Video Artifact editor for V-DSLR and consumer cameras

  1. Ah, that's a shame. Maybe a solution for you would be to consider creating an OFX plug-in, which will work on a wide range of software on Mac, Windows, and Linux.
  2. This is very cool. Right now I'm using things like "notch filter" in nuke reformat nodes to deal with this stuff, but this could work much better for specific problems. Is there any possibility of some type of gizmo in nuke for this? Heres the common problems I use notch for and it's not applicable in about half the cases:
    1) expanding 8 bit to 16 bit color space (especially going from a 8k to 12k stitched 8 bit "image" to a crop at 2k prores 4444)
    2) camera operator screw ups, like moire or wierd artifacts like gate flares
    3) compression artificats (the nuke notch works fairly really well going from quadhd to 1080p, but I don't have anything that can deal with compression artifacts when I'm not reducing pixel count)

    I btw do compositing on windows (grading is in mac) with a z840 m6000, so having this run on the "compositing side" before it it sent to grading is where it would fit in my workflow.
  3. I have experimented with Boris DV Fixer, which can work to a point with crappy interlaced material. That plus some careful NR and sharpening helps, but there are limits in turning chicken manure into chicken soup.

  4. I can suggest this workflow for users with Mac who still use consumer sources:

    Compile very cheap AMD 6 Core or i5 4 core computer: a cheap MB with USB3, a processor, good cooler, a cheap power block. An internal video card is ok, 8 GB ram, 1 SSD disk and 1-2 USB3 disks for processing and material exchange between computers. A very cheap Full HD monitor is sufficient, because it if for artifacts, not for grading. Windows Professional x64. This will give ~3-10 fps for Full HD sources and 1-5 fps for 4K.

    I personally use 2 computers, but I have hundred hours of sources from cheap consumer cameras. Any good camera for my work costs minimal 5x money than my software costs. I create education psychological films. And now I shot in 50p from 2 cameras + audio recorder.

    My workflow gives me simple transition: MTS files from 2 cameras → Video Artifact source prepare and restoration in batch mode → MOV → DaVinci mound and grade → DNxHD → Video Artifact mastering → consumer distribution webm VP9 in 1080/720/360/240p.

    Also I can extract WAV files, denoise them or recorder sourcs in an audio editor using best denoiser software and return resulted quality audio back to Video Artifact.

    In mount and grade phase I have clean sources with small film grain amount. No any filtering is required. So I can grade and mount in real-time for 50p 10-bit sources.

    I tried to emulate some features on DaVinci Resolve and Fusion, but it is unreal slow and it is not ready for practical use on my side. I had 5 fps only for reading and write with very simple filters. Any external OFX will dramatically slowdown processing up to 1 fps where Video Artifact gives 20 fps. I do not understand how to use these OFX stuff for practical needs without a great multi-computer farm with very expensive setup. Any GPU to CPU and back transition eats many processing time. So I understand why some restoration software have no prices.

  5. Right off the bat, I'd suggest you avoid shooting on cameras that record M2TS files. To me, M2TS is a delivery format for disc, not a format for post. Find a camera that will create reasonable files that easily work in your editing and color-correction workflow. As one example, the Blackmagic Pocket Camera will shoot 10-bit ProRes 444 right out of the box. When you start off with a highly-compressed 8-bit format, it's downhill no matter what you do to try to save it.

    The inexpensive Canon/Nikon DSLRs are not great, but they do at least have reasonable color and dynamic range and are workable to a point. They record to 8-bit H.264, but I'd say this is a better choice than MTS.
  6. Mark. I need 6 hour recording without big pauses with very small budget. Shooting ProRes 444 will give me only small fragments and tons of additional equipment to keep these fragments and make pauses. And setup price will be x50. It is not a cinema studio. I record realtime actions. Many users shot a similar way, even with cheap cameras, not V-DSLR.
  7. Andrew,

    Is there a tutorial on how to use this software? I'm just not familiar with open source programs.

  8. Eugene ,
    yes. Currently there is one tutorial on YouTube in Russian voice + English subtitles:

    Also, right now I am creating two tutorials on how to use denoisers in free and paid editions. These tutorials will be published tomorrow.
