Question

After adding two subtitle tracks, the 1080p export weighs in at 12GB. The source is was 999MB.

Perhaps after less than a week of using Premiere Pro, I can't expect to get optimal results, but my experience with this app is proving to be an ordeal.

 

Today, I finally managed to complete the export process, which last Friday seemed like an impossible task, partly because after opening a help request in the community https://community.adobe.com/t5/premiere-pro-discussions/all-export-attempts-have-failed/m-p/15513253#M571263

, Adobe support told me in chat that I would have to wait for the new release that would fix the problem, which was already known and cataloged as a bug.

 

However, the result leaves a bitter taste in my mouth because, even if I overlook the processing time of 4 hours, the file went from 999MB to 12GB.

 

The only processing performed was the addition of subtitles. Two tracks, EN and IT, but if I understand correctly, in embedded mode in the video, it only supports one track.

I am attaching screenshots of the timeline and export parameters


Where did I go wrong?

Hi Arturo266834390dbm,

 

The export size can depend on several factors, such as the codec used, Target Bitrate, and Bitrate Encoding (VBR/CBR). As Stan Jones suggests, you may try using VBR instead of CBR to improve storage efficiency. Also, in case you can't reduce Target Bitrate further, you may try using a more compressed codec like HEVC instead of H.264. This can further help reduce the file size. Hope it helps. Let us know if you have any questions.

 

Thanks,

Sumeet

@Arturo266834390dbm,

 

You're exporting HD 29.97 using a software encoding constant bit rate of 20 for a 1 hour 19 minute timeline. The subtitles add essentially nothing. It's all about the bitrate, length, and pixel resolution. Use a variable bit rate single pass. 

 

Your original sequence is variable frame rate, and I wonder if it was a more highly compressed format than H.264.

Hi,

Thanks for the message. I read that your export was unusually large. Can you create a screenshot of your export settings? I hope I can help you.

 

Thanks,

Kevin
