the script and the small bitrates?

[guada 2]

Hello,

I noted that a script is very useful to have a picture of quality.
Why one would not work on several filters to optimize the clearness of a video at the same time, especially on small bitrates?

Thank you to clarify.

I don't understand your question. Please explain it better.

Hello Neuron2, :)

To get a picture of quality, the professional uses a lot of filters and others.... it is the case of the Mpeg-2 compression.

I noticed that one could increase the quality of a DVD with scripts (use of precise filters).
Why one could not do it on movies with the format of compression Mpeg4 ASP or AVC, with very low bitrates.

Do you understand to me now?

You mean you want to have DVD quality on low bitrates ?

" You mean you want to have DVD quality on low bitrates "

No, no, no, no, no.

I would like that one uses this technique (of the professionals ) on the Xvid codecs, Divxs or x264, but with small bitrates.

Sorry but most good looking DVDs use excessive bitrate to get good quality (unless the source compresses well) and there is a lot of manual tweaking involved during the mastering process.

If you want to do what most people already do here -> slightly denoise / degrain (etc.) in order to make things more compressible than you need to read up a bit. Same is done in broadcast - unfortunately it has gotten very bad over time.
It just wasn't enough to smooth pictures to total softness they also started reduce resolution to 544x576 and so on - just to save bitrate and pack even more programs on a transponder / frequency.

I disagree that this technique that 'professionals' use is something worth redoing if you aim to create high quality encodes. I prefer a slightly noisy / grainy picture over a totally smoothed picture - it gives me kind of a feel that any 'soul' or 'life' the image ever had has been ripped away from it (picture is perceived as very unnatural).

Unfortunately there is no magic solution that will for ex. make the picture sharper and also require less bits (though there are constant improvements to codec efficiencies). If you like the quality sharpeners like LimitedSharpen produce (which IMHO improves perceived quality) than you'll also have to pay for it with a few more bits.


/EDiT I just reread your posts if you mean reencoding from sources like XviD or just improving their quality on playback - you can resort to all kind of postprocessing functions available in ffdshow.
If you mean to create scripts to encode to low-bitrates while keeping good quality - you'll have to somewhere drop something.. either lower audio quality, reduce video resolutions, denoise the source etc. etc.

Your reasoning is not false.
I believe that I would think of twice, and I would follow your advice.

Thank you very much communist.
