I'd want to mantain my footage original frame rate, 50i, in the conversion process.
Is this possible?
TIA

the cam is a canon hf10

puzzled
I've already red that article, it's not clear if the result is 25 or 50 fields per second...
Is the AIC clip, obtained with the conversion in iMovie, 50i? Is it 25p, 50p? I can't see interlace! Is deinterlace already applied?
Where is the limit for the 25/30 fps project in iMovie? I would be able to see in Quicktime inspector the difference between frames and fields per second...
I've tried VoltaicHD earlier this year, but it's expired and I've trashed the trial clips obtained from avchd conversion.
I want to buy your program but I want to be sure of the result and of the differences with my actual workflow.
TIA
50i
I had Problems getting my .mts converted in 50i.
Quicktime says always 25 fps. with all codecs...
What do I wrong?
cam is sony xr 520 ve

50i conversion
Hi Durin,
VoltaicHD preserves the format that your movies are shot in. If you shoot in 50i, you will get a 50i AIC file from Voltaic.
Likewise, if you shoot in 25p on your HF10, you will get a 25p AIC movie.

50i not for me
sorry, replied the wrong post. see above.
(50i don't work for me)
and then?
when i get a 50i AIC file from Voltaic, can i edit it in imovie '08? or it will became again 25 fps?
Thanks
editing in iMovie
You will be able to edit the 50i AIC file in iMovie 08, however it will treat it as 25fps and run a de-interlace filter over the movies.
The movie that you see in the preview will be de-interlaced and the iMovie export will de-interlace once you are done.
Keep in mind that a 50i movie is still 25 frames per second (this is what Quicktime will tell you). The interlaced nature of the movie means that there will be 50 FIELDS per second, which is different.
The short answer to all of this is that interlaced footage gets converted to progressive by iMovie.
Interlaced footage is only useful if you are editing in 50i and exporting the final result in 50i to a device that can play native 50i. The only thing that can play a true 50i signal is a HD TV since they have hardware support to play this.
50p
ok now, if i have 50i (or 60i) clips from an HD camera device
can i export them to 50p (or 60p)
and if not: WHY NOT?
second best thing would be to keep it interlaced as it's better then losing half the fps.
It's exactly what i want to
It's exactly what i want to do: shooting in 50i, editing in 50i, exporting in 50i and playing in 50i, TRUE 50i, not a 25 fps with doubled frames.
The solution should be FCE 4, but i'm searching for a cheaper solution (i use very basic editing: cut, join, titles).
Could VoltaicHD help me to create such a workflow?
Native AVCHD editing in VoltaicHD
Hi there,
version 2.0 of VoltaicHD will support trimming and joining of clips only. The output will be limited to the formats that we currently support (i.e. all Quicktime codecs).
In versoin 2.1 of VoltaicHD we plan to introduce exporting to AVCHD. This will take your AVCHD clips, let you trim and join, and produce a final AVCHD output movie. In this case we will be preserving the original footage and just trimming and joining.
This 2.1 process will give you the best possible quality since no footage ever gets converted.
We're still a few weeks away from releasing this, but for people wanting that "best possible quality" output (like us) we think this will be a big move forward for AVCHD editing on the Mac.
Once VoltaicHD is bedded down with the new AVCHD features we will add them to FlamingoHD. FlamingoHD is where we plan to add other supporting features like Titles and Transitions.
fps
How can I be sure if a clip is 25p or 50i if Quicktime tells me 25 fps in both cases? I can see the interlace, but what about the number of fields?
50i workflow
I've found this article on interlaced workflow using iMovie08
http://pond.org.uk/misc/imovie_and_hd/workflow.html
As the article points out, only try this if you have a very good reason. Otherwise stick to progressive.
The missing piece from this article is how to achieve interlaced HD playback on a HD TV. I know of only two ways to do this and that is using a AVCHD DVD on a Blu-ray player, or using a straight AVCHD movie on a PlayStation3.
To create an AVCHD output file you need Final Cut Pro (apparently). We've got FCP at ShedWorx but haven't figured this all out yet. Its not easy!
Finally, the simple answer to all of this is native AVCHD editing. No conversions, so import/export/transcoding.
Version 2.0 of VoltaicHD for Mac will have simple trim and join native AVCHD editing. In version 2.1 we plan to add AVCHD exporting also (from AVCHD source). While only a simple editor, this workflow will give you very, very fast native AVCHD editing.
This workflow requires no conversion to get started and its just (relatively) simple AVCHD file joining to create the final product. This will give AVCHD footage exactly as it was shot.
