Two problems with the XF305 at DVinfo.net

Vincent Oliver · January 30th, 2011, 06:07 AM

Does anyone else have a problem with the continuity of video clips, I have recorded three stage productions using the XF305 as my B camera (Sony EX3 as the A camera). The XF camera splits the clips up into roughly 7 min chunks. The problem I have is that the joins are all over the place, a few blank frames, jump in sound, pixelation etc. The clips steady out again after approx 15 seconds, this does mean I lose 15 seconds between each clip . Fortunately I have been able to cover the lost “footage” with the EX3 material. My worry is that I may not be so lucky on the next shoot. I am using 16gb Lexar Professional 300X CF UDMA cards.

The other unrelated problem is that when switching to the No 1 ND filter, there is a heavy pink cast – any ideas? Has anyone else experienced a shift in colour (color)?

Otherwise the XF305 is a nice camera, great clean shots, but still love my EX3 more :-)

Oliver, I have record several events that are several hours long and have not found any problems when I put the files together. It all looks good to me. No lost frames. Nothing.

I am using either ScanDis 64 gb Extreme Pro or Adata 533x 32 gb for memory.

Good luck in locating your problem. James

Vincent Oliver · January 30th, 2011, 03:11 PM

I suspect it is a memory card problem, or perhaps my memory card reader. I will continue with my search for the answer.

Thanks

Regards Vincent

I have never seen the 'continuity' problem with the many XFs I have shot with.

Not sure what you are using, but USB readers can be a problem, as can unsupported cards.

Good luck!

Vincent Oliver · February 2nd, 2011, 01:37 AM

The Lexar USB reader together with Lexar Professional 300X 16gb cards. The end of each clip (aka chunk) when viewed in camera doesn't display the same garbage that is visible in my NLE. However, there is a pause in the continuity when pre-viewed in camera.

Nick Wilcox-Brown · February 2nd, 2011, 02:40 AM

USB is not great for moving large chunks of data. I have seen errors in the past with still images (corruption of files). Try a Firewire 800 reader, it will cut copy time to around 1/4 or less

Vincent Oliver · February 2nd, 2011, 02:58 AM

Thanks for the suggestion will give it a go, although I have never had any problems with transferring large amounts of data from my EX3 using the same USB reader.

I didn't read this carefully enough. It must be card related, especially if the USB Reader is 'known good'

Vincent Oliver · February 2nd, 2011, 03:26 AM

Yes, I am also suspecting it is a card related problem, I will get on to Lexar and ask them to send another card.

Thanks for taking the time to respond.

btw. do you have a XF305 or when you used it did you notice a shift in colour when switching in the ND filter. I had (have) a similar problem with a XL1s although I rarely use it now-day's.

As I point out in my XF305/XF300 training DVD, Canon says that you should re-white balance when you change ND filters. Apparently they did not build the filters to very close tolerances.
Personally, I have not noticed any problems when changing ND filters, but Canon does warn you about it.

Vincent Oliver · February 2nd, 2011, 07:01 AM

Thanks for your input Doug, changing white balance for every change of ND is not always practical, and in an ideal world shouldn't be necessary.

Here are two shots taken approx 20 minutes appart. The pink cast is with X64 ND and the other is with X16 ND, both were shot with a white balance of 6200k.

These images are reduced in size for display here, but should give the idea.

Doug Jensen · February 2nd, 2011, 07:39 AM

Hi Vincent,

Oh, don't misunderstand me, I'm sure the problem exists. I'm just saying I've never noticed it first hand. Also, I think is is inexcusable for Canon to build a professional camera with this flaw. I'm on your side, just merely pointing out that Canon does warn about it in the manual. I think that's better than just ignoring the issue altogether.

Vincent Oliver · February 2nd, 2011, 07:47 AM

No misunderstanding Doug, I hear what you say. Like most issues on any camera there is always a workaround. My Sony EX3 has the IR problem, which can be resolved with a filter. The pink cast on this XF305 can be resolved with a new W/B etc. It just seems that we are the ones who have to solve the problem, wouldn't it be nice if manufactures got it right

Hope your XF300/305 DVDs do well, I certainly found your EX3 DVDs to be invaluable and a great reference.

Jay Massengill · February 3rd, 2011, 12:48 PM

How did you transfer your files? Using the included Canon software? I haven't shot any long files with my XF300, but in the past when using an AVCHD camera and long files, the software was required to transfer the split files correctly without glitches at the cut points between sections.

Bo Sundvall · February 4th, 2011, 09:21 AM

Hi

I saw the different images from the XF300 in the post above. It seems unbeliveable that there can be such huge difference in colour just by switching ND filters. I have a XH-A1 myself and have never noticed any color shift by switching ND filter. I've also checked tha manuals for both the XH-A1 and the XF300 and both manuals state that there can be a colour shift when switching ND filter and that a new WB might be made. Can anyone confirm that the colour shift between the different ND filters is so dramatic as the above pictures indicate? For me it seems as if the camcorder is using two completely different picture profiles, not just different ND filters.

Regards,

/Bo
