  • VoukoderPro - Free for all?

    The CCFS CuminCode FrameServer schmuck is happy to charge for his crap programming skills and lousy work ethic. Voukoder works several times faster, and is so much easier to use. Voukoder has no equal that I'm aware of. And believe me, I've looked! Especially if multiple streams and filters will soon be supported . . . Your program is vastly better and worth AT LEAST what he's charging ($15). Possibly 2-3+ times as much.

    Keeping in mind that most of us paid for the NLE suites that we use Voukoder on.

    One thing I would add is that a trial period of 1 week is NOT long enough. That's what CCFS is currently doing, and it did not make me happy. I've got other things in my life that need attention too, and I can't take a week off just to learn a new program. In my experience as a consumer, 1 month is a comfortable time period to figure out if a program will actually do what you need. I needed a couple solid weeks of working with TMPGEnc before deciding to buy it.

    P.S., I decided not to buy CCFS. Total garbage.

  • Rendering for BluRay

    Zitat von dxdy

    I couldn't find a setting for CABAC

    Then I'm guessing your particular GPU only does CABAC encoding.

    Just did a test because I was curious, and it seems that TAW will also accept CAVLC encoding.

    What was probably messing you up last time is the Group-of-Pictures max size (GOP). Most encoders have a really large value by default, mine is 300. For Blu-ray though, this number has to be manually limited to 48 or less (for 24p video).

    Just to clarify, feel free to experiment with the other settings, as you can tweak your picture quality and encode speed quite a bit. @avwtp's settings will probably give you a much better picture than mine. But the settings that are absolutely critical to Blu-ray compatibility are listed in my last post.

  • Rendering for BluRay


    Tried everything I could think of, finally gave up on Architect Pro 6.0 compatibility, switched to TAW (TMPGEnc Authoring Works 6). If TAW isn't happy about something, it'll at least tell you why. Plus if you want to create a DVD from the same project, TAW has hardware MPEG-2 transcoding built in, so it's very easy to make a DVD from an existing Blu-ray project. Have had good success with hardware-encoded files (Voukoder + NVENC) being accepted by TAW without needing re-encoding.

    You don't need all of @avwtp's bells and whistles above to get Blu-ray compatibility. The main things are:

    • h.264 format
    • Blu-ray Compatibility enabled
    • Max GOP size (aka, "keyframe interval"): max 48 (for 23.976/24p video), or max 60 (for 29.97/30p video)
    • CABAC encoding
    • Level 4.0 (technically, 4.1 is allowed by the Blu-ray spec, but I find TAW won't accept Level 4.1 video)
    • resolution/framerate within Blu-ray specs (see the Wikipedia page https://en.wikipedia.org/wiki/Blu-ray)
    • YUV420P color format
    • B frames as references disabled

    Other than the settings listed above, the rest is just playing with encoder settings to get your desired picture quality or render speed. You should be able to leave everything else at default and still get TAW-compatible renders. If you screw anything up, TAW will usually tell you what you did wrong.

    The attached photo is a very barebones configuration that should be TMPGEnc / Blu-ray compatible. (UPDATE: also need to disable option "Use B frames as references". See note below.) The bitrate is really low, so you'll probably want to raise that (this project involved putting 19 hrs of video onto a single disc).


    UPDATE (Aug 2024): When using newer versions of FFmpeg, the option to "use B frames as reference" also needs to be manually disabled for Blu-ray compatible renders. Otherwise, TAW will insist on re-encoding the file, even though it won't report any issues with compatibility. (In older versions of FFmpeg, this option was off by default. In newer versions, this option is enabled by default.)

  • Multiple FFmpeg output streams from single render

    Zitat von iAvoe

    Yep, that's why I suggest you to export first, and then encode into different formats

    You suggest that I export 19 hrs of uncompressed 1080p video . . . okay, let's run some numbers, shall we?

    Ignoring the PCM audio stream, at 100MiB/s uncompressed video-only data rate, that's around 6.2 TiB of data. A SUSTAINED write speed of 1.4 GiB/s would be needed to store the data fast enough (more on that in a minute). That's a respectable hard drive!

    As is, let's take a 7-hr block of video for example (a pair of 3.5 hr videos). I currently run 4 instances of Vegas in parallel (dual-CPU system). Each instance of Vegas is running Voukoder and hardware-encoding the output. The first 2 Vegas instances are encoding the first 3.5 hr video to 2 different formats, and the second 2 Vegas instances are encoding the second 3.5 hr video to 2 different formats. This all completes in 1h55m.

    A tandem-encode function in Voukoder would drop the render/encode time to about 1 hr. GPU hardware is not an issue; I would throw a second card at it, which would more than keep up. Vegas would have literally half the work to do: 2 renders instead of 4.

    So this 'ideal' 1 hr render/encode time is what we're trying to match by using your 'suggestion of exporting first, then encoding'.

    To do this 1 hr render/encode in the way you've suggested, let's say we spend 30 min rendering our master file (2.4 TiB written at 1.4 GiB/s on our amazing hard drive), and then we spend another 30 min encoding. Total time 1 hr. Except that Vegas would take 1 hr just to render the master file. And Vegas is not currently using any compression (it's just firing the raw frames to Voukoder), so Vegas render times are as fast as possible already.

    But maybe you could reduce the impact of the data size by adding some lightweight fast compression, right? Explain to me how you would manage to double Vegas' render speed . . . while adding file compression. Even if you used a compression format that Voukoder offers, you still would need to DOUBLE Vegas' render speed to make your idea work. As mentioned, Vegas is rendering as fast as possible already.

    All that . . . just to match what a tandem encode function in Voukoder could do.

    Yep.

  • Rendering for BluRay

    In the Preset dropdown, I don't have a Bluray option. Just 7 speed options from Slowest to Fastest. Tried rendering using the other NVENC settings as shown, and Architect Pro doesn't even recognize the resulting file as a valid video file . . . although it'll read the audio track.

    GPU is 2080Ti, Compute Capability 7.5, Voukoder 12.1, Vegas Pro 15, Architect Pro 6.0.

    Looking for a way to get Blu-Ray AVC/MP4 output that's compatible with Architect Pro without re-encoding.

  • Multiple FFmpeg output streams from single render

    PlasmPlayer and iAvoe:

    The problem is that Vegas itself takes a lot of horsepower to render the raw frames, and this is needlessly duplicated if I need to have the same render encoded as 3-4 different formats. Vegas renders the raw frame, then encodes it to whatever format you specify.

    No point in Vegas rendering the identical raw frame 3-4 times, which is what a batch render or script would do. This is extremely inefficient in a big render/encode op that takes many hours.

  • Multiple FFmpeg output streams from single render

    Need to render the same project in Vegas Pro into multiple output formats (h.265, h.264, MPEG2 DVD, AVC Bluray, AC-3 audio). Biggest bottleneck is Vegas' rendering itself, not the encoding. Any way to allow Vegas to render to a single high-quality stream, and encode that single stream simultaneously into multiple formats using Voukoder?

    Hardware is not a limitation here, but Vegas is. Duplicating the rendering workload seems completely pointless to me.
