Vdub blur issues

[bigMach™]

Its been years since I used vdub, but remember that I successfully blurred an avi logo.

Im trying to this now, and I'm having some problems.

I'm suing latest vdub and logoaway4.01, with an avi video.
Media info reports following:

I have installed official xvid codec, and made settings close as possible to avi info.
I then unnstalled xvid and installed ffdshow, but see no place to change setting, there is no xvid in encode dropdown box..

So I have added logoaway filter, and blurred area.
I have used curve editor to blur only several parts of the video, each around 60 seconds.
I have ticked full processing mode+smart rendering ( to only encode selected parts, and direct stream rest of video), and direct stream for audio.

Then save as avi.

The problems I have:

1. When it hits the parts selected with the curve editor, the encoding becomes ~1fps! it took around 2hrs just to process several 60 second sections in the avi...

2. the parts that were processed had the side cropped off! as soon as the 60sec blur passed, the video went back to normal ( in the filter window, the logoaway filter had [C] [B] next to it, I know it needs the blend option on, but what is [C], as I cannot get rid of it?)



Is this normal? I don't remember it being like this using it years ago!


Thanks.

any other program that can blur without re-encoding entire video?

[Gravitator]

Hi!
One plot (low complexity): - It should be cut video material into three parts (as the nearest keyframe).
The resulting segments 1 and 3 are left untouched, 2 working part.
Next comes the filtering> encoding> bonding.
A plurality of portions (high complexity) - The more areas undergoes filtering the more the program will have to create pieces / glue at the end.

the encoding becomes ~1fps! it took around 2hrs just to process several 60 second sections in the avi...

This too is super slow. Single-pass?

[bigMach™]

XVID, 1200kbps, single pass.
Basically tried to set it as close to the avi as possible.

Not sure why it takes so long, or crops the sides of the sections marked with the curve editor...

You mean the appointment order filters separately for each segment? This is how to work with layers (each layer / track has its own filters).
Try through AviUtl (Support). Only I have no idea if he can do it > ''+smart rendering ( to only encode selected parts, and direct stream rest of video)''.

I will check it tonight.

Have a look at screenshot of what I mean.

No, it doesn't do "smart rendering"

Just save your file to loseless AVI if you want minimum quality lost.

[Gravitator]

At me also start 1fps and then increase above 20 (the longer - the faster).
My result is normal (nope problems black bars). Can you give a sample of the original and the processed file?

[DarrellS]

Leave XviD settings alone > use Curve editor with filter in blend mode as shown above and under Video > choose Compression > XviD > under Video choose Smart Render and save new avi. Virtualdub will only re-encode the blurred sections and direct stream copy the rest.


Make sure when using the curve editor that you get the bottom points all the way down or you'll end up re-encoding the whole file (or however long that section is) and if you fail to set compression to XviD (or whatever the original encoder was), you will be saving a file with no compression which will take forever and create a huge file.
