Convert from 30fps Canon 5dmkII to 25fps...

[Gannjunior]

...the camera in question, is able to get HD video at 1920x1080 30fps 40mbit h264.

To get PAL video, it needs only framerate conversion, keeping the same resolution.

It's enough to get the best quality to use convertFPS(25) in avisynth?

tnks,
ciao!

Not well worded :) "best quality" is meaningless here.

Question 1 - Does your video have audio?

yes...nice question. Yes it has ! :)

I import in avisynth using QTinput.dll (needed to import .mov container). Since directshowsource doesn't work...So since h264 5dmkII is contained inside mov container I need the dll i mentioned before + quicktime 7 installed.

About the audio there is also the problem that importin the video at 30fps I noticed that it is not synchronized...

... QTinput("C:\Users\lorenzo\Downloads\mvi_0155.mov",color=1,audio=true,info=0) ....

Hmm.... there might be an issue there.

I'd try remuxing the MOV to MKV first, and then using DSS2(...) to load the MKV. DSS2 is part of avss.dll, which can be found in your installation directory for haali media splitter.

£2000 and it can't do 24p? (Never mind 25p - 24p would be close enough!).

It's a shame Canon never realised the "PAL" half of the world exists when it comes to frame rates on their digital stills cameras.


When you get the video into AVIsynth properly, there are lots of methods for converting the frame rate. IMO none of them are capable of maintaining the quality of your original video. You can have choppy motion (changefps), jumpy motion with blurred/ghosted frames (convertfps), or smooth motion with artefacts (motion compensated frame rate conversion with mvtools).

e.g.

http://avisynth.org.ru/mvtools/mvtools2.html

Search around this forum and you'll find plenty of script examples.

Agree!
Frame rate conversion is not recommended. You'll loose quality.
Make a Blu-ray (or compliant stream) and feed it to a modern LCD TV.

Sony makes the same shit!!
The morons really think that NTSC is the only system...
