what is the SD format that have resolution more high?

[marcorocchini]

Hi ****
what is the SD format that have the more width and high (and keep the bt601 colormatrix)? maybe 800x600? thanks

Max SD resolution is 720x576.

or 720*480 for NTSC content

Standard defintion video is also a part of the BluRay/AVCHD spec. You use the same frame size, but BluRay/AVCHD can use higher bitrates than standard "DVD". BluRay and AVCHD also offer a choice of two revised codecs: MPEG as well as h264.

@LMotlow, I think you meant to say: BD includes AVC/H.264 & VC-1 as codecs in addition to MPEG2, and AVCHD uses AVC/H.264 instead of MPEG2.

@OP, 800x600 is never a common resolution for CE-based video. It has its origin mainly as PC-based screencap recordings. As such, it hasn't been governed by CE rules. If you're going to follow CE rules (like the use of BT601 vs. BT709 vs. BT2020, etc.), then it makes sense to follow them all, not just ones you pick and choose. jagabo already told you what the max allowable resolution for Std. Def. material is.

You're right. I didn't mean to imply that both formats use the same encoding, but only that higher-bitrate encoding is available for standard definition BluRay and AVCHD.

Try MPEG-1 - support up to 4096x4096 resolution.

@LMotlow, I agree with you, though I don't think bitrate was what the OP was concerned about.

@pandy, lots of codecs have support for resolutions greater than SD, but again, I don't think the OP was asking about which codec to use, rather something like "what is the max resolution I can get to and still validly use BT601 colorspace?". That's already been answered.

However, knowing the OP's history, I'm sure that won't be the end of this quest. This smacks of another Rube Goldberg attempt to bypass standard apps & methods and to "get something for nothing".

You can use whatever color matrix you want with whatever resolution you want -- if you flag it. If you don't flag it many players will assume rec.601 for 720x576 and below, rec.709 for 1280x720 and above. What happens in between is player dependent.

When ffdshow has to take a guess while converting to RGB, it uses rec.601 when the width is less than or equal to 1024 and the height is less than 600. If the width is greater than 1024 or the height is greater than or equal to 600, it uses rec.709.

That seems like a fairly good "rule of thumb" to me. It means most video with a width or height greater than PAL is considered HD (720x576 anamorphic or 1024x576 in square pixel dimensions). I'm not sure why the height cut-off point is 600. Maybe someone else does. Maybe it relates to scan lines in the analogue era.

I'm not one to shy away from using "non-standard" resolutions, but there's probably some SD/HD ambiguity which I'd maybe try to avoid. I'd be inclined to go for 960x720 or 768x576 etc rather than 800x600 because as a generally rule you'd expect the former to be rec.709 and the latter rec.601.

My point was that AFAIR MPEG-1 support only 601 thus no problem with other color matrices also MPEG-1 is one of widely spread codecs (AFAIR present in Windows family as standard from Win95) thus no problem with compatibility - also results are decent even nowadays thus seem to be perfect candidate for such non standard task.

Second part - i pointed this some time ago - He elevated trolling to unusual level - questions that look reasonable at first time and lot of people really can't say that this is joke! Marco is unique example for smart way of trolling.
