PAL and NTSC???

[John Rofrano]

This won’t affect anything negatively. It’s just bad metadata. As you said, the video is still PAL and will be fine. I wouldn’t worry about it since Vegas Pro has had this bug for many years and everyone who is making PAL videos for the web has been unaffected by it.

Alright, thank you so much. I found out everything I needed to know.

Thank you!

I have a related issue. I shot footage with my iPad, which is H.264, 1920×1080, Progressive, 30 frames per second. (Seems to me, it is neither NTSC or PAL.) I edited the footage in Final Cut Pro X, with the project’s render properties set to ProRes 422 (HQ), because there seems to be no way to natively edit H.264. I created a ProRes master file using Final Cut Pro X’s Share feature, because I like to use Episode for encoding to H.264. I am not changing the video properties (1920×1080, Progressive, 30 frames per second) anywhere in this workflow. MediaInfo says the resulting Episode encoded H.264 video is the PAL standard, which makes no sense to me.

It is merely an annoyance, I guess. The video seems fine. But I do wish that I could figure out where the problem is being introduced. (By Episode?)

P.S. I am using Final Cut Pro X Version 10.0.9 and Episode 6.3.1.23, outdated versions because I am keeping Snow Leopard on the particular iMac that I am using.

PAL standard, which makes no sense to me.

Again, I show only what the encoder says. Nothing else.
If you want a confirmation, please provide a sample file and I’ll show you the “trace” of the bitstream.

The video seems fine.

Most players don’t care of this bitstream field.

[John A. Mozzer] “I have a related issue. I shot footage with my iPad, which is H.264, 1920×1080, Progressive, 30 frames per second. (Seems to me, it is neither NTSC or PAL.)”

That’s right. NTSC and PAL are “broadcast” standards. Most Internet devices (like tablets and smart phones) ignore broadcast standards and shoot whatever they want. I would say that 30 fps is closer to NTSC than PAL. But some devices use variable frame rates which give you crazy results.

[John A. Mozzer] “I edited the footage in Final Cut Pro X, with the project’s render properties set to ProRes 422 (HQ), because there seems to be no way to natively edit H.264.”

You can edit native H.264 if you upgrade to the latest version of FCP X.

[John A. Mozzer] “It is merely an annoyance, I guess. The video seems fine. But I do wish that I could figure out where the problem is being introduced. (By Episode?)”

It’s not a problem if the video is fine. As I said, broadcast standards are often ignored for Internet video anyway. I wouldn’t get hung up over them.

Jerome, I am glad to know that is what MediaInfo is doing, because I didn’t know before reading this thread. Yes, I would like to provide a file and see the trace.

[John A. mozzer]

John, thanks. Good to know that I’ll be able to edit native H.264 when I upgrade to the latest version of FCP X.

in your file, video_format is set to 1 (so PAL).

Thanks, Jerome. This is good to know. I’ll contact Telestream’s customer support to see whether they can explain why the Episoder encoder is apparently putting a video_format field set to 1 in the bitstream.
