Hi Frans,
I recommend to use "Quality" mode in PTE AV Studio and choose the "High quality" preset (100% in Custom mode). This is the best choice for all types of content - animated slideshows or dynamic video footage. Video encoder automatically allocates bitrate, assigning high bitrate to dynamic scenes with video footage (or animated pictures) and low bitrate to static photos. The automatically calculated bitrate can vary from 0.7 Mbit to 60 Mbit. For example, the Sample Project at 1920x1080 (HD), 60p has an average bitrate of 8.6 Mbit. You don't waste bitrate unnecessarily - it increases only where needed, maintaining constant visual quality.
This is similar to saving a JPEG file when you specify the desired compression quality, for example "9". The file size will differ depending on the complexity of the image details and its dimensions.
If you still prefer to set the bitrate manually, use these values as a guideline:
HD (1920 x 1080), 60p:
4-8 Mbit - for animated images
10-16 Mbit - for mixed content or dynamic video content
4K (3840 x 2160), 60p:
15-30 Mbit - for animated images
40-60 Mbit - for mixed content or dynamic video content
Also avoid hardware encoders for best quality.
Important note: Bitrates from video files recorded by professional cameras or smartphones should not be used as a reference. They use simplified hardware encoders (works in real time) that don't utilize bitrate as efficiently, so manufacturers compensate by significantly increasing the bitrate.
