AutoRV10 - FAQ

AutoRV10 - FAQ (Frequently Asked Questions)
<< some sentenses are extracted from doom9 guide >>

What is exactly the AltCC (Alternative Curve Compression) ?

The AltCC is an adaptation for the RV10 of the old Curve Scaling function of the Xvid v0.9 it's an alternative of the internal linear scaling. It *sometimes* produce better result, and it's an exclusive feature of Autorv10

What are the params in the AltCC option ?

Auto Calculation : calculate the high and low % from average frame size by analyzing the first stat .pass file.

The params (Light / Medium / Strong) are some thresholds to compute these % :
- Light => count all the frames in the calculation.
- Medium => ignore some "unnaturally high" framesizes
- Strong => exclude more frames.

For example with a short sample you have these values :
- Light => 600% / 250%
- Medium => 300% / 200%
- Strong => 250% / 190%

These high/low distance % are used in the bitrate redistribution, Lowering the low distance will move the preference towards low bitrate frames. Raising the high distance will move the preference towards high bitrate frames.

Curve aggression defines how quickly the codec adapts bitrate to frames.

The params (Slow / Medium / Fast) are the speed of bitrate redistribution.

A fast aggression will help the codec aid low bitrate frames while hurting high bitrate frames and is better for very dynamic scenes (i.e. a slow motion scene, then up to a lot of motion very quickly). Slow aggression adapts slower and won't improve low bitrate frames as much, but will not harm high bitrate frames much either.
Medium aggression is a compromise of the two.

Bitrate payback delay is how many frames (the window) the codec has to react to over/underuse of bits.

What is an HD (High Definition) Encoding ?

an HD encode is an encode with an high bitrate > 3000 kbps and generaly with an high resolution (for exemple 1280*xxx).

Any advice or tips for HD Encoding ?

here are my personnal sttings (i can't take responsability ) for HD encoding :

** Use anamorphic resize (keep cropped resolution) [be sure you crop values are not ODD]

** If you don't use anamorphic resize think to use Lanczos filter resize for a sharp resize.

** Video mode = "Sharpest Motion" (Default Settings).

** Perhaps a ligh xsharpen filter to improve sharpness.

** Removegrain filter generaly doesn't harm.

[** use kerneldeint for IVTC/Deinterlace if needed, it keep a sharp result.]

** EHQ = 100 / highter EHQ for first pass.

Can i backup my RealVideo file on DVD (4489 or 4680 MB) ?

Unhappyly for the moment there is a limitation of 4Gb for the .rmvb file

Is there a solution for this 4Gb size limitation ?

YES in fact if you enter an output size bigger then 4Gb you will obtain as final file 2 file :
realproducer will split the final file in 3.9gb parts and add a number at the end of the name.

the solution is to convert the RMVB (realvideo) file in a MKV (matroska) file.
following this process :
- convert the .rmvb in .mkv file with mkvmerge/mkvmerge gui v1.4. to do this, join the .rmvb files using the "append" feature of mkvmerge gui v1.4 and mux the audio.

Is there some limitations in the "EndCredits" option ?

"Rmeditor.exe" (RealMedia Editor) is used to join the movie.rmvb and the credit.rmvb part, but this software was not really updated since rv8 and have some limitations.
It will failed in the 2 following case :

- You can't use them when you create some backup with an output size upper than 2 Gb.

- if you have some foreign character in the file path (example : "","" ..) it only work if your pathname is in US-ASCII.

Bad sound with Audio Multichannel Codec in Realplayer

It's because you don't have a 5.1 audio card/speakers normaly it's DirectSound who was supposed to downmix each channels to work on a 2.0 audio speakers.
You can solve this issue using the following tips :
in RealPlayer, Tools->Preferences->Hardware->Sound Card Compatibility (Settings...), check the box for "Disable Direct Sound".


Still Under Construction !!!
