Yeah, I agree the 44M settings are really good. I can't stop using the 66M AQ2 settings, but I can't give any decent reason as to why I don't just fall back to the 44M (apart from that one shot I took in a bar in lowlight; you know how it is, theres always that one shot) which are equally as good and have all the benefits you mentioned. In theory the 66M should render motion better, but yeah, how easily do you judge that empirically (I should try and get hold of a metronome). So I'm being irrational, my head says the 44M AQ4 and my gut says 66M AQ2. I think I'll end up with two settings in the end, I'll use the 44M most of the time, and switch to a 66M GOP 6 (if I can get it stable) occasionally.

@towi I didn't think running 66Mbps at AQ4 was stable, which is why Chris took it back down to AQ2 (that and the fact it didn't actually improve the IQ in any dramatic worthwhile way). As bitrate increases AQ can go lower while IQ remains the same is my current understanding of things. Personally I had no problem running the original AQ4 settings, but I couldn't see any real noticeable difference between it (even in post) and 66Mbps running at AQ2.

"Well put @stonebat. As you may have noticed @driftwood and I are approaching settings from opposite directions. We go at each other pretty good from time to time over some issues. It's public, and it's great. Speaking for myself, I've learned a lot from his efforts and our debates - even when we don't agree. Also, I acknowledge that for some applications his settings are exactly what is needed. There is no such thing as "best settings" - it's like saying f5.6 is better than f8, and leaving it at that." cbrandin

I Agree. We're all striving for the best possible solutions. There's always more than one approach. If I'm wrong I have no problems with it.

@olegkalyan Leave them unchecked, it runs at GOP 12 only, so there is no need to change/check it.

Hello. This is my first post. I'm sorry but I do not speak English. I use translator. So they can request funny linguistic anomalies.

I did test a strong color correction. I wanted to see if there is no breakdown of the material. Any noticeable changes in the compression. But it seems that it is very good. Tolerate working very well shot. Additionally, I used a 50% slowdown. I am happy with the result. I work on Avid Media Composer 5.5.

Greet. And thanks a lot for work Vitaliy and friends.

As far as @cbrandin 44Mb settings do we leave gop settings standard in ptools, 12 for 1080 24p/ 30 for 720p?

Chris,
You are absolutely "on a roll" today man!
You're skills, info and help are a great asset for all of us!

Chris>"I challenge anybody to show me where any settings can produce bigger I frames that my 44M settings. I also challenge anybody to explain how even equal IQ can be achieved with smaller I frames, irrespective of P and B frame size."

This is the kind of stuff I like to see!
This is exactly the kind of tests to drive the best quality with reasonable bitrates.

My only concern is the comparison 66Mb/s AQ4 motion frame to HDMI uncompressed motion frame Ralph_B
provided here. I realize 66Mb/s AQ4 static image creates nice quality (healthy I-frames), but 66mbps/AQ4 really loss more detail under Ralph_B's example than I would of expected. Ralph's 66Mb/s AQ2 motion comparison was better. There was still some visual loss in detail, but no where as bad motion compared to AQ4.

If we can just find the "magic" setting that offers the high I-frames for static IQ, but also still holds well for motion.

As you know, one of the greatest complaints from most all video cameras and their compression codecs is the complaint that the image goes soft more than normal when panning. Even the Sony EX series XDCAM had some users complaining of softness during pan. Granted, some of the motion issues are due to the viewing monitor. The lists goes on-and-on from there... I remember my old JVC HD100 - many had the same complaint about motion.

These damn compression formats can be a real bitch! LOL

Thank you
Steve

sorry! ;) Its media composer 5.

@cbrandin
I know what spannig does ;). But if I use the removal from the hack mc5 tries to import every mts clip I shot with te gh2 as if it is spanned. Even if the clip is way under 4gb mc5 imports it and than it starts with a spanned import again and I have to restart the program because it just keeps to show the import spanned clip window. Without the removal its just working fine.

@paglez
Yes I got a eu version of the GH2 working fine if I do not use the 30min limit removal.

No, the spanning issue has to do with what happens when a file reaches 4GB - and that can happen in about 10 minutes at 44M. It has nothing to do with the EU 30 minute limit issue.

Chris

@ cbrandin
Great settings! For the spanning issue try to not use the 30min recording limit! worked for me in mc5!

@Hazna

Here are the 44M settings. There still is an issue with spanning, though. I understand that the 24L settings (they are 32M) span OK for most people.
