hdv 720p25 sequence setting – ? help please
Hi,
I’m experiencing some extreme weirdness in fcp.
I’ve just gone through the following workflow:with HDVxDV: convert .m2t files (1280×720,16:9,25fps,progressive)
to quicktime using HDV 720p compressionwhich results in a quicktime which when i open up the movie inspector in quicktime player says: Apple HDV 720p25, 1280 x 720 and it says ” normal size 1280 x 1080 pixels”
now i want to bring this into fcp – if i simply drag a clip into the timeline, i get the “doesn’t match sequence settings” so i click “change settings”. A red render line the appears over the entire clip. Then i open the settings to look what it’s done and i see that the frame size is set to HD 1280×1080 16:9 as well as the pixel aspect ratio. The compressor is set to hdv 720p25.
if i click on “load sequence preset” and choose hdv 720p25, then suddenly the red line goes away, leaving me with a green line, and the video in the canvas changes size a little – there is now a black square around the video that looks like it’s 4:3 but the video is 16:9 with a blue line around it and looks normal.
but now if i drag another clip with the same characteristics into this sequence, it looks completely stretched.
does anyone know what’s going on or what i should set my sequence settings to? do i need to adjust something in the audio/video settings?
thank you!!

Hi Angela,
A real mess. I’v never heard of HDVxDV but I just had a look in Googles.
You may have choose wrong your preset. 1280×1080 corresponds to DVCProHD and this format uses his own pixels format.
But this is not the problem. You want to convert your HDV-m2t files in HDV-QT files.
I’m reading a manual of HDVxDV (https://www.lafcpug.org/Tutorials/basic_hdvxdv.html) and I don’t see the possibility to do that with this application. I don’t see the proper size in the setups, neither the HDV codec as an export option.
Why don’t you try with MPGStreamclip (Free!!). Just import your clips and select “export as QT Movie”.
Select Apple HDV 720p25 and done.

The quicktime export isn’t the problem, and you can export to quicktime with hdv 720p25 with hdvxdv no problem. (i used this because we used it to capture the footage from our jvc hd110 camera)
but now i want to know what my sequence settings need to be so that i don’t have to render the entire thing. the weirdest thing is though, is that in the fcp browser, the frame size it reports for these clips is 1280 x 1080, but when the frame size and aspect ratio are set to 1280×1080 in the sequence settings (compression hdv 720p), it wants to render the entire thing. but when i set the frame size to 1280×720 (HDTV 720p 16:9) and the pixel aspect ratio to square AFTER the clip is already in the timeline, then the red render line disappears, i can play in real time, and the image looks right. but then i drag in another of the clips and then that clip that i just dragged in looks totally stretched – ?
i don’t know what’s going on here.

[angela anderson] ” want to know what my sequence settings need to be so that i don’t have to render the entire thing”
The only way that your footage won’t be rendered is when the sequence setting math the clips setting.[angela anderson] “but when i set the frame size to 1280×720 (HDTV 720p 16:9) and the pixel aspect ratio to square AFTER the clip is already in the timeline, then the red render line disappears, i can play in real time, and the image looks righ”
The Red Line just means that your clip can’t be played in RT. When disappear doesn’t means that do not needs to be rendered. Just RT for preview. try a Render All (ALT-R) an see what happens.The first think you should do is to see how FC is interpreting the footage in the Browser. Many times you need to set some parameters manually.

I am still not sure what sequence settings to use for my hdv 720p25 clips. like i said before, the browser says that the frame size is 1280×1080 but then where does the 1280×720 come in?
help, i don’t get it.

1280×720 is just a standard HD size when working with Square pixels.
What do not makes any sense is 1280×1080. Where are those numbers coming from? I’ve never before sow those proportions but in the manual of HDVxDV that I mentioned before.
in HDVxDV appear in a preset for DVCProHD, but you will never be able to get a 16×9 movie with that size using DVCProHD, HDV or Square pixels.
When you double click a clip in the Browser, how it shows in the Viewer window? Keeps the prper 16×9 aspect?

I want to Export a Image Sequence from a Editing based 50 fps Timeline and I am experiencing weird behaviour.
The frames are only exported from 2 to 2, this means that it only exports half of the frames (which results in a slow motion effect that I do not want)
This material was shot in a Panasonic P2 HDV Camera and the project and the timeline are in DVCPRO HD 720p50.
I don’t understand what is happening, but it looks like it is only exporting 25 fps.
I have try to put the sequence in the Apple Intermediate Codec in order for it to be more reliable (in frames count) but when I export the image sequence de same happens, as well as the same number of frames are exported.
I hope some one can help me.
Thanks for your attention
