Question / Help OBS Recordings Becoming Slideshows (+misc questions)

[DesolatePsyche]

So first, to the main Issue. Yesterday, I recorded "Layers Of Fear" for 72 Minutes, but the whole video was basically a slideshow. Meaning that video ran showing picture, after few seconds changing the "picture" or simply put in another words, video wasn't something I would call a video. Today I recorded AGAIN.. for 40 minutes, all was fine, until last 15minutes became a slideshow again. I will have to rerecord another day again now.. Anyhow would Like to know the cause for the issue and how to avoid or fix it altogether.

Misc Questions

Opinions regarding my OBS settings and rendering settings.
Output > Recording
Format .mp4, Encoder H264/AVC Encoder (AMD Advanced Media Framework) ; Quality Preset - balanced ; Rate Control Method - CBR , PrePass Enabled, Target Bitrate 25000, Filler Data Enabled, Keyframe Interval 2,00; Audio Bitrate 256
Audio
Sample rate 48khz, Stereo
Video
Base canvas 1080p, output 1080p, Downscale filter - Lanczos (sharp, 32sample), FPS - 60
Advanced
Rendered DX11, Color Format NV12, YUV Color Space - 709, Color Range - Partial

Rendering settings
Project properties
1080p, 59,940 FPS, Field order none, pixel format 8bit, full-res rendering quality - best, motion blur type gaussian, deinterlace method none, resample disabled. Audio stereo, 48khz, 16bit depth, best quality.

Render settings (rolled with 60fps 720p as file sizes and render times are unreal)
MainConcept AVC/AAC, 720p frame size, high profile, 59,940 framerate, field order none, pixel aspect 1,...., ; number of reference frames 2, deblocking filter unchecked, 10kbps bitrate (10000000) CBR, Number of slices 1, Encode mode (use OpenCL if available), Enable Progressive download - checked

Audio - 48khz, 192kbps bitrate.
Project - best render quality.

1 Hour and 3 Minutes Video took around 6.5Hours to render. (4.6gb file size)

So any recommendations and opinions regarding OBS , Render settings and so on are welcome.

Did today another 1 hour long session to and when I stopped finished recording (pressed stop recording) It was in "stopping" status and bottom bar had text "encoding overloaded" .. and once it finished saving, I got another recording that ended up as a slideshow. Very frustrating.

Output > Recording
Format .mp4

Automatic fail as far as I'm concerned. MP4 is the LEAST reliable recording format of the ones that OBS supports output to. If ANYTHING causes the recording to terminate in a non-graceful manner, the ENTIRE recording is lost.

Encoder H264/AVC Encoder (AMD Advanced Media Framework)

Problematic on your system. Your log shows you having major performance issues on the video card.

Rate Control Method - CBR

Not good for recording. This causes either a LOT of wasted disk space (if your bitrate is set too high for your content type) or a LOT of pixelation (if your bitrate is set too low)
Use CRF or CQP based bitrate selection with a value of 14.

If you're not using multiple audio tracks, use:
Simple output mode
Indistinguishable recording quality
FLV format
Software low cpu use or the amd encoder.
