minimum re-encoding mini dv movies to create blu-ray playable on player

[Jean88]

Hello,
I have several mini-dv movies capturing from a mini-dv camcorder (video 720x576, 4:3, 24.4 Mbps, 25fps PAL / audio:1024 Kbs, 32KHz, 2 channels PCM). I keep them safely.
I want to make blu-rays with menus with those movies so that it is easy to watch them on a blu-ray player in the living room.
I would like to know wich software I should use, and what format configuration I should set.
I don't want to loose quality, neither to upscale to HD, neither to compress if not necessary.
If not necessary, I do not want to re-encode. But if I have to re-encode, I would like to do it as little as possible. I do not mind the size of the file, I have lot of blu-ray.
I would like to keep the same video quality as now when playing those miniDV file on computer.
How to burn blu-ray with mini dv movies with minimum re-encoding ?
Thank you very much for your help

Jean

You could try multiAVCHD

But others here may have better suggestions.

You have to reencode both the audio and the video. DV-AVI isn't compliant, and neither is 32KHz WAV audio.

the least painful way to go is to convert to dvd. it's 4:3 and it's also probably interlaced, so keep it that way. the audio was recorded wrong, 32khz was only meant for 4 channel. it should have been 48khz if it's stereo, but most editors should be able to convert it to 48khz ac3 2ch. without too much trouble.

Believe it or not, there was a part of the BD "recording" spec that specifically supported DV material. Unfortunately, AFAIK, there are no known/existing consumer players that support that part of the spec.

First thank you so much to every one who help me.
So I understood that i have to reencode. I want to use blu-ray double layer in order to minimise the number of disc.
I have tried multiAVCHD but it goes through the reencodage function.
Which output format (input format is video 720x576, 4:3, 24.4 Mbps, 25fps PAL / audio:1024 Kbs, 32KHz, 2 channels PCM) should I set so that in order to save reencoding time ? The quality should stay the same.
If I choose the x264, should I use 24.4 Mbps as bitrate to keep the same quality ?
Must I convert 720x576 into 1920x1080 in order to play at full screen on the TV ? Or the player will upscale itself (The TV is 1920x1080) ?
Thanks a lot for you help

it's never going to be full screen if it was recorded as 4:3 dv. there must be black bars on the sides.

[Jean88]

Yes, you are right, I was not clear enough. I mean that I would like that the height size of 720 line becomes 1080 line without upsacling by computer if not necessary. Of course, there will be some black bars on the sides.

To be practical - while encoding miniDV to get same quality is impossible. The trick is to encode to the quality that watching the screen gives you visually almost no differences or very little differences. Choose CRF 16 or 17 that might be good enough. The lower number the better quality but volume increases, so you find a sweet spot for your needs.

If you are really concern and want higher bitrates , where video has dark scenes, low light or gradients that tend to create banding (what you can see on Netflix and other streaming sites, like those banding halos around a light source in the dark etc.) you choose CRF very low, lower than you normally would, you could also cut off max bitrates, for miniDV video perhaps 10.000kbps. Makes little sense to encode bitrate over 10.000kbps for that low resolution. Doing that you increase overall base for bitrate and also prevent distributing too much bitrate ( where not needed). But bitrate seams no concern for you so you can use a very low CRF and that's it.

make sure you keep video interlace, do not deinterlace and keep resolution the same, 720x576

Your Blu-Ray player or television will take care of that. The 720 width will become 1440 (with black pillar bars added to pad out the rest) and your 576 height will become 1080. Your television is incapable of displaying anything but 1080p.
