Struggling to De-interlace a 25i H264 file to 50p on Windows - Totally lost

[bergqvistjl]

I have a file (.ts container, H264 25i video, AC3 audio) where I would like to de-interlace the video stream (using QTGMC or yadif, which ever is the better quality) to 50p - at the original resolution & in the same H264 codec. I would like to leave the audio stream untouched from the original. How do I do this?

I've tried with MeGUI but frankly its so confusing that i'm just lost... I've tried looking around on the net and the guides that i've seen seem out of date or maybe i'm doing something wrong?

I'm running Windows 10 64-bit. Where do I start? What's the best tool to use?

Use the File/Open menu to open the TS file. MeGUI should offer to index it. Add the indexing job to the queue and run it. When it's done, the Script Creator should open with a preview. Switch to the Filters tab, enable de-interlacing, select "interlaced" as the source type and "Yadif with Bob" for de-interlacing. When you've finished setting up the encode save the script and it'll be loaded into the video section.

That should get you started. I generally save the script, add the video encoding job to the queue and run it (after configuring the x264 encoder). When it's done, I open the encoded video with MKVMergeGUI, add the source file (the TS file in your case) de-select the original video stream and remux that as an MKV containing video and audio. There's several ways to output a completed file, but if you're using x264's CRF encoding (quality based) and therefore not aiming for a particular file size, that's fairly easy (assuming an MKV is okay), especially for file types where the file indexer can't extract the audio stream (in which case MeGUI has to re-encode it to output a completed file).

QTGMC will be better quality than Yadif, but it's very slow and a whole other thing. I posted instructions for installing SRestore and QTGMC for someone here which may help you (SRestore and QTGMC are different things but he needed both and they have plugins in common). There's a list of plugins newer than those in the QTGMC plugins package I linked to here. Or..... I think StaxRip and Hybrid both come with the ability to de-interlace with QTGMC.

perhaps ffmpeg?

@SET x264opts="pic_struct=1:aud=1:force_cfr=1:threads=auto:no_psnr=1:no_ssim=1:bluray_compat=1"
@ffmpeg -i %1 -c:v libx264 -x264opts %x264opts% -x264-params %x264opts% -preset medium -crf 20 -tune film -profile:v high -filter:v "bwdif=mode=1:parity=-1:deint=0" -c:a copy %~n1_.mp4

perhaps you can use nnedi - it was implemented on ffmpeg quite time ago...

I'd just use QTGMC with 'InputType=0' (which it defaults to anyway).

As for audio, demux it first, and just let your AviSynth script process the video first. And then remux the 2 again afterwards.

I really don't find any of the indexers to work well with H.264 in a .TS (FFMSIndex/L-Smash for MeGUI). In my experience there is always rouge decoding errors in random spots, like it's skipping frames. Anyway to over come with I always mux H.264/.TS videos into .MKV, which tends work without issue.
