Files reconforming themselves in Premiere Pro CS6 – timeline not playing smoothly
Hi all,
My original source was digibeta – I captured over SDI as an SD Matrox uncompressed AVI file on a separate system using a Matrox Axio LE into Premiere CS5. I then moved this file over the network to my own system – a built from scratch Intel Core 2 Quad processor at 3.00 GHz with 8GB RAM and an NVIDIA Quadro FX3800 card. (As you can tell, I have limited knowledge on the guts of a computer). I am running 64-bit Windows 7 on this system and using Premiere Pro CS6. I imported the uncompressed Matrox AVI file into my project and for a while seemed to have no problem with it. I have not been using excessive plugins, but I have been using Dynamic Link to take some sections of video into AEX in order to use masks with feathering (wish that Premiere had this option). After a while, my timeline would no longer play smoothly. Sometimes I hit play and I see black in the preview monitor. Also, it seems that Premiere is reconforming my files for no reason. In the middle of editing, everything will freeze up and I’ll notice that the files are reconforming. It definitely seems that something is corrupted. So I went into the media cache and deleted everything in hopes that after reconforming (which is taking forever), maybe playback would become smooth and Dynamic Link wouldn’t be so slow. I was hoping that maybe something had become corrupt during one of the many times Premiere had reconformed a file. I’m still waiting on this, so I’m not sure if that is an adequate solution.
I have also experimented with turning off GPU acceleration in favor of “software only” – this does not seem to help.
I also notice that when I zoom in on the audio track, sometimes the waveforms disappear. If I adjust the track or wait a bit, they seem to reappear. Also, the “constant power” crossfade effect was causing Premiere to crash for a while – this project has been slow and painful, to say the least.
I am not unfamiliar with using SD Matrox uncompressed AVI files in my Premiere projects and have never had issues like I am having now. Can anyone offer any insight on what I can do to remedy these problems I’m having? Sorry for the lengthy explanation – Just trying to give all the important details that may play into what’s going on.
Thank you so much for any help,

How long is that captured file?
Have you let the system just sit and finish it’s conform?
I had an issues yesterday related to conforming, it’s best
not to do anything until it finishes doing that.What storage system are you using?
A RAID of some kind even a simple RAID zero helps performance
a lot with cs 6. -
The captured file is 01:29:23 and is 115 GB. I did allow it to conform – it took over an hour, surprisingly. It did not seem to make much of a difference.
I have two internal hard drives (to one of which the file is copied locally) each 2TB, and they are “mirrored” – though I’m not sure how the drives are raided/striped.
So even though I allowed the files to conform, I saved and closed Premiere, and upon reopening, Premiere is generating a peak file – this is specific to audio, correct? I’m just not sure why it didn’t save the peak file from before when I let it conform…

ya thats frustrated some when it happens (rebuilding the peak file)
it sounds like you already have the RAID.
What is the sequence setting codec?
I’ve found for example, using AVC Intra 100 to be much
faster in the editing phase, with the render codec set
for mpeg i frame.when done, I export it as ProRes or some other full frame
best quality codec. -
Hi Jessica,
Did you ever figure this out? Having a similar issue an in search for the answer.
Best,
Michael

Was this ever solved? We have the same issue – and it’s very random.
We set the scratch disks to follow the same drive letter/folder – but if we move from one system to the next (keeping media cache settings consistent) – prior to opening project – sometimes it re-conforms – sometimes it doesn’t.
Very random.
