Using CCE to convert DV to MPEG2 and I need a YV12 Codec

[videocheez]

I'm trying to use CCE to convert some Type1 DV home movies to MPEG2. I finally got my script dialed in..... I think. When I started encoding, CCE stopped and gave an error that said I need a codec to handle yv12. Does anyone know of this codec. Any help would be appreciated.

Thanks in advance,

VC

what is your script. What is your source codec.

Using AviSynth script? Add the line convertToYUY2() then, CCE doesnt support YV12.

Man you guys are fast. I may actually get a chance to start the conversion before I go to bed tonight. This is my script:

AVISource("C:\Documents and Settings\daddy\My Documents\Adobe\Premiere Pro\7.0\Adobe.ds\arrowoflight\gknot\arrowforeditin gna.avi")
ConvertToYV12()
SeparateFields()
odd=SelectOdd.Convolution3D (1, 6, 10, 6, 8, 2.8, 0)
evn=SelectEven.Convolution3D (1, 6, 10, 6, 8, 2.8, 0)
Interleave(evn,odd)
Weave()
DoubleWeave.SelectOdd()
FlipVertical

Whe I first tried this, I didnt have the flip vertical line in there and the movie was upside down.
Instead of the flipvertical line I did have ConverToYUY2 and the movie played right side up but I did'nt know if it would work to conver to YV12 in one part of the script and then to conver to YUY2 in another part. I think this convolution plugin requires YV12.

Thanks in advance,

VC

You can do colorspace conversions as many times as you like in a script, but its best to limit the use of it as those conversions are not lossless. QuEnc works with YV12 btw.

Just out of curiosity, is this script serving straight off the timeline of Premiere Pro??

also

Have you had success in importing an .AVS script into Premiere PRo??

No I got this script from the DV guide at www.doom9.org. I had troubles at fiorst because I did not not have the Convolution3D plugin already installed. I haven't tried importing an Avisynth script into Premier Pro. Why would I want to do that? Let me know what I could gain by importing the script into premier.
Also thanks for the tip about QuENC Thor.

Thanks,

I also use AviSynth and Convolution3D but my script is a bit different. I can't find it now (I looked just yesterday actually) but I swear I got it from the AviSynth website i.e., how to properly do Convolution3D with an interlaced source.

Mine looks like this (and not is PICVideo MJPEG AVI captures not DV):

LoadPlugin("Convolution3d.dll")
avisource("D:\CAPTURE\capture.avi")
Trim(423,214536)
crop(6,8,-2,-8)
SeparateFields() 
even = SelectEven(last).Convolution3D (0, 6, 10, 6, 8, 2.8, 0)
odd = SelectOdd(last).Convolution3D (0, 6, 10, 6, 8, 2.8, 0) 
Interleave(even, odd) 
weave() 
AddBorders(8,8,8,8)
AssumeFPS(29.970, true)
ConvertToYUY2()

Notice my use of Convolution3D is very similiar to yours but does differ slightly as I don't have these two lines:

DoubleWeave.SelectOdd() 
FlipVertical

I understand what the 2nd one here does but not the 1st one???

Anyways keep in mind that I don't work with DV AVI but ...

Why do you have the ConvertToYV12() line before Convolution3D? My understanding is that the newest AviSynth 2.5x version of Convolution3D works with YUY2 so in short maybe you just need to use ConvertToYUY2() instead of ConvertToYv12() (upon loading the file) and cut out the ConvertToYUY2 at the end of the script.

In fact I have ConvertToYUY2 at the end of my script but I don't think I need it because when I don't use it ... it still works. I'm told PICVideo MJPEG uses YUY2 so maybe *I* don't use that but I can see that you would need it for DV AVI since DV AVI is what ... YV12? I thought I read that. But if it is YV12 then why the ConvertToYV12() at the start of the script?

hehehe

Not trying to confuse things ... just trying to help you out.

Plus I need to find that bit about Convolution3D ... you said it was in the DV section of the AviSynth website?

Because i get to import a DVD2AVI framserved video into Premiere. Worked great with 6.5..IT allowed me to take DVD footage, and create my own custom menus...
I just realized that Premiere Pro accepts .m2v's directly, so i'll see how that goes..
Plus the fact, many people would probably prefer to use AVISynth's filters rather than PRemiere's, like LanczosResize, or Convolution, etc...

You need the
DoubleWeave.SelectOdd() to handle the tff/bff issue with cce. This should be your next to last command before converttoyuy2() in your script. Just make sure that you do not select tff in CCE. This tff comes in different menus depending on what version of cce you are using. As far as the flipvertical just dont do this especially if you dont know what you are doing

[lpn1160]

don't know if this is relevant or not, but my tweak works as follows:
go to the registry key
hklm\software\microsoft\windowsNT\currentversion\d rivers32
enter a new string value, label it YV12, then modify it with divx.dll or xvid.dll both can decompress yv12.
CCE will then accept any yv12 input without the need to convert to yuy2() (assuming your input is yv12)

I did not end up using flip vertical instead I converted to YUY2 at the end of the script. This was the final script that worked for me:
AVISource("C:\Documents and Settings\daddy\My Documents\Adobe\Premiere Pro\7.0\Adobe.ds\arrowoflight\gknot\arrowforeditin gna.avi")
ConvertToYV12()
SeparateFields()
odd=SelectOdd.Convolution3D (1, 6, 10, 6, 8, 2.8, 0)
evn=SelectEven.Convolution3D (1, 6, 10, 6, 8, 2.8, 0)
Interleave(evn,odd)
Weave()
DoubleWeave.SelectOdd()
ConvertToYUY2()

The 12 nminute DVD turned out ok. The quality was not as good as I would have expected considering the high quality of the captured DV but iwasn't using a tripod and the images are not to stable. I think the camera man is the weak link.
Thanks for all of yor help. DVDRhelp.com has never let me down.

I think that will be a conversion, CCE will probably use the specified DLL file to convert the YV12 to YUY2, the same loss will be there as if avisynth converted it to YUY2. Theres a big chance avisynth can do it just as good or better. No matter what driver you use to make a colorspace conversion, CCE still can NOT process YV12, so there IS a conversion.

videocheese,

what's your CAM make ??

I use TRV22. Great dv cam, w/ great lens - output quality very good. Not too
much noise under low light, but not the greatest under such, either, but still
better than my ZR-10 :P

I think that the only time when you should use any kind of "filtering" for dv cam
home footage is when there is too low a ligth source (low light conditions)
Outside footage should not require any filtering (ie, your Convolusion3D)

I think that the mans worse enemy when footaging is when cam is in hands and man pans cams w/out any "smooth control motion" up/down/left/right etc.
.
This make encoding the Interlace source much worse because the separation
of fields are greater (IMO)

Regarding your script..
Are you de-interlacing there ??

You really should encode with Interlace (MPEG-2)

My camera is a Canon GL2. I really like it. I didn't have my tripod with me for this particular event that I was filming and I just didn't do a good job holding the camera steady.
I did not deinterlace this. Should I be deinterlacing? I read that If intend to show this on a TV then I should not deinterlace. I'm going to now try to convert to Divx and for this I will attemp to to deinterlace since my intent is for PC viewing.
