Creating a 10-hour video from a 60-second clip

[hojpub]

Greetings! I'm creating "relaxation" videos and I'm working with a 60-second clip that needs to be repeated to fill the 10-hour run-time.  Does anyone have any tips on using smart render to reduce render time?  What I've done is copied and pasted the clip end to end to fill a 10-hour timeline, and then dissolved between each instance of the clip.  However, even on my kick-ass iMac, it shows that rendering will take 60+ hours in Media Encoder. 

I thought that rendering the first clip to create a preview file would do the trick, thinking that when repeating the clip it would use the same preview file, and thus not require it to re-render when I choose "use preview file" when outputting in Media Encoder, but apparently, that's not the case.

Is there something I'm overlooking, or do I need to just accept a 60-hour render time for Pro Res HQ files?

Thanks everyone for any suggestions!

Hi Ken,

You should be able to render faster if the file is ProRes or the preview files are rendered to ProRes. It still does take some processing time, though. Do you have "Use Previews" checked in the Export Settings dialog box? More info please.

Thanks,
Kevin

Call me old-fashioned (been doing this since 1992) but I'm always a bit confused when I see posts about exporting out 10-hour video clips since most video programs are 1-2 hours, who actually watches for 10 hours straight? There has to be a better way, one would think. Like LOOP in the player? Especially since it's the same 60-seconds over and over, why create a 10-hour clip? How big is that? How will it be played/viewed? Maybe I'm missing the point - could be art 😉

So you don't want a jump every 60 seconds, so make a 1-hour clip and loop in player and have a jump once an hour. Or, I was just given an animated background (15 seconds) that I need to be looping for a LIVE broadcast event tomorrow. But not being created as a looping animation originally, the image jumps when repeating. I cut a few seconds from the beginning, pasted that material onto the end, and put the cross-dissolve there, and exported that edit. When loop playback goes from last frame of my new clip back to first frame, there is NO jump or interruption this way, as the frames being played at end then into beginning again are sequential as they were in original clip, if that makes sense.

Another tip, if you must export 10 hours - create say a 10-minute timeline sequence with your dissolves in it, then EXPORT as ProRes. Then bring that new ProRes clip into a new sequence and repeat it a bunch of times, then export again as the longer version. That may take better advantage of smart rendering. And I have no idea what format your source clip is, what effects might be applied, but in general I think with the nature of what you are doing it would've been easier from the start to do something like that rather than paste 600 instances of the same clip.

Thanks

Jeff, thanks for your response. Yah, I know it’s odd to create a 10-hour program. We create those 8-10 vids with ambient sound and video that people “watch” to help them sleep. They’re intended to played on TV while people sleep, or study, or just relax. So, the looping solution doesn’t work for this kind of programming. I sure wish it did. However, your suggestion of exporting a sequence as ProRes and then importing THAT piece into a new sequence and repeating seems like a great idea. I’ve been looking for something that would take advantage of Premiere’s smart rendering capability, and I think that just might do it. Thanks for your help and time! — Ken

Thanks, Kevin.  ProRes does seem to be the solution.  Yup, I have "use previews" selected.  So I'll give it a go with exporting to ProRes and see if that speeds up the process.  It's a crazy project, I know.

Thanks for your time and advice!

Hi Ken,

Have you found a better way yet? I need to also create a 6-hour long video for a Therapy sessions. After effects takes very long too....

Oh yes... After effects doesn't help much. Almost the same as Premier. I wonder how people can even render 2-3 hours. I need 2 hours to export 1-hour video. Please share if you have found the way. Thanks.
