Problem with square blocks (artifacts) in timelapse #1460

Closed Marchal1977 closed 2 months ago

Marchal1977 commented 2 months ago

Hi,

Noticed having square blocks in all of my timelapses (see attached screenshot of timelapse) blocks

I changed the FFMPEG Bitrate from 5000K to 20000, 30000 or 40000K, but no luck.

Any idea?

Thanks Marchal

Do you see those artifacts when viewing the video that comes out of indi-allsky, or is it when viewing the video on Facebook or another service?

Marchal1977 commented 2 months ago

The artifacts are already visible in indi-allsky itself, they are also visible in other players when viewed there.

Try adding -level 3.1 to the ffmpeg options on the Image tab in the config. Restart indi-allsky and try generating again. It might help, might not.

Marchal1977 commented 2 months ago

Going to try this, I will let you know the outcome!

Marchal1977 commented 2 months ago

Had alot of issues with re-generating (alot of QUEUED/FAILED attempts). After a full reboot/restart I got it working with one timelapse so far. I added -level 3.1 to the ffmpeg options. Now I will to wait until it makes a timelapse of its own the next day. Will keep you updated!

aaronwmorris commented 2 months ago

The default settings require you to first delete the timelapse before you regenerate it again. There is a setting on the Admin tab that allows you to directly overwrite and existing timelapse.

Marchal1977 commented 2 months ago

Cannot find that setting on the Admin tab...

this one?

aaronwmorris commented 2 months ago

If its there, it would be at the top of that tab, under the expiration settings. It was a recent update, so you may need to pull down the latest code.

Marchal1977 commented 2 months ago

have it running since August 2nd

aaronwmorris commented 2 months ago

Look like I added the functionality in #1446 on August 9th.

Marchal1977 commented 2 months ago

this one?

aaronwmorris commented 2 months ago

Affirmative.

Marchal1977 commented 2 months ago

Great! By adding -level 3.1 tot the FFMPEG options there are no more artifacts in the new timelapses!

aaronwmorris commented 2 months ago

Fantastic news! Let it run a few more days to make sure the clean result was not just a fluke.

Marchal1977 commented 2 months ago

Still clean! Thanks!

aaronwmorris commented 2 months ago

Great news! -level 3.1 is now a default setting in indi-allsky.
