Hi, I am having issues rendering videos to Nvidia AV1/MP4 using Voukoder Pro.
Even though I set the Movflags to Faststart, this setting doesn't seem to affect the render in Adobe Premiere.
After render I don't get the usual extra delay while the atom is moved, nor does FFMPEG see the moov atom moved to the front.
Is that a limitation of AV1 encoding? Or did I just forget to change any additional settings required? Never had this issue when using h.264 before.
