Resize/Compress VirtualDub help?

[GODDIS]

I got a avi file size 700mb 544x288

I took sharpen and warp size 640x480 in filter

And got out a 1.4Gb file size 640x480 with a bit lower quality

and then I took compression DivX 6.8.5 Codec which I didn't config or anything.. along with Audio compression MPEG Layer-3 which I also didn't config or so..

to make the size smaller but it came out as 1.3Gb or so..

So a little help? I want it to 700Mb but with 640x480

I started with this just yesterday and I want to know how to do : /

It's gonna look like crap (a bigger sharper frame will require more bitrate). But to get the same file size set the Divx bitrate to the same video bitrate as your source. I recommend a 2-pass encode to get as much quality as you can. Leave the audio set to Direct Stream Copy if you don't need to modify it. Otherwise, set the audio bitrate to the same audio bitrate as the source.

I don't seem to have 2-Pass?

Do you mean multipass?

[jagabo]

Yes, multipass. First Multipass 1st pass. Encode the video. The resulting file will have no video, the encoder is just examining each frame. Then set Multipass Nth pass, set the bitrate, and encode again. This time the output file will have your video.

so just for clearance..

my original (the source) avi file size 700mb 544x288

should I sharpen and warp size 640x480 in filter and then take Multipass 1st pass amd then set Multipass Nth pass, set the bitrate, and encode again?

Or is it possible to resize and compress at the same time?

Or how should I do this?

I don't have any memory of how the resize filter worked but I choosed warp size for some reason..

But a step by step from the source since I'm a bit confused cause this is all new : /

Currently I'm trying to compress the 1.4Gb warp sized file to 700 which I got from the source and it got a bit lowered quality.

This is a bad idea in many ways. It won't look better, only worse (as jagabo already told you, but apparently you ignored him). Why are you doing this?

Yes. And you use the same filters on both passes.

Or is it possible to resize and compress at the same time?

If you do it right, you will be resizing and compressing at the same time.

And have you even noticed that 640x480 is a 1.33:1 ratio while your source video (544x288) is 1.89:1? You're going to make every one look way too tall and thin by ruining the aspect ratio (unless you add the right amount of black bars above and below the video). Unless this warpedresize does something with which I'm not familiar, but it still can't be good.

Leave it alone, unless you have a very good reason for doing this.

As said I started wih this program 2 days ago... Furthermore I don't know jackshit about these things to begin with, thats why I'm here right?

But no1's gonna resize and compress my vids for me right? and I got about 60 of them.. I intend to learn this within this week and it would be mighty kind by you all if you want to help me. Should I now say something about the christmas times cliché to help me?

so aspect ratio and black bars then... your saying the problem is the picture will be off and appear offscreen? soultion is "add the right amount of black bars above and below the video" the warp size fixed this prob for me but I lost a bit of qulaity.

But if your supossed to resize and add black bars, then how do you do that?

More to the point is, "Why are you doing this in the first place?"

If you want to try and learn some video encoding, take a DVD, decrypt the movie onto the hard drive, and then run it through AutoGK to make an AVI. It's a good beginner's tool and will give you good results quickly. There are many guides for its use (not that you really need any), beginning with the ones on this site.

Upscaling low resolution, low quality, video to a higher resolution with the same bitrate will not improve its quality. It will only get worse. Even if you use higher bitrates (to support the higher resolution) you generally won't be increasing the quality.
