playback in premiere is choppy h264

[Angelo Lorenzo]

[Kyle Garvey] “Premiere seems to be having a hard time playing it back once color corrected”

So drop down your playback quality in your viewport to 1/2 or 1/4. Consider pre-rendering your clip/timeline

I tried that, and everything is rendered…still the only thing that plays is the audio and the first frame. The video doesn’t even play at all.
thanks,
Kyle

Go to Sequence > Delete render files and see if you can get any playback at all again.

Is this a constant or recent issue? Perhaps a restart is in order.

Which color correcting effect are you using?

How much RAM does your system have?

and importantly, where are you saving your media / render files and what are you rendering previews as ?
sounds like a slow harddrive to me

16gb of memory. and the footage is stored on a thunderbolt pegasus drive. I tried restarting the computer but that didn’t work. I tried trashing the renders, nor did that. The effects I have are Magic Bullet looks+mojo, and sharpening. However, even the clips that don’t have filters on them aren’t playing back
thanks,

looks requires rendering every time, and its very likely that because you’re playing from a clip with looks to one without (still h264)
your system is struggling to read ahead cache your media.

what format are you rendering your previews to ?
you can check by clicking sequence> sequence settings

Magic bullet looks can only use 2 cores in premiere as far as i’m aware. That would be the slowdown I believe

[Kyle Garvey]

I made a new sequence with just the raw footage and no filters, and it still doesn’t play. Any suggestions? I’m used to using FCP7 and just converting to prores prior to importing. Is it the fact that h264 is just not meant to be edited?
thanks,
Kyle

[Peter Berthet]

well you’re correct in some respects.
h264 isnt a great format for editing because its so heavily compressed and relies on the CPU to decode it in real time for playback.

Even on high end systems ive still seen caching issues cutting DSLR footage

again id suggest changing your render medium to something like uncompressed 8bit if you have the drive space

I can usually edit go pro H.264 footage without any problems. Its certainly not as smooth as a less intensive CPU codec, but besides the odd slow scrub here and there its almost perfectly seamless for me.

Thats editing on a macbook pro retina 2.6Ghz i7.
