H264 to ProRes problems

Here's my current situation: I have 100Gb of material on h264, shot using a Canon 5dM2 camera. I want it converted to ProRes so I can do post work. If I do this convertion using Compressor, from h264 directly to ProRes, I get heavily altered images. By heavily I mean a 3 to 5% change in luminance (dark images).
If, however, I convert a h264 clip to an Uncompressed 10-bit clip, then take the uncompressed clip and convert it to ProRes, I get a perfect copy.
This poses a bit of a problem, for converting 100Gb of 1920x1280 30fps video to Uncompressed takes a LOT of time and disk space, and I'm supposed to keep shooting with this camera.
Anyone here had to deal with this before?

This is a known issue, of sorts - users report it, but Apple hasn't acknowledged it - and, yes, something in the translation between ProRes and h.264 produces the gamma shift that you're seeing.
Any luck converting those files to Photo-JPEG instead? If you set the Quality slider to 80, or even 75, percent, you shouldn't see any quality drop from your h.264 masters and the file size should be more reasonable than Uncompressed. You can then use those Photo-JPEG files to produce the needed ProRes files.
Outside of that, I've got nothing.

Export to ProRes problem. Please help!

I am getting very strange results when exporting to ProRes from Shake (Just "snow" on all frames). Export to uncompressed, DV etc works fine. Is there something I can do to fix this? Exporting to ProRes from FCP works fine.

Which revision of Shake are you running? I do recall getting this problem at one point and solving it with a Bytes node - but now running 4.1, I no longer get this error...

H264 encoding settings - problems with FLV/F4V conversions and playback... HELP!!!

I do a lot of LIVE ENCODING and have been struggling with FMLE. I own the Adobe Creative Suite of applications and am pretty familiar with working with compatible/required formats, etc.
We have been primarily using VP6/mp3 for encoding. Most of our work is SD. We also always seem to have trouble when trying to encode the FLV file to another format, audio always seem to be out of sync, but sometimes it works...
Do you know why that would be regarding the FLV audio falling off sync when encoding to another format, such as MOV? Also, when we try to play back the FLV, the audio sounds garbled up and only plays well in Adobe Media Player.
I keep hearing H264 encoding will provide better video, but I just can't get that to work. Also, why is it that my entire CS4 suite of applications can't read or playback the F4V file- that's unacceptable from Adobe, just a big huge pain the butt... I've had to buy several cheapie applications to try and read F4V files and try to convert it, except that converting F4Vs seems to be a hit-or-miss.
What should I be using to playback and convert F4Vs? I also heard changing the extension to MP4 works, but I haven't seen that work, not even once. The cheap video conversion apps I have that read F4Vs are: FFMPEGX and Wondershare (Youtube). Sometimes they open F4V, but not most of the time...
I am using a super fast new Macbook Pro i7, 8GB ram (not the thunderbolt/usb3), CPU always runs smoothly and effectively.
Also, I always use the Canopus ADVC-110 as my transcoder. I do both video via Firewire IN or Composite IN, then Firewire OUT into the Mac encoder. FMLE sees it ok, but I wonder if this device might be my problem.
VP6 settings are as follows:
VP6 video / MP3 audio
300 to 500k video
30 fps
640x480 in/out
44100hz audio
56k audio
We want to start using H264 encoding settings, but in my experience trying it out, the output file is ALWAYS PROBLEMATIC. Also, when testing a live stream, the audio seems to fall off sync with the video.
I am looking for your recommendations on the H264 settings I should try. Most of my events are simple meetings with 1 to 5 speakers, mostly talking heads. We rarely encode high motion video, but I would also like to be able to adjust H264 settings for both talking heads and medium to high motion without (any) frame drops.
I have tried streaming to multiple/different Flash Media Servers, archived only to file, and H264 results seem always bad.
Any recommendations from professionals in the live streaming arena are much appreciated. I thank you for your time in advance.
Thank you!

