Good morning. I get the attached issue when the animation of finished and I got play it back and it’s an MP4. Any idea what the issue is.
It looks like the file is corrupted. What is the file size, is it very low? Was it saved on a local or network drive while rendering? Does it work with other media players?
Thank you for the reply. The file size is 9mb, only a low rez test. The file is saved to same machine my main machine I always use, It has never happened before. No it will not open in anything other than Chaos player. i dropped in to that to see it.
Can I send you the mp4 , I don’t understand whats wrong. need to get the Animations out to a client.
You can send it to me ( nikola.goranov <at> chaos.com ) but I don’t think I can fix the file. You will probably have to re-render. My hope is that it’s a one-off random corruption. If you’re worried about committing to a long render again, try a second or two of low sampled animation first and then go for the full length.
Well, good news: it seems it’s just the codec. We added AV1 support to our latest release, it’s a new and better codec (we used H.264 before). The file opens fine in my VLC 3.0.20, and also in Windows “Movies & TV” app and Windows media player after I installed the AV1 codec from the Microsoft store (screenshot below).
If you’re worried about your client not having a compatible player etc., you could disable AV1 from Preferences->General. H.264 will be used instead. You can verify which codec was used in VLC from Tools->Codec Information.
Yes thank you very much, I have disabled the Av1 from preferences. Thank you. Cart before the horse as they say.
All good now. Thank you for sorting so quickly.
Phil
