Why don't VideoIntelligence end_time_offset values match for the same video ?
3 septembre 2022, par ProGirlXOXOWhen parsing the results of Google's Video Intelligence API, I've noticed that
speech_transcriptions
and all other annotation results are split into two separate list items withinannotation_results
. See the example output below.

Digging further, I've noticed they have slightly varied
end_time_offset
values.

- 

- Why are these
end_time_offset
values different ? I expect them both to show the exact same value since the exact same video is being analyzed for both sets of features. In some cases this value is off by more than a second. - Assuming this is not an error, which
end_time_offset
I trust if I want to determine the total duration of the video ? - Why is feature output split into two different list items ?

Best way to convert video from h264 to h265 and copy audio without lose too match quality
9 mai 2021, par user3449922I have some mkv file ripped from blu ray and I like to convert it to h265 with ffmpeg.


I have tried this command :


ffmpeg.exe -i title00.mkv -c:v hevc_nvenc test_2.mkv



and the result seem incredible : original size : 27 GB , output size : 1.6 GB


Francanly I don't expect a similar result that is very strange.


The quality seem similar at the fist look, but I don't belive it.


I ask if there is a better way to preserve the original quality and it is not important if the output size is 4 or 5 GB that is in all cases a excellet result.


I have Nvidia GTX 1060 6GB


Can you suggest me a best way to do it ?
