Long Compressing time in Compressor
by nyphotoga on Jan 16, 2008 at 6:05:15 pm

Hey everyone, cant get enough of the Cow....
but I have a question, I have researched it and cant seem to find too much on the subject.

Im compressing short clips, 10-12 mins edited video from FCP thru Compressor to H264, using web setting in Compressor. I think the quality is good, and am getting file sizes between 80-130mbs which is acceptable to us. The video is shot with HVX 200, and edited in FCP on a Mac DP 2.5gz with 8gig Ram and using Medea RAID drives.

Compressing video 10-15mins long is taking approx 1 1/2- 2 1/2 hrs... Ouch. Now some of the video is being used on web sites and Im looking for a faster way of getting this done. Are there any solutions that anyone is using that allows faster compressing times. I have tried it on a friends Mac quad core, and while it is less time, not significantly less...

I have heard of a little device, Elgato, and some people swear that it is faster, but are there any hardware solutions that can speed this up..

tks

George

Compressor is slow... but usually not that slow.

what are the specs of your CPU?

Hi and thanks for the interest in helping.

I did put the info in my post but here goes. Im using a Mac Dual Proc. 2.5 G5 tower, with 8gigs of ram and medea raid drive. Im exporting the file thru compressor using the Web Setting for Quicktime 7 which works and produces great files for me. In the frame size setting, Im using 320 x240.

the video is shot on a HVX 200, in 720P60 and edited on FCP 5.2. Once edited, Im exporting to compressor with the settings above. It is pretty slow... some of the specs I have read do complain about the 1 hr per 10min time rate for compressing... So Im sure it is not my machine, since everything works fine with no problem.

When exporting I do export the timeline from my raid drive, to the internal sata drive. All specs, and recomendations have indicated that exporting from 1 fast drive to another fast drive is better than working and exporting within the same drive.

Really my question is have anyone used elgato, hardware usb device used to speed up compresion.

Second question is are there any hardware compression device that will work on a mac which will speed up the process. We are trying to make the video shot available online faster than now. It presently takes us about 4hrs to get it out and to the web clients.

1hr. editing, 2hrs+ , compressing and then another 1hr to get it into the right flash or web format..

tks

George

Not having access to compressor at this time, could you remind us by detailing the 'Web setting'.
The things that slow encode times down are multi-pass encoding, and any other settings that are on 'Best' rather than 'better' or 'normal' like deinterlacing etc.

Using 320x240, AAC Stereo, 100 % frame rate, multi pass on, H264 at 800kbps.

These are the pertinent settings, I know using higher levels of compressing and shutting off multi pass, can decrease the time, but I have tried these and the quality suffers, especially with more motion in the video. I really do think, that there isnt much to fix other than, to either find some hardware solution, or seriously compromise quality.
But thanks for your interest and answer.

You could try some alternative routes using either:

MPEG Streamclip:
http://www.squared5.com/svideo/mpeg-streamclip-mac.html

or ffMPEGx
http://homepage.mac.com/major4/

or isquint:
http://www.isquint.org/

All of them should be (much) faster than Compressor.

or take a look at the Elgato Turbo H.264 hardware accelerator product.
