Looking for Canon 1Dx mkIII raw video files

I have attempted to do just that ... in DR Studio I can isolate the bad points of the clip ... usually one frame ... clip it out and render works ... other times
there are enough that it is not worth the effort.

Most of these are explorations less than a minute long.

Bad news ... or good however you look at it ... I can run a 30 minute external 10bit 4:2:2 recording to ProRes HQ without a flaw ...

So for the pro work I am good ... just any passion play is at risk.

Was so hoping that it was an issue with a Sony G Tough card ... no joy as the Sandisk has the same issue ... and I assume that if I can output a
good stream ... it is just Canon implementing a poorly tested raw internal codec.

Colour me surprised? No really ... at this point in my history I am more than ready to be disappointed ... a bunch of amateurs shucking a product
to vulnerable impressionable clients.

Shame is that none of the YT reviews have done enough work with the cameras to call them on it.
 
I know it's very disappointing and the camera has left a bitter taste, but have you tried any of the other regular modes?

As far as YouTube, anyone who receives a camera from Canon may choose not to or can't share everything publicly (like major issues).

Some people also have more integrity than others.
 
This is a side note and doesn't help you, but just wanted to add that CinemaDNG is such a bulletproof RAW format. Since it's actually just thousands of pictures in a folder, you can open them in photo editing software and export them as JPEGs even if there are dropped frames and put them together in a timeline.

In the early BM days, they didn't have a warning and recording DID NOT stop, so a lot of footage was saved this way and you would just edit out what appeared to be stuttering (dropped frames).
 
A good thought ... I used Cineform raw for years ... disappointed when it was marginalized ... and until there is a better solution CineDNG may
be a great choice ...

I have to say I was spoiled by BRAW and have relied upon external recorders for PR HQ forever ... bad experience recently with a HDMI cable
that died without any apparent reason ... if any of these small cameras had SDI it would answer a lot of concerns. Hoped that the internal raw
with the CFExpress cards would resolve a few concerns ... may down the line but seems like not so presently. Makes P2 and SXS cards look
pretty good at the moment.

Will give a shot at CineDNG ... if I can figure out the workflow ... I have somewhat good memories of importing the pics to LR ... applying a look and
rendering a pleasing stream ... speaking as one who is more comfortable with stills.

Thanks ... just needed to unload a bit ... still would not change the camera for anything south of $16K
 
I think not ... it could be but the HDMI output renders without issue ... more likely early firmware with a bunch
of marginal choices in the rush to market ... Hoped it was a card issue but more likely something that will be addressed in
a future firmware ... although not likely acknowledged by Canon ... improvement on the sly ...

The recently updated the early cameras with a firmware ... which mine has ... but a concern is that they are pushing a Raw
Plugin for FPCX that is worthless for this camera ... but tout it on the support page for the camera.

Marketing and engineering/production seem to be clueless of the message they convey about the coherence and competence
of Canon ...
 
Just FYI, CDNG isn't available on anything new anymore from BM with higher than 30p framerates.

And Lightroom for video was my go to!
 
This is all super crazy to hear. A 40 or 50% failure rate of media files is absolutely unacceptable.

Doc, you really shouldn’t put up with this. Either your specific camera is faulty or something is up with your workflow.

1. You really should upload a problematic clip to Google Drive or similar even if it is 9 GB, and have others take a look. Even if it takes hours to upload (9 GB isn’t that big a deal these days).

2. Have you formatted the cards in camera?

3. In Finder on your Macs, do the file sizes match your expectations? Can’t remember the data rates, but let’s say 1 Gb/ sec. An 8 second clip should then be 1 GB. A 1 minute clip should be about 7.5 GB.

4. Are you copying the media from your cards to a hard drive when using them in FCP or Resolve, or reading them off the Cfast cards?

I’ve looked at a lot of tests of this camera, and haven’t heard about this before.

I do remember some horror stories about the 1 DC, so if this pro line of cameras is manufactured by a different part of Canon than their mass consumer line, maybe their QC isn’t as good.

But this isn’t right at all. You should have a 100% working camera. Even 99% is unacceptable.
 
It is a bit difficult to discern the source of the problem ...

CFEx cards are read ... either in the Mac OS Finder and transferred to a 2TB PCIe memory drive or I ingest them with Shotput Pro 6 ... to the same destination. The card is then removed from the reader ... I have two readers as I wanted to remove that from the chain of suspicion ... one Sandisk and an Angelbird. I do not re-format the card until I am sure I have the media transferred and it is readable ... at least that worked with all my previous cameras ... BMP6K A9II Leica SL. As it is solid state memory it allows for the fastest render times on the Mac Pro. I have tried 4 different CF Express cards ... Sony G Tough 512 Sandisk 512 x 2 and Sandisk 128 which is slower but all my footage is at 23.976 so it will write files ... probably would choke with a 60FPS recording.

After the raw files are rendered in Davinci Resolve ... now morphing into Canon Raw Developer ... they are archived on a Raid ... really important ones duplicated on another Raid.

