VirtualDub Resize Filter

[Sebby]

I'm trying to simply resize an AVI to 640x360 using VirtualDub 1.6.9. I go to Video > Filters... > Add... > resize > OK, input the size details, change the filter mode to precise bicubic (A=-0.60), then OK everything. I then select Video > Direct stream copy, then go File > Save as AVI...

However, the size of the video in the new file remains unchanged.

I know I'm being stupid. What am I doing wrong?

Many thanks.

You need to select full processing mode when using any filters.

Just a tip.
Don't forget to choose a new video compressor since you are going to be recompressing the file or it probably default to RGB no compression (unless that's what you want) .

Ah, that would probably explain it. That's gonna take ages.

I'll tell you what I'm trying to do; perhaps there's an easier way. I'm trying to resize around 20 AVIs that are 640x326. The reason I'm trying to resize them is because I'm trying to convert them in TMPGEnc, and it's complaining that the resolution is illegal ( needs to be in multiples of 8 ).

Is there a better way of doing it? I'd prefer it if I could just get TMPGEnc to ignore the size!

Frameserve the output from vdub to tmpgenc. It won't create an intermediate file and that will save some time (and disk space). I recall older versions of vdub 1.4 (I think) had a good explanation of frameserving under the help menu. It is frequently discussed here if you are not sure how to do it.

I haven't used tmpgenc extensively in the last while but I seem to recall that you can also adjust the framesize (res) within tmpgenc. Look for unlock.mcf under the extra subdirectory of tmpgenc. Use the load feature at the beginning of the program.

Thanks.

On the advanced tab, select Centered, Custom size.

Download fitcd and avisynth. Use fitcd to write a resize script for avisynth. It works a lot faster than resizing and frameserving with virtualdub.

the script for resizing is easy for avisynth

# 16:9 encoding
AviSource("W:\project9_5\file33b.avi", false)
ConvertToYUY2()
AssumeFPS(23.976,False)
LanczosResize(632,440,0.0,0.6)
AddBorders(44,20,44,20)

adjust as required for your application

Tmpgenc shouldn't complain about the size unless you are not choosing a compliant vcd/svcd/dvd resolution after you load the video file in.
