canon 5d markII and h.264 problems
on Sep 26, 2009 at 6:09:07 pm

anyone used the new 5d mark II for video?
I had a friend help me shoot last weekend and he brought his shiny new canon 5d and shot (unfortunately) 1080p with it, native Codec is h.264,

now then...
Im editing in **standard def (720x480i)** with FCP HD v4.5on a G5 Mac running OS 10.4.11

have tried to export h.264's as "None compression" .mov's then re-import to mix with 480X720.mov files.
when i do that, I get a *lot* of moire pattern especially in contrasty patterns like grass or a straw hat. Also image is somewhat degraded throughout.

having said that, if i export as h.264 then all seems well ... but I have trouble with *any* other codec.

a friend suggested Mpeg encoder (freeware) and some settings dont change a thing but a few seem helpful.
Moton jpeg seems better ... although in editing mode (FCP) it still looks ***horrible***.

Only upon output does it seem to improve the quality.
I am tremendously confused.
what is the weak link here?
anyone have ideas for me? I desperately need to edit this stuff and burn a DVD.
thank you

You have to use compressor and convert it to codec: Apple Pro Res, High Quality, for Progressive Footage.
Not sure if FCP 4.5 will work with this though. That's how I do it in FCP 7 and it's perfect.
Good Luck.

thank you
One more Q: how would that intercut w the Standard def interlaced footage?

that I don't know but I know that FCP 7 is the only one that (easily) lets you combine formats in the same timeline. Have you checked out dvxuser.com? They have a pretty good knowledge base and forums as well. Lots of posts about people trying to mix footage. Good luck.

FCP Version 4.5 doesn't have ProRes. That turned up in V6. You will need to convert using compressor to whatever SD codec you are able to work with. Match it to your other footage. Otherwise work down from uncompressed to DV50 (or DV if desperate.)

Don't forget to convert the audio to 48khz at the same time. This camera has generated tons of posts here as it is a great image wrapped in a non editing codec with the wrong frame rate and audio sample rate.

Canon really should fix the obvious mistakes, but it will always need transcoding into an edit codec that FCP understands.

So, in a nutshell, this is difficult at best.
and Im further hindered by the absence of the ProRes option.
(Version 6 eh? good to know)
Is v6 still powerPC version or intel?

PS I have been trying this. (most of the afternoon, Ug!) good to know at least Im on the right path.
"Mpeg encoder" improves the quality a great deal (especially the free price-tag) and it can batch files so I don't have to babysit the machine.

Successes (& degrees of):
10 bit uncompressed looks good ... as does 8-bit uncompressed
Motion Jpeg looks good
apple intermediate codec looks good.
animation looks well, *pretty* good

outputting to h.264 again looks almost as good as the above.

on the downside:
dv50pro looks like hell no matter what.
none compression ditto

thank you to Brad and Michael for clearing some of this up.

I realize this last call is a longshot but if anyone else has an idea for me, please chime in!!
thank you

well, im afraid compressor works well but takes longer than i have to give it.

for now Im sticking with chewing gum, rubber bands, FCP 4.5HD and an equally old version of after effects.
incidentally, Im extremely hesitant to say this but ...I think i finally have it worked out.
I tried Mpeg exporter and that was indeed a handy program. however it lacked control over the *pixels*. Also tried FCP, compressor, quicktime, and I finally went back to After effects and discovered a plethora of options for pixels.
... and believe me it makes a difference...

Pixel choice changed the actual *shape* of the frame (longer vs shorter), thereby compressing the image (horizontally) and causing angular things to compress and not match up properly.

In after effects, I clicked the box for D1 instead of the native *square pixels* and voila.
some angular things still have occasional blocky edges *within* FCP ... but sharpen up nicely to their *intended* look upon output.
(this may simply be FCP 4.5HD showing its age.)
fingers crossed.

While we are talking about the 5D, I'm having issues editing a few clips shot on the Canon 5D. I've edited all kinds of footage on my system before including Red footage without a problem. But I cannot successfully play anything on the time line without it stuttering or stopping due to dropped frames. I lowered the RT to Safe, to Unlimited all sorts of things but nothing is working. Any advice?

what codec were you using?
just h.264?
or Prores?
or apple intermediate codec?
if H.264, perhaps it was due to the high compresssion?

You should use either compressor or mpeg streamclip (which is faster) to convert your footage to Apple Pro Res 422 and then import into FCP.

This will change your frame rate and file size to be much more manageable.

Here are two helpful tutorials:

Hope this helps!
