I have couple of Children's DVD here at home (Learn to Count, Colors, etc) I would like to rip. I assume, that if I want to have the "Loseless" format, all I have to do is the copy the .vob file from the DVD to my hard-disk (and can get ride of the DVD if I want). But if I want a lossy format, It looks like it possible to do it directly with FFMPEG by referencing the .vob file. I used FFMPEG in the past to convert VHS HuffYuv captures into Lossy format using this command:
So obviously, the source is going to be vob files instead of AviSynth script. But what about the rest? Couple of questions:Code:ffmpeg64 -i "E:\test\test.avs" -c:v libx264 -preset slow -crf 18 -pix_fmt yuv420p -vf setsar=12/11 -c:a libfdk_aac "results.mp4"
1. Preset slow and crf 18 sounds a bit like over-kill for a Children's DVD. What would be a saner option?
2. I assume, I don't have to state YUV 420 because unlike the VHS capture I captured at 422, DVDs are at 420 by default?
3. what about setsar? I'm using is to have an proper aspect ratio when the TV scale it up. But 12/11 is for PAL capture (576x720). Do I even need to set it on DVD content?
4. Is there any other DVD specific options I should be aware of and state to FFMPEG when handling DVD?
5. The DVD disk I was checking was interlaced. Are all DVDs interlaced? or some are progressive? Will interlaced content will benefit from de-interlacing with QTGMC (and in that case, I assume I will need to write AviSynch script that loads the VOB file).

I'm not sure if it's Copy protected. I can play the Vob files, so I assume no? also - isn't the Vob files already a loseless format? why do I need to convert it into mkv?
Hi again ProWo, thanks for the help.
Right, I'm sorry. In my mind the Vob file was "Loseless", because that's the best version I own. But your of-course right, I assume DVD never really coming in any Loseless format (unless perhaps it's a very short DVD?).
What do you mean by "Rip"? Isn't it just a matter of copying the file from the DVD into the hard-drive? a normal system copy? or "Rip" does more then just that? I will check clever Ffmpeg-GUI. See what kind of parameters it using for 1:1 vob to mp4. But on this specific case, I see no reason to have a "learn the ABC" 30 minutes video at 3.5G. I wouldn't mind saving the DVD, and only keep a lossy format on the side.
Question is - can I do it with the parameters above? or re-encoding lossy into lossy is really a bad idea?
By the way, I have completely missed the "Video Conversion" section of the forum. This is probably belongs there. So if an Admin can remove it - it can be great, or I can close/re-open over there.

If you want mantain the whole menus and trailers etc then just copy the VIDEO_TS folder to your HDD. A good player is then able to play your full DVD.
Otherwise you could rip the full movies to single Vob files. (1 vob per movie).
Oh I see now. A single DVD might have multiple Vob files. I see, thank you ProWo! Will move the Lossy re-encoding question into video conversion.
