Regarding Adobe premiere elements 12, you can import 1080p 50/60p ACVHD, but can you EXPORT the final movie in the same 1080p 50/60p?
I´ve read a lot now. "Adobe Premiere Pro 11" cannot do it. Nor can "AVS Video editor", "Avid Media composer 7" or any other software I have read about (except Sony Vega Pro)
So, out of 30 video edit software programs - there may exist one or two which does not affect the final movie.
Premier Elements 10, 11 and 12 will output or export to 1920x1080 50/60p. (Publish+Share > Computer > AVCHD > MP4 1920x1080 30 > Advanced > Change the frame rate > Save as personal Preset ).
There is a reason that few of the 30 NLEs do what you want. It is because very few videographers what to publish their work without improving it in post processing. The same is true for photography. We capture light data, even on film, and work to "develop" the potential of the captured light data.
The concept of output being the exact same as input, frame by frame, is usually called "lossless editing". No offence to those that want to practice it, but it is a limiting goal most suited to people that want to share camera tests and camera manufacturers that want you to have a simple "lossless" option.
To be lossless the software has to be so limited in functionality it becomes almost useless for anything remotely creative.
Panasonic's "lossless" capable software is HDWriter. It does work for lossless editing if you follow its precise rules. Sony's solution was called PMB (Picture Motion Browser) and is now called PMH (PlayMemories Home). Sony has precise rules too. I don't know what Canon or the others provide. I've used Panasonic's and Sony's software on an ordinary laptop with no problem, as long as I follow the precise workflow rules.
The single 3rd Party NLE in the low priced category that claims to do lossless editing is called "TMPGEnc MPEG Smart Renderer 4". If not used it, but some extol its virtues.
I've read that both Sony and Adobe professional (read expensive) software will do limited smart rendering depending on the user accepting precise conditions.
If you want to make HDWriter work for your "cut and stitch" lossless editing, I may be able to help you. But, I need to know if you've read the manual and how you are using it, step by step.
