cenalyzer FAQ

fixes and improvements in version 3.0:

* Scenalyzer can now read and write the odml-file format (AVI Type2)
* Scenalyzer now writes files with the exact same interleave as the source-files, this removes the 'scenalyzer slows down premiere' bug with canopus non-ref avis.
* push 'clipsheet' to see a nice clip-sheet. This sheet can be printed out, too.
* Scenalyzer now contains a simple optical-scene-finder
* the audio-track of ntsc-files is now written correctly
* ntsc-timecode is now correctly displayed as drop-frame 29.97 fps
* the stills of your video can be automatically written to .bmp files using the 'export bmp'-button.
* if you are only able to capture 2GB at once, then capture overlapping sequences into multiple files. Scenalyzer will automatically detect overlaps of any length and remove them frame-accurately if there is an overlap of at least one second.

Q: What does Scenalyzer do?
A: Scenalyzer splits .avi files containing dv-video into the individual scenes thus saving a lot of time when you prepare your DV-material for editing.

Q: Does Scenalyzer work with D8 cameras, too?
A: Yes, it works with both, DV and with D8 material. Whenever it says 'DV' here, it means 'D8', too.

Q: How much does Scenalyzer cost and where can I get it from?
A: Scenalyzer is freeware, you can download it from www.videox.net.

Q: What cards does Scenalyzer work with?
A: It should now work pretty much all dv-capture cards that use an .avi file format.

Q: Is Scenalyzer opendml-compatible?
A: Yes it is. If the source-files are odml-files, Scenalyzer will automatically generate odml-files.

Q: Is Scenalyzer NTSC/PAL compatible?
A: Yes it is.

Q: Scenalyzers datestamp-scan does not find any scenes in the material, whats wrong?
A: The datestamp is the time and date when the video was recorded. DV-Cameras store the datestamp information in the binary framedata. Scenalyzer identifies the individual scenes by looking for different datestamps in the material. If the video has not been recorded on a DV-Camera, it will not contain the datestamp-information, and Scenalyzer will not be able to identify individual scenes using the datestamp-scan -> use optical scan instead.

Q: I have copied analog video onto a dv-tape- or - I am using HI8 tapes in a D8 camera, why does Scenalyzer not find the individual scenes in this video using the datestamp-scan?
A: Because the datestamp-information is missing in the video files. See the question above.

Q: Can I use Scenalyzer with mpeg cards?
A: No. Scenalyzer only works with dv-video.

Q: Does Scenalyzer work with referenced .avi files as used by the Canopus-cards?
A: Yes, it does. Please note when using referenced .avi files: The video data is not stored in the .avi file but in a separate data file, e.g. capture.000. The .avi files contain the audio-data and the path of the capture.000 file. The capture.000 file must always stay on the same location (e.g. c:capture.000) where it was initially created by the capture-program. Scenalyzer creates new referenced .avi files which will still point to the original capture.000-file. Using referenced .avi files improves the speed of Scenalyzer (because the video-data does not have to be copied) but it has two disadvantages: deleting a referenced .avi file will not free up the disk space used by the video-data of this scene and you have to leave the capture.000-file on its original location.

Q: How can I set the disk/folder where the clips are written to?
A: Push the '...' button on the right of the edit control where you set the output-name.

Q: Why is that funny date-format 19991231 used?
A: This date-format allows correctly sorting the names of the clips by creation-date.

Q: Scenalyzer doesn't give me any preview-pictures or it crashes when I start scanning.
A: There is at least one card which has a codec that can not be used with scenalzer. Get a dv-codec from another capture card (e.g. search the internet for "dvcodec.zip"), install it and select it in the options-dialog. Scenalyzer will not use directshow-codecs.

If you like the program, tell your friends about it!

Personal notes:

If I'd known that everybody comes up with a different way of writing the word 'Scenalyzer', I had chosen a better name for this program, but now it's too late, so let's stick with 'Scenalyzer' :-)

While Video for Windows was somehow okay to use as an API, DirectShow turned out to be a reliable source of headache. Now Scenalyzer does not use directshow at all - IMHO life is just too short to waste time on badly documented com-interfaces.

I captured some HI8 tapes with the dvmaster, and with some video the optical scene detection finds all cuts while with other video it just finds junk. I hope optical detection works fine for your video, and if it doesn't - please don't ask me to improve it :-).

I'd like to hear from scenalyzer-users: just drop me a short note (including the type of your dv-card and your OS) in english or german to scenalyzer@blackbox.net, I hate spam and be assured that I don't give away any e-mail addresses.

L'un d'entre vous peut-il me dire où on peut trouver des informations concernant l'utilisation de SCENALYSER, car le site VIDEOX ou on le trouve est peut etre bavard, mais il est en allemand ! D'avance merci.
