TMPGenc Video Mastering Works 6 Deinterlacing settings

[magnu]

Hi there
I've downloaded the demo version of TMPGenc Video Mastering Works 6 & am hoping to fix up a video that I have a copy of which is wonderful quality, but is missing each second frame, which I think is down to the lower bitrate it has been saved in.

The video itself is in 4:3 & is 960x540. From what I can gather if I enter Deinterlacing settings I can make some changes to the video that may it play more smoothly, but as I don't do this sort of thing often, I'm not sure what settings I should change in TMPGenc in order to make the recording smoother?

[themaster1]

960/540 gives 1.778 in other words 16:9 and secondly i have a feeling your video is not interlaced, otherwise prove it with a picture. Mediainfo is a good tool to know a little more about your video

[magnu]

The video itself is in 4:3, and is an episode of Doctor Who, which has been downloaded from Britbox, whereas the actual file is 16:9. I used the ChrisPC software to get it, & this was at the highest setting the software has. I'm presuming the actual settings are how the episodes are being streamed on Britbox?

rookie mistake (i been there)
You should have captured 1080i (interlaced) unless you have deinterlaced the footage while capping. If not it's going to be a mess to fix and in any case subpar quality.
Upload a video sample when you can otherwise i'll not reply anymore in this thread

[LMotlow]

Many episodes of that program were created on film and are not interlaced. Likeley it's hard telecined and encoded as interlaced. As stated, we need a sample.

Upscaling SD to HD is a waste of time.

I grabbed the episode at the highest settings available, which was 1080i. I shall upload a clip later today which shows where the problem is.

Only one episode was ever created on film & has since been released on Blu-Ray. All of these episodes are from the classic series & were made on video. Many of them were released on DVD & were Vidfired. However, some of the early DVDs were of poorer quality of what has since been made available. They are of superior quality, though I doubt they have been also Vidfired, but I could be wrong? The only problem I can see is the low framerate, & when viewed it results in jerky motion.

[LMotlow]

Thanks for the correction about film -vs- video. All of he shows I've seen broadcast over here for the past umpteen years are telecined or use some weird frame structure for NTSC.

Upscaling SD to HD is a waste of time.

Here's a small segment from one of the episodes:-

If you grabbed the "1080i" version then why is this 960x540 pillarboxed ? There is a chance you can salvage that 1080i version if the fields are intact

That sample is already progressive and deinterlaced (1/2 the frames discarded) , and resized .

Since it's already missing 1/2 the information, nothing will really help. You can try to synthesize every 2nd frame with optical flow techniques, but it runs the risk of artifacts (some types of scenes it works ok, others it fails miserably)

[poisondeathray]

e.g. avisynth , mvtools2 / mflowfps , to "synthesize" every 2nd frame

https://www.mediafire.com/?deuu7nm12q6ybr5
(For some reason I can't upload clip directly to this site, keeps on failing)

It works ok in that sample clip with only minor artifacts, because there's not a lot of motion . But this is not really a representative clip of lots of scenes in typical Doctor Who . You would expect some scenes to fail a lot worse

When viewed on BritBox prior to download the 1/2 frames effect is still there. Others that I know of also downloaded the episode at 1080i, as they said it kept the image quality up? I can give it a go at the 720i settings & see how it looks? Don't know about the 960x540 though? Can only assume that's how BritBox are streaming it?

Maybe they are using a proper downloading method ?

The clip I grabbed was in 1080p

But the one you uploaded is not . Maybe you uploaded the wrong one ?

You should try for 1080i , or 1080p50 if they had that

What are you using to download ? Maybe there is a better method

Any software that will do that?

I posted an example in post #11 . It's free software (avisynth) , but there is a bit of a learning curve. There are other free options like msu frc in vdub , or paid options as well, twixtor (expensive), after effects are common ones

I'm using ChrisPC Video Tube Downloader. When I play the video on BritBox itself the artifact is still there.

[poisondeathray]

But when you play on BritBox, are there selectable settings or streams ? e.g. can you choose a higher quality one ?

If others downloaded at 1080i , then either they are misreporting, or maybe downloading from another site/source ? , or maybe you should try another method to download . I'm not familiar with BritBox, so I don't know what "works". Or try asking them what they used

[magnu]

The episode was downloaded in 1080p. TMPGenc must have changed it to 1080i? Others who have downloaded these episodes from BritBox also have 1080i versions (that may or may not have been 1080p prior?) but still have the artifacts.

[poisondeathray]

Was the sample you uploaded processed in any other way ? How did you "cut" the sample - "BritBox - Doctor Who Sample.mkv" ?

