Panasonic GH5 test videos don't work in Resolve 12.5

PostThu Jan 05, 2017 2:29 am

I know the Panasonic GH5 isn't released for a couple of months, but Neumannfilms posted a video here that shows videos they took with the GH5:


They made the videos available to download here: http://www.mediafire.com/file/m5rrourqi ... ootage.zip, and I downloaded them and tried opening them in Resolve 12.5 to see if they'd import as I plant to get a GH5 when its released and would need to edit my videos but I just got a "Media offline" message.

So for those who use Resolve and want to get a GH5, we will need a way of opening them in Resolve, unless there is something I am not doing that is causing them not to work when imported?

I would guarantee you this camera is using an offshoot of H.264 or H.265 to capture the files. Does Panasonic offer a utility to convert the files to a better format for post? What does the manual say?

I opened one of the 10-bit 4:2:2 videos in Media Info (this: https://mediaarea.net/en/MediaInfo) to see what codec it was using and exported the codec information. Its in the text file in the attached zip if that helps.

The problem seems to be with the 4:2:2 encoded clips. The 4:2:0 clips load fine.

Hopefully BlackMagic will fix this so that you can optimize media from within DR and not have to encode externally.

in this particular case the 4:2:2 clips use 10bit depth per channel, the 4:2:0 60fps examples utilize only 8bit!

200Mbit (max) 10bit h264 4:2:2 with full range flag. This is somethings like XAVC Long Gop 200, but Resolve is not ware of it. Full range flag is another "issue" as without proper support from BM side, these files will be read automatically as Video range. Lets hope BM adds proper support for them.
And of course it's MP4 with PCM audio, which is against MP4 standard. At least we use to it as Sony does the same. These big companies first create standards and later don't even bother to respect them :)

Are these straight out of the camera? Strange- there is 0 additional metadata.

concerning the conformance of PCM in MP4 containers, you can simple choose the MOV container option on the camera... just the same as for the GH4...

Hopefully BM can handle it, because the GH5 will be my next camera.

At release the GH5 will max out at 4k30 10 bit 4:2:2 150mbps, but Panasonic has already said an early summer firmware upgrade will push it to 400 mbps, and might bring in hvec support as well.

Yes, because Resolve expects that mp4 will be 4:2:0 8bit.

FWIW, the 4:2:2 10 bit files open up fine in an old version (V2) of Convert (ffmpeg) and play fine in Media Player Classic. So I'm a bit surprised as to why these files are too exotic for DR to deal with. But maybe I shouldn't be. At this point I wonder if DR would simply be better off by dropping all support of h.264 and its variants given their track record of mediocre support. The reality is that the DR limitations with h.264 push you strongly toward converting anyway.

I'm almost sure technology is already in Resolve to handle such a clips, they just have to adjust Resolve to be able to properly recognised them.

I already trans-code to dnxhr using ffmpeg before importing into DR, but some times It's nice to go strait to DR when all I have is a small clip or two that needs minor tweaks.

I try to avoid external transcoding and prefer to let DR create optimized media. It makes for less things for me to manage. So truthfully, as a practical matter it would not be good for DR to drop h.264. I guess I'm just griping about the h.264 support - which is pretty unreasonable of me since I'm using the free version. (
) OTOH, if I paid the $1000 for the full version I'd be severely disappointed in the h.264 support.

So I guess the thing to do is to just remember that DR is a top tier color correcting tool (and well worth the $1000 for that) but still struggling to get to that tier as an editor.

I use ffmpeg to do it, because it does it substantially faster. I can transcode files in parallel, and I can off load the h.264 decode to my gpu (thankyou Nvidea) so all the cpu has to do is encode the dnxhr.
https://developer.nvidia.com/nvidia-video-codec-sdk

on my machine I can take the UHD h.264 source from a Pansonic G7 and transcode it to dnxhr SQ as well as down sample it to 1080p, and average 180fps.

I wish BM would consider taking advantage of the Nvidea api.

