Virtualdub External Encoder feature.

[BUDA20]

Thanks! it just worked (by default it uses h264)

Just added the codec I want and some quality options just to be sure

NVEncC and HEVC:
--codec hevc --mv-precision Q-pel --profile high --raw --input-res %(width)x%(height) --fps %(fpsnum)/%(fpsden) -i - -o "%(tempvideofile)"

Thanks again.

I don't understand two basic things.

1. With External Encoder, is it possible to just copy audio+video using FFMPEG and remux to MKV using MKVMerge?
If yes, how is it done?
2. In what directory/folder are tempvideofile/tempaudiofile being created? How to change this path?

[DarrellS]

Hi, I been trying without success to adapt NVEncC as an external encoder for VirtualDub.

NVEncC is used by StaxRip to encode HEVC and H264 using nvidia GPUs
(I think is using a pipe from AVS)

Maybe someone with more experience than I can figure out how to do it.

thanks in advance.

I can't answer this for the newer NVidia cards since my PC and my older card does not support encoding but for older cards there is encoding using cuda.exe.

Here is a working encoder set. Copy text and save as Cuda.prof.

EDIT: You need to get the Cuda.exe encoder from Selur's Hybrid program.

You can do ac3 passthrough and mp3 passthrough with ffmpeg but you cannot do video pass through or any other audio formats AFAIK.

"mp3pass": {
"name": "mp3pass",
"program": "ffmpeg.exe",
"commandArguments": "-i - -acodec copy \"%(tempaudiofile)\"",
"outputFilename": "%(outputname).mp3",
"type": 1,
"inputFormat": 0,
"checkReturnCode": true,
"logStdout": true,
"logStderr": true,
"bypassCompression": false
},
"ac3pass": {
"name": "ac3pass",
"program": "ffmpeg.exe",
"commandArguments": "-i - -acodec copy \"%(tempaudiofile)\"",
"outputFilename": "%(outputname).ac3",
"type": 1,
"inputFormat": 0,
"checkReturnCode": true,
"logStdout": true,
"logStderr": true,
"bypassCompression": false
},


The temporary path is wherever you decide to save the finished file. Watch while it is encoding and you'll see the separate files being created and disappear when the muxing is finished.

[shekh]

Anyone has any idea why the final image through External x264 has slight colorshift compare to the same clip processed through x264vfw with the same settings? The latter matches original, but the first one does not.

Not sure if this is a common knowledge but as I discover this will try to explain now:

External encoder interface has a not so obvious conversion to limited range 601 colorspace.

This can produce all kinds of disaster unless you put two filters at the end of your filter list:
1) convert format to yuv 709 FR - since your encoder is setup to treat rawvideo as this (if I understand correctly)
2) alias format to yuv 601 - to bypass further conversion

[sneaker]

If you just input an AviSynth script VirtualDub will treat it as BT.601 IIRC, i.e. you often don't need to change anything. So be careful about using a conversion filter to 709 - we usually don't want any conversion at all.

[shekh]

I saw "Matrix coefficients : BT.709" in the quoted message so if that was intentional he had to have either 709 source anyway or RGB source converted to 709, I guess.

[shekh]

If by chance somebody finds useful to export RGB, YUV 4:4:4 etc

[movmasty]

Any update for the HEVC(x265/Divx265) encoder?

I know that x265 had heavy development in the last 16 months

[sneaker]

1. If you want to update x265, just download a new x265.exe (e.g. from here, more alternatives here)
2. You don't need any updated VirtualDub profile because
a.) the basic commands (input/output/crf) have not changed
b.) the x265 team changes the defaults/presets from time to time to give you the benefits of new developments without having investigate yourself

[movmasty]

Thanks, this i wanted to know

Silly, i believed that racer-x posted all the programs nice tutorial

[Tafflad]

Want to give this a go ... could be what I need .....
I have 32 bit VD installed .... (64bit OS) do I need to match it with 32 bit x264 codec or as this is exporting out of VD can I run the 64bit codec ?

[sneaker]

You can mix vdub 32 with x264 64 bit.

[xuxo]

@ racer-x
The animated gif is output ok along with a zero byte file - same name as the gif but no extension.
Any ideas?

You can just delete the zero byte no extension file. It is just a temporary file. I haven't figured out how to auto delete that one yet.

try
at Edit External Encoder Set Tab
1.check Process partial when render is aborted
2.File extension gif
3.check Replace temp video/audio with path

at Edit External Encoder Profile Tab
1.Output filename change to %(outputbasename).gif
2.check Delete output file before starting

Thanks so much for these guides, a real education and I finally have Virtualdub working like I had always wanted it to....
regard; vic

[godai]

hi i have trouble making work [aac fdk] fdkaac of pack profiles of DarrellS

i have this on it

-bitrate-mode 0 -o "%(tempaudiofile)" --raw

im getting anonymous pipe , the pipe is being closed.