Hello Hugo
Sorry to know that you are facing these kind of issues, let me try to reply and understand issues one by one.
>>We have been primarily using VP6/mp3 for encoding. Most of our work is SD. We also always seem to have trouble when trying to encode the FLV file to another format, audio always seem to be out of sync, but sometimes it works...
-- Which application you are using to convert FLV to other format?
-- Is these any Audio - Video sync issue when you play FLV file in Adobe Media Player? if NO, it means FLV file created properly.
>> Do you know why that would be regarding the FLV audio falling off sync when encoding to another format, such as MOV? Also, when we try to play back the FLV, the audio sounds garbled up and only plays well in Adobe Media Player.
-- Which application you are using to convert FLV to MOV? if FLV playabck fine and without a/v sync issue, it should convert MOV with a/v sync.
-- It depend on audio codec selection by Media player or correct audio codec not installed for media player. Install appropriate audio codec to play in other media player if you dont want to play in Adobe Media Player.
>> I keep hearing H264 encoding will provide better video, but I just can't get that to work.

-- Adobe Flash Media Server version 3.5 and later and Adobe Flash Media Live Encoder 3 can record content in MPEG-4 (F4V) format using an industry-standard recording technology known as "fragments" or "moof atoms." Some MPEG-4 compatible tools and players do not support moof atoms.
The F4V Post Processor tool aggregates the information from all the moof atoms into a single moov atom and outputs a new file." You can download the tool from above location: http://www.adobe.com/products/flashmediaserver/tool_downloads/

H264 progressive / buffering problem - Media Encoder CS3

I am exporting using adobe media encoder CS3 with the following settings:-
Format: h264
Video codec: MainConcept H.264 Video
Frame height/width 640 x 360
Frame rate 25fb
Fields order - None (Progressive)
Pixel aspect ratio: Square pixels
Profile:High
Level:4.1
Audio:ACC, 128 (Kbps), 48Khz, Stereo
Bitrate settings:VBR, 2 Pass, Target 2.00, Max 4.00 (Mbps)
Stream compatability:psp
The files are being played on the web via the Akamai player via HTTP progressive download.
When the file is initally loaded it buffers the WHOLE file instead starting automatically - obviously this is is not acceptable when playing long files - having to wait for the whole file to buffer before it starts playing. I have used free MediaCoder to produce H264 and not had this problem - but to do this i have to export and intermediate avi file from premier and then encode again - however i am not so pleased with the encoding quality and would prefer not to have this extra step in the process.
I have found this fix someone has made to correct the files once exported from Adobe Media Encoder CS3 - 'QTIndexSwapper2' - this works well - files play and start with continuous buffering - but again its an extra step (i have a lot of file to export - just want to export with Adobe media encoder direct to web using the built in FTP function)
Please could someone advise on the correct setting for exporting from Adobe Media Encoder CS3 - so that file start immediatly on loading instaed of buffering the whole file.
Many thanks indvance

Hi,
Thanks for posting that link...some interesting points and comments at the end...re: quicktime "save as" and streamclip ( free ).
I don't do what you're doing ... though I've noticed if I put samples of video for web on my website for people to check out they always DL fully before playing...so I usually tell people to just save to disk first and then play the video...
Anything I uploaded to YouTube gets converted by them and plays right away and beyond that I've had no need to get into this subject.
Good Luck and if you find out more useful info let me know...others could benefit later from your solutions.

ProRes problems in CS4

I'm working on a project shot on the Red in 4K, transcoded to Apple ProRes 422 (HQ) 1920 x 1080 using Red Rushes. Now given the choice, I'd prefer to cut in Premiere on my PC instead of FCP on a mac, and on paper it looks like I should be able to; but I'm hitting a big stumbling block.
On the mac used for the transcode, the ProRes files play choppily in Quicktime but play smoothly in FCP. When I bring the files over to my PC, I get the opposite: the files play silky smooth in Quicktime, but when I bring them into Premiere they play back too jerkily to work with. It may just be that my PC isn't fast enough - it's a laptop, Intel Core 2 Duo 2.5GHz, 4GB RAM running Vista 32, fast enough to cut DVCPro smoothly but no match for a good desktop - but the fact that it can handle the footage in Quicktime makes me think something else might be the problem.
Is there anything obvious I'm missing? There isn't, for example, a ProRes codec project setting in Premiere - I don't know if that would make a difference.
Any suggestions gratefully received. I have other options (for one thing, I could just transcode to DVCPro HD instead), but I feel like there must be a way to make this work.
Thanks!

