CODECS and File Size + GPU

[hektor314]

Hello
I use bandicam

Can somebody help? I record mainly charts on on different timeframes on 4K display. But my GPU 5500xt is limited to 5k resolution (VSR).
Bought 3070 rtx but it have bad drivers because from time to time looses signal somehow. (Screen turns off and on.)

Want to buy

Radeon 6800xt for 8K VSR recording on my 4K screen. Use currently those settings:

file type
mp4.

1 Fps

codec
H264 (AMDVCE/VCN)
quality 100

12 hours of recording gives me with those settings only 300mb file size.

The question is.
Will I get better quality recordings when I buy
Radeon 6800xt?

Iknow i can go cheaper on older cards but this one is more versatile and future proof.

This card have:
4K H264 Decode
Yes
4K H264 Encode
Yes

OR

Radeon Pro W5500?

Because:
https://www.amd.com/system/files/docume ... asheet.pdf
its have better those specs:

HEVC Encode (up to 4K)
HEVC Decode (up to 8K)

W5500 is rdna1 and 600xt is rdna2

What HEVC Decode (up to 8K) really gives me?

Will I get smaller file size, better qualty with W5500?

Thanks for answers.

buying a better doens't specificly means better video quality.
correct me if i am wrong but 4k is just 4k and 1080p is just 1080p
and bandicam isn't the best screen recorder i suggest OBS

 

[hektor314]

Yes but the gpu or whatever codecs are used can have some improvement from generation of graphic card to other.
Thanks for the answer. But OBS cant recover file when comp crashes. This is only reason I use it.

I'd be using the built-in Radeon recording or OBS. If your computer is crashing a lot that should be your first priority. Bandicam over the years hasn't seemed to get better.

How you can get your file back after reboot when obs have corrupted file? Thanks.

That's not a driver issue, that's a Displayport cable issue. Clean your ports with compressed air, make sure cable snapped-in in both ports, and if it still sporadically loses signal - just get a different cable. Had the same crap on my 4K Samsung.
Forget about switching GPUs, your RTX3070 is more than capable to do everything you need and more.
Also, bandicam is garbage. A piece of outdated software with outdated pricing model.
I'd switch to OBS, if you need something decent. Personally I cling to NVidia's shadowplay just for convenience (even for desktop recording).

But OBS cant recover file when comp crashes. This is only reason I use it.

That's a weird requirement... Why would you crash it? If you want to record overclocking sessions, you should probably use an external capture card and a second PC/laptop. Not a single piece of recording software out there can guarantee file integrity after BSOD or forced reboot, even bandicam. Only if that software records in small chunks, but that's just stupid.

I was doing DSR NVIDIA up to 8K on 3 displays and on all of them was random switching on and off. Checked everything on alll ports and cables comes with monitors so its not cables fault. Because on my 5500xt i had 5k on all of them and it was perfect - no issues. Was naive and thought when I buy 5700xt xfx I will have 8k like with 3070 but did t know amd have a cap for VSR up to 5k. Though specs for 5700xt says it can do 8K signal at 60hz digital. But amd cant do VSR up to 8K.
So I m gonna now wait till 6800 comes out. and try vsr 8k again. Bought 5700xt 3 days ago and now I listed it on ebay to sell fast. If not its going back to ebuyer.

If you want best quality use CPU/Software H264 with as much as bitrate possible.

If you don't have a fast high core CPU only then use GPU/Hardware-accelerated H264. But even then it can't match CPU/Software quality-wise.
Some options are Intel Quicksync if you have an Intel CPU with iGPU (any Intel cpu except the ones with F suffix e.g. Intel Core i7 10700KF), Nvidia NVENC and AMD VCE. Intel Quicksync and Nvidia NVENC is best. AMD VCE a distant last in terms of quality and even software support

Late p.s. And o yea OBS isn't the problem with recording corruption when unforeseen circumstances happen. It's the container aka MP4. Always choose mkv when recording: Should you be recording to MP4 with OBS? — OBS Mythbusters | by Jessica Alouette | Medium

8K DSR on three displays? WTF are you doing with this stuff anyway? With this ^^^ and mentioned earlier random BSODs I'm not even sure whether you are trolling, or doing something extremely weird that even my miswired brain can't understand... Why use DSR in the first place?
