AVCSource() + HD input = artifacts

As an HD source, I use AVCHD files made by a camera, NTSC version. No processing is applied to these files prior to feeding them to AviSynth, they are downloaded straight from the camera's SDHC flash card. The camera is configured for maximum quality (up to 17 Mbps) 1080i. It is actually configured with a pretty mild gamma curve ("Cinema" mode) which reduces the noise and eases the load on the encoder. Here's an AVCHD file: The .avs script is very simple: Code:

Coincidentally, I just now sent neuron2 a PM regarding what seems to be the exact same issue. I'm convinced that it may be an issue with DGAVCIndex.

hmm... could be an issue with libavcodec not properly decoding all forms of interlaced AVC... You might have to use DirectShowSource with CoreAVC, since IIRC it handles all types of interlaced content correctly. ~MiSfit

I don't think its a problem with the decoding process, as the artifacts appear once you index the file, and look through it in virtualdub. EDIT: I re-read what you said, and actually, directshowsource looks to be working well. So everything seems to suggest that DGAVCIndex is causing these artifacting problems :eek:.

I *think* CoreAVC does support this. So, you could theoretically get WINE running, install CoreAVC and Media Player Classic. Theoretically :) WINE is not exactly simple.. ~MiSfit
