hdv2 format

[Razorholt]

Hello there-

I'm trying to compress a MOV HD file using avisynth but It doesn't show the video. The format is hdv2.

Load_Stdcall_plugin("C:\Program Files\AviSynth 2.5\plugins\yadif\yadif.dll")
QTinput("D:\Ep107-HDV 1080i60.mov",quality=100).converttoYuy2()
Yadif()

The video doesn't play in regukar Quicktime player but plays in SMPlayer. Am I missing a component or something?

I also tried with QTReader() but with no avail.


Thanks.

QuickTime on Windows requires the MPEG-2 component, and I've never gotten it to work correctly.

Here's how I work with bizarre HDV QuickTime MOVs in AviSynth -


mp4box -raw 1 file.mov


This strips the video stream into a ".hdv2" file, which is just an MPEG-2 Elementary Stream that can be safely renamed to .M2V. Then I can load this into DGIndex, and process normally :)

YES! :) Thanks a lot !!

Quick question: I also extracted the audio and ended up with a .TWOS file. How do you take care of that one? None of my sofware is able to understand it.

Thanks,

ffmpegsource might just work as well.

edit, about twos

I tried this with a quicktime file and I got a .xd5b file format. I tried renaming it to .m2v .mpg and .mxf with no luck at all.

This is a 100 mbit 4:2:2 color mpeg2 file from an up coming video device. The device uses a regular mpeg2 encoder but wraps in into a quicktime format.

@Razorholt - rename to WAV and treat as such :)

@Smetvid - that's odd. XD5B looks like XDCAM, which should be fine if renamed to M2V and loaded into DGIndex. What happens when you feed DGIndex the file?

Wow! that actually worked. Thanks a lot. Now the only problem is figuring out how to bypass needing to encode the file to a new PC friendly format to use in a NLE. It would be nice to just change the raw stream without encoding but at least now I have an option without going out and buying a Final Cut Pro machine just to convert video files.

Anybody else know of a tool to just turn the raw video stream into a proper m2v file without encoding?

[Blue_MiSfit]

???

You did just turn the raw video stream into an M2V file. There was no encoding happening here, you're literally demuxing the MPEG-2 video from the MOV container into an elementary stream.

What exactly is your goal?

Nevermind. I only did a save to d2v file and not the save to d2v and demux. Now I get the d2v index file to use in avisynth and I also get a m2v file to use in my nle. Thanks a lot for the help.

No problem! Enjoy..

Thanks Blue_MiSfit! Problem solved for me too :)

@smok3: ffmpegsource looks interesting, I will try it tomorrow. Thanks!
