Kinochrome - GPU accelerated raw video processing

[ML700D]

Maybe try in PowerShell:

Code Select Expand

./kinochrome.exe | echo

Also what GPU do you have? I suspect Vulkan drivers are missing.

onboard intel UHD graphics

onboard intel UHD graphics

Strange, it should work. Which version of Intel UHD?

[masc]

Indeed there is, it should be straightforward to package it in an .app bundle, I just currently don't have a Mac machine to test it on. Contributions are welcome
I plan to add an option for RCD, which is the default algorithm in Darktable and for which there already is a Vulkan shader written for the vkdt project. RCD should be the default for exporting videos, I need to test whether it's suitable for preview, but at least on more contemporary GPUs, it shouldn't be a problem.

That should be no problem. RCD runs at 11fps for 5.7k anamorphic footage on CPU already (all our grading included on CPU, too), FHD up to ~38fps on my notebook. Great to know that one of the better debayer algorithms is availble for GPU now...

It should be supported. Some more testing on Windows is needed.

Unfortunately, I'm afraid it doesn't support Vulkan.

[Skinny]

Same thing here - trying to run exe and nothing happens, and no output in the command line. Windows 10, Radeon HD4850. I guess this GPU also doesn't support Vulkan.. Well, it was worth a try. Maybe some day, with another GPU..

To all the users experiencing problem with kinochrome not starting under Windows here is a possible solution:
1. Please search for your GPU specs on TechPowerUp, and check if it has Vulkan support in "Graphics Features".
2. If Vulkan is supported by the specs, please run GPU-Z, and check if the checkbox of Vulkan is checked.
3. If it is NOT checked, than you have the same driver bug as I had. The Vulkan driver path is missing from the registry. (Nvidia and Intel both affected!)

The fix:
Nvidia users:
search for file "nv-vk64.json" in your windows folder, and copy the path of it.
Intel users:
search for file "igvk64.json" in your windows folder, and copy the path of it.

You have to put a REG_DWORD entry into "HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\Vulkan\Drivers" with the NAME of the complete path with the correct json file. The VALUE should stay 0.

Nvidia NAME field example:
C:\Windows\System32\DriverStore\FileRepository\nv_dispig.inf_amd64_0afec3f2050014a0\nv-vk64.json
Intel NAME field example:
C:\Windows\System32\DriverStore\FileRepository\igdlh64.inf_amd64_0541b698fc6e40b0\igvk64.json

The path part with the HEX value after the .inf will be different for you, so please doublecheck it.
If you added it to your registry, please rerun GPU-Z, Vulkan should be checked now and try running kinochrome again.

vulkan is checked in GPU-Z but can't run kinochrome

If you start kinochrome from CMD with the following command:
kinochrome.exe >> out.txt

What is the content of the out.txt?

[Jonneh]

Promising tool! Playback for review purposes has always been a bit of a pain with MLVs.

Kinochrome runs fine on my Windows 11 Thinkpad, AMD Ryzen 7 Pro 4750U with Renoir iGPU.

With a 3.5K, 14-bit lossless file (5D3), I get 3-4 fps in MLVApp (simply superb tool for editing, but playback is slow, at least on my machine)---bilinear debayer; with most others it's 2-3 fps. Same fps on my old T470 with 6th-gen i5. When I first launched Kinochrome, files played back in a burst of a few frames, stopping, and then resuming with another burst of a few frames, and so on. Each cycle lasted about half a second, so the overall visual impression wasn't much better than with MLVApp.

I've just updated AMD Adrenalin just in case (initial installation was only a couple of months ago when I got the machine), and now it's playing back much better! An order of magnitude better than what I was getting with other tools (in terms of visual impression, if not fps), so well done!

EDIT: I've been doing some more testing today with a neat framerate overlay called FPS Monitor and I'm getting real-time playback! Just lovely.

A couple of wishlist features would be a basic panel or dialog showing file properties (resolution, bit depth etc) and the ability to zoom in during playback to check focus etc. No idea whether this latter one is even possible.

Thank you!

[EDIT: chatGPT says that this may occur because "on portability subset devices (such as MoltenVK on Apple Silicon), the imageViewFormatSwizzle feature is not enabled by default, and the Vulkan spec disallows creating an VkImageView with non-identity ComponentMapping when that feature is VK_FALSE (VUID‑04465)". It says that you should 1. Enable portability extensions, 2. Query portability features, 3. Choose mapping at runtime (ComponentMapping::identity() or your custom swizzle based on the value of portability.imageViewFormatSwizzle). Whatever that means Btw I have an Intel Mac with an external GPU, no Apple Silicon here.]

Do you have ffmpeg.exe in your PATH or copied into kinochrome's directory?

Now I do

Thanks for a quick noob check-in. Your app might be a workflow gamechanger on this (retro) laptop. MLV playback is smooth, 1GB export to NVENC is a few seconds - great!

Was prepping switching it to Linux and free Resolve with Nvidia accll. I'll take a look at possible NVENC NLE alternatives instead now. Thanks again.

More testing done over the last couple of days. What a great tool---smooth playback, easy export.

I am getting crashes when importing certain files. The command prompt gives the following output:

Code Select Expand

thread 'unnamed>' panicked at src\import.rs:286:23:
Frame size too small
The file opens and exports fine with MLVApp.

EDIT: After importing some 600 files part of a project, only two gave this error, so it does seem to be an isolated issue, but curious nonetheless that both open fine in MLVApp. /EDIT

I mentioned above that it would be useful to be able to check the file resolution. I notice that the Export dialog shows this, and this is easy enough to access. On the other hand, since this tool is potentially so useful for material review purposes, a delete function would be nice (.mlv + .m00).

