I haven't had the time to test yet (I hope to try soon enough!) but it looks like you are onto something. Crafty's footage does not look interlaced, however in lower res (which one should expect, I guess! - it would propably require a bit of tweaking to make it perform well). It looks like a work-around rather than a perfect solution, but still - as an option it seems to do the trick!
Both from the GH2 (if that's what you mean?) with Gopstoppa patch. Set it up on the tripod, focused on the sound DVD, recorded a few seconds in 24p movie mode, stopped and switched to 50i mode and recorded a few more seconds, loaded both clips into Premiere and took screen grabs.
You see when you normally open up a PAL recording from Stock GH2 in streamparser it asks you 'Is this a native 25p stream?' If you answer yes you get Mode=1080/50i1080/25p W(50i wrapper), if you answer no, you get simply 1080/50i. Which is correct.
With the GOP1 patch if you answer yes to 'Is this a native 25p stream?' you get Mode = 1080/25pH (Native Hack) and if you answer No you now get 1080/25pW (50i Wrapper). So something is definitely playing up!!! But it may well be to do with GOP1 and a few encoder settings Im playing with.
Does it make use of all the pixels, or does it just skips every second line? In short: Can it be in any way compared to 24p? The settings you are talking about is in post, not in cam? So it will just spit out p in i container?
@Driftwood "Why don't you run a simple test - use a tripod and record a static scene in 24P, 25P and also 50i" Could you explain me how can I record in 25 P with my GH2? Where is this option? I can't understand it Sorry for my poor english.
I mentioned in the first place it could be a false positive... but you never know. :-) Especially as there are a lot of cameras out there doing 25p in a 50 wrapper using 25PsF
Cus Im doing some intensive encoder settting tests at the moment. I was hoping (and I did ask this days ago) if someone would test it. Alas, it seems people arent that bothered about getting 25p!!!!
Why don't you run a simple test - use a tripod and record a static scene in 24P, 25P and also 50i. Examine the footage. First compare the 24P to the 50i. The 50i should have less vertical resolution. Now compare the 25P. Which one does it match? And you'll have your answer.
@Driftwood Are you sure that is'nt a false positive? You can get a 25 p in a 50i wrapper stream only with GOPSTOPPA patch or with other ones also?. If so, what is the reason to get this great setting only with GOPSTOPPA? Many many thanks for your great work, Driftwood!!
GOPSTOPPA patch - released a few pages back on this thread. Well so far ive brought it into Premiere Pro on the PC side - cant switch to mac whilst testing with this hackintosh :-) and all seems good. Record on 1080i, open with streamparser and you get the choice Native 25p hack or 25p W in a 50i wrapper. All well and good. Proceed to PremierePro. Import mts file into PP, immediately it recognises it as 25p (no interpretation required. Place it on a 25p timeline (remember its still in a wrapper) so it will go red on the the 25p timeline. Export out and its a very good 25p - so it seems. Now as I dont shoot much in 25p anymore I need some of you guys to further test this out on other NLE's etc...
My tests report that 25p in a 50i wrapper seems to work ok from my latest 'GOPStoppa' GOP1 patch. For 25p in 50i clips (aka 25PsF) set the Field Order property to None (progressive scan).
