Interesting performance anomaly during video encode

I just noticed an interesting anomaly while my iDVD6 project was encoding video. I found that if I cover up the 'Creating Your DVD' progress bar and preview window with a Finder window, that video encoding seems to move a whole lot faster. I could tell by listening to the disk activity which seemed to be occurring about twice as fast. When I moved the Finder window away and exposed progress bar/preview window, then disk activity slowed down.
I opened Activity Monitor and looked at CPU% which showed about 70-80% with progress bar/preview window exposed. After covering up, the CPU% increased from 125-150% So apparently exposing progress bar/preview window slows things down quite a bit during video encode. I tried same trick during audio encode, and it made no difference. CPU% was about 7-8% during audio encode.
I was wondering if anyone in this discussion group noticed this performance anomaly previously.

Hi Paul
Yes I noted some relatively related phenomena during the rendering process
in FinalCutExpress that just selecting Finder seemed to speed things up.
Second: Please don't rely on the Activity monitor and most so when it says
iDVD doesn't answer. It's just rubisch. iDVD keeps on working - just wait and see.

MBP heating up during video encoding

Hi,
I was just working in Final cut express and my MBP became really hot. The temps are:
35C for HDD and 70C for CPU @ 3000 fan rpm. (using iStat).. [The idle fan rpm is 1999.]
I picked up my mbp and touched at the bottom of it (near the vent) to discover that it was really hot. Should I be concerned? Isn't it bad bad for the battery?
All help is appreciated.
Hassan

Video encoding is one of the most taxing things you can do on a notebook. To be honest, I would say that 70C and a fan speed of 3000RPM is actually very good for such a demanding task.
Just like a car, the harder you work it, the hotter it gets. If you think about a car idling... it sits there happy and fairly quiet... not push the gas pedal to the floor and the result will be quite different. That's basically what you're doing when you do something like encoding video.

Video Encoding Error after system upgrade

I recently upgraded to the new Maverick OS. I needed to burn some DVDs. Other than the other idvd projects needing to reconnect with the media they worked fine. but I have one that keeps aborting DVD burns with the error that it was aborted during video encoding. Has anyone else experience this glitch? Does it have anything to do with maverick? I have tried reconnecting the media, using different encoding formats, nothing has worked so far.

I too have the same issue. No problem before upgrading to Mavericks. This is what I found.
If I am using something I created in iMovie I have no problems. If I have a file not created from iMovie, I get the error sometimes. I create a lot of files from Handbrake to put on my Apple TV. If I select Apple TV 2 in Handbrake, I get the error when putting in iDVD. If I choose Normal encoding (default), I don't have the issue. Both are M4V files and are MP4 format. I look at the difference in the file encoding from command I in finder and there is very little difference. The one that won’t work has a codec called AC3. The one that works doesn’t have AC3 listed. In Quicktime, I do a command-I and I find the data rate is slower on the one that works. Other than that they are identical. Very strange. I am going to do what works.

Does video encoding settings affect menu quality?

Does selecting Best Performance or Professional video encoding have any affect on the quality of the menu video encoding or does it apply only to the added movies?

no one..

Error during rendering/encoding -- PLEASE HELP!!

Hey everybody!! After trying twice to burn this project to DVD, I'm about ready to rip my hair out!! First of all, here's the specifics about my computer:
Mac OS 10.3.7 / 800 MHZ Power PC G4 / 256 MB SDRam / My programs are iMovie 4 and I have iDVD5
OK, I'm trying to burn a movie that is about 1 hour, 23 minutes long. Even though my movie is not 90 minutes long, iDVD does tell me that it is too long and that I need to click on "Best Performance" in my iDVD Preferences. No problem, I did that. (By the way, at the time of the burning, I have about 5.1 GB on space left on my hard drive.)
Before burning I do repair permissions and delete my "com.apple.idvd.plist".
So, it burns and burns for roughly 6 hours. Right at the very end, the disk spits out and an error message comes up saying:
Encoding Video
Error during rendering/encoding:
This is very frustrating because I need to get this video done by tonight and turn it in by Monday morning!!
Any suggestions?? Please help!!! Thanxx!!

I have about 5.1 GB on space left on my hard drive
I don't think that's enough. Remember a DVD is 4.7GB (which iDVD first stores on your hard drive) plus temporary files that iDVD needs.

