Dear,

Editing MTS camcorder video files (1920x1080). Is there a big difference of quality between the export options:

A/ exporting quickly (the first option, in dutch it is called 'snel exporteren')

1280x720

6074 kbps,

30 frames/sec

B/ adapting (apparaten aangepast) the export myself to

1920 x 1080

14.945 kbps

25 frames /sec

Logically I would go for B/ as it is equal to the original.

This option gives bigger files, what I understand.

But why isn't this one of the main options?

And what is the damage when exporting to A: with smaller frame definition, more frames/sec (!?!) and a much lower bitrate.

Both have the MP4 extension.

Secondly: it is only possible to export to Avi in 720x576. format. Why? I do not understand.

Thanks and kind regards,

Patrick

Simply put, 1280x720 is not full HD. It has less than half the resolution of 1920x1080 -- which is why it is a smaller file. Lower resolution means less clarity -- especially if you watch it full screen on a computer or HDTV. So if by quality, you mean how sharp the picture is, there is a lot of difference.

If your original footage is 1920x1080 and your project settings are 1920x1080, you'd be best to output 1920x1080 if you're showing your video online or on a computer or TV.

You don't say what operating system you're using, but you should be able to output 720x576 in any of several formats, including MP4. If you don't see several options, I'm not sure why.

Thank you. I must have hoped that an 1920x1080 recording could be exported to a lighter video format without loosing image quality (clarity, sharpness, ...) due to better compression methods etc.

So the only best format to export to departing from MTS is the 1920x1080, I start to understand?

I'm not sure what Adobe Premiere Light is and what its capabilities are.

But if your original footage is 1920x1080 MTS and you import it into a 1920x1080 Premiere Elements project, your should export your final video as 1920x1080 MP4 to maintain its full quality as much as possible. It's not more complicated than that.

Oh thank you. That is what I startedt to realize after your and other reactions here.

It is Premiere Elements, sorry.

I was only hoping at a certain moment,a time ago, that there should exist a way to save in a smaller size and still have the (nearly) same quality. In fact it is very confusing because the app makes a few propositions (I have it in dutch and I'll translate): the option for TV for example: in the commentary it is said that this is good to exchange high quality Video. O, Nice. But the frae tae they propose here is 29,97 Fps. It is misleading as long you do not understand that you have to go via nother menu to adapt the Fps for example. Even the very first option

And if you choose to upload to Vimeo for example it proposes 1280x7200 (but it is titled as HD) and also 29,97 fps. The footage is shot at 25fps. So I imagine it is not the most sane situation to upgrade the Fps from 25 tot 29,7... ? i allready uploaded to Vimeo in the fullest quality and best parameters in H246 and they automatically recompress. So, their recompressed material will be good enough for the online viewing but not enough to be projected on a big screen big format for an audience of 400 people for example, I presume? Or are they capable to compress the video in a way that nobody sees the difference?

First of all dont mix framerates.

Filesize = bitrate x duration

If your original files are 30 fps and your project is too you wont get 25 frames in the export. You need to go into the advanced setting.

But do not export 30 fps to 25. Wont look good.

Set your camera to 25 fps.

Avi as in dv avi is Standard Sefinition which is 720x576. There is no other format.

Thank you. During many years AVI as the best format to export to. When you film in .mts and export to AVI, the quality will be excellent (lossless?) but only in a lower frame size, am I right? But I presume it is ridiculous to export to an Avi-format unless if my recordings are from a time that 720x576 was the only format. I am a bit away from my original subject now: I archievd digitaly a lot of video's I made in the late 70's. The format that I digitalised it to was a little bit guess-work as I did not know: From an analogue SVHS to a digital file = which format to choose? I Understand that the frame rate ha-s to be thesame, no?

If you want to archive old VHS, mp4 would be the way to go now.

No point in exporting to dv avi as you cannot play it anywhere but on a computer.
