Color change on encoding

[Selur]

Starting with a resetted Hybrid (reset Defaults), enabling all Warnings, loading your source, setting 'FFV1' as encoder, creating a job with mkv container and then closing Hybrid.
I, too, see:

.... <HybridData name="mkvColorMatrix" value="BT709"/> and <HybridData name="mkvColorMatrix" value="GBR"/> differ. <HybridData name="mkvColorRange" value="Broadcast Range"/> and <HybridData name="mkvColorRange" value="Unspecified"/> differ. <HybridData name="mkvColorTransferCharacteristics" value="ITU-R BT.709"/> and <HybridData name="mkvColorTransferCharacteristics" value="Reserved"/> differ. <HybridData name="mkvColourPrimaries" value="ITU-R BT.709"/> and <HybridData name="mkvColourPrimaries" value="Reserved"/> differ. ...

This is correct, since these are setting that changed.
For example, the default:
"<HybridData name="mkvColorMatrix" value="GBR"/>"
changed to
"<HybridData name="mkvColorMatrix" value="BT709"/>"

You told Hybrid it should report any changes, and thus it does.
If you don't want this, do not enable all warnings.
This has nothing to do with color changes.

Using 2024.11.11, loading your file, setting FFV1 as encoder I get:

Input #0, matroska,webm, from 'g:\Output\250frames.mkv': Metadata: ENCODING_GUI : Hybrid 2024.11.10.1 ENCODER : Lavf61.9.100 Duration: 00:00:10.43, start: 0.000000, bitrate: 156854 kb/s Stream #0:0: Video: ffv1 (FFV1 / 0x31564646), yuv420p(tv, bt709, progressive), 1920x1080, SAR 1:1 DAR 16:9, 23.98 fps, 23.98 tbr, 1k tbn (default) (forced) Metadata: ENCODER : Lavc61.24.100 ffv1 BPS : 111312176 NUMBER_OF_FRAMES: 9303 NUMBER_OF_BYTES : 5398821425 _STATISTICS_WRITING_APP: mkvmerge v88.0 ('All I Know') 64-bit _STATISTICS_WRITING_DATE_UTC: 2024-11-11 04:21:23 _STATISTICS_TAGS: BPS DURATION NUMBER_OF_FRAMES NUMBER_OF_BYTES DURATION : 00:00:10.427000000

Strangely, when I look at the file with mediainfo it reports a wrong length, frame rate and size values for the video.

Video ID : 1 Format : FFV1 Format version : Version 1 Codec ID : V_MS/VFW/FOURCC / FFV1 Duration : 10 s 427 ms Bit rate mode : Variable Bit rate : 111 Mb/s Width : 1 920 pixels Height : 1 080 pixels Display aspect ratio : 16:9 Frame rate mode : Variable Frame rate : 892.203 FPS Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Compression mode : Lossless Bits/(Pixel*Frame) : 0.060 Stream size : 5.03 GiB Writing library : Lavc61.24.100 ffv1 Default : Yes Forced : Yes Color range : Limited Color primaries : BT.709 Transfer characteristics : BT.709 Matrix coefficients : BT.709 coder_type : Golomb Rice

You do see different color right? You are not just relying on what mediainfo reported, correct?

=> Does the new 2024.11.11 start for you?
