Vincent,

Steev Dinkins on this forum says he had problems with the Lexar 32GB 300X. Is this the same card you used? He also said the Lexar 16GB 300X works, but not in overcrank mode.

Glen, the tests I have just completed this morning were all a normal recording, both Lexar cards are 16gb (300x & 600x)

I use SanDisk Extreme 60mbps cards. Don't know spec-wise how they compare to the transcend and lexar but theyve never missed a beat.

It would be wise to stick to only these brands of card that have been tested & approved by Canon paying attention to the small print e.g. Lexar, Transcend & Delkin cards are not suitable for over-cranking & 32GB Lexar cards should not be used at all.

The SanDisk should work OK at 60mbps, the 600x Lexar is approx 80mbps and the 300x will be approx 40mbps. Maybe 40mbps is too slow hence the garbage frames.

300x is 45MB/s that's megabyte, guaranteed sustained write speed. The FX300 stream is 50 Mbps, that's megabit, so the Lexar can write at about 8 times the speed of the input stream.

Thanks Eric, I guess that throws my theory out of the window that the 300x Lexar card is too slow. The bottom line is that the 300x card corups my test clips and the 600x card doesn't

Whatever the claimed performance of the Transcend cards the fact is that Canon have tested them & do not recommend them for over-cranking.

Unfortuanetly there doesn't seem to be one single up to date list of Canon approved cards but here are some of them
Canon Professional Network - CF card compatibility for XF305 and XF300 pro camcorders
The CF cards whose compatibility with XF305/XF300 has been confirmed

I note that the16gb Lexar 300X card is listed as being compatible. This is the card that has caused me problems.

I will do some more testing later today. I have used Lexar cards for many years and they are excellent, the 16gb card works well in my DSLR camera. I just wonder if it is not fast enough for the XF305. The 600x is a perfect match.