Jim: yeah, that was my original plan. But I'm getting very choppy playback when I import the R3D files, even with the resolution turned down. Which is frustrating, because (again) they seem to play much more smoothly in Redcine than in Premiere...
Shooternz: Apple relased the ProRes codec for playback on PCs earlier this year, which is why I can play the clips in the first place - like I said, they're absolutely fine in Quicktime, but jumpy in Premiere.
As I mentioned, transcoding to DVCPro is an option, and it's not that I'm stuck and unable to edit my project. I'd just like to see if there's a way I can do this with ProRes, which is a pretty great codec, especially if I want to work cross-platform: on paper, this absolutely should work, and I'm just trying to find out if there's something I'm missing before I give up and go for another option.

FCPX won't optimize to Prores 422 but to H264

Hello,
I am trying to do all the workflow of my gopro footage only with FCP X for convenience purpose.
The gopro outputs mp4 files
FCP can handle them very well (i had read the oposite on the web)
But i thought that prores was the way to go especially if I had to work with lots of clips.
So I decided to optimize files upon importing so that FCP X would transcode MP4 files to Prores 422.
But the outputs is H264, not prores.
It works very well (just like MP4) but I still would like 422.
I tried with Mpeg streamclip and prores was not available until I downloaded the codecs.
I thought dhis download would solve the problem in FCP but it didn't.
I tried with a clip from my iphone and still the same problem occurs.
Of course I could transcode with Mpeg streamclip like I did with FCP 7 but I would like to avoid that.
I am running mountain lion and FCP x 10,0,9 which is the latest version, I believe.
Thanks for the help !

Optimized media *is* ProRes.
If you control-click on a clip in the browser and choose reveal in Finder, it will *always* show the original media, not the optimized media. That seems to be what is misleading you. But don't worry, FCP X does optimize to ProRes, and it does use the optimized media when it is present.
If you are in doubt whether a given clip has otimized media for it, just control-click and choose "Transcode Media". If optimized media is already there, the option will be greyed out.

Best workflow to combine ProRes with .h264

Before I get any lectures - I know this is far from ideal.
But I have a client who only has .h264 files available along with some HD DV tape I can encode as ProRes.
Getting the original tapes or cards is not an option.
I know, I know - I've done enough tutting and head shaking for us all.
Meanwhile, I have converted the .h264 to ProRes and made them separate movies so they are now editable.
Does anyone have any advice on making the .H264 look as good as possible?
Final output will be for conference presentation so will be on a big screen.
The footage is well shot and was originally edited as ProRes. I just have misfortune to only have the .h264 versions of it.
Thanks for any advice.
I'm to give the client another good spanking (well, after the check has cleared).
Thanks again.

Garbage in = Garbage out. Meaning the footage can only look as good as the source. if the source H.264s are highly compressed, have smaller frame sizes and therefore you are blowing them up to full HD (or SD)...then there's only so much you can do. Compressor ProRes presets, MPEG STREAMCLIP...that's what I use. And ProRes has set data rates and sizes, so using Compressor and the presets might be the best you can do. If they turn out looking crappy...that's the fault of the source material.
You can only do so much.
After Effects or Premiere Pro might be the best options for outputting and cleaning up the mess. But if you have PPro, then I'd suggest editing in that, rather than FCP.

PP CS5 - handling and output of h264 (DSLR) files?

Hi all, new to PP (Mac OS 10.6.8, MacPro 1,1, 10 gig ram, RAID5 eSATA). Starting to work with my copy of CS5, beginning the evaluation process to migrate from FCP7.
I have a couple of questions about using DSLR native h264 files directly in the timeline.
I've got a sequence, about 1 hour in length, of all the camera original files strung together. While I'm reviewing, watching, etc., I notice a little progress bar in the lower right corner that keeps telling me PP is "conforming MVI_xxxx". What is it doing? As a bit of explanation, you may or may not know that h264s are verboten in FCP7, and I generally transcode them to ProRes for edit. One of my attractions for switching to PP is that I'm attracted to using h264 natively, but wonder if it's truly an efficient way to edit?
Secondly...I have the finished stringout sequence, and now I want to output it to a file so my client can review the raw footage. My initial test last night sucked...it took a bit over 8 hours to export a rather large (2.4 gig, 872x540 - though I'd set MediaEncoder to export a 960x540 field) h264 movie...which seems like maybe it was re-encoding my h264 files?
In the FCP world, I would have:
a) transcoded the h264 to ProRes (or whatever I was editing in) previous to edit;
b) created my stringout sequence;
c) exported a reference movie (quick, easy);
d) encoded using Squeeze, Flip-4-Mac or Compressor
So how do I do these steps, or something approximating them, in PP CS5?

