| Creating / converting DVDs with Devede: Disk usage bar underestimates size! |
| nicolaidenmark posted 2008 Aug 21 03:07 |
| Hello all,
I'm new here and I have a problem, which I hope you will be able to help me out with. I have some dvd isos which are NTSC and I want to convert them to Pal. But when I load the original iso (which fits on a DVDR), the disk usage bar says it's too big to fit on 4.7 GB disk. So, I have to reduce the video rate to make it fit (99% of disk is used according to the bar). Then I start converting and making the iso. When finished, however, the iso turns out to be 5+ GBs and to big for a regular 4.7 disk. This means that I have to shrink the PAL image in K9 Copy to make it fit on a 4.7. :evil: How come I cannot trust Devede's analysis of disk usage? I have read a Guide saying that the disk usage always OVERestimates the size. But the oposite thing is hapening to me. :? I'm runing Linux vers. of Devede 3.10. It did not havee this problem with Ubuntu's repository install (2.16). :? Lastly, how do I keep the original menu? The menu screen is there but I can't navigate on it... :cry: |

| I'm not going to be much help with your problem but I do have a question for you. Why are you wanting to convert a dvd from ntsc to pal? Doesn't most pal equipment play ntsc video?
While I have devede on my machine I have actually never used it so I can't help with diagnosing your problem. I prefer to encode my video and audio separately and then author in an authoring program (I use dvdlab/wine). Also it's very difficult to convert a dvd menus and all from ntsc to pal. Converting the main feature isn't hard but converting and retaining working menus is very difficult... |

| normally yes. But my tv is very old hence it doesn't |

| Oh. Okay then. Well what I would suggest would be to extract your movies main feature (usually the largest vob on the disc) and add those files into devede for it to do the conversion. You will lose the menus but it should make your conversion less troublesome. |

| This happens from time to time with any compression program and codec. Depending on the material you're compressing, the codec/program can over/under shoot the bitrate. This happens with ffmpeg, mencoder, and mpeg2enc while using CQ or 1 pass vbr, The only way to accurately obtain a certain size is with multipass VBR or use CBR.
If Devede is over shooting the size by 10%, just lower the bitrate by 10% and encode again. Converting for NTSC-PAL, I doubt you'd be able to keep the menu without reauthoring by hand. You could rip the menu vobs by PGC, encode to PAL content, then reauthor by hand with DVDStyler. That would be a bit of work though ;) |
