Not sure the console command works with audio.
The open poster Dan said that he wanted to take advantage of the camera audio recorded for sync.Fred.

Hi,
Avid will compensate by default on import/ama to match your project.If you want slow-mo you’d need to promote the motion adapter applied to effects otherwise your sequence would look as if it was 24p.
You can Also import the clips in
A 60 Project, them import the bin
Of those in a 24 project.Audio: what about bwf ?

Dave,
I do use too AVCHD cameras. My point was not at all about the economical side; we all do our best with the budget we have.
And within each budget, there are more or less limitations, and-or
more or less complications involved.
AVCHD has clear advantages, but also known “downsides” and we can always take decisions (that not necesarly involve investment) to minimize its “weakness” within the workflow.
(IMO it’s neither weak nor has downsides in the sense that this is an adquisition codec that is concived to give an optimum relation compression-performance, low-cost storage etc… and therefore meets the requirements it was engineered for).
Avid has a great range of robust codecs flavours for tasks AVCHD has not been idealy made for.Also, not all AVCHD implementations are similar (I’m thinking of the AF100 for ex that is more robust than the GH2 for CC).
To resume, I do use AVCHD codecs, but I transcode them after review, when time isn’t a concern.
PS: talking about AVCHD, today, completly by accident I falled on some GH2 footage that surprised me a lot because it was more solid in CC that what I had seen before and made a little enquiry. It was a hack all INTRA and GOP1 at 150 Mb/s. Digging a bit into the hack saga, it seems that GOP1 has very benefic effects on robustness because each frame is fully rendered avoiding too much compression artifacts in the frames that are grouped (GOP3,6 etc…). I tried one on Scandisk Extreme 30MB/s and no freeze, perfectly stable in 24 and 25p. I think it’s called something like “Cluster Moon V5”.
But in the end, GOP1 goes “against” the philosophy of AVCHD, and intra needs at least 100Mb/s to render correctly. So it’s like this hack is in a way saying to the camera: “you’re not AVCHD any longuer”, but it works and totally free.Cheers.

About the .MTS container, ( with avchd codec for ex)
Imo it’s a very good consumer adquisition codec but That’s it.
I know that a lot of “info” is circulating over the https://www that people are grading happily with it, but it’s a very bad intermediate codec for big volume because it obliges to complex calculations, wich unnecesary stress the nle, and it’s a very weak codec for image manipulation, cc included.
I’ve been doing testing using Nuke with original .mts and the same file converted to tiff and qt jpeg2000 and it’s not the same story at all.
Without talking of the madness file structure.
The convertion of course doesn’t ad any datas but it stops the bleeding.
The fact that Avid is not friendly with it is not Imo a weakness but a reminder that it’s
Probably better to transcode.
I’d use AMA only for mts selection and transcode the elected clips, better at the very roots
(not even edit with) so you’re sure
To edit stable in 36 and conform to
A robust codec but not the mts.Fred.

Thanks Shane.

Talking about that,
Not sure if it’s also possible to export QTref with longGOP medias either.
I beleive it isn’t or it wasn’t. Does someone confirms that? or has it changed?

That’s exactly this camera I was talking about.
Yes, much better than a GH2.
If you can wait, I’d save the GH2 money and buy this one.

Yeah,
What I find with Avid is that if it’s not practised regularly, it’s easier to forget than other NLEs.
Avid is IMO the most robust editor but the counterpart is that it requires regular practise and training.The BMC will not be available easily. I think the camera will have so much success that I doubt BM will be able to supply the world demand.
A GH2 still is a good choice, not as good as the BlackMagic, but at least very cheap and immediatly available.
If you edit long feature-docs, I personaly recommend to transcode to DNxHD and not edit native.
Just reconform to your source files when edit is done.My personal Avid workflow with AVCHD would be (but it’s very personal and others will have different opinions):
1)- I would import the AVCHD footage in DNxHD 444 RGB (your Project needs to be in RGB mode and not in video, you find that in the colorspace of your Project settings). No AMA.
2)- I would transcode all the 444 material to DNxHD 36, once done, put all the DNxHD 36 into another bin, switch to video colorspace and edit with those.
3)- When the edit is finished, relink the sequence to the 444 material.
4)- Color correct in RGB mode within the editor with the available color tools.
5) Master in JPEG2000
But this isn’t the only posible workflow, there are many. What’s sure is that I wouldn’t edit nor doing any manipulation with AVCHD material, regardless of the Workstation power.

No stupid questions, you are just starting with nle and digital video and we all went through that.
About the gh2, wait before decision. Go to the blackmagic website and look for this new camera, less than 1000 euros, RAW dng, micro 4/3 mount. It’s going to give you a film look and no banding issue. A much better option than the gh2: https://www.blackmagicdesign.com/uk/products/blackmagicpocketcinemacamera/
But it will not be available until july and I doubt BMC will be able to feed the demand for awhile.On the avid, there are many video tutorials, starting from the basics. That’s the best way. In the cow, just youtube the Creative Cow user and they are all here.
Or directly from this site: https://library.creativecow.net/tutorials/avideditingAma is a link or Access to your material instead of a
Transcode. So you can edit natively without the need of transcoding to avid media.It’s good when you want to edit short docs, musical clips, etc…in my opinion not good for feature film, Long documentaries etc…
Best luck

Hi,
AMA doesn’t work reliably enough IMO with GH2 AVcHD. The plug-in for some reason with the Panas files gives me issues. I ignore why.
Simply instead of using AMA, just import the files directly to the DNxHD flavour of your choice. Simple. (and go-out for coffee, shopping, driving, while the transcode occurs… )
Make sure your Project has the same frame rate.
Make sure you have intalled the AVcHD plug-in AMA. (even if you won’t AMA the files)
And you’re good to go.
Fred.