Yes that is fine. Premiere needs to conform certain files in order to give proper playback.
Best not to start editing before conforming is done.
One on the reasons I can think of its taking so long is you changed the resolution on export, it has to scale the footage (assuming the original is HD)
And CS5 is a relative old version of Premiere it only supports Nvidia videocard to enable CUDA even with the hack,.

Problem working with avchd/.mts videos

I have to edit a video from several .mts clips. I don't know what camera was used for the shots. My problem is whenever I try to play them in either windows media player or gom player or bs player or splash (designed for HD videos), or edit them in After Effects, I get this strange screen tearing. I have tried to convert it into .mp4 (h264), but the problem persists. I uploaded it to youtube to test it out ( https://www.youtube.com/watch?v=bTfCP-o9RiY ), but the screen tearing occurs here also as you can see.
Does this mean that the footage is corrupt from the beginning and there is no way to fix it? The strange thing is that the guy who gave me these said he had these tearings also, but when another guy edited another video from these clips, it played without tearing, so it's not the camera's fault, it can be fixed. But if so, then how?

It is an unmodified clip without any conversion, it's what I got from my friend. It's avchd in an .mts container I believe. So the tearing is the fault of the recording and it is unrepairable? I will try to contact that guy, the problem is that I don't know him personally. Maybe he used clips which aren't tearing, and only some of the clips are corrupt like the one I uploaded, can that be the case?
Also, if needed, here is an unmodified, native copy of one of the problematic clips: 00134.MTS - Google Drive

Uncompressed Import Problem

I am trying to import quicktimes with "None" or "Uncompressed " set as the Codec.
I get:
"File Unknown: 1 file(s) recognized, 0 access denied, 1 unknown."
I'm using FCP 5.1.2 on my Powerbook running 10.4.7.
My final output is web and DVD.
Any Ideas?
Frez

Hi David,
The codecs I've tried for the quicktimes are "None" and "Uncompressed 8-bit".
They were exported out of QT 7 Pro.
They are 720x404 and were converted from VOB files (I am cutting together my demo reel).
I tried converting them using the Photo JPEG codec and they import fine. I also tried H264 with no problems.
My sequence is set to NTSC CCIR 601.
My sequence's compressor setting is set to Uncompressed 8-bit.
Mac OS X (10.4.7)

Proress to H264 colorshift

Color shift
HQ Proress 422 made before the new gammasettings, have great change in color(much warmer) when converting both from fcp, and when using compressor... Is there a way to fix this, not to try to adjust by eye with the simple color balance effekts in compressor?

x264 is an implementation of h264. The problem is, that quicktime does not support all h264 features. Sadly quicktime doens't support the comlete main profile:
From "REAL Ultimate Guide to x264 and QuickTime":
Before we get started, you should know that QuickTime is fussy when it comes to x264 playback. First of all QT doesn't support anything above Main Profile, meaning that it's built in decoder WILL support multipass, max 2 B-Frames, B-References, Adaptive Quant, multiple slices, CABAC, etc. Essentially everything in the Main Profile settings with some exceptions.
QuickTime WILL NOT support 8x8 dct and intra prediction, b-pyramids, lossless encoding, etc. As well as anything from the High Profile.
So if you want to play a h264 file (only mov or mp4 container), you have to make sure that it uses Main Profile and not the featurs QT does not support. And you must look at the bitrate limit and the limitations of the audio track.
you should use Apple TV or at least Quicktime presets of encoding software like Handbrake, StaxRip or MeGui.
If you have a h.264 file which uses h.264 features QT does not support, or a bitrate Apple TV does not support, you have to reincode. If you used x264 or another implmentation for encding is not important.

