Mixing DVCproHD files with H.264 files - disaster?
on Jan 3, 2011 at 4:28:04 pm

Hi,
We are eding a project that is shoot in the DVCpro hd format(1920X1080) 25 fps. We have used a Canon 7d as a second camera H.264 (1920x 1080)25 fps. Is there a good way of mixing this formats in fcp, or should we convert the H.264 images to DVC pro HD?

Project timeline is set to DVCproHD.

Best regards: Paul

Raul

In FC you can mix every kind of supported formats.
If you have a look to the list of those supported formats (FC's manual), you will see that H264 is not among them.
Convert your H264 to Prores, and edit everything on a Prores time-line.
Keep your sequence DVCProHD only if you need to deliver on that format.
Cheers,

Absolutely. H.264 is in no way, shape or form an acceptable editing codec in FCP. To do the job properly, you should watch this:

Hi,
Thanks for the advice. The problem is that FCP7 wants to render the H.264 files for every change we make, since the sequence format is set to DVCproHD. Perhaps this could be solved by using some of the prorez codecs as the editing format?

we have used the calibrated mxf import plugin(http://www.calibratedsoftware.com/MXFImport_Mac.asp) to play the p2 files in native format.

Kind regards:
Paul

You didn't read the advise. Before doing any editing, you MUST transcode your 7D footage to either ProRes or DVCProHD. If I were you, I would select DVCProHD.

If you follow this:

DVCPro HD is not 1920x1080 SQ pixels, but 1440x1080 HD pixels (PAL)

[Steve Eisen] "If I were you, I would select DVCProHD."
If you are finishing in 1920x1080 you will (unnecessarily) lose two generations on the H264 stuff, instead of only one going Prores.
Again, going Prores only makes sense if you have to deliver Prores.

Of course it does. You need to convert the H.264 footage to your editing codec BEFORE you begin to edit.

Thus, you need to start over from Square One, which means recapturing the footage and converting it to the edit codec upon ingest, and I hope to heck you still retain your video on the original cards. Watch the link provided earlier to learn the proper way to do it.

Happy New Year..

There's a number of workflows for this situation. I'm in the same boat actually, as I'm not 100% DSLR.

Here's what I can share. If you have the room, Capture your HDV ProRes. But know that when you capture HDV as ProRes, it is 1440x1080, not full raster 1920x1080...so they won't match EXACTLY. But you don't need to. You can capture HDV as HDV, and 7D as ProREs....and just use a ProRes sequence setting. But ProRes is better in the end...easier to work with.

Regarding the 7D files... you'll nee to transcode them. I use MPEG Streaming at this time, and it is freeware http://www.squared5.com/

Best Regards!

Frank
