Hello.
I have some DVB-T recordings (720x576, H264, mpa, interlaced-TFF, YV12). I’m recording this stuff by using a USB-TVtuner + Windows Media Center. I then remux them (no re-encoding – only trimming) to .ts or .mp4 (using videoredo – question: can I open .wtv files in virtualdub?) for archiving purposes.
Sometimes I want to cut and edit (mostly deinterlacing) some small clips (~3 minutes).
I’m extracting the raw streams(H264+mpa) from the .ts files and then I’m using Dgavcdec+Avisynth+VirtualDub for editing.
This is my script :
LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\DGAVCDecode.dll")
LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\NicAudio.dll")
V=AVCSource("media.dga")
A=NicMPG123Source("media.mpa",normalize=false)
AudioDub(V,A)
AssumeTFF()
Trim(xxx,xxx)
QTGMC(Preset="Slower")
Crop(xx,xx,-xx,-xx)
I then open the script using VirtualDub, select ‘fast recompress’, Compression--ffdshow--(ff)HuffYuv and I’m creating an intermediate file.
The final stage : I open the huffyuv file with avidemux and re-encode it with the x264 encoder (setting the correct pixel aspect ratio – the pixels remain rectangular) creating an mp4 file. Question : What audio codec should I use, aac or mp3?
These are some samples from my recordings :
Tv series : http://dfiles.eu/files/pkjq8qhiz
Movies : http://www.easybytez.com/kj29jvyzke9i
Live Broadcasts : https://mega.co.nz/#!gAYFgC6C!eN0EPE00Qgk-5E38oLXoyXHGTuU_9bcEfUUitp4nfdE
(some of the clips have wrong aspect ratios - they are broadcasted this way)
Questions
1)How can I tweak the script based on these recordings? Can you make some comments about the quality of these clips (noise, colour etc)? I don't have any knowledge on the subject
2)Clip no.013 is a little bit weird (two aspect ratios)?
3)What is this black&white stripe on the top of the videos?
4)Some of the videos (like no.003 & no.010) don’t have black bars on the right and left. Does this mean they were shot with a digital camera? The aspect ratio of these videos is slightly over 4:3 and 16:9 ??
5) When i open some h264 files with DGAVCindex it says to me that the frame structure is MBAFF (what's this?). Also next to Colorimetry it says SMPTE 170M (is this correct?)
