My Canon XF400 just got a firmware upgrade that allows me to record in Canon XF-AVC (as well as the existing MP4). I've attached a sample of the footage (120MB) and it contains:

  • MXF File : Video File 3840x2160@50fps H264 @ 160Mbps with 4 x Mono LPCM 24Bit/48 kHz Audio

  • THM : Thumb Nail File

  • XML : The Meta Data for the cip (note: this was shot with default settings, Auto everying + Wide DR Gamma)



The MXF file imports into PD16 just fine (well only one audio track appears but we know about that PD limitation already), but I can not see that it is using any of the Meta data from the XML file . So it has me wondering..... Is there any befefit to shotting in XF-AVC with PD16?

Thanks

It is my understanding that the XF format is supposed to have some advantage for professional film makers, although I can't remember what the advantage is right now. For my purposes I would rather have a high quality mp4, at least as an option. Maybe after a software upgrade I will feel differently since MXF take a lengthy extra step for me. On my camera I can shoot 1080 in either format, so when the weather clears up I eill go outside and shoot some teats and compare them. __________________________________

The actauly "quality" of the video should be identical as XF vs MP4 is about the container that holds it. Edit - That said I see that XF records 4k @ 160mbps, and MP4 is 150mbps. What I've found so far is that several NLE that use the XML data associated with the clip but I have no idea how it is used (if at all) in PD. Unless there is some clear advantage to XF (which I'm currently missing), I'll probably stick to MP4 as well.

Hi Nathan,
Actually PowerDirector never claims to support MXF, you are lucky if you can edit it normally, maybe you have other codec link QuickTime installed? ------------------------------------------------------------------------------------------------
