FFMPEG and avisynth..truncating my video!!!!!!

[raschko]

I've been using AVISYNTH to render out video clips through the command line using FFMPEG.
(about 13 seconds a piece)

But when exporting, the render sequence is cut short around 50 percent and the video is made.
Oddly enough even though its missing frames..I can still play the video. *scratches head*

The error occurs when trying to use one of synths resize functions.

Is FFMPEGs use of that frame server broken, or am I witting this command wrong?

ffmpeg -i test.avs -f mpeg -bt 3000k compiled.mpg

Or if someone has experience with avisynth, maybe my script is off.
(will display if asked)


Thank you.

Version of ffmpeg is really important. Post your .AVS file.

avs script:

mFst = ImageSource("***\For forum\0.jpg",0,450,29.97).fadein(90)
mFst = animate(mFst,0,450,"crop",0,350,576,384, 0,0,576,384)
mFst = BicubicResize(mFst,720,480,0,0.75)

mLst = ImageSource("***\For forum\1.jpg",0,450,29.97).fadeout(90)
mLst = animate(mLst,0,450,"crop",0,0,576,384, 0,405,576,384)
mLst = BicubicResize(mLst,720,480,0,0.75)

mFst = dissolve(mFst,mLst,90)
mLst = 0
mFst = ConvertToYV12(mFst,interlaced=true)

return mFst

and my current ffmpeg build is 7760

the render sequence is cut short around 50 percent

How you check this?

[raschko]

You can compare the rendered number of frames over the total

(number of frame rendered*100)/total number of frames

[gadgetguy]

You do realize that Dissolve is effectively removing 90 frames, right?

Indeed, in order to disolve two source clips;
They are overlapped, which does shrink the video.

The issue is, I'm missing frames at the end..
IE: the video starts to fade into black but stops before reaching #000000

Quenc seems to solve the problem, but would rather have a command line app without a gui for flv/mpeg2 rendering.

[gadgetguy]

Exactly how many frames are you missing?
QuEnc can be run from command line. Most of the time I use it within bat files. I almost never use the gui.

Edit: Try fadeout2() and see if it takes you all the way to full black.

[Soopafresh]

Yup. Quenc will run from the cmd line - Mencoder, and HC as well

[raschko]

Will try tonight and see what occures.

[raschko]

HA! Got it working!
The programming interface I am using is Adobe Director.
And as such there is an extension to run command line applications.

This xtra is the issue. (after perusing the returned dll values)

So have switch to running a bat file..and everything seems to be in order.
