And what does this quote prove?
Repeats what I said, nothing else. Many different cache file types to help/speed up Premiere re-open and work with source files (like conformed .cfa files for some compressed audio formats). CFA files are you gigabytes if you every worked with long files based on AAC or AC3. If you worked with PCM/AIFF etc based then you cache will never grown into gigabytes as .cfa are not created and there are no other big files except .cfa.
It doesn't say Premiere will automatically creates proxy files for compressed video formats- does it? This bit is just your wrong assumption!
Do you understand that I use Premiere daily on Mac and PC and I know about those cache folders and what is there.
You seams to have such a hard time to admit that you are wrong.
Premier doesn't automatically create any proxy video files (I don't think it actually ever did). You Adobe quote doesn't prove anything at all in this matter, so if you don't use Premiere and don't know how it works, please stop spreading this crap. All what you say is based on quote which doesn't say anything about video proxy files. You created this bit based on fact that in past you saw cache folder growing to big GB. You just refuse to understand that
it grows due to .cfa files which have nothing to do with video.
Well- exactly. All (or almost all) Premiere users will know that
Premiere doesn't create any proxy files for video part, so I agree with you that people don't need to be convinced. They know it or can check it. It's only you who needs to be convinced, but that seams to be impossible.
Drag h264 file to Premiere (let it create .cfa file for audio if it needs to) and you can start comparing playback of h264.
Do you think that this audio bit makes Premiere advantageous- just use MP4/MOV h264 without audio
It won't many any real difference at all- can guarantee you- but you won't believe me, so TRY yourself!
