Jeff Mottle Posted January 30, 2014 Share Posted January 30, 2014 Hoping to tap the mind of some other Premiere CC users out there. In Premiere Pro CC I have a linked audio/video track and five tracks of audio all with track based volume keyframes. The linked Audio/Video track are all MOV files (ProRes) and all of the audio files are WAV files. When I try to render something out, it wants to "Render Required Audio Files" for EVERY SINGLE TRACK in the project, even if I am only rendering a 10 second clip. This process takes hours as the project has 8 hours of video and audio. I have 8 projects like this and all do the same thing. HOW ON EARTH are you supposed to get anything done if you to wait 2-3 hours every time I want to render a short clip!! I have never seen this issue in Premiere before so I have no idea why it's happening. It seems to have appeared in CC. Also having problems with audio from some tracks not rendering out for no apparent reason. Any suggestions? Link to comment Share on other sites More sharing options...
Ernest Burden III Posted January 30, 2014 Share Posted January 30, 2014 Poor-man's solution -- save a temporary version of the file, delete the timeline material not included in your clip? I have not had those sort of problems with CC but in fairness am not editing beyond a five minute piece. Link to comment Share on other sites More sharing options...
Jeff Mottle Posted January 30, 2014 Author Share Posted January 30, 2014 Hey Ernest, I've tried deleting any unused tracks. I even rendered out just the audio on it's own, created a new sequence and tried rendering the video and one 8 hour audio clip and it still wants to ""Render Required Audio Files" Link to comment Share on other sites More sharing options...
hockley91 Posted February 3, 2014 Share Posted February 3, 2014 Jeff, what about "reprocessing" the audio files in a different format? Just as a quick test? WAV to MP3? I had to go through all my files one time to find a corrupt "wav" file I was using. I ended up reprocessing it in a different format and then it worked fine. It was just trouble trying to find it. Maybe you render the sequence out with the audio tracks flipped on one at a time? You know, turn all the audio off and turn them on one at a time and see if it's working for you? I dunno. Perhaps there is an error embedded somewhere in the files that you are using and it's getting quirky because it doesn't know what to do? Link to comment Share on other sites More sharing options...
Jeff Mottle Posted February 3, 2014 Author Share Posted February 3, 2014 Yeah I wondered about that too so I rendered one of the WAV files to WMA and it make no difference. In fact I have one video track and one audio track, rather than the many tracks I have now to rule that out too. My next test is to move all of the files off the network and onto local storage. It's not a trivial task as each project is around 400GB in size x 8. With Adobe tech support they did a quick test and while it did not get rid of the ""Render Required Audio Files", it did render quicker. What does not make sense is that I've been running the media from a NAS for 6 years without issue, but with Premiere Pro CC is seems to be an issue now. I saw a few people on the Adobe forums reiterate the same thing. This whole "Render Required Audio Files" make no flippin' sense as it's never done that on any project I've worked on in the past, so I have to think it's new to CC.

Crazy Homeless Guy Posted February 4, 2014 Share Posted February 4, 2014 ......project complete and rendering out to compressed format? Two thoughts: 1) Can you pre-render audio? Sequence > Render Audio 2) Does it help to render to something like an uncompressed AVI, and then import those uncompressed sequences into Media Encoder for compressing.

Jeff Mottle Posted February 4, 2014 Author Share Posted February 4, 2014 1) Can you pre-render audio? Sequence > Render Audio That's what it wants to do by default and that's what takes 2-3 hours. I've not manually rendered the audio to see if it maintains that cache for future renders, but when it automatically forces the render, it wants to pre-render the audio EVERY single time you try to export a clip. So a 30 second clip takes 2-3 hours! 2) Does it help to render to something like an uncompressed AVI, and then import those uncompressed sequences into Media Encoder for compressing. I've not tried that yet, but might do it on a shorter clip to see if it helps. It will definitely take time to render out 60 hours of audio again, and a lot more space. The only space I have is 10TB of network storage, I don't have enough local storage for any single project as with uncompressed audio I'd estimate I'd add another several hundred GB on top of the 400 I need already. Going to give this a go though. Link to comment Share on other sites More sharing options...
hockley91 Posted February 4, 2014 Share Posted February 4, 2014 Well this is a doozy of a dilemma.... Link to comment Share on other sites More sharing options...
errollazare Posted May 9, 2014 Share Posted May 9, 2014 Hey Jeff, I signed up quickly to answer your question cuz I feel your pain! I found the solution to this! Basically you want to ensure that there are no audio tracks within your multi-cam sequence, just all your video angles. The audio is what causes the sequence to have to render. Where do you put the audio files? Basically when you nest your multi-cam sequence within another sequence you copy all the audio files to that same sequence as well. I hope this makes sense. Let me know if you are able to mediate the problem using this technique. Cheers, Errol Link to comment Share on other sites More sharing options...
hockley91 Posted May 9, 2014 Share Posted May 9, 2014 Jeff, I know this was a while ago, but were ever able to figure out what happened? It may help others in this area if you found a solution. Thanks! Adam Link to comment Share on other sites More sharing options...
Jeff Mottle Posted May 9, 2014 Author Share Posted May 9, 2014 There were MANY other problems that came up on this project and as a result I was put on the pre-release group with Adobe, but the cause for the issue described above was due to the audio bitrate for the project not matching the bit rate of the audio clips. It has a resample them as a result. Link to comment Share on other sites More sharing options...
