Hello, again,

I have a student who is still unable to export her Korsakow project. She is using the updated of 5.0.4 for PC (from Apr 18, 2010) and I have made sure all her media files are compatible (by making a test project using her exact media files, which I've thown up at: http://coolstudios.com/110/man…..llj/test/).

She has tried to create her K-Film on three different PCs, all with latest Flash and QuickTime versions.

(1) HP pavillion laptop, running Windows Vista

(2) Toshiba laptop, running Windows XP

(3) Fujitsu laptop, running Windows Vista

Here are screen shots of the error messages she's getting:

Any advice would be much appreciated!

Hi,

Another user has recently reported a simiar problem. I believe this issue is caused by a specific type of video on windows and we are working to resolve it. If you could send me a (small, 5 seconds will do) sample of one of the videos that causes this it would greatly help my efforts in fixing it.

In the meantime, if you could tell me the settings you used in preparing the video I might be able to tell you how to tweak it slightly so as to avoid this issue.

Thanks, Dave, my student says:

"I've been dutifully using the exported movies you gave me on the CD. I've been trying to export the videos, but the ffmpeg program is still shutting everything down."

I have posted the clips she is using–that I processed (on MacG5/OS 10.5.8) and gave her on CD at: http://coolstudios.com/110/man…..ted_clips/

Here are links to screen shots of settings I used

And below my instructions to student on settings to use.

Hope this gives you an idea on how to proceed.
cheers and thanks, Jenny//

>>> Quicktime Pro:
>>> – under FILE menu, choose EXPORT (not "export for web")
>>> – In dialog box, set "Export" to "Movie to QuickTime"
>>> – Click the "Options" box, then click "Settings"
>>> – Make sure the setting are set to:
>>> Compression type = H.264  (I know some people said they used MPEG-4
>>> video and it worked, but the Korsakow manual says H.264 and this worked for
>>> the test I made)
>>>
>>> Framerate = Current
>>>
>>> Key Frames and Data Rate should be set to AUTOMATIC
>>>
>>> Quality: up to you, but larger files can be an issue over the web
>>>
>>> Encoding: Best-quality
>>> – Then click OK
>>> – This will take you back to first menu, where you can change the
>>> dimensions (size) of exported movie and apply filters (like
>>> sharpening).

Hi,

Thanks for your help on this. I believe there may be an issue with H264 video on windows at the moment. That is, with exporting video already in H264 in some cases fails. Can you try preparing your video using another codec (MPEG-4, for example) and letting me know?

Thanks

Hi Dave,

yes, my student could export and view successfully on Windows Vista when she used video clips prepared with MPEG-4 compression. I posted the test she sent:

http://coolstudios.com/110/man…..index.html

Also, I had my students watch all peers' films and submit bug reports along with their system/browser info. I'd be happy to compile those and send along, if you think it would be useful.

Hi Jenny,

We've been working on a fix the problem you reported. After some internal testing it seems to work, but we would greatly appreciate it if you (or your student) could take a moment to try this release out and let us know if it fixes the problem.

We would also be very happy to recieve your report,  and I would like to thank you for taking the time to compile this information.

The candidate release is available at

Windows: http://korsakow.net/releases/k…..-win32.zip

Mac: http://korsakow.net/releases/k…..12-osx.zip

Here is an idea of the changes in this update to 5.0.4

  • Can press Command+Delete to delete resources (this should be familiar to Mac users. Windows users can use CTRL+backspace, though it is not a standard shortcut on Windows)
  • Some issues with subtitles have been addressed.
  • Fixed a problem where exporting to an external drive wouldn't work
  • Fixed a problem where exporting h264 encoded media on Windows wouldn't work
  • Updated h264 export quality
    • H264 Low is now 400k/s (roughly the same as previously)
    • H264 Medium is now 700k/s (much higher than previously)
    • H264 High is now 1700k/s (much much higher than previously)
    •  
    • These settings are hopefully now similar to youtube's 360,480,720p settings.

Of course anyone reading this is welcome to try out the prerelease (and let us know your results), but I would advise not to replace your current version with this and to back up any projects you test using this version as it is still just a release candidate.

Dave