[sneaker]

You need to specify input file ( "-" for stdin) and channel config for raw input. I'd use wav input instead (tick the WAV output box in VirtualDub encoder config):
-o "%(tempaudiofile)" -

[godai]

i still getting same error with
yours.
-o "%(tempaudiofile)" -
also i tick wav output box.''

thing too its im not very good with commandline, so thats why ask help here, thank you anyway.

[sneaker]

thing too its im not very good with commandline

That makes it a bit difficult to help. My next question would have been if your build worked correctly and if you can run fdkaac.exe from the command?
It's not really clear what is causing this for me. Maybe the VirtualDub log (F8) can give us better hints.

[godai]

anything else its working fine, i just try to run some new ones that i get here.

i able to run fhgaacenc.exe [one build with winamp files]

--vbr 1 --ignorelength - "%(tempaudiofile)"


fdkaac.exe, it was build with special instructions [zip file , master build...zip] for what i read i only need ,.exe file. [fdkaac.exe]
i dont know what i did wrong but i copy paste your commandline and throw me a 000000...1 , so it run but gives error, it just was one time after i getting same results.

anonymous pipe , the pipe is being closed.

i will keep trying if i find some error

thank you again

[raffriff42]

If I am reading the fdkaac docs correctly,
[options...] - -o "%(tempaudiofile)"
might work, i.e. putting input before output.

[godai]

ok , i find something.
i try with two different kind of files, both recorded of atsc, one 1080 and one 720

with 1080 one i get this error.
The audio encoding process has prematurely 0000.....1 error code

second one i get pipe is being closed..... using other audio encoder i can process file.

[raffriff42]

These kinds of errors are due to a previous, invisible error, which you should see listed in the Log (View menu, Log)
Scroll to the end, then page up until you see the first irregularity.
If you can't figure it out yourself, right-click in the Log window, click "copy to clipboard", and paste it in your reply.

[godai]

ok i attach it,

[raffriff42]

The log is not as helpful as I had hoped it would be.

...
[*] Beginning dub operation.

[i] Dub: Input (decompression) format is: YUV420.

[i] Dub: Output (compression) format is: YUV420.

[E] Error: Write error occurred on file "<anonymous pipe>": The pipe is being closed.

There has got to be a syntax error in one of your encoder settings. Note, this might be on the video side.

Can you get DarrellS's profile to work without changes (except for .exe path) ?

Could you please post a link to where you found this profile?


EDIT your log started with a different error, which I assume you fixed. It might be helpful as an example of what I was talking about before.
If you didn't fix it, well, there's your problem!

[*] Beginning dub operation.

[i] Dub: Input (decompression) format is: YUV420.

[i] Dub: Output (compression) format is: YUV420.

[i] AudioEnc: bitrate or bitrate-mode is mandatory

[E] Error: The audio encoding process has prematurely exited with an error
code of 1 (00000001). Check the log for possible error messages.
[*] Ending operation.

[sneaker]

You can set "Redirect standard output to log" and/or "Redirect standard error to log" in the encoder settings. Then more info might show up in the log.

[raffriff42]

Right, I assume DarrellS's profiles are already set that way - at least his later ones.

[godai]

audio setting encoder

- -o "%(tempaudiofile)"
%(outputname).m4a

, i mark all 4 options in the encoder, default one , comes in that way.

video encoder x265
--crf 24 --preset medium --input-res %(width)x%(height) --fps %(fps) -o "%(tempvideofile)" -
%(outputname).hevc


i have installed , mp3, acc nero, and fhgaacen , they are working fine.

profiles i take it of here , first pages, sorry i not time to bring it now here, tomorrow i do it.

full log with 4 marks,

i delete first messages in log , but this time i leave it, there its errors with plugins of virtualdub, but despite that i able to finish jobs with other external encoders.

[raffriff42]

Thanks for the links and the pasted code. I don't see '-' (stdin) anywhere; I thought it would be required.

There are at least two fdk-aac programs on GitHub [here and here]. There may be others. The command line syntax may vary, I don't know, and I don't know which version DarrellS wrote his profile for. Try to run your fdkaac.exe in a command window with the '-h' (or maybe '-help') option to learn the proper syntax and figure out what you need to change.

EDIT bypassCompression=false and --raw don't seem to belong together either.
