Hi Ken,

I am surprised you can see it on the LCD, if that is what you mean. The video is running at 25 fps PAL and to me you could only pick that up frame by frame in an editing suite or on 35mm film by hand, I find it difficult to understand that one frame would make any shift ??????????

Why do you need to take one frame off a clip, which you can do of course. I still say you can fix that in Canon Digital Professional ? I go back to my days in 35mm movie film and there is a difference all be it slight from frame to frame. Maybe I do not understand what you are trying to do ?

If you mean shifts in clips of movie shots say, five seconds to the next five second clip, then the ambient light may change the color temperature and the human eye will not notice it , but, the camera will.

My son using a 5D Mark II accidentally moved the AWB setting just a fraction and set an indoor setting more than slightly green under fluorescent lights the 5D would have corrected it, set on neutral AWB.

In my experience with a 5D mark II this may happen sometimes if you do not get the exposure correct or the camera is slow adjusting between shots, a shift in exposure although slight will effect the color. If you shoot in RAW only this can be fixed in Canon Digital Professional & but, perhaps not Adobe Photoshop.Do not shoot in JPEG.

Check the LCD for obvious over exposure of any shot, and re shoot.

Most digital cameras tend to over-expose, I suggest you alter the adjustment to -1, this will reduce that (in the highlights) except for average ambient light.

We use two of these cameras and have never lost a good shot in 3.5 years.

Good luck
Ps I understand it is a 7D (it may not operate the same as the 5D and you say you shoot in RAW H.264) but, that is the movie codec H.264 mov not stills. Unless I stand corrected ? Also, if you use live view you may get average exposure as for video ( as that is how it operates, not as I presume you have set it as evaluative. The Canon manual states that the exposure for video is not the same as for stills, and you cannot change that.

I agree with Brett & John, however I have used the Canon 5D Mark II for a live in concert jazz band performance in High Definition 1920 x 1080 and a brass band in Budapest using an external Rode Stereo Mike, to say the least the video and many still images were broadcast quality and edited in Premiere Pro and Sony Vegas.. The Jazz concert was reduced (if you could say that) to HDV/mpeg-2 at 1440 x 1080 for pro tape and you could not tell the difference on a Sony 46′ HD 1920 x 1080 Monitor. ,You could tell the quality difference between a blu-ray disc at 1440 x 1080 or 1920x 1080 and a standard DVD at 720 x 576 PAL . It is just a matter of personal preference.

The low level light performance of this camera (because of the large 35mm sensor) compared to a Canon HDV video Camcorder or the Canon XA-10 without very good lighting is noticeable. Rent both and see what you think.

Ps. Be advised that the Canon outputs H.264 mov clips which are very large and the other Canon, AVCHD the professional 25 mbps not about 12 mbps as per the consumer camcorders. You will need to have a i7 Quad Core with either Sony Vegas Pro10 or Platinum 11 at $119 or Premiere Pro CS5 5.5.1 at $1600 Aud. The Sony Vegas Movie Studio Platinum 11 is only a 32 bit of software gives a professional performance.

There may be some artifacts appear on the monitor screen in PP, because of its size, even the screen resolution on Sony Vegas can be altered from High Resolution to say “Draft Mode” ? but, when shown on a say Sony Bravia 46″ HD 1920x 1080 Monitor, (when edited at HDV/mpeg-2 avi 1440 x 1080 all should be well)

You should not have to do any of that, you can see if the mic is working re LCD or is it different to the Canon HV20/30/40. Never had the Rode Stereo Mic fail ? Good luck !

For what it is worth, my son in Media uses a Canon 5D mark II and uses iMovie not FCP , it works automatically and may not have all the settings as in FCP no, issues. We are PAL here and use 25fps, In an i7 64 bit and Sony Vegas , but, you probably have set the input settings correctly, but, just check it ?

Hi Ben,
I have never had a freeze although 3 years ago this model only ran @30 fps NTSC not PAL @ 25 fps which was was fixed by a FIRMWARE update from Canon (amazing technology). However, there were problems changing the speed to Broadcast PAL using Premiere Pro.

I recommend not using 24fps which is to Cinema Projection , Canon’s recommendation is that the shutter speed is best set at 1/50 sec which is the normal speed for their camcorders. This or even slightly higher TV settings produce a very smooth video and eliminates any jellowing movement effect or pixel destabilization when panning too quickly.

We have 2 Canon EOS 5D Mark II producing broadcast quality video .

Ditto Greg,
I have used 9x SanDisk Extreme IV 4.0 GB and Extreme 60mb/s 400x 8GB but, Ultra II may be a bit slow for video at 1920 x 1080p.

Best to set Canon 5D mark II at TV 1/60 sec and let it find own aperture for smooth running and only go to 1/125 tv if exposure not right.

Used the camera for 3-4 years all Firmware upgrades to 2.0.9 and had sensor cleaned once by Canon Service.

Overall performance with Image Stabilized Lens outstanding on stills and 1920 x 1080p H.264mov video. Mainly to Pro tape or Blur-Ray disc via Sony Vegas Movie Studio Platinum 11 or Premiere Pro at least 25 productions, no problems. A i7 64 bit Quad Core with Nvidia Quadro Fx 3800 is a help.
