how can I remove interlaced lines from 1080p m2ts file?

[Tomaquet]

I have a blu-ray that has interlaced lines. I no longer have access to the original copy (I never saw it but assume it wasn't interlaced - I think it was a taken from a DCP or 35mm) so all I've got is this.

What is the easiest way to remove the interlaced lines? The original film isn't in the highest quality anyway so it won't matter too much if some of the quality is removed.

I tried some of the deinterlace options in VLC as a test but they didnt seem to improve it much. Does this mean if I re-encoded it with a similar deinterlace option, it wouldn't improve it anyway?

Thanks for any help offered!

(I have access to both PC and Mac)

You'll have to provide a sample of the video. And any real cleanup is probably going to require AviSynth. It's free but there's a big learning curve.

Do you know which (free) software can create a sample of a m2ts?

(Preferably for PC atm as the Mac is currently being used)

VideoReDo TV Suite has a free trial you can use temporarily to cut BluRay\M2TS\AVCHD, etc. Some use TSSniper but it's a little quirky to use and cuts only on IDR frames (key frames). There's also a trial version of TMPGenc Smart Renderer . Your MediaInfo reports says the video is 24fps progressive, which is BluRay standard for film speed video. A sample is important here, because it sounds as if your "progressive" video has blended frames.

Thanks for both your advice so far!

I've taken a sample from the video using VideoReDo, but a 1m20s sample is about 260mB. Should I upload it when it's so large?
Or should I re-encode it to a smaller size (but this means you might not notice the interlacing)?

(On my PC the m2ts sample doesnt play well. so I've also sampled it as an mkv which plays fine.)

[jagabo]

260 MB is fine with me. Do not reencode it. The point is to see the source exactly as it is.

By the way, a medium speed panning shot would be best.

[Tomaquet]

I made a slightly smaller/shorter clip (but not re-encoded)

There are no panning shots in the entire film as it's fixed in a car the entire time. But you can still see the interlacing when the background/people move.

Cheers!

(EDIT to include longer clip - didn't take so long to upload!)

Yuck. That started out as standard definition interlaced NTSC video. It was upscaled to HD and decimated to 24 fps. I don't think there's any great way to fix it but you could just blur the fields together like the attached sample. I'm going to try some other things later today.

[LMotlow]

Your mkv appears to be re-encoded at a different bitrate (? ?).
Looks like interlaced video, field-blended, then encoded as progressive. Some frames appear to be missing. I hate this stuff.

[johnmeyer]

Since it is not a one-of-a-kind collectible, just buy or rent the Blu-Ray or DVD and be done with it. It's not worth the effort to try to fix it.

[Tomaquet]

I have it on DVD (pal) as well. The people I'm doing a copy for insist on it being a blu-ray (They have the rights to it, just not a copy), but it doesn't exist in blu-ray (even the distributors only have it with foreign language subtitles hard coded).

Instead of trying to explain to them that the quality would be no different between a DVD and a blu-ray made from a DVD, what would be the easiest/quickest way of converting a DVD to blu-ray?

Thanks very much for all your replies so far!

[johnmeyer]

If you have it on DVD, and they insist on having it on Blu-Ray, then just up-res to Blu-Ray from the DVD. It will be much better than trying to do something with this source.

Could you give me a bit more guidance on how to do that please? (Preferably without spending on software I'll probably only use this once)

(what software would you recommend? On Mac, I've got Final Cut Pro 7, Compressor, handbrake and Toast. On PC, just free stuff.)

I'd rip the DVD with DVD Fab, upscale with AviSynth's nnedi3_rpow2(), then encode with x264.

I realise that Avisynth is powerful but it doesn't seem to be too user friendly. Is there anything that I could use? I'm not expecting the results to be anything special. As I said before, this is a one off thing for me - I doubt I'll have to do it again so I'm not that keen on the steep looking learning curve of Avisynth.

Thanks for your advice anyway.

I assume you have a Blu-Ray burner (if not, this whole conversation has no point). What software do you use when burning Blu-Ray discs? We can work back from that.

[jagabo]

VirtualDub, AviDemux, AviUtil, XMediaRecode, etc. can upscale.

At the end of this, somebody - you, the client, or their audience/buyers - are gonna be disappointed! They "have the rights" but can't get a copy? Sounds super fishy to me.

Yes. I've got a Blu-ray burner. To burn have used Imgburn (PC) and Toast (Mac).

VirtualDub, AviDemux, AviUtil, XMediaRecode, etc. can upscale.

Ok. Thanks. I'll take a look.

Well we could get a copy from the distributor, but with foreign language subtitles hard coded. That would mean having double subtitles which they'd prefer to avoid. The only thing fishy was the copy we paid for which was this rubbish!
