![]() (Storage) aspect ratio x Pixel aspect Ratio = Display aspect ratioīut if you resize (note, you cannot resize interlace footage, but if having progressive), if you resize to square pixel resolution, like 640x480, you do not put -sar xxxxx in x264 command line, no need 4:3 PAL DV avi has different SAR, NTSC widescreen as well etc, all values take from here x264 encoder can place that flag into h.264 stream and media players (hopefully) follow that flag. MBAFF works fine on every machine I have used.Ĭan you please briefly explain why you recommend using the following 4 setting "-sar 8:9 -tune film -vbv-bufsize 15000 -vbv-maxrate 15000" in your sample x264 command line for DV->MP4 conversion above? -sar 8:9 DV avi is anamorphic video, 4:3 NTSC DVavi is stored within 720x480 but if you put it on computer screen medial player resizes it to 4/3 ratio, 640x480, 640/480=4/3, There is a flag within DV stream that media player follow to show proportionally 4:3 on screnn, any resolution but 4:3. Thanks I have no issue.and used it before I had a 60p video camera. ![]() Do you have in mind a particular issue with MBAFF? And I didn't even notice any slowdown from interlaced encoding, plus that wouldn't be a big deal for me anyway. I tested interlaced encodes done with VidCoder (x264) on a couple of devices including my Sony BDP-S5100 player, and they seem to play fine. Ron spencer: I am certainly not an expert, but google told me that MBAFF is a way of encoding interlaced (used by x264 and many other encoders), and is actually more efficient than PAFF, with the only potential downsides of lower compatibility and slower encoding. ![]() Do you think other x264 GUI front-ends would also have the color blurring issue for interlaced H.264 that you mentioned for Handbrake?Īn aside question, is changing from medium to slow preset going to produce practically the same perceived quality, but squeeze the file size / bitrate a bit more by spending more time to improve encoding efficiency? AviSynth is not really in my comfort zone, more like a last resort, so would prefer to stay with GUI and combined video/audio encoding, unless there would be a material quality improvement for interlaced H.264 from doing it the other way. ![]()