Adobe Media Encoder CS6 Random Crashing Mid-Render

Hello -
I've been dealing with this issue for enough months and across enough computers to finally seek out some advise here, hope it works out...
Basically I've got a 2 hour long film that I've been trying to export using Adobe Media Encoder CS6. It's never made it all the way through. I can usually skim through the generated quicktime file up to the point where the crash occurred. I've tried using that as a reference to check out my sequence in Premiere but there is never anything suspicious going on there. Most frustratingly the crash occurs randomly. Sometimes it will go through 10 minutes of the film; sometimes an hour. Regardless I get a crash with a report that has no specific information.
Footage:
r3d - Various resolutions, all being cut in a 2048x1152 sequence.
Quicktime mov - ProRes4444 for the most part.
Machine(s):
I had been attempting to render this for the past few months with a Macbook Pro running OSX 10.8.4 w/ 16GB RAM, 2.7 GHz Intel i7, NVIDIA GeForce GT 650M 1024MB - never made it through a render longer than 50 minutes of the 2 hours.
We recently got one of the new 2013 Mac Pro systems running OSX 10.9 w/ 16GB RAM, 3.5 GHz 6-Core Intel Xeon E5, AMD FirePro D500 3072 MB
The hope was that this new powerful machine would overcome the issues we were running into with these renders. Since I'm posting this now you can probably figure out that it didn't really work out that way...
Software:
AME- 6.0.2.81
Premiere - 6.0
I know there are updates to be used here, but whenever I update Premiere from just 6.0, the project itself becomes a buggy mess, crashing constantly. I also run Creative Cloud and have tried to just jump over to Premiere CC hoping all my problems would vanish, but instead, I again get a buggy project that constantly crashes. The only version of Premiere that seems to work with this project is 6.0, so general updates have not been useful (and instead damaging, I've wasted several days trying everything I possibly can to make the project work in the updates).
Any help appreciated. Thanks.

Thanks for the reply MMeguro.
Last night I was able to get my first full render through by doing a combination of things (so I'm not sure what did the trick in the end).
To answer some questions first, never attempted to do the FULL render directly out of Premiere, always switched over to AME for that, so that potentially could work too. Smaller renders have worked directly out of Premiere Pro, but they've also worked out of AME.
The initial render attempts that had been failing for the last few months were on the MBP which did not support GPU accleration due to an incompatible graphics card. I assumed the issue must be tied to something else because of this and was using it on the renders with the new 2013 Mac Pro. Using the workflow of Pr6.0, AME 6.0 and GPU rendering turned ON, I was failing to render to both Quicktime h264 and ProRes 422.
What worked for last night's render:
1. Convert Pr6.0 project to PrCC project (when I've done actual editing in CC after converting this project it tends to crash, but I figured just generating the project itself without doing any editing in it might satisfy what I was attempting to do).
2. Open AME CC and import PrCC Sequence. Used custom ProRes 422 setting.
3. Turned OFF GPU acceleration.
So as long as I the PrCC project I create stays stable long enough to save it (without crashing, which has been a problem with that Pr6.0 to PrCC conversion) then it seems like this will work. Kind of an annoying couple extra steps but I'm just out of my mind glad that I can actually render this thing finally. We're still in the rough stages so being able to turn around a review version within a day is very important.
Wish I could do more tests to figure out exactly which combination actually made this work for the benefit of others, but can't afford to do multiple 10 hour+ renders with random crash times.
Anyway, thanks again for the reply MMeguro much appreciated.

Drop frames on external monitor

Hi, recently im having some troubles with cc 7.2.1, one of them is when i have cuda enabled i have droped frames on my external and program monitor, but the timeline is fast and i can edit, im editing a short documentary with 4 hours of footage in h264 from 5D an 7 D, on a usb 3 external. I have a macbook pro (late 2013) 16G ram , i 7, mavericks osx.
When i select software only i dont have drop frames on my external but i can't edit, because everything on the timeline lags. Image takes a long time to load on the program monitor and external monitor, impossible to do trim, takes ages for images with time code to apear.
When scrubing on the timeline, the CTI takes a lot of time to catch up. It seems like she is connected to a ruber band, it moves back before moving to my selected position!!
Do you guys think deleting cache and preferences will help? ( how can i delete them ?)
Thanks

Hi,
I was wondering if there had been any progress on this? I'm experiencing a similar problem myself with my MacBook Pro (Late 2013, i7, Nvidia 750M) in that I'm getting dropped frames when using an external monitor. My set up may be slightly different though but the results appear similar.
My timeline, program and source windows are all on the external monitor (Samsung SA850) connected via thunderbolt to mini display port. The playback monitor window is set to full screen on the MacBook pro and that is where the dropped frames occur. If I unselect using a playback monitor and just use the external Samsung as described, things appear fine.
I'm editing a mixture of H264 and ProRes clips on an hour long timeline with nested sequences.
Any advice on possible solutions or things to try in order to troubleshoot would be much appreciated.
Many Thanks.

