1080i HDTV captures

[laz1989]

Hello all.
I write here because i need opinions from some expert users.
I have some 1080i captures.
example here -> https://mega.co.nz/#!AExDRQTB!OsTlq3wn7ru7v2C5zarRIDxizc5pcv6TjCtXQ6EiPMw
The only thing i want to know,what is a good deinterlacing method,to encode then in x264
I use StaxRip and Ripbot264.
For now i use YADIF,i'm pleased with results but i want to know your opinions.
Thanks in advance

Qtgmc.

QTGMC.
1920x1080 25 FPS progressive is not BD standard.

But 1920x1080 25i is, and it's essentially indistinguishable when wrapping a 25p video, which is why 25p isn't in the BD spec.

Also OP didn't say anything about Blu-ray...

Anyway, back on topic - laz, although you've captured a 1080i broadcast, the video itself is 1080p. No deinterlacing is required. There could be some extremely minor chroma placement issues if care isn't taken, but no-one is likely to ever notice (outside of doom9, anyway!)

Anyway,MPC-HC says at media info this video is interlaced,what sugges to do,to encode in x264 with --no-interlaced option ?

MPC-HC can only report what the container tells it. It's a bit like a DVD of a black and white movie - any media player would report that it's YV12, which is capable of full colour, even though the content has no colour. In this case, the content has no interlacing, but it has been encoded as if it did.

--no-interlaced will probably be just fine (not sure if it's really necessary to force interlacing off, if you're not explicitly enabling it). If you looked really closely, you might see some minor chroma errors, but I'm not really sure what the best solution for that is. Viewers are unlikely to notice, though.

Thanks,very much,i will give a try.i encoded with --no-interlaced and i saw is no difference but i was thinking is my mistake or something.so better to encode whitout --no-interlaced?
Yeah,i tryed without --no-interlaced and seems you are right..i don t need deinterlacing at this type of captures.
Thanks very much for your help.I really appreciate.

I have similar question regarding 1080i tv capture of a football game. I wish to convert to 1920x1080p frame rate 59.94

I have convert similar video in the past but to 1280x720. video was smooth, clear.

when I encode to 1920x1080p same frame rate, the video is a bit jerky, not smooth. Could the experts please explain what I did wrong.

I'm using qtgmc v. 3.364 with all required plugs, avisynth 3.70 and Megui 2507 x32 bit version.

Thank you all

[hippo88]

my qtgmc script was usually "fast", or "medium" and I checked "little noise"

You know what the first question is gonna be, right?
Share a sample ehehehehe

Sounds to me like in both prev posts you posted your failed result,
the guys will not be able to reproduce anything from that, they want source file not failed result.

[hippo88]

I want to encode source file to 1080p but have video played back smooth (play on TV via usb)

it works when encoded to 720p but I have problem with 1080p hence I'm asking experts here for help. Thanks.

Maybe your TV player does not support AVC 1080p59.94 ?

This is Level 4.2 , and many older chips could not play it properly

yeah the tv is from 2010 samsung. I believed I was able to play 1080p 59.94 that I download previously. Let me check.

[wonkey_monkey]

I had trouble at certain levels with my Samsung TV. The solution was to reduce the number of reference frames to 6.

[hippo88]

my megui encoder setting reference frames is set to 3.
