Abnormal projected file sizes in VirtualDub???

[Drelletje]

Not having used VirtualDub for a month or so, I find that when I want to compress movies now, using DivX 5.02 for the video and some APDCM 22-bit for the audio, the projected file sizes are ridiculously large, like 8000 to 120000MB(!!!) for files that are originally up to 700MB.

As far as I know I don't have my DivX configured in any abnormal way: encoding bitrate 2000Kbps, max quantizer 4, min quantizer 2 and default settings for the rest I think.

I didn't use to have this problem before; any idea what could be causing it?

Thanks a lot in advance!

Mmm, just now tried uninstalling 1.4.10 and installing 1.4.11. No difference whatsoever .

Example? OK, here goes: a random movie with an (encoding bitrate at 800kbps just to make sure this is not causing the problem): after only 1000 (out of 165,000) frames the video data is up to 300 MB (!!!); the audio (Windows Media Audio V2) 7000 KB. Both way to much, it seems to me.

Oh, and projected file size: 50,000 MB -- and no, I'm not being inaccurate with my zeroes...

Oh, and it turns out that it's not only DivX 5.02 that causes these ridiculous file sizes; DivX 4.12, XviD MPEG-4 and several others I've tried (with default settings) also give a projected file size of around 50,000MB.

In fact the only way I can get sub 1GB file sizes is by selecting direct stream copy for video and audio...

If anyone knows how to solve this, pleazzze help, I'm really getting desperate!

not to sound elitist, but you are doing something wrong.

You are positive you have the video/compression set to something realistic and you have video/full processing or fast recompressed selected?

Are you sure your're reading the projected file size correctly, it's in bytes.

[Drelletje]

Snowmoon, you're not being elitist at all; I'm sure I must be doing something completely stupid.

However, my settings really are as I say they are and the projected file size really truly honestly is 50,000 MB -- I doublechecked and VirtualDub at least in my case definitely specifies MB not bytes...

Oh and Full processing mode and Fast recompress? Tried both; doesn't make any difference.

I remain absolutely convinced that you're correct in saying that I'm doing something very wrong -- just can't figure out what...

Mmm, it just occurred to me that before, when I didn't have these problems, whenever I loaded a movie into VirtualDub it took a couple of seconds, during which the program displayed a little progress indicator, until the movie was completely loaded. Now movies seem to be loaded instantaneously; I don't see a progress meter anymore. Wonder if this is relevant?

[snowmoon]

I have never seen a progress bar unless the AVI was corrupt or you are openeing .mpg files.

[Drelletje]

Mmm, well maybe it was with mpeg files... I'm afraid my memory is not terribly good at these things. I usually figure out how to use some application but the knowledge fades very quickly if I don't use it for a couple of weeks.

Anyway, the important thing is that all seems to be back to normal!

Trying to save a file a couple of minutes ago, I got an error msg saying that the required spyware was not running -- true, I'm an avid user of Ad-Aware -- and that I had to reinstall that for DivX 5.02 to work again .

As I had removed all that crap, I uninstalled DivX and did a fresh install. And whaddayaknow, VirtualDub worked again.

So it seems that removing the DivX spyware really messed up my system, as not only did VirtualDub cease to work with this codec, but in fact with all the recompression codecs I have installed, both video and audio .

Wonder of any other spyware haters have had similar experiences -- and what they did about it ???
