[Tool] WMV Aspect Ratio Changer 1.0 released

crypto · 6th October 2006, 21:21

I have made a tool to change the aspect ratio of WMV files without reencoding. It writes the AspectX and AspectY properties in the meta data header as discussed here and here

Enjoy!

Current version is 1.0, get it here

Does it works with VC-1 streams or it is the same tool like MetadataEdit ?

AspectRatioX and AspectRatioY are ASF attributes. Crypto's tool will only work on ASF containers. It doesn't touch the VC-1 bitstream.

Many thanks for this. While MetadataEdit.exe works well for certain attributes, I've had no luck trying to add (or modify) AspectRatioX or AspectRatioY. Just kept getting error messages.
This tool, however, works very well for me, so thanks again.

This is very useful since last I checked Nic's Encoder couldn't set the PAR. Thanks.

Errrrrm.... Not to sound too ungrateful.

But is there a chance future builds could include support for changing the AR signalling values of WMV streams placed within the .AVI container?

Cheers

Of course I can't speak for Crypto, but what you're asking for is a completely different ballgame. With any container other than ASF, you'd have to change the AR signaling in the VC-1 bitstream. You couldn't just add "AspectRatioX" to the the AVI RIFF header because the AVI source filter wouldn't have a clue what to do with it.

crypto · 7th October 2006, 23:30

Exactly like zambelli says, that's completely different.

I am not even sure what needs to be done. To me it looks like Data Unit Extensions are required on every sample, thus requiring the whole stream to be rewritten.

tried it-it sets PAR not DAR

Only PAR is supported in WMV.

Okay... thanks for the confirmation

Unfortunately this doesn't actually work on a WMV file, yes it changes the metadata object [can check in asf view] , but the display is exactly the same PAR as it was previously.
There must be another parameter that is changeable surely?

crypto · 24th November 2006, 17:42

The player has of course to honor the meta data for this to work. The XBox360 dashboard player does not. It is a confirmed bug.

daniel.aam · 24th November 2006, 17:45

I was referring to WMP.

crypto · 24th November 2006, 17:54

With WMP it works 100%. What do the file properties in WMP say?

jaswah · 4th February 2007, 23:29

hey
i just wanted to say a massive thanks to crypto for this.... it's allowed me to encode heaps of wmv's using avs files in apps other than WME, and i'm very happy!
so thanks again for the generous offering!

Sorry to raise this thread from the dead but I have been investigating the PAR metadata values AspectRatioX and AspectRatioY in the WMV container. I have had a need to change these values on a hundred or so files.

It is interesting to me that MS sdk sample MetadataEdit.exe does not succeed in modifying these attributes. Did it work once with WM7/9 and was disabled because of WMV script secuirty holes?

Well the wmvarchanger from crypto does work but only for single streams. On mulitbitrate streams only the first stream is modified.

I am still left with a task ahead. To modify the sdk sample app to work properly and modify the metadata values. Anyone pursued this? Or to hexedit the streams - this is the probably the way is done by wmvarchanger - I suppose this way will work without pain but what will be learned

thanks dude....works like a charm
