Archive DVDs in "acceptable" quality

[rawyolks]

Hi.

I have a collection of tv show, 22 dvds.

It's old, and doesn't look good even untouched.

It's 1987 Married with Children.

I was thinking to passthrough audio and code video in DVDFab 2-pass.

I tried 500kbps, 1000kbps, 1500kbs, honestly the difference isn't much.

What do you think?

I don't want to keep it in MPEG2 - 1 Gigabyte per episode, it's a waste of hard drive, may as well buy a dvd player.

So... how'd you do it?

Cut out a small clip (30 seconds or so) showing steady movement and post it here

Please check both first and last, there's 11 years of difference in technology

I really don't want to download the whole episode, 30 to 60 seconds is enough.
The forum link I posted in post #2 above is a pointer to a post that shows you how to cut out some of your file
not the thread I wanted you to post in!

MWC DVDs were starved for bitrate.

I'm not sure what do you mean.
MWC untouched dvd mpeg2 is so terrible that using high bitrate for x265 coding would be a waste?

Relax, they're only 1gb each. I'll disable sharing of this folder tomorrow ish

I don't know what you find acceptable. This is lower quality than I would encode anything I care about but maybe something like this in AviSynth:

Mpeg2Source("MWC.d2v", CPU2="ooooxx", Info=3) 
Yadif(mode=1) #QTGMC(preset="fast", EZDenoise=1.0, DenoiseMC=true) if you can afford the CPU usage
Crop(6,2,-2,-2)
BilinearResize(640,480)
MergeChroma(aWarpSharp(depth=5), aWarpSharp(depth=10))
Sharpen(0.5, 0.2)

With x264 encoding at the medium preset, crf 23, plus the original AC3 audio, the episode I tested was under 150 MB. You can use a lower CRF to get better quality (and a large file).

The first 10000 frames, video only:

i'd convert to either an iso of the dvd or a straight 1:1 mpeg-2 conversion with no loss of already non-existent quality. if i had to go x264 it would be crf 18 or lower.

Here's an example using ffmpeg in a batch file. You can drag/drop a video onto the batch file to convert it. The new mkv video will have ".x264" added to the end of the filename. For example, MWC.mkv will be converted to MWC.x264.mkv.

"C:\Program Files\ffmpeg64\bin\ffmpeg" -y -i "%~dpnx1" -vf yadif=1,crop=704:572:6:2,scale=w=640:h=480 -c:v libx264 -preset medium -crf 23 -c:a copy "%~dpn1.x264.mkv"

You have to change the path to ffmpeg to wherever it is installed on your computer.

On my computer the full ~23 minute video took less than 2 minutes to convert. Preset medium and crf 23 are the defaults for libx264 but I included them on the command line to make them easy to change for better or worse quality.

The first 10000 frames from the batch file...

Okay, okay. Is it a bad idea to choose x265 over x264 for old dvds?

[jagabo]

In my experience, x265 doesn't have much advantage over x264 with standard definition frame sizes. It just takes much longer to encode.

[Selur]

Main reason for me for x265 with sd is to have 10bit encoding (better compression and banding avoidance) in a main profile and thus better hardware decoding support.
