Is it possible for display in VR-Headset (separate vids for each eye) to create TopBottom/OverUnder from two streams (videos for each eye) inside a 360-Video? My application only accepts 360 Videos topbottom for stereo, and I need to display a standard stereographic video (Ego Qoocam) and have already separated video streams. If yes, how to set the pixels in Filter “Size Position” etc.?
This works nicely; I figured out how to set the pixels in the filters “size…” for the two tracks, have a third transparent track to place the two videos on; resulting in a 3d-mp4-File that is nearly 1 GB and stereographic.
BUT the resolution is too low. When I redo the rendering with new values for 7680X7680 and export it, I receive a file of only 300 MB - and that does not play. Why is it so small (and inoperable)?
What export settings did you use?
Also are you using hardware acceleration? Some GPUs have a strict limit on max resolution.
Try to export a 10s portion (using a range marker) and see if that one plays correctly.
It might also help right click → view log on the export job.
Thank you. No HW-Encoding possible, I have a Ryzen 7 5800H, 16 GB RAM, GPU on RTX3060, 6GB VRAM.
SW-encoding (10 seconds duration video ) works now on Gaming Laptop but warnings,
Need to learn info on right-click report first, e.g. many " [swscaler @ 000001bedb533080] deprecated pixel format used, make sure you did set range correctly"
We only need to demonstrate that it works technically (and experience-psychologically!). Production will later be on dedicated machines.
Presently processing time is not relevant - do I need more RAM for longer videos (1-2 minutes) or a better CPU?
You can ignore this one, I see it all the time.
I did 2 quick tests:
- one with only a color clip and for me it uses 22GB of ram at 7680x7680 using CPU encoding.
- another one with 7680x7680 but included an 8k video from my phone + 2x 4k videos from a previous export and I see 100% RAM usage (32GB installed, 22GB actively used by export) + page file commit size of 45GB (I think this includes real RAM). It slowly went up but I stopped the export after 5 mins at 20%. Estimated time was 35 mins - for a 1 minute project.
So definitely way more RAM for you, a slower CPU just takes longer to encode but won’t create an error. Also keep in mind the 7680x7680 resolution might not be playable by the device you want to use. I’d stick to 3860x3860 4096x4096 and increase quality in the export tab to 65%.
Btw, just playing back the 8kx8k video uses 5GB ram for me (in MPC-HC, VLC freezes the image and Movies&TV app just shows unsupported format error).

Thank you very much! Integrating and expanding on your information I started to understand a lot of the subject. I especially learned about the dependencies of reslution in pixels, pixels per degree of vision and subjective immersion and how to use computer hardware.
Happy Holidays!
