Export time unusual?
Hello all – I’m working with AVCHD files in Premiere Pro 4. These m2ts files are coming from the Canon HF100. My machine has a 2.83 quad core, 8GB RAM and a 4850 series video card. All hard drives are 7200, non-raid.
I’m not sure if something has gone wrong, I’ve chosen a wrong setting, or if everything is working as normal. I’ve cut together my film, which clocks in at 1h45min. Less than 10% of the overall film has effects applied, including some from Magic Bullet Looks. I selected the AVCHD setting when starting the project, selecting the 1080i60 setting (as that’s what my camera saves to). I cut my film, and sent it to Media Encoder. I generally encode to an H.264 MP4, but this time I’m exporting the HD down to SD for DVD burning. I selected MPEG2-DVD, NTSC Widescreen High Quality, MRQ, Upper Field First, Quality set to 5, VBR 2 pass, min-3, Target-7, Max-8.
When I hit “Start Queue” it took about 4 hours to begin. From there, the queue has been running ever since. I’m now 24 hours in with a projected 5 hours remaining. Have I done something wrong or do the AVCHD files honestly cause this much trouble. Is a 30 hour render time normal?
A friend of mine using FCP suggested transcoding to something else before working with the files in PPro. Suggested Cineform. Another friend seems to suggest that I’m bottlenecking somewhere and causing a system slowdown. I’m clueless here and would love any help you might be able to offer. Of course, can’t really apply it to my current project, but it will certainly help me to make the decision as to whether or not to stay with PC, over the MAC.
Wow, hope that made sense.

There is a flyout menu on the right side of the encoder setting dialog where you can choose whether or not to keep XML data…it takes for freakin’ ever so i keep that unchecked. It should get rid of the 4 hours before getting out of the gate issue…
as far as transcode goes…Cineform is certainly an advantage for the computer…much easier to process. It would probably speed your transcode out as well. It sounds as if that’s most useful for next time though.
For this time, I’d just say that AVCHD is aggressively compressed and takes an immense amount of processing (more than HDV even) and changing codecs and doing the HD to SD scaling will likely take some time.
The only other thing I can suggest is an outboard transcoder like sorenson, or you could try QT Pro (a screaming deal to have anyway) and use a master AVCHD clip from PPro, but it would be a big file.

Yeah, that flyout menu is where you choose Max Render Quality (MRQ). I had already turned off the XML data, and didn’t really see an improvement in encode time. Does Adobe have the ability to transcode before you start editing, or do I need to find a third party program to do the transcoding?