Error during movie encoding - tried all the common things, any suggestions?

HI, Attempting to burn a DVD from iDVD 7.11
I'm getting the "Encoding Error: There was an error during movie encoding" dialogue at the end of an attempted burn. Tried several times and many of the suggestions already on the forum
I have "shared" the movie from iMovie. When it first opens iDVD I have to change the default setting of "best Performance" to "Professional Quality" and the video mode to PAL (I'm in Australia). I change it both in the preferences pane (a change which seems to be ignored when I restart the program) and in the project info.
- I'm trying just to make a disc image, but haven't got past this first step to getting it to DVD...
- There is only the movie in my project (I've not added audio or pics in iDVD)
- I've used the "Modern" theme and deleted the default drop zones and menu audio,
- I've checked the chapter markers are not at the start of the movie or near any transitions,
- There are no special characters in the titles,
- All titles and menus are within the TV safe zone,
- I've deleted the com.apple.iMovie.plst files and emptied trash,
- I've tried deleting encoded assets,
- Repaired permissions, restarted the computer, checked for updated software,
- (tried a "safe boot" as someone suggested somewhere, but the program couldn't find the movie or audio files),
- I have 660GB free on the main hard drive,
- I've disconnected external drives,
- no error appear in map view,
- I preview the project and all appears fine,
The original footage was filmed for me. I was given a DVD which I ripped into an MP4, import into iMovie, edited the audio, added AIFF audio, added a jpeg image and 2 transitions. (Unfortunately the audio on the original I was given is unusable, else I could just copy the DVD I was given.)
So if anyone has further suggestions as to what might resolve this issue, please let me know!

Thanks for your post F, much appreciated
The project is 123 minutes, 4.16GB and it's being broadcast on TV, so I need max quality I can get (without spending money!)
I think I have sort of solved the problem - addressing what you've identified in a slightly different way.
Since my previous post, I noticed that clicking on the "Media" tab in the side pane, and selecting "Movies", my project was listed, but when I clicked on it, rather than the thumbnail I get on other movies I've processed, I got this text:
"This iMovie project can't be used because it hasn't been prepared for sharing yet. To prepare it for sharing, open it in iMovie and choose Share > Media Browser.... "
I did that (7 hours processing) then successfully created the disc image (2 hours processing). I have now burnt the DVD using disc utility (1 hour processing). It plays OK on the computer, but I'll need to check it on a normal player before marking this as thread solved (I don't have one here at home).
Unfortunately somewhere in all this processing the video has significantly lost quality. I thought I'd used all the highest quality setting, but will have to go back and check each step again. Unless someone reading this post has noticed anything I've done so far that would compromise video quality. The audio is fine - which for this project is the most important aspect.
So in regard to my initial problem; it seems there is a problem in iDVD not recognising/remembering the set preferences when using the "Share > iDVD " function in iMovie.
To summarise my solution for anyone else who experiences the same issue,
When sending a project from iMovie using "Share > iDVD " it seems you must also choose "Share > Media Browser.... "
This may be specific only to the case where PAL is required.
PS
I should also note, incase it made any difference, that I found the default headings in the chapter menus had dashes in them (i.e. it defaults to "Scenes 1 - 6", so I changed to "Scenes 1 to 6"). The only other modification I made since my original post was using stills instead of moving thumbnails for the chapter selection.

Is video encoding bad for my laptop A8-3500m processor?

I use freeware to convert videos from various formats to mp4 (Any Video Converter). Movies can take up to 1 and a half hours, but during the entire time my CPU usage hovers around 95% and the vents become quite warm. Should I stop video encoding? Or is it okay if I continue what I do now (no more than one movie a day)? I have the HP Pavilion dv6-6117dx laptop. AMD A8 3500m @1.5 GHz, 8 GB DDR3 SDRAM

If you keep your car in the garage it will last longer, too. As long as the system is cooled you will be OK. A computer CPU can safely run at 95% load for years on end. Booting it up and shutting it down causes more wear than running it at peak performance. After all, there are no moving parts in the processor. The internet is run on farms of servers that run at peak performance most of the time. It will move a lot of air through the system and may capture a lot of dust so you need to keep it clean by blowing it out with compressed air once every 6 months or so.

I repeatedly get "error during rendering/encoding of menus/slideshow" message. This process is the same on my iMac, MacBook and another iMac. I have been burning dvd's int he same way for the past 12 months using the exact same steps successfully.

