View Full Version : How I bypassed QT slowliness in AE on Vista! ;P

Hi guys... found something interresting!

why?; cause sadly I got Vista on my new computer... was too time consuming going back to xp (cant make dban to work... weird!) and have jobs to do then I sticked to Vista... I am not regretting now... I fixed the few bugs by installing latest version of drivers and softwares and now its all well, booting in a fraction of the time my last xp comp did!

Only drawback now; Quicktime work like crap! was working like crap on xp too since version 7 but now its even worst even with the official vista update from apple.

In After Effects when selecting a qt in the projects windows, all AE freeze for 5-6 seconds the time to make the small preview... its not doing that with sequence or avi. I am now working on a projects with tons of huge digitals photos sequence and needed to do proxies. I did it in quicktime format first at third of resolution but it was even more slow than the originals huge sequence... Then I decided to try avi... I never worked with avi before... I really feel there is no professionnal codecs in that... I was right! no options theres... cinepack, microsoft videos, indeo whatever... all crap! heavy and too compressed! then I did a search on google for "Jpeg 2000 avi"... cause i love using motion jpeg B on quicktime when I dont need uncompressed... its the same codec Media 100 was using in the old days and they had better pictures quality than any Avid system! I know Jpeg 2000 is even better, giving you better quality for less size.

-----THE TEST:

I installed Morgan M-Jpeg2000 codecs, restarted After Effects, queued new proxies in that codec, render, set all my proxies with the AVI files.

No more waiting time. Instant preview in the project windows but more important; making previews in the timeline is way more fast... like 3 times more fast than using quictime. wow! Final render is less spectacular but here a test, I rendered the same sequence using both QT and AVI as proxies, render output was jpeg sequence for be fair;

using QT motion Jpeg B 80% - 55sec
using AVI M-Jpeg 2000 - 33sec

now saving the output in their respective codecs, QT proxy saved as QT and AVI proxy saved as AVI;

QT proxy output in QT format: 1min 29sec
AVI proxy output in AVI format: 36 sec

ouch! that was unexpected...


I will now use M-Jpeg2000 codecs for working, keeping the Quicktimes for final output only until Apple do something about it.


I think this is serious if like me you work with After Effects all day long... already the washed out colors was a problem with quicktime but having to wait after my previews like that was just too much for me... I will do the test on my xp laptop when I have some render to do.

Hope it help somebody...

mmm... sure you guys more wise than me and sticked with xp! ;)

thanks!

I would take those performance symptoms somewhat seriously as they are indicators that something is horribly wrong, and you won't be able to avoid Quicktime forever if you do a lot of After Effects work. I have heard that Quicktime and RAID systems under Vista do NOT play well together. Do you have a raid setup on your machine?

As for Jpeg2000, I know several visual effects studios that are using it during production so it must be fairly decent, however keep in mind that if you ever need to pass your projects off to someone else they may have a hell of a time trying to get your footage working!

Hello beenyweenies, I just changed some stuff in a AE scenes on my xp laptop... quicktime is pretty fast and normal! there is obviously something wrong on vista with the last qt update. Its simply not working.
...
ok, did the test on XP;

rendering qt jpegB 80% proxy to qt jpegB 80% output: 1min9sec
rendering Avi Jpeg2000 80% to Avi Jpeg2000 80% output: 38sec

mmm... think I will stick with AVI jpeg2000 for my proxies... this is a significant gap.

still thoses are home test on my own computers with klite codecs and other crap... it should not be regarded as professional benchmark! Another thing to take in account is on complex and long calculation that difference will be way less obvious. I was rendering 1 layers of a 2544x1696 jpeg sequence at half resolution.

lets back to work, I got tons of fluids to do for tomorow! - but always happy to lose some time on technical masturbation!

Hi Tfortier

Well that is a substantial improvement in speed! In terms of being a "scientific" test, I would say there is a bit of an apples to oranges comparison being made because you are using a different codec for each of those tests. If you're interested (and have the time) you might want to try using Jpeg2000 as the codec for both QT and AVI renders, and Mjpeg for both renders. That way you know if it is the codec influencing the speed or the wrapper (aka quicktime).

Either way I have been reading about people having Quicktime problems under Vista so I don't doubt your issue. Per my previous post, do you have a RAID setup in your computer? From what I've read this is a known cause of the Quicktime/Vista issue.

nop!, no raid setup... normal drive all the way!

You are totally right, I should have use the same codec! now I got tons of problem with realflow right now then Ill look at it tomorow...
have a wonderful day!
