I am currently capturing a PAL analogue source on my hard drive recorder, then burning it to DVD.
I rip the DVD on my pc and run it through the KDVD templates for CCE by Vmesquita.
I have been playing around with various scripts today but to be honest I really don't know what I am doing.
I have chopped together bits from various people scripts and managed to get about a 22% reduction in file size.
I started with this:
Quote:
LoadPlugin("C:\PROGRA~1\AutoGK\DGMPGDec\DGDecode.d ll")

movie="rawpt1.d2v"
sound="rawpt1 MPA T01 DELAY 0ms.mpa"
video=MPEG2Source(movie)++mpeg2source("rawpt2.d2v" )++mpeg2source("rawpt3.d2v")
audio = DirectShowSource(sound)++directshowsource("rawpt2 MPA T01 DELAY 0ms.mpa")++directshowsource("rawpt3 MPA T01 DELAY -120ms.mpa")
audiodub(video,audio)
#copy trim from video avs
trim(2957,15016)++trim(19576,32250 )++trim(41774,60609)++trim(66092,74146)++trim(7871 3,82517)++trim(85075,85874)++trim(91103,93086)
++trim(93252,104043)++trim(110133,124310)++trim(13 7267,147385)+trim(152919,157485)+trim(161495,16396 6)
+trim(169857,180627)+trim(185184,199940)
SelectRangeEvery(1200, 12)
|
This gave me a 29.5 Mb file.
Currently I am doing this:

SelectRangeEvery(1200, 12)

Which has given me a 23 Mb file.
The trims are to get rid of the ads etc.
The SelectRangeEvery is to give me 1% of the frames to test on.
Anything else I can do to improve it?
Thanks in advance.

VMesquita templates were inspired by one of my old script for avi -> kvcd jobs. You give a look to last one and update that part of your current script :

One more really stupid question.
When you say last one do you mean the last on in the list or version 4.
They are numbered backwards.

A harddrive recorder already uses a non optimal compression, and even when targeting a single DVD-R using the harddiskrecorders internal comprssion will result in a Picture which is anything but not good for a recompression via CCE or whatever.
My 2 cents, do use your harddrive recorder capturing at highest possible quality and keep the capture on its internal HD. If possible do connect your harddrive recorder to the pc and try to access that data from the harddrive recorder (is it possible like if connecting to an ext. Harddrive?).

As said in top of the message, the old version are given for historical reason, but latest is V4

Last Recoders have a 400 GB disc and a "HQ+" recording mode that is a CBR at 15 MB/s.

YEP, but he said that he captures, burns it ta a DVD-R and on the PC that DVD-R Content will be reencoded So I dont think that this HQ Quality on the HD at 18Mbit/s will be on a HDrecorder-burned DVD-R

Yup, must read first post later.
I'll let you know how I get on.

Can't connect it to the PC, well not easily anyway.
I can burn my DVDs at the highest setting I can record at which works out at just over an hour on a DVD-R.
I have always assumed is was because my source was mainly fast action that I was having probelms with compression.

Not at all. Recoders often use a CBR method for encoding that set the recorded time whatever the source kind.
SP = 1 hour
LP = 2 hours
ELP = 4 hours...

Mine has
Fine - 60 mins
SP - 120 mins
LP - 240 mins
EP -360 mins
With 32 in between settings.
Most TV I record and watch at LP.
The quality is good enough to watch for me.
Sports and fast action I record at Fine.
I used to burn my DVD's somewhere between fine and sp depending on the length of footage.
The only footage I have really played around with is wrestling, hence me thinking fast action was my problem.
Still these filters have managed to reduce my file size by about 25%.
~6 hours on a half D1 DVD-R is in my sights.

These are generally VBR ! Check the manual or your recoder, it should be indicated.

Which min and max video bitrate are you using ?
Note: 6hours on a DVD is okay but not wiht fullscreen footage !

300 and 2500 with Q 40 in CCE.
Vmesquita defaults.
I haven't really started playing around with these yet.
I was just using them as a constant while testing out the filters.

I am recording for a friend and average about 3 hours per week.
If I can get 6 hours on one DVD at a watchable quality I will be happy.
What I have managed so far is better than the 3 hours I was getting using DVD shrink.

Thinks about audio : if the tv show is mono, use mono mp2 at 64 kbit/s. It's far enought.
