DVD-RB - Input movie file

[steptoe]

I know this has been covered in the past, but as DVD-RB is 'in stasis' can the option now be added to allow a video file as the input as an alternative to a DVD structure


I had a look if BD-RB allows for a movie file input, which is does, but I understand it outputs the BD disc structure only which won't play in a standard DVD standalone


Thanks

If DVD-RB doesn't have the capability, you can use multiAVCHD instead to convert most video files to compliant standard DVD format...

That's incorrect. First import, then run the job - the output will be BD compatible ( unless you select one of the alternate output formats). That's the while idea of importing.

One of the alternate output formats is DVD format.

Many thanks, I did find the DVD output and after reinstalling the codecs given on your website after constantly getting encode error fails everything worked perfectly first try and everytime on other encodes to DVD-5


Problem is now, the output is slightly blocky compared to the original blu-ray rip, I can see it on various scenes. Its not much but its there on the edges of animations from Disney films, but I would have thought resizing from 1920x1080 to either PAL or NTSC sizes should keep the final quality pretty high

I want to try a different resizer before I consider the the blockiness is caused by bicubicresizer()

Is there a way to change the default resizer to either laczos4resize() or the spline64resize() to see if that fixes the edge blockiness I can see

I've tried changing the resizer in the main .avs script after building the files, but its automatically changed back to the default and can't seem to find anything in the .ini files. Its also mentioned when you try to add external script commands to avoid resizers

I assume this is as its already been resized, so your actually resizing it again


Thanks for any reply

I don't think Lanzos or Spline is going to improve your picture over Bicubic when you are lowering resolution. Their advantage is when you are increasing size. If it is blocky it would be much more likely that it is a result of bitrate limitations and MPEG-2. If you haven't done so, I would suggest you add this to your Config/INI file:

HC_PROFILE=BEST

The default is "NORMAL" -- so you should see a better picture, but you may also see the encode speed slow down.

Resizing from HD to DVD can get complicated if you want optimum quality. Here is a script from TheSkiller:
#scaling, here is a suggestion specifically for HD to SD

Sharpen(0.5, 0) #pre-sharpen horizontally to better keep hor. details
BlackmanResize(704, 576, taps=4) #for AviSynth versions before 2.58 use Spline36Resize
Blur(0, 0.6).Sharpen(0, 0.4) #mild vertical low-pass

To use this script you will need a conversion software which gives you full control over your AviSynth script.

I am not familiar with BD-RB so I do not know if you could specify to use a script like this. If not, I would recommend AVStoDVD...

manolitoYou could just add those lines in the filter editor. But having done many conversions from BD to DVD with BD-RB -- I don't think they are needed -- and the resizing is already built into the conversion. My own experience is that the output from blu-ray to DVD using BD-RB with the default settings is as good or (usually) better than a commercial movie on DVD.

I agree, most of the conversions I've done bd to dvd and I had the opportunity to compare seemed better than the original dvd, always using HC_PROFILE = BEST.
AVStoDVD~BD Rebuilder > HCenc ;)

I did have the 'best' setting. Its all I use, and looking at filters downsizing is not the same as upsizing
