Subtitling Video[edit]

Article(s): en:The_Devil_Bat

Request
Hi, I've recently found a video called "The Devil Bat". I've recently gotten into adding subtitles to it, but the media player that opens the video isn't very precise, it doesn't measure the milliseconds, different from the SubScript text thing it offers to use to add subtitles. I've already asked this question on the help desk, and a user suggested I try the Graphic Lab/Video and sound workshop.Is there something like an extension that can show the milliseconds/ zoom in onto the video-playing bar?

Best file format for 3 minutes 4K video of building demolition[edit]

Request

A chimney that was 170 meters high has been recently demolished by explosives in en:Leipzig. I’ve lent a 4K camera and got quite nice video footage from the event including the warning siren, the explosion, the collapse and the dust cloud. I cut exactly 3 minutes from my raw footage. It will be a nice addition to Category:Chimney blastings or Category:Videos of demolitions because it has better quality than most videos there, I think.

According to Help:Converting video I must convert the original MP4 to VP9. I tried to do that with ffmpeg like described under #Linux and OS X command line. The 4K file in VP9 is HUGE although everything seems correct. I am not a video expert. Is VP9 so much worse than H264?? I’ve got these files (specs from mpv output):

  1. 3.2GB 4K.mov: h264 3840x2160 59.940fps, pcm_s16be 2ch 48000Hz
  2. 28GB 4K.webm: vp9 3840x2160 59.940fps, opus 2ch 48000Hz
  3. 2.9GB 720p.webm: vp9 1280x720 59.940fps, opus 2ch 48000Hz

Which format would Wikimedia Commons prefer to receive?

What could be wrong about my files? Can I create a VP9 file of reasonable size?

Are there any alternatives to uploading VP9 like AV1 or even the original MP4? The help page doesn’t even mention AV1 but in this thread it’s been discussed but I don’t know the current state.

That doesn't seem right. Can you add the exact commandline you used ? For easy upload, try using https://video2commons.toolforge.org, which does the conversion for you. —TheDJ (talk • contribs) 19:30, 30 November 2023 (UTC)[reply]

@Frupa AV1 does work now with Commons. So you can try to do it with AV1. But there are some Videos that simply "explode" in size when encoded. Yours may be one of them. You can try to stabilize it before transcoding to webm, or you can split it into parts of - say - 5 seconds and transcode each individually. You may experience that all but one part generates a reasonable file size. If you concat the parts you will probably end up with a video below the 4GiB size limit.

@C.Suthorn, thanks for your reply! I’ve already successfully uploaded the video as File:2023-09-10 Sprengung Schornstein Leipzig-Südvorstadt.webm. Frupa (talk) 09:33, 24 January 2024 (UTC)[reply]

2 binaural audio files[edit]

Request

I have recorded two binaural audio files. Unfortunately, the recorder only recorded the first second and then deleted it again. However, I have a backup and I have uploaded it. The two tracks for left and right are not next to each other but behind each other in the file. I also don't know which track is left and which is right and the beginnings are not synchronised. Can someone take care of the files and put them together properly so that they can be listened to binaurally?

Subtitling Help/Advice[edit]

  • A video explaining how Creative Commons licenses can be used in conjunction with commercial licensing arrangements

Article(s): en:Creative Commons license

Request
Hello, I'm new to the Wikimedia Commons. I stumbled upon this video and saw that the subtitles were incomplete. I've added roughly two minutes of subtitles but wanted to know if I was doing the best practice and if there was any other information I should take into account when subtitling videos.
I hope this is the right place to ask a question such as this, but if it's not, I'd be happy to receive the correct location for a question like this.
