Hello guys,

Could adobe give us the possibility to accept if we want .cfa or .pek file in cache ?

This audio file are too hudge it's ridiculus ? i never use them.

That remind me old avid system who encode each file you import ! unsuportable!

So Adobe any solution for the futur ?

Thanks for answers and sorry for my english.

    Well, actually you do use those files. They are the conforming of the audio to 32-bit floating point for editing. The PEK files are the Waveform Display files. They are large, but that's unfortunately the nature of editing video and audio.

    As far as asking Adobe to change things, you will want to file a Feature Request form. This is just a user-to-user forum, with no Adobe presence.

    Good luck,

    Hunt

    Thanks Hunt for your answer,

    i know what is cfa and pek files but cfa file are too much. pek file is accetable but isn't necessary to make a DVD.....

    For exemple during the creation of a DVD: i import an 60 seconds audio file (.mpa file of 2041Ko ) into Encore CS4.

    Encore create or conform for this mpa file a .cfa file of 28160 Ko in cache folder, more than 10 time it's original size.

    Pek file is reasonable for this 60 seconds audio file (111ko).

    Aberations are not finish, Encore repeate this conform operation in a random way (for exemple when i change aplication (if i clic on windows explorer and go back into encore program or if i re-open encore project etc...) so 28160ko X nTime the random way encore conform..... for only 60 secondes audio file....

    I'm working on dual layer DVD 8.7 GO project where there is more than 6 hours of audio & video. Do you better understand my pipeline problem ?

    So for  DLDVD 8.7GoX10 = 87GO in the best case, just to begin......for audio reasons ?

    It's why it could be reasonable than Adobe give us a way to stop this audio file conformation.

    Before, i made DVD authoring with Spruce DVD maestro and i never met this aberation.

    Even without this bug (conform several time the same file without understand why) i just found this way of working absurde because my objective is to make a DVD, and my audio .mpa file still the same .mpa file from the begining until the end of the process.

    Why an mp3 audio file must be conform in 32-bit floating point if you don't make any modifications on it ? i will better understand if i was working with soundbooth to make audio modifications .... Whatever...

    Sorry for my english.

    My conforming file problem (conform same audio file severals time in random way) comes from  Matrox AXIO LE Hardware inside my workstation (drivers must be buggy).

    In most case, i like validate my  DVD Authoring work with my client by exporting my DVD Encore project with flash incorporated export (at low size 480*270).

    It's more light than DVD's video_ts folder and so quicker to upload on FTP server. My client can validate easyly the DVD project online.

    This "flash" encoding methode stills too long compared to DVD encoding methode and you can't make any change without have to all re encoding!

    But, one more time, that creates additional hudge .CFA files in other media cache folder when exporting DVD project in flash mode (change Format DVD to Flash).NEW FOLDER "C:\NAME OF DVD PROJECT\Cache\Adobe Adobe Encore DVD Preview Files\mlf.cache.PRV"

    So, when you make DVD authoring and you validate your work with flash integrated exporter : you have the maximum CFA FILES, look the size of all .cfa files that create, it's completly crazy for only a small DVD project.....  No ?
