I can't testing 1920 mode setting, because don't have fast card.

I can't testing 1920 mode setting, because don't have fast card.

Go and by good fast card. Transcent Class 10 is quite cheap and looks good.

1920 mode do not require fast card (with defailt MJPEG settings, you can further decrease quality, btw), but must be used with 30-24fps patch.
Image is really weird magenta-green and distored.
Whole patch purpose was to prove that MJPEG encoder is capable to produce 1080p24.

And look at actual table values (see my second post at first page).

[NURBS]

Okey, thank you for note about digits table. ;-)

[Vitaliy Kiselev]

Okey, thank you for note about digits table. ;-)

Testing must be the following:
1) Shooting very low details image (white paper, etc).
2) Shooting medium detail, out of focus image.
3) Focused normal interior image.
4) Glass, trees, very high detail images with good lightling

For each of four scenarios you must make separate clips. And one clip with all this together.
So it'll be possible to understand how it works.

[NURBS]

Very interesting deal.

SD video DV compression is 25Mbit/s - Mjpeg
HD 720p Mjpeg 50Mbit/s it's very near same compression level.

My Sandisk can write 9Mb/s (70 Mbps) :-) I need new card..

;-) very nice result!

[Isaac_Brody]

Wait, if I'm reading correctly 1080P mjpeg works? Is this with pulldown or native 24P?

[sirk]

I don't get this:
the quality settings are "for 1080p30 only" but you provide an extra 1920 patch?
did you change the standard mjpeg 720p setting to 1080p? why the extra 1920 patch?
thanks

Dont know what QF means (first use of this tool called MediaInfo Mac). Hope it helps.
PS: its 720p. Why does it say "only for 1020p" in the description in ptool?

The mjpeg developments are great news. If 24 FPS could be achieved with 720p and maybe even 1080p with the better bit rate, etc. it would be fabulous. I like the stability, quality and easier post production of mjpeg. tester13 YOU ARE GOOD AT YOUR GAME!

[Barry_Green]

If "real" 24fps mjpg were possible in 720p mode, with enhanced bitrate that would be delicious. Absolutely mud-free, great-looking hd at 24p...

I am praying for that. The GH 1 with that ability would be awesome.

So it doesn't seem that it is clear yet, whether or not the 24p MJPEG is still skipping frames or not...right?

Latest report it was but tester13 was concentrating more on bitrate and and stuff at this moment. Barry, if the Nikon D90 does 720p24 you think it could be possible to achieve it flawlessly on the GH1 with a hack? If anybody can do it tester13 would be the one!

Ok noob question here. Might be the dumbest questions but....What advantages will I have if I use the latest firmware? what disadvantages? Is there a how to on the pages here? I bought my Gh1 last feb and did not do any updates to it...should I have done so? I still don't have a pulldown program.....Should I buy a pulldown program or should I wait till a video editing program puts the pulldown into their product? If I do have to buy one....what program would you guys recommend? I know these are allot of questions but I know there is some of you out there that can answer all of them. Thanks

Best to start a new thread for these questions.
