Cutting Ripped AVI

[quxote]

Hello,

I recently converted my home movies from VHS to DVD using a standalone DVD Recorder. I then ripped the DVD using Magic DVD Ripper to my hard drive. I now have several avi files that I want to cut into pieces for editing. I was able to do this using Virtual Dub but I noticed that when I saved the AVI file the pieces are larger then the whole AVI. I am thinking it has to do with the compression I used (Xvid). I used GSpot to see what codec was used on the original AVI and it is also Xvid. Shoud just cutting a AVI result in all the cut pieces being the same sixze as the original AVI?

Am I doing somethingg wrong? Is there a better program to use to cut the AVI and also remove scetions of it?

Each AVI file has its own header so the sum of 10 clips will be a tiny bit bigger than the 1 source file. But I suspect you rerendered the file with a higher bitrate.

Put VirtualDub into Video -> Direct Stream Copy mode. Segments you save must start on key frames though.

If you use one of the lastest versions of VirtualDub you can use Video -> Smart Rendering. Then you can cut anywhere you want and only cut GOPs will be rerendered.

I am using VDub 1.7.8 and just found the Smart Render option which greatly reduces the files size when cutting. I guess this brings me to another question when suing Smart Render do I use Full Processing or Direct Stream for the video?

Also for the audio I get that message when I open it about the VBR should I use Direct or Full Processing for the audio? If using Full what sould I set the Audio compression at? GSpot says the orginal is MPEG -3 44 kbs but that option is not available in VDub, I only have 40 or 48 kbs

Since VirtualDub's handling of VBR audio is borked you will have to reencode your audio. Use Audio -> Full Processing Mode, Audio -> Convert (if necessary), then Audio Compression. I use the Lame ACM codec, 48 KHz sampling, 192 kbps or 224 kbps.

Also look into a program called AVIDemux - ignore the name...it has very little to do with demuxing, handles VBR audio with ease and is very similar to VDub.