Cards are only formatted in camera ... sizes match expectations ... and here is the difficulty ... if I open the files in DR Studio 16.2.3 I can edit color grade without any diffficulty ... but when I attempt to render they will fail ... Media Offline error ... which turns out to be one or rarely two frames that are bad in a 5 minute clip. Cut those out and the file will render ... with Canon Raw Developer I get a failure to convert error ... unknown origin to that software.

Because of the problem with DR Studio ... I purchased FCPX 10.4.8 as Canon support page for the camera stated that the Canon Raw Plugin 1.4 supported the camera and its raw files .... the CRP 1.4 installs without error ... files for it appear in the correct folders ... but FCPX acts like it is not working as FCPX does not recognize the .CRM files as a valid file type.

It may be the camera ... I am loathe to send it to Canon until I am sure ... due to Covid 19 Sony has had a Sony 6600 of mine in NY for the past 5 months ... no ETA in sight.

Interestingly ... 4K 10bit 422 via HDMI to my VD PIX-E5/LR is recorded as PR 422 HQ perfectly ... and the internal H.265 4K seems fine.

I am a bit bummed but the files that do render are very very good ... still learning the limits of the AF ... not perfect but really makes shooting as a solo exercise much easier. Who knew that some of the lenses will not allow for slow focus pulls ....
 
- This is not the first time Canon hasn't supported its cameras natively in FCP X after launching them. It personally happened to me three times: first with the XC10 and its new MXF files in which support arrived close to a year after the camera was released (IIRC), then it was delayed with the C200, and then recently last year with the XF705.

- Canon may or may not be waiting on Apple to provide full support for them in FCP X.

- More often than not, many in the same building do not know what the heck is going on. The people that work on the cameras are mentally so far away from the ones that interact with the customers that miscommunications or NO communications should always be expected.

- The HDMI output is completely separate from the internal recording options. You've shared a few times that there is no problem with it and it works great, but it should work great! Even if all of the camera's internal recording didn't work, the HDMI output should.

- Since this is a new RAW format, all software may need some time to fix random bugs. I actually just came across this when I tried to work with Komodo's new REDCODE RAW. Half of the settings didn't work in FCP X. And later I was informed the older DSMC2 RAW is different.

- Really could be your cards/readers. Maybe a one-in-a-million chance, and you are it.
 
I will need to shoot a small clip that does not convert .... the smallest I have is 8Gb ... most 16 - 40Gb.

Some of the older lenses ... my 50 1.2L for instance ... very fast focus pull on the slowest setting ... 16-35 2.8L III works great
as do most of the newer primes.
 
While playing with files in Canon Raw Developer ... I tried a DPX export wondering if the individual frames would allow a successful
conversion ... no luck.

But it engendered a question ... what advantage does DPX 16 Bit have over PR 4444?

Here is a short clip from the DPX conversion ...

No real world visual difference; just workflow related and what's best for the end-user.
 
Are you on auto ISO for that clip above? You have some exposure changes during the tilt.
 
ND filter ramp ... very poor ... at 30 sec you get a great look at my index finger ... shadow at least ...

Was MF and hoping to keep from blowing the highlights ... probably unnecessary ...
 
That's tough to do though during a camera move.

I was actually wondering if the camera had a smooth exposure change setting in it like other companies have. Canon would never do that, but thought for a second that maybe they would surprise us for $6500 and you could use the thumb dials to smoothly change the exposure (via aperture or shutter) rather than abruptly.

That really needs to be next on the list for all cameras; electronic variable ND controlled by your thumb or index finger so DOF and shutter can remain the same.

Groundbreaking necessity along with AF and IBIS.
 
I came so close to buying a FX-9 ... solely for the E variable ND ... but the idea I needed another appendage to get RAW (although 16 bit would be wonderful) turned me off.

My bottom line desire is for SDI ... locking connector with one central 14G wire ...

IBIS when done correctly is huge ... most of my stuff is locked off so I turned it off on most of my previous cams ...

The shame with the intermittent bad raw files is ... I probably ran 5 series of that one shot ... exploring what worked and what did not. The clip I posted was not a success ... but the one that I was satisfied with ... I cannot render.

I am sure that it will get better as you mention ... time and firmware/software improvements.

I am loathe to buy more Sandisk 512 cards at $599 until I can figure out why I am experiencing failures in writes ... or reads.

And a new Mac Pro ... not a possibility ... perhaps a Mac Book Pro ... I have a bunch of Raids with TB 3 but no way to retrofit
that to my 5.1 ... and Apple in its wisdom has locked me out of Catalina/Big Sur ... although the ancient MacBook Air just updated to
a beta of Big Sur ....
 
But do you personally think anyone will notice the difference between the 1DX Mark III's RAW and regular high bitrate 10-bit 422?

Sometimes we are obsessed (I know I have been) with certain features that we think we need and must have, and then once we have them they are not exactly what we were expecting and/or later wonder if we actually really needed them.

Unless RAW has a real world visual difference (and with some cameras it certainly does versus their other internal choices like in the infamous C200), I just don't know if it's worth the time, money and hassle for the overall mediocre improvement.
