  1. I was looking for users who have or have had/worked with Smart Renderer 5 from Pegasys, but of course any help from anyone would be appreciated. I am having trouble working with 4k video in Smart Renderer 5. I have a decently powered PC and I actually use Tmpgenc Works 7 (also from Pegasys) to edit 4k video with no problems. The problem is my frame rate drops considerable in Smart Renderer 5 to the point I can't work with it. Maybe some users have some suggestions. Thank you.

    How are your files encoded?

    I've used this for years.
    But I don't use it for 4K, nor really even HD all that much.
    Mostly use it to fix other people's H.264 mistakes, quick edit or audio re-encode.

    Some of my files are encoded with h.265 and others with h.264 usually in a MP4 or MKV container. Audio is always 5.1 AAC.

    Hmm... I could have sworn I read it worked with 4k. I was really hoping to use it but, I'm kinda glad I'm still in the trial period.

    It does. There are some OUTPUT specs that match what is being quoted.

    I wouldn't be surprised if H.265 files are boggy, but as I said, no problem here with H.264

    I am guessing when you say boggy you mean the program gets bogged down? Or did you mean buggy? If you meant bogged down by H.265 files, I guess I could try to reencode from H.265 to H.264 and see if that works. My H.265 1080p videos works flawless with Smart Renderer 5.

    I'm pretty sure there is a way to go from h.265 to h.264 losslessly using ffmpeg but, someone correct me if I'm wrong. If true, maybe the only downside would only be larger files?

  9. So I was able to convert from h.265 to H.264 using ffmpeg. I set the constant quality factor to 0 and kept the bitrate same as source. I THINK this gave me a lossless conversion but, the file size only went from 12 gig to 12.2 gig. I thought it would be like 20 times larger. I really see not quality difference whatsoever but I could be wrong.

    Of course, now I don't have 10 bit HDR. Its my understanding that H.264 can support 10bit but some adjustments have to be made at the container level?
