Sony HD-SR7 Output Conversion

[Verminaard]

Hello guys,

I have searched the forum but failed to find the answer to my question, so I am starting this topic. I apologize in advance if I've overlooked an existing topic that answers my question.

I do have the M2TS files and I am re-encoding them using x264 codec and MeGUI.

M2TS files that were shot by SR7 comes up 1440 x 1080i and I am using Yadif Deinterlace filter with Top Field First (TFF) option, resizing the picture to 1440 x 784 using Lancsoz sharp resize filter. Here are the related pieces from from the AVS file:

Load_Stdcall_Plugin("C:\Program Files (x86)\Tools\MeGUI\tools\yadif\yadif.dll")
Yadif(order=1)
LanczosResize(1440,784) # Lanczos (Sharp)
LoadPlugin("C:\Program Files (x86)\Tools\MeGUI\tools\avisynth_plugin\UnDot.dll")
Undot() # Minimal Noise
ConvertToYV12()

The output is nearly same as the original file because of my x264 settings but the FPS is 29.97 (normal for Interlaced NTSC file), I am curious if I also need to use (T)IVTC to drop it down to 23.976 and turn it into a progressive video? Will it poison the playback and make it unwatchable or the contrary? As far as I know, Interlaced NTSC videos not meant for IVTC, just trying to make sure.

Thanks to everyone in advance

yadif is a de-interlacer so it's already been made progressive. and it's not film so going to 24fps would be wrong. and just for better compatibility i'd resize to 1920x1080 or 1280x720. the 1440 source uses non-square pixels to create 16/9.

Thanks for the response.

Which one do you think is the best resizing filter to upscale from 1440 to 1920? Lancsoz4 (Sharp) or one of the Splines (16,36 or 64) when it comes to dealing with SR7 footage?
