Avisynth Script

[edsmith77]

Good Morning to All.
After spending seveal hours last nite trying to get an Avisynth script to work as desired, I finally gave up. Background, I have a dvd rip (vob files) and a .d2v and .wav file from dvd2avi. The video is 740x480 16:9 at 29.97. I then fed that into FitCD and selected 1/2 DVD as the output and saved the script created. Basically, what I am trying to get is a 352x480 mpeg-2 4:3 full screen video. I then feed the fitCD script into CCE (basic version) select mpeg2 and encode a 1 minute clip (don't want to waste to much time,here). What I get is a shrunk down version of the original. That is, a video that is still in 16:9 but is only about 1/4 the original size with HUGH black borders. Aside from this small (literally) matter all else is fine.
The script sans the loadin and source statements are:
BiCubicResize(320,480,1/3,1/3,0,0,720,480)
AddBorder(0,1,0,1)

I have tried the following variants (ALL without success).
Bicubicresize(352,480)

Bilinearresize(352,480,0,0,720,480)
AddBorder(0,16,0,16)

BiCubicResize(352,478,1/3,1/3,0,0,720,480)

I even went to the SVCD standard
BiCubicResize(480,480,1/3,1/3,0,0,720,480)
without luck.

If it makes more sense, I also ran the same type of process through TmpGenC and got exactly what was desired. The process was to load up the standard ntsc SVCD template (the non film one), load in the d2v and wav files, then on the video tab (under settings) change the size from 720x480 to 352x480, pick an output file name and hit start (for the same 1 min clip) and voila a full screen 4:3 version of the original. In about 15 minutes longer than it takes CCE. Definate speed advantage to CCE here. However, ........ the results are not what I want.

Surely, there has to be some combination of resize, addborder and cropping filters in avisynth that will get me to my final output.

What about it avisynth guys.?

P.S. I have also tried the guide on the left for avisynth but alas no joy.

I'd guess in your FitCD, your source files were PAL, which is then being checked on your output

hence - Bilinearresize(352,480,0,0,720,480)

if you want ntsc, uncheck the PAL box in your FitCD for your desired output settings.

Just a guess in looking over this.

Spidey,
Thanks for taking the time to reply, it is appreciated.
Unfortunately, the PAL box was not checked.
Since, I do not own a DVD burner (but will in the future, when I get richer), I am trying to make CVDs (this is good news now that I can get my player to play them with a modified header trick).
I do like the speed increase with CCE over tmpgenc but have not yet figured out how to get the same results (screen size that is).
On a similar note, I can take the cce created file an run it into a bitrate viewer. Which tells me a lot of information about the way the file was encoded. Of interest is the resolution, aspect ratio and bit rate. Using the mentioned scripts and this bit rate viewer, the resolution does not change it remains 720x480 after encoding at mpeg2. However, if I take the EXACT same script only changing to 352x240 (vice 352x480) and encode to mpeg1 with cce. The screen picture comes out as expected.

Just not enough knowledge here.

If I understand correctly, try this-

Check your CCE template (video tab) to see if 'DVD Compliant' (or something like that) is checked. If it IS, then output WILL BE 720x480- it automatically resizes to that and adds the border. I ran into same thing downsizing to 352x480 via avisynth and it took me forever to figure out what was glitching up. Just uncheck 'DVD compliant' and it should be okay. I think. ;o)

rob1,
Thanks you were absolutely right. That cured the problem. I feel kinda stupid for not seeing it myself.
Thanks for helping.
