Disk space and frame rate conversion

[Robert_Neville]

How much disk space does one need for a 120 minute frame rate XVID to AVI conversion? How much disk space does one need for a 120 minute AVI to VCD mpeg 1 conversion?

My disk space seems insufficient for a frame rate conversion (11.6 Gig free). Let me know if you could give me some ball park figures.

I can't imagine your 11.6 Gig free being a problem. I've found it's not good to go much below 3Gig Free with WinXP or the system seems to get very slow (probably because of a reduced cache size on the HDD) but I once used an old 12GB HDD to rip and convert DVD discs to DivX without problems (this was on an older slow ass computer). So 11.6 should be more than enough to convert an Xvid to just about any format including a full 4.3GB DVD-R

P.S.
When I was using the 12GB drive it was a SECOND HDD so I didn't have to worry about the cache size thing since that was on my OTHER HDD but even if you only have a single HDD with 11.6GB free it should be more than enough to convert your Xvid to VCD or SVCD or even an mpeg-2 DVD file. BTW the Xvid is already an AVI type file so why would you want to convert it to AVI using aother codec? That doesn't make much sense!

Fulci,

Well, VirtualDub told me that my disk space was insufficient when executing an AVI un-compression. I must have done something wrong. Essentially, my objective involves converting a XVID AVI file in a VCD playable on most rudimentary DVD players.

Does one need to convert the XVID to an un-compressed format before re-encode? This question may seem elementary, yet I am familiar with MP3 to Wav to CD.

Could one directly convert from an XVID to mpeg 1 wihtout quality loss?

The original question has me perplex. Why would VirtualDub require more than 11.9 gigs for a conversion process?

Yes you can convert from XVID to MPEG-1 or MPEG-2
There is no need to make an uncompressed back-up of the XVID
You should be able to open the XVID AVI file directly in TMPGEnc or whatever MPEG-1/MPEG-2 encoder you use.

The reason why you don't have enough space is that you are trying to save the XVID in VirtualDub as an UNCOMPRESSED RGB file. This takes up a HUGE amount of HDD space but it not required to create a MPEG-1 VCD compliant file.

Uncompressed avi's are very large (not sure how big, maybe someone else has some figures), but you shouldn't have to uncompress the video to encode, as long as you have the codec installed and your encoder will accept your file. Direct from Xvid to mpeg would be the preferred method. Many people (like me) do prefer to uncompress the audio to wav and use that as the audio source.

Are you using Vdub for a frame rate conversion? If that's the case, you can save the disk space and eliminate the need for an intermediate (large, uncompressed) file by frameserving directly from Vdub to your encoder. Check the guides for instructions on frameserving.
