[Morgan Reese] “Can fcpx handle the high mbit files”
FCPX has no problem with bit-rates, in any case would be a system issue (HDs) to manage high data rate stuff. Whatever the stuff you bring to a NLE, will be managed as Uncompressed and processed some times in higher bit depth, (FCPX manage color in 32b) what means higher data rate than the original stuff.

The hacked GH2 stuff is some times close to Prores HQ, so if your system can edit prores HQ you shouldn’t have problem.

[Morgan Reese] “With or without the hack is there any downside to using clapwrap to get the files to quicktime?…or is it better to allow fcpx to make an archive and then convert to prorez?”
If I’m not wrong, you can import that stuff directly to FCPX. No reason to use ClipWrap.

[Morgan Reese] “can any gh2 shooters comment of their settings for video. I’m also very impressed by the driftwood avc-intra hack and will probably run it if the card can handle it. Can fcpx handle the high mbit files?”

I’ve been editing GH2 footage on FCPX for about 5 months now. I haven’t used any high bitrate footage because the native 25mb 1080p looks darn good.

Like Rafael said, there is no reason to use Clipwrap. I just let X rewrap the files. I don’t bother with Prores.

[Morgan Reese] “My laptop is supported for fcpx but it’s barely fast enough and I’m sure these hight bit rate files will be a struggle.”

It’s not the bitrate you need to worry about, it’s the compression. I’m using a 2011 Macbook Pro with 16GB of RAM and that is working well for me. I’m also using an external eSATA media drive. Grab the trial version of X and do some testing to see how it runs on your machine.

thanks Rafael and Jason. I shot some quick stuff with the driftwood v7 hack which I thought was @150mbit but the files are coming in @80mbit and they do seem sharper then the 24mbit. Btw the hack was easy from these directions https://is.gd/auB26Z and you can switch back easily.

So far my 2010 macbook pro is playing them fine in this quick test even from the internal drive and not my usual fw800.

A few more questions: I can’t find any inspector info on bitrate within fcpx…the only way I could see the bit rate was to use clip wrap and then use quicktime inspector…is there another way?

I also thought h.264 was not good for editing especially if you will be compositing/grading…I thought prorez is better for that??? You just fly with a straight import?

I’m also very interested in and gh2 settings for video but I will post that in the dslr forum.

thank you

The mayor problem is not on the codecs but in the NLEs or applications to manage them.
Is to the developers to give them the tools to manage them.
Few years ago was almost impossible to work with any kind of MPEG in a Mac and now is not any more like that.
FCPX has been fitted to work with H264 without transcoding so I don’t think you will get much advantages on transcoding to prores.

PS: I’m waiting for the patch for the new GH2 firmware to hack my camera, but I don’t think I’ll go to the Driftwood. To high data rate for 420 I think is unnecessary.

Hi guys,

I have a quick question in regards to editing the GH2 stuff.
I see that FCP 7 can transcode directly via log and transfer, and it sets the sequence compressor to apple pro res HQ.

I have a crappy dual core 2.4ghz at home, which can edit pro res lt fine. So what i’m wondering, is whats the best way to do an offlline online edit, by converting the avcs intra to pro res lt, and then reconnecting it to a pro res HQ version.

As far as I was aware the camera cant put out 10bit, so I dont see the point of using HQ, just plain 422, should do the trick for bit rate, with the lower data rate of driftwoods hack (44Mbit).

So what is a good process here.

I havent bought the camera yet, but i’m looking into it real soon, just trying to make sure life wont be too complicated due to my crappy computer 🙂

Can apple compressor convert avcs intra to apple pro res?
