【I need to add a custom option for transcoding frame rate】

[Kaouning 0]

My TV is quite old, but it can play 4K 30fps videos. My TV box (Google TV) supports up to 4K 60fps. When I play 4K 60fps videos, my TV experiences lagging visuals, but the audio runs smoothly. I have no choice but to transcode to a very low bitrate to watch them. In fact, a compromise could be made by choosing high quality and low frame rate to achieve the best experience. This should not be difficult to implement in transcoding, and I hope this feature can be added.

Kao,

Another method, often used online, is to have an alternate, lower res copies, available to play for users who run into bandwidth or server/network traffic limits.  When lower res media are made in advance and saved to the same directory, they can show up as a selection drop down in the media page: 4K 60fps, 4K 30fps, 1080P,  720P...

HI, yes I think some in-app control could help with this.

Pre-rendering more versions in advance can solve playback issues, but it will cause my storage pool to accumulate a large amount of additional data (hard drive prices have increased too much now). This is an optimal solution for large-scale server usage, but it is not the best choice for personal media library enthusiasts. This is because our NAS devices are usually replaced relatively quickly, and the latest chips have strong decoding capabilities, making online decoding very smooth. Compared to expensive products like TVs, the cost of upgrading NAS chips is just a fraction of the price of a TV.

Currently, mainstream online resources are all in 4K at 60fps. For someone like me who doesn't plan to replace my TV at the moment, this feature is essential to achieve real-time transcoding to 4K at 30fps, rather than simply compressing the bitrate to 1080p at 60fps or lower.I believe that in the future, 8K streaming media will need this feature even more, so you might consider including it in your update plans in advance.

Kao,

Good points.  4K 60 fps to 4K 30 fps conversion takes a fair amount of CPU or hardware encoder effort.  You would be staying to .mkv h.265 video codec plus whatever audio conversion might be needed.  Converting down to 1080P 30 fps would take less effort and you setup could handle more transcoding requests.  Also converting to .mp4 h.264 video is very likely for a lot of end users and it is a faster and easier transcoding, but h.264 is not a good choice to stay in 4K. Can you just record in 1080P and not bother having anything n 4K?  That would help with your hard drive and bandwidth issues.
