Subtitle timing is substantially off

HelpdeskCategory: QuestionsSubtitle timing is substantially off
Ethan asked 10 months ago

Hi, I’ve just tested out Clipscribe for the first time. I uploaded a 3 minute video, with good quality audio from a lapel mic.
The good: the designer is great. The software has a lot of promise.
The bad: I was really disappointed with the subtitle timing.
There were lots of mistakes in the subtitles themselves, but I can live with that.
The big issue is that the subtitle timing had so many issues and mismatches with the audio. Subtitles disappearing while I was still speaking. Or the next sentence showing before I started. Blank parts that didn’t match my pauses etc.
And it was extremely painful to try and fix this by tapping on the little up/down timing arrows dozens of times for each sentence, to try to get the time to match.
It took me almost 20 minutes to fix the subtitles for a 3 minute video. And that obviously is not the purpose of the software.
I don’t know if I’m missing something, but please assist.
Thank you!
Ethan

Hi Ethan.
Let me take a look at your video and I will comment back.
Thanks!

Thanks Craig – just to clarify, do you need me to download the video and send it to you?

Craig Staff replied 10 months ago

Hey Ethan.
So, I checked out your video. I went ahead and downloaded it and uploaded it myself, so I could compare the original without changes.
There is something unusual here. I see what you are saying, and I have never seen it before. They are slightly off.
So, let me dig further. I am wondering if it could be something with your video. Maybe some time sync issue.

Let me check further. Short answer is… no, this isn’t normal. Never seen this before unless there was something wrong with the audio and your audio is pretty good.

i will dig in a bit further and see what I can find.

Thanks Craig. Good to know this isn’t normal!

In case it’s helpful, I recorded it using the Loom app on MacOS, then downloaded it from Loom. So it’s possible there’s some processing there, but as you said, the audio is good.

Hey Ethan, I made a loom video for you as well. There is some timing discrepancy depending on the player the video is played in. https://www.loom.com/share/b82c518139a447919201b94fa7296d29 In Adobe Premiere it is one thing and in Quicktime another. Let’s hope it is just a fluke. If it happens on your next video reach out.  I can try to shift the time for you, but also we can dig in further to try to get to the bottom of it. Thanks!

Thanks Craig. One other thing – I recall that I used the Loom editor to trim off a bit of the end, could that have caused this discrepancy?

Ethan replied 10 months ago

Hi Craig, I just uploaded another video, and it has the same issue. It was also recorded with Loom, and this time I didn’t use the trimmer, so it was just recorded in Loom and then downloaded.

Could you please assist?
Thanks!

Yep. Let me take a look.
I will run a test with my own Loom video as well.
Will see if we can narrow this down.

Ok I just shifted the time forward about  a second and it looks to be fine.  I encoded the finished product too just to make sure it would be ok and it is.
So, this time when I put it into Adobe Premiere, the audio sync was way off as well (words didn’t match lips).  Which is a bit odd as usually if it is off, it would be off on CS too, but it’s just another indicator that something is wrong with the loom file.
So, I would do some research on Loom audio sync.  I believe there are settings you can put into place to make sure the audio sync is good.  Audio syncing is a typical issue with webcam video recording.
If you can’t seem to resolve it that way, I suppose I could put in a rule to always shift your subtitles forward, but I would try to fix it on the video recording end first if possible.  If that won’t work, just let me know.
Honestly, if it was me, I would record the video with my phone.  You will get better quality video and won’t have to deal with some of these issues.
Here to help.

Thanks Craig. If I used Zoom on my laptop to record it, do you think it might have similar issues i.e. its the webcam not the software?

Ethan replied 10 months ago

Just following up on the question above Craig, thanks.

Craig Staff replied 10 months ago

Ah! i thought I answered that. My apologies. Maybe I never clicked POST.
Possibly, but I can’t say for sure. If you are just wanting to record with your webcam another option would be OBS. https://obsproject.com/

It is mainly a streaming software, but I use it for recording also. Plus, it has the ability to adjust your audio sync. Now, I can’t guarantee that will work in your case, because usually when audio is out of sync it doesn’t match your mouth, and with your video, that was only the case when I looked at your second video in Adobe Premiere.

But it would be worth a shot.

It could be the webcam, the computer or the software, so not sure which.

Thanks Craig, I’ll give that a shot.
