Avi (DV) Data Analyzer

[Fizick]

Do you know about russian AVI data analyzer (beta version)?

The Freeware AVI Analyzer is the one and only known program in the world (at least in 2005) with ability to see all available metadata from your AVI digital video (DV format, not MPEG2/4 etc) file. It sounds very simple, but the fact is that nobody did this program before. There are many programs that retreive the date and time, but there is no program that can show you the exposition parameters of scene. This program actually reads the EXIF information of your video. The program retrieves recording time, tape time stamp and exposition data (like shutter speed , gain etc.) from AVI-stream without changing it. Saves the still pictures as bitmaps with optional printing the retrieved data to this bitmap. You can also create new AVI-file with all auxiliary information printed in to the stream and in addition capture video from your camcorder and print it back to the tape.

That is pretty cool, thanks!

Now I can see how much gain has been used by my Sony PC100E (a camcorder with an AGC function that can't be turned off)
It also reports the camcorders weird use of the automatic shutter control - which of course also can't be turned off...
I didn't know that this camcorder would suddenly set the shutter to 1/75 or 1/100 to reduce light while at the same time using 12dB gain. Damn automatic crap ;)

Thanks again for the program!

After loading the file, it only showed the first video frame.
It was all black after that, although it was showing the analyzed data all the while.

However, when I hit the play button and then grab and move the app.'s window the video appears. Don't know if that is a NTSC problem or not.

Not complaining at all, after all it is free.:)

For me it suddenly won't work anymore at all...

It does the same as you described, but it won't show data anymore...
I think I'm going to re-"install" it and see if it helps...

but there is no program that can show you the exposition parameters of scene.

That's not really true!

Our DV decoder does exactly that...see the attached snapshot. It also displays other useful information.

@Fizick:
1)There is no EXIF in AVI.
2) Use ABCAVI Tag and you get every information available in AVIs, inclusive RIFF info/struc Viewer. http://abcavi.tk/

Fizick is refering to the camera settings metadata that is stored in the DV data (which, in turn, is wrapped in an AVI).

The DV data stores a wealth of information about the camera settings.

A RIFF dumper won't do give you that information unless it understands the DV metadata, too.

EDIT - Just tried abcAVI. It's a nicely written program, lots of features etc. However, it only works on Video for Windows-compatible AVIs (according to the program!) I captured a DV video to Type 1 DV-AVI and it refused to work with it.

it is not my program, and not my description. :)
