Removing or reducing pixelation

[CM120884]

I have several clips i am editing. Some of them are more pixelated than others. Is there any program/software that exists that can either remove part of or all of the pixelation?

Use AVISynth with Deblock_QED(). Increase the strength as needed.

I don't think anyone has any idea what you mean by 'pixelated". Do you mean block noise (macroblocks) or pixel breakup? Macroblocks are usually a sign of over compression (low bitrate unsuitable for the type of video you're working with), for which filters like DeBlock_QED and the original DeBlock are recommended, along with filters like dfttest used with 16-bit settings. The stronger you make the settings, the more they'll soften your video.

Deblocking will replace rectangular blocks with smooth gradients and may remove some true detail. That may not be an improvement. It depends on the source and what you prefer.

I think its macroblocking. Is there anything i can do using a video editor that might help reduce it?

Look for the built-in deblocking tool?

Some video decoders have optional deblocking filters when they decode. Xvid, for example. h.264, h.265, and most other new decoders have deblocking filters built in. Mpeg 2 and other older decoders don't have deblocking. With those you have to use external filters. The aforementioned deblock_qed() is an AviSynth filter -- AviSynth is a script driven filtering system. Maybe you should provide a short sample of your video that shows the problem (don't filter it or reencode it).
