For my blog site I need to convert many video files on daily basis. It is fair to say I used quite a lot of converter both os x and windows.

ATM I did not find any converter that does all my jobs nicely. Ivideo Converter doesnt either.
But for most of my converting tasks it is clearly better then any other available.
I keep reading comparisons with visualhub and in some extent it is fair to compare both. But be honest, the interface of visualhub is not very user friendly.

Note: The new preview feature added recently is highly usable !

My conclusion:
Is it perfect? No ... but very close to be perfect and I am sure it will get perfect in time.
It is surely a masterpiece in the works
