In the Speedernet Sphere software, you can add 360-degree videos, with no weight or size limitations. On the other hand, the heavier your video is, the more your browser will have difficulties to read (in a jerky way) when broadcasting your experience. Therefore, we recommend using 2k videos with a size of 2048x1024 for low speed issue. In order to facilitate the encoding of your videos in the appropriate parameters, we advise you to use :
- HandBrake: An open source software that allows you to encode videos
- Media Encoder: Adobe Media Encoder is a video and audio transcoding software used in the Adobe Creative Cloud suite.
Start by downloading the "HandBrake" software: https://handbrake.fr/
Also download the "Media Encoder" software: https://adobe-media-encoder.fr.softonic.com/r (softonic.com)
Compress and re-encode a video with Handbrake
First of all, open the Handbrake tool and then drag and drop your media to encode. In case of encoding for multiple media, you will have to set up video by video, then add to the queue.
On the first "Summary" tab, select ".mp4", then rename the file extension to .mp4.
Switch to the "Dimensions" tab. At the top you will see the dimensions of the source, and at the bottom the dimensions of the export.
For a 360° view in Sphere, it is important to respect the 2 to 1 ratio.
Turn off the resolution limit, then specify the scale size.
If necessary, depending on the dimensions of your source, also turn off the anamorphic rule.
Finally, in the video tab, check that the encoder is in H.264 at 23, 24, 25 or 30 frames per second.
Select the average bit rate option, then enter a bitrate of 16000.
⚡ Please note that if after exporting, the video encoder encounters some slowness or bug, adjust the value to 8 or 10000.
Finally, deactivate the "2-pass encoding" and "first turbo pass" options.
You can then start the encoding, or add this file to the queue to set up the next one.
Compress and re-encode a video with Media Encoder
First, open the Adobe Media Encoder tool, or export your Adobe Premiere Pro or AfterEffects edit.
Select the video to be processed and then import it into Media Encoder. In the case of encoding for multiple media, you will need to set up video by video, then run encoding for the entire queue. Let's take a first video and import it.
Click on the video preset to enter the export settings.
Make sure the format is H264.
Then, in the video tab, set the dimensions, respecting a ratio of 2 to 1. In our case, we will choose a 4K resolution, in 3840 by 1920 pixels.
Then please check that the frames per second are 23.976, 25, 25, 29.97 or 30.
Then go to the "Bit rate" section, choose a 1 pass encoding, then set the target and max bitrate to 16.
⚡ Please note that if after exporting, the video meets some slowness or bug, adjust the value to 8 or 10000.
Close this settings window to return to the media list, then start your encoding.
