Apollo squares!

Whoa! Apollo (v. 3.1.9) suddenly starts to divide the scene up in odd squares at certain spots! It’s unsuable in this state.

Honestly, this sucks. :frowning: The frame interpolation processes take ages to complete. In Europe (where I live) pulling 450W+, for over 24 hours. costs a pretty penny these days, as electricity prices have skyrocketed since the war in the Ukraine. Having to toss your video job, half-way thru, because you detect an egregious error, is less fun than one might think.

@meimeiriver The Apollo model is recommended when creating a slo mo output at a factor of 4x or more. I would switch to Chronos Fast for this use case.

We are working on a new frame interpolation model which can be accessed by joining the Video Beta Tester.

Thanks for getting back to me. :slight_smile: I already tried it with Chronos Fast, but that yielded the following error (also reported in Beta):

floor mishap

And I am already a beta tester, btw. :slight_smile: Is new Apollo in the new alpha version?

that contradicts your post , where you guys state that Apollo should be used for anything below x8, including x4 and x2
which one is correct? your statement here or the post?

Hmm, saying they’re ‘quite satisfied’ with their frame interpolation, is quite disturbing, honesty. I alone sent them 2 samples of egregious frame interpolation errors, both in Apollo and Chronos Fast – the kind of errors that make you need to throw away the resultant videos.

The official reply, “I’ll switch to Chronos Fast” is a denial of Apollo, and there is no commitment to fix Apollo, Topaz probably thinks that frame interpolation is the treatment of single-scene fixed shots.

If it is the old Apollo, although the effect is worse, there is no color shift and no blocks, so you don’t have to worry about any unexpected downgrades; the later Apollo, which doesn’t care about color shift or the blocks in the transition, can also be used; the current Apollo, any position there may be squares, I will not use them.

It is in v3.1.7b (Apollo soft) :slight_smile:

Not at all the case :slight_smile: We are constantly training models and are aware of several frame interpolation issues which we are working to correct. We have a new model in Beta that may replace one of the current models.

Apollo pecializes in non-linear motion and slightly blurry inputs. Generate 8 interpolated frames per run.

Only recommended when slowing files down by 4x or 8x.

I have the same issue with Apollo. Whenever there is different levels of brightness in an image, the image turns into blocks. I tried to flatten out the image in Resolve with a reversible gamma shift to see if that would solve the issue with Apollo, but it did not. Is there any sort of fix for this at the moment? Any tweaks I can do (in Topaz or ffmpeg)? The results would be exactly how I wanted if it weren’t for the blocks (all I need is a smooth transition from one “block” to another). BTW I do not see “Apollo Soft” as an option in v3.2.1 on Mac ARM nor when I tried v3.1.7.

Just wanted to give a quick update and let everyone know our developers are aware of these issues with Apollo and we are working on identifying the cause and pushing out a fix. Thank you for your detailed bug reporting and let me know if there’s anything else I can help with!


Has there been any progress on this issue? Just want to know before I begin another render.

For those of you who are still experiencing this issue with the exported file, can you please upload the input & export files? This issue was rolled into another similar issue and we have determined that they are not connected. Any files you would like to share would be very helpful!

In my test case the blocks only exist during transitions, not sure if it’s the same topic as this one. For my test case, I submitted twice.

Thank you!

Is there a certain way to send you the input/exports? Or should I just upload to Google Drive and then send you the link?