Export Help

Hello -
For years now, I've been downloading my Canon AVCHD home movie footage to Final Cut Pro (first 7, now X) and then burning the resulting project to Bluray via Final Cut's "Share" command. The resulting blurays looked stunning. As of late, however, I have been moving from burning to bluray to burning to hard drive (for an XBMC home media server) and the resulting footage is always, for lack of a better term, muddy. Does anyone know the settings I should use to retain the crisp high-def look I see on the original footage and the blurays? I have tried exporting to 1080p devices, h264, and ProRes 422 (LT). I hasten to use Master File because the resulting files would be humungous. Ideally I'd want to keep the resulting projects around the same size as the blurays (around 25gb for 90 minutes) which doesn't seem unreasonable. Any help appreciated!!!

Here's what I have done in the past.
In iDVD, use the "Save as Disk Image" (under File menu)
Then drag that disk image to Disk Utility (in your Applications folder under the "Utilities" folder)
Select that disk image, then click Burn up in the top left of the window. It will prompt you for a disk, insert disk, then it will prompt you for your burn speed. Select the slowest burn speed.
You should be in business.
Other things to keep in mind are labels can be murder. I know that but I still use them - I just can't send a presentation out without one - so I use the ultra thin labels you can get from Target - they are High Gloss DVD/CD labels from Neato. They seem to have fewer problems. Also make sure you buy good -R's. Maxell gets the highest rating, there are even websites dedicated to helping people track down the best current manufacturer, as sometimes labels (like Sony, Maxel, Fuji etc..) will change manufacturers and lose their quality.

Slight glitches in Source/Canvas monitor with CUDA MPE only

i7 3930k, Win 7 64-bit, EVGA GTX 570HD (2.5GB version). Everything is working correctly and stable (overall) . My one gripe is that when I toggle between CUDA MPE and software MPE, the software MPE is actually smoother in many cases. The CUDA is obviously working, but I get almost a slight shimmer running up the video (not tearing) , nothing terrible but certainly annoying. Its always about half way up the video where the shimmer starts and goes up to the top and disappears. Skipping through the video one frame at a time reveals nothing, its not in the source video, this has to do with decoding or aliasing.
It happens also at 100% pixel for pixel monitoring , I wanted to see if it was an aliasing issue, but the situation still occurs. Software MPE playback does not exhibit this glitch, so I've narrowed it down. The main question is are there NVIDIA settings in the control panel that may be not quite right? I've tried the defaults, and tweaked some of the settings, but there are a lot of options and I'm not sure which might effect the playback.
Seems to happen the most with H.264 canon files and some ProRes stuff I've imported, but then again turning off the CUDA MPE makes the problem go away....
Not a HDD or processor issue, those I've checked for certain.
I am running the new 6.0.2, but it happened before as well.
Already made sure the cores weren't parking, and they are all active....
Does anyone have any ideas?
Thanks for any help !

Hey I've been working on this with a few different systems as to try to figure out what is going on. First I am working on a Mac Mini 2011 i7 Quad with the crappy Intel 3000 low end 512MB graphics , and software MPE with the same H264 and ProRes files look flawless. Same with another PC Win7/64 HP Probook laptop I have, again with no GPU acceleration.
Last week I picked up Adobe PP6 classroom in a book and may have stumbled upon something. Maybe not.
Anyway on page 39, there is a paragraph on Maximum bit depth and Render quality settings, as specified in the sequence settings tab.
"If you enable Maximum Render Quality or if you have GPU acceleration, Adobe Premiere Pro uses a more advanced system for scaling images smaller. Without this option, you may see artifacts or noise in the picture when making images smaller. Without GPU acceleration, this option will impact performance."
Hmmmm... So I only see the "isssue" with the GPU enabled, and neither of those Maximum bit depth or Render quality options enabled on my projects. Yet without the GPU acceleration (MPE software only) and these options also not enabled, everything is fine (on my Mac Mini, my HP ProBook, and my PC where I am seeing the issue). This jives with my experience, so I am going to check those two options Monday when I get back to the office and see if that doesn't solve the issue. As if the preview monitors when GPU accelerated, almost default to a "draft" mode of rescaling/alising, this is perhaps what I am seeing. Blazing performance at the expense of a little image quality.
The computer is so understressed during H.264 playback, I'm seeing like 8% CPU total resource usage, that I can surely afford to crank up the quality and not see any kind of dropped frames. In fact when I view the 1080p @ half resolution, I still see the slight shimmer. And this is off an OCZ Vertex 4 via SATA 6g where I'm reading 450MB/sec without breaking a sweat.
