40Mbps AVCHD High Reliability Patch

I had a bit of trouble editing AVCHD with a dual core. I switched to a core i5, AVCHD 1080p realtime on Vegas !
 
I can edit one native AVCHD timeline in Edius Neo Booster 2.5 with a dualcore 2.3 GHz AMD chipset. Edius Neo Booster 2.5 has an improved AVCHD codec that also uses the graphic card chipset (and costs only 170€ - a lot of bang for the buck).
 
Tanks GMC.

I've read many many posts, hard and software are never a subject. I'll try Edius Neo Booster 2.5.

Is good to know that I can use my Pentium Dual Core 2.8 Ghz E6300 with 40Mbps AVCHD.

Can anybody post other low cost hard and software uses for that rates?

I actually would suggest to use the 1month free trial to see if it works. The trial version has absolutely no restrictions. I also did it to see if it would work with my system before I bought it.
 
I was using the "C" settings and ran into problems filming the side of a small canyon -- lots of detailed rocks and trees. I changed to these settings and everything is working great! And this is on a class "4" Toshiba card!

Thanks for all the efforts.
 
I just knew lpowell would come through for us after reading his mjpeg optimal settings thread :)

I filmed some very close poolside action and got 44Mb/s footage out of the famous Kingston Class 4 cards! "Thanks for all the efforts" from me as well! I can't think of much more of a torture test for an encoder than constantly moving objects in constantly moving water. Every single pixel is moving every single moment in time. The picture is simply unbelievable.

Well, unfortunately my Sandisk Extreme III SDHC 8GB Class 6 (purchased Fall 2008) gets an error on LPowell's FHD, SH, and H settings.

Strangely his MJPEG settings work fine. Any guesses why?
 
lpowell,

Sorry if this has been asked before -- I searched but couldn't find anything.

With your AVCHD High Reliability Patch, is there any problem with checking the Native 24p mode?

Or is there a reason why you purposely left this unchecked?

Thanks.
 
Nevermind.
I was only searching in this thread, but just saw your post in the "to 24 or not 24" thread:

The disturbing problem I found in testing Native 24p is that it sometimes produces corrupted recordings that appear to play back normally. These flaws are visible but not easy to spot without using a frame analyzer. What seems to happen is that the AVCHD codec runs out of bitrate before encoding all frames in a GOP. It is then forced to write one or more empty frames at the end of the GOP. This causes the video to appear to pause or briefly revert back to the previous key frame at unpredictable points in the timeline.

While this encoder malfunction is fairly rare, I saw it often enough to conclude that it made Native 24p too unstable to support in my 40Mbps AVCHD High Reliability Patch:

Anyway, thanks for sharing your patch.

This problem can be caused by using an obsolete version of PTool. If you haven't already done so, be certain you're using the latest version of PTool by downloading it from the following link:

Hey that really worked, thanks LPowell. Now I just need to get used to restricting my shutter speed to above 50fps in low-light to avoid a huge drop in bitrate (latest test showed avg 9mbits/s in MediaInfo). Really thanks tho.
 
Hi Pj, with the 24p checked, can you playback on your camera? Will you get errors? Also what SD card are you using? Class 6? Class 10? Brand?
 
I applied the High Reliability patch and have been running into "memory card not fast enough" errors with several different card brands on SH mode (720p at 41000000 bitrate).

All of these cards give write errors at that speed:

Sandisk Extreme - Class 10 (200x) - 8GB
PQI - Class 10 (150x) - 16GB
Greenhouse - Class 6 dual channel - 16GB (so far the best of the lot)
Silicon Power - Class 6 - 16GB

This was with the 20mm lens on a rather detailed city street scene in full sunlight. Lots of movement, but also some areas of bright open sky which I thought might balance things out for the data transfer.

I'm pretty disappointed that the Sandisk Extreme card is giving write speed errors. It was by far the most expensive and I had hoped it would be problem-free.

Guess I'm going to have to lower the bitrate.
 
Are you starting already in focus? Try this: Put your hand in fromt of the lens when you start shooting and then remove it after one second. I know it sounds strange, but the camera sometimes has problems with highly detailed scenes when it starts up than go away once it has started capturing. Lpowell has tried to help this by setting the preset bitrates low, but maybe they need to be even lower. This would be a good test.

lpowell settings fails if I move a bit too fast, with cheap ebay noname 32gb SDHC (though they say "class 6").
I lowered bitrate to 28000 and overall to 30000, no problem now.