I keep getting "error during rendering/encoding of menus/slideshows" message. I have been burning DVD's in exactly the same way for the past 12 months and mostly on my MacBook which is 3 years old. Obviously I'm using iDVD. I purchased an iMac about a year ago and moved to use this for dvd burning without problem. A few months ago (approximately) I started to experience problems with burning with the error message above. I tried everything including starting the whole process from scratch right down to capturing the movie clips from my video recorder into iMovie, then using them in iDVD. Still the same message came up. I lost count of how many times I repeated the process with different clips and variations and the same thing happened. This was also the case with my MacBook and my husband's iMac.
After taking both of mymac's tothe service centre, having new optical thingys put it and even a new hard drive on my iMac along with a new DVD burner the same thing happened. They told me it must be the process that I am using that is incorrect!
I took my 27" iMac to an apple shop and asked them to assist me while I use the same technique as I always had. The same message came up so they tried using my clips in one of their mac's. The same message. They tried it with different clips and the same message. The only way we could get theirs to work was with a magic DVD which did not produce what I needed and was limited with only one page.
I now cannot use any of my Mac's for the intended purpose that I bought them for - to produce good media for my work! It was suggested that I purchase some non Mac software to burn DVDs which defeats the object of having a mac with iDVD in my opinion. I have a book on iDVD which is very informative and have followed the process to the letter and checked all the trouble shooting and still no remedy. It was mentioned that an up-date may have caused the problem on all my macs.
I feel that this issue should be addressed by Apple as a matter of correctness.
I now find that on the net there are many posts in forums and such like with exactly the same (almost word for word) problems. Please Apple, keep/regain your good name and sort this out.
Jayne Connelly

Thanks Bengt W for your attention to this matter. So much appreciated. And thanks for putting me right on the aim of forums (new to this). Although, you may regret asking for more information. I've added everything I can below.
The process I used is as follows:
Import recorded clips of between 5 and 15minutes each from my video recorder into i
Edit the clips (remove unwanted start and endng)
Add title to front of clips
‘Share’ them to ‘movie’ (export using QuickTime)folder in .mov format individually
Open iDVD and ‘create new project’
Select ‘favourite’ theme that I have set up forall my work dvd’s (this has been used successfully many times and I’ve triedwithout using the favourite them).
Add 2 submenus for each group of clips
Select submenu - drag and drop between 3 – 6 clips in each of the twosubmenus
Change title colours on clips
Dragand drop image into drop zones where required
In‘map’ view I check for any yellow warnings before burning to disc
In an attempt to remedy the problems I’ve tried the following:
Try new DVD discs
Try different themes (favourites and standardones)
Change images in drop zones
Start whole process again even from importingfrom camera again
Two other completely different computers (iMacand MacBook) with iDVD
Go to apple shop and use their computers to doin iDVD
Try with one clip and no menu pages added
Use a clip that I already have that did notoriginate from my camera
Turn computer off and restart
New hard drive
New optical lense (thing)
New DVD burner
Saving to disc image rather than dvd disc
Other points:
I also have a ‘flip’ and ‘iPhone’ whereI’ve imported footage camera which, although limited, records and makes videoclips and burns them to DVD through iDVD without problem.
For example, I have just gone through steps 5 - 11 using some clips that were already imported from my iphone to iPhoto and dragged across. I used a theme that I've used before which has failed and added one sub menu page where the clip went. It burned to disc image successfully.
The startup disc, I believe will have no space issues asit’s a new hard drive with no use apart from this. That could have been an issue before (I didn’t check it) butnot now.
Other technical stuff that I don't understand but you may:

Error message during burning: Error during rendering/encoding

Hello,
I am using iDVD 6.0.2 to create a DVD. I have pictures and videos. The videos are in .ASF format and they are played on Quicktime on my computer.
Anyway, when I go to burn the DVD, it goes through the slideshow fine. But then, once it starts videos, it stops and the following error message shows up:
Encoding Video
Error during rendering/encoding
I am using a Memorex DVD-R (8x, 4.7 GB, 120 min video) dvd. Is there any way possible I can fix this problem? I really need this DVD soon. Thank you so much.

