The VideoLAN Forums

Firstly I would like to say how much I love this program I use this all the time over Windows Media Player however I feel it lacks many useful video enhancements.

De-interlacing - is too basic it needs bob, weaver, or single field I've always found blending frames for certain clips blurry which is why I would prefer dropping one of the interlacing fields.

Temporal noise filter - this is a technique used to remove fluctuations in pixel colour I find it greatly reduces the noise patterns exhibited from analogue video capture like VHS or TV Cards (composite / S-Video).
Not only does it improve the viewing experience it also helps to increase the image quality for fixed bit rate video encoding / streaming.

Smart Brightness - provide AGC to lighten up very dark scenes in videos and maybe reduce the brightness of bright video scenes.

Sharpness should be applied after de-interlacing not before - when applying sharpness to interlaced video while de-interlaced "blend" the sharpness feature seems to over enhance the interlaced lines making de-interlacing ineffective and ugly.

RGB control or white balancing for video clips - indoor video footage usually appears reddish / lacking in blue or maybe a video clip has too much green it would be great to be able to balance this back without having to resort to video editing software.

Smooth blocky video - squares can appear because video bit rate is too low or too complex within a given bit rate target. It would be nice if VLC could detect these areas and smooth them out. I have a plugin for VirtualDub that does just that however implementing something in real time would be amazing.

Settings presets - any colour corrections or enhancements would be useful if saved / loaded as presets and perhaps individual video clips could have their own presets.

A-B mode - looping a certain portion of video.

De-interlacing already has multiple modes which I believe covers all the options you mentioned.

Discard, Blend, Mean, Bob, Linear, X, Yadif, Yadif (2x), Phosphor, Film NTSC (IVTC)

Ahh yes you're right I missed that option from the menu I was tapping "D" on my keyboard I assumed it was interlaced blend or no interlacing.

Temporal noise filter: What you're looking for could be implemented with a more advanced de-noising filter. If you see a video filter you're interested in seeing in VLC, please let us know! Maybe we can't implement it for some reason(wrong programming language, proprietary restrictions apply, etc.), but if you think it would work, it's worth submitting.
Smart brightness: This idea has been tossed around for a while, but it would be very hard to implement from scratch. I know that lots of televisions implement this feature, so if you have a television that does this, then maybe you could provide us with some technical specifications and this can be worked out.
Settings presets: This feature has already been implemented in the open-source media player MPlayer. If you are using Linux, it should be easy to find a source-code package for this programme. Then, if you can find the codefiles that might deal with this, you could send them to us(legal with open-source, as long as they have a document containing the GPL and stating proper credit). This would be a lot easier than doing this from scratch.
