Green stripe across top of preview window

Videosync

HI,

Im getting a weird issue where there is a green stripe across the preview window whenever I play a movie file in the arrangement page. Is this an issue with the codec?

Thanks

Charlie

Hey Charlie. As far as we are aware, this only happens on Windows. What codec are you using for this particular video, and what is the resolution of the video? Would you be able to share the video with us?

Hi,

here’s an example video

Hey Charlie, thanks for that! What I meant to ask actually is if you could send that original video, the one that shows the green bar at the top of the Videosync window. :slight_smile:

Here is a similar example

Inrterestingly, I just bounced a video animation out of from davinci resolve fusion and then imported into ableton for videosync and there is no green stripe across the top of the screen

I’m having the same problem. Is there any solution? I want to buy the license but hesitant. Thank you.

Hi there! Welcome to the forum and thank you for reporting this issue. This seems to have to do with this change mentioned in the release notes for Videosync 2.1.10:

  • Videosync now uses hardware-accelerated video decoding on Windows where supported, so video clips on Audio Tracks appear more quickly and CPU usage is reduced.

Until we resolve the issue in a future update, you can download Videosync 2.1.9 here.

Apologies for the inconvenience!

Hi Jean-Paul and everyone,

i have the same issue as well. Windows user. As a workaround i’m currently playing videos from simpler: from there no problem.

I don’t think i’m downgrading because the hardware acceleration upgrade is so good! Changed the performances and my pc fans stress drastically. Hope you will find a solution though.

I love Videosync btw!

I am also evaluating if I should buy. I will be waiting until the issue is resolved as I too want to take advantage of the hardware acceleration.

FYI, I expect green/purple lines only to appear when using video clips with heights that are not divisible by 16. 1080 for example does not result in a round number when dividing it by 16, while 720 does. If you need to work with a resolution of approximately 1920x1080, exporting your videos with a height of 1088 is a possible workaround, albeit it a very inconvenient one.
It’s a complicated issue on our end, and we hope to resolve in the not too distant future.
