So when I export like this ...

.. I get:

Audio

which should be okay, right?

Added connector for After Effects:

https://github.com/Vouk/voukoder-connectors

Please run "regedit" and confirm that this entry ...

Computer\HKEY_CLASSES_ROOT\CLSID\{E9661BFA-4B8E-4217-BCD8-24074D75000B}\InprocServer32

... looks like this:

And make sure voukoder.dll is available at that location / folder.

did you also install the latest voukoder 2.3beta4 version?

Released 2.3beta4

Changes:

• Optimized COM interface based on MIDL (not backwards compatible)
• Added "Equalizer" video filter
• Added FFmpeg logging to STDOUT

Attention:

This is not compatible with the previous 2.3beta3 Voukoder and connectors. Please uninstall these packages first and then install the 2.3beta4 version.

It might also be required to delete all presets / templates from a previous version for it to work properly.

Normally this selection should be taken from the projects settings. Can you please try changing it in the projects settings.

For me these are two separate topics:

1. A bug / known deficiency in Vegas Pro

2. An additional filter in Voukoder (for whatever purpose)

First, FFmpegs Equalizer / eq filter will be available in the next version to adjust brightness, contrast saturation and gamma (even per color channel). https://ffmpeg.org/ffmpeg-filters.html#eq

Second, Magix has confirmed the vegas preview shows full color range only. So if your source file is based on the limited color range (which is the case for 99% of all YUV 4:2:0 8 bit files) it will appear brighter than it actually is (in the preview). This does not affect the rendering process itself, so your rendered file appears darker than the preview (but still matches the original clips brightness / colors).

There is no connector for after effects yet. You could only export through media encoder until the AEX is finished.

I am discussing this issue with Magix at the moment. Getting it fixed would be best of course.

And yes, filter will come. It's not on priority 1 though.

Zitat von serpin

I wouldn't remove the values, rather change the labels to:

Well, with FFV1 you could also export with 12 or even 16 bit and you'd have different values (in theory).

Actually this doesn't seems to be Voukoder issue (or generally not an encoder issue) but more like how certain decoders are interpreting the encoded file.

So users should not change this setting unless they really know what they are doing.

Kannst du noch eine Voukoder Log Datei anhängen nachdem der Fehler aufgetreten ist?

Hast du zwischendurch ggf. etwas anderes verändert? z.b. die Premiere Version geupdated, o.ä.?

The color range selection is always present. It does not change or disappear for certain encoders.

There is always a possibility for "headroom" and "footroom" in a limited color range. It is just labeled like this for 8-bit resolution.

For 8-bit the range is: 0-255 (16-235)

For 10-bit the range is 0-1023 (64-940)

Actually I could remove these values to avoid confusion about it.

I have to admit I am not sure what it means for "ProRes". It is just a necessary technical requirement and I just allow the user to change this setting. And yes, it was absolutely intentional to set the value to limited by default.

That is correct. But there is also an (inofficial) patch available.

Proposal for a solution for CC2017

I mean, I don't have the Movie Studio software, so I can't test.

According to Wikipedia Movie Studio is a stripped down version of Vegas Pro. Unfortunately i can not test it. I only got a license for Vegas Pro.

Okay, ich kann es nachstellen und untersuchen.

My mistake. It does not expand it, it just displays it.

What I meant: the preview just displays what is in the framebuffer.

If you load a limited frame into it where 0x10 is supposed to be black it will display it as dark grey. The preview simply ignores any color range setting.

In the projects "Pixel format" setting dropdown box there should be actually:

8 bit (Full)

8 bit (Limited)

@MajorBubble

Right, most YUV 8 bit content is supposed to be limited. The internal preview expands it to full (black = 0x101010, white = 0xebebeb) and that's what it makes look brighter.

People apply a brightness correction to make it look like the original again, render it and the external player shows it darker - Which is correct.

And I even know the technical reason for this issue: The preview is a direct pointer to the uncompressed framebuffer. (I once vertically flipped the framebuffer and the preview flipped too).

Still this is a very, very bad design as most 8 bit video is actually limited.

I tend to agree. But to me it looks like the preview is actually too bright.

If i compare the source video and the exported file brightness/contrast/gamma look identical to me. But the preview just looks to bright.