Best Buy and Office Depot carry Verbatim by me. Use only DVD-R, not DVD+R.
My guess is that .ASF file...........
Suggest you create a disc image and then burn the DVD. File/Save as Disc Image...
http://docs.info.apple.com/article.html?artnum=164927
This will isolate any encoding/burning issues you may encounter. Once the disc image is created, double-click the .img and burn the virtual disc that should appear on your desktop, using Toast to burn the DVD. Disk Utility to burn the .img file. Usually, you can select a burning speed in Disk Utility.
There are variations to this process based on which OS X you are using...
Open Disk Utility (in Utilities folder in Applications folder), click on the virtual disc (maybe the .img) in the left-hand window. Click the Burn icon. A new window should drop down and your SuperDrive tray will open after clicking the Burn icon. Insert a recordable DVD. (Verbatim DVD-R preferred by me.) Click the Close button. Wait. Select a burn speed. If you hold your mouse cursor over the pop-up it says: "Select a slower speed to work around burn failures," so select 4x or slower for best results. Then click the Burn button.
-->If the virtual disk selection won't allow you to click the Burn icon, use the .img file instead. This may have changed in 10.3.9 and did change in Tiger.
Also, you can use DVD Player to play the virtual disk to check your iDVD project before burning to DVD. Launch DVD Player. File/Open VIDEO_TS (Open DVD Media... in Player 4.6). Find the VIDEO_TS folder and open that. (The audio folder is for DVD-Audio disks.)

Freezing with iTunes 7.6.1, thumping sound,especially during video playback

Hi,
Has anyone noticed a decrease in system reliability after upgrading to iTunes 7.6.1, especially during video/videopodcast playback in iTunes on their MacBook Pro's?
Specifically, the entire system locks up. Reminds me of the days of OS 7.5.5 when the mouse cursor freezes, keyboard stops responding. The only way to proceed is by holding down the power button.
This has occurred about 4 times now. The trackpad will become unresponsive, keyboard buttons such as caplocks and nu lock will be unresponsive too. Most interesting is that the sound output will loop, usually a short bit of the last audio played back over iTunes.
Videos which have triggered this:
- Podcast: Diggnation
- Podcast: ABC World News Now
- YouTube video's converted by Tooble
Here's a video I recorded showing the thumping noise. It sounds like the last audio dump before the crash looped. It's not coming from the hard drive. Definitely from the speakers.
http://www.youtube.com/watch?v=wzOCcINoClg
In the video you see I had World of Warcraft up, but I don't think it is the problem, because this kind of crash has occurred while using other programs.
Details:
iTunes 7.6.1
QuickTime 7.4.1
Mac OS X 10.4.11
2.2 Ghz (MacBookPro3,1)
4GB RAM
External second monitor attached: eMachines 15" LCD
Prefrence panes additions: Application Enhancer, Divx, FinderPop, Flip4Mac WMV, Perian, Teleport, WindowShade X.
Have NOT installed Security Update 2008-001 OR AirPort Utility 5.3.1 pending user problem reports.
I never had such a complete system freeze until about the time I updated to iTunes 7.6.1. Repaired disk, permissions, cleaned up virtual memory, cache's using AppleJack.
Thanks, just want to see if this is an isolated problem.

First, create a new user account and see if you can replicate the problem on that account.
If so, start by killing all the running daemons that aren't OS X-native apps. In other words, Window Shade X, Application Enhancer, divx, etc. Quit all that junk and use Activity Monitor to make sure those apps aren't running background tasks. I'd be willing to bet that Application Enhancer is the culprit.
See if that solves the problem. If so, you can add the applications back one by one until you find the one that's causing problems.

