Crazy render times on MBP? at DVinfo.net

Joachim Hoge · July 30th, 2009, 01:37 PM

I wanted to have a quick look at some footage I shot with my EX-3 and a set of Canon lenses I got hold of.
I put together 1 minute of EX HD 1080 25p footage that I wanted to watch using my WD HDTV box hooked up to my 42" tv.
I need to render the footage to a format the player recognize, so I choose h.264 Quicktime.
I always use the Mac Pro in our editing suite for rendering, but this short ting I just wanted to do on my MBP 2,5ghz.
It´s been 30 minutes now, and Compressor tells me it´s 1h 10min to go!!
Is this possible?
I have turned frame controls on otherwise left everything as is.

To show a similar workflow I shoot 1920x1080i 25np at 100mbs avc intra on my panasonic 301, it goes into FCP as pro res 422 at the same rates and I can output to pro res 422 at 1920x1080i 25np in virtually real time, I can also output to apple tv h264 at near real time which I then watch on my WD tv box via a memory stick.
I dont use compressor and just go straight QT out of FCP.

Hope this helps pro res seems to be a key here as it is very efficient for output to master and apple tv, I have a 2.16mhz MBP.

Thanks for the reply Gary.
I´ll look into that workflow. I didn´t think of going to PRORES because of space issues on my MBP and I don´t have an external HD here now.
Do you use the log and transfer to go to PRORES?

PS 1h30min left now, oh dear

Update.
First of all, the clip was 8 minutes, not 1 as stated above
I cancelled the job and started over writing it to an external HD instead. The job was done in 40min. This was a portable USB drive as I wanted to play the clip on my WD HDTV. Would probabaly been faster if I used my FW800.

Yes I use log and transfer to go pro res, you really need an ext firewire 800 7200 drive as well but I have done small quick turnaround jobs using the internal esata drive.

I have also gone straight export to USB memory stick to speed up the delivery of an apple tv file to the WD box.

Ok.
I posted this in another thread just now, but here it goes again.
I tried to play back the clip on the WD (8min, 3,5GB H.264, 1920 25p), but the WD choked on the clip. I think it was due to the file size.
A 30 sec version played back just fine

That's an enormous H.264 file for just 8 minutes. What bit rate is the file? For web streaming I am creating 8Mbps H.264 1920/30p files that run to about 50-70MB per minute & they play OK on my WD TV.

I wanted to look closely at the footage I shot so I just converted it to self contained movie to keep as much of the original quality as possible
