MTS to MOV without reencoding (Windows platform)

[Stears555]

Hello Guys!

Have you any idea about a video converter, which can transform MTS (camcorder) fileformat into Quicktime MOV format without reencoding the video file (direct-stream copy) on Windows platform?

Thank You for Your reply!

You can use ffmbc command line , or a batch file

eg. this will batch re-wrap all the .mts in a directory to .mov

for %%a in ("*.mts") do ffmbc -i "%%a" -vcodec copy -acodec copy "%%~na.mov"
pause

Hello!

Are there any other way to transform MTS to MOV?

I tried mediacoder, it transformed MTS (progressive segmented frame) to MOV with direct stream copy, however the lenght of the output video was two times longer than the original.... therefore it was wrong.

When i set "ffmbc" as video encoder in mediacoder, it created tiny 5 megabyte files-------

There might be other ways, but you'll probably get other errors or wrong framerate such as mediacoder (which uses ffmpeg, not ffmbc) . Nearly all free utilities are based on ffmpeg, will have the same bug

You can keep on doing trial and error, or use ffmbc which will work with "30p in 60i" AVCHD

And why would you want to re-wrap to MOV on a PC ? It can cause problems, gamma shifts, playback issues, crashes in many Windows programs . MOV is a more suitable container for Macs

Because of Progressive segmented frame problem. There are two types: malignant PsF and
Benign Ps.

I have a Canon camcorder with Malignant PSF (( and Windows 7 X64.

• Benign PsF: a method of recording progressive video in an interlaced stream in such a way that modern video editing programs can automatically detect that it is truly progressive video which has simply been “disguised” as interlaced video.
• Malignant PsF: a method of recording progressive video in an interlaced stream in such a way that even the most modern video editing programs are fooled into believing that the footage is actually interlaced. If not compensated manually by the editor, malignant PsF can be subject to several negative side effects when brought into a progressive timeline.

(And PERHABS it caused my quality problems of uploaded videos on youtube too...)


Is this true that only a ClipWrap ( a Machintosh based sofware) can transform Malignant PSF to Benign Psf with direct stream copy technology with the help of Quictime format?

Go back and read some of your old posts, we had this discussion before.

If your editor interprets it as interlaced, you interpret it as progressive. That's it. You can think of it as it "guessed wrong". No need to re-wrap

Believe me, Allan Tépper had right. The Malignant and Benign PSF are real existing problems. He wrote letter for Divergent Media. Divergent Media created the Clipwrap software and solved that problem for MAC users.

Yes I know it's a problem. The stream is encoded as interlaced. The problem is the editing software, and how it interprets the file . You can't change the method of encoding without re-encoding the file

Clipwrap doesn't help with youtube results - those files are still deinterlaced. Clipwrap only "solves" it for FCP, FCPX
(but you can do the same thing for free on a PC or MAC by interpreting the file as progressive in the editor)

The main purpose of clipwrap is to allow Macs to edit other formats which they couldn't natively (e.g. FCP7 and below can't edit AVCHD without log & transfer & reencoding to prores)

I thought perhabs Youtube handle better the quictime mov files..... Is the code what you posted acceptable for the Avanti gui of ffmpeg?

The only solution is a lossless ffv1 codec in planar 4:4:4 and the HDMI output of my camcorder with a "HDMI to USB3 converter". I had to buy a big fast SSD disk for my laptop... and record native quality progressive CMOS raw video of the camcorder....

Only solution for what? You can just interpret it as progressive in your editor - this is how everyone else does it

For youtube, you can re-encode it as progressive

Most consumer HDMI ports aren't Y'CbCr 444, they send a 422 signal . You can take your AVCHD and re-encode it to ffv1 420 right now (But if your HDMI port works with live recording, the benefit would be better subsampling, no lossy AVCHD compression)

No it doesn't. Because the stream isn't changed when you re-wrap it - field_pic_flag is still set to 1

For the youtube case, it even messes up native progressive AVCHD clips - what you call "benign" where the field_pic_flag is still set to 0 . Even though editors "see" it as progressive, youtube still can mess it up

The ONLY solution for youtube that works in EVERY case is to re-encode

OK, I sent you the URL of the original video in private message. How can I set the video flag from 1 to 0? Are there any software to do that?

Can I use your ffmpeg code in AVANTI gui?

You can't change the flag without re-encoding. (At least I don't know of any software that can)

I asked for the clip before I understood exactly what you're trying to do - re-wrapping won't help you . Yes you can rewrap to MOV, but the stream is still encoded as interlaced. You can't change that without re-encoding. You can use whatever editor to treat it as progressive and that works , and is many times faster and free

Believe me I've tested this many many times with many many programs

And youtube is a special case - it even messes up native progressive AVCHD clips as well (clips which are treated as progressive in editors) . It might be that they fix this in the future, but I tested this just a few days ago and it's still like that

I've already explained the options above

I uploaded here: http://dictaphone.atw.hu/00001.MTS

For the correct playback of PSF videos, use MPCHC with the Coreavc or LAV codec as external filters with the following options as depicted by the photos: http://dictaphone.atw.hu/coreavc.png http://dictaphone.atw.hu/lavvideodecoder.png

Can you upload the original MTS to youtube to see the problems?

what cam is it? it's not very editor friendly, you should probably stick to shooting 25i. i work with canon hv20/30/40 psf 30p all the time and all that's needed is to interpret the footage as progressive in any editor. your's won't work in vegas pro even after interpreting the footage as progressive. the only editor i found that deals with it properly after interpreting footage as progressive is premiere cs5.

Canon LEGRIA HF G10

It has a sharp picture? Hasn't it ?

[aedipuss]

it gets good reviews. but the video shouldn't show up as 50i/50p in an editor when it's really 25i/25p. it crashes vegas pro when trying to render it.

did you upload an original sample that had nothing done to it?
