How can I get GraphEdit to resolve a Quicktime lossless H264 4:2:2 4K file?

[GoauldGod]

So basically, I want to feed this file into an older program that won't read MOV files:

from MediaInfo:

ID/String : 1 
Format : ProRes 
Format_Version : Version 0 
Format_Profile : 422 
CodecID : apcn 
Duration/String : 30 min 24 s 
BitRate_Mode/String : Variable 
BitRate/String : 1 103 Mb/s 
Width/String : 3 840 pixels 
Height/String : 2 160 pixels 
DisplayAspectRatio/String : 16:9 
FrameRate_Mode/String : Constant 
FrameRate/String : 59.940 (60000/1001) FPS 
ColorSpace : YUV 
ChromaSubsampling/String : 4:2:2 
ScanType/String : Progressive 
Bits-(Pixel*Frame) : 2.218 
StreamSize/String : 234 GiB (100%) 
Encoded_Library/String : Apple 
Language/String : English 
Encoded_Date : UTC 2015-10-13 15:14:11 
Tagged_Date : UTC 2015-10-13 17:07:02 
colour_primaries : BT.709 
transfer_characteristics : BT.709 
matrix_coefficients : BT.709

So I'd normally use this flow for a run-of-the-mill video file:

GraphEdit to open the MOV file, feed into AVISynth to do resizing into 1080 + other processing, then into tmpgenc 4 xpress.

But GraphEdit won't resolve to it, and won't play in Windows video player.

Any new tricks I should try, or is the UHD video not workable? It WILL open in Xmedia Recode, but it doesn't author BluRay.

Do not use GraphEdit, use GraphStudio (Next) instead.

LAV Filters should have no problem with ProRes.

And since you're dealing with Avisynth, possibly FFVideoSource() (from the FFMS2 plugin) will give you better results than DirectShowSource().

You can use LSMASH to open Prores in MOV in an AviSynth script.

LSmashVideoSource("filename.mov")

Excellent! After going through a couple of hoops realizing that I've got a mix of 32-bit and 64-bit graphs and app fighting each other (for example, when avisynth complains of unregistered class when opening with a 32-bit app with a 64-bit graph).

Quick question: Does it matter if avisynth itself is 32 / 64 bit? Or does it only matter that both the graph and program are respectively 32 or 64?

I am going to mess with FFVideoSource now. Thanks again!

LSmashVideoSource("filename.mov")

How does LSmash compare with FFVideoSource? Any quality differences?

They have to match x86 with x86 , or x64 with x64

You're going to want to use x64 for UHD . Also faster

LSmashVideoSource does not require indexing for MOV/MP4 Iso base media container formats,

However it will open up 10bit in a stacked MSB/LSB format by default . Older avisynth classic used that hack to process higher bit depths

Recommended that you use avs+ , you can convert from stacked

Assuming you want to keep 10bit422
eg.

LSmashVideoSource("prores422.mov", format="YUV422P10", stacked=true)
ConvertFromStacked(bits=10)

FFMS2 will open up 10bit natively as 10bit planar without that extra step , it will be marginally faster . But the indexing step takes a bit of time at the beginning

No quality differences eitherway if you handle it properly