Flash 8 Video Encoder, audio/video discrepancy from mpeg

Two questions...
First, more urgently, I've been given an origianl
720xsomething mpeg format video, and I'm trying to bring it over to
flash... I use the flash 8 video encoder, which does a phenomenal
job of keeping video quality while vastly reducing file size, but
in this case, (unlike some others in the past) I'm getting a
bizarre discrepancy between the speed of audio vs. speed of
video... I can't find a way to force the mpeg (or flash encoder
software) to TELL me what the frame rate of the original mpeg is,
and even when i attempt to force it to 24 or 25 during conversion
to flv, it doesn't seem to bother matching it up to the audio...
when i take the result and export it from flash, i'll try, at 24
the video is going too fast for audio, but at 23 its going too
slow...
and this SEEMs related to 2nd question.. I took about 15
solid minutes of video of a particularly nice sunset in
progression, with the hopes of compressing it down to about 30-60
seconds for effect... but it seemed like, no matter what frame rate
I tried to compress it to with the encoder, it just drew each frame
out to a set length, and even if i tried to export the flash really
fast, it remained at the epicly slow frame rate...
is there a relation? what am I doing wrong?
is there a way to detect the ACTUAL frame rate of the
original mpeg... is there a way to force the audio and video to
remained sync'd up? Seems the that problem is, if i go with the
default 'Same as source' I'm left to guess what that might be when
exporting from flash, as nothing ever actually tells me what that
source frame rate actually was! Is there some natural audio
compression business inside mpeg video that works fine for mpeg
video, but the flash encoder can't handle well? I've tried it with
about a billion different frame rate, audio data rate, quality, and
export settings, and have yet to get a sync.
Thanks in advance!

I should have been more clear.
I changed the file name from .vob to .mpg and then tried to
add the video file to Flash 8 Video Encoder and received the
following error message:
"You won't be able to encode this file. Your computer doesn't
have the necessary codec or the file is corrupt."
Currently,
I use ffmpegx to convert the .vob to .dv and then, I import
the .dv into Flash 8 Video Encoder and convert it to a .flv....
I can use ffmpegx to go straight to a .flv, but the file size
is larger b/c the compression is different, not On2 VP6...
I would like to skip the middle step because my files are
very large and it takes extra time.

Psychedelic screen artifacts during video

During video playback, the pod started "messing up" the image. At first, it was the centers of the letters on the beginning credits blacking out. Then, areas of solid black were being replaced by pink and purple -- well, this video was encoded as grayscale so there is no purple. This video had previously played fine on the Mac and an older video ipod. To see if maybe the video file itself had become corrupted, I tried a different movie (in color), one from iTunes store. Video on this one was totally psychedelic, and then the frame began shifting. "Horizontal Hold" was slipping, if you are old enough to know what that means. Lol.
A reset of the pod fixed it up. Anyone else have a problem like this? I just hope it doesn't keep recurring....

Make sure you're running Touch software 1.1.2.
You might want to restore it once with 1.1.2 to see if that helps.
I've not really seen this since the pre-1.1.2 days...

IDVD video encode error when burning to DVD

I am trying to burn a new copy of a project I successfully burned to DVD 2 years ago. I have not changed the source material. After the menu renders and video encoding begins I immediately get an error message "video encoding error." There are no menu warnings. All video is successfully previewed. Nothing has changed from the previous burn. The project info box shows all video and audio properly encoded and present.
What gives?

The way from FCE or FCP has been the same for me for lot's of years since FinalCut 1.2.5 I think (was no Express or Pro then)
And QuickTime Conversion never worked for me - I guess You were lucky two years ago.
FCE/P to iDVD
Several things
• How to go from FCE/P to iDVD
• Free space on Start-up hard disk
• Encoding
• Brand and type of DVDs used
• Burn speed set
• iDVD BUG
• Chapters
How to go from FCE/P to iDVD I do
• Disable Screen and Energy saver
• IMPORTANT --> FIRST in FinalCut - Mix Down Audio under Sequence Menu / Render Only / Mix-down
• Export out as a QuickTime .mov file
• Select with Mark - Chapter Mark
• Not as Self-Contained (not important but saves time and space)
• NO QUICKTIME CONVERSION (IMPORTANT)
This QT.mov file I import into iDVD from within iDVD.
Free space on Start-up hard disk
I set a minimum of 25GB (for Mac OS and iDVDs temp files)
Just double click on the Hard Disk icon (top right on DeskTop) and read on bottom part of this windows frame e.g,
( in English - 1 of 14 selected, 38.24 GB FREE)
Encoding
• I use Pro Quality encoding if material (video + menu) exceeds 40 minutes ! if less I use Best Performances
Brand and type of DVDs used
• I use Verbatim
• I use DVD-R
Burn speed set
• I set down this to x4 (or x1) - BEST IS NOT BEST at all only fastest and results in Maximum amount of BURN ERRORS !
iDVD BUG
• One can not go back to movie-project for any alterations and then go back to
the iDVD project. It will notice and ask You to either Up-date or Cancel. Neither
of them will work.
Medicine - Start a brand new iDVD project.
Use of Chapters
• I only use a to z and 0 to 9 in naming them. NO other symbol/letter !
• NO Chapter-mark at very beginning - iDVD NEEDS TO set this by it self
• No Chapter marks in or within two seconds from a transition
(Way around this last one - Export movie as QT full quality and NO Chapter marks
Import this into a new Movie-project and now You are free to set C-Ms where You want
them except at very beginning - still)
Material used to build movie
• video - I use streamingDV (or convert all other to this e.g. .mp4, .avi, .wmv etc)
• audio - I use .aiff 16-bit 48kHz or from Audio-CD (44.1kHz) - no .mp3 or direct from iTunes
• photos - I use .jpg - no .bmp etc
Trash iDVD pref. file and run Repair Permissions - and have a re-try.
from post ??
May not be relevant, but I had the same problem with iDVD, where burned DVDs showed a green screen. It was cured by quitting Quicksilver and Quickeys as well as disabling sleep and screen-saving

