Slow Editing – AVCHD in CS 5.5
Hi Folks,
I’ve been looking everywhere and can’t seem to solve the problem I’m having. I’m editing AVCHD footage from at Panasonic HCX-900m camcorder using premiere pro and the scrubbing/playback is terrible.
Computer specs (desktop)
16gb RAM
i7-3770
256gb ssd scratch disk, 1 terabyte 7200 RPM storage drive
AMD gpuI thought it might be a problem regarding lack of CUDA support on my GPU so I tried editing on my laptop (also an i7, but no SSD, has Geforce 660M GPU) I enabled the card and have confirmed that the mercury playback engine is hardware accelerated.
When I try to scrub, or even just playback footage in the editing window it goes ok for about 3 seconds then just gets choppy and basically unusable. Is this just a result of working with AVCHD? I thought my setup would easily have enough oomph to handle this footage without much difficulty, but I’m at the end of my rope. I’m considering converting everything to cineform before editing because it’s so difficult to work with. Any advice would be appreciated as I feel like I’m missing something obvious.
Thanks in advance!
Take care,
James -

[James T'seleie] ” Is this just a result of working with AVCHD?”
Quite possibly. When we were on 5.5 we had to automatically transcode to Cineform just to achieve any level of smooth playback, and our machine was somewhat stronger than your’s.(4 disc media RAID, 24GB RAM and a Quadro 4000).
FWIW, CS6 improved on AVCHD compatibility, and in CC we’re currently having no playback issues at all, as long as no effects are applied.

Hi Steve,
Thanks for the info! I was wondering if it was just a setting or something that I had to tweak but it sounds like I’d be best off converting everything to cineform before editing. It’s an extra step but it’ll be worth it if I can functionally go through my footage while getting everything set up.
Thanks again!

I have a follow up question. I’ve downloaded the free “GoPro cineform studio” but can’t figure out how to transcode my files. I thought I would be able to do it within AME but I can’t seem to find the codec in there. I’m not sure where to look next!
Thanks for your help,
James