Welcome! It is a great work of @doktorkrek, I only contributed the NVENC exportability. As long as kinochrome can stay this fast with growing feature set, it is going to be a very nice editor with realtime preview.

Thank you!

[EDIT: chatGPT says that this may occur because "on portability subset devices (such as MoltenVK on Apple Silicon), the imageViewFormatSwizzle feature is not enabled by default, and the Vulkan spec disallows creating an VkImageView with non-identity ComponentMapping when that feature is VK_FALSE (VUID‑04465)". It says that you should 1. Enable portability extensions, 2. Query portability features, 3. Choose mapping at runtime (ComponentMapping::identity() or your custom swizzle based on the value of portability.imageViewFormatSwizzle). Whatever that means Btw I have an Intel Mac with an external GPU, no Apple Silicon here.]

You might have to install VulkanSDK.(https://vulkan.lunarg.com/sdk/home) Do you have it installed?

Yup! Indeed, if you see the error log, it complains about create_info, which afaIu is a VulkanSDK component. So it means that it is successfully finding and calling the VulkanSDK libraries, but that something goes wrong there.

More testing done over the last couple of days. What a great tool---smooth playback, easy export.

I am getting crashes when importing certain files. The command prompt gives the following output:

Code Select Expand

thread 'unnamed>' panicked at src\import.rs:286:23:
Frame size too small
The file opens and exports fine with MLVApp.

EDIT: After importing some 600 files part of a project, only two gave this error, so it does seem to be an isolated issue, but curious nonetheless that both open fine in MLVApp. /EDIT

I mentioned above that it would be useful to be able to check the file resolution. I notice that the Export dialog shows this, and this is easy enough to access. On the other hand, since this tool is potentially so useful for material review purposes, a delete function would be nice (.mlv + .m00).

I would suggest that if you have a github account, please open a new issue and upload your MLV to a filesharing site. The project owner is quite responsive there as I experienced.

....it would be useful to be able to check the file resolution. I notice that the Export dialog shows this, and this is easy enough to access.

Hadn't noticed that, AFAICT the Export dialog dimensions corresponds to the largest resolution of one or more of the imported .MLVs. My noob test folder was a weird mix of whatever presets and crop moods I had randomly punched in during filming

Here, it plays a 2560x1440 losslessly compressed MLV video on a 2012 ThinkPad 430 with integrated GPU in real time

Awesome! Thanks a lot!

• Supports ffmpeg for export, with customizable recipes for video and audio encoding
• Fast multi-threaded CinemaDNG (losslessly compressed) export

Newbie request: in and out points similar to MLV app or, even better, several segments like https://mifi.no/losslesscut

If that's possible with ffmpeg but cumbersome within your code I'd also be happy to know. Pardon my ignorance if such a feature is impossible with raw media.[/list]

A couple of wishlist features would be a basic panel or dialog showing file properties (resolution, bit depth etc) and the ability to zoom in during playback to check focus etc. No idea whether this latter one is even possible.

It is very much possible. The code is structured to have a clear separation between the UI and the processing code. I have added zooming with the scrollwheel and dragging with the mouse, you can try it in the newest build. Regarding the file properties, where would you find it convenient to have them displayed?

Testing on MacIntel here, won't launch. [EDIT: added more details in log after setting RUST_BACKTRACE=full]

Ah, the code to pick image format for font textures was checking for features that are supported, but not necessarily enabled and this image_view_format_swizzle is not enabled by default on portability devices (such as MoltenVK)... Fixed it, try now please.

I am getting crashes when importing certain files. The command prompt gives the following output:

Could it perhaps be because they are .mlv + .m00 files? They are not supported yet.

It should not be a problem, I can add it.

I would suggest that if you have a github account, please open a new issue and upload your MLV to a filesharing site.

You are welcome to! Alternatively, if you don't have a GitHub account, you can just send an email with your issue to the mailing list at ~grego/[email protected]

Works absolutely flawlessly, both zooming and panning once zoomed. Brilliant! One oddity to report about it though: if you place the cursor somewhere over the video frame or black bars, scrolling zooms the video (and only the video), but if you place the cursor over the file list, scrolling still zooms the video instead of only scrolling the file list.

Regarding the file properties, where would you find it convenient to have them displayed?

I suppose at the bottom of the edit panel on the right would make most sense. I think resolution and file size would be most useful to be able to see at a glance, and maybe full properties adding camera, lens, aperture, bit depth, compression, frame rate, audio (y/n), date created could be shown from a menu entry?

Any chance of adding time elapsed/total above the playback bar too?

If deletion (from project, disk, or both) could be added, this tool will be the best we have for initial review purposes in my opinion and will be an immediate adjunct to my workflow. I love the fact that loading a project doesn't necessitate reimporting all files, seemingly the case with MLVApp and unfortunately an annoying time sink each time a large project is opened (30 seconds for Kinochrome vs 15 minutes for MLVApp for a 600-file project).

Could it perhaps be because they are .mlv + .m00 files? They are not supported yet.

They are indeed .mlv + -m00, although all of my recordings are, and Kinochrome didn't baulk at any of the hundreds of others I've opened. Whatever the cause, it very much seems like an isolated case, but even so I'll try and send the file over via GitHub or email.

One more potential feature I wonder about: MLVApp shows tiny thumbnails next to the name of each file in the bar on the left, as follows:



This is very useful for knowing what's what in a long list of files. Would that be feasible in Kinochrome?
