Video_maker100 Posted February 27, 2022 Share Posted February 27, 2022 Hi everyone I'm using V11.20 paid licence. My source material is 4K approx 27000kbps @ 30fps using H265. When I export I always use mp4 H265 @4K. Have used this setting for a few years using the 32BIT version and always come very close to the source bitrate by selecting 30000kbps at the export screen. However, with this new version the bitrate is really low. I have created 2 videos and both come out at around 1400kbps and are noticeably poor quality. Does anyone have any ideas as to how I can get the crisp high quality I used to get with the 32BIT version? Thanks in advance Link to comment Share on other sites More sharing options...
borate Posted February 27, 2022 Share Posted February 27, 2022 Please share one of your videos and someone will check it out. Upload the file/s to a free server, such as Google Drive or MS OneDrive, get a shared (public) link, copy the link and paste it here or to me in a Private Message via the mail envelope in the top-right corner of this forum. When using Google Drive, if necessary change "restricted" to "anyone with link can view." Link to comment Share on other sites More sharing options...
Video_maker100 Posted February 27, 2022 Author Share Posted February 27, 2022 Will do. Outputted video again as H264 and got over 38000kbps. Borate - pm'd you the link. Thanks Link to comment Share on other sites More sharing options...
borate Posted February 27, 2022 Share Posted February 27, 2022 Thanks for sharing. Tests on the first minute of your project confirm that H265 exported bitrates are not what they were earlier. In 11.26 (64-bit), 30000 failed. High quality resulted in 6394Kb/s. In the 32-bit version 30000 succeeded, at 677Kb/s In versions 8.45 and 10.21 the result at 30000 was 14.1Mb/s This info has been forwarded to the developers.

Video_maker100 Posted February 28, 2022 Author Share Posted February 28, 2022 Thanks for looking - does this mean I need to keep updating until a fix is released? How long does this normally take? It's a pretty major issue not being able to output in H265 at a decent quality. Thanks Link to comment Share on other sites More sharing options...
borate Posted February 28, 2022 Share Posted February 28, 2022 Suggestions for now... *Use H264; it's faster than H265 and results look fine. *Try the MPEG4 encoder, which produces comparable results to H265 (IMO) and takes advantage of fast GPU encoding. Here are comparative results on the one-minute excerpt from your project... H265 @ 30000 102Mb file size; 14.1Mb/s bitrate (using version 10.21) MPEG4 @ average quality - 108Mb file size; 15Mb/s bitrate (using version 11.22) *Revert to this older version when H265 bitrates were high. No time frame for the fix, but the issue is being pursued, so stay tuned to this thread for future developments. Link to comment Share on other sites More sharing options...
HackerDaGreat57 Posted March 1, 2022 Share Posted March 1, 2022 Hint: you may want to port over some of Debut's source code 👀 - because Debut's MKV H265 encoder works without any issues whatsoever Of course the software is closed-source, so we can't do it ourselves... 🙄 Link to comment Share on other sites More sharing options...
borate Posted April 8, 2022 Share Posted April 8, 2022 It appears that this issue is resolved in version 11.43 beta. Give it a go, but bear in mind that it's a test release. Link to comment Share on other sites More sharing options...
Lancelot Chan Posted April 9, 2022 Share Posted April 9, 2022 (edited) I also encountered the same very low bit rate for H265 problem in 11.32 and 11.38, no matter what high bit rate I entered. I'll try out the 11.43 beta. ----- Tried, it works. Edited April 9, 2022 by Lancelot Chan Link to comment Share on other sites More sharing options...
borate Posted April 9, 2022 Share Posted April 9, 2022 Results of a 2:30, ten-track project exported H265 at 25000kbps with version 11.43. Link to comment Share on other sites More sharing options...
