Dear developers: Can you give me a detailed standard parameter about H.265/HEVC ovcopts video resolution parameters? I will be very grateful.
I want accurate and high-quality video parameters for various videos, for example: 2K 3K 4K 5K 8K.

Dear senior developer, I don’t have any LOGO pictures on my D drive. I want to test whether the watermark can appear. How should I add the watermark to the video? Do I want to put the LUGO picture into the D drive and change the suffix to .png to realize the video watermark?

Senior developer, I don't quite understand what you mean? Does it mean that my D drive does not have LOGO watermark text? Can you give me an example? Be more detailed, thank you infinitely

I have tried to switch to the "advanced" mode, put something like "zscale = transfer = linear, tonemap = reinhard, zscale = transfer = bt709, format = yuv420p" into the lavfi field, set the depth = 8 bits,
But every time the effect appears, it is displayed incorrectly and cannot be converted at all. I would be very grateful for answers.
The following is the error log content.

Dear svp team, can you elaborate more?  How do I set SVP to perform tone mapping when transcoding HDR video? I don't know where to set it or how to write the code. Please tell me the detailed steps.

Could the great team of SVP reply me, why did the HDR mode disappear completely after I transcoded the HDR movie? what happened? Does SVP support HDR video transcoding? I am very worried. I like the HDR of 120FPS movies after transcoding. My requirement is to transcode movies at 120FPS+HDR. I hope the great SVP team can help me solve my troubles.
