AviSynth colorspace support is quite limited, fortunately most common JPEG formats are natively supported in AviSynth 2.6 (Y8, YV12, YV16, YV24 and YV411).

			Remember that JPEGs use PC levels, Rec.601 colorspace and [[Sampling#mpeg-1_versus_mpeg-2_sampling\|MPEG1 chroma position]] ''most'' of the time. Sadly, there is no way now for source filter to provide such information and you'd have to set correct parameters manually when converting to other colorspaces.

In addition, JpegSource has an optional reconstruction pass that can only be done during the decoding stage. This process can accurately suppress common JPEG artifacts (blocking, ringing/mosquito noise, etc). The reconstruction pass is harmless on high quality JPEGs but can produce excellent results on highly compressed JPEGs. This technique yields better results than other post-processing methods.
