Description

Summary of the bug:

When using the zoompan filter and setting any x or y (or both) value, the effect is shaky and jerky.

How to reproduce:

 ffmpeg -framerate 25 -loop 1 -i in.jpg -vf "zoompan=z='min(zoom+0.0015,1.4)':x=50:d=150" -t 6 -s 640x380 out.mp4

Reproduced by developer: set
Status: newopen

Workaround is to insert the scale filter:
-vf "scale=hd720,zoompan=z='min(zoom+0.0015,1.4)':x=50:d=150"

Do you know why this issue wasn't reported earlier to the developers?

comment:3 by slhck, 9 years ago

Ah, is the reason that the rescaling is done after filtering otherwise?

Not sure why it wasn't reported. I had not seen the old question raising the issue, otherwise I probably would have posted a report earlier.

comment:4 by slhck, 9 years ago

A similar thing happens with video – the output is shaky and lots of frames are dropped. (Could only test on recent stable though.)

Inserting the scale filter before (as Carl-Eugen suggested) with video magically makes the output 720p, without me requesting that.

When I use ffplay it shows everything correctly though:

ffplay test.mp4 -vf "zoompan=z='min(zoom+0.0015,1.5)':d=125:s=640x320"

Priority: normalimportant

Could anyone working on this problem. Scaling didn't fix problem in whole. Also, when using scaling encoding time progressive growing. Without zoompan component ffmpeg is unuseful in my case.

Priority: importantnormal

Changing priority back to normal – this doesn't classify as an important bug, in my opinion.

comment:7 by xavierts, 5 years ago

Any new workaround or fix for this issue? I am still able to reproduce in 4.0.2. Scaling beforehand consumes a lot of memory for 4k+ resolutions.

comment:8 by Jim DeLaHunt, 5 years ago

I suspect there were some errors copying and pasting the original "how to reproduce" command and output. It reads,

 ffmpeg -framerate 25 -loop 1 -i in.jpg -vf "zoompan=z='min(zoom+0.0015,1.4)':x=50:d=150" -t 6 -s 640x380 out.mp4

First, the command line has the output size setting -s 640x380, but the command output says "output #0" has size 640x360, as does also the supplied "out.mp4" file. 380 is different than 360. Second, the command line specifies an input file named in.jpg, but the command output says the input is read from 'out.jpg'. "in.jpg" is not "out.jpg". If there are mistakes here, are there mistakes elsewhere?

Replying to slhck:

Inserting the scale filter before (as Carl-Eugen suggested) with video magically makes the output 720p, without me requesting that.

ffmpeg -i test.mp4 -vf "scale=640:360, zoompan=z='min(zoom+0.0015,1.5)':d=125" out.mp4
[... omitted for brevity ...]

The 720p output is expected. Note that the '''zoompan''' filter defaults to an output image size of hd720, unless the invocation asks for a different size by means of the s option. For a proper test, this command should be revised to
ffmpeg -i test.mp4 -vf "scale=640:360, zoompan=z='min(zoom+0.0015,1.5)':d=125:s=640x360" out.mp4

One of the example zoompan filter invocations in the documentation demonstrates setting the output size this way.
