I dont think what i want can be done.

I have 30 separate video clips. I want to add a 5 second lead to each clip. That is all.

I have never written or run a script before. I can deal with writing a script, but i dont understand how regions help me. As I understand it, a region spans a section on the time line. So how is a region helping me have each track render to a separate file?

Here is what I have.

1) I imported all 30 of my video clips
2) I added a lead in title

Now I want to render each track (some with audio, some without) to a separate file. It is fine if they are not named right for now; I can rename them later. Does the batch renderer do this? I found virtually no documentation on scripts or how they work.

[Bryan Wells]

I mean so each file that is opened will be rendered to the same named file as the file that was opened.

Can I have the regions rendered out to indentically named files in another directory?

I tried the noise filter I posted on the raw avi’s that I imported into vegas but there were problems with color conversions I did not figure out. I render from vegas out to mpg2 (NTSC DVD) and then use AviSynth to render the meg2 from Vegas as mpg2 again. I could have gone to AVI from vegas too I am guessing, but I didnt have the time to figure it all out. I would have liked to go stright from the raw avi through the Avisynth filter in vegas. It should work and I am sure if I messed with it enough, it would have worked.

For my low-light IR video, it AviSynth was much better. I am sure for others, its not so noticable.

I discovered a great solution for a good noise reduction method. The output of the following script was much better than any other I have tried.

I used AviSynth and a user-provided script. I used a program called Link2 which wraps the avs script with an avi wrapper so that Vegas opens the wrapped avi for rendering. It worked very well. AviSynth is the frameserver, and link2 connects Vegas to the frame server. For some reason, the avi link2 gave me was missing the audio, but I did not need it so I did not try and figure that out.

Here is my avs script for use with AviSynth. As you can see, you need to get the plugins from the AviSynth plugin download page.

And you need link2: http://www.videotools.net

#loadplugin(“e:Avisynth_2.5oldPluginsmvtools.dll”)

LoadPlugin(“MPEGDecoder.dll”)

{

o=i.doubleweave().selectodd().tomsmocomp(-1,se,0)
interleave(e,o)
}

function reYV12(clip i)
{
yx=i.converttoyv12().greyscale()
x=i.separatefields().separatefields().selectevery(4,0,2).weave()
ux=x.utoy().converttoyv12()
vx=x.vtoy().converttoyv12()
ytouv(ux,vx,yx)
}

function manaodenoise(clip source)
{
function efficace(clip c, bool backward, int del)
{
v = c.mvanalyse(isb = backward, lambda = 1000, blksize = 8, delta = del, idx = 1, pel = 2)
d = c.mvcompensate(v, mode = 1, thscd1 = 2500, thscd2 = 170).deblock(quant = 30)
return v.mvchangecompensate(d)
}

bw3 = source.efficace(false, 3)
bw2 = source.efficace(false, 2)
bw1 = source.efficace(false, 1)
fw1 = source.efficace(true, 1)
fw2 = source.efficace(true, 2)
fw3 = source.efficace(true, 3)
source.mvdenoise(bw3, bw2, bw1, fw1, fw2, fw3, thsad = 2500, thmv = 200, tht = 30, thscd1 = 2500, thscd2 = 170)
}

I just installed it like you did, exited Vegas and found the Dynamic noise filter in the same place as all my others near the top of the list.

[Bryan Wells]

I tried the noise remover you recommended and it made the video a lot better. Thanks!

I was playing around with AviSynth and its plugins. There are a lot of filters people have written to remove noise, but I do not understand how to run the filter and save the output. I can play the filter in windows media player. Is there some way to use AviSynth from Vegas? DOes anyone know what I need to do to save an AVI after the filter I want has been applied?

[Bryan Wells]

Can you give me the specific steps and settings you used to improve the video? I would really appreciate a look at what works. Can you send me your project file or a sequence of the steps you used?

Thanks

In my IR brake light set up, I am currently covering the red brake light lens with the IR filter, so another option would be for me to remove the red lens and use only the IR fliter. But I am not sure if any of this will help, since the IR light being emitted by the brake light is probably not being reduced by the red lens.

Does anyone have any idea of how the brake light will effect the IR light with respect to using only the IR filter without the red lens or using both the IR filter and the red lens, or not using the IR filter at all and only using the red lens of the automobile brake light?
