[GUIDE] 59.94 progressive to 29.97 interlaced?

[Selur]

With mov output.
Using 'ProRes 422' I get:

Video ID : 1 Format : ProRes Format version : Version 0 Format profile : 422 Codec ID : apcn Duration : 1 min 14 s Bit rate mode : Variable Bit rate : 283 Mb/s Width : 1 920 pixels Height : 1 080 pixels Display aspect ratio : 16:9 Frame rate mode : Variable Frame rate : 59.940 FPS Minimum frame rate : 59.880 FPS Maximum frame rate : 60.000 FPS Color space : YUV Chroma subsampling : 4:2:2 Scan type : Interlaced Scan type, store method : Interleaved fields Scan order : Top Field First Bits/(Pixel*Frame) : 2.276 Stream size : 2.46 GiB (99%) Title : Core Media Video Writing library : Lavc Color primaries : BT.709 Transfer characteristics : BT.709 Matrix coefficients : BT.709

using 'ProRes 422HQ' I get:

Video ID : 1 Format : ProRes Format version : Version 0 Format profile : 422 HQ Codec ID : apch Duration : 1 min 14 s Bit rate mode : Variable Bit rate : 419 Mb/s Width : 1 920 pixels Height : 1 080 pixels Display aspect ratio : 16:9 Frame rate mode : Variable Frame rate : 59.940 FPS Minimum frame rate : 59.880 FPS Maximum frame rate : 60.000 FPS Color space : YUV Chroma subsampling : 4:2:2 Scan type : Interlaced Scan type, store method : Interleaved fields Scan order : Top Field First Bits/(Pixel*Frame) : 3.368 Stream size : 3.64 GiB (99%) Title : Core Media Video Writing library : Lavc Color primaries : BT.709 Transfer characteristics : BT.709 Matrix coefficients : BT.709

using 'ProRes 422 LT':

Video ID : 1 Format : ProRes Format version : Version 0 Format profile : 422 LT Codec ID : apcs Duration : 1 min 14 s Bit rate mode : Variable Bit rate : 202 Mb/s Width : 1 920 pixels Height : 1 080 pixels Display aspect ratio : 16:9 Frame rate mode : Variable Frame rate : 59.940 FPS Minimum frame rate : 59.880 FPS Maximum frame rate : 60.000 FPS Color space : YUV Chroma subsampling : 4:2:2 Scan type : Interlaced Scan type, store method : Interleaved fields Scan order : Top Field First Bits/(Pixel*Frame) : 1.623 Stream size : 1.75 GiB (99%) Title : Core Media Video Writing library : Lavc Color primaries : BT.709 Transfer characteristics : BT.709 Matrix coefficients : BT.709

using 'ProRes 422 Proxy:

Video ID : 1 Format : ProRes Format version : Version 0 Format profile : 422 Proxy Codec ID : apco Duration : 1 min 14 s Bit rate mode : Variable Bit rate : 88.3 Mb/s Width : 1 920 pixels Height : 1 080 pixels Display aspect ratio : 16:9 Frame rate mode : Variable Frame rate : 59.940 FPS Minimum frame rate : 59.880 FPS Maximum frame rate : 60.000 FPS Color space : YUV Chroma subsampling : 4:2:2 Scan type : Interlaced Scan type, store method : Interleaved fields Scan order : Top Field First Bits/(Pixel*Frame) : 0.711 Stream size : 787 MiB (97%) Title : Core Media Video Writing library : Lavc Color primaries : BT.709 Transfer characteristics : BT.709 Matrix coefficients : BT.709

No clue why they are detected as variable.
Playback seems sync.

Using mkv output, I get:

Video ID : 1 Format : ProRes Codec ID : V_PRORES Duration : 2 min 29 s Bit rate : 44.2 Mb/s Width : 1 920 pixels Height : 1 080 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 29.970 (30000/1001) FPS Color space : YUV Bits/(Pixel*Frame) : 0.711 Stream size : 787 MiB (97%) Title : Core Media Video Default : Yes Forced : Yes Color range : Limited Matrix coefficients : BT.709

output is async.
=> I'll look into it some more.