Help - no audio during video chat

During video chats with another mac user, we both have video and can see each other, but neither of us has any audio. When we do just an audio chat, we can both hear each other without a problem.
This happens on my MBP with 10.6 and iChat 5.0.1 and on my PBG4 with 10.5 and iChat 4.0.8. The other computer is an iMac with 10.4 and iChat 3.1.9.
Any suggestions?

Hi,
So this is Linksys Modem that can Route with a Airport in Bridge Mode ?
Good.
IS it using UPnP (in the Administration tab) ?
If it is then Port Forwarding, Port Triggering and DMZ should be Off in Gaming and Applications.
In Security tab (if it has one) the Firewall should be disabled (If it has a setting) as this interferes with iChat.
The Bit about "Responding to Anonymous Requests (pings) should also be set to Allow them (ichat Sends a Ping).
I have had a Netgear DG634G and currently a Sagem 2504 Fast Modem that both Report "Port Restricted". It is not a deal breaker.
More interesting is that you see no incoming Audio.
Get the Buddy to check his System Preferences > Sound > Input tab has the volume high enough and the device here and in iChat > Preferences > Video Section match in the Microphone drop down.
He/she should also check the Video Menu and that Microphone Enabled is ticked.
If those things are in place then try the Bandwidth in iChat at 500kbps
(Try it at both ends, then use the Connection Doctor > Statistics to change one end at a time to higher settings - wait for the Bit rate to settle).
The Bit rates you are seeing look OK (As does the other info)
The Bit rates at the Buddies end should have got a Message from iChat that the Connection is too low (Below 50kbps) for a Video chat.
Are you sure these are from the same Conversation ?
If the Buddy is on Leopard or Below they should go to System Preferences > Quicktime > Streaming and change the setting to 1.5Mbps to get iChat to "see" as much as is practical of the internet speed.
It is almost as if they and doing a Download at the same time (Or another computer is taking all the Bandwidth)
What Internet Upload and Download Speeds are they paying for ?
What are they actually getting ?
Click the yellow star And the Start Test box.
If you are connecting in Video chat with th VPN active I don't think this is an issue (unless it is using up lots of Bandwidth - you results suggest not).
The issue seems to be at the odd results your Buddy is getting.

Flash 8 Video Encoder multiple instances

Is there any way I can set up to run multiple instances of
Flash 8 Video Encoder to take advantage of a multi core resource? I
have a dual CPU dual Opteron box (ie, 4 cores available) and find
it disappointing to see such slow renders and all that CPU going to
waste.
On the other hand, does anyone know of a really good, fast,
multi-threaded ON2 VP6 solution? I also use Autodesk Cleaner which
is still dependent on the Flash 8 encoder (and therefor on
Quicktime) and doesn't do any better, and is also very unstable
around Quicktime.

Ah, yes, I had missed that, thank you. There are two sliders

both sliders maxed, with the same result. It may be that on a
machine that hasn't got much headroom, or is concurrently doing a
lot of other work, that this makes a difference. It may also be the
difference between the Win and Mac versions of the software and the
respective OSes. (Maybe it isn't even hooked up for
Win :-) )
Anyway, really appreciate the input, I'm pretty sold on
Squeeze with ON2 VP6 for my Flash work, sticking with Cleaner for
my Windows Media, runs really well. I've just started an overnight
test running Squeeze on Flash output and Cleaner on WMV output
concurrently. Still no where near maxing the cores, so will be
interesting to see what it does to render times.