I thought it odd that Panasonic and Sony would operate outside the MP4 standard, so I did a little poking around. The audio in the uploaded GH5 files is described as using the "twos" CODEC. Further digging reveals that this refers to "twos complement" linear PCM. Linear PCM is supported by the MP4 standard according to the Wikipedia article video container comparisons and the "twos" CODEC is also listed on the MP4ra.org website as a registered CODEC.

This isn't my area of expertise, but it looks to me like the use of "twos" Linear PCM may very well be within the MP4 standard.

This is what people with correct knowledge say:

"ISO 15444-3 - the specification that allows raw audio - defines that such files have the brand mjp2 (which is currently not supported by FFmpeg for output files) and not mp42. I wonder how Sony explains the creation of such files."

Panasonic (and I'm almost sure Sony's) files are "mp42", so PCM is not allowed there and that's why so many tools (including Resolve) had problem with it in the first place. If it would be supported for long time then I don't think so many tools would have such a problem with it.
Maybe it was added recently, but I'm yet to see any official info.

Keep in mint the test footage was from a pre production unit, I've seen some content claiming firmware versions as low as 0.3. In other words a lot of stuff still need works out.

according to this video "formats" are AVCHD, MP4, MP4(LPCM), & MOV.

My GH4 is not pre-production and it shows the same "twos" audio CODEC. Further, the menu refers to LPCM audio rather than simply PCM audio - the same as in your referenced video. It seems unlikely that the pre-production status of the unit is very relevant the the PCM/LPCM issue.

hmmm... -- i think, you are right! :)

mp4ra.org (=apple) is indeed mentioned in most relevant specifications and RFCs as the central source of registration. thus quicktime and mp4 should work the same even in this respect!

It's not really saying much at all and if anything than fact that it's defined in MJ2, which aligns with post from ffmpeg developers. Sounds like some special case and does not apply to standard "mp42" MP4 files.
It's also less important as most tools do support it now anyway. If you are a big company you can force things to happen regardless of their correctness or not, beauty of corporations :)

I think you are misinterpreting the context of that listing. That is an MP4 listing, not an MJ2 listing.

MP4 is not described by single type. You call it MP4, but inside many things can be different.
Read reply form ffmpeg developers. It explains when TWOS is allowed, which seams to be aligned with http://www.mp4ra.org/codecs.html.

"ISO 15444-3 - the specification that allows raw audio - defines that such files have the brand mjp2 (which is currently not supported by FFmpeg for output files) and not mp42. I wonder how Sony explains the creation of such files.

In order for MP4 to store TWOS as per spec brand (I assume type of MP4) has to be mjp2, which is not the case for Panasonic nor Sony files.

If you like wiki (https://en.wikipedia.org/wiki/ISO_base_ ... ile_format):

"The JPEG 2000 specification (ISO/IEC 15444-3) defined usage of Motion JPEG 2000 video compression and uncompressed audio (PCM) in ISO base media file format (.mj2)."

which for me sounds like: using TWOS=specific case.

In other words- TWOS is described in (ISO/IEC 15444-3), so in order to use it MP4 brand has to be mjp2, not a more common mp42. This is how I understand it, but I may be wrong.

yes -- it's an extendable format.

(see: https://web.archive.org/web/20080714101 ... /index.htm)

if a codec type is registered at mp4ra, it can be supported by MPEG-4 implementations in a satisfying way. but you should not expect proper support by all implementations. sure, it's somehow irritating, if a particular codec works in .mov files but not in .mp4, because both containers use in fact the same mechanism to register extensions, but that's life.

This image also confirms ffmpeg developers statement. If usage of TWOS is described in ISO/IEC 15444-3, then you can't use it in mp42 brand (14496-14/15), as they are not part of each other.
In order to use TWOS you need to use ISO/IEC 15444-3 brand, but this does not allow video codecs like AVC, as it's mainly about JEG2000.

