Hi folks, I'm a bit new to this program. I have an AVI file that i wanted to change the brightness and Gamma (Cromma Smoother). I loaded the filters and made my change and was happy with the sample screens. I have to be in 'Full Processing Mode' and when i chose "Save as AVI", it all started to work well - until i got the "Low on Disk Space" msg. Uh oh, i thought, i had 50GB spare? As you might know, the file was going to go well over 100Gb (it's a home D-Cam movie - 2 hours long). Am i doing something wrong? I use Virtualdub 1.6.15 (build 24442). I hoped to save the changes and get back the same (roughly), new AVI file size. Any help would be appreciated. Thanks. Fred. I use
dont use virtual dub its to damn hard use pocket divx encoder. its very easy and free. to use just google it
By default in Full Processing mode you get RAW RGB24, so that is 3bytes per pixel which can end up very large. You need to select a compressor, what you select depends on what you are trying to achieve. As for pocket divx encoder, if you wanted XviD or libavcodec MPEG-4 output (despite the name it can't actually encode DivX) then it would be ok, assuming that it lets you access mencoders filters to adjust brightness, etc. I actually prefer XviD to DivX, I just don't like apps with DivX in the name that have nothing to do with DivX. Should be called pocket XviD encoder or maybe Pocket MPEG4 encoder.
Hi guys, thanks for the reply's. So, ok, i don't use rogeball's d*** encoder. I dont like the way all the 'key' names are links to the topics..... So, Celtic_d. Good to know and see why now the file size became too big - thanks. That x*** to d*** software. Is that all i need to increase the brightness and Gamma of an existing AVI file and resave it to the (or roundabouts), same size file? Look. I'm still not sure of the file name. Is it xvidtodivx, or xvid2divx, or xv2dv that i am looking for? Cheers, Fred.
Well if your source is DV, then re-saving as DV would give you the same size. DV is however lossy, so you will lose quality. You also lose quality by filtering in VDub since that means converting to RGB24 and back (PAL DV is 4:2:0, NTSC 4:1:1).
Hi Celtic_d, Yes the original source was DV and the files (4 AVI's on a DVD), were given to me (as i'm an expert apparently!), so that i can increase the brightness and gamma. As i had (they knew i did some dvd 'stuff'), Virualdub and a few other programs, i didn't see it as a problem - allthough i have never had to actualy 'manipulate' a dvd in such a way. My initial post was to find out why the file was so big and (or) get the name of some other software that would do the same job without going to big. At this stage i would rather (to save me time as i got roped into this), just find the software if that's ok. Thanks, Fred.
The person probably expects a DVD containing DV files with the brightness corrected, right? So all you really need to do is do what you have been doing, but select a DV codec under compression.
Hi again Celtic_d. Yes, i could do what i am doing. Problem is i don't have the HD space to do it. Even if i deleted a WHOLE ton of stuff, just to get it 'converted' with the Brighness and Gamma done. How the heck do i get it back down to 3-4GB's? Saying that though - just came to mind - i would need that same 'original' HD space + the working area + the finished product. I'm not sure if i have mislead you and other people that have viewed this post - you gave me the answer as to why it was so big. But all i ask now is for a piece of SW that will allow me to change the Brightness and Gamma, without a massive file at the end Thanks, Fred.
Technically you would only need 3-4GB's space since you can read it from the DVD. I didn't say do exactly what you are doing, I said do what you were doing, but select a DV codec rather than none. If your source is DV, then your output would be the same size.
