Avisynth : Rendering .avs to .mov

[DayDreamer3d]

Hi, I am creating a video through AviSynth(works like a charm) using multiple input videos.Noe, I want to render it out as MOV file.


Is rendering to MOV is supprted in Avisynth?
Havn't had any luck finding the solution.


If this doesn't work what are the other options to get MOV out of AviSynth


Thanks In Advance

Avisynth does not render ANYTHING.

What did you actually use to create the video ?

What variant of MOV do you want to create. Quicktime, HD etc.

What software do you use to create MOVs ?

[jagabo]

As noted, AviSynth doesn't "render" to files. You use an encoder or editor to create video files from an AviSynth script. You can use any editor that supports AviSynth scripts as input. I never make MOV files so I don't know what editors/encoder support that as output.

[DayDreamer3d]

I need the MOVs with codec Avid DNxHD.

Guys suggest some editors/encoder that support .avs

[sanlyn]

Again, please note: ".avs" is a text file. It's not a video format. Avisynth's output is unencoded, uncompressed video. You have to feed that output into an encoding app that accepts that output. Some encoding apps can read an .avs script and take its output, some can't. Almost any NLE such as Vegas or Premiere will accept an AVI video output by Avisynth (but they can't always accept the .avs script as input). Try AVS2DVD (which doesn't output MOV) or some of the freebies mentioned in the Tools section of this forum. They are listed with detailed specs and user reviews. If you have some kind of QuickTime encoder installed in your system, even VirtualDub can understand the output of an .avs script and feed that output to some kind of MOV codec. I don't understand why MOV is the priority anyway, but MOV is a container that can be encoded in many ways using many different encoders.

If you have an encoder app that wouldn't know an .avs script from a toaster oven, then you have to save your Avisynth to an AVI video file, then open that file with your encoder.

[jagabo]

As many editors don't support AVS scripts, you may find it easier to use a program like VirtualDub open the script and output uncompressed or losslessly compressed AVI. Then use another program to convert AVI to MOV.

There's an external plugin called QTInput. Part of it is QTOutput which allows you to export movs from Avisynth. You will need to have the DNxHD codecs installed on your system, they are free from Avid, and you will almost certainly need Quicktime Player installed on your system, possibly Quicktime Pro ($29)

Mpegstreamclip may be another option depending on what exactly you're doing. Again you will need the DNxHD (free) quicktime codecs.

[poisondeathray]

ffmpeg accepts avs scripts (if complied with avs support), and can encode to prores, dnxhd (10bit and 8bit varieties, but avisynth is 8bit anyway) without dnxhd or quicktime install

Thanks guys for the answers.As I am new to Avisynth, i really appreciate all the solutions provided, as it helps me to understand the AviSynth better, which I feel is super cool tool.


I will try with QTOutput and FFMPEG.

I tried QTOutput option.It works just fine, but there is one issue.When I apply AddBorders filter on the MOV and then take the output, the output is distorted.
I feel is the issue of the colorspace.


Input Mov properties are:
> codec: Apple Photo jpeg
> colorspace : yuvj420p


Am I missing something ??


Thanks in advance

[jagabo]

What do you mean by "distorted"? Try keeping the dimensions even values. Or even better, integer multiples of 8, or 16.

[poisondeathray]

Are you still using DNxHD ?

You should be aware that DNxHD only supports certain specific resolutions - so when you use AddBorders and other manipulations in your script what is the final resolution ?

[DayDreamer3d]

@ jagabo ... correct ... i was doing with value 2, i changed it to 4 .. it worked perfectly.@ poisondeathray ... thnx for the reply.. final resolution is 1920 × 1080(HD or FHD).


I small query, if I need to cut the border(say. to only 2 pixel)
is first AddBorders() of 4 pixel and then crop the video to 2 pixel.


is this the right way to do it.


Thanks

[DayDreamer3d]

You guys must be tired of my questions but please bear with me, i need them answered.
Issue with audio encoding.


After combining audio and video, audio plays in player but when I tries to render (encode) it, i don't get the audio channel at all in output MOV.


Sample Code:

WAVSource("audio.wav")
AudioDub(video, audio)


# QtSource.dll plugin is loaded
QtOutput('test.mov')


No audio in final MOV. I have to on the audio channel while encoding ?




Thanks In Advance

I don't understand the question.

When the movie settings dialogue box pops up you have to tick video and sound. With DNxHD choose 48kHz, 16 bit, 2ch

[DayDreamer3d]

@ smrpix : There is NO Audio Option in the Compressed Settings Window.



@ jagabo :


I need to have a border of 3 pixel in height.


So,


1. I will AddBorders() at bottom of 4 pixel (as 1 it won't interpolate correctly).
2. I will Crop() the video from bottom of 3 pixel.
3. Resulting Video will contain Border at bottom of 1 pixel.


Is this method right to get borders which are not directly possible.

[smrpix]

You don't get this popup when using QTOutput?

[DayDreamer3d]

Nope.... no at all
I directly get the compression settings.
and I can't use DirectShowSource as my input is a MOV so I have to use QtInput.

Code:mov = QTInput("test.mov", audio=false)
wav = WavSource("wav_it.wav")
AudioDub(mov, wav)
QtOutput('test_audio.mov')


It plays the audio file, but doesn't encode it into output MOV, not getting the Above Window.

Which version of AviSynth you are using and the QTSource.dll
Mine AviSynth is 2.6



Any Help ?

No. YV12 video must be mod 2. You can't crop or addborders to an odd size. If it's interlaced the height must be mod 4. You could convert to YUY2 or RGB to get odd heights but many encoders requires mod 2.

[DayDreamer3d]

@ jagabo ...thnks .. i will check...

currently .. I am stuck with the audio stuff.

[jagabo]

Note that YUY2 will allow odd heights but the width must be even. And no, you can't convert to YUY2 or RGB, create an odd size, then convert back to YV12.

[smrpix]

and I can't use DirectShowSource as my input is a MOV so I have to use QtInput.

Ignore that part, are you not getting the Movie Settings popup when you run your avs script?

[DayDreamer3d]

Tried with different QtInputs and Audio Sources. Still the same.

It Plays the Audio but no option in the Window for Audio

edit: cross posted


So how are you setting your video codec to DNxHD? Some screenshots may be helpful at this point.

Edit: Stop changing your posts so much. I keep answering questions you delete.

[jagabo]

There is one way you can add a ~1 pixel border. Add a 2 pixel border then crop using one of the resize filters. For example, with a 720x480 frame:

# 720x480 YV12 video
AddBorders(0,0,0,2)
BicubicResize(720,480,0,0,-0,-1)

The frame size is still even but there will be a 1 pixel high black border at the bottom. Since the original 480 line image is resized to 479 lines there will be some quality loss.

[poisondeathray]

In order to get that window above, I think you need quicktime pro

[DayDreamer3d]

Sorry for editing the posts.


Settings Values are smillar to the image attached.

In order to get to that screen, you should have to go through this one:

I thought that may be the case, but it turns out it works with a standard installation as well.


Edit: Waitaminute! Daydreamer, Your screenshot is from a mac. How are you using avisynth?

[DayDreamer3d]

@ poisondeathray .... no I tried with quicktime pro too.

actually its about the QtSource.dll
