MSU Screen Capture Lossless Codec 1.0 released!
This codec is intended for lossless compression of video taken from computer screen. It may be used for making software presentations, video lessons and tutorials, recording video from games etc.
Main features:
* Now many times better than Huffyuv on such files!
* We clame best compression rates (please check us!)
We've compared results of proposed algorithm with other available codecs results.
Comparison was made on several sequencies captured in DOSBox emulator from several games (UFO, Jazz Jackrabbit, Test Drive 3, Ultima 6 and Lemmings). All these games except Lemmings ran in 256 colors mode, Lemmings ran in 16 colors mode.Codecpage: video/ls-c..._codec_en.html

Enjoy!

yes it does
Nice!
MSU codec beat even Techsmith screen capture codec
I made test on small screen recording in 24 fps (Recording lenght 0:49.66 min, grabbed in techsmith camtasia with techsmith codec, with no audio, resolution 1024x768 in 24bit color):Code: MSU Screen Capture Lossless Codec 1.0.avi 2,13 MB 2 186 KB TechSmith Screen Capture Codec 2.06.avi 3,06 MB 3 138 KB FM Screen Capture Codec 1.0.avi 5,94 MB 6 090 KB CAMstudio Lossless Codec 1.0.avi 7,53 MB 7 714 KB Lagarith 1.3.8.avi 80,7 MB 82 712 KB CorePNG 0.8.2.avi 85,3 MB 87 358 KB Alparysoft lossless codec 2.0.avi 107 MB 110 584 KB uncompressed.avi 2,62 GB 2 748 582 KB
settings were set for max compression for every codec (null frames on for lagarith) and full lossless (no color conversion).
Also, MSU codec seemed to be fastest in bunch!
wery nice indeed

MSU codec in default settings.):
MSU Screen Capture Lossless Codec 1.0 = 2,186 KB
TechSmith Screen Capture Codec 2.06= 3,138 KB
wery nice indeed
Our research is in maximum compression.
Thanks for independent comparison!
tested on first 40 seconds of the movie stuart little. this includes the columbia(movie studio) opening and a bit of the opening credits.
resized to 352x288 at 25fps.
MSU
----
size = 115mb (same with fade detection turned off)
time = 2 minute (1 minute 57 seconds with fade turned off)
Lagarith RGB mode
------------------
size = 95mb
time = 44 seconds
Lagarith yuy2 mode(both input and in codec settings)
-------------------
size = 56.7mb
time = 36 seconds
null frames was disabled for both Lagarith encodes.
i also got a completely black picture for MSU playback. turning output to overlay in MPC i got what appeared to be a couple of frames but still seemed to get stuck on a frame and not show the ones after it.
i will try some different clips tomorrow and see what happens then.

Maybe this was not so clear, but quot;MSU Screen Capture Lossless codecquot; is designed for lossless compression of specific video taken from computer screen. (it's main competitors - TechSmith Screen Capture Codec and FM Screen Capture Codec). It overtake Lagarith on such video in several times.
Please use quot;MSU Lossless Video Codecquot; for lossless compression of movies: video/ls-codec/index_en.htmlOriginally Posted by dragongodzi will try some different clips tomorrow and see what happens then.
Ok! Please take into account - sequences with 265 or 16 colors with dithering are welcome! On such sequences (in program tutorials or old game examples) common codecs like XviD work not so good. Such area (not so big, but not so small) - is area of Screen Capture Codecs. Also please use other screen capture codecs or MSU Lossless Codec in your comparison if possible.

Wow! It's not so typical for us!
We did not make our own time measurements (speed is next step after bugfixing and public release), but your results sounds encouraging!
How do I get it to show up in CamStudio?...its not in the codec list
And is it possible to use this with fraps?

Fraps uses it's own codec but it would be nice to see a comparison between this codec and Fraps.
fraps codec is absolutely horrible
if recorded at full resolution something as simple as a four minute video can take 4 GB
if recorded at half resolution a video would take up 10 minutes--gt;1.5 GB
A comparison of system resources and compression ratio based on the same source footage. I could easily say Fraps will turn 4min of captured video into 2.4gigs instead of your 4gigs.
I can't see it in CamStudio's codecs list neither in DemoStudio's list!
Too bad for me!
ok a new test of a captured screen while i opened some windows, looked at a text file etc etc etc. only 30 second clip(720x576 section of my screen) because capturing it uncompressed was huge of course.
lagarith
-------
size = 30.6mb
time = 28seconds
MSU capture codec
------------------
size = 6.13mb
time = 35 seconds
MSU lossless video codec
------------------------
size = 6.32mb
time = 3 minutes 5 seconds
thats set at balanced, set to max compression estimated time was over 1 hour.
heres a funny result though. i turned it to maximise speed and it resulted in a size of 6.22mb and time was 2 minutes 26 seconds. so smaller and faster.
so yes this codec appears to compress things like screen captures very good. however of note is the speed. that it was not compressing real time with my athlonxp 2400+ while lagarith easily did. this wouldnt be a problem if capturing at a lower rate such as 15fps of course but if i wanted to capture realtime i suspect i would end up with some dropped frames using this codec. if you can speed it up a bit, even as an optional compression loss(so faster but doesnt compress quite aswell option), then this would be a very good codec for any capture speed.
DmitriyV2 - a couple of tips about critiquing peoples posts.
Please take into account - sequences with 265 or 16 colors with dithering are welcome!
please do not try and tell people they can not test on any other type of footage to see what the codec does with it. yes you said what type of footage this was for but if i want to see how it handles movie footage aswell and report that then its also a valid test and possibly important information for other users.
Also please use other screen capture codecs or MSU Lossless Codec in your comparison if possible.
please do not try and tell me what codecs i should or should not test against. the fact is Lagarith is also a lossless codec and infact you used not only it but corepng, huffyuv etc in your own tests. if you use and compare against a codec then others have every right to make their own comparisons with the same codecs, or even other lossless codecs you may not have.
well screen capturing usually is done at few fps imho
well screen capturing usually is done at few fps imho
to which i already said this would not then be a problem. however screen captures are not always done at low rates. an option or ability to handle such cases would not be a bad thing would it ?
This sounds very interesting, so yeah please make it work in CamStudio... (I also tried)

We found a problem root. It will work if monitor will be in RGB24 mode! Other modes will be patched in next version.
dragongodz! Thanks for comparison!
Other screen capture codecs is our real competitors (see results of GmorG McRoth), whats why comparisons with them are interesting for us.
Also: This two codecs has completly different compression methods inside. But in future we planning to merge this two codecs to one codec with sophisticated data type recognition. Hope we fulfil this plans after set of current patches and fixes (it's easy technically to test and fix separate codec). Inspirit support is welcome! |
