Just to update: I finally manage to update a custom mpeg4 profile with a new resolution.
The strange is I didn't understand why it didn't work before.
Need to say the whole process it's a bit complex. During this resolution change I also test the substitution of a new audio to a mkv video encoded with AC3 audio. It need: conversion of mkv to AAC audio (using external tool), conversion of new audio also to AAC (using another external tool), split and substitution with new audio, creation of new profile, creation of new MPEG4 file with AAC audio.
Using a freeware I can simply load the video, add a new audio, produce the new mkv video with aac audio.
My suggestion for Cyberlink: add support for AC3 at least for import, give a better interface for resolution change.
About all the other editing features I'm really satisfied, it's fast powerful and easy to use, definitely a prosumer video editing tool, not oriented to simple tasks such as video format conversion.
