Need help huge file!

[Shifty268]

I have a AVI video that is 16 gb in size. The video qulity isn't that good but the audio is PCM audio which is uncompressed (i think). I want to make it smaller so it not such a big file on mp pc. I want to compress it but i just want to compress the audio not the video as the video not that good quality bad enough as it is.

Does anyone have any suggestions on how i could extract the audio then compress it then put back together again or any suggestions on how i could compress the audio and not the video.

Cheers !~~ShiFty~~!

Use Virtualdub. Under Video select "direct stream copy" so that it is saved as-is. Under audio select "full processing mode" then select compression and select your compression type and setup. Save avi.

How long is the video ? If it's run time is under 2hours, you could probably encode it to mpeg-2 with a couple of filters, get a file a quarter of the size, and not lose out on quality.

Hey there i tryed to open the video in Virtual Dub 1.5.10 and the "virtualDub error" window came up, it said:-

Couldn't locate decompressor for format 'dvsd' (unknown)

VirtualDub requires a Video for Windows (VFW) compatible codec to decompress video. DirectShow codecs, such as those by Windows Media Player, ar not suitable.

Hey there i got the video working with VirtualDub, i put the video on "direct stream copy" and the audio on "full prosessing mode", i then went to compression and selected a mp3 compression (224 kbit/s), then click file save it said the projected file size was only going to be around about 6 gb smaller than the origianl 16 gb file. I tryed to put the video on "full prosessing mode" and compress the video to divX and it had all these errors.

I want to know what you people think i should compress the audio & video to and how i can do that, i want a prettty good quality video with good audio that comes out about 2 gb

Heres a picture of the original 16 gb video:

Is it hand held home video ?

Frame serve it to some mpeg encoder, and encode to DVD spec. At 1.18 running length, you can use 7400 kbps video and 224 kbps AC3/MP2 audio with room to spare. No resizing needed, as it's already in DVD resolution. That'd bring it down to 4 GB+
