@From_Paris If there is no reason to use it, if you can read/work with the files natively, then don't use 5DtoRGB it gives no benefits.

@shian Yes, there are older comparisons, it's in one of the earlier closed thead segements of this topic.
Again, it showed Sedna A on top.

@Stray On Mac, I use 5dtorgb or Neoscene to cineform 422. 5dtorgb only for 4444 prores. Otherwise Clipwrap. On NeoScene, there is a lower bitrate on the final file, that leads me to think to a further recompression. But I thought this was the PATCH topic... Shouldn't we stick to the theme?

@terry2 Yep we probably should. However if you are transcoding GOP1 files into another Intra format and your file is smaller then yep, you're most probably losing something. Its quite simple to test really, just do some brutal processing on the native file and exactly the same processing on the transcoded version and compare the results. Most Intra codecs have I-Frames that are a little bit smaller than driftwoods GOP1s, and they also are mostly for 4:2:2 source too (which mitigates things a fair bit). That is of course if you can read the native files with whatever application that you're using. Transcoding 4:2:0 footage to 4:4:4 with 5DtoRGB I reckon would cause more harm than benefit. Seriously, try some footage that has some banding and see what happens to it, thats the best way to test any sort of space upsampling. Anyway, I guess your application pushes your raw MTS footage into a 4:4:4 or linear space anyway, as most do these days. But if you're hooked into a transcoding workflow and you can use Neoscene, I'd go with the cineform product.

@onionbrain If you can convert 24p to 25p without having the sound and footage speed up then i am a real primitive dude because i don't know how to do this..lol But i don't think you were talking about this when you commented but more about using 5dtorgb. Please send me a link on how to use 25p mts from gh2 in premiere pro to have real 25p without using clipwrap or 5dtorgb i'll apreciate it.

@YOSS this is exactly what i do right interpret footage as 25p but you will still get your sound speep up by a semi tone.

5dtoRGB testing is all over the web and has its own dedicated thread in this forum, so why is everyone talking about it here? If you don't want to read up on the tests already performed, then do your own independent tests like many of us do and answer your own questions. In the meantime, please keep this thread focused on patches.

Thanks.

@pinger007

Thank God for the speech police, like you, who prevent this forum from degenerating into meaningful conversations.

As a side note -- all of those comments were relative to Driftwood hacks used with "5DtoRGB." Please kindly refer us to the thread that you approve of that is dedicated to "5DtoRBG" used with Driftwood settings. Thank you.

No need for sarcasm...

There's a thread for 5DtoRGB in this forum which was heavily discussed before you joined in december. There's also several threads at eyepatch films to name a few. Kholi did an excellent job testing the program several months ago with driftwood patches, and his tests can be found here, as well a on his website campcomet.com.

My original point was that we should keep this thread focused. It's inefficient to check for the latest patch updates and see that there's 47 new posts, only to find that they are all off topic.

Just my two cents. If no one agrees, then I'll let it go.

Thanks.

@Onionbrain Well, I won't post it here... but I just did a quick test with Mysteron... and color grading the files directly in Premier led to much more degradation than the 5DtoRB workflow. More macro-blocking in Premire. Brought up more noise as well. 5DtoRGB keeps the nice film-like grain the GH2 produces intact... native Premier grading led to it becoming blocky digital noise again.

I'll put into the other thread later this weekend after I shoot some stuff tonight...

Vitaliy_Kiselev February 15

PTool will be available to core team within hours.

Other important thing is that from now on usage of word "patches" to describe PTool settings will be prohibited. They'll referred as "settings" only.

@bwhitz, I've had the exact same issue. Threw .mts files directly into Premiere/After Effects, played with curves, saw the degraded image quality, converted with 5DtoRGB, carried on with things. I was seeing blockiness and weird color glitches that I've never gotten from transcoded prores files. CS5.5 for both AE/Premiere.

Use what you like but some of us DO see a measurable difference.

@ProAudio4 Thanks for the testing. I wish I saw more posts like that and look forward to examining it when I am home on a better screen.

As for the other thread - given the huge number of posts today, it seems like there may be a call for another workflow thread on transcoding in addition to the ones already there. I hope someone starts one soon and that people learn a lot from it.

When I logged on today, there were over 40 new posts on workflow and I had to read through most of them to get to ProAudio4 and his test. I say that not as a criticism of the discussion, but merely as a statement that it seems to have a life of its own and given that these threads are already so active they close within what feels like a week or less, I think there will be too many posts for people to keep up with if they are both in the same thread. :)

As far as testing, I am doing some unscientific Mysteron vs Sedna shooting tonight and hope to do some more scientific surveys of the settings suggested earlier on Monday.

Once again: last call for non-Driftwood settings suggestions for the Monday test.

Hope everyone else is having a great weekend: I am getting to see friends I have not for 8 years! :)

@thepalalias

is golgop3 w/sedna C on ur list to test?

or anything sedna C?

In this filmmaker's opinion, sedna C is the BOMBBBBBBBBB and wins already..
