Questo dovrebbe farlo:
IBM VideoAnnEx Annotation Tool (http://www.research.ibm.com/VideoAnnEx/)
IBM MPEG-7 Annotation Tool (http://www.alphaworks.ibm.com/tech/videoannex)
download (http://www6.software.ibm.com/sdfdl/1v2/regs2/awadmin/videoannex/Xa.2/Xb.NoLYpqLtnyxkNuJNUXaIxMj0CoGdjqO7IyUyZGk/Xc.videoannex/VideoAnnEx_v151.zip/Xd./Xf.Ltr.U1ay/Xg.3991236/Xi.AW-07Z/XY.regsrvs/XZ.auZ6SMjGxrOYkLKPn6kHM9rAQ_E/VideoAnnEx_v151.zip)

Quacuno sa indicarmi come sono codificati in XML questi documenti MPEG7?

Perchè ho 1 po' di confusione .... :stordita:

Forse ha questa forma:

<?xml version="1.0" encoding="iso-8859-1"?>

Il SW di prima pare aprire solo file MPG e MPEG.
Ma 1 file MP4 non appartiene a quella categoria?

Che tipo di CoDec deve avere 1 file MPG o MPEG x essere aperto?

Quando lo apro mi fa così:

, e poi mi crea 1 file così:

Pare che MPEG-7 e MPEG-4 lavorino molto bene assieme, quindi 3D inerente può essere:
MPG e MPEG come devono essere formati? (http://www.hwupgrade.it/forum/showthread.php?t=1521837)
