  • Davinci Resolve now allows for third party render

    Zitat von Schnubbi

    I'm getting around half the speed from Resolve's Nvidia Encoding.


    Resolve 1440p 60fps: ~240fps while encoding (4:01 for a 15min Vid)

    Voukoder 1440 60fps with h264 nvidia preset: ~114fps while encoding (7:56 for a 15min Vid)

    Well, this is just a first prototype of 2 days work. Nothing has been optimized yet. But I don't think voukoder will ever be faster than the native DVR implementation. The goal is to have more encoders available in DVR - the existing encoder implementations seem to be quite good actually.

    Currently the plugin gets the video as 422 and voukoder needs to convert it down to 420. That's something I can still optimize and it should give some more speed.

    You have an active filter btw (gamma correction). Removing it gave me 40 more fps.

    It runs stable, but I have to restart Resolve after using Voukoder, because the normal encoder wouldn't work anymore.

    Looking into that.

    Edit: This seems to be working after todays DVR update (17.1.1 Build 9)

    My GPU also only gets 50% Usage while enconding with Voukoder. Maybe I did something wrong here? Normal Resolve encoding uses around 99% GPU.

    If you set the preset to "slow" it uses 100% GPU.

    Still: Voukoder is not the magical tool to make everything faster. But it might offer you more encoders and more options. And I guess DVR uses CUDA in a clever way to prevent lots of copy actions from/to host and gpu.

    Here is the first prototype to test. Please tell about your findings / issues here in this thread. (You need to have Voukoder installed, of course).

    Extract the ZIP file here and start Resolve.

    The plugin will appear here:

    Please note: If you like it and if you want to have further support and development consider donating. It will really help me, thanks.

    P.S.: It will only work with the studio version of DVR. The plugin does not work with the free version.

    Edit: You can find the latest version in the regular voukoder download section now.

  • Davinci Resolve now allows for third party render

    I'll have to find some time to investigate this in detail, but ...

    An encoder encodes exactly one uncompressed stream to a compressed stream. (That's what Mainconcept might do). i.e. uncompressed 4:2:0 to compressed h264.

    It then returns the data back to DVR so it can package it in whatever container it wants. (i.e. MP4 or MOV)

    The big question I need to find out is if DVR also supports an external muxer. So i can get both video and audio (in sync) from DVR, send both to Voukoder and Voukoder handles muxing and outputting.

    But from what I've read is that this SDK is an encoder SDK only. It is not a generic File I/O SDK, which I have for Premiere, AfterEffects and VEGAS.

  • Feature Request: HW Accelerated Filters

    Zitat von Samwise Gamgee

    I believe that the difficulty with Premiere/Vegas/etc. will be getting the frame to decode at all on the GPU more than anything else, but I could be wrong

    This is out of my control. At the beginning of it all I get a pointer to a frame buffer in the CPU addressable memory. So the NLE is doing all decoding, rendering, etc.

    Some months ago I was investigating if CUDA could improve the speed of pixel format conversion in the high bit depth mode. I noticed coping frames back and forth between CPU and GPU memory is quite expensive and I should do it as less as possible.

    I guess the "cuda" pixel format in FFmpeg contains a pointer to the GPU memory. So I guess with the FFmpeg command line above you're doing exactly what is was talking about as "way 2".

    As I am using FFmpeg/libav on the C API level, I still have to figure it all out. But this will be included in voukoder sooner or later.

  • Feature Request: HW Accelerated Filters

    Yes, I see your point on this. I plan to add this to the voukoder successor actually and I would like to implement this in a smart way.

    From what I understand is how the would work in the current voukoder:

    1. Copy frame from CPU to GPU
    2. Apply CUDA filter
    3. Copy frame from GPU to CPU
    4. Copy frame from CPU to GPU
    5. Do GPU encoding
    6. Copy frame from GPU to CPU
    7. Write to disk
    8. Go to step 1

    I'd love to do it in this way:

    1. Copy multiple frames from CPU to GPU (as many as fit in the GPUs memory)
    2. Run CUDA filters over all frames
    3. Du GPU encoding on all frames
    4. Copy frame from GPU to CPU
    5. Write to disk
    6. Go to step 1

    I'm trying to find out if the FFmpeg accelerated filters work like the first way to the second way. Do you have any info on this?

  • Voukoder 8

    Thank you for your most intelligent post to this forum.

    1. When people ask for a download possibility directly from the creator where they can easily download the original file(s) they need I'm willing to help them, yes. I'm not the kind of person to tell them "You want it? Search for it! HAHAHA! LMAO"
    2. People have asked me how they can support and donate to this project, but the current options won't work in their country. So I am thinking of providing possibilities that allow people from this country to support to this project and try to set up services like AliPay, etc.
    3. And why should I ignore requests from people if they represent the largest group of voukoder users?

    P.S.: You might have noticed this is not just related to one forum post.

  • Dropping support for Adobe Premiere CS6?

    I know there are quite alot users working still with Premiere CS6. Maybe because of the faster and more responsive UI, maybe because it doesn't require a subscription model to use it. Unfortunately Adobe removed all downloads completely a while ago and there is no way of installing it anymore as an "old version" from the creative cloud app. Adobe also rejected my request to provide me an alternative solution to somehow still get CS6.

    That basically means I also have to drop supporting CS6 in the Adobe Premiere Connector, too.

    But maybe there is one last chance: If the CS6 community would be able to donate me a (fully legal) Premiere CS6 package I would be able to continue testing to make sure later versions of Voukoder are still compatible with it. Illegal ways to solve this matter are not an option!

    Thanks.

    Release Notes

    Make sure you are using the latest connector for your application(s). For using NVENC (SDK 9.1) encoders driver version 436.15 or later is required.

    Chinese users

    As Voukoder is very popular in china I'd love to make it more (easy) available for chinese users. I need a chinese contact person that helps me to understand the chinese situation better and support me with setting up various services in china that I can also access from europe. Please contact me if you have experience with this, you can speak good english (or german) and want to help. Thanks.

    Fixes / Changes

    • Fixed bug where the video is just a smaller video cropped out of the original frame size
    • Fixed audio frame size inconsistency bug
    • Added Opus and Vorbis support to MP4 format
    • Adding timecode information for MOV and MP4 formats (TIM, TSC and TSZ)
    • Added RGBA pixel formats (8 and 16 bit) to the FFV1 encoder
    • Updated FFmpeg core.
