Resize with Virtualdub

[antoniosgubba]

I've just about given up on this!
I'm trying to create an svcd with Mainconcept...the problem is the one that everyone seems to have with mainconcept...ie, I cannot preserve the original aspect ratio (widescreen movie). In advanced options I can change the aspect ration to 16:9, which nearly does the job...but the people in the movie look just a bit too tall and thin!...there is another option of 2.21:1, which would be perfect if it wasn't greyed out!
I've read the other posts about this problem..I've tried avisynth but I just cannot get my head around that program!
The other posts mention frameserving with virtualdub...now I know how to frameserve with Virtualdub ok...but I cannot for the life of me get virtualdub to resize and add borders. I've looked in filters and found the resize option, but I can't get it to work
Can someone please explain to me, in as simple language as possible please , just how I set the resize and add border functions when frameserving with virtualdub....bear in mind I'm thick!

Thanks!

The Mainconcept can handle the final SVCD resizing so you just need to add the borders with the VirtualDub resize option to pad it out to a 4:3 aspect ratio since this will be the viewing ratio.

In VirtualDUB use the built-in RESIZE filter with settings

New Width: (the current width of the video)
New Height: (the current height)
Filter Mode: Bicubic
Tick 'Expand frame and letterbox image'
Frame Width: (the current width)
Frame Height: (the current width x 0.75) that is, 3/4 of the width.

This will add black borders top & bottom and make the video a ratio of 4:3 but preserving the ratio of the actual video. Mainconcept will resize this to the SVCD standard and it should play back correctly.

Thank you Bunyip ...I'll give that a try.

Just tried it out....works perfect

Thanks again Bunyip!

Dumb question...do you have to recompress in VD to get teh fitlers and resizing to work, or does it do it when frameserving to other apps?

Nope....just open movie in virtualdub, do the resize that bunyip explained, start the frameserver, save the "movie".vdr.avi, open your mpeg encoder and use the "movie".vdr.avi as video source and the WAV (which you should have already extracted with virtualdub) as the audio source.

Thanks for the info!!!

Note to antoniosgubba & LSchafroth.
Separating the audio from the video is only necessary if you are getting synchronisation problems in the final MPEG file, you can frameserve both directly from virtualdub to MC.

It saves a step.

Thanks Bunyip, ...I tend to always separate the WAV with Virtualdub now though as a matter of habit!...I used to have problems with sync if I didn't, especially with VBR audio.

Bunnyzip is my hero , the Awsome Austrailian !!

Bunnyzip helped me with a simple (to him) avisynth script to work wonderfully with Mainconcept. This allows me to keep the aspect ratio for those wide screen movies, to play on my conventional TV, yet Mainconcept encodes at 4:3.
Isn't the few commands you showed me more efficient that using Vdub ?

I have another question to ask you, but I'm afraid to impose more on you, but I will later.

If you are ever in Colorado Mr Zip (I assume that Bunny is your first name and Zip if your last name), please come by.

When i open a wav file as the audio source it says " no audio found! " ?? What did i wrong?

[antoniosgubba]

Hmmmm...I assume you extracted the audio to WAV with virtualdub?...if so the only thing I can think of is that you used "direct stream copy" instead of "full processing mode"...open your movie with virtualdub, click the audio tab and click "full processing mode", click compression and make sure its set to "no compression" and also click conversion and change to 44100hz. then click File tab and save WAV.

[bighousie]

I used indeed direct stream. I'll give it a try with fullprocessing.

[antoniosgubba]

Aha....that was the problem then!

I'm sure it will work when you've used full processing mode

[bighousie]

Yep, now it did his work! Thanks for the advice.
