<div dir="ltr">Hi x264 devs,<div><br><div>I'm encoding some animated content, and this scene produces some very bad distortion on the output during a sequence where the screen flashes black and white (frame 55).</div><div>
<br></div><div>You can grab the source file (UTvideo AVI format) and the x264 encode showing the problem here:</div><div><br></div><div><a href="http://mab.to/fr5KCBOTJ">http://mab.to/fr5KCBOTJ</a><br></div><div><br></div>
<div>I've tried this on several different software players, it doesn't seem to be a bug in the decoders (all replicate it exactly). Have yet to burn it to disc and try it on a set-top player though.</div><div><br>
</div><div>Forcing the affected frame to be an I-frame (with "K -1" in the QPfile) does work around the error.</div><div><br></div><div>Command line used:</div><div><br></div><div>x264.exe --aq-strength 0.4 --bitrate 30000 --preset veryslow --tune film --bluray-compat --vbv-maxrate 40000 --vbv-bufsize 30000 --level 4.1 --keyint 24 --open-gop --slices 4 --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --sar 1:1 --qpfile "c:\autovenc\tickets\inprog\scherzo_inferna.avs_ticket.chaps" --stats "c:\autovenc\tickets\inprog\scherzo_inferna.avs_ticket.stats" --pass 1 -o "G:\Authoring\xxx\D1_Shorts\Asset\secondBatch\scherzo_inferna_bug.avc" "f:\scherzo_inferna.avs"<br>