Let's clarify - by "artifacts" - you mean "not smooth motion" or 25p framerate - is that correct ? Not something else ?

There's no option for either, only 1080p or 1080p60

We've probably been posting at the same time (i've gone back and made some ninja edits)

Can you go back and re-read some posts above ? Especially the post about posting mediainfo report on the orignal download

I will send the MediaInfo stuff in a few hours, as I'm taking mum for a doctor's appointment. I'll also send the info for an MKV version of the file, uploaded to the net by a friend (The original download, before going through TMPGenc, is FLV).

This can wait...go take care of your mom


Those are all messed up 960x540 , 25p .

You need 25i (sometimes called 50i , but both mean 50 fields per second interlaced) , or 50p

So the "other people" were wrong about the "1080i" or they have different files that aren't represented here

There are ways to motion interpolate on just on playback too, for example svpflow / smooth video project

[magnu]

e.g. avisynth , mvtools2 / mflowfps , to "synthesize" every 2nd frame

https://www.mediafire.com/?deuu7nm12q6ybr5
(For some reason I can't upload clip directly to this site, keeps on failing)

It works ok in that sample clip with only minor artifacts, because there's not a lot of motion . But this is not really a representative clip of lots of scenes in typical Doctor Who . You would expect some scenes to fail a lot worse

Hi there. Only just had the opportunity to look at that clip & it looks great! I've downloaded AviSynth but not really sure how to go about using it, so if you are able to help me out or point me in the direction to a simple to use page on getting the settings to use to emulate more of what you have done to achieve the effect?

I've downloaded AviSynth but not really sure how to go about using it, so if you are able to help me out or point me in the direction to a simple to use page on getting the settings to use to emulate more of what you have done to achieve the effect?

A bit of a learning curve getting started with avisynth but it's not that bad really once you get started. There is some hassle collecting plugins and dependencies too, because many are developed by various people and distributed separately from the main install

Basic info on getting started
http://avisynth.nl/index.php/Getting_started

Basically you have to "load" a video with a source filter for each script. It's all done in text. You can do it notepad, save it, then change the extension from .txt to .avs . To preview scripts you can use virtualdub / virtualdubfiltermod or avspmod . In the example below, I loaded your sample video with ffms2, using FFVideoSource() . It's a separate plugin

https://github.com/FFMS/ffms2/releases
http://avisynth.nl/index.php/FFmpegSource


For this you could copy & paste and just change the filenames and paths for each video if you wanted to get it done quickly, then look into it in more detail at a later date or adjust some of the filters or settings to tweak the results

There are dozens of different optical flow/ interpolation scrips or variations. Some may produce slightly better or worse results in some situations, but they all fail, (and sometimes very badly, ugly artifacts) in other situations. The most common ones used in avisynth for general use are interframe, svpflow . They are based on mvtools2 as well. I used the most basic variant in that example, with just minor modifications to the overlap and search settings

FFVideoSource("BritBox - Doctor Who Sample.mkv")
source=last

super = source.MSuper(pel=2)
backward_vec = MAnalyse(super, overlap=4, isb = true, search=3)
forward_vec = MAnalyse(super, overlap=4, isb = false, search=3)
source.MFlowFps(super, backward_vec, forward_vec, blend=false, num=50, den=1)

You could have cropped the pillarbox if you wanted to (this is 4:3 content in a 16:9 frame). It would actually process and encode faster that way (fewer pixels). But I left them in for this exmaple

You need to encode the script. Avisynth is a frameserver, it doesn't produce audio or video by itself. There are various GUI's and CLI applications that have avisynth support

I used ffmpeg, but it's probably not user friendly to use when getting started. For me it's easier to do it that way, but there are GUI's that batch everything like encode video, encode audio, mux, all behinds the scenes. One reason I used it is because I wanted to stream copy the audio , instead of re-encoding it (avoidable quality loss) . So that script only contains video, no audio. When you use avisynth, it frameserves uncompressed audio and video, so generally you can't use "stream copy" with avs, otherwise you are copying uncompressed streams (massive filesizes) , not the original video & audio

ffmpeg -i input.avs -i "BritBox - Doctor Who Sample.mkv" -map 0:0 -map 1:0 -c:v libx264 -crf 19 -c:a copy output.mp4

The 1st input is the avs, the 2nd input is the actual video, but I'm taking the 2nd stream from the video, which is the audio . -map 0:0 means use 1st input, 1st stream (numbering starts from zero) . -map 1:0 means take 2nd input, 1st stream (so that would be the original audio). -c:a copy means stream copy the audio. -c:v libx264 calls the AVC encoder, x264 . -crf 19 is the "rough" quality level rate control. Lower values give larger filesizes
