Player.
mantaray, YES, burning a DVD WOULD be easier, but alot of the people visiting this site may not be able to AFFORD such an option (heck, half of them can’t even spell a single sentence out [lol]), and what’s more, most of us just want to share the file with friends, or have a portable, e-mailable file, or be able to do what they want with the file [which, ironically, is the very thing licences were created to prevent ], etc., and burning and re-ripping a DVD will drop the quality as well.
Devilmasterex, this is more complex than one would think. forst, you need to sign with a company to host the licence, set up the licence with them, then open your media file with Window$ Media Encoder (it may be on your PC, check your Start Menu > Programs), and add the licence from the web address the company gave you. oh, and you can count on none of this being free. although, you never know...
Sunny_mu, you’re screwed. next time use mp3.
anybody else?
