  • Vegas Pro: Audio Shift in rendered video

    Could you please have a look at this:

    https://www.dropbox.com/s/9vp35vgfle35…Shift2.zip?dl=1

    In archive:

    - Source m2ts file

    - Simple project where I just dropped single file on timeline and delete all audio tracks but front one

    - Wav file that I rendered from the project

    - Two mp4 files rendered with Voukoder. One without atrim and one with atrim 0.044

    - Comparison project in which I dropped all these files

    =>

    atrim 0.044 audio shifted more ahead. This is predictable as if I understand correctly, atrim stand for Audio TRIM and so it is trimming a bit of audio at start and the rest of audio shifting ahead.

    For the project I need option to shift audio behind.

    Thanks.

  • framerate constant/variable

    I do not know how this is possible unless you specified VFR in Voukoder options.

    VP cannot supply VFR to encoder and framerate specified in project settings is used.

    You should set 60 fps and enable resample in your project settings.

  • Vegas Pro: Audio Shift in rendered video

    Could you advice, how the filter can be used for fix the described issue when audio is ahead of video?

    If I specify Start (in s), the audio will be further ahead. Negative values not accepted.

    Stare/End samples do not work ar all: as soon as I finished enter value it reset to 0.

    P.S. Voukoder 4.1 and Vegas Connector 7.0

  • Important connector updates

    I'd prefer not to have this feature or to have option that I can switch the feature off :(

    I do not like when programs connecting to internet to check for updates and always switching this off if possible.

    Especially I do not like when it happens on startup as it slows program startup and brake normal workflow.

    I bet you have not checked all possible scenario for this. No internet? No/disabled NIC? Firewall? Proxy? Server not available? Certificate expire? Server moved? (No offence. But I've already seen so many bugs in checking for update implementations that I'm almost sure in this).

    So people will deal with many such errors because of the feature.

    I'd like to start Vegas and edit video. May be this time I'm NOT going to do any renders at all (I'm editing video almost every day, but rendering probably once a week). Or may be I will use other encoders this time (lossless, intermediate).

    Imaging that ALL plugins will do this. This would be nightmare as people will deal with all these update messages, but not with what they wanted to do.


    I believe that such feature should be not on startup but in Voukoder template. If no core installed -- error message. And button to check for update when pressed. I know that some other plugins implemented uuto update this way . I do understand if someone provide plugin pack. In this case it makes sense to have async process somewhere that will check is new pack is available instead of injecting it into all pack's plugins.

  • Vegas Pro: Audio Shift in rendered video

    When I render from Vegas Pro 17 with Voukoder/x264/AAC I see that in resulting file audio stream is ahead of video stream.

    If I render simple wav or using internal encoder audio and video are in sync.

    People in Vegas Pro forum mentioned that this is known issue and they have the same issue while rendering through frameserver + handbrake/x264/AAC: audio stream is 44ms ahead.

    Another option for render from Vegas using x264/AAC is Happy Otter Scripts and autor added workaround (ffmpeg option -itsofffset 0.0444) to deal with the issue.

    Is it possible to add option into Vegas connector to add audio offset (defaulted to 44ms) that can be used to deal with the issue?

    Thanks.

  • Denoiser ?

    I think it is a bit strange to have such filters in encoder.

    In my universe, such things should be done in NLE.

    The main purpose of encoder is encode. Adding many things not related to encoding into encoder is making it harder to use (UI becoming more complicated) and possible adding some bugs.

  • x264 AMD-AMF CRF -- resulting bitrate is too high

    I tried to render the same file in Handbrake with x264 CRF23 vs H264 AMD VCE (Quality) CRF23.

    The second file is 4+ times bigger and there are no B-frames in it at all (I was just told that VCE does not make the B-frames while encoding. Did not know that).

    So this is not the Voukoder issue, just ignore the "bug report"

    Thanks.

  • x264 AMD-AMF CRF -- resulting bitrate is too high

    Did simple comparison x264 CPU vs x264 AMD-AMF with similar options.

    From defaults I only changed to CRF=21

    Voukoder x264 CPU rendered test project with bitrate about 20 Mbps. I rendered the project with x264 encoder (through MeGUI) many times and bitrate was about the same.

    However, when I rendered the project using Voukoder x264 AMD-AMF encoder with the same options, the resulting bitrate was about 50+ Mbps that looks a bit too high.

    So I think it might be a few things:

    1. x264 AMF is really produces much worse quality and so for the same CRF encoder uses higher bitrate to meet quality requirements;

    2. Voukoder does not pass or incorrectly pass some settings to x264 AMF and so the high bitrate is used.

    Could you advice, how can I check what is causing the "issue"?

    Thanks.

  • No Audio option

    It would be nice to have 'None' in audio dropdown.

    Right now even if project does not have audio, there is no chance to render file with voukoder without audio stream.

    This can be usable for testing and rendering intermediate files.

    Thanks.