Someone can also say that whatever is inside ISO can be supported (regardless of which parts has description for it), but technically this seams to be against spec.
ffmpeg devs still to refuse add PCM support in MP4 on export.

take a look at:
https://en.wikipedia.org/wiki/ISO_base_ ... Extensions

PCM encoded audio is not mentioned in MPEG-4 Part 3 (=MPEG-4 Audio), but it can be supported as an extension.

that's a wise decision, to maximize compatibility, but it accepts PCM on ingest. that's why we are able utilize this tool to rewrap files for use in more picky applications.

The video is about the GH5, and as a software developer, I can tell you when you see version numbers below 1.0, you need to take everything with a grain of salt. What you think you are seeing/getting is often not the case.

My GH5 is on its way. It would be awesome if Resolve can add support for the 10 bit video files GH5 uses. Until then I have to use a 10 bit build of ffmpeg and pray that it does the right thing...

Hi David,

I have downloaded Panasonic Lumix GH5 sample movie: Low Light / C4k / 24p / 10 bit / 3200 ISO / Cinelike D and Quicktime player does not play it. VLC does not read it, etc ...

With the only capable soft can read : Virtualdub Filtermod and I just convert it to PRORES 10 422 HQ (info obtained from this version).
(Officially, there is no PC codec for the GH5 10 bit)

Obviously, Davinci Resolve knows very well how to read this file.

Jean Claude, VLC 2.2.4 plays it fine. Premiere Pro plays it fine. Could be because you're on a Mac and behind the curve a bit?

Unfortunately, the three non-60p clips from the OP in this thread continue to show "Media Offline" in DR 12.5.5, as well.

Incidentally, Pegasys (TMPGEnc) Mastering Works 6 imports the GH5 4K 10-bit files perfectly well:

http://tmpgenc.pegasys-inc.com/en/product/tvmw6.html

Unfortunately, Resolve 12.5.5 (free Windows version, at least) won't accept the 10-bit High-444PP-Intra and High-422-Intra MP4 transcodes produced by MW6, which uses (licensed) x264 for H264 encoding, but with GoPro Studio (Quick) installed it can convert to Cineform.avi and Resolve will accept those encodes.

I'm not sure what bit depth MW6 processes at though.

Jean Claude wrote:With the only capable soft can read : Virtualdub Filtermod and I just convert it to PRORES 10 422 HQ

I'd forgotten about VirtualDub FilterMod. So Cineform could be an option there too.
Edit: After testing that - for some reason Resolve doesn't see the Cineform.avi transcodes, but after rewrapping to mov it does and imports them OK.

I just tested my TMPGEnc Mastering Works 6 (I had forgotten that one ...): it reads the file well but it is necessary to rename the file because the name is too long for the encoding out.

I tested in MOV and in Davinci Resolve 12.5.5:
- cineform millions + (1,590,353Ko)
- blackmagic 10 bits (6 410 705 Ko but oddly a little darker than cineform)
- DNXHR HQX (12 bits) (1,049,680 Ko identical to cineform)


Really beautiful pictures ... :)

You have to make sure that TMPGEnc preserves 10bit pipe in case of Cineform or DNxHR as target. It's not that obvious.

There is no need for one- any software with full spec AVC decoder will do (but not capped to 8bit 4:2:0 files, like QT).
Latest Adobe apps should have no problem with GH5 10bit files, sou can use AME and convert to e.g. Cineform or DNxHR (just don't forget to tick Render at Maximum Depth)
Latest AME on Mac loads these files fine. There may be some issue when you use Full Range, like sample form the link above.

Hi Andrew,

Until now I go through Mediainfo to get information on the clips but it is mainly based on the metadata. Do you have a program (windows) that tests the actual depth of the clips?
For the clip DNxHR HQX media composer sees it in HQX (but is it a truth?) :?

The only clip say "10 bits" is from BMD Codec 10 in a mov => then ?

Edit: and the only app that tells me (explicitly) that input is a 10-bit clip => it's VD pfmod to prores (do not be fooled it's a library based on FFMPEG) ... can Be the same as Premiere or BMD? :?
