VirtualDub2

[LigH]

Oops, my fault, I only thought about the ffmpeg command line interface... :o

MeGUI uses the x265.exe command line encoder; this is neither a VfW codec nor a library module (as used in VirtualDub2's separate "FFMPEG / x265" encoder).

You might use the x265 CLI encoder via the "External encoder" setup in VirtualDub2. But this has no pretty user interface.

[poisondeathray]

I installed x265vfw v3.40 which like libx264 core 157 video encoder does offer a method of entering 'Sample Aspect Ratio' values. But sadly the entered values don't appear to make it into the video stream :(

https://i.ibb.co/vjTs1zf/x265.png

By contrast, the x265 video encoder in MeGUI is able to produce encodes with aspect ratio signalling within the video stream. But I don't know when/where this SAR information is added


Your screenshot for x265vfw shows DAR width, height, not SAR . Try 16 and 9 .

If the the extra commandline box works, you can enter --sar x:y there instead

[SeeMoreDigital]

Your screenshot for x265vfw shows DAR width, height, not SAR . Try 16 and 9 .After entering '16' in the 'DAR width' box and '9' in the 'DAR height' box, I can confirm that no aspect ratio signalling makes its way into the video stream...

[LigH]

Does it work differently if you use a side channel "Output file" in x265vfw, instead of passing it through VirtualDub2?

[takla]

Is there any way to get 10bit to the dropdown menu under external encoder settings? I can only pick between yuv 8bit, 16bit and various rgb pixel formats.

Such option is not implemented, but I assume it is safe to roundtrip 10-bit content in 16-bit. Are you afraid of rounding error?

[takla]

I wanted to encode in 10bit (lossy) for better precision from the encoder. I'd like to do this with vdub2 since it is nice for cutting the video frame accurately. I'd then send the stream to ffmpeg.

Not sure what you mean with "roundtrip 10-bit content in 16-bit". But when I select 16bit, and set 10bit as an ffmpeg command, I get the following 2 errors:

with -pix_fmt yuv420p10le and 4:2:0 8bit yuv

the ffmpeg command line must include pix_fmt twice: one for raw input and another for your desired output

like this:
-f rawvideo -pix_fmt %(pix_fmt) -s %(width)x%(height) -r %(fpsnum)/%(fpsden) -i - -c:v libx264 -pix_fmt yuv420p10le %(tempvideofile)

%(pix_fmt) macro always matches the format selected in dropdown in ffmpeg syntax.

Ohh I see. Thanks. It's working now.

[GAP]

I have two questions:


What is the difference the x264 8 bit and x264 10 bit codecs respectively? And is it similar to x264vfw codec?
Can anyone explain what those FFMPEG encoders are?

[LigH]

1. x264 8 bit encodes video in the MPEG-4 AVC Main/High Profile with internal quantized components of 8 bit resolution; x264 10 bit encodes video in the MPEG-4 AVC High 10 Profile with internal quantized components of 10 bit resolution. The latter is specifically known to be useful for cartoon video content. — NOTE: Not every player is capable of playing High 10 Profile AVC video.

2. They are not VfW codecs, but provided by a separate collection of encoders based on ffmpeg's libavcodec library, so they are independent of any codecs installed into your Windows system. Similar to the decoders in VLC. VDub2 contains ffmpeg based decoders, too

[LigH]

I got a report that VirtualDub2 doesn't handle audio conversions when processing a clip with 24 bit PCM audio. Using FFmpeg Lame MP3 produces loud static noise (I can confirm). FFmpeg AAC "crashes" (in my case the dub process gets stuck after 650 audio samples, then "Integer division by zero" crash).

When I try to convert the audio to 16 bit internally in VirtualDub2 before compression, it fails with an error message in the Audio group of the "Save video" dialog, Sample Layout: [Cannot convert audio: the source audio form{...}].

[LigH]

Any idea about the reason, shekh? 24 bit integer not supported in the audio pipeline?

And again, the ffmpeg library ages on and on...

[richardpl]

What ages on and on?

[LigH]

VirtualDub2 still uses an ffmpeg plugin version with an older API because adapting VirtualDub2 to the requirements of the most recent ffmpeg API version seems to be a heavy challenge for shekh...

[shekh]

Any idea about the reason, shekh? 24 bit integer not supported in the audio pipeline?

Sorry for late reply, do you still have the sample? I tried it and it works for me (converted test file to pcm_s24le with ffmpeg).
Anyway, VD2 can internally work with u8, s16le, f32le. Other formats get converted by the input driver.

[Emulgator]

x264 with CRF <17 might be what you're searching for.

[LigH]

@shekh: 24 bit example (https://www.ligh.de/tmp/String1s24b.7z). AviSynth script just as dummy video track. Important part is the WAV file to be used as external audio track (Audio - Audio from other file...), in Audio "Full processing mode" and with a Compressor. Archive contains an MKV with Ut Video and PCM audio track, and to compare, another with MP3 audio track compressed via the FFmpeg Lame MP3 encoder. The result with AAC is broken, did not add this.

Audio driver is an "NVIDIA High Definition Audio" device, general Windows 10 64b.

[GAP]

How do you convert AVISynth scripts to Virtualdub processing scripts?

[LigH]

Not generally possible. They may handle fundamentally different actions (e.g. VirtualDub has no substitute to every possible AviSynth filter and NLE feature, whereas AviSynth is not able to select a codec for the compression).

[StainlessS]

How do you convert AVISynth scripts to Virtualdub processing scripts?
As LigH said, but you can load avisynth scripts into VDub2, and additionally process in some way, and/or add to queued jobs list.

