Best settings for DVD

Notes

Notes:

• Asking google (handbrake best settings for dvd, etc).

• H265 doesn't seem to bring lot of advantage over H264, because H265 is mainly for highres video, which DVD isn't. H265 is much much slower however.

• Performance: https://handbrake.fr/docs/en/1.3.0/technical/performance.html

Handbrake presets:

• HQ 576p25 Surround: H.264, RF:18, Peak Framerate, Constant Quality, Preset slow, Tune none, Profile high, Level 3.1.
• SuperHQ 576p25 Surround: H.264, RF:16, Peak Framerate, Constant Quality, Preset veryslow, Tune none, Profile high, Level 3.1, more settings ref=5:bframes=5.

Using:

• Starting from HQ 576p25.
• Set Tune to film.
• Set Filters, Deblock, to Light (and tune medium); denoise filter to HQDN3D, preset medium. Interlace detection to Default, Deinterlace to Decomb.
• Audio, select all language, in auto passthrough.
• Subtitles, all subtitles, no burn in.
• Bench: Bad Teacher, x264, denoise, deblock, decomb: 96.99 / 95.70 fps, 2357MB, 1672kbps. But strange artefacts in generic (around statue, also around the text in generic).

Things to try:

• https://forums.plex.tv/t/dvd-rip-quality-on-plex-roku-ultra/172481/12
• Don't use Constant Quality, but a given bitrate, like 1800-2200.
• Check that 720*576 is played ok (no need to go to 1024x576 as said in link above).
• Transcode all audio to AAC (so that to get direct play). Use Stereo only. Use Dynamic Range. Use

Subtitles

• Which subtitle choose?

• All of them, but assuming they can be displayed correctly.

• Subtitle seems to be "VOBSUB".
• Make a test on Plex on Shield.
• Make a test on Plex on Chrome.
• Make a test with VLC.
• Make a test with mplayer.

Audio

• Which audio track to choose?

• VO + French
• Should we take Dutch if available?

• Which codec to use?

• Ideally passthrough is best, but if AC3, it cannot directplay on Shield TV, which is a bit annoying.
• If transcoding to AAC, audio is very soft. Should we use dynamic range? Should we normalize loudness?

Video - aspect ratio

Note:

• 16:9 = 1.77:1 = 1024 x 576 = 1920 x 1080 (assuming square pixels).
• 16.7:9 = 1.85:1 = 1024 x 552.
• 4:3 = 12:9 = 1.33:1 = 1024 x 768 = 1920 x 1440 (assuming square pixels).

• Pixel Aspect Ratio (PAR)

• This is the pixel ratio to use when displaying an image.
• 1:1 means the stored image assume square pixels.
• 64:45 is the pixel ratio to use to change a 720x576 image into a 16:9 image 1024x576 (we have 720 / 45 * 64 = 1024)

• 720x576 is an image with ratio 5:4 assuming square pixel, but it becomes 16:9 assuming pixel ratio 64:45.
• To be displayed on a monitor with square pixels, then the 720x576 image must be stretched to 1024x576 image to preserved the final image ratio 16:9.

• With 720x576 image,

• a 16:15 PAR gives an image aspect ratio of 4:3.
• a 64:45 PAR gives an image aspect ratio of 16:9.

• Which aspect ratio?

• DVD PAL is always 720x576, but handbrake automatically crops to remove black edges.
• So resulting image cannot simply be panned to fit say 1920x1080 (16:9) display. The best fit must respect the desired aspect ratio.
• In addition, some DVD does not document the aspect ratio correctly.

• Ask Google to get correct a/r (final cut dvd aspect ratio, bad teacher dvd aspect ratio).

• For handbrake, we have to define:

• Storage geometry, the size of the encoded image, which is the size of the source after cropping.
• Display geometry, the size of the image to be displayed on screen, which is the size of the source after cropping.

• Examples

• DVD Final Cut, 1998

• Internet lookup: release ratio is 1.66:1.
• This seems like a bad DVD rip. Viewing the DVD shows an image ratio of 4:3.
• HB detects an issue with PAR: Video PAR 16:15 (ie. 4:3 image) != conainer PAR 64:45 (ie. 16:9 image). It defaults back to 16:9
• HB detects image as 720x576 with 12/14/14/10 autocrop, ie. 694x552, image 16:9, PAR 64:45.
• To correct the image ratio, we remove all crop (to keep the bar / pillar, which seem to be intended), and set the display geometry to 956 x 576.

• DVD Bad Teacher, 2011

• Internet look-up: movie aspect ration is 1.85:1.
• HB detects image as 720x576 with 12/12/0/0 autocrop, ie. 720x552, image 16:9 PAR 64:45.
• HB sets encode size at 720x552, and display size at 1024x552, with standard PAR 64:45, which gives the correct ratio 16.7:1, aka 1.85:1.
