If iphone can record avchd "like" video and do cuts only NLE right in the phone, what you're saying is totally doable in my mind.

Daniel Symmes November 12th, 2009 09:49 PM

I had a good laugh at that. I was going to SAY that.

Why not?????

I was on a shoot at the weekend and the client needed me to record in 100mbs 1080p 30fps to match the Canon 5d MkII with the Iconix I was using.

They were editing in FCP and so needed .MOV files.


Hi Stuart,
Shoot p29'98 and Conform to p30 in CinemaTools. Just a mouse click, no rendering.
- The Canon only records at p30.
- FC can edit p24.

Any Quicktime in any Flavor

We issue that warning to prevent one for recording files that can not be edited.

Typically (almost always) Quicktime (".MOV") files are edited on Final Cut Pro.

Final Cut Pro does not support "True" frame rates.

While Final Cut Pro will handle 23.976 (23.98) frame per second video, it will not handle "true" 24 frames per second video.

The same applies to true 30p.

We allow True 24p and True 30p to be created in MXF as Avid and others do edit these "True" frame rates.

....HI Dan: Just so you know, Avid on the PC or MAC can ingest any format Quicktime file at any frame rate and edit them in that native frame rate. Quicktime is the heart of Avid Media Composer. When the QT file is ingested or imported, then it is wrapped in an MXF container file, but you don't have to be pre-wrapped, if you will, to get it in there, or have it work. When you do an export to quicktime from AMC at what they call 1:1 resolution, then Avid strips off the MXF wrapper and it simply copies over the file it was editing with (No Transcode takes place here). I hope this helps ?

Dear Mark,

Thank you for your informative post.

Will Avid handle True 24p while using a Sony XDCam 50 Mbps 4:2:2 @ HL CBR file?

You're Most Welcome Dan
Hi Dan:
I've upgraded to Avid Media Composer 4.0.3 running on an Avid Certified PC System, so if you require any specific file type testing, then I would be happy to assist you and the folks at CD with beta testor results. I'm also going to take some time and have a close look @ Long GOP 100 Mbps MXF files again. I suspect something. What if I shot Long GOP 100 Mbps, but this time as a simple Quicktime .mov file and imported *that* into AMC ? Dan & Mike & Tommy, I don't know if you've been informed, but that should work for several reasons. If it doesn't then I also suspect a possible work around. I will get back to you and post quantative specific results.


Dan Keaton November 13th, 2009 01:23 PM

Dear Mark,

We would greatly appreciate you testing, in Avid 4.0.3, the following:

Our MXF 100 Mbps 4:2:2 Long-GOP.

Our Mov 100 Mbps 4:2:2 Long-GOP.

If these work, then you could test higher bit rates.

The MXF 100 Mbps 4:2:2 Long-GOP is the most important one for us at this time.

I Forgot To Answer Your First Question

...Hi Dan: I just realized I forgot to answer your question directly. So sorry about that :-) Yes. AMC 4.0.3 handles all formats *Natively* Therefore, the answer should be "Yes," but I will test to find out. To be absolutely accurate in my tests for you, could you provide a download link where I can download all the test files for your necessary codecs and data rates ? Perhaps these could be special files made by your engineering department, which you absolutely and positively know are at their rates specific to our tests. I can certainly go shoot them myself, of course, but maybe you guys should provide the files specific to your needs as part of the control measures for this test. I only want to provide some sort of definitive and accurate feedback here.


EDIT: I forgot you have some test files at the LOng GOP 100 Mbps rates with different fps on your website, so I'll start with those.

Dan Keaton November 13th, 2009 07:13 PM

Dear Mark,

Here are some test files that Tommy posted earlier.

These files are in our latest format, "Sony Optical Disk Format"


Mark Job November 13th, 2009 09:11 PM

Testing, Testing, Testing
Hi Dan:
OK. But these are not Long GOP 100 Mbps MXF files. This is another format. I have just completed a testing of the Long GOP 100 Mbps MXF format, and I will post the the results shortly. I want to check out a possible work around proceedure first. I will test Tommy's files now and post the results shortly.
