reencoding a DVD to 1080p-sized video

[jarthel]

It's been a very long time (6 yrs?) since I have used something other than CCE/hcencode so it would be nice if someone could give me some tips on how to achieve what I require.

I have some music videos here and currently I have ripped the DVDs into my HDD. I want to convert them to 1080p-sized videos (avi? avi was the last extension I used many years ago)

I want to retain the audio in its original format. And the audio could be in AC3 or LPCM format.

1. what codec to use?
2. do I need to use Avisynth? I hope I can so I can play around with filters.

Thank you very much for the help :)

upscaling does not give more details!!!

Like Atak_Snajpera said, it's pointless to upscale from DVD to 1080p (or variants thereof). You're only going to waste bits, and the end result will look no different than your standard DVD upscaled by whatever software or hardware player you're using on an HD TV/display.

You're better off keeping them in their original resolution and use aspect ratio signaling, or resizing to 1:1 ratio (720x480 --> 640x480, 848x480, 848x352). You're only going to waste your space on your hard drive and have practically -nothing- to gain at all.

well...... if his output device (or device that's scaling) really REALLY sucks at scaling, this might do better. but yeah, definitely a waste of time and space. if he DOES do this route, he should scale to match the output device's native resolution at 1:1. but i think this thread belongs in a diff forum...

deinterlace (if needed) -> lanczos3/4resize(x,y)

Exactly.

If you even just used AviSynth to resize and clean / sharpen / add grain, you'd get better results than some terrible hardware scaler.

Post a source?

Actually avisynth can do a better job at scaling then most hardware players, but generally the benefits of doing the scaling yourself do not outweight the disadvantages.

[Blue_MiSfit]

Indeed. AviSynth can do a better job in most cases, but very very slowly :)

Sure you can do a NNEDI(dh=true).TurnRight().NNEDI(dh=true).TurnLeft() but it's still going to look crappy, even with grain ;) Still not a good idea to encode SD as HD, as the benefits are too minimal. If you want, take a 1 minute clip from a DVD and encode it. Then encode the 1 min clip again but upscale to 1080p, apply some LSF() and AddGrain(). If you're watching this on a TV, the differences between the two should be very small. Especially depending on how far away you're sitting from the TV and how large the TV is.

let me tell u this
i did convert some dvd files to1080p format w/bd structure
the quality is very good
i did convert to avc but the bit rate is very small 13kbps
i did convert mpegs quality is same with higher bitrate

i would say its worth it if the original dvd is superior quality

but let me warn u i have a quadcore processor it took arund 2days roughly but its worth it

The upscaling scripts for avisynth get improved quite regularly.
When compared to a year ago the difference now is incredible.
As mentioned before some scripts beat some commercial hardware upscalers.

The best part is that this can be done in real-time, even on relatively old CPU's.

You are better off keeping the DVD's as is (or maybe remux them to MKV) and then apply the upscaling script during playback(using FFdshow).
This way you can instantly start using it on all your media and when the scripts get improved again you only have to update the script and all your videos get improved.
