RE: DVDSUB Subtitles - Tcon - 2025-03-02
Thanks! I see that now.
Like I said it's about every 5 seconds or so that I get a few bad frames in a row and then it goes back to normal. If you look at the license plate on the left you can see the loss in quality pretty easily.
I did just switch over to using my 3050ti to do the transcoding and the problem disappears. No more drops in quality. The problem is that this is hosted on my laptop and I'm trying to decide on a new dedicated server. I wanted to see if I could get away with a N100 or something cheap but seeing how this performed I'm wondering if I should get something with a dedicated GPU. I have a lot of DVDs with DVDSUB and other types that need to be transcoded and I want multiple people I'm sharing the server with to be able to use subtitles on those movies at the same time.
Thanks for the help!

One thing I missed from your initial ffmpeg log was that you don't have hardware decoding enabled. That shouldn't change the quality of the transcode, but it would significantly reduce the CPU load since it would offload that to the iGPU.
Not sure what is going on with the "double frame" in the transcode. I've never seen that on my Arc GPU.
Is the Intel graphics driver fully up to date?

Oh yeah I can enable hardware decoding and try it again. Maybe there’s a chance that improves it somehow. Yeah I just checked my drivers and they are all up to date.

I enabled hardware decoding and it looks like that fixed it! Thank you!

Glad to hear that fixed the issue, but wtf? I don't see why that would make a difference, but ok.
