Then put those 150 clips on the Edius timeline and output the timeline as a single file, then that is what you will feed Virtualdub/Procoder.

Default convert

No that's not an option - each clip is extra, most of them have an extra menu, are in a folder-structure with a certain name each - otherwise it would be a chaos...
In that case it would be better to just do each file extra...

Somehow we need to work with a watchfolder or a batch-queue, keeping the file-name... otherwise it is just too much hassle and too much danger of doing mistakes...

thanks anyway for your help..
if anybody has an idea how to do that, let me know - thanks in advance!

Default size of video changing

I am using your virtual dub system to downcovert DVCPROHD (960x720) files to SD (as a 4:3 letterboxed version) for cable television. It does seem to eliminate alot of the "jazzies" im getting. I find this is mostly NOT from going HD to SD, but is caused from going 16:9 to at letterboxed 4:3.

Anyhow, the problem i've run into is with VIRTUAL DUB. It keeps changing my file to size 720 x 540. Even after I change the size in the filter:resize settings. I check the absolute box and enter 720 x 480. I'm also checking the "letterbox to aspect ratio" and entering 4:3 there. (ive also tried it with checking "do not letterbox or crop") But after click ok to apply the effect, it shows up in the filters window under output at 720x540 and then when i render the .vdr effect in VFAPI it is a 720x540 file. WHAT AM I DOING WRONG????

EDIT: Well looks like checking the "Do not letterbox or crop" DOES make a difference. Thats the only way the file size will remain the size I enter (720 x 480) So thats the answer. I'm leaving this post incase anyone else has this problem.

I wouldn't even mess with this procedure if I didn't have to make a Letterbox 4:3 version. That's what makes the video look the worse with antiailsing and jazzies it seems.
Thanks for any help here.

Default step 16 fails

First time I tried I got to Frame Server and got stuck there.
Second and third time Frame Server just resulted in picture back to large and no new window.
Has anyone got a clue?

I have tryd many ways to convert from HD 1920x1080 to SD, and the bast outcame for me is using Procoder 3.
What i do is:
Export the timeline to HQ or uncompressed
Open in PC3 ant export using:
System / Canopus HQ encoder or uncompressed.
for pal 720x576, 25fps, Upper Top field first, Aspect radio: 16/9 and audio 48khz 2ch.

Aply filters:
709 to 601 color correction.
Sharpen filter. you will need to find out config in the sharpen filter pending on the quality of each material.

You can do this using PC3 exporter from the timeline.

Usualy the Colorspace went realy bad using other softwere to do this.

I have mostly been using this for HDCAM material

15. Default filter mode Precise bicubic (A=-0.75) is fine but very slow to render, try Lanczos3 (not much difference in quality but quicker to encode).
You don't want to try that with an EX1 image. One of the problems of the downconvert is the resolution of his images, a lanczos interpolation will give you an awkfull pattern. The quality is allways the same, but you can have nice or ugly textures with the interpolation method.
For downconvert, lanczos = + moire, + noise, + blocks, + filesize
Is not a subjetive thing, just basic theory.

Not really!
This isn't an academical debate. Practical experience & subjectiv points of view have some influence for decisions!
Lanczos is more ringing in edges, but generally more sharpen. I didn't found any bad noise pattern or moire effect!
Looks fine in most cases!

Been having problems with this lately and struggling to resolve. Procoder or any other app is not opening the frameserved .avi file

Probably related to moving to Win 7 64.

Short movies frameserve and open OK. The problem is with long movies, over 2 hours approx. Guessing, possibly related to vfapi.avi files that go over 2gb approx in size.

It frustrates the hell out of me that we waste valuable time messing about with long workarounds. Why the hell can Grass Valley and others not put a simple Lanczos scaling filter tick box option into the export dialogue box???

I started this thread in Nov 2008. Its got the second highest number of views. In a few months, this thread will be 3 years old. Grass Valley response? ZERO!
