Is there anywhere that I can download some original footage for me to test.
Need to know if my pc can handle the 300 mbps or if I need an upgrade.

After 125 views nobody can provide a test sample?

There are links to some 'untouched' sample XC10 UHD footage (on Vimeo) at the end of this review:

Canon XC10 extensive camera REVIEW (http://gadgetflux.net/canon-xc10-review/)

I downloaded one sample and, after adding the .mxf file extension, MediaInfo reported it to be 3840x2160 AVC (High 4:2:2 Intra@L5.1), 290Mbps, and the 'writing application' Canon XC10 1.00. So it is surely the original footage straight from the camera.

I was looking for a sample myself. I've been doing some tests to see how several linux NLE's deal with different video formats.

Edit: There's also this one:

CanonXC10 4K 305Mbits/sec Test Footage on Vimeo

The file download options include 'the original MXF footage', but having examined the download MediaInfo reports the 'writing application' to be Adobe Media Encoder, so it must have been passed through Premiere.

Thanks you so much for the link.

You're welcome.

BTW - regarding the second sample video:


The file download options include 'the original MXF footage', but having examined the download MediaInfo reports the 'writing application' to be Adobe Media Encoder, so it must have been passed through Premiere.

I note also that MediInfo reports it as being 10-bit, and DaVinci Resolve identifies it as XAVC. So it's definitely a transcode.

Yes you are correct it is not an original file.
It has be transcoded with AME.
