MP4 conversions take 3-4 times longer than TS files

Mar 10, 2016 at 4:27 PM
First off, this product thus far has been great and I really appreciate the time and effort you all put into this. I wanted to raise a concern i am having with conversion tasks for MP4 files. I use Emby which now has the ability to transcode recordings on the fly to MP4 format. I like this because its smaller than TS and much more playback friendly. The problem I am having is that even though the format isn't changing - it literally takes 3-4 times longer to process the commercial removal. Previously, when I was converting from TS to MP4 and stripping out commercials, it would take roughly an hour.

I did setup a job to NOT convert the file format because clearly, i dont need to anymore and i hoped that would cut even more time off the task, clearly not. Has anyone else experienced this or have a suggestion that I can try to get comskip to run faster?

I can provide logs if needed. Thanks in advance

Thank you for your support!

You can start with the custom profile. Most likely it's because you're using the stock Comskip which comes with MCEBuddy, that' has a speed limitation (30 fps, so a 1 hour show will take 1 hour for comskip to process). If you update the Donator version of Comskip it removes the speed limitation and will mostly likely solve your issue.

Thanks rboy1 - i actually browsed the log file of the job after i submitted this ticket and noticed the following:
INFORMATION> --> Comskip version : FREE
WARNING> 2016-03-10T09:39:20 MCEBuddy.RemuxMediaCenter.RemuxMCERecording --> AllowH264CopyRemuxing is SLOW with the bundled Comskip. Use ShowAnalyzer or Comskip Donator version ( to speed up commercial detection. Codec detected -> h264

TS conversions didn't have that warning - so that would explain it. No free lunches I guess. Before I donate to them (although I am sure it's worth it) I want to see how well showanalyzer does. Thanks!