[GAP]

Okay thanks.

[StainlessS]

Yo shekh,
If you do get back to this, can I ask if cursor in AVS script editor be sizeable, specifically adjust width wider,
on 4K monitor and Windows 10 scaling to 150%, cursor is almost invisible in the editor [W10 scaling or Ease of Access cursor width seems to make no difference].
I quite often find myself having to click with the mouse so I can tell where the cursor is.

Thanks muchly :)

[wonkey_monkey]

It seems VirtualDub2 doesn't understand Y-only clips with >8 bits. Not sure if this has been noted before so just putting it on record.

[Wilbert]

I made this one sticky, and collected all the depreciated stuff into one sticky. Let me know if anyone has other suggestions.

[wonkey_monkey]

You could un-sticky my "Compiling VirtualDub with VC++ Express - how I did it" thread because it's hopelessly out of date.

[LigH]

Are you barking at the wrong tree?

[GAP]

Due to circumstances involving my laptop's GPU being busted, I am foced to use my Woindws XP comuter. I wanted to convert my videos to .mp4 but while converting my video, I encountered an error called "Requested frame not found". I am not sure what has caused this error but I want to convert my videos using Virtualdub2. Can anyone help me?

[nji]

With my limited knowledge I would say that
the video stream is defect in some way.
Try different decoder (at VD2's open dialog),
or try avidemux.
If successfull check the audio (sync and quality).

[StainlessS]

"Requested frame not found"

From another of your threads, [EDIT: GAP threads]
If you can't play back uncompressed in realtime, I'd worry that you might not be able to record uncompressed in realtime, and thus would get dropped frames. So double-check that before trying uncompressed.

Recording uncompressed video is a great use case for RAID, if that's an option for you.

From this [GAP] thread,

Maybe suggest trying the batch script with that error producing clip,
BAT(same thread) = https://forum.doom9.org/showthread.php?p=1948505#post1948505

See if ffmpeg gives any further info in error message for the missing frame,
perhaps it can even auto conceal the error. (producing legal output clip)

What version of AVIDemux works with XP?
Last working version: https://sourceforge.net/projects/avidemux/files/avidemux/2.6.20/
Until today (v44282) all virtualDub2 versions work with XP, some third party plugins (as Filtres_JPSDR) may fail.

[isidroco]

What is the the input caching driver? I heard once that it might be somehting wrong with the driver.

In VDUB2, File, Open, at the bottom you can use original VDub Input driver: "Audio/video interleave..." which will only open AVIs (and will fail to accurately seek frames on h264/h265). Or "Caching Input Driver" (FFMPEG based) which will open almost anything although you will loose DirectStreamCopy (unless video is compressed using a compressor with AllKeyFrames as MJPG).

[nji]

?How?

[LigH]

Not in VirtualDub2; it does not contain a fully configurable native HEVC (x265) codec.

[SeeMoreDigital]

HEVC; set display aspect ratio
?How?Not in VirtualDub2; it does not contain a fully configurable native HEVC (x265) codec.Indeed... You'll need to install one of the x265vfw versions if you require access to DAR options ;)

[LigH]

I would recommend configuring a x265.exe as external encoder instead. HEVC does not belong into VfW.

Thankyou for your help!
I'll do as you proposed.

I will have to try that but unless I buy a Windows 10 or above computer, I am still need to figure out how to make mp4s.

Even the XP build version ? :scared:

There is an XP build version?

[jpsdr]

I was talking about the XP build version of my plugins, not VDUB2.

[GAP]

Sorry about that. Anyway I think the only reason Virtualdub2 worked on my computer for a time is due tot he codecs I used. I may need to manipulate the registry or something to "reformat" the program. It seems like Virtualdub2 will only work on Windows 10 or if I used codecs like XVID or something.

Edit: I discovered that I had to change the input driver from :Caching Input Driver" to "Audio/video interleave input driver (internal)" to successfully to convert a video on XP. I also discovered some options on both input drivers but I do not know which is ideal for XP.

Can create your own as above, or download 7z compressed file of about 35MB [including ffmpeg.exe] from UTILITY/Batch_Converter.7z
from StainlessS@MediaFire below this post in my sig. [in the UTILITY folder]

or direct link here:- https://www.mediafire.com/file/nhaxvwpcjphlkn8/BATCH_CONVERTER.7z/file

I think you could point output to anywhere else by replacing BLUE '.\OUTPUT' above with FULL DRIVE & PATH (no filename nor extension EDIT: Output folder MUST Exist)

If you already have path to ffmpeg.exe set in your system environment PATH Variable, then can change above %FFMPEG% to just FFMPEG.EXE and it should work without needing
the FFMPEG\ffmpeg.exe in zip.
eg,

setlocal

FOR /R ".\INPUT" %%A IN (*.wmv *.mpg *.avi *.flv *.mov *.mp4 *.m4v *.RAM *.RM *.mkv *.TS *.ogv *.264 *.webm *.m2v *.VOB) DO (
Ffmpeg.Exe -i "%%A" -vcodec utvideo -acodec pcm_s16le ".\OUTPUT\%%~nA.AVI"

and then dont need the FFMPEG folder or zip included ffmpeg.exe.

I think I might have solved my caching input driver problem. I had to go the Virtualdub2 Sourceforge (https://sourceforge.net/p/vdfiltermod/wiki/Home/)and download the input driver (https://sourceforge.net/projects/vdcachingdriver/) myself. I am not sure if that is the 'right' thing to do as it was for VirtualdubMod but it seems to work for my XP. Other computers that run Windows do not have that problem. Looks like it is solved for now. Thanks for the help.
