Agreed - I've never wanted to use H and L, but they could be handy now - say set to 25 and 17 or 17 and 13.

jobless, have you shot in H or L mode to confirm they are not affected by AVCHD settings? It is just hard for me to believe AVCHD settings would only affect FHD and SH mode but not H nor L mode. If that is true, there must be other variables that control H and L mode.

If you are shooting 24P, why would you be using Cineform Neoscene, which is partially a De-interlace program? You can Log and Transfer the 24P material right into FCP. The only issue is the 23.971 frame rate and the field dominance thing.
From the tests I did on 60i AVCHD footage, between using Cineform Neoscene as opposed to Log & Transfer into FCP as ProRes 422 (HQ), de-interlace with JES de-interlacer, the footage that went the L&T to JES route looked better to my eyes than the stuff I was getting out of Cineform Neoscene.
I didn't try to de-interlace with JES the 24P footage coming out of the camera, because I figured "what's the point?" If I have to run the footage through the de-interlace program anyway, might as well shoot 60i.
Best,

You can turn off the deinterlacing/pulldown part of NeoScene. All I'm using it for now is transcoding... I bought it back when you did have to do that with 24p material. But it's nice now as it sorts out whatever issue is happening with the 23.971 framerate & Final Cut.
What were the differences in Cineform vs L&T/JES? Color-related or resolution or something about the cadence?

It was color related and sharpness related. Though both of those issues could now be different with the patches we're testing. No cadence issues that I noticed.
This is from memory because I tested it a while ago, but if memory serves, the Cineform footage looked a bit softer, a bit muddier (not the MUD we've been talking about here, but just a bit darker/softer) and the colors were not as clean. Again, kind of darker, softer, duller. I've been doing this for years and most folks would probably look at it and go "Looks the same to me." I'm just real picky.
Best,

It would be good to have old stable SH mode(17mbps) in H mode.
Curent settings in Ptool affecting 17Mbps bitrate ( FHD and SH) so I suppose that we could only change H and L Modes. I would vote for H-30Mbps ( No mud) and L -- 17Mbps ...

I am having the same problem with Edius, I can drop native 24p in a 23.98fps timeline, no errors, but the motion sequence stops every 4th frame (similar to the original 24p in a 60i wrapper). Funnily though, if I use the Edius AVCtoHQ conversion utility, it correctly produces a Canopus HQ 23.98p file... But this means working with intermediates rather than original files... which is still much better than having to do the pulldown. Hence I am fine so far.

I always thought the Neoscene output I got made some of the "mud" and macroblocking kind of smooth out. i never thought it looked darker or softer at all though.
+1
Especially given that those don't match anymore. Oh, yeah, there is only three to report now.

here here. can there be a post made were *only* these settings go? I keep seeing special named settings but no one ever gives out the numbers Thanks!
Thanks!Well there are a couple different versions of "B" and "D" settings that I've seen mentioned around here.
It might be helpful to also reference line number that corresponds to settings in the Ptool spreadsheet. More people need to input their settings so we can keep an easy to read record of settings that have been tried.
Also, to the member that "keeps" the spreadsheet, can we add another couple of columns to the spreadsheet that keep a tally of "pass" or "fail" so when other people give other member's settings a try, they can report if they worked or not without having to enter in another row of identical information?

Thumbs Up for that.here here. can there be a post made were *only* these settings go? I keep seeing special named settings but no one ever gives out the numbers

Please use the form already provided and fill out what you've tried (this goes for everybody):

Remember folks, these settings are SUGGESTIONS, not perfect settings! We are meant to TEST these settings for Tester13 and report issues back. This has completely devolved into something very unscientific where folks are only interested in getting improvements without actually doing any work I think. We need to stop asking for the same settings and start trying new setting combinations to try to figure out how these various settings work together.
After alot of arious testing, I feel like XDcam deliver better result that my last best setting aka H.264 bframe multipass 100% quality.
Less blocking but a bit less good in black area I think, but no scientific testiting.
Keyframe pulsing
Keyframe pulsing
Barry has mentioned this before, I analyzed some highest detail scenes (with the 38/40/42 AVCHD settings, class 6 card) and I noticed this strong keyframe pulsing, see screenshot below.
Plus, maybe it is my card, on very high detail scenes it drops every 12th frame (although I did not change GOP settings). It doesn't do that on less detailed scenes.
Is this happening to others as well, or is it related to Edius / Canopus AVCto HQ utility?
