Hi there,

I have recently moved from Windows (where I could natively edit AVCHD) to a Mac, where I have some difficulties gettting a decent output from iMovie/FCE. I saw a link to RevolverHD that could solve my problems, but after reading about it here, I still don't get it. :) Hope you can help me out..

When I import movies from my camera with either iMovie/FCE (or VoltaicHD and then into iMovie/FCE), it gets transcoded to AIC. I'm guessing and hoping that this process maintains the quality of the movie and doesn't reencode it with a loss of quality?

And now to my main concern; when I export it from iMovie/FCE, there are a loss of quality due to the encoding - regardless if I then use RevolverHD to make it into a AVCHD file again? Is this correct, or am I able to take a "raw" output file from iMovie/FCE and the make it into AVCHD with RevolverHD?

Best regards,
Frank

Managing AVCHD

Hi Frank,

when you convert to AIC there is no quality loss (according to Apple). This does appear to be the case in our testing also.

You then edit the full HD content to produce a final project.

From here you can export a full HD movie, but it will be a QuickTime movie containing H.264 video, encoded at Medium Profile. AVCHD and Blu-ray require High Profile H.264, which QuickTime does not produce. This means that you cannot get from your iMovie or FCE project to AVCHD without another conversion into true AVCHD format.

RevolverHD does not support the creation of AVCHD movies from QuickTime.

If you are looking to playback a completed iMovie or FCE movie on a high definition TV, the simplest option is to export to AppleTV format (720p) which is still HD, just not full HD. You will then need a Mac Mini or AppleTV to play that movie via HDMI into your HD TV. Thats what we do at ShedWorx.

With the next version of Quicktime to be released under Snow Leopard, we may see Apple support the exporting of projects to Blu-ray movie format (AVCHD and Blu-ray are the same when it comes to video).

In the mean time we are working on a very simple native AVCHD editor (just the ability to trim clips and create a new single movie) that will be available under VoltaicHD and FlamingoHD.

Thank you justin Markos Web &

Hi Gonzalo,

the process outlined above will work just fine with Final Cut Pro. We are just doing basic editing, then exporting the 1920x1080 project/sequence out to AppleTV.

Hi Justin,

Thanks for the excellent answers - really appreciate it.

When you get that version ready with the simple AVCHD editor, I'll definitely buy a copy.
If you run out of development ideas later, you could consider making an addon/another products that ties clips together with a couple of simple effects (fx. fade out/in). My guess is that with a native AVCHD editor (and maybe coupled with a simple effects creator) you could get a lot of those customers that don't want to spend a huge amount of money on full blown video editors, when they really don't need it.

Best regards,
Frank

AVCHD editing

Thanks Frank,

once we get basic trimming into FlamingoHD we will investigate simple transitions and titles. It will all depend on how much interest there is in native AVCHD editing. We're guessing that there is quite a bit as it does make the whole editing process so much easier.
