BD to DVD copy

[essexboyracer]

Scenario: I am trying to get our BD films onto a NAS (D-Link DNS-320 with self installed twonky - so no transcoding). I have achieved all our DVD ok, using ffmpeg and am now trying our BD films.

The process is as follows

1. Insert BD disc and get the film chapter using makemkv.com
2. Resulting MKV file plays in BD HD format using VLC
3. Encode the *.mkv using ffmpeg
4. Resulting file works via NAS Twonky DLNA on our Sony KDL-32W5500, but skips frames every second or so, resulting in jumpy video

The command used is:

ffmpeg -i title00.mkv -target pal-dvd title00.mpg

I am on Xubuntu 11.10 and have already tried their forums, which if you're reading this you should also read:

This is not really a ripping question. It would have been better to have put this under Video Conversion.

Anyway, I am hardly an ffmpeg expert, but your use of -target pal-dvd is likely your problem. BD input is most likely at 24 fps and converting to PAL DVD changes the frame rate to 25 fps. You're going to get at least minimal artifacts anytime you do a frame rate conversion. Is there a good reason that I don't know about as to why you cannot leave this rips alone? Or could you just convert them to 24fps DVD compatible videos instead?

So you know my level and understanding of such things, mod's please move this thread if appropriate.

Leave the rips alone, what as? they start as MKV files, which the TV DLNA wont play (only AVCHD and mpeg2) www.sony.co.uk/support/en/product/KDL-32W5500/manuals. I have got to convert them into something, e.g. mpeg2 to be able to play on the TV via twonky. All our DVDs convert fine using pal-dvd, so what is one to do, but repeat and rinse for BD MKV files?

Please show me...

How about a different method?
Use dvdfab to copy BD to hard drive.
Use BDRebuilder to convert to dvd.

Could this be a streaming issue? Is the bitrate too high? Also are you streaming wired or wireless? If you are wireless are you on wifi g or n? It should be n if you are working with high def video.

I'd try cutting one of your bd conversions into a smaller file and try streaming that. It might stream better if its a smaller file. if it is it might indicate a streaming issue and not an actual file issue. But it could also be a bitrate issue. It might not like really high bitrates.

Could this be a streaming issue?

I dont think so. Yes, the TV is wirelessly connected to the router across the room, but I can stream 5GB DVD mpg files perfectly fine, unless of course downmixing a BD (~25GB) to DVD (~5GB) quality somehow puts extra load on a wireless connection? I dont think so

Remember, I am trying to reduce the quality of the BD to that of a DVD. I have already tried streaming a 25GB mpg BD file across the wireless network and it does indeed struggle fairly rapidly. So the other option, is to downsize the BD to DVD quality, hence reduced filesize, and as I already know that the 280 ~5GB DVD files I have processed so far will play fine, so the process should work.

I cant dig up the wooden floor or have a cable across it - read wife. I was hoping that I could rip the BD film into an MKV (using makemkv as its point and shoot), then re-encode it to mpeg2 format (the only format our Sony DLNA TV client understands).

I tried DVDFab, getting the BD into an MKV, then using ffmpeg with -target pal-dvd. This worked on a small file but not on the full film, which still suffers from stutter. The small file was different m2ts stream form the main film, if that makes a difference
