Hi!
Is there a practical solution to correcting sped up PAL video during playback?

MPC-HC menu > Play > playback Rate > 24fps

Additionally enable the internal audio renderer if you want automatic audio pitch correction.

I have an audio splitter question: there's this option "Prefer audio stream with highest quality".
The problem is (let's say the file has 2 audio track: DD ger [default], DTS-HDMA eng) if there's an audio track with default track, then that one will be used (DD ger tack).
So, is there any rules I can use for audio with which I can force to select the highest quality in this case as well (without specifying the language)?
Thanks

Despite you haven't upload screenshot of DXVA Checker 4.5.1 of your 3090 (and your recoded with some software (?) sample) I asked in my previous post try recoded your FX6 Sample.MXF in HEVC 4:4:4 FX6_Sample.mp4 (2,1 MB - so about 500 time smaller than original) https://yadi.sk/i/BqcTHKuM9dYM2g with CUVID and others. Despite it isn't loseless it'll may be hadware accelerated.

OK - I use MPC-HC for MPC-VR (some days ago SAT receiving program SmartDVB supports MPC-VR well too).

What command-line do you use for remux to get output with one (or several) audio track(s)?

PS. Did you try other than LAV Video Decoder like MainConcept (Demo) AVC/H.264 Video Decoder with turned off hardware acceleration in first string of its settings? I.e. my weak Athlon II x3 360 can't decode all 25 fps with LAV Video Decoder of this 20171205-014323_4KUA.ts (73 MB) https://yadi.sk/d/AnnpTSYKkoNkUg sample recorded by me from SAT but with MainConcept (Demo) HEVC Video Decoder despite of about 95% load of each of three core.
PPS. While Turing can HW decode in the centre of article https://developer.nvidia.com/blog/nv...ture-in-depth/ HEVC YUV444 10/12b HDR at 30 fps, H.264 8K, and VP9 10/12b HDR, I've uploaded FX6_Sample_25fps.mp4 (1,9 MB) https://yadi.sk/i/61fKGLxWBoUIyA if Ampere still the same as Turing in HEVC 4:4:4 and can't hardware decode 50-60fps at all.

No, "default" always overrides the selection, as the matroska specification mandates.

The option you named only influences ordering in absence of such a factor, ie. it would always use the first then if its turned off.

So it may be suitable to edit Matroska header flags to achieve your desired default stream selection for this specific file.

They have fixed DXVA2 AV1 in 9168. However, D3D11 runs faster, this is the preferred mode for Tigerlake.

Thanks, I forgot about default flag overrides everything, even the language selector in LAV splitter.

Yes, cheers, or I can use the language selector in the player (MPC-HC/BE).
